APOLLO 17 MISSION COMMENTARY 12/6/72 CST 19:30 GET -01:22 1/1 

LAUNCH CNTL This is Apollo Saturn launch control we're 
at T minus 1 hour 22 minutes and counting. Cabin purge has 
now been completed and the boost protective cover has been 
closed. The 65 percent nitrogen 35 percent oxygen mixture 
will now be enriched to a 60 40 mixture at liftoff. Just 
completed were some preflight command tests with the Manned 
Spacecraft Center in Houston. These tests are to insure that 
Houston can send commands, and that they are being received 
on or by the launch vehicle. Also just completed was a first 
motion signal. This is the first motion of the vehicle as 
it lifts off the pad. A test signal is sent to the eastern 
test range and to the Manned Spacecraft Center in Houston to 
assure that they will get this signal at liftoff. Also, we 
just received a final go for a Jimsphere release. The Jim- 
sphere is a weather balloon which is the final weather bal- 
loon to go up before launch indicating the wind direction. 
C-band beacons are in check at this time. The C-band beacons 
aboard the launch vehicle are used in tracking. They give 
indications of range velocity during the power phase of flight 
Que ball sim command was just sent. The que ball is an angle 
of a tacmeter which is purched above the launch escape system, 
and it's read by the spacecraft commander in the spacecraft. 
It would indicate any deviation from the plan flight through. 
It reads zero as it sits on the pad and during the test a 
simulated command is sent to it, and Gene Cernan in the space- 
craft reads off what he is reading in the spacecraft during 
that sim command. The checks in the spacecraft continue to 
run somewhat ahead of schedule. The spacecraft test con- 
ductor Skip Shovin indicated their running ahead and looking 
good to which Cernan reply we're looking good up here too. 
The countdown continuing to move along well at this time 
T minus 1 hour 21 minutes and counting. This is Kennedy 
Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/06/72 GET 01:12 CST 19:40 MC2/1 

LAUNCH CNTL This is Apollo Saturn Launch Control 13 minus 
1 hour 12 minutes and counting. At this time Spacecraft Commander 
Gene Cernan and the Spacecraft test conductor Skip Chauvin are 
going over some command checks. During these checks the Space- 
craft Commander actually gimbles or moves, swings the main engine 
in the Service Module. He does this using his flight hand con- 
troller and this is a system which is done so that if there is 
a problem with the computer which normally flies these, he can 
take over and manually fly it. Normally, however, all burns 
of this engine are done by the computer. Out at the pad, the 
space vehicle is surrounded by searchlights producing some 
225 foot candles of light, a total of 72 20 kilowatt zeon lights 
and 2 60 kilowatt zeon searchligh banks provide this illumination. 
At liftoff, approximately 7500 foot candles will be produced from 
the flame of the Saturn V first stage engines. This is almost 
equivalent to daylight. Searchlight will also illuminate the 
Apollo 17 for the first 60 feet of it's flight. Countdown con- 
tinuing to go smoothly now as we approach the 1 hour mark. T minus 
1 hour 11 minutes and counting. This is Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 1276/72 GET -01:00 CST 19:52 MC3/1 

LAUNCH CNTL This is Apollo Saturn Launch Control. We're 
at T minus 1 hour and counting. T minus 1 hour and counting. 
Just completed were the C-band beacon checks. These are checks 
of the beacons, two of them aboard the instrument unit of the 
space vehicle. These are used in conjunction with C-band radar 
here at Kennedy Space Center to check the space vehicle during 
powered phase of flight. A check was just made with the superin- 
tendent of range operations who ran through the camera coverage 
looking at the weather around the various areas to see what 
camera coverage, and that appears to be satisfactory. Meanwhile, 
at the pad, the closeout crew has completed securing the white 
room area, and they are clearing the pad area themselves at this 
time. Just before they left, they indicated to Cernan that they 
were completed their jobs going back away from the pad area. 
Cernan said "We'll see you when we get back." The pad leader 
responded that "The next face you see had better be a frogman or 
you're in trouble." The weather appears to be satisfactory. We've 
been tracking some local buildups, but at this time they're just - 
they do not seem to be posing any problem for an on-time launch 
at 9:53 p.m. EST. Now, T minus 59 minutes, 32 seconds and 
counting. This is Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 -0:55 GET 19:57 CST MSC 4/1 

LAUNCH CONTL This is Apollo Saturn Launch Control. 
We are at T-55 minutes 54 seconds and counting. Stoney, 
astronaut Bob Parker, the capsule communicator here in the 
firing room who has a variety of of functions during this 
mission; one of which is to set the elevators at the 320 foot 
level. He actually commands the elevators which are part 
of the egress system, emergency egress system, for the 
astronauts. He has just reported that the elevators have 
now been set at the 320 foot level. In an emergency the 
crew could come out of their spacecraft into these elevators 
where they would be lowered at a high speed, 600 feet per 
minute, to the ground floor or A level floor where they 
can exit from there into a variety of escape modes; one of 
which would be down a chute into a blast danger area or 
a safety area, or they could continue on out and be picked 
up by armored carriers. Underway at this time with the 
launch vehicle are some checks of the secure range safety 
systems aboard the vehicle. These are actually checks of 
the receivers in that system. A range Safety Officer could 
terminate the flight of Apollo 17 if it became irratic by 
initiating emergency cut off, or if necessary a propellant 
dispersion command. These systems are located on each of 
the flight stages. There are three stages of the Saturn V. 
Two receivers in each stage, and they would receive a signal 
from the range safety officers and then sending through 
them to through these receivers, they could perform the propel- 
lant dispersion. These actions, of course, will be taken only 
if the vehicle were so irratic that it were endangering 
some land areas, and of course, only after the crew had 
used one of the escape options open to them. The test 
going well at this time. Our countdown continuing T-54 
minutes 6 seconds and counting. This is Kennedy Launch 
Con t r ol . 


APOLLO 17 MISSION COMMENTARY 12/6/72 CST 20:02 GET -00:50 5/1 

LAUNCH CNTL This is Apollo Saturn Launch Control at 

T minus 50 minutes 55 seconds and counting. Preparations 
are underway in the launch control center at this time for 
a critical power transfer test. The space vehicle at this 
time is being fed from an external power source, but shortly 
before liftoff it will be transfered to the internal flight 
batteries. This test is to ensure that all electrical sys- 
tems aboard the vehicle function properly on the internal 
flight batteries. The test takes about five minutes during 
which time the various elements of the launch team monitor 
thier systems and report in then to the test supervisor, 
Bill Schick here in the control room that everything looks 
good during the test. Depending on local weather conditions 
the various areas around the United States, the flight of 
Apollo 17 will be monitored or be able to be seen by people 
as far as 500 miles away. This is the flight as seen of 
the first stage of powered flight. This would include a 
large portion the southeastern United States, northern 
tip of Cuba and the Bahama Islands. The power transfer test 
is now underway; first stage, second stage, third stage, 
instrument unit now all going to internal power. Count down 
continuing to go well T-minus 49 minutes 35 seconds and 
counting. This is Kennedy Test Control. 


APOLLO 17 MISSION COMMENTARY 12/06/72 GET 00:45 CST 20:06 MC6/1 

LAUNCH CNTL This Apollo Saturn Launch Control, we're now 
T minus 45 minutes 55 seconds and counting. Various elements of 
launch team reporting in to test supervisor Bill Schick, that 
they experienced no problems during the power transfer. We now 
transfer back again to an external power source, which will feed 
the vehicle systems until approximately 50 seconds before liftoff, 
at which time the final power transfer to internal takes place. 
At the T minus 45 minute mark, we'll be watching for swing arm 
number 9. That's the swing arm which gives access to the Space- 
craft to swing back to a retract position, 12 degrees back from 
the Spacecraft. This is a park position, a standby position, 
where it remain down until the final moments of the countdown. 
T minus 5 minutes, it swings back to the full retract position. 
Once it swing backs, the launch escape system aboard the a-, 
atop of the Spacecraft can be armed and this system could be 
used to pull the Astronaut crew to safety in any disaster. Now 
T minus 44 minutes 52 seconds and counting, this is Kennedy 
Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 GET -00:41 CST 20:11 MC7/1 

LAUNCH CNTRL This is Apollo Saturn - This is Apollo 
Saturn Launch Control. We're at T minus 40 minutes, 51 seconds 
and counting. Swing arm number 9 just retracted a few minutes 
ago, and, as it retracted, the astronaut crew aboard the space 
field could feel it moving away from the spacecraft. Eugene Cernan 
the spacecraft commander commented, "We're really hanging out 
here in the breeze now." Spacecraft test conductor, referring 
to the weather indicated that that was just a small breeze. The 
launch escape system has been armed. The system now could be 
used to carry the astronauts to safety if necessary. It's also 
used during the initial phases of powered flight to carry the 
astronauts away in an emergency. It would fly away in a high arc 
pulling them to a height, enough so that their parachute systems 
could deploy, and they could make a normal landing. The system 
is about 33 feet long. The motor develops 147 thousand pounds of 
thrust. This is almost twice the amount of thrust of the Redstone 
rocket, which powered astronaut Alan Sheppard, America's first 
man into space. The countdown continuing to move along smoothly 
now. T minus 39 minutes, 36 seconds and counting. This is 
Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 CST 20:18 GET -00:25 8/1 

LAUNCH CNTL This is Apollo Saturn Launch Control. 
We're at T-minus 35 minutes 11 seconds and counting. Space- 
craft commander Gene Cernan has reported back to the space- 
craft test conductor Skip Chauvin. He said you've delivered 
us the best now it's our turn. Thank the guys we want to 
see them as soon as we can when we get back and I guarantee 
you we'll do that. Meanwhile C-band beacon checks are going 
on with the space vehicle. The liquid hydrogen liquid cxyge; 
fully aboard and being replenished at this time to ensure a 
full load at liftoff. Count down continuing to go smoothly 
as we approach the half hour mark T-minus 34 minutes 
34 seconds and counting. This is Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 GET 00:30 CST 20:22 MC9/1 

LAUNCH CNTL This is Apollo Saturn Launch Control T minus 

30 minutes 54 seconds and counting. Manned Spacecraft just in- 
dicated to the test supervisor Bill Schick that we are go for the 
terminal countdown sequences. Final propulsion checks have been 
completed and the C-band readouts, once again repeated have been 
completed. Beach boss reports the launch sight recovery force 
helicopters are on station and ready. Digital range safety com- 
mand checks are now underway as the countdown continues smoothly 
aiming for the T minus 30 minute mark. Now at T minus 30 minutes 
24 seconds and counting, this is Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 -0:25 GET 20:27 CST MC10/1 

LAUNCH CONTL This is Apollo Saturn Launch Control, 
T-25 minutes 54 seconds and counting. Command Module Pilot 
Ron Evans at this time has armed the reaction control system 
aboard the service module. He does this by allowing the 
hypergolic fuels to move down the lines to the engines. At 
this time he is reading out the temperatures, pressures and 
fuel quantities in that system. Our weather continues 
to look good. The major frontal area which had been of some 
concern earlier, has remained well west of the launch area 
also some smaller buildups which we have been monitoring 
do not appear to be coming close enough to cause any concern 
for our 9:53 PM launch time. That launch will be aiming 
Apollo 17 for the Taurus-Littrow area of the Moon. This 
area is named after the Taurus Mountains . These in southern 
Turkey and the Austrian astronomer, Littrow. The site is 
expected to yield some of the oldest and some of the youngest 
lunar samples returned during the Apollo flights to the Moon. 
Now T-24 minutes 50 seconds and counting. This is Kennedy 
Launch Control. 


APOLLO 17 MISSION COMMENTARY 6/12/72 CST 20:32 GET -00:20 11/1 

LAUNCH CNTL This is Apollo Saturn Launch Control 

T-minus 20 minutes 55 seconds and counting. Short time from 
now we we'll begin chilling the propulsion systems aboard the 
second and third stage of the Saturn V vehicle. This neces- 
sary to condition them for the flow of the super cool liquid 
oxygen and liquid hydrogen. Just a few moments ago the crew 
aboard spacecraft America was doing an updated weather fore- 
cast. Cernan reported I hope it's as beautiful out there as 
it is in here. Countdown continuing to move smoothly at 
T-minus 20 minutes 24 seconds and counting. This is Kennedy 
Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 GET 00:15 CST 20:37 MC12/1 

LAUNCH CNTL This Is Apollo Saturn Launch Control, T minus 
15 minutes 52 seconds and counting. The Vice-President of the 
United States, Spiro Agnew has entered the launch control center 
now. He'll observe the final portions of the countdown from here 
and also the launch. Arming and checking of the Service Module 
reaction control system has now been completed and in progress 
is the chill down of the S-II, or second stage start tank. Check- 
outs continuing to go well, some running a little bit ahead of 
schedule, all on time. T minus 15 minutes 20 seconds and counting, 
this is Kennedy Test Control. 







PAO We'll go ahead and start our post-launch 

conference at this time, Mr. Kapryan will give you a quick run 
down on the activities tonight. We do have to get him back to 
the firing room shortly, so I'm going to ask you to hold your 
questions . 

SPEAKER Turn the sound up please. 

PAO I'm going to ask you to hold your questions 

to a minimum if you can, we need to get Mr. Kapryan who's already 
had a long day, back to the firing room again. So we'll go ahead 
and get started. I'd like to introduce at this time the Director 
of Launch Operations at Kennedy Space Center and the Apollo 17 
Launch Director, Walter Kapryan. 

KAPRYAN Good morning, ladies and gentlemen. It's a 

real pleasure to be able to talk to you this morning even though 
it's somewhat belatedly. I guess I'll run down a little on how 
the count down progressed until we ran into the problem that 
caused - that caused the real delay. Just as we were about to 
pick up the countdown, we did encounter a problem with the - 
with the multiplexer in the first stage, which I believe I 
reported to you at the press conference some time back. And as 
it turned out, with the multiplexer we did change it out and it 
did not hold up the pick up of the terminal countdown at all. 
Shortly after the countdown started, we noticed that one of the 
batteries in the S-IVB apparently appeared to have a greater than 
normal open circuit voltage decay. A period of about 11 hours 
that we've been tracking it we had about a drop of one volt in 
open circuit voltage. This is somewhat unusual in our experience. 
We were quite concerned about that for some time, however, through 
analysis and getting back with Eagle Pitcher, the battery vendor, 
and going over the modification that had been made for the battery 
since Apollo 16, this was determined to be a normal situation 
so that problem went away. We then encountered a minor problem 
with - with the second stage. A helium bottle had a fairly large 
decay as compared to decay that was - pressure decay that was 
noted during countdown demonstration tests. When we run decay 
check during countdown demonstration tests, it decayed at the 
rate of about 50 psi per minute. When we ran the decay in this 
count, it had gone up to 92 psi, and allowable decay was 100 psi 
so we were still within spec, but we were concerned over the 
fact that we had had a change and what would cause a change. We 
went back and ran another check and found that the leakage was on 
the order of 100 psi. We cycled the check valve and 2 valves, took 
another decay and the leakage had dropped to below 90 psi, so we 
felt we were in pretty good shape. So, we went ahead with the 
count on that basis. We did have a minor problem with the IU. In 
running one of our software programs, and we did have a problem 
software timing which we didn't understand at first. We ran some 
simulation on the breadboard and we were able to put that one 
to bed in about an hours time. So that, in summary, was about 
all that really happened to us until we went into our terminal 
countdown sequence. And I think you probably already know exactly 
- just what did happen. At T-minus 2 minutes and 47 seconds the 


KAPRYAN countdown sequence failed to output the 

proper command to pressurize the S-IVB LOX tank. The control- 
room monitors noted it and immediately took steps to perform 
that p ress uri zation manually. This was done, and at the time 
that we had the cutoff, we were up to pressure and everything 
was normal. The problem was that since the TCS did output 
the command, the logic circuitry said that we really didn't 
complete all of the launch prep for the S-IVB stage, and we 
do have an interlock in our countdown circuitry that precludes 
the retracting of swing arm I which occurs at T-minus 30 
seconds if this has not occured, and that is the reason for the 
cutoff. Now, it didn't take us very long to determine that 
we should bypass this command failure and go through the 
p ressurization , manually, and go through the rest of the count- 
down, except we weren't completely certain that the final 30 
seconds would all work properly. We did have a problem. How 
did we know that the last 30 seconds would work properly? How 
did we know that once we started igniting the 5 first-stage 
engines that perhaps we would get a cutoff on one of them, which 
we wanted to avoid at all costs. So that was the time consuming 
feature in the delay. We performed the operation of installing 
the jumper which we were able to do in the firing room. We 
have a preplanned design where we can go in with banana plugs 
and put in jumpers to jumper any point in the circuitry that we 
desire to without having to go out to the mobile launcher, and 
that is what we did. The same jumper was installed in the 
breadboard at Huntsville, and the sequence was run through several 
times on the bread board, and everytime we had a successful 
- a successful run. We knew that there was in this particular 
card where we had the problem, there was a sequence that occurred 
at T-minus 22 seconds, the guidance alert sequence. We weren't - 
that's actually a discreet event. We were a little concerned over 
that one. Our logic told us that we could lose that and it 
would not interrupt the sequence what-so- ever. We went back 
to the bread board in Huntsville to demonstrate that. We 
actually cut that command off and ran through the sequence 
again with the jumper and everything worked fine. We had every 
assurance that the failure we had was in no way connected with 
engine start circuit, which is the one that personally gave me 
the greatest concern. Once we were satisfied that we had no 
problem in that area, we picked up the count and went on our 
me r ry way . 

QUERY Did you have a premature ignition? Did we 

see something - - 

KAPRYAN No, what you saw was a perfectly normal 

occurence for the condition we were in. When we have a cutoff 
at T-minus 30 seconds, there's an awful of something going on 
a lot of hydrogen being vented into the burn pond and it flames 
up quite a bit. It was a perfectly normal occurrence for the 
condition we were in. 

QUERY No squibs were ignited. 

KAPRYAN That's correct. It's perfectly normal Doug. 

PAO Down here. 


QUERY A couple of questions, please. Do we know 

why at this time the sequencer did not automatically cut in the 
p res s ur iz ation of the lox tank - the lox tank in the third stage. 

KAPRYAN Well, we're not 100 percent positive but 

we are fairly certain that we know. It could be one of 2 things 
We could have had a couple of diodes fail, or we could have - 
in the circuit board, we could have some spread pins. We make 
them check that for the countdown demonstration tests where we 
pull the drawer, the TCS drawer and then we reinsert it. And, 
we have had a history over the past several years, with printed 
circuit cards of this nature, having problems with pins being 
spread and creating opens for us. Now we think that's what 
happened, but I can't tell you 100 percent at this moment that 
that is exactly what did happen. 

QUERY (garbled) I don't understand what you said 

in reviewing the problem about the guidance alert, which is one 
of - one of several sequences that happen after T-minus 30 and 
why that was particularly worrysome, as far as getting a shut- 
down of an engine. 

KAPRYAN It was the one remaining event that was - 

in the chain that was driven by the relay driver that was 
driving the relays that were in - that the one relay evidently 
failed. Not the relay, but the circuit that failed. There's 
one relay driver that drove 6 commands, and this T-minus 22 
command was one command that since we shut off at T-minus 30 sec- 
onds we didn't get down to so we thought that perhaps we might 
not have that command and we wanted to make sure that by not 
having it we were still okay. 

PA0 Okay, Bill, we're getting a mike to you, over 

here . 

QUERY I don't that this is a question properly 

addressed to Walt Kapryan, but I would like to get an answer as 
soon as possible, on it we got - - 



QUERY This is a question properly addressed to Walt 

Kapryan, but I would like to get an answer as soon as possible on it. 
We got off two hours forty minutes late, when do we get back on the 
timeline and how do we do that? 

KAPRYAN I can't tell you exactly when we get back to the 

timeline. We will arrive at the Moon at the same calendar time as 
though we had lifted off at 9:53. The TLI , - We will target the TLI 
and we will make the necessary corrections -in the TLI burn to get 
us to the Moon at the same time that we would have gotten there, 
had we lifted off at 9:53. 

QUERY Unaudible. 

KAPRYAN Yes, I guess it varies a little bit. There are 

some variables, that when I left the firing room the last prediction 
was, that it was going to occur about 3:45 this morning. I think 
they were predicting 3 hours, 12 minutes, and 34 seconds after liftoff 
I don't remember how that compares with the nominal. 

SPEAKER Okay. Dwayne can you get Ed Pitts down here and 

then if we can get a mike over in this center column can one of the 
mike-handlers get the mike over to the center column? 

QUERY I'd like to know what the astronauts did, or 

talked about or anything, that was going on as far as they were 
concerned during the delay. 

KAPRYAN Well, of course, I was busy having sessions on 

resolving the problems. So, I personally did not talk to them, how- 
ever, the capsule communicator and my launch operations manager Paul 
Donally did talk to them, kept them up to date on the status of our 
evaluation and troubleshooting and they took it quite well, and just 
took advantage of the time to rest as much as they could. 

PA0 Okay. Stand by for just a second. We'll get 

this mike fixed. 

Q UERY Were you at any time giving serious consideration 

at all to letting the launch slip until tomorrow's window? 

KAPRYAN Well, when you run into a problem, before you 

get it resolved, you always have that concern. When we were about 
an hour into the - an hour and fifeteen minutes into the trouble- 
shooting, we knew that we would not be able to recycle for tomorrow. 
Or for today, rather. We never did get to the point where we gave up 
and say, it looks like we're going to have to quit. We knew we had 
quite a bit of time left, so we just worked the problem and didn't 
think about scrubbing. 

QUERY At that stage of T minus 30 seconds, did the 

astronauts go into any sort of emergency procedures in case they had 
to abort? 

KAPRYAN They didn't do anything any different than they 

do for any, for any launch. The abort is an every present possibility 
even if everything is going nominally, so nothing was done differently 
this time, from any other launch. 

PA0 Okay, let's take one more question from Doug 

over here and then we'll go to Houston. We've got some questions 
out there. - - 


3 hours, 12 minutes 

f ati gue-wis e , 
sleep p e ri ods 

3:45, is that E.S.T. or G.E.T.? 
It's E.S.T. The G.E.T. was predicted to be 

and 34 seconds after liftoff. 
Okay, do we have some questions now from Houston? 
Okay. You can go ahead. 

(Inaudible) at. What the effect may be on the 
if this is going to cause them any problems, and 
may be changed. Have you got any handle on that? 
Well, I don't have any handle on it. First of 
all, it's not going to create any big problems. As I had indicated 
earlier, they took advantage of the delay to get some rest. Of 
course, I am sure there is bound to be some additional tenseness not 
knowing how the thing is going to turn out. And with respect to 
their rest cycles, I guess you will have to address that to the flight 

wh a t 


Okay, let's come back here 

re going to 

to Kennedy and 
h ave t o cut i t 


get just a couple more and then we 
Dewayne can you get this up here? 

SPEAKER Dewayne, over here in the blue shirt, he's been 

waiting quite awhile. 

QUERY Due to the fact that TLI will be changed, 

how would this effect the timing of the whole mission as a whole. 
Reference to the EVA's and the transearth insertion. Would this change 
anything in the timing or just the G.E.T. be picked up? 

KAPRYAN It's not going to change anything. The EVA's 

and lunar activity will be exactly as scheduled. Now of course, the 
ground elapsed time when the spacecraft gets to the Moon is going to 
be different. But they're going to get there at the same time, that 
they would have gotten there, had we lifted off at 9:53. Now, I'm 
not certain how they're going to play that. If you recall, when we 
launched Apollo 14, we launched 40 minutes late. They of course 
the TLI correction to get to the Moon at the right time. And in 
order to simplify using the flight plan, I think they updated their 
G.E.T. reference, so that they were using a ficticious 
that put them back on their flight plan. 

Okay. We'll take just a couple more 


G.E.T. reference 

c ome 

g one 

to us 

down here 
tonight - 

and then we'll 

go to Houston. 
Kapy, did I understand you correctly 
No we had no light on. 

Did I understand you correctly, that 

Mary you

Do you all have a problem with the line getting 

Well if we - If you're having a problem with the

That we couldn't have gone tomorrow. 
If we had scrubbed at. the end of today's launch 
problems other than nearly to go through the 

line getting in to 

window, and had no ^ ^ ^ tnem mcany lo 

functions of recycling, we would miss the T minus 0 
an hour and a half, which says that we would have a

T-minus 10 minutes 55 seconds and counting. At this time 
some computer checks being run with the launch vehicle. The 
spacecraft has now gone to full internal power. Up to this 
point the spacecraft fuel cells have been sharing the power 
load with an external source. Also going on at this time 
are some checks of the astro com circuit. This is the 
circuit which is used by the launch operations manager 
spacecraft t est conductor Stony and the three astronauts at 
launch time. This is to ensure that they are not getting 
any extrenious voices or are having to listen to any of the 
other network which might be carrying on a conservation which 
they don't need at that time. Countdown proceeding smoothly

phases of the countdown various elements of the team reporting 
into Test Supervisor Bill Shick with the go no-go for launch. 
At launch time a water deluge system at the pad will spray 
water over the entire area of the pad, some 400 000 gallons 
of water. More than the average family would use in three 
years will be spread over the pad and the swing arms protecting 
them from the searing flames of the Saturn V first stage. 
Various elements reporting in now. First stage reporting 
they are GO. Range Safety, Superintendent Range Operations 
they are GO. Launch Operations Manager reports he is GO for 
launch. Launch Director Walter Kapryan has given a GO for 
launch. We've passed the 5 minute mark, T-4 minutes 55 sec- 
onds and counting and swing arm No. 9 now coming back to the 
fully retracted position. The launch escape system setting 
atop the spacecraft, spacecraft named America by the crew, 
now could pull the crew to safety if there were any problem 
while the vehicle remains on the pad or during the early 
portions of the flight. At the T-4 minute mark we'll be 
standing by for word from the Launch Vehicle Test Conductor 
Norm Carlson, giving a clear for launch for the launch 
vehicle ignition. At T- 3 minutes 7 seconds we'll go on an 
automatic sequencer. It's called the terminal countdown 
sequencer. The astronauts on the Astro com circuit now 
reporting and thanking the launch team for all their prayers 
and all their help. T- 3 minutes 55 seconds and counting. 
Apollo 17, the launch team wishes you good luck and God speed, 
reports the launch operations manager over the Astro com 
circuit. T- 3 minutes 40 seconds, the countdown continuing 
to go on smoothly. Once we go on the terminal countdown 
sequencer, the countdown will be automatic from there on out. 
The countdown sequencer will initiate the various functions 
from that time on; however, the men here in the firing room 
will be monitoring their consoles, watching temperatures, 
pressures, various readouts. They could override that 
terminal sequencer if necessary. Moving up now to the time 
when we'll go on that terminal sequencer. T-3 minutes 
10 seconds and counting. Spacecraft ready light has come 
on indicating that the spacecraft is ready. We are now 
on the terminal sequencer. Launch sequence has started. 
The flowing of that water on the pad will begin at the 
1 minute mark flowing on the flame deflector below the 
launch vehicle on the launch pedestal itself and along 
the swing arms which will be coming back at liftoff. 
Instrument unit ready light has come on. Emergency detection 
system ready light is on. All indications are we are GO for 
launch as we approach the 2 minute 30 second mark. Pressur- 
ization of the various propellant tanks now aboard the space 
vehicle is starting. At two, our second stage liquid oxygen 
tanks now pressurized. These propellant tanks are pressur- 
ized with helium to insure that during the flight the fuel

flows properly down through the engine. It's quiet here 
in the firing room now as the men are monitoring their con- 
soles, looking at the temperatures, checking pressures and 
a variety of parameters to ensure everything is in a GO 
condition. P res s ur i z ation continuing on the fuel tanks at 
this time we'll go to the critical power transfer at the 
T-50 second mark in the count down. At that time we'll 
transfer external power source to the flight battery aboard 
the space vehicle. The final action by the crew aboard the 
spacecraft America will be a final guidance alignment con- 
ducted by the Spacecraft Commander Gene Cernan. The flight 
of Apollo 17 will be able to be seen depending on weather 
conditions, some 500 miles away as it goes into Earth orbit. 
Pressurization continuing, liquid hydrogen tanks now aboard 
the second stage have now been pressurized, all propellants

LAUNCH CNTL This is Apollo Saturn Launch Control. 

We're holding at the 30 second mark. This was an automatic 
cutoff. Cutoff by the terminal sequencer as mentioned this 
sequencer initiates various actions. Each action must take 
place and must be completed before the next one can be 
initiated. If anything does not get completed in time there 
will be an automatic cutoff. This cutoff was automatically done 
by the sequencer. We're standing by now to check just what 
the problem was. Now at T-minus 30 seconds and holding. 
This is Kennedy Launch Control.

The safeing procedures continuing at this time. Up to the 
T-minus 30 second mark the countdown had been proceeding

be and appears to be good at that time. However, we had an 
automatic cutoff from the terminal countdown sequencer and 
we're standing by to see just what caused that automatic cutoff.

LAUNCH CNTL This is Apollo Saturn Launch Control. We're 

at T minus 30 seconds and continuing our hold. The problem was with 
the terminal countdown sequencer, which failed to give the com- 
mand to pressure, pressurize the third stage lox tank. The 
crew in the firing room, realizing this were seeing this happen 
pressurized the tank manually, but this did not happen fast 
enough to satisfy the automatic sequencer. As was mentioned 
earlier, during this sequence everything must happen at a certain 
time, before the next step in the sequence can take place. The 
next step that was to take place was the retraction of swing arm 
9 and at the time that was to take place the terminal sequencer 
had not had an indication that the third stage lox tank had 
been pressurized. The plan now is to recycle to the T minus 
22 minute mark in the countdown. Now this recycling procedure 
will take an additional 35 to 40 minutes. This still puts us 
well within our launch window. While we're recycling, we'll 
continue to review the data to determine just what the problem 
is and whether or not we can proceed from the T minus 22 minute 
mark for a launch later in the window. The crew aboard the 
spacecraft has been alerted to the problem and understand what 
is happening. They're standing by there at this time. Now at 
T minus 30 seconds and holding, this is Kennedy Launch Control. 

LAUNCH CNTL This is Apollo Saturn Launch Control. We're 

remaining still in the T minus 30 second mark. We'll remain here 
for some period. It will take approximately 35 to 40 minutes 
to recycle back to T minus 22 minutes, where we'll resume the 
count. To explain again what has happened was we were in what 
was called the terminal countdown sequencer. At 3 minutes 
7 seconds in the countdown we go on to an automatic system called 
the terminal countdown sequencer. This countdown sequencer 
initiates various actions, the final actions in the count. Each 
of these must occur on schedule and in sequence. Now what hap- 
pened at this particular time was, the third stage liquid oxygen 
tank was not automatically pressurized as it should have been. 
The launch crew here in the firing room, when they saw this, 
manually pressurized that system, but it was too late to satisfy 
the sequencer. The next event in the sequence was the retraction 
of swing arm number 1, swing arm going over to the first stage 
and at that time, the sequencer did not see that the tank had 
been pressurized and sent an automatic cut-off. So we had an auto- 
matic cut-off at the 30 second mark. We're standing by at the 
30 second mark to go back to T minus 22 minutes and we are re- 
evaluating the problem, looking at the, what caused the sequencer not 
to automatically pressurize that tank, seeing what that problem 
is and seeing if there is a possibility if we go ahead and do 
this manually early in the sequence, if that will satisfy the 

APOLLO 17 MISSION COMMENTARY 12/6/72 GET 00:30 CST 21:15 MC20/2 

LAUNCH CNTL sequencer and we can proceed. Now holding at

have been completed. We are now going through preparations 
for recycling to the T-minus 22 minute mark. Standing

LAUNCH CNTL This is Apollo Saturn Launch Control. 

We're continuing our hold at the 30 second mark. We'll 
recycle to the T-minus 22 minute mark. The T-minus 22 minute 
mark is chosen as the recycling point because this is the 
point where we start the chill down as was mentioned during 
that point in the countdown. We start the chill down of 
the second and third stages to prepare them for the influx 
of the liquid hydrogen, the cold liquid hydrogen and the 
cold liquid oxygen. This chill down has some very specific 
parameters and must be started at a certain time and cannot 
go beyond a certain time. So it's best to go back to that 
point in the countdown under these circumstances and to resume 
our countdown at the T-minus 22 minute mark. When a deter- 
mination is made that we can resume. Continuing to look at 
the data here is see exactly what happened. There is no 
indication of ignition. Ignition was scheduled to come at 
the 8.9 second mark. Here in the control room a number of 
the people were looking through the remote cameras which have 
the capability out at the pad of zooming in on specific areas 
and a number of people here were looking right at those first 
stage engines and there was no indication whatsoever of engine 
ignition. We're continuing to evaluate all the data at this 
time as we hold at the T-minus 30 second mark. This is 
Kennedy Launch Control.

this time busily preplanning the new launch azimuth. The 
azimuth now if we go at the next opportunity would be the 
81.06 degrees. This will be automatically fed into the 
instrument unit of the Saturn V vehicle from the Manned 
Spacecraft Center. All elements of the launch team now 
putting everything together, checking over data and doing 
their best to put us back into a recycle position ready to 
pick up the count at the T-22 minute mark. Still evaluating

We're continuing to stand by at the T-minus 22 minute mark. 
We've been given the word here in the firing room now that 
the count will be resumed at 11 p.m. at T-minus 22 minutes. 
At this time there still has not been a resolution to the 
problem, but we'll continue looking at that. We could con- 
tinue on counting down while this problem is looked at. To 
reiterate what the problem was; the terminal countdown se- 
quencer failed to give the command to pressurize the third 
stage liquid oxygen tanks. The crews monitoring this func- 
tion saw that that happened and immediately manually pres- 
surized the tanks, but this did not occur in time in the 
sequence and when swing arm one was to retract it had not 
received this signal. As a consequence an automatic cutoff was 
sent. There are several possible work arounds to this they 
are being looked into at this time, and we plan to resume 
our countdown at the T-minus 22 minute mark at 11 p.m. Now 
holding at T-minus 22 minutes. This is Kennedy Launch

arm to the spacecraft, remains at the 12 degree position it 
will remain there until the T-5 minute mark in the countdown. 
Going on at this time are the recycling of some of the vents 
for the liquid hydrogen and the liquid oxygen. These are the 
vents which allow the venting of the gases as there is some 
boil-off occuring. It is necessary to continue venting these 
to ensure they do not freeze in either an open or closed posi- 
tion. The countdown proceeding smoothly now. T-13 minutes

around the indication going to the terminal sequencer that the 
tank has not been pressurized, when actually it had been done 
manually. They are checking all of their data, however, to insure 
that this is the proper method to work around the problem and that 
this will result in a smooth countdown from here on. Now at

operations manager has gone over with the launch team their 
proposed solution a work around. The team appears to be 
satisfied that it is the proper one. They are now briefing 
management personnel on the problem and the work around. 
Out at the pad the liquid oxygen continues to vent from the 
vehicle and is replenished. Liquid hydrogen is also vented 
from the vehicle as there is some boil off. However, because 
it is quite a volital fuel it is vented through a burnpond 
at the side of the pad. That burnpond is at the north side 
of the pad and there it can be seen burning in a controlled 
condition at this time. This is a normal condition, actually 
during the day this burns in such a pure manner that it 
cannot be seen. However, at night it is clearly visible.

changes to their mission due to this hold period. Also, at 
the Manned Spacecraft Center they are continuing to update 
the flight azimuth as they get new times for the launch. 
Launch Operations Manager Paul Donnelly just went through 
quite an extensive briefing with the spacecraft test 
conductor to pass cm to the crew what they feel the problems 
were and how they plan to work around it. The crew aboard

LAUNCH CNTL This is Apollo Saturn Launch Control. We're 

continuing in our hold at the T minus 8 minute mark. At this 
time, it's been determined to take an additional 20 minutes, 
add an additional 20 minutes to that planned hold period. The 
reason for this is, the crews would like to take the work around 
that they have devised and at Marshall Spaceflight Center, where 
the Saturn V launch vehicle was developed, they have what is 
called a bread board or a system, which is similar to this one 
and run through the sequence and insure that it does operate 
properly. The crew aboard the spacecraft was informed of this 
additional 20 minute hold. They indicated that they expected 
to use all three stages of this Saturn V and they were happy 
to have the 20 minute hold if that was going to assure that all 
three were going to work properly. Now continuing our hold at 
the T minus 8 minute mark, this is Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 12/6/72 CST 22:40 GET -00:08 35/1 

LAUNCH CNTLE This is Apollo Saturn Test Control. We 
are continuing our hold at the T-minus 8 minute mark. The 
reason the T-minus 8 minute mark is chosen for this hold as 
mentioned earlier has to do with the chill down of the thrust 
chambers in the S-2 or second stage and the third stage. 
Both of these stages use liquid hydrogen, an extremely cold 
cryogenic fuel and the thrust chamber must be conditioned 
prior to flight so that it's ready at the time of ignition 
inflight to receive these fuels coming in. To achieve the 
proper temperature the thrust chamber chill down should not 
exceed 20 minutes, but it must be on for at least 7 minutes 
and 40 seconds. So rounding that off the hold was called at 
the 8 minute mark. We can continuously hold it at this point 
whereas if we continued on down we would have to watch these 
parameters very closely so that we did not exceed that 
20 minute accumulated cooling time. At this point we can 
continue our hold and that continuation can be determined 
by the problem and we can pick up then at any time or con- 
tinue at long as necessary. We're continuing that hold now 
at T-minus 8 minutes and holding. This is Kennedy Launch

in Houston. And the launch team here at Kennedy Space Center 
preparing to pick up the count. Hopefully, we will be given 
a go ahead to pick up the count in approximately 10 to 
12 minutes from this time. We are continuing to stand by 
waiting to hear from the testing going on at the Marshall 
Space Flight Center in Huntsville. To recap the activities 
earlier today the countdown picked up at 11:53 a.m. after a 
planned hold period picked up at T-minus 9 hours mark shortly 
after that time the pad was cleared and we began loading the 
cryogenic fuels, that's the liquid hydrogen and the liquid 
oxygen aboard the space vehicle. Those operations actually 
went a little bit ahead of schedule. The astronaut crew 
went out to the pad, enter their spacecraft, began checking 
it out and those operations also running a little bit ahead 
of schedule. We went on to our terminal countdown sequencer 
at the 3 minute 6 second mark as scheduled. Everything seemed 
to be proceeding fine. At the T-minus 30 second mark we got 
an automatic cut off. It was determined that this cut off 
came because p re s s ur i z a ti on of the liquid oxygen tank aboard 
the third stage was not initiated automatically as it should 
have been when it was done manually the terminal sequencer 
did not sense that this had been done and therefore gave the 
automatic cut off. We're working the problem right now con- 
tinuing to hold at the T-minus 8 minute mark. T-minus 
8 minutes, this is Kennedy Launch Control.

to hold at the 8 minute mark in the countdown. Still awaiting word 
from the Marshall Spaceflight Center in Huntsville, Alabama, and 
the result of the test being run at this time up there. Meanwhile, 
here in the firing room, all elements of the launch team are assess- 
ing their position. They are assessing the effect of the hold and 
this amount of hold time on each of their systems. Everyone, at 
this time, busily at work here in the firing room, also at the 
Mission Control Center in Houston, busy there with their flight

We're at 15 minutes past the hour continuing to hold at the 
T-minus 8 minute mark. The supervisor just indicated that 
we finally pick up the clock at the T-minus 8 minute mark 
in 10 minutes. Planning to pick up the clock at 25 minutes 
past the hour. The tests being run or have been run now 
at the Marshall Space Flight Center and indicate that our 
system is good the way it has been reconfigured. All ele- 
ments during this 10 minutes will be preparing their various 
systems to pick up the clock at the T-minus 8 minute mark. 
Meanwhile, at the Manned Spacecraft Center the flight con- 
trollers there also planning to pick up the clock. We just 
received a go from the superintendent of range operations 
indicating that the range has been cleared around the new 
flight azimuth. The Manned Spacecraft Center Houston flight 
indicates that they are go to pick up the clock at 25 minutes 
past the hour. Now at T-minus 8 minutes and holding this is 
Kennedy Launch Control. 


APOLLO 17 MISSION COMMENTARY 1276/72 GET 00:08 CST 23:20 MC 42/1 

LAUNCH CNTL This is Apollo Saturn launch control. We're 

continuing our hold at the T minus 8 minute mark. We have 
approximately 5 more minutes remaining in that hold. It has 
been determined that the workaround is a correct and satisfactory 
one. A bread board or a sample system at the Marshal Spaceflight 
Center was used to run through the entire sequence as it now 
c on f i gure d and that operated satisfactorily. What happened was 
the - during the terminal sequencer, the liquid oxygen tank was not 
pressurized automatically. When this was done manually, the 
indication did not get to the sensors in time so that we had an 
automatic cutoff. The liquid oxygen tanksaboard the third stage, 
it has been determined, will be pressurized manually early in 
the terminal sequence and jumpers have been installed so that we 
can then feed the information to the sequencer so that it will 
not have an indication that the LOX tanks have not been 
pressurized. This - a bread board situation of this has been 
constructed at the Marshal Spaceflight Center in Huntsville and 
this has operated satisfactorily. So, it's been determined to 
go ahead with our countdown on this basis. We'll be planning to 
pick up the count at the T minus 8 minute mark some 4 minutes 
from now. Now T minus 8 minutes and holding. This is Kennedy 
Launch Control.

through the - his team - a status report from his team at 
the Mission Control Center. That team all reported they are 
in a go condition. Now, at T minus 7 minutes 20 seconds and

T minus 5 minutes 40 seconds and counting. At this time 
the various elements of the launch team have been reporting 
in to Bill Shigby, test supervisor, indicating that we are 
GO to continue. Mission director Chet Lee just verified 
that we are GO for launch. Safety indicates that we have 
a GO. First stage test conductor, this is the man who 
has charge of those five first stage engines which will 
give us the lift off, has indicated a go for launch. 
Launch Operations Manager, Paul Donnley, also giving us a 
GO for launch, and finally the Launch Director, Walter 
Kapryan says we are GO for launch. We've passed the five 
minute mark now and swing arm number nine, this is the 
access arm to the spacecraft, is coming back to the full 
retract possition. It moves back along side the mobile 
launch tower and it will remain there now through the final 
portion of the countdown and the launch. At the T-minus 60 
second mark 20 nozzles will start flame deflector deluge 
of 13 000 gallons per minute of water pouring down on that 
flame deflector, so a great deal of what is seen at launch 
time, which looks like smoke, is actually steam as this 
water is burned off. This water's to cool the pad area 
and to cool the equipment along side the launch tower as 
the water also pours across the swing arms in the launch 
tower. We are approaching the 4 minute mark in the count 
down now, T-minus 4 minutes 5 seconds and continuing to 
count. At the 4 minute mark we'll stand by for a final 
GO from Norm Carlson, Launch Vehicle Test Conductor. He 
has given a GO. The Launch Operations Manager now switching 
over to the astro COMM circuit, this is the circuit that the 
astronauts, the launch operations manager and the spacecraft 
communicator will remain on. They have this private circuit 
to keep extraneous talk off of their circuit. They are 
checking in, they are checking in now on the astro comm 
circuit indicating that they are GO. Spacecraft has 
indicated they are ready. Instrument unit ready light has 
come on. SIC at the first stage preparations are now 
complete as we approach the 3 minute mark. There is quiet 
in the firing room now as the engineers and technicians are 
monitoring their consoles. They are monitoring the various 
rates, pressures, temperatures, they can over ride the 
terminal sequencer if they sight a problem that it has not 
picked up. We are on that terminal sequencer now, we have 
passed the 3 minute mark T-minus 2 minutes 47 seconds and 
counting as we are on the terminal sequencer. At the 
T-minus 50 second mark we will be looking for that critical 
power transfer. This is where we transfer from the external 
power source, which has been feeding the 3 stages of the 
launch vehicle to internal power to the flight batteries 
aboard the space vehicle. It's expected that they given

seconds after 

nominal orbit. The crew reported an orbit of about 93.5 by 89 
based on their onboard calculations and computations on the 

APOLLO 17 MISSION COMMENTARY 12/6/72 GET 15:00 CS T 23:43 MC 46/2 

ground show that we're very close to the nominal ninety mile 
nautical mile orbit. As a result of the late liftoff, the 
translunar injection will be a little bit earlier than the flight 
plan ground elapsed time but we don't have an update on this time 
yet. We expect that it will be on the order of 8 to 10 minutes 
early. We'll update that time as we get a later update. We 
would expect that the time of arrival at the Moon will be approxi- 
mately the same as the flight plan time in terms of Greenwich 
Mean Time. The ground elapsed time will be somewhat earlier and 
we expect that there will be clock update - a so called clock 
update - at some point where we make the clocks in Mission Control 
and aboard the spacecraft agree with the ground elapsed time that 
they would be showing in the flight plan. The net effect will be 
that we'll arrive at the Moon in a shorter ground elapsed time - 
in effect about 2 hours 40 minutes earlier than the flight plan 
would show, but at the same Greenwich mean time or local time 
here on Earth, that - that we would have had had we lifted off 
on time. We're in effect making up the time by speeding up the 
arrival at the Moon. The spacecraft at translunar injection 
will be going somewhat faster than a nominal liftoff translunar 
injection. Consequently, it will arrive at the Moon going 
slightly faster, and also somewhat earlier, about 2 hours 40 
minutes earlier in terms of ground elapsed time. This will also 
mean that the lunar orbit insertion will require a bit more 
energy to slow the spacecraft down and get it into lunar orbit. 
These details of course, will all be worked out in the time that 
we have before our lunar orbit insertion. And, when we get an 
updated translunar injection time, we'll pass that along

PAO This is Apollo Control at 24 minutes. 

Apollo 17 now in an orbit about 90 miles by 93 miles and 
everything appears to be nominal aboard the spacecraft and 
aboard trie launch vehicle, Saturn third stage. One add- 
itional impact of our late liftoff will be the loss of television 
coverage for the transposition and docking maneuver. The 
television coverage will not be possible because the ground 
track has shifted and we don't have the site coverage that 
had been expected for television. The translunar injection 
burn, reigniting the Saturn third stage to put the space- 
craft on its trajectory to the Moon, is now scheduled to 
occur at a ground elapsed time of 3 hours 12 minutes 35 seconds, 
or roughly 9 minutes earlier than the flight plan time. This 
again the effect of the late lift off. And we will be 
reacquiring Apollo 17 through the Carnarvon Tracking Station 
at a ground elapsed time of about 52 minutes 20 seconds, 
roughly 27 minutes from now. 

PAO This is Apollo Control now 32 minutes 

after the liftoff of Apollc 17 and we have loss of signal 
with the spacecraft, we will be reacquiring through the 
Carnarvon Tracking Station in about 20 minutes. And from 
the President of the United States we have the following 
message to the crew of Apollo 17. The message reads: As 
you set forth on the final Apollo expedition to the Moon 
I want to have my personal best wishes for a successful 
mission and safe return. I am sure your voyage, your 
scientific exploration, will be the crowning achievement 
in a program which has expanded man's horizons , brought 
great credit to your country and lifted the spirits of 
people all over the world. God speed to you all. Signed 
Richard Nixon. The flight Dynamics officer, continuing 
to process tracking data, following orbital insertions, 
reports that there is a small amount of out of plane error 
showing up in the orbit. This is believed is due to a 
small error in the instrument unit of the Saturn thrid stage. 
However, the orbi: is very close to nominal, about 90 nautical 
miles by 93 nautical - 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 35:00 CST 24:03 MC 48/1

good, both with respect to the spacecraft and with respect to 
the Saturn 3rd stage which must perform that burn putting 
Apollo 17 on its trajectory toward the Moon. At 34 minutes, this 
is Apollo Control Houston. This is Apollo Control. The post-

PAO Control at 51 minutes into the flight of 

Apollo 17 and we're standing by to reacquire the spacecraft 
through the Carnarvon, Australia, tracking station. One of the 
things the booster engineer will be looking for when we reacquire 
them and get good log on the data will be the Saturn 3rd stage 
instrument unit. Looking at one brief bit of data before we lost 
signal, it appears that one of the four batteries in the instru- 
ment unit had a very high current drain on it. We will be look- 
ing closely at that to see if it was simply a telemetry problem 
or if, in fact, that battery does have some problem. And we 
should be about 15 seconds from reacquiring. 

SC Hello, Houston, how do you read 17? 

CAPCOM 17, read you loud and clear. 

SC Hey, we're going real well up here, Bob. 

Have no significant anomalies as yet and we've just about com- 
pleted our part of the insertion checklist. Gene has his S CS 
check yet and Ron's got some P52 numbers for you and the only 
thing I've seen so far is some spurious master alarm without caution 
and warning that seem to be associated with moving switches on 
p an e 1 2 . 

CAP COM Okay, can you get a sudden (garble) switches 

anywhere, anytime they switch it on? 

SC So far it's been fairly random. Some that I 

remember is the secondary cooler loop evap switch, the lamp 
test switch, let's see - I think I got one with the TEMP and auto 
switch. Gene got one doing something - I can't remember exactly 
what it was. 

CAPCOM Okay. Jack, we're standing by for that P52 

data. We've only got about a 4 minute - or a 5 minute pass here. 
We'll take the P5 2 data and I got a few updates for you. 

SC Okay, 52 data is coming. NOUN 71 is 24 and 30, 

905 is .01, 993s are plus .080, plus .029er, plus .018, and 
retort at 3525. 

CAPCOM Okay, we copy that. Okay, while we're 

filling in some here, you might want to know this, Jack, your 
sunset and sunrise times in the launch checklist are all off by 
8 - approximately 8 minutes and 30 seconds. That every - sunset 
and sunrise will occur about 8 minutes and 30 seconds sooner than 
in the launch checklist. That's an approximate number. Okay, 
we got you. 

CAPCOM Okay, and on page 2-17 of the launch checklist, 

you're going to want to delete all reference to Honeysuckle, AOS 
and LOS , and delete all reference to Canary's AOS and LOS. 

SC Willco. 

CAPCOM And we want to add an Ascension pass AOS, an

Well, I just let it be said that that was 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 51:00 CST 24:25 MC 49/3 

quite a booster ride and when we get a chance a little later, 
I'll just tell you about it. 

CAP COM We're about ready to lose time here. You re 

looking great, guys, and we'll pick you up in Hawaii here shortly. 

SC Okay, we're looking at the deserts of 

Australia right now and again everything is good on board. 

CAPCOM Roger, pick you up at 1:172 4. 

SC Gotcha. 

PAO This is Apollo Control. We're coming up now 

one 1 hour after liftoff for Apollo 17. And as you heard CAP COM 
Robert Overmyer reporting to the crew that everything looks good 
including the Saturn 3rd stage. Apparently the indication we 
had of a possible battery problem in the instrument unit nothing 
more than a bad bit of telemetry there. When the booster engin- 
eer got a good hard look at the telemetry on this pass, he 
reported everything looked good. We are ready at this point to 
begin the post-launch press conference at Cape Kennedy and we'll 
switch to Cape Kennedy and stand by for that press conference 



PAO This is Apollo Control. 1 hour 25 minutes after 

lift off. During the postlaunch press conference at Cape Kennedy, 
we had a short aquisition with the crew through the Hawaian tracking 
station. During that period of conversation, and during that period 
of monitoring the systems on the spacecraft and the launch vehicle, 
we found that the situation was essentially unchanged. That is both 
vehicles now looking good; the spacecraft and the launch vehicle. 
And we're progressing toward a normal translunar injection. 1 hour 
46 minutes 50 seconds from now. The crew has discussed one unexplained 
series of events. It appears that when certain switches are cycled 
or moved on panel 2 which is the main panel in front of them, the 
center panel of the spacecraft, they're getting a master caution and 
warning signal. A light comes on - a tone comes on. This is to 
attract the crews attention that something may be wrong and the normal 
procedure is then to look at another matrix of lights which would 
zero them in on the problem. The light - the system or the subsystem 
or particular area being monitered, or which had the problem would 
light an individual light. However, when they go to this other matrix 
of lights, they find that none of them are lighted. This is leading 
the crew and the flight controllers here in mission control to believe 
that they are getting an SP signal to the master caution and 
warning, when in fact nothing is wrong. We don't have any further 
explanation for the problem at this point. We will continue to look 
at the data and particularly during the translunar coast, we think 
we'll get a good long time to look at things in detail and try to 
find out precisely what is happening. At this point however, the 
problem presents no concern and one of the more likely explanations - 
possible explanations that's been advanced is perhaps some contamination 
in some switches. We did accumulate some taped conversation during 
press conference with the crew. We will replay that for you 
and then stand by for acquisition of signal over the United States. 

Hello Earthlings. We're back with you.

lead us to believe that zero ppportunity will be required.

Hey, you just wouldn't believe, Bob the light you 
can see in the west right now. It must be absolutely clear. 

CAPCOM Roger, Jack. Sounds spectacular. Jack, people 

in the room here want to know if you've been down your checklist 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 1:25 CST 0100 MC 50/3 

SC Oh, we got that out of the way in about 5 minutes. 

Have we missed something? 

CAPCOM There's a different checklist we're talking 

ab o ut . 

SC (Laughter) If you're talking about the flightplan, 


CAPCOM Roger. 

SC What a waste. If I'm not mistaken we must be 

just south of Arizona now. Is that right? right Bob? 

CAP COM That looks real good. Yeah, you're over Mexico 

there and looks like you're oh - maybe a hundred miles south of 
the border there. 

sc Okay. I'm pretty sure I'm looking up into 

Phoenix-Tucson complex there. 

CAP COM Roger. Understand. 

sc Beautiful. (garble) Yeah, the west is always 

that way. I wish it was daylight so we could see Senora and that 
country. That's spectacular, I'll bet you. (garble)

the squeal that time. 

LAUNCH CNTL Am I still squealing, is this Houston. 

SC That's afirm, you're very loud, almost 

unreadable with the squeal. Al , why don't you give it the 
short count? 

CAPCOM Geno, don't change anything, we think 

it's a ground site situation here and just stand by. 

SC I believe it's in the VHF, Bob. 

SC Okay, Bob, I'm not sure exactly where 

we are, but I'm looking out to an awful lot of lights on 
the horizon out there at 12 o'clock and an awful lot of 
lightening in the clouds out there. 

LAUNCH CNTL Roger, we show you just about the 

middle of the Gulf, look out ahead and you're probably 
seeing the very tip of Florida there. 

sc It looks like almost the entire Florida 

peninsula has got lights all blinded in somewhere. 

CAPCOM How does my comm sound to you now, 

Gene ? 

SC Okay, give us a short count. 

CAP COM Roger, short count follows: Five, 

four, three, two, one. One, two, three, four, five, short 
count out. 

SC Bob, you're all right now. 

CAP COM Okay. And can you give us a feel for 

what the final weather was at the Cape at launch. 

LAUNCH CNTL Yeah, let me get that for you. The 

reason why we had that problem on the comm is we just 
handed over from Texas to MLA and you're going through 
MLA now and it's great and so we so we have a little 
problem with our Texas site. 

S C Ok ay . 

CAPCOM The television coverage had you all 

the way through staging very well in the S 2 ignition 
then and you went right behind a cloud for a while but they 
were tracking you pretty well.

CAPCOM They also cut in for about a half 

minute or so and showed a view of the crowd in the just the 
available light from the booster and it stood out pretty 

SC Okay, Bob, we're going right over

SC Okay, Bob, we have not had any for quite 

some time, I think, since the last time we talked to you about 
th em . 

CAPCOM Roger, I understand. We'll probably get a 

good workout on that after TLI and try and track it down a 
little mo re . 

SC Okay, but also, we have not really been doing 

much switching since the insertion checklist was complete, either. 

CAPCOM Roger, understand. Got you glued to the 

windows, I guess, huh? 

SC They are interesting, I'll say that. Well, 

I certainly am, Bob, and again there's a big - a continuous 
intermediate cloud deck, I think. It has patterns comparable to 
what I've seen on pictures of ice flows, (garble). Pack ice, 
I should say, pictures of pack ice in the Antartic. 

CAPCOM 17, Houston. We've got two questions con- 

cerning the master alarms. One, do you get the master alarm on 
the LEB also; and two, do you get the tone with the master 

SC We did get the tone. The master alarms were 

on both panel 1 and panel 3. I can't tell you about the LEB 
right now. Maybe Ron can. No, I didn't pay that much attention. 

CAP COM Okay. 

SC Hey, Bob, there was something interesting, I 

want to get around to tell you. The mission timer down in the 
LEB when Ron went down there to get things squared away, was about 
15 seconds or so behind all the other clocks. 

CAPCOM Roger, we'll copy that. 

SC Okay, an d w e re s et i t , re synched it, and it's 

been running okay. I don't know whether that's a clue to any- 
thing or not, but apparently it happened either during launch or 
somewhere before we got down there right after insertion. 

CAPCOM Okay, we're going to lose you here in about 

9 seconds. Your GO is looking great and we're working on it and 
if you get another ME V , will you check the LEB board? 

SC Yes sir, I sure will do, Bob. We'll see you. 

What's our next DOT? 

CAPCOM Stand by. Carnarvon at 2:25. 

SC Thank you. 

PAO This is Apollo Control. Apollo 17 now over 

the horizon from the Ascension site - will be reacquiring in 
about 25 minutes through Carnarvon. And, as you heard CAPCOM 
Robert Overmyer advising the crew, we've been getting a good 
look at all the data, and spacecraft launch vehicles look fine- 
No discernable problems. Gene Cernan did mention one anomaly 
and that was the mission timer. One of the — one of the numerous 
clocks aboard the spacecraft which was running about 15 minutes 
slow - and someone said it appeared that it happened either dur- 
ing the launch phase or shortly before they got down to take a 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 155 CST 0130 MC 53/3 

look at it in the lower equipment bay. No explanation for that 
one at this point. And we show now 1 minute - 1 hour, rather - 
11 minutes until ignition for the translunar injection maneuver, 
the burn with the Saturn 3rd stage which will place Apollo 17 on 
its trajectory toward the Moon. Ignition time and still holding 
at about 3 hours 12 minutes 35 seconds ground elapsed time, and 
that burn will be about 5 minutes 45 seconds in duration, but 
we don't have the final calculated time from the flight dynamics 
officer which will undoubtedly vary somewhat from the premission 
flight plan time. At 2 hours 2 minutes this is Apollo Control 
H o us t on . 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 0200 GET 2:25 MC 54/1 

PAO This is Apollo Control, 2 hours 25 minutes. 

Apollo 17 now approaching the west coast of Australia. And we'll be 
reacquiring the spacecraft in about 35 seconds. During this pass over 
Carnarvon we expect to pass up the first set of numbers to the 
crew that they'll use in the translunar injection burn to put them 
on their trajectory toward the Moon. That maneuver is scheduled to 
begin at 47 minutes from now. And we have acquisition of signal a 
little bit early. 

CAPCOM 17, Houston. How are you going?

CAP COM Roger, good show. Are you saying that you didn't 

have any weather over that southern Africa there? 

sc N °t very much. Barely broken clouds in some 

places. Most of the countryside was clear. 

CAPCOM Roger. 

SC There were patterns like I haven't even seen in 

text books. Maybe I haven't been looking enough but some of the 
dessert and grassland patterns were - had the appearance of ice crystals

Carnarvon, and we've passed up the numbers to the crew they'll use 
in the translunar injection maneuver. The burn is targeted to 
last 5 minutes 51 seconds with a change in velocity of some 
10 359 feet per second. Accelerating Apollo 17 to the required 
speed to get it into an orbir. that will intercept the Moon 
And the time of ignition, 3 hundred 3 hours 12 minutes 
and we're showing an ejection time of 4 hours 39 minutes. The 
transposition and docking maneuver which preceeds ejection, is 
somewhat fluid in that it's done when the crew and miss ion ' con t ro 1 
are ready following translunar injection. However, from the 
projected time for ejection, it would appear that transposition 
and docking will occur about 25 to 30 minutes ahead of the nominal 
flight plan time. And we're now 39 minutes away from the scheduled 
ignition for translunar injection. At 2 hours 34 minutes this is 
Apollo Control, Houston.

Apollo 17 through Hawaii. During this Hawaian pass we're 
getting another good look at spacecraft and launch vehicle 
systems. The last look we had through Carnarvon everything 
looked very good. Flight Director, Gene Kranz, going over the 
status for these flight controllers observed that there 
appeared to be no problems that would interfere with TLI and 
we expect to have a normal translunar injection, about 23

the Apollo Range instrumented aircraft. We'll be picking up through 
Ascension shortly, at which time we'd expect the communications to 
improve, the noise to drop off. From Gene Ce rn an ' s report, also 
from the reports from Ron Evans, it appeared that that translunar injec- 
tion was extremely close to nominal. The crew read a cut off time of 
5 minutes 52 seconds. The premaneuver prediction was 5 minutes 
51 seconds. And the cutoff velocity appeared to be very, very close 
to the planned normal. Booster engineer, Frank Van Rosilier reports 
the booster cutoff appeared to be exactly normal. And booster 
engineer now predicting that the maneuver to separation attitude 
will begin in about 3 hours 33 minutes 27 seconds.

APOLLO 17 MISSION COMMENTARY 12/7/72 0306 CST 3:30 GET MC-59/1 

PAO This is Apollo Control at 3 hours 

30 minutes. The flight dynamics officer has just reported 
that initial tracking, following the translunar injection 
burn, shows the spacecraft to be on a very nominal trajectory, 
and a relatively small midcourse correction indicated at 
this time. The pre-burn prediction on that first midcourse 
correction was around 5 feet per second and we expect that 
that will be updated as we get additional tracking following 
the burn. In about 3 minutes the spacecraft should - the 
launch vehicle should be - begin maneuvering to the proper 
attitude for separation and we're predicting separation 
to occur at about 3 hours A3 minutes - or about 13 minutes 
f r om n ow . 

SC Frame 65 for the LNPS mag, November, 

N o vemb er . 

PAO About 10 seconds now until the Saturn 

third stage begins maneuvering into the proper separation 
attitude. And booster engineer reports from telemetry data 
that the booster has begun maneuvering into the proper 
attitude for spacecraft separation. 

SC Okay, we are maneuvering, Houston. 

CAPCOM Roger, we're watching it. 

sc Now we've got a few very bright particles 

or fragments or something that go drifting by in the maneuvers. 
CAPCOM Roger, understand. 

SC There's a whole bunch of big ones on my 

window, - just bright - it looks like the 4th of July on 
Ron ' s w in dow . 

SC Yeah, now you can see some of them have 

shape. They're very jagged, angular fragments and they're

CAPCOM Roger, look like fluid of some sort? 

SC Not to me, they look like pieces of 

something . 

CAP COM Roger. 

SC They're very bright. 

CAPCOM Jack, we'd OMNI copy Charlie. 

SC Bob, for the most part, these fragments 

are not - or are tumbling at a very slow rate. I tried a 
couple of pictures of them, different settings, you may get 
an idea of what at least, the patterns look like. 

CAPCOM Roger, I've got you. We're all ears 

on these fragments. Do you think you can figure out what 
they mi gh t be? 

SC Well, you know - I don't know - there 

are a number of possibilities. If you had some kind of a

bit as if they might be a - off the side of the S-IVB - and 
that's a wild guess -

This is Apollo Control at 4 hours 12 minutes. 
The crew aboard Apollo 17 at this time pressing ahead with their 
preparations for separating the lunar module and command module, 
now docked together from the Saturn third stage. You heard some 
conversation earlier about an indication that all of the docking 
latches have not locked up. Now there are 12 of these latches 
in the docking mechanism, 6 of which are instrumented, and of the 
6 that are instrumented, there was an indication that one of those 
may not have latched. However, we are confident that more than 
enough latches have locked up to assure a good solid dock, and 

the crew is pressing ahead with their preparations

CAPCOM Roger, we copy. That's good. 

PAO This is Apollo Control at 4 hours 30 

minutes. About 9 minutes from now the crew will be firing 
the pyrotechnic charges that separate the lunar module 
docked to the command module from the Saturn third stage, 
and springs will push the LM CSM back away from the launch 
vehicle at a rate of about 1 foot per second, and at ground 
elapsed time of 4 hours 52 minutes the launch vehicle will 
yaw to the proper attitude for an evasive manuever of about 
10 feet per second to be performed at a ground elapsed time 
of about 5 hours 3 minutes. This will increase the separa- 
tion difference to assure no chance of recontact between 
the booster and the spacecraft on route to the Moon. On 
removing the hatch between the LM, the CSM, allowing the 
crew to get a look inside the docking tunnel, they found 
that 3 of the 12 latches had not locked up, but on manually 
recocking them and activating them, they latched up properly, 
which indicates that there's nothing physically wrong with 
the system. We would expect that the next time the 2 vehicles 
come together to dock that the latches will function properly. 

Pretty good (garble) service.

APOLLO 17 MISSION COMMENTARY, 12/7/72, CST 4:46 GET 5:10 69/1 

CAPCOM Sounds like a winner, Gene. 

S C Ok ay . 

SC I guess you saw that one, Houston. That had no 

caution or warning with it. 

CAPCOM Roger, that master alarm? 

SC Yes , sir. 

CAP COM How about the LEB? 

SC (Garble) Ha. You caught me. I forgot to look. 

Keep after us, we'll get you that data for you. 
CAPCOM Roger, Jack. 

SC Gene's got his hands all over panel 2, which probably 

would have caused it. 

CAPCOM Jack, we think that might have been a real one, 

due to the accumulator cycle with the 02 makeup flow going on there, 
held the 02 flow little higher for a - greater than 16 seconds. 

SC Well, that's certainly a possibility. We didn't 

notice it looked upright at the time. But it- - sure that was the 
right time. 

CAPCOM Well, we're kindly watching it here and (garble) 

feels it is. 

SC Gee, I can't argue with him. 

SC Okay, Houston, ready to deactivate the primary 

evaporator if you concur. 

CAPCOM Roger. Jack we concur. 

SC Okay, Bob. VH F simplex, ALFA' s off. 

CAPCOM Roger. 

SC And we're gradually moving in to getting out of 

th e s uit s . 

CAPCOM Yeah, I bet you're looking forward to that. 

SC Well, I'll tell you it's a different world without 

that old 1-G on you. The old suit's a little bit friendlier. 

SC And, as you may have noticed, Bob, we've come to 

the end of the launch checklist. 

CAPCOM That's affirmative, and we've put ours away for 

posterity. We also started with our TLI zero data that we worked 
so hard to generate. 

SC Well, I'm just happy - didn't - use it. That 

view of the earth for a rev there was something I was looking forward 
to and was not disappointed. 

CAP COM That's great, Jack. 

SC Bob, you've got a pretty good size storm over the 

north. I guess the northwestern coast of India, where It starts to 
wrap up around to the west. It's around out on the horizon, so I 
can't make out exactly where it is too well. 

CAPCOM Roger. 

CAPCOM Could we get a readout on the LM , CM Delta P? 

SC Plus .4. 

CAPCOM Roger, we copy that. 

SC Bob, Antarctica is what I would call effectively 

just a solid white cap down on the - 


APOLLO 17 MISSION COMMENTARY 12/7/72 5:20 GET 04:56 CST 70/1 

SC White cap down on the South Pole. There's 

definite contact between the continent and the water, but as 
Ron said most of the clouds seem to be very artistic, very pic- 
turesque, some in clockwise rotating fashion but appear to be 
very thin when you can for the most part kind of see through 
those clouds the blue water below. 

CAPCOM Roger. 

SC The continent itself is the same color as 

the clouds but of course, more dense in a striking difference 
than any of the other white background around, because you can 
definitely see that contact with the water and with the clouds 
over the water. 

CAP COM Rog, understand. There'll be a comm switch 

over to Madrid here shortly, may break lock here in a few 
minutes here. Or a few seconds, really. 

CAPCOM And you might watch your accumulator's going 

to cycle in about 20 seconds here, see what happen with the master 

CAPCOM 17, Houston, how do you read through Madrid? 

S C You're loud and clear, Bob, and could you give 

us our distance from the Earth? 

CAP COM Rog, I'm looking at the board, I'd guess at 

about 19 000 miles, want me to get it exact? 

SC Just approximate ' s good enough. 

CAPCOM 18 100, Fido says. 

SC Okay, and I suppose we're seeing as 100 per- 

cent full Earth as we'll ever see, certainly as I've ever seen, 
it appears to be - it may be a little bit - a little bit of a 
terminator, way out to the well to the East out beyond Australia 
and beyond India, but beyond that it's about 99 percent pure. 

SC Bob, it's these kind of views - these kind of 

views that stick with you forever. 

CAPCOM Roger, Gene. 

SC We've got a I guess probably the continent 

of Africa dominates the world right now, it's covering oh the 
upper third - upper western third of the world. We can see the 
Sinai, we can see up into the Mediterranean, we can see across 
the Mediterranean although we can't quite make out the countries 
up there, we can see across into India. I can catch a glimpse of 
Australia out in the far horizon. Got Zanzibar on the southern 
tip of Africa, the cape down there just almost directly below us. 
And, I don't know exactly how bit Antarctica is but I guess we 
can certainly see more than 50 percent of it. And - the rest 
of it is all ocean. The Indian Ocean out into the Pacific Ocean 
back into the Atlantic Ocean and for the most part relatively 
clear of clouds except in the Antarctica region, and up towards 
Europe which is - which is on the horizon, across the Mediterranean 
It looks like there might be some clouds back up in that way. I 
Probably - probably - well not probably I can make out the entire 
coast of Africa from Mediterranean around to the west on back to 
the south back where it takes it's big dip to the east, back 
around the cape, back around up through the Suez Canal; almost 
p e r f e ct ly . 

CAP COM Roger, we understand. 

APOLLO 17 MISSION COMMENTARY 12/7/72 5:20 GET 04:56 CST 70/2 

SC And there's one batch of clouds that in 

northern Africa, just a small batch, it looks like it may be 
up near the - well no it's not near the mouth of the Nile it's 
quite a bit west of that, as a matter of fact, I can see the 
mouth of the Nile, I can see it running straight down towards 
us as it parallels the Suez and then sort of fades out into the 
central darker brown or darker green portions of Africa. 

CAPCOM Roger, Gene. Sure would be nice to have 

that on TV wouldn't it? 

SC Oh, I'd love to give it to you, any way I 

could . 

SC You know, there's no strings holding it up 

either, it's out there all by itself. 

CAPCOM Roger. I just was going through the 17 

status report on the CSM systems and boy everything is absolutely 
nominal with the exception of as glitching master alarm that 
we're trying to still track down but every other system is just 
nominal, everything is great. 

sc Okay, sounds good, that's the way they built 

i t f o r us . 

CAPCOM Gene, looking at our plot board, you're 

directly over the southern tip of Africa, or just slightly out 
in the Indian Ocean there according to our plot board which isn't 
exactly accurate at all times. But shortly you're gonna start 
going backwards on the Earth here and head back across the 
Atlantic, that ought to be some sort of a first; you cross the 
Atlantic twice, going from west to east, and now you're going 
to cross it going from east to west here shortly. All in a very 
short span of time. 

sc Yeah, I guess that does sound like a first. 


APOLLO 17 MISSION COMMENTARY, 12/7/72, CST 5:06, GET 5:30, 71/1 

PAO This is Apollo Control at 5 hours 30 minutes 

ground elapsed time. The white team of flight controllers, headed 
by Gene Krantz, is in the process now, of handing over to the team 
headed by flight director Pete Frank. After 12 hours, the team 
came on about 3 hours prior to the scheduled launch time of 8:53 PM 
Central Standard Time. Of course, launch occurred 2 hours 40 minutes 
late at a ground elapsed time of 11, - of a Central Standard Time 
rather, 11: 33 PM. As a result of the late launch-time the trans- 
lunar injection, that's up through translunar injection, also 
slipped 2 hours, 40 minutes. We would expect that the translunar 
injection which is targeted to make up the difference will get us 
back on the nominal flight plan time by the time the spacecraft 
arrives at the Moon. In other words, arrival time at the Moon 
would be at the same Central Standard Time as called for in the 
Flight Plan at about 1:49 PM Central Standard Time, December 10. 
But, the Ground Elapsed Time would be about 2 hours, 40 minutes 
earlier than that provided for in the Flight Plan, the arrival 
being at about 86 hours, 14 minutes ground elapsed time. The 
2 hour, 40 minute difference being accounted for in a speedier 
arrival time at the Moon, a translunar injection burn being targeted 
just slightly longer than would have been the case in a normal 
launch. The spacecraft getting to the Moon in a total elapsed 
time 2 hours 40 minutes less, in effect, making up for lost time 
from the late launch. In order to get the flight plan back in 
agreement with the ground elapsed time the GET, or ground elapsed 
clock, will simply be moved ahead 2 hours, 40 minutes between now 
and the time spacecraft arrives at the Moon. So, that by the time 
Apollo 17 is inserted into Lunar Orbit, the GET will once again 
agree with the flight plan GET and of course, the Central Standard 
Time of arrival will be the same as was originally planned by 
virtue of a speedier trip time. As a result of the late liftoff 
it was not possible to program television coverage of the trans- 
position and docking. This was because of a shift in the 
orbital ground track moving the ground track away from the needed 
Manned Spaceflight network coverage for television. We simply 
didn't have an adequate ground station to receive the television 
signal from the spacecraft. There has been one recurring problem 
that is yet unexplained. That is in the displays and control 
system. The crew reported on several occassions that master 
alarm was occurring. The master alarm manifests itself in a form 
of a light that flashes in the Command Module. There are three 
of these lights and also a tone that comes on and a normal procedure 
is when the master alarm light comes on and the tone sounds, the 
crew then looks at another matrix of lights to determine precisely 
where the problem is. However, when looking at this matrix of 
lights none of them were lighted, indicating that some spurrious 
signal had ignited or lighted the master alarm light and that 
there was In fact no problem in the systems. There is at this 
point no explanation for the problem. However, engineers here in 

APOLLO 17 MISSION COMMENTARY, 12/7/72, CST 5:06, GET 5:30, MC-71/2 

the Control Center, are looking into the past history of panel 2, 
which is the panel on which a number of switches are located, 
which have triggered this master alarm to see if there is a 
history of panel 2 that would indicate a possibility of some 
momentary short in the caution and warning system, which could 
give a master alarm. Apollo at this point is an annoyance, but 
does not appear to be a serious problem. All other spacecraft 
systems are performing normally, and the trajectory to the Moon 
is almost precisely as planned at this point. We do not antici- 
pate a change of shift press briefing. The white team will 
be coming back on at the regualar Central Standard Time 4:00 PM 
tomorrow. And in light of this rather short turn around we re 
going to forego the change of shift press briefing. At 5 hours, 
36 minutes this is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/7/72 05:14 CST 5:38 GET MC72/1 

SC Bob, this is Jack here. We've got a 

UCTA dump scheduled, is possible at 6 o'clock. There's 
nothing secret about that time is there? 

CAPCOM Nothing at all. When ever you are 

ready, just go ahead and dump. 

SC Okay. 

SC Bob, one of the things that we miss in 

our training is a good geography lesson and particularly 
on Anarticia. I got the binocular out and apparently the 
dark band that Gene - Ron mentioned and interfaced between 
the intercontinental water is that between the pack ice and 
the water and you can - by very subtle changes in the various 
movements of the ground probably make out where the actual 
continent begins and the pack ice ends. There are a few 
exposed ranges. I guess it's mid summer down there now and 
you can make out the snow free areas scattered at least in 
the northern portion of the continent. 

CAPCOM Rog, Did you get any pictures of that, 


SC Oh yes. We got some pictures earlier. 

I'm going to get another one here in a minute. I'll tell 
you, if there ever was a fragile appearing piece of blue 

the Earth right now. 
Roge r . 

There, we got a master alarm. 
Okay, we copy that. 
And there's one in the LEB. 
Okay, good data point. 
And there are no caution lights. 
It came right at an accumulator cycle 
high 02 flow again. 

Yes, I just checked the time and I think 
on that one. But we gave you your LEB data

p oin t . 



parti cularily 


the binoculars, 
think I can see 

Yes, sir. 

The problem with looking at the Earth - 
Anarticia, is that it is too bright. 
I understand. 

And so I'm using my sunglasses through 
which is not the best viewing platform. I 
some of the areas of the Dry Valley but 

again I'm not too sure of my geography, Bob. There are 
clouds over the continent, I believe. But, of course, they 
are just as white as the snow and you only see differences 
in texture brought out by - probably by varying photometric 
return because of fairly low sun angles down there. 

APOLLO 17 MISSION COMMENTARY 12/7/72 05:14 CST 5:38 GET MC72/2 

CAPCOM Roger. 

SC But you can see patterns of, what I 

believe is, pack ice leading off from that sharp interface 
that was talked about earlier. And those patterns seem to 
merge directly with the patterns of the clouds as if the - 
at least near the continent - the oceananic currents are 
controlling the air currents up to a point along with the 
movement of the pack ice. 

CAP COM Roger. 

SC E'm distinguishing the pack ice from 

clouds mainly by the angularity of the patterns within 
them. There is no good clear color or albedo distinction. 
So, I could be looking entirely at clouds but I suspect 
there are some pack ice patterns too. I'm not keeping you 
awake, am I, Bob? 

CAPCOM No sir. Just keep talking. We're 

listening. I'm sure not much of the world is listening but 
this will all be recorded and you can read it all when you 
get back. And think it through and tie it up with the 

and I'm sure there's going to be people interested

be asking you some better questions. Right 
now, I can't think of any to ask you. 

SC Well I can't - I really wish I knew 

geography. I don't know - I wish I'd thought of bringing 
a good map of Anartica. Could somebody do a little 
researching for me and see if they could tell me if we're 
to have a little American view - say on the eastern edge 
of the continent?

APOLLO 17 MISSION COMMENTARY 12/7/72 04:14 CST 5:38 GET MC72/3 

SC Okay. There is a good strong northern 

hemisphere cyclone up near India. And I think Gene mentioned 
that. It, I think, was one I saw in some of the forecast 
sheets as a dissipating hurricane or typhoon. I'm not sure 
which it is there. I guess it is a typhoon. And I see 
something here that I noticed in Earth orbit, Bob. That 
as you approach the terminator - now I'm looking at the 
Eastern terminator. Have to keep all my directions straight 
here. Yes, eastern terminator. The clouds - those associated 
with the cyclone over India and one that's - appears to be 
due south of there maybe 30 degrees of latitude have a gray 
appearance. Instead of the brilliant white of other clouds. 
As you approach the terminator those - at least the high 
level clouds are gray. Now, when we were going over them 
in orbit the lower level clouds were still white and I think 
I can see a head of that right now. That sun gives a strong 
light reflection off of the •- 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 5:37 GET 5:56 73/1 

SC The sun gives a strong light reflection 

off of the buildup in the low level clouds, whereas the 
high level and normally layered appearance, and maybe 
some of the intermediate level stratus get to look gray, 
because of grazing sun I suspect. 

CAPCOM Roger. You mentioned several things 

on this orbit that kind of Intrigued me, you mentioned 
seeing the rainbow, and we were trying to figure out how 
you saw a rainbow up there, and you were in orbit already 
at that time. Do you remember that? 

SC Well, we were speaking of the merits 

of th e s unri s e . 

CAP COM Okay that's - 

SC That's having a banded color appearance 

that varied as you approached the sunrise. I can't remember 
what we - I think we put some of that on tape, we were 
probably LOS at the time, but the banded character of the 
sunrise in the atmosphere was very very marked. There was 
a gray-blue upper layer that merged or graded into a bril- 
liant blue intermediate zone that was just above the cloud 
level and within the clouds, you got an orange to yellow 
band getting more yellow as the sun rose, that was broken 
by the dark patterns of the buildup. 

CAPCOM Roger. Good show. 

SC The interesting thing was the continual 

glow on the horizon, we had even at night. On the darkside 
pass, and that glow was in the atmosphere because I could 
see stars rise over the horizon in It and then pass on 
through i t . 

CAP COM Roger. You were talking, the air glow 

low I guess is the phenomenon most interesting thing before 
Kind of interesting. 

SC Yes, that's right, it's I guess standard 

air glow, but it is very striking and it's a continuous 
thing even in the dark pass. 

CAPCOM Roger. 

SC I think I did see the eastern tip of 

South America now. 

CAP COM Roger, you're starting to backup now, 

coming the other way, so you're still over Africa according 
to our chart here, but you're backing up towards South 
Ame r i ca . 

SC Yes, I can see the part on South 

America that mercator thought that fit in with the bend 
in Africa some many decades ago and started people thinking 
about moving continents around on the crust. 

CAP COM Roger. Jack, how'd the PGA doffing 

go? Are you all out of the PGA' s now? 

SC That's been worked. We're taking it 

slow and easy up here, Bob. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 5:32 GET 5:56 73/2 

CAPCOM Roger, understand. 

SC I'll just be curious to see if they all 

fit in th at bag . 

SC I think you'll find that Ronald Evans 

will also be curious about that. He's already made comments 

CAPCOM Roger. 

PAO This is Apollo Control at 6 hours. As 

Jack Schmitt gives the description of the earth, Apollo 17 
is 22 868 nautical miles from earth velocity 12 520 feet per 
s e con d . 

SC We certainly do have a very clear 

intuitive Impression although the evidence is hard to put 
together that the frontal drifts that move off the Anarctic 
continent do not take on any well defined characters until 
they get into the moist regions of the ocean, and when they 
do they seem to pick up an - 


APOLLO 17 MISSION COMMENTARY 12/7/72 06:00 GET 05:36 CST 74/1 

SC - character until they get into the voice 

regions of the ocean and when they do, they seem to pick up 
an arculate circulation that in the view we have seem to get 
fairly spaced cyclones patterns that lie between the Cape of 
Good Hope and northern portion of Anarctica and these certain 
circulations of cyclones follows roughly an east/west pattern 
and the curve - the arcs of the fronts are more north/south 
than let's say northwest swinging around to the south. 

c APC0M Roger. 

SC All of them - all of them very nicely defined 

as southern hemisphere cyclones. There are about 4 of those 
v ^sible swinging around oh I guess that's latitude I'm having to

of Africa there is about 32

South . 

SC Well, that sounds like a pretty good guess. 

It look like the intertropical convergence zone over Africa is 
starting to get more and more clouds in it now. I suspect as 
midday approaches, wh i ch is what we're seeing there, we can 
expect to see more and more moisture indications. 

CAPCOM Rog, they're probably about noontime right 

there right now, it's 11:36 at the zero meridian at Greenwich so 
it's just a little bit before noon right in that area you're 
talking about. 

SC Yeah, some of those masses of what I suspect 

are cumulus build ups , well not really, they don't look they're 
as concentrated and localized. More like just masses of fairly 
dense clouds that are developing in that band of green, that 
the lower portion of Africa. 
Ro ge r . 

Stay tuned for the next installment on the 
try and get out of this suit.

cabin or springs mechanics here in zero-g; there's always 
something going on. 

CAPCOM Roger. 

PA0 This is Apollo Control at 6 hours 7 minutes 

No midcourse correction number 1 will be performed. The value 
of the maneuver that would be required is less than 3 feet per 
second and midcourse correction number 1 will not be performed 
by Apollo 17. The spacecraft is now 23 6 82 nautical miles from 

APOLLO 17 MISSION COMMENTARY 12/7/72 06:00 GET 05:36 CST 74/2 

PAO Earth, velocity 12 301 feet per second. 

SC Bob, if I'm not waking you up an observer 

from another planet certainly - probably could decide that we 
have such things as clouds at least large thunder storms because 
right at the terminator you get a brightening of the Sun lit 
side and a long, long shadow out to the out to the east that is 
reminiscent of what we saw in the early days looking at the Moon 
at the terminator. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 5:46 GET 6:10 75/1 

SC That is reminiscent ofwhatwesaw in 

the early days looking at the Moon at the terminator. 
CAPCOM Roger. 

SC However, in the next pass around, I'll 

bet you wouldn't see them. 

SC I've never been a big - well, I didn't grow 

up with the idea of drifting continents and sea floor spreadings, 
but I tell you, when you look at the way the pieces of the 
northeastern portion of the African continent seem to fit 
together separated by a narrow gulf, you could almost make 
a believer of anybody. 

CAP COM Roger, it's beginning to look like the 

globe that you might buy down at the store, huh? 

SC Oh, I don't think so Bob. 


SC I don't think we'd better put this one 

up for sale. Somewhere there might be somebody that would 
like to b uy it. 

CAPCOM Say, Jack. We noticed the 02 flow has 

dropped down now. We're wondering, did you all close the 
waste storage vent valve. 

SC I d on ' t t'h in k so, let me check on that. 

It might have gotten closed inadvertently in the game we 
were playing down in the LAB. 

SC Ron says it's still on vent. 

CAPCOM It's on vent, Roger. 

CAPCOM Okay, we're noticing that the flow is 

coming back up slowly so something caused it to drop, and 
it's coming back up. 

SC Okay. 

CAPCOM 17, Houston. 

SC Go ahead. 

CAPCOM Jack, just to ease those words I said 

before, we looked at the schematics here a second and 
you've been dumping urine out of that same line as that 
waste vent, and that would probably cause the pressure 
to build up enough to slow the 02 flow, and we notice that 
the 02 flow is climbing back up to where it belongs. 

SC Well, that's clever. Okay. 

CAPCOM Didn't mean to worry you there, 

shouldn't have said it, I guess before we looked at the 
s chemati cs . 

SC Oh, I really hadn't started to worry 

about it yet, Bob, so no sweat. 


APOLLO 17 MISSION COMMENTARY, 12/1/12, CST 5:06, GET 5:30, MC-75A/1 

SC Bob, I can assume that from what you said 

there will probably not be a midcourse 1. 

CAPCOM That's exactly what we're working towards, Gene. 

And I'm sorry I didn't convey that feeling to you a little earlier. 
There's no reason for midcourse 1 right now, 

SC Okay, because we prefer to press on and get 

the suits off and hit the sack, rather than making them, unless 
we have to. 

CAP COM That's for sure. Roger. The earlier data 

showed us midcourse 1 would have been less on 3 feet per second 
and we wouldn't have done it. And the data's been fluctuating. And 
they're smoothing it: out and it's still holding that way, so we 
won't be doing it probably. 

SC Okay. Very good. 

SC Bob, I'm looking over Gene's shoulder here at 

the Earth and it must be an awful clear day for the so called 
convergence zone across Africa. Gene I think indicated that when 
we crossed it earlier, most of Africa is clear. Only some, probably 
broken, scattered clouds cumulus in the east central portion that 
are running on the lines of north south lines. 

CAPCOM Roger. 

SC Looks like a major circulation system off the 

southern tip of Africa as Gene mentioned, plus one west of that, 
20 or 30 degrees of longitude. Make that east of that. 

CAPCOM Roger. 

SC And, southwest of - make that south, southwest 

of the tip of Africa at Cape Good Hope, there looks like an insi- 
pient circulation system developing about half way between the 
Coast of Anartica and Africa. If I had to guess, It's going to 
swing up north toward the Cape and then swing west. The whole 
pattern, looks like now a fairly equally spaced cyclones that are 
sort of circling aroung the Anartic continent and we can see it now. 

CAPCOM Roger, Jack. 

SC I would guess that South Africa is going to 

have good weather for several more days at least. And if the 
pattern is apparent the clouds we see are correct the last 
disturbance I mentioned probably is going to pass down to the 
Cape also. 

CAPCOM Roger. Understand. 

SC As we were going over our daylight around the 

earth in our orbit, it was very clear looking at the various clouds, 
Bob, what were high clouds and what were low clouds, particularly 
when you have them together. High clouds carry very distinct 
shadow patterns on the lower ones and very commonly had entirely

to be more associated with (garble) front patterns, whereas, the

Okay . 

That ought to be interesting. 

This is Apollo Control at 6 hours 24 minutes, 
that was just being discussed was performed 
propulsion system; just completed Delta V of 
to tune up the trajectory for S-IVB impact at 
the desired location on the lunar surface of 7 degrees south, 
8 degrees west. That's approximately 200 kilometers of the 
Apollo 14 ALSEP site where the seismometer is located. That im- 
pact is expected to be picked up by the other seismometers on 
the Moon, the other Apollo lunar surface experiment seismometers. 
Booster systems engineer is now maneuvering the S-IVB stage, the 
third stage of the launch vehicle to a solar heat control attitude. 
This is to minimize the heat into the instrument unit. They will 
then track the stage for a considerable length of time and determine 
whether another corrective burn will be required. At 6 hours 
25 minutes into the mission, this is Mission Control, Houston. 

PAO This is Apollo Control at 6 hours 27 minutes. 

Booster systems engineer has just reported to the Flight Director 
that the S-IVB stage is in good shape, with 14 hours life time 
remaining. The limiting factor on the S-IVB is the battery life. 
Fourteen hours of battery life remaining on the S-IVB.

SC Well, the main A interval - I just 

happened to be looking at the panel and the main A interval 
light flicked on for a second. And of course, obviously, 
main A is up now.

at present on the normal GET of the flight plan, normal ground 
elapsed time. Under that schedule the crews rest period will 
begin about 9 hours and 15 minutes into the mission. If, how- 
ever, the crew completes the activities that are scheduled in 
the flight plan early the rest period will probably begin early 
if they so desire. However, at the present time we are continuing 
to operate on the GET of the flight plan. At 6 hours 50 minutes, 
this is Mission Control, Houston.

CAP COM Rog. We've been discussing the question of 

what your frequency is going to be in terms of headset or not with 
reference to all of these various master alarms, and I guess we'd 
feel better if one of you guys slept with his headset on. We were 
curious as to what your plans are. 

SC Bob, since I've got to wear the bio net 

anyway, I might just as well go ahead and keep it on. 

CAP COM Okay, the other option is for us, if we're 

trying to get hold of you is to put the klaxon on but we're a 
little un in favor of that because of the possibility one of these 
spurious things waking everybody up that way. 

SC Yeah, I'll go ahead and keep it on and see 

how that works out, for a while. 

CAPCOM Okay, we copy that. And, when you guys are 

ready we have a couple of - we have 3 items to read up to you 
for the updates of the flight plan.

CAPCOM Jack, I guess that - we're not sure 

what you said or meant there or what. In the flight 
plan, itself, we want H2 heaters and 1 and 2 to AUTO and 
we want H2 fans on tank 3 only, AUTO. There - 3 there 
for H2 tank 3. 

SC Okay, you're teaching me to read 

carefully early, aren't you? 

CAP COM We're trying. The 1 and 2 heaters will 

be on AUTO and 3 fan will be on AUTO. 

SC That's the way it is now and consider 

the fans have been cycled. 

CAPCOM Roger. 

SC According to the checklist. 

SC You might look at the third line on 

1-29 and look at the H2 line on the flight plan and see 
why I was confused. 

CAPCOM Roger. We were just discussing whether 

or not there was a fan or fans in each tank. 

SC That ought to keep you awake this

SC What I was really trying to do, Bob, 

was getting out. of chlorinating the portable water but you 
wouldn't bite. 

PAO This is Apollo Control at 8 hours

32 nautical miles from Earth; velocity 9 thousand 6 hundred 
67 feet per second. Apollo 17 crew in the period now in 
the flight plan where they're making preparations for their 
rest period. Getting the systems in the proper configuration 
for a sleep period. The spacecraft has been maneuvered to 
the passive thermal control or PTC mode - attitude, rather. 
And just prior to the rest period the crew will spin up the 
spacecraft for thermal control during the rest period. The 
spin rate will be slow or approximately 3 revolutions of 
the spacecraft per hour but it will keep the thermal balance 
on the spacecraft. At 8 hours 30 minutes, this is Mission 
Control, Houston. 

CAPCOM Apollo 17, Houston. Over, Jack. 

SC Go ahead. Over, Bob,. 

CAPCOM Okay. We're going to give you a little 

high-gain antenna practice here. We'd like to pick up with 
the high-gain antenna again so that we can get your PTC - 
watch your PTC develop. We'd like you to go to a pitch of 
40 and yaw of 2 75 on the high-gain. That's 40 pitch; 2 75 yaw;

don't we do it that way. 

S C Ok ay . 

CAP COM After you start the roll 17, we'd like to 

go back to omni bravo and stow the high gain. 
SC Okay 

CAPCOM We only need the high gain to keep a good 

check on your rates . 

CAPCOM And 17, that means stow the high gain after 

you - after the start up, we'd like to watch the start up itself.

Apollo 17 now, 41 6 77 nautical miles from Earth, velocity 9159 feet 
per second. The spacecraft has stabilized into a passive thermal- 
control mode now. It is completing one revolution every 18 minutes. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 8:50 GET 9:17 92/1 

PAO This is Apollo Control at 9 hours 26 min- 

utes. The Booster Systems Engineer has advised Flight Director 
Pete Frank that a second midcourse correction for the S-IVB, the 
third stage of the launch vehicle will be required. This 
maneuver is performed with the auxiliary propulsion system of 
the S-IVB, and the Booster Systems Engineer will command this 
burn at 11 hours 15 minutes ground elapsed time. The magnitude 
of the burn is not known at this time. That will be determined 
shortly before the midcourse is performed. The purpose is to 
tune up the trajectory to more precisely target the S-IVB stage 
to the desired impact point on the lunar surface. Tracking to 
this point of the spacecraft indicates that a midcourse cor- 
rection will probably be performed for the spacecraft at the 
scheduled midcourse number 2 time at 35 hours and 30 minutes. 
A preliminary look - that's a very early look shows it to be 
about 10-1/2 feet per second, but that will be refined as we 
get closer to the time. At 9 hours 27 minutes, this is Mission 
Control Houston.

We have had no voice communications with the crew for some time 
now. But we do have indications that they have not yet fully 
configured the spacecraft for their rest period. Normally the 
voice switch is turned off the last step before the rest period. 
That voice switch is still on. Apollo 17 now 43 261 nautical miles 
away from Earth, velocity 8964 feet per second. 


APOLLO 17 MISSION COMMENTARY 12/7/72 09:10 CST 9:37 GET MC94/1 

PA0 This is Apollo Control at 9 hours 48 minutes. 

From the data that he is receiving, the Flight Surgeon, Dr. Sam 
Pool, reports that he believes the spacecraft Commander Gene Cernan 
is asleep. Cernan is the only member of the crew who is wearing 
the biomedical harness during the rest period, and therefore, is 
the only one that the flight surgeon is getting measurements on. 
But the indications are that Cernan is asleep and apparently the 
entire crew has gone to sleep. Apollo 17 now 44 749 nautical 
miles from Earth. Velocity 8794 feet per second. The awake clock 
as operating in the Control Center shows wake up for the crew in 
5 hours 10 minutes 37 seconds. 

PA0 This is Apollo Control at 9 hours 59 minutes. 

The Flight Dynamics Officer, Bill Boone, has computed the half way 
marks for the spacecraft in both time and distance. We'll give 
those to you now. Apollo 17 will reach the half way point in 
distance at a ground elapsed time of 30 hours 3 minutes. Its 
distance from both the Moon and the Earth at that time will be 
114 787 nautical miles. Its velocity, referenced to the Earth, 
will be 4522 feet per second; referenced to the Moon, 3826 feet 
per second. The half way mark in time will be reached at a 
ground elapsed time of 43 hours 8 minutes 6 seconds. At that 
time Apollo 17 will be 144 924 miles from the Earth, with an 
Earth reference to velocity of 3551 feet per second. And it will 
be 87 561 nautical miles from the Moon, with a Moon referenced 
velocity of 3403 feet per second. Apollo 17 will cross the 
lunar sphere of influence at the ground elapsed time of 70 hours 
43 minutes 24 seconds, at which time it will be 190 725 nautical 
miles from the Moon. Earth referenced velocity 2 340 feet per 
second. Distance from the Moon at that time, 33 639 nautical 
miles, with the lunar referenced velocity of 3356 feet per second

Apollo 17 now, 48 070 nautical miles from Earth, velocity 8434 feet 
per sec on d. 

Pete Frank and the orange team of flight controllers getting 
ready to hand over to Jerry Griffin and his gold team of flight 
controllers at this time. Astronaut Bob Parker will remain as the 
CAPCOM for a good deal of this next shift. Several spurrious 
master alarms that were seen while the spacecraft was still in 
Earth orbit are as yet unexplained. There are no obvious reasons 
for them. The spacecraft experts in the back rooms, the support 
rooms here at the Mission Control Center are still tracking this 
situation. It's not considered a serious problem. The more 
recent master alarms that have occurred during this shift and 
during the translunar coast phase after Apollo 17 burned trans- 
lunar insertion, are attributed to a higher than normal oxygen 
flow at regular intervals in the cabin. The cabin is still 
being purged of the partial nitrogen atmosphere that it contained 
at launch that is being purged, a vent valve is open in the 
cabin and the higher than normal 02-rate has been introduced to 
help purge the cabin. Now, added to that when the water accumula- 
tor in the suit circuit cycles, there Is a brief increase of 
oxygen flow over and above the higher than normal flow that we 
are using to purge the cabin. And this is just high enough to 
when the water accumulators cycles it brings it up just high 
enough to trigger the master alarm. It is not a problem. The 
last three or four master alarms that we have seen are attributed 
to this. However, the Earth orbit master alarms are not yet 
accounted for. But, they are not considered to be a serious 
problem. During this shift a midcourse correction number 1 
was performed on the SIV-B stage of the launch vehicle, 13 feet 
per second performed with the auxilary propulsion system. 
A second midcourse for that third stage of launch vehicle is 
planned at a ground elapsed time of 11 hours 15 minutes. The 
magnitude of the burn is not: yet known. These midcourses are to 
tune up the trajectory of that stage, to bring it closer to the 
desired impact point on the lunar surface. As far as the 
spacecraft is concerned midcourse correction number 1 was passed. 
We did not perform midcourse correction number 1. The magnitude 
at that time was less than 3 feet per second. We will probably 
perform a midcourse correction number 2 at 35 hours and 30 minutes. 
A preliminary look at that indicates about a 10-1/2 foot per second 
burn at that time. The Mission is going well. We have not heard 
from the crew for some time now and are confident that they 
are asleep. The spacecraft is in passive thermal-control mode, 
stabilized in 1 revolution every 18 minutes, approximately 3 per 
hour. The crew is scheduled to be awakened 4 hours, 24 minutes 
from this time. At 10 hours 35 minutes into the Mission, this 
is Mission Control, Houston.. 


APOLLO 17 MISSION COMMENTARY 12/7/72 10:09 CST 10:36 GET MC96/1 

PAO This is Apollo Control at 11 hours 27 minutes 

ground elapsed time into the mission of Apollo 17. Approximately 
11 minutes ago, as you were 6 minutes ago, the S-IVB corrective 
burn was performed roughly 14.2 feet per second to modify the 
trajectory of the S-IVB third stage in the Saturn V, targeting 
for impact just west of the crater Ptolemaeus at latitude 7 degrees 
south by longitude 8 degrees west. However, the actual impact 
location and the time of impact will be forthcoming after some 
additional hours of tracking of the stage has been gathered. We're 
looking now at a midcourse correction burn number 2 of the Apollo 17 
spacecraft at 35 hours 30 minutes, with a change in velocity - 
a posigrade of 10.5 feet per second. Some 3-1/2 hours remaining 
in the crew rest period. All three apparently sound asleep at 
this time. And the passive thermal control mode puts the spacecraft 
at spinning at some 3 revolutions per hour. To repeat earlier 
statistics on half way in distance, time, and when the so-called 
sphere of influence is crossed will be at the half way point in 
distance at 30 hours and 3 minutes ground elapsed time, in which 
time it will be 114 787 nautical miles either direction to the 
Earth or Moon. And a half way point in time will occur at 43 hours 
8 minutes and 6 seconds when the spacecraft will be 144 924 nautical 
miles out from Earth; and 87 561 nautical miles out from the Moon. 
The so-called sphere crossing, or the point in which the spacecraft 
is assumed to come under the gravitational influence of the Moon, 
will take place at 70 hours 43 minutes 24 seconds when the space- 
craft is 33 6 39 nautical miles out from the Moon and approaching. 
The air/ground circuit has been up all of this time since the crew 
has retired for a fairly brief rest period, and at this time we 
will take down the air/ground circuit until the wakeup call is 
made some 3 hours 29 minutes from now. And at 11 hours 30 minutes 
ground elapsed time., this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 12:00 GET 12:27 97/1 

PAO This is Apollo Control at 12 hours 

27 minutes ground elapsed time into the mission of Apollo 17. 
And Apollo 17 at the present time is 56 948 nautical miles 
out from earth at a velocity of 7 609 feet per second. A 
short time ago the Booster Systems Engineer Frank Von Ren 
seler reported that after the final APS burn in the S-IVB 
stage, which is targeting the stage to impact on the Moon, 
he reported that the S-IVB stage was tumbling intentionally 
after that burn, and as he gathered up all his documents 
and packed his briefcase, on the flight directors loop, he 
said, "I've enjoyed working with you on the Apollo program." 
Flight Director Neil Hutchinson replied "It's been nice 
riding with you." The riding implication being that they 
were riding on his launch vehicle. Van Renseler is a 
Marshall Spaceflight Center Engineer detailed to the Flight 
Control Division here at Manned Spacecraft Center. Van 
Rensleser finished his job for the last time. He packed 
his launch vehicle documents and left the room. The 
booster systems console is vacant for the final time in 
Apollo. Some 2-1/2 hours remaining in the crew sleep 
period. No word from the crew. They have not talked to 
the ground nor vice versa in the last several hours and 
at 12 hours 29 minutes this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY, 12/7/72, CST 13:00, GET 13:27, MC-98/1 

PAO This is Apollo Control 13 hours, 27 minutes 

ground elapsed time into the Mission of Apollo 17. The spacecraft 
presently is 61 186 nautical miles out from the Earth, decelerating 
slightly in its velocity now 72 72 feet per second. Crew had another 
hour and a half of sleep period remaining. They will be awakened 
about 2:30 Central Time. This is a rather short sleep period 
slightly under six hours, the object being to get the crew back 
on to Houston time day-night cycle eventually. The cycle 
disturbed somewhat by the, - initially what would have been a 
night launch, and ended up being a morning launch, - early 
morning launch at least by Cape time. Got a hand over to the 
Goldstone 210-foot tracking antenna, about 8 minutes ago. Ai: d . 
that station at the present time is handling spacecraft data, and 
when the crew awakens will handle the voice transmissions between 
the Control Center and the Crew of Apollo 17. 

At 13 hours, 28 minutes ground elapsed time this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/7/72 14:00 CST 14:27 GET MC99/1 

PAO This is Apollo Control at 14 hours 

27 minutes ground elapsed time into the mission of Apollo 17, 
Slightly more than a half hour remaining until spacecraft 
communicator, Robert Parker, wakes the crew of Apollo 17 
up after a brief 6 hour rest period. Apollo 17 presently 
65 thousand 2 hundred 73 nautical miles out from earth; 
velocity now 6 thousand 9 hundred 74 feet per second. And 
getting back on schedule with Apollo 17 because of the late 
liftoff and the hold situation early this morning. The 
translunar injection burn was targeted to get the spacecraft 
at the moon or into lunar orbit at about the same actual 
time it would have had we launched on time - at 8:53 P.M. 
last night central time. However, to get the flight plan 
back on the actual indicated ground elapsed times shown in 
the flight plan at approximately 64 hours they're going to 
have what is called a GET update some two hours and 
40 minutes to force the event times in the flight plan to 
agree with actual ground elapsed times flown in the mission. 
We'll come up again in about a half hour as Parker makes 
his initial wake up call to the crew and at 14 hours 
29 minutes, this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/7/72 14:31 CST 14:57 GET MC100/1 

PAO This is Apollo Control 14 hours 

57 minutes ground elapsed time into the mission of 
Apollo 17. A 2 minutes mark remaining in the crew waken - 
wake period or sleep period before the crew is awaken. 
Spacecraft communicator, Bob Parker, should be calling 
them shortly and we'll stand by for that first wake up 
call. Rather slack day as far as crew activity today. 
After their post-sleep check list checking over the systems. 
The flight director just advised the CAPCOM to hold off on 
the wake call until they switch antennas. There's some 
P23 navigation sitings that will be run today and that 
apparently is about all the activity scheduled during the - 
this work period. However, there will be at 35 hours and 
30 minutes a midcourse correction number 2, which this time 
looks like about 10 and a half feet per second. Apollo 17 
now is 67 thousand 365 nautical miles out from the Earth; 
velocity 6 thousand 8 hundred 29 feet per second. Spacecraft 
communicator, Bob Parker, has been joined at the CAP COM 
console by backup Apollo 17 commander, John Young, and his 
relief CAPCOM, Gordon Fullerton. Standing by for the 
antenna arrangement to be sorted out. Spacecraft, at this 
time, is still in the barbeque roll or passive thermal 
control mode, three revolutions per hour to stabilize the 
temperatures on spacecraft systems. They'll open up the 
air-ground circuit for the first call when it does come. 
At 15 hours and 1 minute, this Apollo Control. 

CAPCOM Here we go. Apollo 17, Houston. 

Good morning . 

SC Hello, Robert. 

CAPCOM Glad to have you with us again. You 

guys got a good nights sleep, we think. 

SC Well, I'll tell you, it was looked 

forward to. 

SC Give us a few minutes here and we'll 

get operational. 

CAPCOM Ah, Roger. Give us a call when you 

are ready to talk to people,, 

SC Okay. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 14:39 GET 15:06 101/1 


there, it looks 
i de a . 

does it look kind 

From the looks of things, Bob, down 
like getting off last night was a good 

Gen o . 


Got a new Capcom now, 
of cloudy down there? 

Yes, hello Gordo, how you doing? Yes, 
I'm looking - oh we're probably directly over - just west 
of the Pacific, but the bottom third of South America I 
suppose, and I've got North America, Mexico and the U.S. 
on the top third - top 25 percent of the earth, and it 
looks like you've got cloud cover from somewhere where the 
coast bends around Corpus and north into the great lakes 
and completely out into the Atlantic and it could cover 
Florida (garbled). 

CAPCOM Roger. I can verify the part 

the Cape and Houston anyway. 

SC Yes, the Gulf looks like it's pretty 

filled with clouds, it looks pretty thick from here 

b etween 




to South America, 
a few clouds, but 
continent . 


S C 

We'll get back with 
S C 

spacecraft look to 
long as far as any 

w as s een here 




However, if you're interested in going 
the whole continent looks pretty good, 
for the most part you can see the entire 

Roger. It's summertime down there. 
Hey Gordo, we're stirring slowly, 
you here . 
Okay . 

Gordo, 1 question. How does the 
you? I didn't hear anything all night 
master alarms or anything. 

I m getting 
either. It looks 
Very good. 
Hey Bob, or 

and 2 OFF 

the word that nothing 
absolutely super. 

Gordo, I've got H2 heaters 

now , 

Roger, Gene 


APOLLO 17 MISSION COMMENTARY 12/7/72 14:49 CST 15:16 GET MC102/1 




Hello, Houston, America. 

Go ahead, America. 

Okay, Gordo, I'm looking 

today. We'll be with you with the 
marily it looks like a P23 day for 
like to do is spend a good part of 
cleaned up, reshuffled, re stowed a 

Ron. And 
that time 
little bit 

over the Flight Plan 
check list, and pri- 
what we'd primarily 
getting the spacecraft 
and get it in order for 

the next fews days ahead. It doesn't look like today's that big 
of a day . 


CAPCQM Gene, I might give you some words on what we 

have in mind to get the GET back in sync here, if you want to hear 
those while you're looking through the upcoming hours. 

SC Yes, why don't you pass a few words on that. 

CAPCOM Okay, the plan we're considering, and we're 

offering it to you now for your opinion, is at 65 hours GET we'll 
update and at the time the clock goes to 65, we'll update it 2 hours 
and 40 minutes up to 67:40. And we' 
such that you'll arrive at the Moon 
would have had you launched on time 

re shaping your trajectory 
at the same time GMT as you 
In other words, your trans- 

d ay 
an d 
H ow 

GMT , 


lunar time Is 2 hours and 40 minutes less. So once we do that, 
we' 11 be back with all the right times in the Flight Plan without 
any updating. And the one thing we think of is that your next 
will, which is now a 16 hour day, will shorten to a 13 hour 
20 minute day. But that's about the only real affect we can see 
does that sound? 

SC Yes, we - we'll get to the Moon you say the same 

so all our sunrise/sunset lunar orbit activity and sun angle at 
landing will be the same. And let me — it sounds pretty good, 
Gor; I just want to take a look at that day that you're shorten- 
what we're doing in there. 

Okay. It doesn't cut out anything. In fact, 
time that's pretty much dead time as far as the flight 
Take a look, and we'll talk about it later. 
Okay . 

Good morning, Gordie, this is Jack. 
Good morning, Jack. 

Le t me fill my square on that post-leak check 
got 24030, PRD? 

Ok ay . 

And, I slept in and out — probably totaled 
about 4 hours in that last period. But, I feel pretty good in 
spite of that and expect now that I've educated myself on how to 

an d see 
we picked a 
plan goes. 




I ' ve 



sleep that it'll pick up the next 
CAP COM Roger. 
SC No medication 

time around 

yet, but I'm considering a 

couple of aspirin. I'll let 
CAPCOM Roger. 

you know if I take them, 

APOLLO 17 MISSION COMMENTARY 12/7/72 14:49 CST 15:16 GET MC102/2 

SC And fluid -- let's see, I guess I've had two 

of your little water-measurement containers full so far, plus 
the meal I had in my pocket. And, I'll catch up on my -- I think 
I'm a little dehydrated, I'll catch up on fluids with breakfast. 


SC And my meal yesterday was the meal B in the 

pocket . 

CAP COM Roger. Meal B. 

SC And I guess consumables up to eight, that's 

mainly yours, there's plenty there, and I'll wait for your words 
on that, and the watch is wound. 

CAPCOM Roger. 

CAPCOM Okay, got the consumables up to eight num- 

bers if you're ready to copy. 

SC Not quite, Gordie, I'll give you a buzz. 

CAP COM Okay. No hurry. 

SC Okay, the CMP ' s rads 1509. 

CAP COM Okay. 

SC 15019. 15019. 

CAP COM Roger. 

SC Gordie, this is Jack. How do you want to 

send the consumables information? 

CAPCOM We were just discussing that here in Houston. 

In flights gone by, there was a place in the flight plan, a 
little form to fill out, but we're trying to figure out if there 
is such a place in the current data file. Do you know of one? 

SC No, I'll tell you what I've got on the con- 

sumables curves, and if there are any major changes to those 
curves, I guess you could give them to me, and I'll put them on 
as points. 

CAPCOM There's no place at all. 

sc Okay, and why don't we just do it that way 

in the future in case there is anything, and that's on page 145 
and subsequent in the flight plan supplement. 


SC It looks like you took good care of my space - 

my systems last night, 

CAPCOM No troubles at all. 


APOLLO 17 MISSION COMMENTARY 12/7/72 15:26 GET 14:59 CST MC103/1 

SC Okay, Gordy, your friendly medical officer 

up here has some more information for you. CMP continuing 
had about 3 hours of sleep, having had 3 cans of fluid - of 
water that is, and he ate everything in Meal B but the fruit 
cake and he didn't use the brownies and the beverage in Meal C. 

CAP COM Okay. 

SC Okay, and continuing the CDR's PRD is 

17019. He had 3 hours of fair sleep, no medication, and 1 and 
1/2 cans of water, and one/half a sandwich. The CMP 1 s sleep 
was 3 hours and I'll try to get more systematic as we go along 
h e re . 

CAP COM Okay. 

CAPCOM Jack, we are assuming no medication on the 

CMP. Is that right? 

sc That's affirmed. We haven't gotten that 

kit out yet. 

CAP COM Okay. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 15:10 GET 15:37 104/1 

SC Gordie , this is Jack. Looks like the 

windows have cleared up pretty well in PTC from the ice 
crystals anyway that were on window 1. The hatch window 
still seems to have a film of something on it, but otherwise 
they look pretty good. 

CAPCOM Okay, sounds good. Jack, while you're 

there you might try - we've been talking about consumable 
updates and what would be the most meaningful way to give you 
the information. As a trial for 14 hours with reference to 
the charts in the back of the book which in the case of - in 
case a lot of them are listed in percentages except the RCS 
which is in pounds. On the cryo quantities when I take 
all the tank percentages and plot them, it turns out that 
there is no real significant difference from the lines that 
are plotted on either hydrogen or oxygen. On RCS your run- 
ning about 3 percent ahead of the line. And if that's a 
satisfactory way to put it then that's the way we'll give 
you the updates rather than giving you every tank percent 
by percent. 

SC Okay, that's good (garble). 


APOLLO 17 MISSION COMMENTARY 12/7/72 16:03 GET 15:36 CST MC105/1 

SC Mark 2 aspirins for the LMP . 


CAPCOM Jack, next time the surgeon would like a mark 

on each individual aspirin. 

SC Well, I gave it to you since I swallowed 

them both simultaneously. 


SC I knew they wanted that, Gordy, and that's 

why I only gave you one. 

CAP COM Okay. 

SC Would they rather have them go down one 

at a time? 

CAPCOM I'll have to go back to the back room on 

th at . 

PAO This is Apollo Control, 16 hours and 

25 minutes. The Crew of Apollo 17 is now presently in a 
meal period. A little bit of levity a short time ago when 
Jack Schmitt, Lunar Module Pilot, called down to say: "This 
is LMP, mark, 2 aspirin." He had mentioned earlier in his 
post-sleep checklist that he was considering taking two 
aspirins. Apollo 17 is presently 72 843 nautical miles 
out from Earth. Velocity 6477 feet per second. We're con- 
tinuing to stand by on the air-ground circuit for further 
conversation as the crew finishes up their meal period and 
gets what few flight plan updates are involved in the days 
activity. At 16:26 and standing by, this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 16:27 CST 16:00 MC106/1 

CAPCOM 17, Houston. We see the optic starting to stir 

there, you can go ahead with a P52, but before you do the P23, we 
have some updates to it. 

SC Hey, Okay, Gordo, we'll do that. 

CAPCOM 17, Houston. Can you confirm that you did change 

your Li oH cannister, before going to sleep last night? 

SC Well, we can confirm that we didn't. How about 

th at ? 

CAP COM Okay. 

SC We'll, a-, thanks, thanks for reminding us. We'll 

try that first thing this morning. I was just getting too tired, and 
the C02 didn't look quite that high last night, so I a-, I let it go.

at a high gain pitch angle of minus 48 and a yaw of 315. Over.' 

sc Okay, 164301348 minus 48 and 315. 

CAPCOM That's correct. Now, go down a few lines to 

the sighting attitude at 17 hours and 15 minutes, and cross out 
that attitude and the high gain pitch angle and change to a roll

the yaw remains the same, 357. Over. 

SC Okay, 196304348 minus 61. 

CAPCOM That's correct. And, now, on the first star 

P23, we're going to change the star, so cross out -- replace the 
NOUN 70 numbers with star 21. That would be 3 balls 21. And, 
delete the NOUN 88 and the vector numbers there.

in the same thing as the same change as above. We want, instead 
of 175298330, change that to 164301 and 348, high gain of minus 48 and

SC It looks like Mexico in general is 

pretty nice; although, there is a band of eastwest trending 
clouds that start from the Gulf of California cross Senora 
and probably up through New Mexico and over into Texas as 
far around as I can see. Southern California looks like 
it's in pretty good shape today, but Northern California 
looks like it's probably overcast. And a major system probably 
associated with that that stretches into the northern western 
United States. But a band of clear weather looks like it 
stretches from Arizona right on up through I would guess 
through Colorado, Kansas and probably into the midwest pretty

CAPCOM breathing. His doctors report that their 

main worry is whether or not he is strong enough to withstand 
the strain the physical strain of 88 years despite the slight 
rally Truman's condition is still considered critical. In Paris 
Henry Kessinger met with Hanoi's Le Due Tho for four hours 
yesterday in planned secret talk. Paris newspapers report 
that eminant cease fire, but neither Kessinger or Tho indi- 
cate that this is true. After the four hour talks Kessinger 
shook hands and his aid, but neither representative made any 
comment concerning their meeting. At Camp David Maryland 
President Nixon's press secretary Ronald Ziegler said that 
Kessinger and Nixon are In close communication by cable con- 
cerning the secret peace talks. Ziegler declined to provide 
more information about the progress in the talks. President 
Nixon selected Claude S. Brenniger a California oil executive 
and a doctor of economics to be secretary of transportation 
succeeding John A. Volpe. Volpe will become U.S. am- 
bassador to Italy. Here's one concerning last nights launch. 
Mrs. Spiro Agnew reportedly made a wish on a falling star just 
before the delayed launch of Apollo 17. Sitting beside there 
at the VIP viewing site was Barbara Cernan who said that she was 
nervous when the liftoff was postponed. She added that 
Al Bean was there with me he said not to be concerned. Mrs. 
Cernan was accompained by her daughter Tracy and her mother Mrs. 
Jackie Ashly. Mrs. Ron Evans who saw the launch with her 
children Jamie and John said that she was never worried be- 
cause everybody knew what they were doing. 

SC Laughter. Good summary Gordo we thank 

you and our best wishes for the return health of Mr. Truman. 

CAPCOM Roger. 

SC Gordo, we were figuring up here that we 

probably launched on the 6th of December in Houston and on 
the 7th of December in Florida.

CAPCOM Go ahead, Jack. 

SC I mentioned to Bob yesterday how when we 

moved away from the. Earth how fragile a piece of blue it 
looked to be and that Impression certainly grows the further 
you get from it. I wish ever3'body could have a chance to get 
that impression. Things might: go a little easier for us. 

CAPCOM Roger. 

SC Okay, Gene, you are in CMC (garbled) 

SC (singing) You must be making the vector worse 

and worse instead of better. (laughing) Well, (garbled) the star 
points, half way through the Earth almost. Not really. 

SC Gordy, we haven't really had a clear 

and detailed description of what you or somebody else saw 
at the launch, in terms of the lightning around the countryside, 
the state of the flame and how long the exhaust was under the S-1C. 
Do you have anything to add to that? 

CAPCOM I can tell you my feelings anyway. There 

was a spectacular sight. There's no doubt about it. I'd say 
the level of illumination would have made it easy to read 
a newspaper or anything like that from my vantage point near 
the VAB, The plume itself was, actually looked no larger or 
even any brighter, really, except in contrast than it does 
on a daylight by comparison. But, oh, the effect I guess 

is about what I expected. Just trying to extrapolate previous launches 
into a night time situation. The weather was very clear. 
That was one advantage gained by delaying the launch the 
2 hours and 40 minutes that we did. By that time there were 
very few clouds around at all. And we could see a brilliant 
light there when the first stage cut off and the second stage 
ignited. And I lost you visually probably, oh, 4 to 5 minutes 
into the second stage as best I can remember. Part of the 
problem was the brightness of the plume during the first 
stage. It kind of burned a spot in my eyes, and so then I 
was - had reduced efficiency at looking for a small point of 
light from there on out. Stu's here with me and he was 
watching it to. I'll see if he has anything to add. 
SC Stu, who? 

CAPCOM He said after that comment he has no 

commen t . 

SC (Laughter) I'm sorry, Stu. I can't 

believe that, Stu always has something to add. (singing) 
Alright, you said in case you just noticed I forgot the first 67 
until just now. Although, in reality all we're 
trying to do here is get a DELTA H measurement anyhow. 


And you got any feel yet for what the DELTA H line has (garbled) 
b een ? 

CAP COM Standby, Ron. 

CAPCON Ron, this is Houston. We're not going 

to be able to give you a handle on the Delta H until 
we have a chance to take all the data and reduce it and work 
it around a little.

unit vector of the star. Okay, it's the 180 option we don't want 
Get me the real option. I guess - Houston, you must be getting 
all the good data without the high gain, huh? 
CAP COM That's affirmative, Ron. 

SC Okay. Okay. Let's enter that. Okay, 

Gene, go CMC 3 now. Okay, go CMC 3 now. Yeah, that's about

CAPCOM We have animated description of the behav- 

iour of a cloud of ice crystals drifting along with spacecraft 
is coming from Jack Schmitt. Apollo 17 at this point is 81 654 
nautical miles from Earth, traveling at a speed of 5972 feet 
per second. And we see from the telemetry data that the fuel 
cell purge called for in the flight plan at this time is pro- 
gressing. This involves flowing, in this case, oxygen at a 
high rate through the fuel cell for a short period of time to 
remove any build-up of contaminants. And, as a routine main- 
tenance or housekeeping procedure, same thing is also done 
periodically for the hydrogen. 

CAPCOM You can terminate the purge on fuel cell 3-02, 

SC Yes. I even forgot to listen for the bing 

on that one. Thank you. 

CAPCOM 17, we'll be having a communications hand- 

over to Honeysuckle in about a minute and a half.

look at the Earth, I'll see what's happening in Australia. 

SC Okay, Houston. We're starting our waste 

water now. Wish us luck. Wish us luck. Yes, that really 
goes out .

CAPCOM Okay, the vector's in there, it's your

sc Okay, Gordo, thank you. 

PA0 This is Apollo control at 19 hours 

7 minutes. The crew aboard Apollo 17 has completed the next 
item in the flight plan in the way of housekeeping duties 
aboard the spacecraft. That involved dumping waste water. 
Water is accumulated in a 7 to 8 gallon tank on the space- 
craft which is produced as a by product of generating elec- 
tricity in the fuel cells. These fuel cells generate quite 
a bit more water than the spacecraft is able to consume for 
cooling and for crew drinking purposes. The excess goes into 
a waste water tank and periodically it's dumped down to about 
lO^percent, and the crew has just completed that activity. 
We re going to take advantage of a relatively quiet time in 
the flight plan at this time to replay a portion of the air- 
to-ground conservations with the spacecraft which included 
among other things a rather detailed description of earth 
given by Jack Schmitt, some weather patterns. This replay is 
necessitated by a problem that we had with a portion of the 
public affairs release circuit between 4:40 and 5:05 p.m 
central standard time this afternoon in which a portion of 
the release circuit did not receive the air-to-ground and 
for the benefit of those people who missed that portion of 
air-to-ground we'll replay the tapes at this time. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 19:06 GET 19:32 MC120/1 

PAO This is Apollo Control at 19 hours 

33 minutes. That completes our replay of the segments of 
the air-to-ground that were lost on a portion of the Public 
Affairs Release Network earlier today. During that replay, 
we accumulated about 5 or 6 minutes of additional tapes with 
the crew, how the cictivi ties involved during that period of 
time or completion of waste water dump, the crew dumping 
excess water produced by the fuel cells and stored in a stor- 
age tank on the spacecraft, and they dump it down to about 
10 percent of its quantity, or its capacity. And, also 
completed one other routine housekeeping activity. That was 
cycling the film in the panoramic and mapping cameras con- 
tained back in the service module scientific instrument 
module bay. That bay, of course, still has the door over it. 
The door will be jettisoned before going into orbit around 
the moon exposing those cameras for use in lunar orbit taking 
high-resolution and very accurately controlled mapping cam- 
eras -- or mapping photos of the lunar surface. The cycling 
of the film is made necessary by the fact that the film is 
under some tension in the magazine in the transport mechanism. 
This tension tends to put pressure on the emulsion, and if 
the film is not advanced, oh, four or five cycles, at least 
once every 24 hours, it tends to create striations in the 
emulsion, and this is done during the translunar coast when 
the cameras are not being used periodically, once a day to 
prevent these striations from developing in the emulsion of 
the film. We'll replay that accumulated tape for you and 
then continue to stand by live. 

SC (garble) Are you going to want to cycle 

s ome film he re? 

CAPCOM That's affirmed. We're planning on it. 

Try and make sure they're ready, though, before you do it. 

sc Well, I didn't want to bring it up, but 

you're about 20 minutes late on your cue. 

CAPCOM You must have missed our first call. 

SC I probably did. 

CAPCOM Jack, we're ready for the pan and mapping 

camera film cycling. You haven't started into the procedure 
yet, is that correct? 

SC No, not yet. 

CAP COM Okay, at your convenience, we're ready 

to watch you do it. 

SC Okay. And, with those last high-gain -- 

I guess they're still good, huh? You want the high-gain on it? 

CAP COM Okay, we'd like you to use pitch at 

minus 50 and yaw at 320 and acquire the high gain. 

SC Okay, will do. 

CAPCOM You have 10 percent waste water now. 

You can terminate the dump.

you in a minute . 

CAP COM Ron, we're recommending AB for damping 

and BRAVO Delta for roll spin up. 1*11 say again. Alpha 
Bravo for damping and Bravo Delta for roll spin up. 

sc Okay, Robert, and welcome back aboard. 

CAP COM Roger, sir. 

sc You know, this eating in zero G's is 

not so bad if you keep your bags right side up. If you keep 
them that way, you get the right prospective. It's sure 
something funny if you turn the bag upside down, and it still

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 19:15 GET 19:41 121/1 

PAO This is Apollo control. That completes 

our replay of accumulated tape we'll now stand by for any 
live conservations with the crew. One thing additionally 
that we get out of cycling the cameras the panoramic and 
mapping cameras as an indication of how they are performing 
mechanically. As you heard based on the telemetry data that 
we got here on the ground both cameras appear to be functioning 
properly tucked away in the scientific instrument module bay 
of the CSM. You also heard some conservation with Jack 
Schmitt who is wearing the biomedical harness during sleep 
periods it's customary for one of the three crewman only 
to wear the biomedical harness which allows them to get heart 
rate during the sleep period and the crewman take turns wearing 
that biomedical harness and during the sleep we are getting 
good biomedical data good heart rate data on Schmitt at the 
present time. Also, Ron Evans commented on getting the 
spacecraft in the PTC attitude. Essentially, this attitude 
has the spacecraft oriented at right angles to it's direction 
of travel. Right angles to the Earth Moon plane so that the 
Sun is essentially shining on the sides of the vehicle of the 
CSM and LM. And, then using the reaction control system 
thrusters on the command module they set up a slow roll rate 
so that the two vehicles docked together are rotating at the rate 
of about three revolutions per hour. And, if this is done 
properly and it's a tricky maneuver usually crews get more 
and more experienced at it as they go through the mission, 
and tend to have the most problems early on in getting it set 
up. But if it is set up with all of the rates damped and 
everything very stable when the roll is started it will main- 
tain this roll without wobbling out of it throughout the rest 
period. The purpose of this is to maintain a proper thermal 
equilibrium on the spacecraft so that the heating on one side 
from the Sun the cooling of the other as it is exposed to the 
black of space is uniform and nothing gets too hot or too 
cold. At the present time Apollo 17 is 84 482 nautical miles 
from earth and the velocity continuing to decrease gradually 
down to about 5 824 feet per second just a little over 
one mile per second. We'll continue to stand by live now 
for any conversations with the crew. This could continue to 
be a relatively quiet period based on Ron Evans or I guess 
it was Jack Schmitt's comment that Evans was in the kitchen 
leads us to believe that they are probably getting ready to 
eat. This is Apollo control at 19 hours 45 minutes. 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 19:50 CST 19:25 MC122/1 

PAO This is Apollo Control at 19 hours 51 minutes. 

On the telemetry data that we have here in the Control Center, we're 
watching as the spacecraft is automatically killing off its rates, 
in preparation for setting up it's passive thermal control mode. 
They're getting the vehicles very stable, and they're measuring rate 
changes in thousandths of a degree per second. And when it is as 
essentially as stable as it appears possible to get it, they'll then 
fire the thrusters, to begin rolling at a slow 3 revolutions per hour 
rate. This is the second passive thermal control mode established. 

CAP COM The rates are looking good, they're amped 

adequately. We're ready for spin-up. 

S C Ok ay , B ob . 

PAO The crew set up the spacecraft in the passive 

thermal control mode before their previous sleep period and experienced 
no difficulty, and they appear to be going very smoothly. In this 
passive thermal control setup you heard CAPCOM Robert Overmeyer 
who's come in to relieave CAPCOM Gordon Fullerton, advise them that 
the rates have been killed off sufficiently to begin rotating the 
vehi c les now . 

SC Okay, Gordo, we're in PTC. Or Bob, I guess 

you're down there now. 

CAP COM Roger, Gene. 

SC Bob, did you ever find out what part of Antartica 

we were seeing at various Earth orientations? 

CAPCOM Jack, I've tried this afternoon and I couldn't 

get hold of anybody and I looked on map for awhile and I'm not sure 
where little America was. I can't truthfully say I did it. I'll 
keep looking at it. 

SC Okay, at any rate, it looks like there's a very 

well developed front coming out of the northwestern portion of Antartic 
ice shelf. And the front, and let's see here. Stand by 1. Have 
to change windows. 

CAPCOM Roger. 

SC Okay, Bob, that front, looks like it starts and 

develops as a small, it actually seems to start with an anti cycle 
in development off the coast of Antartica. Moves up across 
New Zealand. Looks like the south island primarily, a little bit of 
the north island is still visible. And into the eastern coast of 
Australia, I'll give you a spot where it intersects and crosses 
the whole of Australia. However, it breaks up and is not very 
well formed, once it gets inland away from the coast. I see no well 
developed waves on it at this time, so it's hard to say how strong it 
is. There might be one developing just to the south of New Zealand, 
or right off the coast of New Zealand. 

CAPCOM Roger. I copy that, Jack. 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 19:50 CST 19:25 MC122/2 

SC There at: least some sinusoidal motion 

or appearance to the front, and you'll have to wait because 
I lost it again. 

CAPCOM Roger. 

SC I took two 50 millimeter pictures, mag 

November, November is on 132. 

CAPCOM Roger, November, November on 132. Those 

are pictures of the ... 

SC And that was that - - 

CAPCOM Jack, Houston. Were those pictures of 

those fronts you were talking about? 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 19:35 GET 20:00 123/1 

PAO That was Jack Schmitt giving us the 

description of the weather patterns developing off the north- 
west coast of antartica and extending up towards New Zealand 
and Australia. Apollo 17 at the present time is about 
85 500 nautical miles from Earth and situated over the south 
Pacific. The spacecraft now essentially fixed with the 
respect to the Earth and Moon, but the earth rotating beneath 
it as the earth rotates - - 

SC Orbital map out now and that front is 

going off across the coast of Australia north of Sidney and 
largely a little south of Brisbain. And swings across the 
whole of Australia and seems to come as near as I can tell 
go by into the Indian Ocean about well where the great Sandy 
desert intersects the northwestern coast of Australia. 

CAPCOM Thanks Jack. 

CAPCOM 17, I've got a flight plan update here. 

SC Stand by, please. 

CAPCOM Ro g , it's just a short one, one item to 


SC Well, if you saw my hands right now you'd 

know why I said wait one. 

CAPCOM Understand I'm just waiting for your 

call didn't want you to think we're going to give you a 
whole (garble) rap of it. 

SC Oh, we know you wouldn't do that. 

CAPCOM If your eating Jack just go ahead and 

eat this is nothing that can - we can just wait and anytime 
2 us t go ahead . 

SC Yeah, I'm not pan icing. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 19:41 GET 20:08 124/1 

SC Okay, Bob go on the update and LM CM 

Delta-P at 20 (gable) . 

CAPCOM What do you know Jack we just got cut 

out by the antenna switching. Say again the LM CM Delta-P. 

SC Okay, 0.6 at 20 plus 09. 

CAPCOM Roger. Okay, my update is just simply 

on the bottom of page 3-23 at 23 hundred hours in the flight 
plan or 23 hours in the flight plan. Waste stowage vent 
valve closed just delete that one and move it over to 2430 
that's because you got started late on that. 

SC Okay, you could have just said move it. 

CAP COM Okay, just change It down to 2430. 

SC 2430. 

SC Okay, Bob revision 1 on my previous 

scratching of the letter on Australia that front does cross 
probably Brisban is probably cloudy it does cross about that 
area and however there is a bank of clouds that runs off of 
it down the coast line so Sidney is either cloudy or has 
some pretty nice clouds off shore. And the remnants of 
the front as it dissipates in the Hinterland of Australia dies 
out at about the Great Sandy Desert and there is not a good 
indication that it crosses into the Indian Ocean. But, we're 
getting over near the LM and that's a little hard to tell. 

CAPCOM Roger. 

SC Now, it looks more and more like there 

is a cyclone circulation developing right over the top of 
New Zealand the south island I think. And now I'm looking 
with the Binoc and as much at anti cyclone circulation is 
centered on the ice shelf and I think that well I just don't 
know I think that's the Ross ice shelf I'm not sure off Antartic 
and the clouds from that circulation do extend over the ice shelf 
and barely onto the Antartic continent. 

CAPCOM Roger, Jack. 

SC Now to the north of Antartica. 

let's see now I ought to give you a better orientation than that. 
Anyway, there is a large cyclone circulation pattern that 
has it's southern extremity right on the edge of the ice shelf. 
And that is east by 20 or 30 degrees longitude on the front 
that I was just discussing. The way that front intersects 
An t ar ti ca . 

CAPCOM Roger Jack. 

SC Between New Zealand and Australia the 

front I was discussing previously has some fairly strong 
transverse cloud patterns it's hard to say whether they are 
high cirrus or not, but the clear area to the south of the 
front suggests that maybe the jet stream is roughly parrelling 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 19:41 GET 20:08 124/2 

SC that front in that area. 

CAPCOM Roger. I'd have to look up and see if 

they do have any jet streams there right now. 

SC If I had to guess if you were flying 

west from Sidney this afternoon you'd have a pretty strong 
tailwind behind you, Bob. 

CAP COM Roger. 

SC Did I get that right. 

SC Would you believe a headwind? 

CAPCOM Okay, I'll believe that. 

SC But, the bulk of Australia is very clear 

all the south and the north. It's just that one line of 
clouds that crosses the center section. 

CAP COM Roger. 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 20:17 CST 19:51 MC125/1 

SC That put all the major cities of the 

South, Perth, Adelaide, at least, and Melbourne certainly in the 
clear. And in the North Darwin, in those areas, are very 
nicely clear today. 

CAPCOM Roger. I hope we can get this out to 

them and let them know you're watching and tell them how 
good the weather is. 

SC Oh, that's alright. I'm just having

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 20:40 CST 20:13 MC127/1 

PAO This is Apollo Control at 20 hours 

45 minutes. We're occasionally picking up a bit of noise 
on the Ai r- to-Ground circuit. This is due to the fact that 
the spacecraft is in the passive thermal control mode, as 
it rotates. We're gradually losing contact through one of 
the OMNI antennas and re-establishing adequate signal strength 
on another one. And as it moves from antenna to antenna on 
our coverage, we get the noise. This is a characteristic 
that becomes more pronounced as the spacecraft gets farther 
and farther from Earth. Here in Mission Control, the Flight 
Activities Officer has been actively involved in figuring 
out how in the flight plan we're going to make up for the 
2 hours 40 minutes difference from the flight plan liftoff 
time and the actual liftoff time. One of two things happen 
when you lift off late for a mission. Either the events 
that are called out in the flight plan occur at a different 
Earth time, Central Standard, Eastern Standard, or Greenwich 
Mean whichever reference you happen to be using, or the elapsed 
times change. And the flight planning is all done in terms of 
elapsed time for the most part. Events that are called out in the 
flight plan are listed by the amount of time that has elapsed 
from liftoff. At the present time, in the Apollo 17 flight 
plan, the amount of time that has elapsed since liftoff is 
unchanged from the pre-mission flight plan time. However, 
as, by the time we have approached or reached the Moon, be- 
cause of the speeded up translunar coast time, occasioned by 
slightly faster or slightly greater amount of energy that 
was put in during the translunar injection burn, we'll have 
to make up 2 hours 40 minutes. In other words, we'll be 
arriving at the Moon 2 hours 40 minutes earlier than flight 
plan allowed for. This means that all of the events that 
are called in the flight plan to occur between now and lunar 
arrival have to be accomplished in 2 hours 40 minutes less 
time than the flight plan allows for. This creates no serious 
problems, because it's a relatively quiet period of the 
mission. It's very easy, by adjusting sleep period slightly 
and moving the activities up to accomplish it. However, 
the flight planning officer, flight activities officer, pre- 
fers to accomplish this shift in two increments rather than 
a single one. And this could be likened to a change of 
daylight savings time, where you don't want to make the jump 
too big at once, and you might start interfering in a way 
that would be noticeable, say, with sleep periods. But by 
accomplishing it in two segments, the change is relatively 
insignificant. And what this amounts to is that at two 
different times In the flight plan, we'll read changes to 
the crew, and they will go down the flight plan, moving a 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 20:40 CST 20:13 MC127/2 

P AO series of events approximately 1 hour 

earlier. The second time that this is done, they'll 
actually be moving events 1 hour 40 minutes earlier and at 
the same time, we'll update the clocks in Mission Control, 
the Ground Elapsed Time clocks, which serve as the key to 
where you are in the flight plan to agree with the changes 
we have made in the flight plan. And from that point on, 
the GET clock will be back in synchronization with the 
flight plan. This clock update is presently scheduled to 
occur at 66 hours Ground Elapsed Time, rather at 67 hours 
40 minutes Ground Elapsed Time, and we'll move the clocks 
to 66 hours. Apollo 17 at present time is 88 091 nautical 
miles from EARTH. 

SC Checking on the Ross Sea, and if I've 

got her pegged right, it's got a fair amount of open water 
in it this time of year. 

CAPCOM Roger. 

SC Although, it's completely surrounded, I 

think, completely surrounded, I think by portions of the 
ice pack. And off to the west of there, it looks like there's 
an area that might be clear of snow, and if my memory serves 
me correctly, that's where MacMertle Sound is, and some of 
the dry valleys? 

CAPCOM I believe so. That's the Little America 

area right now, all that general vicinity, Jack. 

SC Okay, it looks liks the prime recovery 

area. The Samoa Island region is clear and my guess would be 
from the fairly subdued zero phase point, that they might 
have fairly nice seas out there. The boys on the Ticonderoga 
are probably enjoying themselves immensely, I hope. 

CAPCOM Roger. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:26 GET 20:50 128/1 

SC Indonesia looks like it's having a nice 

day, with the possible exception of the region over just 
north of Australia. New Guinea and that area some clouds in 
there I can't tell whether they are high or low clouds though they 
look like they're probably fairly high clouds. But north of New 
Guinea there is a strong concentration of clouds although small 
and looks fairly dense like there might be a little tropical de- 
pression in that area. 

CAPCOM Roger. 

SC The folks in Carnarvon ought to be enjoying 

a very nice day. I've been trying to spot tropical storm 
Teresa which a couple of days ago was in the Phillipines. I 
don't think I quite have that visible to me right now. 

CAPCOM Roger Jack. Say, you might want to put 

something in the back of your mind here a minute we made a 
run of the DS E recording just now of the T LI to get an idea 
of the quality of the DS E recording and Gene came through 
loud and clear. Ron was very weak and almost unreadable and 
we never caught you Jack. Maybe you weren't saying anything 
during TLI , but we never did catch anything you said. 

sc Okay, I don't recall talking to much 

during TLI. 

CAPCOM Roger, understand. Now Gene came through 

real loud and clear so whatever technique he was using went 
on that tape real well. 

CAP COM Hey Jack, Houston. 

SC Hello. 

CAP COM Hey, Jack just a couple more comments 

on that DSE. I think as you well know it's very critical 
on the position of your boom there and those areas that you 
are critical in make sure that you've really got those 
beauties up or your talking right in to it and this really 
makes a difference because the DSE - the volume is fairly 
low, and if you're muddled just the least bit why it's going 
to be difficult to pick it up. So talk slow and get right 
up next to the mike as I know your doing, it just that 
some voices come across a little better than others. 

sc Roger Stu, thanks for the comments as a 

matter of fact you probably called it just right I think 
during - once I got the helmet off I loosen up my chin strap 
and my mike had moved away from my mouth some. And I'll keep 
that in mind. Thanks for the reminder. 

CAPCOM Yes, that's probably the most critical 

item is that - is the position of those and this has been 
true in the past and it just really makes a difference in 
being able to pick up the data off the voice. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:26 GET 20:50 128/2 

sc Roger I've - Ron and I did some experi- 

mentation with that in the chamber and couldn't agree more. 
But, I sometimes don't remember it. Thank you. Okay, go 
ahead, Stu. ' 

CAPCOM I'm sure your aware of that, but I think 

the fact that the volume is down just accentuates the problem, 

SC Okay, Gene had s one thing he wanted to 

ask you. 

sc Stu, I just thought you would like to 

be aware of it as much time as we've all spent down at the 
Cape probably May is one of the nicest months down there 
however, having had the opportunity to be up here during 
May I find out that it's not nearly as nice up here 

CAP COM Okay. 

sc And, I'd like to thank all my friends 

for that. 

CAP COM Okay. 

PA0 This is Apollo control at 21 hours 

3 minutes. Things continuing to progress smoothly and very 
quietly here in mission control and aboard the spacecraft. 
And we'd like to have a bit more discussion of the ground 
elapsed time update after first making the disclaimer that 
GET clock updates are not done for the purpose of confusing 
people; although, I'm sure it seems that way at times. And, 
by way of clarifying the previous description of this GET 
update we should point out that the amount of time that the 
clocks are changed both here and mission control and aboard 
the spacecraft will be 2 hours and 40 minutes and this clock 
change is scheduled to occur as mentioned previously at 
about 65 hours ground elapsed time. In other words when the 
clocks here in the control center and the clocks in the 
spacecraft keeping track of the time that has elapsed since 
liftoff reach 65 hours they will be arbitrarily jumped ahead 
2 hours and 40 minutes so that at that point the clocks agree 
with the flight plan. However, in order to account for 
these 2 hours and 40 minutes which are suddenly going to 
disappear from the amount of time available to the crew to 
accomplish their activities to make it easier on the crew 
it will be done in two increments. The first increment of 
1 hour and the second increment of 1 hour 40 minutes. And, 
at about the time the second increment of change is made in 
the flight plan we'll also simultaneously update the clocks 
Apollo 17 at this time 88 909 nautical miles from Earth and* 
the velocity continuing to decrease gradually down now to 
5 603 feet per second. Very little activity is scheduled 
in the flight plan between now and the time the crew begins 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:26 GET 20:50 128/3 

PAO it's rest period. This day aboard the 

spacecraft has been planned as a relatively short one recog- 
nizing that the crew would not get a great deal of sleep on 
that very long - as a result of the very long launch day. 
And a relatively short sleep period following. This day was 
intentionally kept short. They're now - should be completing 
their eat period although they really have nothing showing in the 
flight plan until about 22 hours or about another hour from 
now where they have alloted time for an exercise. They will 
be changing the lithium hydroxide canisters that remove carbon 
dioxide from the spacecraft cabin atmosphere. They will be 
realigning the spacecraft pla.tform the stable platform that's 
used as an attitude reference by the guidance navigation and 
control system. Then they have one more eat period and go 
through the pre sleep check list beginning an 8 hour rest 
period at about 25 hours ground elapsed time or a little less 
than 4 hours from now. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:40 GET 21:07 MC129/1 

SC Bob, you with me? 

CAPCOM Roger. We wouldn't go away, Jack. We're 

listening. Did you call? 

SC Well, I just — yeah, I almost lost a 

pass here and just a couple more words about Australia. As 
a general land mass, it's red. Very strong red hues, except 
for the north and eastern coasts, where that red gradually 
merges into a greenish-gray . It's as red as portions of northern 
Africa appeared to me yesterday. 

CAPCOM Roger. 

SC Very striking color. It would be more 

of an orange-red, really, with brown subduing it. It's obvi- 
ously not crimson or anything. 

CAPCOM You think it's a function of sun angle, 

Jack, or is it just a red like we see out in the New Mexico 
area sometimes — some of the areas? 

SC Yeah. No, it's not sun angle, because 

that'll hold a good red color right in towards sunset or 
sunrise. It's due primarily, I'm sure, like most desert 
areas, to the oxidation of the iron-bearing minerals in the 
sands and rocks in those regions. 

CAPCOM Roger. 

SC Getting limanite and hematite. Little 

geology thrown in there, Bob. Sorry. 

CAP COM That's all right. Gotta keep you warmed 

up for the next couple of days. 

SC I think the flight plan will probably 

keep me warmed up, too. 

CAPCOM Roger. We thought that time around 

T £c D was just outstanding. 

SC Hey, Bob, I think we pretty well got 

impressions from you down there on that night launch. I 
might give you a few of mine. 

CAPCOM Go ahead, Gene. 

SC (garble) right there. 

CAPCOM You're right on the edge if you read me. 

We're getting a lot of static. If you'll just hang on a 
minute, we'll be back in to some calm air. Gene, Houston, go 
ahe ad . 

CAPCOM We're just standing by for your comments 

you wanted to make when we lost comm there a minute. We're 
back with you. 

SC Okay, Bob. The entire boost itself was 

not unlike what you - Stu - down there understand. The physi- 
cal cues, what have you, but the significant part of going 
at night is that as soon as we did have ignition down there 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:40 GET 21:07 MC129/2 

in the bottom of the SIC stack, even though I only have a 

little slit out of the rendezvous window here, and Ron 

doesn't have much of a hole in the boost protective cover 

out of the hatch window, we could definitely confirm ignition 

because we could see the reflected lights on out through — 

in front of us. It was by no means blinding, of course, we 

had the cockpit pretty well lit. We — as soon as we lifted 

off, that light immediately went behind us. We came into 

SIC staging, and I had an opportunity to say "I told you so" 

to Jack and Ron. It was just like the great train wrecks of 

the past. I definitely could see the S2 ignite, and, then, 

of course, I could see the significance of the reflection 

through the window. Besides all the other cues we had for 

ignition, very much like the SIC lit up the windows on the 

stack. Power jet was pretty spectacular. I could see out 

the entire boost protective cover, and some flames from 

somewhere — I'm not sure -- maybe it was through the hole 

in the window — but I could definitely see it. Of course, 

it disappeared in short order. When the SII shut down, the 

delay time between shutdown there and the S-IVB igniting, the 

entire flame overtook us, and we literally flew through the 

SII flame when the S-IVB ignited, if you can imagine that. 

It's very similar to the Titan staging where you actually fly 

through the fireball on the SII. An d , that's something you 

never see — none of those things you ever see quite that way 

in daylight. On the S-IV I could see — of course, once we 

got going, I couldn't see any light from that plume again, but 

we could see the APS firing all the way through the burn, and once 

we got in orbit, as other guys have seen, you could see the 

APS firing that night without any difficulty. One of the 

most significant things about TLI is the fact that we, of 

course, started at night and flew right on up and through 

a sunrise which in itself was a pretty spectacular thing, 

but, when you do it during a TLI burn it even adds a little 

bit momentum to your effort,. 

CAPCOM Roger, Gene. Any comment you might make 

on the possibility of picking up your yaw, if you'd lost 
your platform that time — remember the discussion we had 
about the yaw in the late like a mode force went in? 

SC Yeah, Bob. I not only will comment. I 

was aware of it, and I was looking for it, and during parts 
of the SII and parts of the S-IVB burn, I even turned the lights 
down in the cockpit in hopes that I could see stars out 
there, but I could not make out a one. Ron, I think, maybe 
saw Saturn out the overhead hatch, but looking through the 
rendezvous window during a boost phase during a time- cri t i cal 
phase like a Mode 2 or Mode 4, I am very much afraid that 
we would not have been able to pick up that reference. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 20:40 GET 21:07 MC129/3 

CAPCOM Roger. 

SC As I remember it, as low as I had the 

interior lights there for a period of time, and I didn't 
want to keep them that low, of course, to see if I could get 
adapted very fast, because we were in a dynamic phase of the 
burn, but my window just gave me a very deep purplish hue, a 
hue of which I could not, literally, see through to look to 
see any stars at alL. Now, that may have been due to the 
very low intensity of our interior flood lights. 

CAP COM Roger, Gene. 



SC Bob, this is Jack. A little lay im- 

pression there, I think I saw just about everything Gene was 
talking about as far as his description and felt like it was 
- although everthing was an imazing experience, each one in 
itself, after each one was over, you could think back and 
say: "Yeah, that's what other guys said it was like." The 
old Saturn V has got to be a pretty consistently performing 
vehicle. But with the added night time contrast, I think it 
made it probably the best ride any three guys have ever had. 

CAPCOM Roger. 

SC Bob, I might add, that the S-l was, as usual, 

pretty shakey on lift off I s aw all the maneuvers as I called 
'em out to yaw and the small reverse roll. Going through 
Max q, I .got up to 25 percent, but my yaw attitude was error zero 
and my pitch attitude error probably wasn't even at oh, certainly 
less than 2 degrees. After raax q she smoothed out by comparison 
quite a bit and the S-II was a very quiet ride, a very smooth 
ride. However, you are always aware, due to just a little 
rumbling out in the S-IVB, that she was still burning for you. 
The S-IVB I think was just a continually rumble, but smooth or 
consistent ride all the way through GL I . 

CAPCOM Roger. 

SC Gee! I think one of the big things that 

impressed me was the - how instantaneous the de cellerations 
were of each one of the boosters when they cut off. That 
included the S-IV TOI cut off. No physical appreciation of 
tail off at all. Hey, Bob, from my rendezvous from the right 
hand rendezvous window when the tall jet occurred, there seemed 
to be a lot of burning particles streaming away from it. I 
could not see - did not notice - remember seeing the actual 
cover or tower itself, but we were inside the cone of the 
burn and with a lot of streaming, it looked very much like 
a sky rocket. Portion of one at any rate. Reminded me of the 
4th of July out in Silver City a few years ago. 


CAPCOM Say, any time you got your flight plan 

handy, I've got a discussion here I'd like to run through 
here with you now on how we're going to recover those 2 hours 
and 40 minutes from the launch delay and you'll need to copy 
it into the flight plan, and then just want you to be 
advised we're not happy with the PTC, we get a half angle 
of about 17 degrees and so sometime after the P-52 coming up 
in 2300 we'll want to do another PTC, or initiate PTC again. 

SC Well, that was the commander who initiated 

PTC and I've already heard about that. You bet he has. 
Okay. We've got the flight plan here, Bob. Which part of 
it are you talking about? 


CAPCOM Well, let's just talk some words here for 

a minute and then I'll go through some specifics you can 
just write down on a page cause you don't want to do it until 
a little later. Okay, what: we're going to set up here, you 
will arrive at lunar orbit at the same GMT time to landing sun 
angle, sun elevation angle, and the camera settings and every- 
thing will be unchanged when you get to Lunar orbit. To com- 
pensate for the 2 hours 40 minute late launch we're going to 
tack 2 hours and 40 minutes out of the time line and we're 
going to, they'll be out of the TLC timeline. We're going 
to do it in two groups, and this is where you might want to 
start copying now, Ron. Delete 1 hour from 46 to 47; from 
46 to 47 we're just going to delete the activities that are 
presently scheduled at 4630 to 4700, you'll perform at 45; 
move those to 45. Let me read that again. Delete 1 hour 
from 4600 to 4700. The activities that are listed at 4630 
to 4700 perform at 4500. 

SC Okay, Bob, looks like we delete 1 hour 

from 46 to 47 hours and then the activities that are at 
4630 do those at 4500. 

CAP COM Roger, Ron, and then starting at 47, 

just take, just scratch 1 hour off of each time, just subract 
1 hour from each of those times up through 66 hours. Sub- 
tract 1 hour from 47 up through 66. 

SC Okay, we can do that. Subtract 1 hour 

from 47 to 66 hours. 

CAP COM Okay, and just for your information 

you won't have to do it, but we're going to play the old 
simulator step-ahead game at 66 hours to the old time which 
will be 65 hours of the new time to however you want to 
call it, we'll call you when we're going to SINC you up 
at 6740 at that point. 

SC We'll play the old step-ahead game there. 

Okay, Bob. That means that you're not going to actually 
do any clock updates or SINC's until somewhere in the 60's 
there and not in the 4 0's. 

CAPCOM Roger, it'll be 65 hours of the new time 

or 66 hours of the old time, depends on how you want to look 
at it. But that's when we'll SINC you up. 

SC Okay. 

CAPCOM You'll be in SINC all the way out to that 

time, just, we're just going to delete and jump you to 
6740. And just another note of interest, you don't have to 
write this down, but let's see I'll read it to you. The 
awake periods will be on days 3, you'll be 15 hours, 8 hours 
sleep starting at 11:33 CST ; then at Day 4 you'll be 14 and 
20 hours with 8 hours sleep. So you'd actually just shorten 
a couple days there. 

SC Okay, mighty fine. 

CAPCOM The beauty of that that Tommy came up 

with on that, Ron, is that all you have to do is go subtract 


those one hours and no more reading or anything else, just 
subtract them and we're in business. 

Yeah, it looks real fine. 
We're going to give Tommy a gold star 


for that one . 

Jack, I'm going to

Okay, if we can We'll keep 


Bob, just to keep you and the people there 
bit, today is a relatively short day, but 
because it gives us a chance to again get 
acclimated and finish our stowage and just generally go through 
all the things that have to be going through for the rest of 
the mission. We've got three eating days today, and judging 
from what we're thinking and talking about now, that the last 
two are going to be sort of stretched into one eating period 
because three meals on this particular day just is not 
going to be stamachable. 

CAP COM Roger, we understand that. 

SC I think you'll find out that our eating 

and drinking for the most part is starting off relatively 
slow but I think we'll pick it up by tomorrow. 

CAPCOM Roger. 


APOLLO 17 MISSION COMMENTARY 12 jl 111 GET 21:30 CST 21:05 MC131/1 

SC Bob, one other thing while I'm thinking about 

it, the PU shifts were all noticeable, but probably the one that 
really caught me a little bit by surprise was the PU shift on the 
S-IVB during TLI. 

Ro ge r . 

It just felt like you lit in the other burner.

right now. How you're slowing down again. 

Flight surgeon John Zeigelschmitt is watching 

the heart rate of Jack Schmitt, as Jack exercises aboard the space- 
craft using a modified exerciser, that consists primarily of a 
cylinder and a cord that comes out of it allows him to adjust the 
amount of tension or resistance to pull that the device has, and 
there are a variety of ways in which it can be used, allowing him 

adjustable tension. This bungee

Roger. We have a comm outage. I'll be right 

Okay. Very fine. How are things down there 

Fine. Your weather report was beautiful. 
Oh, your country looks beautiful from here. 
Okay, 17, Houston. How do you read now? 
We got you, Bob. 

That was our network problem. Not your prob- 

Okay thank you. I just figured out what 
Your, with his exercise, Jack, is shaking 
all of America in all three axis, here. 

CAPCOM Roger. He finally got to 115 on the heart 

rate . 

SC Yes. My rate needles are bouncing back and 

forth a half a degree. 

CAPCOM Roger. Got to find something to pin it on. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 21:16 GET 21:43 132/1 

CAPCOM Jack surgeon over here says you've got 

a 120 on the heart beat for a moment there, a 122 right now. 
Okay 130 Jack, 130. 140 Jack 140. 

PAO The numbers reported to Jack Schmitt by 

capcom are his heart rate and you heard him report a heart 
rate up to about 140 beats per minute as Jack is apparently 
continuing to exercise vigorously with the onboard exerciser. 
This is aimed among other things at keeping the cardio 
vascular system which tends to get lazy in zero gravity in 
condit ion . 

CAPCOM Team we've got a serious one here you 

might be interested. All that exercise banging around in 
there has destratified tank 3 02 so it stirred it all up good. 

SC Yes, glad we brought him along then 

we found some use for him. Once an EE COM always an EECOM. 
I have to create my own g in order to run in place. 

CAPCOM Roger. 

SC How high up did the heart rate get, Bob? 

CAPCOM We got you at a 140, Jack. Were you 

running in place? 

SC 140 was that - yeah, I was underneath 

the righthand couch holding on to the main YY strut with 
my hands and running against the LEB. 

CAPCOM Roger, it worked real well 14 0 and you 

were running in the mid 60 's so you picked up to about al- 
most 70 beats there no problem. The surgeon is very happy. 

SC Roger, well I'm happy too. It took a 

while to find a technique I was - initially I got up to 90 
with just isometrics pushing against the couch and the running 
is obviously what it takes. 

CAPCOM Roger. 

SC But I don't - Bob I don't I really don't 

feel I guess I lost you. 

SC Hello Houston, 17 are you still there? 

CAPCOM Roger, we're with you we had a little 

coram problem there as you know, coming on this as we're 
changing on the antenna. 

SC Okay, what's the heart beat right now? 

CAPCOM Right at, stand by. We had a data 

drop out, Jack, that's why I'm holding up. And It just came on 
we'll tell you in a second here. About 60 Jack right about 
6 0 even . 

SC Okay, that's where I was when I started 

so you certainly recover fast. I don't know if that's 
faster than in one g or not. 

CAPCOM Well, we're happy with it, or the surgeon 

is happy with it so it's good. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 21:16 GET 21:43 132/2 

SC Well, I just how does that compare - do 

we have any data how that compares with the recovery - say 
the five minute recovery time on the ergometer. 

CAPCOM We can look it up, Jack if your interested 

We'll have to check your records they don't have it right in 
f ron t of us . 

SC No big deal I was just curious. 

CAPCOM Roger. 

CAPCOM Jack, just for your information the 

surgeons pulled out the recovery rate data and the same with 
our data which is a little rough here it's the same zero g as 
your 1 g odometer data. 

SC Okay, that's very interesting. 

CAPCOM Roger. 

SC Bob, since we've got a few moments to 

talk which I know we won't have later in the mission some- 
thing I don't ever remember happening, but it's happening 
now in the windows. That's the 1, 3, and 5 but not 2 and 4 
is that in the center of the window about 6 or 8 inches 
in diameter as you come through the night side of the rota- 
tion you pick up a very light - oh, you might call it even 
a frost. Very light frost on the window more like a mois- 
ture frost film of moisture or a film of frost not very thick 
like crystals at all as you come through the sunlight it 
tends to sublime away, but you never fully lose until you go 
back into darkness again. The very artistic definite 
ice crystals that we had on my number 1 window here yester- 
day I think we reported to you this morning that they were 
gone or sublimed away. But the impression they left on the 
window is still there very sharp and very evident. 

CAPCOM Roger, we copy that. 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 22:01 CST 21:36 MC133/1 


Honeysuckle ' s 

the re , Jack . 


Bob, I don't know whether you were copying 
call to us, while yoxi lost COM there for awhile. 
Roger. We copy. 

But they said that they had (garble) okay. 

They kind of concurred with your weather report 

Oh, lucky guess. I might 
the zero phase point that we're looking at 
coast of Australia and it's much brighter, 
now, oh, it's hard to say how far across. 

say that the sub, 
is right at the northeast 
It's a very bright point 
But, quite unlike what 
I mentioned being in the vicinity of the Samoan Islands earlier. 
And it's right at the shore and it could be just that the shore 
area has somewhat choppier seas. So maybe, maybe the brightness 
of that point is a function of sea state, although I don't know 
exactly what type of seas it would take to brighten it up. I 
suspect choppy seas are better than long swells. 
CAPCOM Roger, Jack. 

SC That front is - seems to have slowed down it's 

progress. It's about in the same position, possibly slightly 
farther north than when I started talking about it this morning. 
The waves seems to be developing off the - now off the southwest 
coast of New Zealand. It's much more pronounced than it was. 
Definitely seems to now have a slight cyclonic pattern - clockwise 
pattern. And I wouldn't be surprised if the next couple of days 
that moves along the front over towards Sidney. And maybe a little 
farther north than that might - Brubane is probably more likely. 

CAPCOM Roger, Jack. 

SC Now except I got the movement wrong again. 

Although it does seem to have progressed west from New Zealand. 
CAPCOM Roger. 

SC I take back what I said about forcasting 

Sidney's weather. I think that will - I would suspect that would 
move to the northeast like - now that I look it seems like an 
earlier front, which is partly disipated, has the same kind of 
motion and now lies considerably north and east of the one I've 
b een 

talking about.

loud and clear 

APOLLO 17 MISSION COMMENTARY 12/7/72 GET 22:01 CST 21:36 MC 133/2 

SC Okay, I'm going to try to recover there from 

that last few statements. As I recall, the weather briefings that 
we had at the Cape last week, that - talking with Ken Nabor and 
Jim Nicholson down there, that the patterns that we were seeing 
from the satellite pictures in their forcast, or analysis anyway, 
charts in the New Zealand part of the Pacific, those waves formed 
along the front would move north and then curve east. And that 
appears to be the pattern that was visible in one of the older 
fronts. And I suspect that that pattern would hold with the wave 
that's developed off the coast - right on the coast of New Zealand 
now. It might move on up the western coast of New Zealand. We'll 
probably have a chance to watch that in the next few days and 
see what happens to it. 

CAPCOM Roger Jack. 

SC Houston, how are you reading now? 

CAPCOM Reading you loud and clear. 

SC Okay, Bob. As I look at the clock, we're - 

just 24 hours ago we were within our hold somewhere. For this 
period yesterday we were in our hold, and I think it goes without 
saying, but we'd sure like to pass on our bit of gratitude and than 
for the response that the people down at the Cape came up with. 
And particularly at Marshall. I think we all knew no one would be 
going anywhere unless everyone was satisfied that we were going 
all the way, and that's certainly the way we felt, but we do want 
to thank everybody there for making that come true. 

CAP COM Roger, Gene. I think it was a superb show 

between the Cape and Marshall and Houston and probably with 
Goddard with the network and just about everybody concerned, 
really. Had to do some work there to bring it off. And it went 
off real smoothly. 

SC Yeah. After flying with Stafford a couple of 

times and having that happen a few times back, I thought maybe he 
was aboard. 

CAP COM (Chuckle) Okay. I think that was a first 

for getting a Saturn V to 30 seconds before ignition and - or 
rather actually 30 seconds before liftoff and holding there. 

SC It got mighty quiet on board about 30 seconds. 

CAPCOM I sure imagine. 

SC We all felt like old hands the second time 

around, though. 

CAPCOM Roger. 

SC Bob, I've been at that 30 second count one 

other time and it's no different the second time around. 
CAP COM Roger. 

SC But we do appreciate the work and I think 

it's typical of - of what made this manned space program such a 
super program. The responce of people like that. 

CAPCOM We concur with that Gene, wholeheartedly

Roger, that's - that's our feelings here, 
Gene and Ron, I talked to your fraus on the 
a little while ago and they gave me a very inter- 
esting observation you might appreciate. They were standing 
close to some water when launch when they noticed that when 
the booster lit up there was something scared all the fish 
because the water literally began to boil with fish jumping 
from the light, I guess, or from the Shockwave or something. 
It must have made a very distinct impression because that's 
the first thing both of them told me about. 

SC Yeah, that's pretty neat. 

CAPCOM A neat way to go scare up the fish, I 

guess . 

SC Right. How are they doing today, Bob?

don't be expecting too much. 

Acclimation and familiarity, stowage and 

preparation, and enjoyment and relaxation - are ready to call

APOLLO 17 MISSION COMMENTARY 12/7772 22:05 CST 2231 GET MC135/1 

SC Bob, how do you read 17? 

CAPCOM 17, read you 5 by. 

SC That's strangest sounding Bob I've ever 

CAPCOM He's taking a short break. 

SC Okay. Good. Nice to talk with you. 

Hey, I don't know whether you were Gene the other day when 
talking about the circulation patterns around Antartica. We 
were looking then at the Indian Ocean, or actually the south 
Atlantic in the Indian Ocean region, and you see the same 
pattern at about the same latitudes, say 60 degree south, where 
all the linear cloud patterns which presumably are - reflect 
the various cold fronts have - are arcuate with their convex 
sides, or actually almost pointed sides - are all lined up 
in a west-east direction around that latitude. It's quite 
a spectacular appearing circulation pattern and the little wave 
that I mentioned on New Zealand seems to be - beginning 
to form another arrow or another convex point on that front 
that's fitting right into the same circulation pattern. 
CAP COM Okay, copy. 

SC That would make four of those major convex 

fronts that I can see from this view crossing south of Australia 
up into the South Pacific. 


SC On that tropical storm that was Teresa, I 

don't know if they're still calling it now - that now, but I'm 
not sure it may be a little south of Guam. Guam may not be 
in trouble with that one. 

SC It looks like its just a bit to the west 

of Manila there about 5 or 6 degrees no more than that though. 
It looks like it's about 5 degrees west of Manila and about 
5 degrees south. And it is still called Teresa. 

SC Okay, Gene, if you're still there, I don't 

like to argue with you but I think our analysis chart is a little

SC That area that you just mentioned is very 

clear now. East of the Philippines. Did you say west or 
east of the Philippines? 

CAPCOM West of the Philippines. 

SC Okay, that: area that you mentioned, 5 degrees 

east is very clear and the center of ten - the - what appears to be 
the storm that I'm speaking of would be about 142 longitude 
and may be 8 degrees north latitude. 


SC Which would put it south of Guam. 

CAPCOM Okay, Yeah, you're over in the area between 

Guam and the Carolines, then. 

SC Say again, Gene? 

CAPCOM You're over in the area between Guam and 

the Carolines, then. You're saying it would be just about due 
west of the Carolines, then. 

APOLLO 17 MISSION COMMENTARY 12/7/72 2205 CST 2231 GET MC 135/2 

S C Yes , sir. 

CAP COM Okay. 

SC Yeah, you're probably looking at a - oh, 

I don't know - maybe a what - a 12 hour old prog, or something? 

CAPCOM 5feah, that's the one I had for launch day. 

SC Okay, well its moved quite a bit now, and 

I guess its the same storm, still seems to be very well organ- 
ized but quite concentrated and small. 

CAP COM Okay, I'll get a new prog in and compare 

your estimate, there. 

SC Okay, I think that's pretty good - those 

142 and 8 degrees would be pretty good center of that storm. 
That's a pretty good - I can see Mindanao and I can see the 
- let's see - just a second - what is that on Australia? Yeah, 
of course, that is Port Moresby. I can see that point there 
and it's between those two - I can pin that one down probably 
within a couple of degrees. 

CAP COM Okay. We'll get a satellite photo and 

bring it in here in just a bit. 

PAO The conversation over the past few minutes 

has been between Flight Director, Gene Kranz, and Jack Schmitt. 
Apollo 17 at this time, almost directly above the northeast 
coast of Australia - some 94 000 nautical miles from earth. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 22:19 GET 22:44 MC 136/1 

SC Ah, Houston, caster number 4 is in 

Bravo now. 

CAPCOM Roger, we copy that. 

SC Houston, 17. 

CAPCOM Go ahead 17. 

SC Okay, Bob, that storm off the - just 

off the southwest coast of New Zealand is still intensifying 
and has both high and low level clouds you can see by 
shadow lines. It looks like it may go into pretty fair 
storm system. Borneo is very clear today and the Phillipines, 
as I mentioned, it looks like a very strong frontal system 
that stretches from, oh, let's say the south coast of, 
southeast coast of Viet Nam up between the Phillipines and 
tawan and across tawan and right along and I can't tell, I 
think just off - just south of Japan, I can't tell whether 
Japan is in the front or not, I'll look at it some more. 
The strongest storm center that I can see on that is way 
north and probably Hokkaido has a fair amount of weather 
from that storm system. There seems to be a tropical 
depression just north of Borneo, very strong circulation 
system north of Borneo and I guess just south of Viet Nam. 

CAP COM Roger. 

SC Probably southeast. I hadn't noticed 

it before, but it is extremely concentrated northern 
hemisphere cyclone pattern. I don't know whether that's 
on your prog or not. That's not what's left of Sally is 

CAP COM Standby, let me look at the prog over 

here, Jack Okay, we - it doesn't show on the old one, the new 
one is coming in here shortly, Jack. 

SC Okay, if that is a developing depression 

it's approaching Luzon and not very far away - 2 or 3 degrees 
of longitude now, but Luzon is clear. 

CAPCOM Roger. 

SC I can see Korea quite well, Bob. It's 

clear today. 

CAPCOM Yeah, we've got the fronts, the leading of 

the front on our prog was past Korea and on Japan and you've 
got it moving quiet a bit further east there. 

SC Well, I'm not absolutely sure - master 

alarm on the accumulator - 

CAPCOM Roger, we copy. 

SC I can't make out Japan specifically yet, 

but it's clearly past Korea and by inspection it looks like 
it would be also past Japan by now, the trailing edge of the front 
However, the circulation center on further northeast maybe 
effecting the Hokkaido, as I said. 

CAPCOM Roger. Like I said, the front on the 

old prog for yesterday showed that front on the other side 
of Japan, so it moved across pretty well. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 22:19 GET 22:44 MC 136/2 

SC As I recall they had a tropical storm 

called Sally that went into (garble) a few days ago and so 
I suspect this new one that I think I see between Borneo and 
Viet Nam maybe something else, a new depression or I may be 
fooled by it. Mainland China, Bob, was - on the last pass here, 
I can't see the Earth now, but mainland China looked like it 
was clear as far as I could see but there might be another front 
quiet a ways inland, but that gets right at the LM and I can't 
tell, but Korea, Yellow Sea and the regions of China, south of 
there, Shanghai, Nan King and those places look as though they 
are quiet clear today. I'll check that again next time around. 

CAPCOM Roger. And, Jack, we are ready to terminate 

the charge on battery B and start the charge on battery A. 

SC Okay, that should work.

CAPCOM That's affirm, Jack. 

CAPCOM Go ahead, Jack, you're coming in very weak. 

SC Well, I didn't intend to be transmitting. 

We were just discussing the battery vent and things. We may have 
missed something in the dump checklist. We'll check it out. 

CAPCOM Roger, we don't think so. We j-ust thought 

maybe you might have read it earlier. 

SC Oh, yeah, you want the battery vent it 

should be closed now, right? 

CAPCOM Okay, stand by, Jack. 

SC Okay, Ron says it ought to be open. 

CAPCOM That's affirm. It should be open. 

SC Let me j us t check - 

CAPCOM There's no question about that. It should 

b e open . 

SC Okay, it's open. 

CAPCOM There's no problem, Jack. It should be 

open but the value appears a bit low to us and we'd like to 
read it again before you go to sleep or we may want to close it. 
And the nominal reading would be 1.7 on that. 

SC (garble) 

SC Okay, we closed it when we were doing all 

our dumping some time back and neglected to open it again. So, 
it was closed when I gave you the reading and it has been closed 
during some 2 hours anyway. I haven't figured out how long. 

CAPCOM Okay, we copy that. Jack, would you mind 

opening the vent and watching the system meter concurrently 
with it? 

SC Standby. Well, it's closednow and it's 

still reading what it - .6. Do you want us to open it again? 
CAP COM Rog- Open the vent and - 

SC I mean, it's open now. I'm sorry, Bob. It 

is now open and reading .6. It read .6 when it was closed. 
CAPCOM Okay, just leave it open now. 

S C Ok ay . 

CAPCOM And we'll want to still check it prior to 

your sleep period. 

SC Okay. Okay, Bob, a little update on the 

coast of Asia. It looks like some residual cloudiness would be 
affecting the F us an region of Korea. And, also, that's residual 
after the frontal passage. And it looks like maybe Shanghai, 
after all, may have some storms associated with It but it's 
really hard to pick out exactly - the exact coast line of Asia, 
but I - there are some clouds in the Yellow Sea behind the 
front. Look like they might be possibly some high cirrus is all. 

CAPCOM Jack, do you still see that storm that you 

said was sitting between Guam and Borneo and that area?

the pre-sleep checklist. Here's one more readout for you. Battery C 
is 37.0; Pyro Bat A is 37.2; Pyro Bat B is 37.2; RCS A 95; Bravo 94; 
Charlie 94; Delta is 96. 

CAPCOM Roger, we copy that. And if you started - we 

don't want you to reinitialize the PTC until about 2400 on the 1

SC Okay. We're - we're just getting a little 

ahead - we - took us longer last night on the pre-sleep than we 
expected. We're trying to work it out again. 

CAPCOM Yeah. We don't to - we want to terminate the 

waste stowage vent at that time, because we think that that vent Is 
what's contributing to our PIC.

ready to go to sleep yet, but we're just moving ahead.

CAPCOM Roger. We're standing by. 

SC Okay, the fans are off. 

CAPCOM Roger. 

PA0 This is Apollo Control at 23 hours 25 minutes. 

The crew has completed realigning the inertial measurement platform- 
the platform used as a stable reference. The spacecraft guidance 
and control system uses it as a reference in determining its own 
attitude. They've also been charging the two entry batteries that 
are used during peak electrical loads of liftoff, and then are 
recharged during the translunar coast when the fuel cells are 
producing a surplus of electrical energy. They recharged one of 
those two batteries and are in the process of recharging the second 
one at this time. And you heard the crew describe going into their 
pre-sleep checklist and getting things aboard the spacecraft 
configured for the sleep period, which is scheduled to begin at 
25 hours ground elapsed time or a little more than 1-1/2 hours from 
now. Apollo 17 at this time is 96 244 nautical miles from Earth, 
traveling at 5 264 feet per second. And all spacecraft systems 
continue to function almost perfectly as planned. A little while 
ago the lunar module officer - control officer - confirmed from 
telemetry what Gene Ce rn an was reporting visually out the window 
and that is that the lunar module appears to be in very good 
shape. Of course we have a limited number of telemetry readings 
on the LM at this point. But one of them that we do have gives 
us an indication of the integrity or tightness of the LM cabins. 
We can see that in the amount of pressure decaying. It appears 
to be a very tight vehicle. 

CAP COM Say, Jack, we got a request in here from our 

ARIA friends. 

S C Go ahead. 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 22:52 GET 23:19 MC 138/2 

CAPCOM They were just wondering if your looking out 

that way, if you could give them some sort of update of what the 
weather in the Wake I s 1 an d-Kwa j ale in - the south of the Wake area 
look like. 

SC Okay. Let me work on that one. 

CAPCOM Okay. You're going to earn your American 

meteorological society badge pretty quick. 

SC Okay. Let me get the monocular and we'll look 

at Wake Island. I miss having all those nice latitude-longitude 
lines on the globe. 

CAP COM Yes sir. 

p A0 The ARIA friends that CAPCOM, Robert Overmile, 

is refering to, are the crews of the Apollo Range Instrumented 
Aircraft used in supplementing the manned spaceflight network 
coverage. They'll be leaving from Patrick Airforce Base prior 
to the end of the mission and flying into the Wake Island area to 
be on station during Apollo 17 's reentry and splashdown. 

sc Okay, Bob, I'll probably have to work on this 

one a little more, but - but it looks like around Wake, or in the 
vicinity of the Kwajalein' s and north of Wake, about all you have 
is a lot of cloudiness although - and in a generally - over wide part 
of that Pacific, I'm talking about 15 or 20 degrees of longitude 
and latitude, there's a - roughly a clock a - clockwise circulation 
pattern, but the clouds do not look very dense or concentrated in any 
one area. And leading off to the southeast from that general 
cloud mass there cyclonic - anti cyclonic cloud mass is a - is one 
of the old fronts - or at least one of the old linear cloud patterns 
that extends down into the south Pacific. 

CAP COM Roger, Jack. I'm sure that the ARIA troups are 

listening down at Patrick and got all of that. 

sc Well my guess is, Bob, and it's purely a guess, 

is that there probably - if they were out there right now, would be 
experiencing an intermediate layer of clouds with scattered showers. 
And a not too strongly developed circulation system, so I can't predict 
the winds. But I wouldn't expect them to be anything - anything what 
might be down - associated with the remnants of the tropical depression 
Thresa. Now that Thresa - what's left of it, if I'm correct in 
picking it out there, probably is moving in that direction, although 
it looks weak enough that right now I don't think it would be any 
big problem. It may, in fact, go south of there. 

CAP COM Roger. The prog I got in my hand for three hour 

old weather has Thresa located just about in the Manila area. Did 
you concur with that or do you think it passed the Philippines? 

sc Well, I don't - Manila's clear. The only thing 

approaching near Manila is this other storm center that is now north 
of Borneo. And to the east of Manila it's clear all the way over 
to this little cloud mass that I was guessing that might be Thresa. 

CAP COM Roger. All I say, this is 3 hours old - 

APOLLO 17 MISSION COMMENTARY 12/7/72 CST 22:52 GET 23:19 MC 138/3 

SC "hat's about - I gave Gene Kranz the 

coordinates on it. You can look it up. Those are pretty good 
coordinates for that cloud mass. Now whether that's really Thresa 
or not I don't know. 

CAPCOM We got one thing with - for the last couple of 

hours here, we've been gecting high b i L rata data through our new 
facility - a new facility at Tidbinbilla. Tidbinbilla is 
through a 210 dish and they're covering the first - 

SC Wake in the Kwajalein - Marshall Islands, in 

that area, and it doesn't look like a very concentrated weather 
pattern, although it looks like you'll have ceilings in that 
region, and they're overcast ceilings rather than broken. Except 
around the fringes of it. 

CAPCOM Roger. 

SC We'll keep an eye on it of courese. 


APOLLO 17 MISSION COMMENTARY 12/7/72 CST 23:12 GET 23:37 MC 139/1 

CAPCOM Jack, how do you read us now? 

SC You're on clear. 

CAP COM Okay, 17, for the last 2 hours we've 

been getting high bit rate data from a new facility, the 
facility at Kid Ben Villa and they working their first 
Apollo flight ever, you might give them a cheery hello. 

SC Kid Ben Villa, is that correct? 

CAPCOM That's affirmative. It's very close 

to the Honeysuckle Base - 

SC Where is that. 

CAPCOM Very close to Honeysuckle. 

SC Well, how you doing, how you doing 

mights? We certainly appreciate you guys being on the

The crew, at the present time, is stopping the passive thermal 
control mode. They'll be reestablishing it. It had begun 
to diverge a little bit - it had begun to wobble about the 
axis. The concern in going to sleep with that sort of situation 
is that it will wobble through the point at which they would 
have gimbal lock and of course we would wake them up before 
then but in order to avoid having to disturb the crew's sleep 
they'd like to get the passive thermal control very stable, 
so that it will hold up during the entire sleep period. 

SC How do you read?

SC Bob, Jack, your last report for the 

day as the Earth goes past window 5. The first thing I noticed 
was that our zero face point is not nearly as bright on 
the west coast of Australia as it was on the east and it's 
looking right at the coast line now and see no bright spot 
in the center. Also that circulation pattern or tropical 
depression possibly that I saw earlier north of Borneo is 
now even more strongly developed and the tail end of the 
front is searching up toward Japan and it, it really looks 
like a humdinger from here. Beautiful circulation pattern 
and very concentrated. And it is now east of Viet Nam and 
again between Viet Nam and the Island of Luzon.

us our weather report - you'll be too far out but we'll probably 
be starting to hear from the Moon, huh? 

SC We're not going to see much of the Moon,

this day I think I acclimated and I really feel good. I've been 
eating a lot better and I'm not - the only thing I ever really 
felt was a slight headache. It really - not the fullness of 
the head that people describe, I guess, but just a little head- 
ache. I could have been looking at the Earth too much, I don't 
know . 

CAPCOM Roger, Jack, you've been sounding good. 

SC Oh, actually, I've been feeling fine. Just - 

none of us have felt like eating and that's probably normal and 
everybody's eating more now and we'll start to sleep at night. 

CAP COM Roger. Jack, just a reminder on that 

time for the presleep checklist. It's important to us because 
we can get high bit rate data more.

those remarks about 

talking about something he is very unfamiliar with, 
having a longstanding interest in it, and I think the one 
philosophical point, if any, that comes out of it is that 
somebody, probably three and a half billion years ago or so, 
could have looked at the Earth and described patterns not too 
dissimilar. And, it was within those patterns that life de- 
veloped, and now you see, I think, and obvious to everybody, 
what that life has progressed to doing, and I certainly think 
that all of us feel it has not stopped doing that progression, 
and we'll probably see it doing things that even you and I 
can't imagine them doing. I certainly hope so. 
CAPCOM Roger, Jack, we concur. 

sc Bob, you always wish that you had a poet 

aboard one of these missions so he could describe things that 
we're seeing and looking at and feeling in terms that might - 
might transmit at least a part of that feeling to everybody in 
the World. Unfortunately, that's not the case, but he - he 
certainly couldn't look at that fragile blue globe and not 
think about the ancient sails of life that are crossing its 
path and wonder ahead to the - up to the present, to the modern 
sails of life that are represented by men that developed out of 
that life that are sitting there next to you and that

the country in all sorts of different guises and working towards 
the same end and that is to put that life farther into the 
Universe. I certainly hope that some day in the not too distant 
future, the guy can fly who can express these things. 

CAPCOM Roger, Jack, you're doing a pretty good job 

expressing them. Jack, Houston. 

SC Go ahead. 

CAP COM Alright, Jack, we'd like to go to select 

OMNI Bravo and stow the high gain in the normal stowage. It 
is customary we do not use the high gain for PTC going TLC. 

SC Okay, Bob, I'm sorry but the checklist 

indicated that you do all go back to OMNI Bravo. 

CAPCOM Rog. It's probably ambiguous if you end 

up going on the checklist up to the top of 128, it shows you 
where you want OMNI Bravo. 

SC Ambiguous is the best word I can think of 

for it. 

CAPCOM Say again, Jack. 

SC Ambiguous is the best word I can think of 

for it. 

CAPCOM Rog, I concur. I should have probably 

called you earlier and just pointed out on the flight plan 
where it says presleep checklist and then there's the word 
COMM and it says OMNI and that leads you into the checklist 
and makes sure you use the OMNI setup for the sleep configura- 
ti on . 

SC Ho, ho, ho. Tricky fellows. I guess you're 


CAPCOM Yes, normally we don't SIM PTCs, TLCs, and 

TECs very often, that's for sure.

line up until we get an indication that the Lunar Module Pilot 
is asleep. The other 2 crewmen are asleep. At 25 hours 
23 minutes, this is Mission Control, Houston. 

SC Okay, Bob. I think I'll hit the hay. 

How does everything look to you?

Apollo 17 is 113 208 nautical miles from Earth. Traveling at a 
speed at 45 79 feet per second. In 36 minutes, Apollo 17 will 
reach the half-way point to the Moon in terms of distance, at a 
ground elapsed time of 30 hours 3 minutes no seconds. Apollo 17 
will be 114 787 nautical miles from both the Moon and the Earth. 
3 hours 32 minutes remaining in the crew's sleep period. At 
29 hours 27 minutes, this is mission control Houston. 


APOLLO 17 MISSION COMMENTARY 12/8/72 GET 30:27 CST 0600 MC 149/1 

PA0 This is Apollo Control at 30 hours 27 min-

in distance in its journey to the Moon. At that time in the 
elapsed time of 30 hours 3 minutes, it was 114 787 nautical 
miles from both the Earth and the Moon. Its velocity at that 
time was 4 522 feet per second. At this time, Apollo 17' s 
distance is 115 842 nautical miles from the earth. Velocity is 

4 483 feet per second. Midcourse correction number 2 will be 
performed at an elapsed time of 35 hours 30 minutes. That's 

5 hours 1 minute from now. It will be a 10.5 foot per second 
burn. The crew still has 2 hours and 31 minutes remaining in 
the sleep period. At 30 hours 28 minutes this is Mission 
Control Houston.

PAO This Is Apollo Control at 31 hours 12 min- 

utes. Apollo 17 is now 117 746 nautical miles from Earth, 
traveling at a speed of 4415 feet per second. Flight Director, 
Pete Frank, and his orange team of flight controllers will 
hand over Mission Control duties to Jerry Griffin's gold team 
of flight controllers in about 15 minutes at 7 A.M. central 
standard time. Each of the departing controllers is now 
briefing his relief. There will be no change of shift news 
conference. The orange team will double back after 1 shift, 
returning to the Control Center at 5 P.M. today to get back 
on a schedule which will put them on the EVA shift. To sum- 
marize the shift now ending, the crew began rest period at 
25 hours elapsed time. Each crewman took a sleeping pill and 
Jack Schmitt reported that Gene Cernan and Ron Evans were 
asleep shortly after the crew configured the spacecraft for 
their rest period. However, Jack Schmitt, who was the duty 
man to wear the head set and the bio-medical harness during 
this rest period, seemed almost reluctant to surrender his 
view of the earth to sleep. At 100 000 nautical miles from 
the Earth he broadcast a weather forecast, then indulged in a 
bit of philosophy as he gazed from his window, about mankind's 
achievements. He remarked that from his vantage point the 
Earth probably looks the same now as it did at the dawn of man. 
Apollo 17 reached the halfway point to the Moon at an elapsed 
time of 30 hours 3 minutes. At that time it was 114 787 nautical 
miles from both the Earth and the Moon. Spacecraft's systems 
are continuing to perform well and the CAPCOM astronaut 
Bob Parker plans to awaken the crew at 33 hours elapsed time, 
that's 1 hour 44 minutes from now. Midcourse correction number 2 
will be performed at an elapsed time of 35 hours 30 minutes, 
4 hours and 14 minutes from now. Present indications are that 
it will be a 10 and 1/2 foot per second burn. The latest pre- 
diction on the S-IVB is that it will impact the Moon at an 
elapsed time of 86 hours 58 minutes 23 seconds. Coordinates 
of the impact location presently predict it 6.73 degrees south, 
9.7 degrees west. The impact time and the coordinates are 
likely to chang prior to the impact itself and continued 
tracking of the S-IVB will be perfoj^d. At 31 hours 16 minutes, 
this is Mission Control, Houston. 


APOLLO 17 MISSION COMMENTARY, 12/8/72, CST 08:00, GET 32:27, MC-151/1 

PA0 This is Apollo Control at 32 hours 27 minutes 

ground elapsed time. The Mission of Apollo 17, which at this 
moment is 120 887 nautical miles out from Earth, velocity has 
continued to decrease to 4305 feet per second. Slightly over 
a half hour remaining until spacecraft communicator Robert Parker 
gives the crew a wakeup call. And a relatively busy day ahead 
with midcourse correction, - midcourse correction maneuver #2 at 
35:30 ground elapsed time, a 10-1/2-foot per second posigrade 
maneuver which will raise the trajectory slightly from an impact 
trajectory with a minus pericynthion at the Moon, raise it to about 
60 nautical miles above the surface. Latest numbers on the S-IVB 
impact predictions is for impact to take place at the ground 
elapsed time of 865823 at 6.7 degrees south latitude by 9.7 degrees 
west longitude. The gold team of flight controllers have settled 
in for a 10-hour day here in Mission Control, which in addition 
to the midcourse correction burn, includes the first manning of 
the lunar module, first checkout, which begins at about 40 hours. 
They start actually, at 39:30 getting the probe and drogue removed 
from the tunnel, going into the lunar module. We'll come back up 
live with the air-ground when the first call is made to the crew 
by the spacecraft communicator. And at 32:29, this is Apollo 
Con t rol .

PAO Th is is Apollo Control, 32 hours 58 minutes 

ground elapsed time into the Mission of Apollo 17. Almost 2 minutes 
remaining until the first wakeup call is made to the Crew of 
Apollo 17 by sp acecraft communicator Robert Parker. Parker is 
joined this morning by Apollo 17 backup Commander John Young at 
the CAPCOM console, and it appears that Parker's releif CAPCOM 
Gordo Fullerton, just walked in the door and likely will relieve 
Parker in the day's duties of getting off midcourse correction #2 
burn and the first housekeeping venture into the lunar module. 
Apollo 17 is now 122 186 nautical miles out from the Earth,

CAPCOM Yes we are, go ahead. 

SC Africa, looks in pretty good shape, there 

except for an area probably around Zambia and Rhodesia in the 
tropical convergence zone there where it looks pretty cloudy 
and probably quite rainy. There's a very strong circulation 
pattern and presumably a storm just off the coast of northwest 
Africa, very spectacular spiral formation of clouds in a cyclone 
development. It looks like there are probably 2 fairly weak cyclones - 
southern hemisphere cyclones in the south Atlantic. One, south- 
west of the Cape of Good Hope and the other about due west of 
the Balkan Islands, maybe a little bit north of that. South 
America looks to be in quite good shape weather-wise, except 
possibly Uruguay and maybe northern Argentina which appear to 
have a - at least some fairly thick clouds there, although no 
strong circulation associated with this. (Noisy interference 
covers some transmission). 

is a- 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 9:20 GET 33:48 156/1 

CAPCOM Okay, Jack. We got all that up to 

Argentina, then the OMNI switch kind of cut you off. 

CAP COM Jack, we got at least the first part 

of your weather report from up through the clouds in Argen- 
tina and then the switch in OMNI's cut you out. 

SC Okay, that was about it, Gordie, that's - 

talk to you some more later on it . I guess the main thing 
I need now are your cons ummables . 

CAPCOM Okay, by the way, you were looking back 

from more than half way to the moon, you're about 125 000 
out now. On the con s ummab le s , the RCS is running at 1.3 per 
cent over the flight plan line. On the 02, tanks 2 and 3 
are right on the line and tank 1 is about 4 per cent below 
the line, but it's been there all the way since launch, that 
same bias on tank 1. On the hydrogen, tanks 1 and 3 are 
right on the line, tank 2 is about 3 percent above the line. 
All in all, you're looking real good consummable-wise . 

SC Okay, that's hardly worth writing down 

I guess. That's the way we like to see it. 

CAPCOM Same here. 

CAPCOM The only other thing I have in the way 

of updates is a P IPA bias update. You can load it yourself 
or we can load it when we come up with the uplink prior to 
the burn - your choice, and then we'll have an update to 
the erasable load update and a supplement to correspond with that 
bias update. 

SC Gordie, why don't you go ahead and load 

it yourself when you send up the vector. 

CAPCOM Okay, and I'll give you the update for 

the supplement. It's on 1-43 whenever it's convenient. 

SC Okay, Jacks getting that out. I ran 

another PIPA bias at minus 100 and it confirmed the first 
one. It ended up at 99.2. 

CAPCOM Roger. 

SC Go ahead with your update on 1-43, 


CAPCOM Okay, it's in the load A, and the 

octal ID of 03, which now reads 77252, change that to 77655. 
SC Did you copy, Gordie? 

CAPCOM I didn't copy your readback, no. 

SC Okay, 30603 and alpha 77655. 

CAPCOM That's right. 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 09:30 GET 33:59 MC-157/1 

SC Gordy, how do you read? 

CAPCOM Loud and clear. 

SC Okay, for the reference on those figures, at 

least for the LMP , I think I'm probably putting 8 or 9 ounces of 
water in the citrus drinks and those kind of things rather than 
7, which has probably upped my water intake some.

probably goes - goes for Ron and probably Gene also.

CAPCOM Okay, front page first. In Paris Henry 

Kissinger met for 30 minutes this morning with French President 
Georges Pompidou at the Elysee Palace just hours before his 
scheduled conference with North Vietnamese Polit Bureau member 
Le Due Tho. North Vietnamese spokesman accused Kissinger of 
attempting to force a peace settlement by threatening further 
escalation of the war. As both U.S. and North Vietnamese negoti- 
ators expressed disappointment at the continued deadlock, Chief 
American delegate William J. Porter traveled to Brussels to 
brief Secretary of State William B. Rogers. Rogers will return 
later today from the NATO Conference of Ministers. This one is 
datelined Brussels. Diplomatic sources indicated today that 
NATO allies will request negotiation with the Soviet Union and 
its allies on mutual troop reductions in central Europe. Explora- 
tory talks is expected to begin by January 31, with full scale 
negotiations to follow sometime next fall. In Kansas City, 
vital life signs for Harry S. Truman appeared to have stabilized. 
But the 88 year old former President remains on the critical 
list at Kansas City's Research Hospital. Truman is suffering 
from lung congestion and heart weakness. In Argentina, aids to 
popular Argentina politician Juan Peron said that Peron will 
refuse the nomination to the presidency of Argentina, and will 
return to exile during the coming week. And on the sports page, 
Rice coach AI Conover is expected to reveal sometime today his 
decision to either remain at Rice as head coach or move to his 
alma mater Wake Forest in a similar position. The Owl head 
coach has said that he has been offered the job and promises 
a "yes" or "no" decision today. There is some speculation that 
head coach Joe Patemo of Penn State may move to a head coaching 
job in the Pros next year. Paterno is busy preparing his Nittnay 
Lions for a Sugar Bowl meeting with Oklahoma and is refusing to 
discuss the matter until after the game. Locally, the state 
high school football playouts -

ground elapsed time. Apollo 17 spacecraft, should at this time 
be coming out of the passive thermal-control mode and getting into 
the proper attitude for the midcourse correction burn #2, which 
is some 31 minutes and 23 seconds from now. Apollo 17 presently 
126 988 miles from the Earth traveling at velocity of 4098 feet 
per second. The midcourse correction burn #2 with an ignition 
time 35:29:59.1 has a velocity change in the posigrade direction of 
10.6 feet per second, which for the service propulsion system 
engine is a BURP lasting 1.58 seconds. Purpose of this burn is 
to raise the pericynthion from an impact trajectory as it stands 
now, to one with a clearance over the Moon of some 53 nautical 
miles which will become the pericynthion of Lunar Orbit. Standing 
by on air-ground 1 at 34:59 this is Apollo Control.

OMNI Charlie will probably work better. 

SC Okay, Gordy, we got your OMNI Charlie 


CAP COM Okay, Locked on. 

SC Gordy, for your information we have our 

LM transfer items in the jettison bag ready to go over and we're 
pretty well squared away on the, all the command module stowage 
now with minor exceptions. 


CAPCOM America, Houston we'd like you to go ahead 

and get on the high gain again since, stop it just wondering 
around aimlessly, and how does the Earth look now? 

SC Sorry, Gordy to be so slow, Earth looks great ! 

and we'll get the high gain up. 


SC Houston, 17, are you reading? 

CAPCOM Go ahead, loud and clear. 

SC Okay, Gordy, going from South to North 

on Noon time, at least our Noon time weather, looks like there 
is a fairly strong mass of polar air moving from the Southwest up 
towards Tierra Del Fuego. It's mixed with some cloudiness that 
extends from that area all the way down to the Antartic ice 
shelf. But looks like some pretty good movment patterns from the 
southwest north northeast. No strong weather waves or cyclone 
development on that yet although one may be picking up about 
half way between Tierra Del Fuego and the coast of Antartica. 
The - where the front, or at least the cloud masses curve from 
an east west direction to an almost due south direction. 
Most of South America still looks like pretty good weather. 
There is cloudiness along the Andian Ridge and also in the 
Amazon Basin, stretching from the eastern coast of South 
America on up about, oh, two-thirds the way towards Central 
America. It doesn't look like frontal weather there. It's 
probably tropical convergence weather. Now there is this - 
still this small moderately developed cyclone pattern that's hanging 
pretty much over Buenos Aires now, I think, Uraguay and 
Buenos Aires. I think I mentioned that earlier in the day, 
and that still is there and I suspect those folks are getting 
a fair amount of weather out of it. 

CAPCOM Roger. 

SC Except for scattered clouds, Central 

America and Mexico for the most part are clear. As is most 
of the Caribbean Islands. Cuba and the others all look like 
they have pretty good weather. There's a little clouds off 
- cloud pattern off to the east of those Islands but doesn't 
look like any major weather in that area. The eastern half 
and midwest of the United States is completely cloud covered 
by now. There, however, the - extending from Mexico to Senora 

APOLLO 17 MISSION COMMENTARY 12/8/72 37:58 GET 13:30 CST MC-174/2 

and up into Arizona and New Mexico and possibly as far north 
as Colorado, is a clear band; but then there is more cloudiness 
to the north of that. The Pacific regions west of - the west 
coast of the United States is cloudy at least west of Southern 
California. I can not see Baja, so that cloudiness extends 
down south of - into Baja, California. I see no strong new 
frontal patterns; although I'm looking right across the LM at 
the Earth now. There may be one that would be lying maybe 
across Northern California and into Colorado. With a little 
clear area ahead of it, possibly in Kansas, but then into this 
solid bank of clouds that stretches from Brownsville at 
least clear up to - along the Gulf Coast across the panhandle 
of Florida, up the East Coast into, on out Nova Scotia, I'm 
sure. Florida is clear. Florida, let's see, the peninsula 
portion of Florida, it looks very clear and some of the deep 
turquoise green water to the south and southeast of that area 
are very obvious at this time. 


APOLLO 17 MISSION COMMENTARY 12/8/72 GET 37:25 CST 13:57 MC175/1 

Roger, Jack. I'm following along on the satellite 

your same vantage point, 
you're describing, 
analysis charts of the 


weather picture here that's taken from about 
and although nowhere near the detail that 
SC Have you seen today's 

United States or North America? 

CAP COM No I haven't. I just 

men and a lot of other people around here, 
weather reports with great interest. 

Yes. Does that mean they're right or 
You've got the better view by far. 
That doesn't prove much. Okay, Gordy 
that's a pretty healthy front. I don't know 
be cloudy and bad today. Is that right? 

Yes. We've got about a half mile vis 

told Jack 
too, are 

that the weather- 
following your 

w r ong ; 

, I'm, I 

and drizly 



suspect that 
weather must 

rain . 

sc Okay. Well, I suspect comparable weather extends 

all the way across the eastern United States. That looks like awful 
dense clouds, although there's no obvious frontal pattern. It just 
stretches from the Midwest to the East Coast. And, also, there's no 
good indication of stratification of those clouds, as if they'd be 
fairly thick up into the serious level. 

CAP COM Roger, Jack. 

sc Looks like Arizona, New Mexico, and northern 

Sonora probably has 1 band of high cirrus, but other than that, 
probably a beautiful day out in that area. There's some transverse 
cloud patterns over the Mississippi/Alabama area. Suggest maybe that 
the jet stream may be just north of that region. But otherwise, 
there's now good indication of jet stream 



SC Gordy, there is one minor 

possibly just about over Puerto Rico or maybe 
island. No strong circulation patterns, 
of a cyclone development. Might be just

I do, just now, got a copy of the services chart for

Texas northeastward up through Tennessee and Virginia, and another 
one sort of parallel to it. But, this way southward from Louisiana 
along the Gulf Coast across northern Florida and on out into the 
Atlantic, and I guess the two are kind of blending together to make 
that irregular mass of clouds you mentioned. 

sc Okay, Gordy, if I'd been a little more observant 

I could see that there was a little bit, looks like a decrease 
le ast the thickness of the clouds, vertical thickness 

b etween 

in at 

APOLLO 17 MISSION COMMENTARY 12/8/72 GET 37:25 CST 13:57 MC175/2 

sc two areas you just mentioned. So, there is 

some indication of those two fronts. Although, they are contribut- 
ing to a general weather pattern in the eastern United States. 


sc 1 think with a little experience in this busi- 

ness, you might have picked those two out of that mass, but it's 
not immediately obvious. 

CAP COM Roger. 

sc Y °u got anything on there coming in from the 

northwest now, say up in Wyoming or Colorado? 

CAPCOM The way it's drawn on this surface charts shows 

that northern front that I mentioned just now, sort of curving on 
up through Central Colorado, and then bending westward toward, through 
Utah. That's about the only other frontal activity. There's one, 
probably dry front, then a short one through Central Arizona. And 
s outhe rn Ut ah . 

sc Okay, well that makes sense. That would match 

with that what I was thinking was high cirrus in Arizona. And 
also I can see how you could bend, that's the northern front 
up through Colorado and then back westward to explain the patterns 
we're seeing in the clear areas south of that. 


sc Gordy, the zero phase point now is off the coast 

of Chile and Equador, oh, maybe, 10 or 15 degrees of longitude, and 
it is fairly dull. It does not seem to indicate any great amount 
of choppiness or wave action in that area. 

CAP COM Roger. 

Sc An d about 15 minutes ago, Gordy, I took 2 more 

Hasselblad shots of the Earth. 
CAP COM Okay. 

SC And also, Houston, frame number, let's see, 

that's 16 and 17 were taken of the Earth about 15 minutes ago, too. 
And it's magazine Sierra, Sierra. 

CAPCOM Okay, Ron, we copy that. 

sc Gordy, with respect to the ice pack off the 

coast of Antartica, it's difficult to distinguish pack ice from 
clouds, in general. However, the clouds seem to pick up reflection 
patterns with respect to the Sun, and using that and some shadows 
below as the criteria, it looks as though the pack ice in the 
South Atlantic would extend to a latitude almost comparable to that 
of Tierra Del Fuego. I don't know whether that, that's reasonable 
or not . 

CAPCOM Okay, I don't either, but maybe someone who's 

more of an expert can clear up your question on that. Ill let you 
know . 

sc Yes, now to the southwest of Tierra Del Fuego 

there's a, looks like a small cyclone developing, clockwise rotation, 
just off the edge of the pack ice, and, but it does not seem to be 
closely associated with the frontal activity that I mentioned when I 
s t arte d. 

APOLLO 17 MISSION COMMENTARY 12/8/72 GET 37:25 CST 13:57 MC175/3 

SC out speaking at this particular time. 

CAPCOM Roger. 

SC There is another one, maybe a front, a little 

bit ahead of that cyclone, that's now extending north-south, starts 
in the pack ice area and extends up, oh about halfway from there 
to Buenos Aires, in the direction of Buenos Aires. 


APOLLO 17 MISSION COMMENTARY 12/8/72 38:37 GET 14:10 CS T MC-176/1 

SC Buenos Aires. It doesn't look like a 

very major mass of air, or frontal system. It may develop into 
something over the next couple days though. 

CAP COM Okay. 

SC And centered, Gordy, at about 45 south, and 

say 30 west, there is another cyclone area that's ahead of 
the last one I talked about. That doesn't look, I think I 
talked about it yesterday, still does not look too strong, 
although, the clouds as I recall, the cloud cover is some- 
what more well developed and circulation patterns seem to 
be better developed. It may be an intensifying storm over 
what we saw yesterday. 

CAP COM Roger. 

SC I can not see that it is associated with 

any clear frontal activity however. 
CAP COM Okay. 

SC That, I presume, should be migrating 

in the direction of the southeast coast of Africa, so we'll 
keep an eye on it. 


SC That reminds me, did you get any informa- 

tion on the, that, what looked like a very strong concentrated 
typhoon or hurricane in the south Pacific between Borneo and 
the Philippines? 

CAPCOM Let me check and see what we got on that. 

I wasn't here when you first talked about it evidently. 

SC Well, it was one that they didn't seem 

to be carrying and it looked extremely well developed from 
h ere . 

SC Gordy, yesterday that one, the one I'm 

speaking of was centered at about 15 north and 117 east. 

CAPCOM Okay, I've been informed that the satellite 

people are carrying that one now. I'm not sure whether they 
had seen it before or until after you did. But they are aware 
of it now, and are tracking it. 

SC Well, we're not competing. They just 

didn't have any information for me on it yesterday. We'll 
probably be able to see that again late this afternoon. 

CAPCOM Okay, the one that you just gave the 

coordinates on, does have a name, Therese. Hurricane Therese. 
And, so the other one must be the, must not have a name. 

SC Okay, now which one has - is Therese. 

CAPCOM The one you just - the coordinates you 

gave almost exactly pinpointed Therese. 

SC Okay, that's near the Philippines. 

CAPCOM That's affirmative. Between there and 


APOLLO 17 MISSION COMMENTARY 12/8/72 38: 37 GET 14 : 10 CST MC-176/2 

SC Okay, well, then that sounds like that's 

an up to date position. It has relatively little movement 
since yesterday. 

CAPCOM Rog. They show it moving just very slightly 


SC Okay. Are they carrying anything south 

of Guam now, that we talked about yesterday? 

CAP COM Ah, take a minute to get something on that. 

They don't have a current map showing anything in Guam right 
n ow . 

SC And we also had a storm developing south 

of, or southwest of New Zealand. Might look at that one too. 
CAP COM Okay. 

CAPCOM Jack, are you making these observations 

through the monocular? 

SC Ah, yes sir. Although most of them, well 

at this distance, Gordy,* the circulation, the detailed circula- 
tion patterns to say what is a cyclone and what isn't, are not 
visible to the naked eye. At least not to mine. 


SC The major frontal patterns are however. 

CAPCOM Jack, that disturb ance you mentioned near 

Guam isn't being carried on the current chart here as anything 
significant. They do show some cloudiness north of the tropical 
convergence zone, but, just that. 

SC Okay, well, I had a feeling that what I 

was seeing yesterday might of just been the remnants of Therese, 
which I think went down into that area a couple days ago. It 
was not a very well developed system, but did seem to be 
isolated from the other cloudiness that I would of put into 
the tropical convergence zone. That was between Wake and the 
Kw aj aleins . 

CAPCOM Roger. 

SC Gordy, let me try to give you a discription 

of something that is a little bit unusual than what we've been 
seeing. The, there's an axis that runs from, say the outer 
portion of the Ross Ice Shelf along the, and just off the coast 
of Antartica, then bends up so that it would pass just to the 
east of Tierra Del Fuego and then continues on that heading so 
that it would intersect the far east coast of South America 
if it continues. Now along that axis the, what appear to be 
multiple frontal patterns, or at least linear cloud bands, 
bend very sharply and change from a heading that roughly parallels the 
axis around the one that is roughly north-south. And some 
of the frontal direction changes that I gave you earlier, down in 
that area are also bent around that axis. 


SC And there isn't, oh, there's probably 

a dozen if you tried to pull 'em out cloud band between the 
Ross Sea and Tierra Del Fuego that bend around the same axis. 

APOLLO 17 MISSION COMMENTARY 12/8/72 38:37 GET 14:10 CST MC-176/3 
SC Quite striking. 

CAPCOM Roger. 

SC Now there's some indications to me at 

any rate, that the jet stream in that area may be essentially 
east-west, oh, maybe 20 degrees of latitude north of the Ross Sea 
and then bends down very sharply so that it intersects the, or 
approaches the Antarctic Ice Shelf to the east of the Ross Sea 
and then maybe it bends up and forms the axis I just described that 
is causing that bending of the cloud pattern. 

CAPCOM Okay. Sounds like a good theory. 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 14:25 GET 38:52 MC177/1 

SC — there's a linear clear area in that area 

north of the Ross Sea that -- and to the north of that is a sharply 
defined front that I talked about earlier. And, then both -- that 
front continues, the clear area is cut off by the axis that I 
described, the cloud axis. 

CAPCOM Roger. 

SC Now, that should show up real well on the 

250 millimeter pictures we took — 

SC Gordie, I'm back looking at zero phase, and 

now, apparently the exact zero phase was partially obscured by a 
cloud pattern earlier. Now, when I -- there is a very, very small 
bright spot in the center of the zero phase area. Nothing compar- 
able to what I described off the coast of Australia yesterday, but 
an extremely small spot. I suspect that the size of your bright 
spot in zero phase has some direct or indirect, at any rate, 
relationship to (garble). 

CAPCOM Roger. 

sc Gordie, as you might expect, the whole coastline 

of Chile -- or all of Chile, practically, is clear, beautifully ex- 
posed to us here, in particular the Atacama Desert, which is 
noted for that particular characteristic. And, at least among 
geologists it is. And, the coast of Peru is also clear with clouds 
following the Andean Ridge, probably the -- certainly the coast 
side of the Andean Ridge. Lima ought to be enjoying a very nice 
day today. The Ecuador, however, looks like it might have a little 
more cloudy weather, although it doesn't look like any major storm 
activity . 

CAPCOM Roger. 

CAPCOM America, Houston. We have a couple of words 

here on medications. Is everyone listening? 

SC Yeah, we're on, Gordo. Go ahead. 

CAPCOM Okay, Gene, you mentioned taking a nausea pill 

for some gas yesterday, and we were looking into some of the side 
effects. You definitely don't want to use that particular pill 
for gas. One of the side effects is that it is an appetite de- 
pressor, and there are some pills loaded in A7 along with the vita- 
min pills specifically for the purpose of eliminating gas. We 
would appreciate it if you'd give us a call in advance prior to 
taking any medication except the Seconal and aspirin. Over. 

SC Okay, Gordie, will do. I was aware that those 

gas-depressors were around. At the time, we couldn't find them in 
A7 , and so I took one of those other things, whatever it is, and 
while you're talking about that, as per the preflight food check, 
gas is very evident, particularly on me, and I think I'm suppress- 
ing it slowly, but is there any problem, or what do you recommend 
on that Mylinol — or Mylicon, or whatever it is? 

APOLLO 17 MISSION COMMENTARY 12/8/72 CSX 14:25 GET 38:52 MC177/2 

CAPCOM Okay, stand by one. 

SC It goes hand-in-han d with the amount 

of gas that I experienced prefllght, 
CAP COM Okay. 

SC And it's the kind of gas — it's the kind 

of gas that just stays in your stomach.

came to when I didn't find it in the system data - hey, I got a 
little bit to tell you about that, oh, those little ones underneath 
the power bun gee. 

CAP COM Okay, go ahead. 

sc Okay, if you look at the docking 

lights, number four up beside of that oh, kind of a (garble) looking 
thing. There is a snowman. In other words, a great big fat thing 
with a head on top of it. And if you consider the fat thing 
with the head on it as a snowman, well then the snowmans head, is 
pointing out a 9:00, on that one. Whereas one that's fully 
cocked and latched over there the snowman's head points up 
at about 11:00. And - okay, there is a lever that comes 
right out of the bottom of the power bungee it looks like, and then 
it comes out of the bottom then left out of that lever is another 
silver slot or silver bar that goes from the lever to the J hook 
with the snowman on it. That particular thing that connects 
the J hook to the lever coming out of the bottom of the bungee is visible 

In other words

SC Putting the cue cards up now and the 

camera by the way, Gordie operated for 2 frames and the 
resolo clean lens looks clean and everything's fine with it. 

CAPCOM Okay, Jack sounds good. 

PAO This is Apollo control. Schmitt and 

Cernan at this time still in the lunar module going through 
the activation and housekeeping chores that are scheduled 
in the flight plan. They entered approximately on time as 
indicated by the flight plan. Meanwhile, here in the control 
center one of the docking collar capture latches is here in the 
control center being examined by flight controllers trying 
to sort out why some of the latches apparently did not fully 
engage during the docking operation. Spacecraft now 
140 451 nautical miles from Earth velocity now is 3 683 feet 
per second. Continuing to stand by on air ground 2 for a 
conservation from the crew of Challenger.

SC The regular type, huh? 

SC Okay, Gordo, on the top of 1-15, we're ready 

to go ahead and transfer the power. We'll give you a call. 
CAP COM Okay, Geno. 

SC Okay, the LM power circuit breaker is in. 

What the -- let me know what you want, okay? Okay, going to OFF, 
RESET. Okay, back on. And, I have to open my (garble) again. 
The pressure's been? I don't know what it is. 

SC Okay, Houston, we got a good transfer. 

CAPCOM Roger. 

SC Got it again by hitting the panel. 

CAP COM Ron, this is Houston. 

SC Yeah, go ahead, Gor. 

CAPCOM Okay, we've got considerable conversation 

going on here about that docking latch, and it's not at all set- 
tled yet. The primary thing we want to guard against is the 
possibility that it is malfunctioning and that we get it latched 
down on the ring and can't unlatch it, and, therefore, have prob- 
lem with undocking, or possibly even prevent it. So, we'd like you 
steer clear of that until we come up with a final solution. No 
experimentation, please. Over. 

SC Okay, I understand. I'll leave them alone. 

And, just one little other bit of information to let you know 
the handle itself is not free at this point to come on back down 
like it's -- you know. Like, if it were fully cocked, the handle 
itself would be free to come back down. It is not free, I did 
not try to put a whole lot of pressure on it, but it's not free. 

CAPCOM Okay. I understand. 

SC Okay, Houston. Glycol pump 2 is on, it's been 

on about a minute, and we've got good talk-backs from batteries 
1 and 4.

SC We don't have a good up link, Gene. I had 

signal strength. And now I don't have any at all. 

SC Okay, Houston, Challenger gave you a call, but 

he does not have any up link signal strength at all. 

CAPCOM Okay, and we'd like him to hold this configura- 

tion right there, until we get things straightened out and we 
understand what the problem is. 

SC Okay, understand hold configuration there. He 

just got about 2.2 on the signal strength. 

CAPCOM Okay, Gene. 

SC And tell them I head their transmission to you. 

Oh, a few minutes ago. I was at zero signal strength and I heard 
their transmission, (garble). One of them. The first time they 
acknowledged, that I was going to do it. 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 16:54 GET 41:20 187/1 

SC Did you shift my hose back? 

CAPCOM Hello Challenger, this is Houston. Do 

you read me? 

SC Okay, Houston I read you. Your weak 

but clear signal strength is fluctuating. When you called 
me it fluctuated down to about 1.6. Over, and 2 now. 

CAP COM Okay, Jack your loud and clear. The 

background noise I've been mentioning although I guess you 
haven't me mention it till now is what we expect in down 
voice (garble) and low bit rate. How have you read this trans- 
mission all the way through, over. 

SC Did he say, say again. Gene, did he say 

say again. I got a little bit - oh he's got three point - 

SC Their not talking to us this time. 

SC What? Okay, Houston, I've got 3.4 on 

the signal strength and try me again. 

CAPCOM Okay, Challenger your coming in loud 

and clear how do you read me, over. 

SC Okay, Houston, I know you tried to trans- 

mit I could just barely tell that. I could see the signal 
strength vary down to three you were modulating appearently, 
but your not getting through to me. 

CAPCOM Okay, Challenger I'm transmitting symul 

now in both S-band frequencies and it sounds to us like for 
some reason when I transmit the uplink signal starts to 
break up. It's just the way you see it over. 

SC Okay, Gordie you're breaking up there. 

Your still modulating but I cannot read you. Would you 
tell America what you said. 

SC Yes, Gordie we read you in America loud 

and clear on that symul. 

CAPCOM Okay, Geno. 

SC Is he talking, Gene? 

SC As soon as he starts trying to talk the 

signal strength drops off about 4 tenths. 

SC I heard him loud and clear one time 

when he called you guys. 

CAPCOM America and Challenger we're going to hand 

over to a different site and try that, (garble) 

SC What else do we have to do, get some 

of these mags stowed?

VOX, I don't know. Since then, you've been able to modulate 
the signal strength with occasional weak words, and then, that 
signal strength was up around 32 where it is now. Then, you 
came in loud and clear with a broadcast. I answered you, you 
said about three words then dropped off completely. And, then 
we changed configuration.

seen here in the way of signal strengths dropping in and out.

for you about those -- about the latch. Good old latch num- 
ber 4 gave us problems I guess, huh? 

CAPCOM America, Houston. 

SC America, go ahead. 

CAPCOM Ron, can you take a look at latch number 4, 

and is the hook back away from the ring approximately one inch, 
as opposed to rubbing against the ring? 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 17:54 GET 42:20 194/1 

SC America, Houston, did you copy my question? 

SC We're going back to air ground one. Okay, 

I heard somebody going to air ground one that time. 

SC Roger, Ron. Got a couple of questions 

on that latch number 4 if you can answer it for me. 

CAPCOM America, Houston. 

CAPCOM America, Houston. We're back with you 

after some site change, over. How do you read? 

SC Okay, loud and clear. How me, Bob? 

CAPCOM Real good, Ron. On that number four 

latch number four is the hook back away from the ring about 
one inch as opposed to resting against the ring. Do you 
have about an inch clearance on that hook right now? 

SC Well, it's about a half inch. 

CAPCOM Okay, understand about a half inch. And 

what position what the latch handle when the hook was first 
moved back, Ron, was it kind of like in a normal stroke back 
or was it just flopping back? 

SC No, when I first looked at it the latch 

handle was - see the hook itself was over the ring when I 
first looked at it. 

CAP COM Rog, we understand that. 

SC The hook was over the ring and the latch 

handle was flush you know it looks just like a normal hooked 
docking latch. 

CAPCOM Roger, understand. 

SC And, Bob, this is Gene. I can confirm 

that it did not fold back easily because I checked it yester- 
day. I checked to see if the hooks were over as well where 
the handles would fold back. But I obviously didn't check 
to see whether that one was seated. But the handle was 
locked . 

CAP COM Roger, understand. And the first thing 

you saw was the depression in the bungee. Is that affirm? 

SC Yes, that's affirm. And the bungee is 

depressed about three eights - three eights to a half of an 
in ch . 

CAPCOM Roger. 

SC You can push the - you can push the hook 

about an inch away from the ring, but the normal just a 
resting position on the thing is about a fingers width or 
a half an inch from the ring. 

CAPCOM Roger, the hook is loose so it flops a 

little bit, you can move it back and forth. Is that affirm? 

SC Yes, I can move it about a half an inch 

to an inch from the edge of the ring. Clearing the edge of 
the docking ring. 

APOLLO 17 MISSION COMMENTARY 12/8/72 CST 17:54 GET 42:20 194/2 

CAPCOM Roger, Ron when you pull the hook - when 

you pull the handle back did you reach and pull the hook back 
with it or did it come back with the handle like a normal 

pull back then. 

SC No, the hook did not come back with the 

handle. The hook did not come back with the handle. Al- 
though when I pulled the handle back to - which is kind of 
a normally uncocked position. And then it wouldn't go any 
farhter you know it wouldn't go any farther. And then the 
latch itself or the hook or the J hook I'll call it the hook. 
I moved it off the docking ring back to this position which 
was about an inch or an half an inch from the docking ring. 
And it stays right there now. And I can't push it up into 
the docking ring at all. Can't push the hook back up to the 
docking ring at all. 

CAPCOM Okay, we copy that. 

CAPCOM Okay, Ron, our plan here is to leave it 

like it is. We're going to think about it tonight and we'd 
like you to j uf t leave it alone, okay? 

SC Okay, sounds good. It'll clear the 

docking ring, no problem. 

SC Houston, America. While Ron is putting 

in the probe and getting the hatch back in I'm going to go 
ahead and maneuver. How does that sound? 

CAP COM That's real fine, Gene.

of shift press conference in 15 minutes, 15 minutes at 
6:15 central time in the small briefing room. Spacecraft 
communicator now is Bob Overmeyer. During this past check- 
out of the lunar module. We've had considerable difficulty 
in some of the communications configurations in the way the 
down links and the uplinks were set up. And some bit of 
difficulty in sorting out just what the nature of the problem 
with one of the docking is. People will be examining this 
through the night and during the checkout of the LM tomorrow 
or additional work in the LM perhaps the thing can be sorted 
out. Apollo 17 presently at 143 562 nautical miles from 
Earth traveling at a velocity of 3 590 feet per second. 
At 4228 and standing by this is Apollo control. 

SC Bob, are you all going to want OMNI or 

high gain on this. 

CAPCOM Stand by. We're all locked on the high 

gain we'd just like you to leave it on high gain. The 
angles you see in the flight plan are in case it breaks

PAO This is Apollo Control at 43 hours 16 min- 

utes. Apollo 17 is 145 178 nautical miles from earth traveling 
at a speed of 3543 feet per second. The crew is now in the 
midst of the heat flow and convection demonstration. This is 
the demonstration designed to provide more exact data on the 
behavior of fluids in a low gravity field. This type of 
investigation is really not possible on Earth where gravity 
determines flow of fluids. In space the flow forces the 
surface tension. There are three test cells involved in this 
demonstration for measuring and observing the fluid flow, 
behavior and the results are recorded with the 16 mm camera 
aboard. We have about 5 minutes worth of tape that accumulated 

during the news 
and then pickup

SC Okay, Houston. The first thing I noticed 

as soon as I opened the flow four turns when it started 
running out a little bit, even without doing the inject. 
Okay, that's because the inject thing was open just a little 
bit. But it's alright. 

CAPCOM Jack, we got it. 

SC Okay, I'll try to squirt some fluid in there 


SC With the fluid inject thing. 

SC Okay, I'm taking it in quite slow. It's 

noted there are quite a few small bubbles coming out with it. 
So far so good. It hasn't overflowed the first capillary ring. 
And it's taken off and it's going by capillary action toward 
the bottom and toward the top. 

CAPCOM Roger, Ron. 

SC Okay, it finally 

around the top and around the bottom 
opposite of the inject port, and now 

across the middle and fill up from the inject port.

about three-eighths of an inch on the left side of the floor. 
Three-eighths of an inch of the annulus all the way around, 
except for the right, oh, say right two-thirds of the floor. 

CAPCOM Roger. And, you can use more than four 

turns if you need them. 

SC Okay, let's go ahead and try to cover up 

the whole floor on the thing before we do it — the bubbles are 
in there. I'm afraid they're going to stay unless they disappear 
when we eat it, 

CAP COM Roger. 

SC It's coming out with no bubbles now. It 

looked like it almost formed a meniscus on top of itself. The 
top of where the bubbles were. 

CAPCOM Roger, Ron. Are they continuing to spread 

out ? 

SC Gas continues to spread out now, and with- 

out pumping anything into it at all — I did that the last turn 
fairly fast -- it's spreading of its' own accord now, and it 
should go on over and cover up the bottom, I think. Once it 
completely covers up the bottom, I think we should go ahead and 
start the (garble) this battery. Okay. Now -- everything's all 
hooked together now. We filled up the bottom of the floor. Hey, 
for some reason, the bubbles seem to be starting to break now. 

CAPCOM Roger. We copy that Ron. 

SC Okay. I don't know if it's coincidence or 

what, but all the bubbles are formed together, especially in the 
center along the plus X axis direction and are about one inch 
wide and then they start about th re e- ei gh ths of an inch in from 
the circumference. 

CAPCOM Roger.

starting to form 

APOLLO 17 MISSION COMMENTARY 12/8/72 GET 43:27 CST 19:01 MC198/2 

CAPCOM How large are the cells Ron? 

SC Well, they vary considerably in size. I can 

see one that's about half an inch across, and then the other ones, 
they've got a great big bubble in it and yet the cell itself is may- 
be down to an eighth of an inch. The bigger ones seem to be on 
the outside and, of course, there are very few bubbles on the out- 
side also. 

CAP COM Okay. 

SC And the bigger ones, generally right now, are 

averaging about, oh a fourth, to three eighths of an inch across 
the cross section (garble). 

PAO This is Apollo Control. 

SC The cells tend to be somewhat polygonal. Let's 

see, we've been going 6 minutes, 4 minutes into the eating part of 
it and the cells are polygonal but they don't seem to be quite as 
straight lined as they were on the ground. 

CAPCOM Roger. Copy. 

PAO Stu Roosa, Apollo 17 back-up Command Module 

pilot is talking to the crew now from the CAPCOM console. Stew 
performed a demonstration similar to this on his Apollo 14 flight. 
That demonstration was not as sophisticated as the 17 test and the 
17 demonstration is expected to provide more exact data on the 
fluid behaviour. 

SC It almost looks like it's reached a steady 

state now. It's 9 minus 2, 7 minutes. 

CAPCOM Roger. 

SC Okay, I think the one thing I neglected to 

menti on 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 19:10 GET 43:36 MC199/1 

SC Gee, I think the one thing I neglected to 

mention is that we essentially have a convex surface from the 
material, in other words, convex with the high part in the 
middle, and, of course, that's where the bubbles are, too, but 
I think you'd generally have that type of a surface anyhow.

SC Roger. 

SC And, are you ready for the trotting gourmets' 

report ? 

CAP COM Roger. Everybody's here with all ears. 

SC Okay. The CDR today had scrambled eggs, and 

three bacon squares, and a can of peaches, and pineapple drink for 
breakfast. And, then later on in the day, he had peanut butter, 
jelly, and bread with a chocolate bar and some dried apricots. 
The LMP had scrambled eggs, four bacon squares, an orange drink 
and cocoa for breakfast. And, potato soup, two peanut butter and 
jelly sandwiches, and a cherry bar and an orange drink. And, that 
hero of the matinee, the matinee idol of Spaceship America, had 
scrambled eggs, bacon squares, peaches, cinnamon toast, orange 
juice and cocoa for breakfast. That's how he keeps his form. And, 
for lunch, he had a peanut butter sandwich and a citrus beverage. 
And, that's it, since there's nobody else up here. 

CAP COM Roger. We copy that. We'd like you to stow 

the high-gain at this time and OMNI BRAVO. 

CAPCOM Jack, we appreciate all your information, and 

we'd like to just pass on some recommendations here from the ground 
that we'd like you to keep on with your regular menu as much as 
possible, and if you do cut anything off, we'd like you to concen- 
trate on eating the meats, the juices, and the fruitcake, which 
are the most effective for maintaining your electrolyte balance. 

SC Okay, Bob. We understand what you're saying. 

We're shooting at eating it all. It's just a lot of food, that's 

CAP COM Rog. We understand, Gene. Also, on that 

group of foods, peanut butter's great for the electrolyte balance, 
also, so you're doing okay. 

SC I knew it was good for something. It couldn't 

be that good without being good for something. I think we're all 
trying to make a concentrated effort also to keep quite a bit of 
water down.

PAO This is Apollo control at 44 hours 

35 minutes. Spacecraft distance 147 866. 

CAPCOM Rog, we're reading you loud and clear. 

SC Okay, I think that big storm that Jack 

was referring to has moved off well to the east of Australia. 
Very definite counterclockwise rotation and then it stretches 
to the south or what might even be the southeast. And then 
just rolls right - we have a big frontal pattern and then rolls 
right into another clockwise rotating low down there near 
antartica. It gives me the impression of a parrots cone 
when he's got his features ruffled. And it in turn has 
another low trailing it arching and then flowing into another 
low that is very near the continent down there of antartica. 
They form a chain as I just described coming from - well 
possibly southeast of antartica. It's hard to really tell 
what east is down there on up to do west of Australia by 
several hundred miles. 

CAP COM Roger. 

SC South of Australia you get ahead of a 

very large cloud mass from there all the way down to Antartica 
that had the tendency to -

shortly. Spacecraft distance 147 953 nautical miles velocity

CAPCOM 17, Houston. 

CAP COM 17, Houston. 

SC Go ahead. 

CAPCOM Just wanted to get COMM there again we 

had some switch over there. You might be interested, we've 
got an ATS map in here from this morning. We can see the 
flow patterns in the antartica just about 120 degrees west 
which is a little closer to South America than what your 
calling I guess. We do see that activity down there. 

SC Okay, Bob and there is a very large 

cloudier mass between Australia and Antartica. It has a 
tendency to want to start a rotation and you can say ahead 
of that it's not too strong right now. We're seeing about 
three quarters of the Earth I guess. Judging from our 
clocks and what we can see it looks like the Sun is setting 
right over the west coast, and it leaves us with about three 
quarters of the Earth available to us. 

CAPCOM Rog, it'll be about 6:15 Los Angelas 

time right now so it's probably sunset out there. 

APOLLO 17 MISSION COMMENTARY 12/8/72 CST 20:08 GET 4 4:34 204/2 

CAP COM Ron, just a reminder from the flight 

plan change last night you will have a P52 coining up here at 

45 hours in your flight plan. 

SC Roger, mighty fine thank you. 

CAPCOM Roger, Ron. 

PAO This is Apollo control at 44 hours 

43 minutes. That was a reminder that we are approaching the 
time where we are going to make the first step in a two step 
adjustment caused by the late launch. This will be to bring 
the Greenwich mean time, the ground elapsed time and the 
flight plan together. What this first step will account for 
an hour of 2 hours and 40 minutes adjustment that will be 
made eventually. The clocks will not be recycled at this 
time at 45 hours. The clock recycling will be accomplished 
later in the mission at 65 hours elapsed time. This 1 hour 
adjustment consists of moving the activities that were 
scheduled in the flight plan to take place between 46 hours 
and 30 minutes and 47 hours up to 45 hours in the flight 
plan. Therefore, during the hour from 45 hours to 46 hours 
we will have accomplished all the flight plan activities 
that were originally scheduled to be accomplished from 

46 to 47 hours. This will put us 1 hour ahead on the flight 
plan and we would pick up the activities originally scheduled 
at 47 hours at 46 hours under this plan. And this would 
proceed in an orderly fashion one hour ahead up to the 

65 hour mark at which time we will synchronize the ground 
elapsed time clock to 67 hours and 40 minutes and at that

that you'd want. It took a jump from 1.3 to 2.4 on that. 

SC Okay. That was with two of us going, and 

part of the time, three of us going. 

CAPCOM Roger.

CAP COM Well, it's not unexpected. Just thought 
you'd be interested.

time does penumbra start? 

CAPCOM Say again the question, Jack. What time does 

wh at s t art ? 

SC With the change in hour, what time does the 

penumbra, what time do we enter the lunar penumbra. 

CAP COM Right now, we don't, Tommy doesn't think we're 

going to go into the penumbra and we're verifying that. 

CAPCOM Hey, Ron, could we ask a question about the 

heat flow experiment setup? 

SC Go ahead. Sure go ahead. 

CAPCOM You mentioned that the lineal chips were all 

on the in the X X plane, and we're just wondering do you mean along 
the X X axis of the spacecraft? 

SC Yes. Along the X X axis of the spacecraft. 

CAP COM Is the long X X axis of the lineal cell along 

the X X axis, Ron? 

SC Yes, that's affirmative. It's right side up, 

if you're looking at the connect panel, you know? 

CAPCOM Yes. That's, they'd like so that the axis of 

that lineal cell would be parallel to the bottom of the panel 100, 
as an example. It's, right now, it's perpendicular to the bottom 
of panel 100, isn't it? 

SC Now wait a minute. Yes, the lineal thing is 

right now perpendicular to the bottom of panel 100. 

PA0 This is Apollo Control at 45 hours 5 minutes. 

Ron Evans is making preparations to again perform the heatflow and 
and convection demonstration. 

SC Houston, America. 

CAPCOM Go ahead, Ron.

I read the thing with lineal cell in a plus X direction, but what 
they mean is lineal cell up. 

CAPCOM Lineal word, I guess is the 


SC Okay, I'll turn around the other for this PTC 

part of it then. 

CAPCOM Wait a minute on that, Ron. We're having a 

debate whether we want to maybe continue the next part the same 
attitude or just rotate it. 

SC Okay. Seems to me you'd like to maybe leave 

it in the same attitude. 

CAPCOM Ron, the only rational reason to change it 

right now is we're hearing word that if you had rotated to the 
other way, that you'd get better pictures on the DAC due to the 
lighting reflection on it. The PI would like to change it back

SC Okay. No problem. Good idea. 

CAPCOM And, that should be magazine SS, 

one you used for the ALFMED tomorrow. 
SC Affirmative, okay? 

SC Okay. Looped the flow about four turns. A 

little bit is running out — one big bubble in it. And, I still 
have a little bit left over even though I wiped it out pretty 
good awhile ago. The meniscus is up to the bottom ring, and I 

APOLLO 17 MISSION COMMENTARY 12/8/72 CST 21:04 GET 45:30 MC208/2 

think we put in eight things in there where it's going to try to 
get the meniscus up to the top bazzle. Is that correct? 
CAPCOM That's correct, Ron. 

SC There must have been a few more bubbles down 

in there again. That was two turns now, and I've got it about 
half full all the way across. 

CAPCOM Roger. 

SC But, maybe there's just about 8 or 10 bubbles 

in i t . 

SC That's three turns. The fluid is exactly 

(garble). And, we're still going on the first fourth of the turn 
now, and we're still (garble) meniscus around the lower baffle -- 
the smaller baffle. 


APOLLO 17 MISSION COMMENTARY 12/8/72 GET 45:53 CST 21:26 MC209/1 

SC Okay, it looks like about 6 of the bubbles have 

developed into three for some reason. 
CAPCOM Roger. 

SC It was doing real well, then on 7th turn a bunch 

of bubbles came in again. 

CAPCOM Roger. Ron, I might have given you a bad call 

before. We don't want the DAC on until just before that 2 minute 
mark here where just prior to going experiment heat select flow 
pattern low. At that point is where we want the DAC on. 

SC Okay, you want the DAC on when it starts heating 

up . 

CAPCOM That's affirmed. 

SC Okay. You, know I may have lost track of 

the turns here, but I think we've got 7 and a half or 6 and a half 
turns in here. And it still hasn't overflown that first lower baffle. 
I've got a tremendous concave convex surface on the fluid, but it 
still hasn't broken the maniscus of the first baffle. 

CAPCOM Roger. We copy that. 

SC Okay, I'm going to go ahead and take it another 

turn, because it was my understanding, we wanted to try to get in 
the second baffle anyhow. So, I'm going to take another turn of 
crytox and put some more in there. 

CAPCOM That's correct, Ron. Ron, if that doesn't do 

it, they're saying you might want to take a pencil or something and 
stir it a bit to try and break it up into lower baffle into the 
upper b af f le . 

SC Okay, I'm afraid, may have it all over the place 

if I do that, but I'll try it. 

CAPCOM Roger. Very slowly. 

SC Right. 

CAPCOM Ron, just a question here, while you're watching 

it here, do you have any bubbles in the lineal cell? 

SC Yes. This one is going to be interesting. 

There are about a dozen, 9 to a dozen small bubbles right next to 
the inject board, and about the same number right in the center of 
the convex portion of it. 

CAPCOM Roger, Ron. We didn't copy your answer to the 

question about any bubbles in the lineal. 

SC No, I didn't get to your question on that. In 

the lineal unit, there are no bubbles whatsoever. 

CAP COM Roger. Thank you. 

SC There might have been very slight movement, as 

a matter of fact, I see just a very slight movement even now. The 
particles in there, they're still lined up in the Y Y direction, 
essentially. Although, it looks like some of them may have deviat- 
ed from the front of the lineal unit back toward the center, toward 
the back of the lineal unit, as you call it. I missed your 2 minute 

APOLLO 17 MISSION COMMENTARY 12/8772 GET 45:53 CST 21:26 MC209/2 

SC start time there, but I can keep track of it 

here, so we'll start the DAC and I'll turn this to low at 245. 

CAPCOM Okay, we've got a hac on it, Ron, if you 

started it, we started we started our clock. 

SC Okay. You know, just for future reference, 

we like to do things in OG and without jarring or jiggling, we 
want to make sure that the switch actuates with a minimum of 

CAP COM Roger, a good point. 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 21:39 GET 46:04 210/1 

SC Okay, that's just now starting to develop 

looks like circular cells great big ones. And then some of 
the bigger ones are subdividing now. 

CAP COM Okay, we got that. 

SC Some of them are even getting bigger 

one of them is about three quarters of an inch in diameter. 
And it hasn't divided yet at all. 

CAPCOM Those are real good comments, Ron, I was 

just talking with the experimenters and if you've got nothing 
else to do giving us some sizes of those cells would certainly 
be very beneficial. 

SC Okay. Okay, frame 2 7 was taken at an 

elapsed time of about four minutes. 

CAPCOM Okay, we've got that. 

SC Stu, this is Jack I was taking the pic- 

tures. I took four pictures about 20 seconds a part - the 
sequence just after he started it. And that ended with - or 
started with frame 26. 

CAPCOM Okay frame 26 for 4 seconds - I mean 4 frames. 

SC Okay, that one cell I spoke of that was 

about three quarters of an inch in diameter is now about an 
inch long and maybe three quarters of an inch wide. Each - 
all of the cells seem to be bigger in general. Their bigger 
this time two small ones at about an eighth of an inch and 
along along one side. The other one is a half inch oh a 
quarter of an inch, an half inch and then a circular when 
you get around to the annulus of the cup. Then you start 
getting circular slides instead of straight sides. All of 
the flow comes from the little center spot and flows outward 
from the center toward the outside of the cells. 

CAP COM Okay. 

SC This happens to all of the bubbles that 

disappeared except two. 

CAPCOM Ron, is the smaller cell you see about 

an eighth of an inch across. 

SC The smallest cell I see is a four sided 

one that looks like a diamond. And it's an eighth of an 
inch on one side and an eighth of an inch on the other side 
and maybe three sixteenths on the other two sides. 

CAPCOM Okay that sounds - that's a good descrip- 

tion, Ron. I know on mine some of the smaller ones didn't 
show up in the film and we were not sure what size they are 
so you might before you quit bracket the smallest or the 
biggest cells by your estimate of the size. 

PAO This is Apollo control at 46 hours

SC And the information for (garble) experiment 

- the orientation was 90 degrees from us (laughter). Lineal 
cell was on the right and the lineal cenl was in line with 
the X axis. 

CAPCOM Okay, Ron, we got, we had a drop in on 

signals right there and we did get your last comment about 
the orientation. We missed some comment about the frame 
numbers, I think came from Jack. 

SC Okay, somethings a little different on 

this one here. Right at the top of the low circle it looks 
just like a finger, it's a curved surface that goes out. It 
almost touches the, the circumference of the dish and it 
looks just like if you're holding your finger up and looking 
at it. It's that type of a shape to it. It comes back 
down and it's about a half inch wide, the flow again 
iminates from a source that is almost on the finger tip 
you mi gh t s ay . 

CAP COM Okay, we copy. 


APOLLO 17 MISSION COMMENTARY 12/8/72 21:46 CST 46:13 GET MC211/1 

SC And Houston, did your listing or DSC if 

your listing? Had a little bit of felt loop, there's 
the end of film now. May as well stop it. Anyhow, I went to 
high for a little ways. 

CAP COM Okay, Ron. As you came back in, 

I didn't get all of that. Understand you ran out of film 
and say, the unit. 

SC Well, I still had a little bit of film when 

the cool down period was less so I went back to high on the 
flow pattern just to see what would happen. And it looked like 
they were starting with again larger size cells developing 
into smaller ones. And initially, all of the cells were 
about a half inch in diameter. And they were closer to the 
periphery of the dish then they were in the low position. 

CAPCOM Okay, we copy that, Ron. 

CAPCOM After you went to high, after the 19 min- 

utes, how long was it before you started seeing a change? 

SC Ah, it was within a minute. See it cooled 

down pretty rapidly at the end of the 2 minutes, all of the 
cells had essentially dissolved. You had some radial lines 
on the outer perimeter of it, the cells were on the outer 
side, degraded into a strictly radial lines. Back to the 
second row of cells. The row of cells that were on the inside 
kinda joined together and all ended up into one or two large 
cells about an inch - about 3 - 3/4 's of an inch across. 

CAPCOM Okay. Sounds like real good data (garble) 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 2200 GET 42:26 MC 212/1 

SC I still have it in high and the pattern that's 

developed is almost identical to the - what was happening in low, 
except it seems to be happening in a faster rate. 

CAPCOM Okay, we copy that. 

SC Triangle or a little diamond developed down there 

and it disappeared. Only this time it kind of joined with a 
different little cell, but it was the same cell next to it. I still 

It's about an inch long at 11 o'clock as I had before, 
finger it's developing about 12 o'clock and another 
And they seem to be migrating again toward the

everybody's real happy with the data and experiment and looks like 
you did a super job and you might as well tear it down and pressahead 

SC Okay. I still got it in high. And I'm kind of 

sucking the fluid back down the intake, and as I get the fluid 
thinned out, low and behold, there's a whole bunch 
underneath there. And each bubble is a source for

of the way. Okay? 
CAP COM Sure. While 

that, you might part the optics, 
SC Okay. 

CAPCOM And on that same line, Ron, we did notice 

several times while people were watching through the optics that 
they went to zero, and it's no problem if the rates are low, 
but just a reminder that we don't want bump them into the stops 
with any kind of a rate.

that people - you were all looking around, I guess and you might - 
it's easy to miss that trunion going to zero I guess. 

SC Houston, 17. 

CAPCOM Go ahead, Jack, Gene. 

SC I'm ready to update your weather in the western 

Pacific if you're interested. 

CAPCOM Roger. Go ahead. 

SC Still can't quite figure out what that circulation 

around New Zealand means. It looks like it's merging with some more 
weather in the southeast. I suspect it's stormy there but I still 
it's not a terribly well developed storm although it seems to be 
broadening in its extent. Australia is completely free of any 
significant weather and almost completely clear and free of 
clouds. The - there appears to be a front - although right now 
it does not look too intense, approaching from the southwest, and 
it looks like it's about 5 degrees of longitude south of the 
southwestern tip of Australia. The typhoon gerous Mr. Reese I 
guess it is, appears to be just about the same position it was 
yesterday. And that is north of Borneo, and between Viet Nam and 
the Philippines. 

CAPCOM Roger. We see that on the prog here, Jack. 

SC Okay.

CAPCOM Jack, we've been out of COMM here if we've 

missed any of your last report hereRon, did you ever get 
your P23 data from today? 

SC That's negative, never did- 

CAPCOM Okay, just got some updating information for 

you if you want to listen to it. I don't think you need to copy 
it down. 

SC Very good, sir, go ahead. 

CAPCOM Okay, Ron, the effective horizon was 

25 plus or minus 6 nautical miles which is real fine. The sub- 
stellar pointing error was 1 arc minute plus minus arc minute 
which is less than the 1 Sigma error. The marking data was 
extremely consistent and all techniques and procedures were 
excellent. And the horizon updates from the current onboard 
value was 28 - is not required, so you're extremely good P23's 
Out s t an ding . 

SC Okay, that's good to hear. Great. Thank 


CAPCOM And I do have one imput from your other 

half. There's a concern that you spill grape juice on your 
flight suit it's hard to get out, so be sure and when you're 
eating - drinking grape juice you want to make sure you learn 
to drink it right. 

SC Okay, we'll try that for sure. 

PAO This is Apollo Control at 46 hours 46 minutes 

The display which shows distance and velocity is referenced to 
the Moon at this time so these numbers I'm about to give you 
will be Moon referenced and not Earth referenced. Apollo 17 is 
80 322 nautical miles from the Moon. Velocity 3 349 feet per 
second. The crew is in a meal period at this time and we don't 
expect much conversation for some time. Earlier today, while 
the Lunar Module was being checked out and during a test of 
simultaneous dual communications capability from Challenger and 
America, a portion of the conversation was lost due to a com- 
munication line configuration in the Public Affairs distribution 
system. We have now obtained tape of this lost conversation from 
the Air/Ground recorders in the Control Center and will play 
that for you now.

the tunnel index angle - that's a positive plus 1.2, is that 

SC Standby, I don't believe it yet. I want 

to check it myself. Yeah, Gordo, that's what I e ad but I 
figure it's his privilege. 

SC I was checking for any scratches on the drogue 

but it doesn't look like there is any on there.

SC Okay, Houston. The roll dockings index is 

on a 1.2 - a plus - 1. - a plus. 1.2. 
CAPCOM Roger. Plus 1.2. 

SC And - let's take a look up there in the 

docking latch number 4. The bungee is parallel - Roger - 
bungee is parallel but its not fully extended. You look down 
in the end of it and - you know - and its not fully extended. 
And - and the - capture - the docking latch itself or the 
docking lever is loose on the docking ring. So, its looks 
like to me that's when I ought to recock and fire it again. 

CAPCOM Okay, we copy that, Ron. Stand by. 

CAPCOM Ron, can you estimate in inches how far 

down the bungee pistonis? 

SC Yeah, its down about a half an inch. 

CAP COM Roger. 

SC And - a - when I take the - and move the 

handle back a ways and I can take the - hook - there I did 
it ... I took the hook and I pulled it back off the docking 
ring and then it caught again, so now it won't go back over 
the docking ring. Maybe - I just lifted the hook off the 
docking ring with my finger. 

CAPCOM Roger. 

SC (garbled). 

CAPCOM Say, Ron, I would like to caution you 

again, sticking your finger around or under that hook - there 
may still be some spring energy stored up there that could 
release . 

SC Oh, you betcha. Yeah, I know that. 

No, I was just touching the top of the hook when I pulled it 
back off the docking ring. 

SC I'll pulling back onto the docking ring 

and it looks like its back in the cocked position now. 

CAPCOM Okay, I think we've got the picture. 

SC Do you want me to open the hatch here, 

Jack, or do you want to - while they're thinking about that 
I'll get out of the way and come on and open the hatch. 

SC (laughter) Can't get up and can't get 

down. - Okay. - 

CAPCOM We're having a long conversation about that 

latch Ron, why don't you all just press on down the checklist and 
leave it as it is, while we think about it? 

APOLLO 17 MISSION COMMENTARY 12/8/72 22:27 CST 46:50 GET MC-214/2 

SC Okay, that's what we're doing here, Gordo. 

SC Okay, Gordo, do you want the 02 heaters 

1 and 2 off and 3 auto? That's what you've got. 
CAPCOM Yeah, that's fine. 

SC Okay, he's going to open the hatch and 

IVT. Gordo, let me tell you a little more on that docking 
latch. When I looked at it, of course my handle was flush 
against the edge and it was also - essentially - locked in position. 
But since the bungee was down on the thing I took hold of it 
and I felt that the hook itself was loose. Okay, so I took 
the handle and the handle will come back- would come back once 
you pressed the little button you know to release the 
handle. The handle would come back to about a 45 degree 
position just like it normally does when you try to cock the 
latches. Okay, with the handle back in that 45 degree position, 
then I grabbed hold of the hook and brought the hook off of 
the docking ring with my finger and back to about that 
45 degree position again just like it was comparable to the 
first cocked position. And that's the way it is right now. 
CAP COM Okay, Ron. 


APOLLO 17 MISSION COMMENTARY 12/8/72 GET 46:59 CST 22:32 MC 215/1 

SC Okay, one piece of tape coming up shortly, 

provided I can find the tape. Ah, here it is. Okay, Gordo, 
I'm running up through the tunnel from America to Challenger. 

CAPCOM Roger. 

SC Piece oft ape coming up. I'll tell you, 

Gordo, it's remarkably clean up here. It doesn't look likee 
snow storm that I remember coming into last time. 

CAPCOM Rog, understand. 


SC (garble) up here. Hey, you did a good job, 

friend. Hey, that's good, where is it? Oh, you you can see it! 
Is it straight out there? Let me see, I want to see. I want to 
take a look at it, too. Hey, there it is, sticking straight out. 
Okay, Houston, America has a VHF antenna - looks deployed per- 

CAPCOM Roger. 

SC Hey, you guys are upside down in there. 

(Laughter). The commander's window has a slight amount of 
condensation on the lower left edge - that's the lefthand edge, 
really. It seems to be just there as the sun warms the window. 

CAP COM Roger, Jack. 

SC Okay, Houston, 74 on 1-3. 


SC Geez, what was that? What was that from? 

What the hell is this? 

CAPCOM Sounds like the cabin (garble) is working 

ok ay . 

SC Holy smoly . Did the heart beat go up on 

that. (Laugheter). Sun's out - there's 
sun out in the AOT. 

CAPCOM Roger, Jack. 

SC Okay, I'm looking out the "V" and I see a 

VHF antenna and part of a umbra radar antenna in position one. 
Position two looks right in the radar antenna and, as I said 
yesterday, it was beautiful. 

CAPCOM Roger. 

SC Position three, I see the other side of 

America and very, very clean air, very clean. Okay, I got a 
good view of the side of the service module and you can see these 
little blisters in the side of the covering there quite distinctly 
I think people were talking about those before. 


SC Yeah, I take that back. That's the side of - 

that's the side of the command module we're looking at that has 
the little blisters on it. Got to get oriented up here. Got a 
great view of the hatch - you (garble) - watch your eyes and 
everything. Look up rather than into - the sun is in the 
lower portion - -

This is Apollo Control at 47 hours - - 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 22:52 GET 47:19 MC 217/1 

PAO This is Apollo Control at 47 hours 18 minutes. 

That completes the tape from this afternoon. At this time Apollo 17 
is 79 293 nautical miles from the Moon. With the lunar referenced 
velocity of 3343 feet per second. The flight director has 
just gotten another update on the S-IVB impact prediction, based 
on tracking to date. The newest prediction is that the impact 
will occur at an elapsed time of 86 hours 59 minutes 55 seconds, 
at 3 degrees 58 minutes south latitude, 12 degrees 35 minutes west 
longitude. While that tape was playing, there were several con- 
versations with the crew. Including one between Brigadier General 
Tom Stafford and Gene Cernan. Stafford was Cernan's spacecraft 
commander in both Gemini and Apollo. We'll play those conversations 
for you now and then come back up live. 

SC Houston, 17. 

CAPCOM Go ahead. 17 Houston, go ahead. 

SC I need to make a correction. Roger, I need 

to make a correction. It looks as if that storm area that was in 
New Zealand yesterday has moved up across the two islands and is 
now sitting northwest. It's getting a little hard to identify the 
smaller islands in the Pacific but pretty sure I've got it in 
the right place now looking at the map. And it is northwest of 
New Zealand and it looks like New Zealand is probably having reason- 
ably good weather today, although I suspect it rained last night. 

CAPCOM Roger, Jack. That's interesting because on my 

prog it doesn't show a thing down that area. It just may not be 
up to date here yet. 

SC Well, there may be nothing down there except 

some cloud patterns and - but that's all I can see of course. The 
front that's south of Australia now, I presume front, just looking 
at a fairly well developed - although narrow cloud line, is about 
by about 10 degrees south of Perth right now, southwest of Perth, 
and runs on a northwest-southeast line over to a point about 
10 or 15 degrees southwest of Tasmania. And then it intersects 
a curved front that runs from there up to Tasmania, and then back 
around down south of New Zealand about 10 degrees. 

CAPCOM Roger, Jack. 

SC Say, Bob, this is Gene. I got some new sensors 

on you might want to take a look at them. 

CAPCOM Roger, good show Gene. We were just wondering 

about that and I'll let you guys on my left here make sure looking at 
them. We're not getting any data yet, Gene. 

SC (Garble) we're starting to get - from - just 

off Luzon on a northeast trend (garble) seen so far a shadow line 
of very thick high clouds overlying some thick lower clouds behind 
the front. 

CAPCOM Roger. You might have - be of interest %j\ board 

there the FIDO. Jack we've been COMM drop out there on this OMNI 
if you swing around on It. 

APOLLO 17 MISSION COMMENTARY 12/8/72 CST 22:52 GET 47:19 MC 217/2 

SC Okay, where did I leave you, Bob? 

CAPCOM Well, I'm not sure because we picked up a 

number of different bits and then we dropped it all. 

SC Did you get the overcast over Korea-Manchuria 

bit ? 

CAP COM Negative, I didn't get that. 

SC Okay. That generally - south China looks 

clear. I haven't had a real good look at it yet it's out on the 
LM, It's clearly however, overcast over Korea and Manchuria. It 
does not appear to be frontal weather there though. The dominant 
front in the northwestern Pacific stretches on a northwest line 
from just off Luzon on up as far as I can see to de te rmin ate r . And 
it seems to be an extremely strong front with what I would guess 
is heavy air-mass weather all along it and up to the east- northeast 
of Japan there's an excellent example of a shadow line from some 
very thick high clouds on solid overcast of lower clouds. Don't 
see any major cyclone development along it or wave development. 
It just looks like a very strong air-mass front. 

CAP COM Roger, Jack, we've got it on our prog here. 

We don't see the one on the northeast part of Japan but, we 
do show a front prog for tomorrow morning going off from Taiwan 
and to the right of Taiwan eastward, pass the Ryukyu Island and 
just on into the northern Pacific there. Looks like pretty heavy 
cloud mass there. 

SC Roger, that's the one I'm - Roger, that's the 

one I'm looking at and it's extremely heavy and right now it's - in 
fact it starts about in Luzon and looks like Taiwan is almost 
on the back side of it. 

CAPCOM Yeah. That's what our prog - it shows it 

right on Luzon and Taiwan's clear. 

SC Very good. 

CAP COM We'll keep up with you yet there, Jack. 

Say, you may be interested. We've got 9 hours of good tracking on 
the - after the midcourse and we show a perilune of about 52 miles 
which confirms a good midcourse. 

SC Sounds outstanding. That's great, you can 

cross off the canister by the way, it's changed. 

CAPCOM Okay, EECOM' s happy about that now finally. 

And (garble) your data looks good. 

SC Okay. I never had a chance to tell you, Bob, 

but you - as you see - I presume I - the LMV no longer had sensors 
on . 

CAPCOM Roger. We confirm that. 

SC By the way, those were the - as you know the 

censors that we put on at the Cape, and they still seem to be 
in good shape when I took them off. I figured I'd let things 
rest a while and then I'll put them on again tomorrow. 

APOLLO 17 MISSION COMMENTARY 12/8/72 CST 22:52 GET 47:19 MC 217/3

SC Go ahead, TP. 

CAPCOM Yeah, I was going to say is that talkative 
commander on board. 

SC How are you doing down there?

Gene, on - I think you're the jinx on Gemini 9 for all the 
delays. Over. 

APOLLO 17 MISSION COMMENTARY 12/8/72 GET 47:27 CST 23:02 MC 218/1 

SC No way, you got a longer history than I do. 

CAPCOM Everything's looking great. 

SC Yeah, It's looking good on board. We're - 

I think we're pretty well squared away. We've got our stowage 
in shape and we're in the hous ecleaning routine and that's about 
fifty percent of the battle.

SC Houston, 17. 

CAPCOM Go ahead, Jack. 

SC Say, I'm just a little curious about 

the difficulty on holding the OMNIs, is that about the same 
as past missions or are we loosing a little bit more than 
us ual. 

CAPCOM We're going to have Ed here give us a 

discription for a minute so let me stand by. 
S C Ok ay . 

CAPCOM Jack, according to that - to starward 

INCO over there, due to this new 210 down at Tin Bin Billa, 
we are holding actually longer than the past history. 

SC Okay, I just guess I've never been on 

this end before. 

CAPCOM Roger. Do you hear it on board when 

we break like that. 

sc Yes, matter of fact with our squelch enabled 

we loose all the background noise and we know when we're 
picking you up because we start to get background noise 
again . 

CAPCOM Roger, in other words you are able to 

stop talking or something when when you know we're breaking 
like that? 

SC Well, if we haven't been talking we'd 

break lock, no unless we're watching the meter we want, 
we loose you when you get about 55 say 60 percent signal 
strength and apparently we're not talking to yoTj when we have 
less than that. 

CAP COM Roger. Yeah, INCO gave me a briefing 

tonight and showed me what chart to watch so I can look at 
numbers when to talk, I've been talking myself to much 
lately . 

sc Yeah, they have a beautiful chart there 

for that purpose. 

CAPCOM I never really wanted to be an INCO BUT 

I guess I was forced to tonight. 

SC Comment for that one, Bob, but I better

PA0 This is Apollo Control at 48 hours 9 minutes. 

Apollo 17 now 77 623 nautical miles away from the Moon and the 
lunar referenced velocity 3 333 feet per second. Here in the 
Control Room, flight director Gene Kranz and his white team are 
preparing to relieve the orange team which has been directed 
tonight by flight director Chuck Lewis. Major activities during 
this shift have been the heat flow and convection demonstration 
which has been performed twice during this shift. Once, while 
the spacecraft was nulled in all three axes and again after the 
passive thermal control spinup mode had been established. That 
demonstration is to provide data on behavior of fluids in a low 
gravity field and the information learned from the demonstration 
could be valuable in the future science experiments and perhaps 
for manufacturing processes in space. The crew is in its pre- 
sleep checklist at the present time and we have a - again a new 
update on the S-IVB impact just provided by the flight dynamics 
officer updates impact time to 86 hours 59 minutes 38 seconds at 
3 degrees 37 minutes south latitude, 12 degrees 7 minutes west 
longitude. We do not anticipate a change of shift briefing at 
the end of this shift. Handover is scheduled for midnight and 
there will be no change of shift briefing. At 48 hours 12 min- 
utes this is Mission Control Houston. 


APOLLO 17 MISSION COMMENTARY 12/8/72 CST 23:46 GET 48:13 MC 222/1 

SC Houston, 17. 

CAPCOM Go ahead. 

SC Roger, one final word, I got those 

pictures and I tell you that typhoon off - north of Barneo, 
looks like it's right off the coast of - the east coast of 
Viet Nam now and it's about as tightly organized and solid 
as anything I can remember seeing in photographs. It looks 
as if, from yesterday, it's moved quiet a bit to the west. 

CAPCOM Roger, we concur the prog for 12:00, 

let's see that's about 6 hours from now. Shows it to be 
right over the Viet Nam area, the Viet Nam Peninsula there, 
so looks like it's moving the way they are proging it, huh. 

SC Yeah, it certainly is. It's moved from 

just a little bit west of Luzon over to the coast there so 
it's a pretty healthy storm. 

CAPCOM Roger. It looks on the prog chart here 

it looks real tight, it's a very - very centralized thing in 
a real tight circular. 

SC Oh yeah, you better believe it, it is 

really, it is tight, it's really no bigger than the, in terms of 
cloud pattern, no bigger than the - say South Viet Nam itself. 

CAPCOM Roger. How're you getting that, Jack, 

are you looking with the monocular now? 

SC That's affirm. Monocular still gives real 

good resolution on the cloud patterns. Naked eye you just 
see the masses, but with the 10 power monocular it's perfectly 
adequate for seeing the kind of patterns we're talking about. 

CAPCOM Roger. I understand. Well, guys, I guess 

I wont get the chance to say goodnight to you because Parker's 
going to come in to put you to bed. 

SC He avens . 

CAPCOM And we'd like you to clear DESKY if you 


SC Say goodnight, Bob. 

CAPCOM Say goodnight, Dick, huh. One last 

word, you know we're always hounding you guys, really don't 
mean to, but we'd like to see you clear DESKY so something 
doesn't burn out, don't know the exact words on that, but - 


Okay, we'll give you a clear DESKY. 




Goodnight, Robert. 

We'll see you tomorrow, troups and we 


had a good show 

today and we'll have more tomorrow. 


Ron says goodnight, Bob. 


Roge r . 


Robert Parker, are you there. 


That's affirmative. 


Bob, you're just in time to put us to 

sleep and I'll give you one last little ole observation 
here. Extremely bright zero base point right off the 
northwestern corner of Australia right at Carnarvon, it's 
bright as I've seen. They must have a pretty good surf or 
something going there. 

APOLLO 17 MISSION COMMENTARY L@?*?&<a CST 23:46 GET 48:13 MC 222 /2 

CAPCOM Okay, that sounds good. 

CAPCOM Okay, 17, we copy all that and I gather 

you're going to sleep at this point. 

SC Well, we're going to try, Bob, I don't 

think any of us are real sleepy right now, but, we're going 
to give 'er the old space try, here, and I'm sure we'll be 
a sleep before long. Ron is on watch and if you don't 
wake him up with your voice give him a crew alert, he says 
he'll wake up with the master alarm. 

CAP COM That's a healthy sign. All right, guys, 

if I stick around long enough in the morning I'll wake you 
up . 

SC Okay, Robert, are you happy with you're 

antenna configuration? 

CAPCOM That's affirm INCO is happy. 

SC Okay, you have anything else for us, 

I'll take care of our sleep configuration if you don't. 

CAPCOM Okay, stand by, I'll go around the MOCR 

here with white. 

SC (Laughter) 

CAPCOM Okay, lot of happy people down here with 

nothing to ask you. 

SC Okay, nice to have everybody happy, 

and that includes the Biomed on the Commander, huh. 

CAPCOM Okay, I guess they are happy. 

SC Okay, are you going to sing to Ron in 

the morning to wake us up? 

CAPCOM Depends on how soon you guys decide to 

wake up in the morning. I'll be around for 8 hours any way. 

SC What's your expected GET of awake. 

CAPCOM Stand by. Okay, 17, I should say - 

SC (Garble) 

CAPCOM Go ahead. 

SC Yeah, we're just going to say the 

same thing. 

CAPCOM Okay, show 56 on your clock. In fact, 

Dr. Kranz here, just decided that you guys get another 
half hour in the morning if you wanted it. You better tell 
us now 'cause we'll wake you up at 56 and ask you if you want the 
other half hour then, unless you tell us. 

SC Yeah, why don't you give us another 

half hour and if we happen to wake up and want to move 
around, well, we'll do it. 

CAP COM Okay, we'll wake you up at 5 6:30 . 



SC Yeah, why don't you give us another half 

hour and if we happen to wake up and want to move around a little, 
we'll do it . 

CAPCOM Okay, we'll wake you up at 6 or 6:30. 

PAO This is Apollo Control at 48 hours 39 minutes. 

We now have turned off the voice subcarrier up to the space- 
craft and INCO just a few minutes ago reported that the crew has 
also turned off the voice subcarrier from the spacecraft, indi- 
cating that they have completed their presleep preparations and 
should begin scheduled 8 hour rest period shortly. Spacecraft 
Communicator, at the present time, is astronaut Robert Parker. 
He has replaced Robert Overmyer in that position and in Mission

Flight Director Gene Kranz is going around the room polling 
each of his Flight Controllers on the mission status and all 
the reports are coming up very good. The orbital science 
officer said that the temperatures in the S 1MB AY where the 
various scientific instruments will be used in Lunar orbit 
to observe the Moon from orbit appear to be about as would 
be expected at this time. During the previous shift the film 
in the panoramic and mapping cameras was cycled and this is 
done once every 24 hours if the cameras are not used, to prevent 
the pressure points on the film in the transport mechanism 
from creating striations in the film emulsion, and those 
cameras are cycled ahead several frames to move that pressure 
point around on the film emulsion. During Lunar molule house- 
keeping when the crew entered the LM on the previous shift, 
everything looked to be in order in that vehicle. And the 
guidance and control officer reports that the midcourse correc- 
tion maneuver performed earlier in the day - was very close 
to nominal. Also, the command module is running a bit ahead 
of the flight plan schedule as far as reaction control system 
propellent usage and service propulsion system propellent 
usage and we have a bit more than predicted for this point 
in the flight. And the Electrical Environmental Communications 
Officer, EECOM, said that in general the command module - 
the command and service module appear to be in very good 
shape. Apollo 17, at this time, is 75 975 nautical miles 
from the Moon and we're showing a velocity with respect to 
the Moon of 3325 feet per second. We don't anticipate any 
further conversation with the crew, having said "goodnight" 
to them - and we are planning to give them an additional 
30 minutes on their rest period if they so desire. The rest 
period, according to the flight plan, is scheduled to end at 
a ground elapsed time of 56 hours. However, we do not plan 
to put in a call to the crew until 56 hours 30 minutes, giving 
them the option to sleep an additional 30 minutes if they 
so desire. We showed at 48 hours 38 minutes, or about 23 min- 
utes ago, that they had turned off the voice sub-carriers 
indicating that they were preparing to bed down and get to 
sleep. During this sleep shift we'll plan to have the air- 
to-ground lines down to minimize the amount of noise on these 
circuits. we'll be recording any conversation with the crew 
and will be prepared to bring the lines up in very short order 
should we have any calls from the crew. At 49 hours 2 minutes, 
this is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 49:57 CST 0130 MC 225/1 

PA0 This is Apollo Control at 49 hours 57 minutes. 

It's been nearly an hour and a half since we said goodnight to 
the crew and there's been no change in the status of the 
spacecraft or operations here in the Control Center. Every- 
thing's progressing along very smoothly at this point. We 
don't expect to put in a call to the crew until 56 hours 30 min- 
utes ground elapsed time or about 6 and a half hours from now. 
Apollo 17 is now 74 098 nautical miles from the Moon and the 
spacecraft velocity is 3 317 feet per second with respect to 
the Moon. The flight dynamics officer has the option of setting 
up the display which gives us the velocity of the spacecraft and 
its distance relative to either the Moon or the Earth. His 
option is to look at the spacecraft position and velocity with re- 
spect to the Moon or to Earth. At the present time, we are 
looking at those parameters with respect to the Moon. The large 
display plot up on the large 10 by 20 foot describing plotter 
display at the front of the Control Center shows us that the space 
craft is now 'approaching 160 000 nautical miles from Earth. At 
49 hours 59 minutes this is Apollo Control Houston. 


APOLLO 17 MISSION COMMENTARY 12/9/72 0320 CST 5058 GET MC-226/1 

PAO This is Apollo Control at 50 hours 58 min- 

utes. The crew has been in a rest period now for about 
2 1/2 hours. The Flight Surgeon has had bio-medical data on 
the Commander, Gene Cernan. It indicates that at least 
Cernan is soundly asleep at this time and we presume that 
all 3 crew members are sleeping. Wake up call is scheduled 
for 56 hours 30 minutes or about 5 and a half hours from now. 
Apollo 17, currently 160 762 nautical miles from Earth and 
we're showing the spacecraft 72 200 miles from the 
Moon and its continued to be very quiet in Mission Control, 
almost no conversation on the loops here and no change in 
any of the systems aboard the spacecraft - everything going 
along very smoothly and performing well at this time. The 
cabin temperature at the point we monitor it, that's where 
our telemetry which is the outlet of the air flowing into the 
cabin, shows the temperature at that point to be about 
63 degrees. The cabin temperature itself would be somewhat 
warmer than that, probably up around room temperature — 
68, 69 , 70 degrees - in that area. At 50 hours 59 minutes, 
this is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/9/72 0330 CST 5158 GET MC-227/1 

PAO This is Apollo Control at 51 hours 

57 minutes. We've had no signs of any activities from the 
Spacecraft and it appears that the crew is sleeping at this 
time. Apollo 17 some 70 200 nautical miles from the Moon. 
And we have a clock counting down to the time at which the crew 
is scheduled to awake - some 4 hours from now. Actually, 
that would be the earliest that we would expect to hear from 
them and prior to beginning the rest period we advised them 
that we would not plan to put in a call until about 30 minutes 
later than called for in the flight plan. They were about 
a half hour late getting the rest period. Tomorrow's 
schedule is relatively uncluttered and Flight Director, 
Gene Kranz, decided to give them the extra 30 minutes of sleep 
if they desire to take it. On awakening the - one of the 
main activities in the flight plan for today has the crew 
re-entering the lunar module, Challenger and partially power- 
ing the vehicle up and running some additional checks. And 
there has been no change in the status of the spacecraft 
based on the telemetry information we're getting here in 
Mission Control - everything continues to perk along very 
smoothly. At 51 hours 59 minutes, this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 4:30 GET 52:57 MC 228/1 

PAO This is Apollo control at 52 hours 57 minutes. 

We're now midway through a scheduled 8 hour crew sleep period. 
And it continues to be very quite here in mission control. No 
signs of activity aboard the spacecraft, and everything going along 
very smoothly. The flight dynamics officer has been working on the 
trajectory, and looking at tracking data as a result of the 
midcourse correction performed yesterday. And at this point it 
appears that no further midcourse maneuvers will be required to 
get Apollo fif - Apollo 17 into lunar orbit at the desired altitude 
and time. However, the flight dynamics officer is going to reserve 
final decision on that point probably until tomorrow. Although it 
does appear certain at this point that there will be no midcourse 
correction required at the midcourse correction three opportunity. 
And probably not even at midcourse correction four. Our data 
displays at this time show Apollo 17 68 237 nautical miles from the 
Moon. And on a different display we're reading 165 5 84 nautical 
miles back to Earth. At 52 hours 59 minutes this is Apollo control 
Hous ton . 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 0530 GET 53:57 MC 229/1 

PAO This is Apollo Control at 53 hours 57 

minutes continuing very quiet at Mission Control. Now 
about two and one half hours remaining in the crew sleep 
period. The flight plan calls for the sleep period to 
end at 56 hours Ground Elapsed Time, however, we don't 
plan to give them a call until 56:30, giving them the 
option to sleep for an additional 30 minutes. Apollo 17 
now 167 000 nautical miles from Earth and we are showing 
velocity with respect to the Moon at 3 293 feet per second, 
some 66 300 nautical miles from the Moon at this time. 
This is Apollo Control at 53 hours 58 minutes. 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 54:51 CST 0630 MC 230/1 

PAO This Is Apollo Control at 54 hours 

57 minutes, some 1 hour 33 minutes now from the scheduled crew 
awakening time. What has been a very uneventful sleep shift 
for the crew and a very quiet period here in Mission Control. 
After the crew awakes, one of the activities on their schedule 
for the day will be to update the clocks for the spacecraft, 
we'll be updating the clocks here in Mission Control at the 
same time. This clock update is occasioned by the fact that we 
lifted off 2 hours 40 minutes late from Cape Kennedy, however, 
in order to place the spacecraft in lunar orbit at the same 
diurnal time or the same Sun time, and retain the lighting con- 
ditions desired for the lunar landing, the translunar injection 
burn was given a slight bit longer burn - just a little bit 
more energy put into that burn - trip time to the Moon decreased 
by 2 hours and 40 minutes. The net effect of this is that 
we now arrive at the Moon at the same time that we would have 
arrived had the liftoff been on time. One other effect is that 
the crew has a net 2 hours and 40 minutes less time to accom- 
plish those things that needed to be accomplished in the trans- 
lunar coast. This is of small consequence because the 
translunar coast time is relatively a slack period for them, 
however, in order to avoid any sudden shift in sleep periods 
and that sort of thing, the time has been made up in two 
increments - the first one of 1 hour at 45 hours in the flight 
plan. The crew activities were jumped ahead by 1 hour and they 
essentially began doing those things that were called for 1 hour 
later in the flight plan. They will again jump ahead an hour 
and 40 minutes and that'll occur at 65 hours. By that time they 
will have completed all those activities required up through 
67 hours 40 minutes in the flight plan. Or, in other words, 
they'll have completed all of the activities required to get them 
into lunar orbit 2 hours and 40 minutes early and in order to 
make the clocks then agree with where the crew will be in the 
flight plan, we'll jump the clocks ahead 2 hours and 40 minutes. 
This clock update which can be likened to going on daylight 
saving time, only 2 hours and 40 minutes worth of change in- 
stead of 1 hour of change as we do on daylight savings time, 
will occur at 65 hours when the crew will have completed all of 
those flight plan activities up through 67 hours and 40 minutes. 
This simply involves setting our clocks at 65 hours in the Control 
Center and aboard the spacecraft at 65 hours, moving them ahead 
to 67 hours 40 minutes. Then, barring any further changes in the 
mission timeline from that point on, the elapsed time clocks 
which are used as the cue to flight plan activities, should 
agree with the flight plan and events that - in the flight plan 
are called out for a certain time will happen at that time on 
the elapsed time clocks in Mission Control and aboard the 

APOLLO 17 MISSION COMMENTARY -12/9/72 GET 54:51 CST 0630 MC 230/2 

spacecraft. This is a convenience factor. The other alterna- 
tive would be to go through the flight plan and change all of 
the flight plan times to agree with the clocks. We simply find 
it easier to change the clocks and avoid having to make all

APOLLO 17 MISSION COMMENTARY 12/9/72 07:30 CST 55:57 GET MC231/1 

PAO This is Apollo Control at 55 hours 

57 minutes. We're about 30 minutes away from the scheduled 
crew awakening time. And we've seen no signs of activity 
aboard the spacecraft at this point, however, we could hear 
from the crew almost any time between now and the next 
30 minutes. And if we haven't heard from them within about 
30 minutes we'll be putting in a call - a wake up call to 
the crew. Here in the control center the next team of 
flight controllers beginning to come on duty. Flight 
director, Neil Hutchinson, will be relieving flight director, 
Gene Kranz. And the spacecraft communicator on the upcoming 
shift is to be astronaut Gordon Fullerton. He'll be replacing 
CAPC0M, Bob Parker. Apollo 17, at this time, is 62 thousand 
415 nautical miles from the moon and traveling at a speed of 
some 3 thousand 280 feet per second and we show a range to 
Earth now of 170 thousand 6 hundred 50 nautical miles. We'll 
bring up the lines and monitor lines at this point for any 
call from the crew. At 55 hours 59 minutes this is Apollo 
Control, Houston.

to wakeup zero mark. We're waiting for the spacecraft to rotate 
through the next best OMNI antenna, before we make the wakeup call.

CAPCOM Good morning, Apollo 17, it's Houston, over. 

PAO Apparently the crew has not turned on the 

downlink on their transmitter. That was the University of 
Kansas J-Hawk Fight Song, which is Ron Evans Alma Mater. 

CAPCOM Apollo 17, Houston. Good morning.

can get them to turn on the transmitter. 56:45 ground elapsed 
time standing by. Here we go. (Jayhawk Fight song) 

CAPCOM Apollo 17, Houston. Good morning. 

Are you with us this morning? 

PAO As they say in the entertainment music 

business, one more time. We're going to send crew alert and 
when we see the voice up carrier up we're going to roll the 
tape again, the Jayhawk Fight song. The crew is very sleepy 
this morning or else they have their volume turned down where 
they can't hear the music. At 56:49 standing by, this is 
Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/9/72 08:22 CST 56:49 GET MC234/1 

PAO We are now sending crew alert. Gene Cernan's 

pulse rate still at about 49 which indicates the klaxon didn't 
wake him up. No indication yet that the spacecraft transmitter's 
has been turned on. 

PAO This is Apollo Control. Apparently the crew 

either does not have their volume turned up enough to hear the 
calls from the ground or perhaps the ear plug has slipped out of 
the ear of the crewman who's to monitor last night which I 
understand was Evans. Therefore, about every 10 minutes the 
Capcom is going to give a wake up call to the crew again in an 
attempt to raise them. Spacecraft Communicator Bob Parker is 
- has unplugged from the Capcom Console and is being replaced 
by Gordo Fullerton. And when we see on telemetry that the voice 
subcarrier from the spacecraft has been turned on, we'll play 
the old fight song again: Jayhawk Fight Song, University of 
Kansas. And, eventually we may get these sleepheads awake. At 
56:58 ground elapsed time, Apollo 17 is 60 471 nautical miles 
out from the Moon, approaching at a velocity of 3 2 85 and our 
slant range in nautical miles from the Earth to the spacecraft 
is 171 985 nautical miles. Standing by at 56:58, this is

pitched tone, that perhaps even with the earplug out they would be 
able to hear it from a fairly good distance. Presently, Apollo 17 
is 59 6 82 nautical miles out from the Moon approaching at a

SC Okay, with respect to food, let's see, 

we gave you a intermediate report yesterday. Do you want 
that repeated? 

CAPCOM Negative. 

SC Well, I'm not sure I can differentiate 

what I said yesterday so I'd just better give it all to you. 
This is yesterdays complete report. 


SC CDR was scrambled eggs, 3 bacon squares, 

peaches, pineapple-grapefruit drink, peanut butter, jelly, 
bread, chocolate bars, orange drink, apricot, that's dried 
apricot, 1 frankfurter, a third of a fruitcake, half a beef 
steak, butterscotch pudding, orange drink and tea. 

CAPCOM Okay, we got that. 

SC Let me know if I'm too fast for you. 

CAPCOM No, we've got it all on tape. Go ahead. 

SC Okay, with respect to food yesterday - 

LMP , scrambled eggs, 4 bacon squares, large pineapple drink, 
cocoa, potato soup, 2 peanut butter, 2 jelly, 2 bread,

orange juice, cocoa, peanut butter, jelly, bread, cherry bar, 
citrus beverage, fruitcake, butterscotch pudding, orange drink, 
turkey and gravy, 2 frankfurters and tea. You might say he 
was a little logy. Okay, CMP PRD 15027, 7 and let's - make 
that 8 hours of very good sleep, he claims he didn't get to 
sleep for awhile. Seconal and he's had 5 containers of water 
since the last reporting.

CAP COM Jack, in future reports, if it's any easier 

we can go to negative reporting. If you're fairly close to the 
menus, just tell us the differences, whatever is easiest for you 
is fine with us . 

SC Okay. Well, now that we're eating well, that 

may be the best way to do it. 

CAPCOM Okay. I have your consumables status, if 

everybody that's interested is listening. 

SC Go ahead, Gordon. 

CAPCOM Okay. Your RCS is running right along at 

1.3 percent above the flight plan line. On your cryos the 02 tanks 
2 and 3 are right on the line. Tank 1 is still as before about 
4 percent below the line, but looking real good. On hydrogen, 
you're a little above on 1 tank, on tank 2; a little bit below on 
tank 3, but the average is right with the flight plan lines. So 
consumables look good. Over. 

SC Okay. That's good to hear. 

sc And, I see that old SPS oxidizer pressure 

has dropped some more. I guess the helium is working it's way 
in there, or out of there. 

CAPCOM Okay. That's the way it looks to us. 

CAPCOM One final thing. Management has informed me 

that since you've been so late getting to work this morning, we 
are going to have to dock you all at a day's annual leave. 

SC All of us ! I can understand, I can understand 

that for the Commander, since he's always the Commander (garble), 
but I do not understand why the LMP loses an hour. 

SC Hello Houston, this is America. 

CAPCOM Hello Geno, good morning.

CAPCOM Okay. First a look at the weather in the local 

area. It's going to be mostly cloudy through Sunday, with a chance 
of showers here today, but much warmer. I'll have to wait until 
we get through the OMNI switch here and then I'll be back with you. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 10:27 GET 58:54 245/1 

CAPCOM Okay, 17. Continuing on with the weather, 

it should get up to the upper 60's here in Houston today. It 
was foggy when I came to work, but understand the sun is out 
now and the fog is burned off. On the International-National 
scene, there's another reported snag in negotiations between 
Dr. Henry Kissinger and North Vietnams Le Due Tho. The two 
have discussed the peace terms since Monday, but so far little 
news concerning the talks has been released by either side. 
They meet again today. A judge in the Pentagon Papers trial 
on Daniel Ellsburg has declared a mistrial. Judge Matt Burn 
has asked that a new jury be selected. Both sides in the 
cases must now go back to the beginning and prepare their 
arguments again. Former President Harry Truman is still 
hospitalized with a serious heart condition. Although listed 
in critical condition, the 88 year old former Chief Executive 
has shown some improvement, according to his daughter, 
Margaret Truman Daniel. President Nixon has completed selection 
of his new cabinet by announcing that he will keep Richard 
Kleindienst as Attorney General. There will be a number of ma j o 
changes, though, in upper levels of the Justice and Interior Dep 
ments. Life Magazine will be no more as of the end of Dec- 
ember. The pictorial magazine lost over 30 million dollars 
during the past four years. No doubt some of the final 
pictures to appear in the famous 36 year old publication 
will be those of the Apollo 17 mission. An airliner crashed 
at Midway Airport in Chicago, Friday. Of the 61 persons 
aboard, only 18 survived the crash. In other national and 
international highlights, unemployment figures show a drop 
to the lowest level in two years. 5.6 billion dollars has 
been released by the federal government in the first revenue 
sharing payment to the state and local goverments, and the 
NATO Foreign Ministers have urged the Soviet Union to cut 
down troop strength and allow freer movement of people over 
the east-west borders. In local and regional news, new hi- 
jack control devices have been installed at Houston Inter- 
continental Airport. The new metal detectors are being in- 
stalled in many airports around the United States. New 
inspection procedures will also begin in January of all hand 
luggage carried aboard airliners. And on the sport page, 
Al Conover is not going to return to Wake Forest as rumored. 
The Rice coach has met with University President Dr. Norman 
Hackerman to discuss a firm five year contract agreement. 
Professional football highlights today's sports, the "Over- 
The-Hill-Gang" from Washington with Billy Kilmer and Larry 
Brown will take on the Dallas Cowboys at Texas Stadium in 
Irving. The Cowboys will no doubt go with Craig Morton at 
quarterback. Dallas can insure itself of a "Wild Card" slot 
in the playoffs with the Redskins, if they win. For Dallas 
it's a revenge game. The Skins have won nine straight.

CAPCOM Johny Bench, the Cincinnati Reds all- 

everything catcher, has been hospitalized for tests. X-ray 
showed a spot on a lung. Doctors feel sure the lesion is 
benign, though. The University of Houston basketball team 
takes on Xavier tonight. The Cougars, with four wins and 
one loss, will face a Xavier. team that likes to play slow- 
down basketball. The Houston Rockets beat the Portland, 
Oregon Trailblazers last night in Hofheinz, 114 to 108. The 
Big Eight Athletic Conference has joined the Big Ten and the 
Ohio Athletic Conference in breaking relations with the U.S. 
Olympic Committee. Back in Houston again, Bill Peterson, 
the Oiler Coach, says he's not planning on new Assistant 
Coaches. He says the Oilers need more togetherness with 
their coaches, not new ones. And a final item, the Des Moines, 
Iowa Post Office was emptying a mail pouch. One package 
fell on the floor, broke open, and spilled all over the place. 
The contents were Postal Service instructions on how to wrap 
and mail packages to insure safe transit and delivery. 

SC Very good news report, Gordo - 

SC Yes, that crash in Chicago, can you tell 

me a little bit more about it? 

CAPCOM I read real briefly in the paper, just 

before I came in that it did crash in a populated area, so 
it's a very brief report. I don't think the final details 
have been published yet. I'll check to see if we've got 
anymore in. 

SC Okay, and I guess you know where - at 

least my wishes go for that Cowboy game, don't you? 
CAP COM I'm not sure that I do. 

SC I'll just let you make an assumption. 

CAPCOM Okay, we've got an antenna switch coming 

here . 


APOLLO 17 MISSION COMMENTARY 12/9/72 10:34 CST 59:01 GET MC246/1 

CAPCOM 17, Houston. I have a little more on 

the plane crash, if you'd like to hear it. 

SC Yes sir, Gordy- Go ahead. 

CAP COM Okay. It was a United Airlines jet, 

61 people aboard, and it crashed into a south-side Chicago 
neighborhood while trying to land at Midway. Most of the 
55 passengers - they were - I'm not sure I'm getting all 
the numbers right here but it said here that most of the 
55 passengers were found dead in the debris and it was a 
Boeing 737 about a half a mile away from the airport. One 
of the victims was representative George Collins, a Democrat 
from Illinois, who was returning from Washington to organize 
a children's Christmas party. The weather, at the time, was 
500 foot ceiling and one mile visibility and sleet and snow 
were falling at the time. There were no reports that any 
occupants of the houses were injured or killed. I turn back 
to the back of the paper, here. A United spokesman said one of 
the six crew members, a stewardess, was among 16 persons admitted 
to Holy Cross Hospital. She said there were 2 infants among the 
passengers. Jet apparently missed runway 13 at Midway on - 
that cruised over the neighborhood of bungalow homes at 
heights of 500 to 1000 feet and then with his nose up and 
tail down tore into the dwellings. Witnesses said the plane 
scraped the roofs of 2 bungalows and sheared through 6 houses, 
setting them aflame. The fuselage of the airliner split but 
the nose remained intact. A tail section was sticking out of 
one house. The following airliner sheared through utility 
lines and a 2 square mile area was blacked out. Telephone 
service was knocked out. A power company spokesman said 
5000 homes were affected. 

SC Okee-doke. 

CAPCOM And a little news about your trajectory. 

Since the midcourse 2 you've been looking real good. You've - 
you're homing in on 53 1/2 mile parallel. We're discussing 
midcourse 4, which if we do it at all, is going to be very 
small. Its looking like about a foot and a half per second right now 
And I guess if we do it, it will only be because it will save 
us Delta V at L0I. Over. 

SC Okay, I was just looking. Those dumps 

really knocked us for a loop, didn't they? 

CAPCOM Yes, it - it's driving your PTC out. 

SC Yes, we're at almost 40 degrees, now. 

SC Gordy, has the temperature been pretty 

cold down there? 

CAPCOM Here in Houston it warmed up considerably 

last night - yesterday afternoon and last night and this morning 
it's probably in the 60's somewhere. 

SC Garble. 


APOLLO 17 MISSION COMMENTARY 12/9/72 10: 44 CST 59:11 GET MC 247/1 

PAO This is Apollo Control, 59 hours 11 minutes 

ground elapsed time. Apollo 17 currently is 56 148 nautical 
miles out from the Moon closing on the Moon at 3284 feet per 
second. Distance from Earth is now 175 441 nautical miles. We'll 
continue to leave the line up as we proceed into today's activities 
which includes another activation and check out of the lunar 
module and hopefully today the communications noise will be 
somewhat less than it was yesterday. At 59:13 standing by, this 
is Apollo Control. 

CAPCOM 17, Houston, I have some words about the 

troubles we had during the LM comm checks yesterday, if you have 
a free moment to listen. 

SC Go ahead, Gordy, we're listening. 

CAPCOM Okay, we think we've got a pretty good handle 

on what the problem was and that was that the - the LM communica- 
tions gear, we think was jumping on the voice sub carrier 
rather than the main carrier and the symptoms that we had point 
to that. What would happen is when I would try to transmit that 
it would lose lock soon as I put modulation on the voice 
sub carrier. During the checks today, we're gonna try to verify 
that the system is indeed working okay and we can do it without 
any changes in the onboard procedures by - purely by procedures 
that will be handled at the ground site and here at Mission 
Control and so that's what we're planning to do. We really don't - 
the problem that happened has been seen before evidently and it's 
not that unusual. We really don't think there's anything wrong 
with the onboard equipment. Over. 

SC Sounds good, Gordy. We'll just take her 

slow and easy when I get over there today and make sure we 
understand it. 

CAPCOM Okay, Jack, and there's real no voice check 

scheduled and we don't think any are required. We can tell what 
we need to without any voice checks again. 

SC Gordy, you're breaking up, talk to you as 

soon as we get another omni . 


SC While I got, I took 3 pictures of the Earth. 

Thought I might have moved one of them and we're on frame 145.

closed the Lunar Module hatch and it should be reinstalling the 
probe and drogue assemblies. And finally the Command Module 
hatch, thereby closing out the tunnel. Apollo 17 now 177, whoops 
would you believe our space digital have gone back to Earth 
reference momentarily. At any rate the spacecraft is 177 966 nauti- 
cal miles from Earth, traveling at a velocity of 2652 feet per 
second in - with reference to the Earth. And as soon as the 
space digital display goes back to the Moon reference, we'll 
read those numbers off. We're waiting for the call from the 
call crew that they have completed stowing or installing 
the probe and drogue assembly in closing out the tunnel. At 
61:51 standing by this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 13:24 GET 61:51 257/1 

CAPCOM America, Houston. We'd like to terminate 

the charge on battery B. 

AMERICA Okay, stand by 1. Okay, we'll get that 
in a minute, Gordon. 


AMERICA Okay, Gordo, the charge should be termi- 
nated on bat B. 


AMERICA And 7 alpha is still .6. 

CAPCOM Roger. 

AMERICA Okay, Gordie, I'm looking around, but I 

can't figure out what that master alarm is? I didn't see 

any 02 high flow and I didn't see any lights and we did get 
it down in the LEB. 

CAPCOM Okay, Gene. 

AMERICA And there it is again. 

CAPCOM Roger. 

AMERICA And again. 

CAPCOM Roger. 

AMERICA Okay, I saw SPS pressure blink on that 

one . 

CAPCOM Roger. 

AMERICA Yes, Gordie, keeps triggering continually 
on SPS pressure. 

AMERICA Yes, I can reset it and a minute later 

she's coming up with a blink on SPS pressure. 

CAPCOM Okay, Gene. We think it's the, well, 

we're sure that it's the oxidizer pressure, it's right on 
the trip limit, we're almost certain it's due to helium 

AMERICA Yes, we're reading 155 right now. 

CAPCOM Roger. 

AMERICA Okay, Gordie. We got the SPS pressure 

light on steady now. 

CAPCOM Roger. 

CAPCOM America, Houston. If you give us ACCEPT, 

we'll give you a new state vector. There's not much wrong 
with the one you've got but we're just going to teek it up. 

AMERICA Okay, Gordie, you've got it. 

CAPCOM One other question, do you have the LM 

closed up, now. We're seeing some heater currents that are 
a little higher, indicating maybe the lights still on, we're 
just trying to understand where the LM is at the present 
time . 

AMERICA Okay, I just closed the hatch, just 

about the time you started talking there. 

CAPCOM Okay, we'll take a look at the temps 



APOLLO 17 MISSION COMMENTARY 12/9/72 CST 13:49 GET 62:16 MC-258/1 

CAPCOM America, It's your computer and we did 

th e VE RB 6 6. 


AMERICA Hey, Gordo, what's the trend in thinking on that 

SPS light, to leave it lit or to bump the pressure up? 

CAP COM Ed Mitchell must be at work. Because we 

were just talking about that subject. I'll call you when - with 
a final decision. 

CHALLENGER Okay. And Ron has put - has closed LM 

hatch, put the drogue in and he put the probe in and he's putting 
the CSM hatch in as a one-man exercise suited. So, he's doing 
the whole thing and he's still in his suit. Our suits are 
s t owed. 

CAPCOM Okay, Gene, we got one question here, that - 

just waiting for a convenient time to ask, and I was wondering is 
with reference to the wakeup problems we had this morning. If you 
clearify just exactly why Ron didn't hear our crew-alert 
master alarm, you know exactly why? 

AMERICA Well, it's not the Seconal. As much as I 

hate to admit it, the power audio tone was off (chuckle) in my 
headset . 

CAPCOM Okay. We kind a suspected that - - 

AMERICA So, - Okay, that lets you rest a little bit 

easier. And just to prevent something like that from happening 
again, or if it should happen again, what we'll do we'll hook up 
the tone-booster, which we didn't have hooked up last night. 

CAPCOM Okay. And we concur positive. 

AMERICA Yeah. I woke up and I saw that light there 

and I thought gee whiz, I just got it in time until I tried to push 
out that caution and warning master alarm. And worked the end 
of my finger. 

CAPCOM (Laughter) 

AMERICA I was also in a sleep restraint and upside 

down was a zipper in the back and I had a little problem in 
getting my hands up to start with also. 

CAP COM Ro g . 

AMERICA Hey Houston, cabin repress is back to both 

now. I mean emergency cabin repress. 
CAPCOM Roger, Ron. 

CHALLENGER Gordo, if you don't have any objections, 

we'd like to go ahead and secure the high-gain and go on a 
PTC while Ron's doffing his PGA. 

CAP COM Let me check and see if we have any. 

CAPCOM Sounds good to us. Go ahead and - per 

flight plan and spin it up. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 13:49 GET 62:16 MC-258/2

CHALLENGER Okay, Gordy. You want to leave the high-gain 
until you call?

Hello, Houston. You read? 
Loud and clear. 

Okay, now that we got another look at 
like Houston might be right on the fringe 


of either being clear or clear, the entire Gulf is pretty 
nice. Florida looks pretty clear and Mexico looks pretty 
clear. There's a big air mass of clouds that looks like it 
picks up somewhere around the coast at Houston and heads on 
up north and then covers most of the midwest and the east 
from about the middle of Mississippi, Alabama and Georgia 
on north. It's clear enough now to even see the coral reefs 
down off of Florida. And it looks like west Texas is probably 
also pretty clear, at least in a run from east to west. We 

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 14:16 GET 62:43 259/2 

AMERICA Can see Baja, and on up the coast of 

California up north. 

CAPCOM Okay, sounds like the whole crew is 

turning into weathermen. 

AMERICA It's one of the better views we've had 

of the states, I think, even though we're quite a ways out. 

CAPCOM Roger. Looks like your sub spacecraft 

point is just about at Peru right now. 

AMERICA Yes, it looks like we're looking straight 

down in the center of South America, pretty close to what 
you're saying. Gordie, you want to bring us up to date 
briefly on how you plan to handle this time update again? 

CAPCOM Okay, I'll do that. But let me practice 

before I start here, just a minute. 

AMERICA Okay, I'm primarily interested in those 

parts of the flight plan which we're going to eliminate. 

CAP COM Okay, just one second. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 14:29 GET 62:57 MC-260/1 

CAPCOM Geno, I'll read you the PAO release, they 

summed up pretty well, and I'll just use their words here. 
The time has been made up in two increments. The first one of 
1 hour and 45 minutes in the flight plan. The crew activities 
were jumped ahead by 1 hour and they essentially began doing those 
things that were called for 1 hour later in the flight plan. 
They will again jump ahead 1 hour and 40 minutes and that will 
occur in 65 hours. By that time they will have completed all 
those activities required up thru 67 hours 40 minutes in the 
flight plan. Or in other words, they will have completed all the 
activities required to get them into Lunar Orbit 2 hours 40 minutes 
early and in order to make the clock then agree with where the crew 
will be in the flight plan we'll jump the clocks ahead 2 hours 
and 40 minutes. This clock update, which can be likened to going 
on day light savings time, only 2 hours and 40 minutes were in 
the change instead of one hour of change as we do on daylight 
savings time will occur at 65 hoUrs when the crew will have 
completed all of those flight plan activities up thru 67 hours 
and 40 minutes. This simply involves setting our clock to 65 
hours in the control center and aboard the spacecraft at 65 hours 
moving them ahead to 6 7 hours and 40 minutes. Then by any further 
changes in the mission timeline from that point on the elapsed 
time clock which are used as a cue to flight plan activities 
should agree with the flight plan in events that in the flight 
plan a call out for a certain time will have been at that time 
on the elapsed time clocks in mission control and aboard the 
spacecraft. This is a convenience factor. 

SC You're lucky we're going to lose an OMNI. 

CAPCOM Okay. I'll hold on there for the rest. 

SC Gordy, never mind, I think I got the gest of 

i t . 

SC Did you give up Gordy? 

CAP COM Okay. What we're really going to do really 

is simple. At 65 hours we're going to do the update of 2 hours 
and 40 minutes. And the procedures are shown in the flight plan 
at 67:35. There just happens to be really no, no activities we 
have to reschedule in the intervening time. So, after the update 
is complete, we'll be right on the flight plan, both time-wise 
and activity-wise. Over. 

SC Okay. We're looking at it. 

SC And I have to squeeze my shave in somewhere 

else, I guess. 

CAPCOM Hey, Gene, Houston. 

SC Go ahead. 

CAPCOM Hey, you got a break - cast the time vote 

which is the best description the water-bag or the cloth one. 
SC Oh yeah, now I remember. 

SC We got a little - give a little credit on 

this last one, I guess to Public Affairs. Because I don't think 
Gordo could have thought that one up all by himself. 

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 14:29 GET 62:57 MC-260/2 
SC Very diplomatic. 

SC Considering I was trying to do Charlie's 

technique step by step, I guess I got to give him little bit more 
credit from the gymnastic point of view. 

sc That sounded like one of Gordy's aircraft 

s che dules . 

SC Amen. 

PA0 This is Apollo Control at 63 hours 9 minutes.

CAPCOM Jack, we lost all of that due to the antenna 

switch, say it again. 

CAPCOM Jack we missed your last transmission. 

SG Gordy, you listening.- - 

CAP COM Due to the antenna switch. 

SC You say you got it or you're getting it. 

CAPCOM No we missed it. 

Sc Okay, I said you can look right down at 

the Cape area, that's the Cape that we know, in Florida and it's 
little disheartening because the last time I was up here looking 
back from this angle we were moving another Saturn V for another 
Moon trip out on the pad already. I guess they're working 
pretty feverishly out there on the - - 

PA0 This is Apollo Control at 63 hours 11 minutes 

ground elapsed time. Charlie Duke was on the spacecraft's communi- 
cators console for a while there, discussing the clock update 
description that had been read up earlier by Gordo Fullerton asking 
for a judgement on the part of the crew as to whether that descrip- 
tion was better than - - 

SC Jack, I think Gene was probably right. You 

got some, probably scattered cloud weather, but not very far 
away from you there's a pretty heavy mass of clouds. It may be 
the forerunner of that dry cold front you were talking about 
yesterday, which I can see stretching over into Synora, but where 
it hits the state side, you've got quite a mass of clouds 
associated with it and looks like they're moving in your direction. 

CAPCOM Okay, Jack thanks for the warning. 

SC Clear behind us in Arizona to Mexico and 

maybe Southern Colorado. It looks like there may be another 
front stretching, or maybe it hits Northern Arizona and Utah and 
up through Northern Colorado, and on in to Canada. 
Turning Northeast. 

CAPCOM You're calling it right on Jack, I'm looking 

at the surface chart and that's about what we see. 


APOLLO 17 MISSION COMMENTARY 12/9/72 14:46 CST 63:13 GET MC261/1 

CHALLENGER Looks like a low might be developing 

on that one - a wave up in Northern Colorado and - although 
the clouds are a little hard to read. 

CAPCOM Roger. 

PAO And that was lunar module pilot, Jack 

S chmi 1 1 . 

CHALLENGER Up our zero page point, about 20 degrees 

west of Bolivia, are some - are zero - zero page point and 
it is quite a bit brighter than yesterday and looks as if 
and more general as if maybe the seas have picked up in 
that region a little bit. 

CAPCOM Roger. 

PAO Some more real-time weather reporting. 

CHALLENGER Features is developed - as I see - 

developed in the South East Pacific just north of the Ross 
Sea and that is a very striking mushroom pattern on a very 
large scale. It has north-south cloud streaming streamers 
from the Ross Sea and when it gets up about the lattitude 
of Tierra Del Fuego but quite a bit west of that land it branches 
out to the east and west in a large mushroom pattern. It 
looks like the top of that mushroom may be a curved cold 
front that's pushing it's way up into the southeast Pacific, 
It currently - the eastern edge of that front is probably 
10 degrees longitude from Tierra Del Fuego and it looks like that 
land is in southern Chili and picking up high clouds, 
probably associated with that front's movement. 

CAP COM Roger. 

CHALLENGER I'll get some shots of that next time 

around. That's a spectacular pattern. You almost get the 
feeling that the cold air mass moving out of Anartica streams 
for a while north-south and then it picks the cloud patterns 
change and it starts to migrate - the winds start to change 
from east to west. Maybe that's where it encounters the 
jet stream. 


PAO This is Apollo Control. Going through 

an antenna switch at the present time. 

CAPCOM America, Houston, I have a couple of 

miscellaneous items here. 

AMERICA Okay, go ahead. 

CAPCOM Okay, we'd like you to disable B2 and 

D2 just for a drill. 

SC Oh, thank you Gordo. 

CAP COM Also, the she tank looks exactly 

nominal as far as the rise rate goes to us. 

SC Can't argue with that. 

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 14:46 GET 63:13 261/2 

CAPCOM And to summarize your film by your situa- 

tion have three magazines KK LL and MM budgeted for the scheduled 
photos such that they have only 5 19 and 1 respectively 
frames left over after you've done all the schedules pictures. 
And november november we think has just has nine frames remaining 
now. The two nonscheduled magazines are 00 and PP 160 frames 
each. Those are the ones provided for optional use. We 
have 44 additional frames scheduled out of November November 
scheduled during lunar orbit. There is only 9 left in it 
now so we'd like to save at least 60 frames out of either 
oscar os car or pappa pappa the two optional magazines to 
cover the scheduled frames. Guess what we're saying is that 
there is no problem we've still got plenty of film, but you 
will have to use some of your optional mags for scheduled 
pictures 60 frames is what we want to save. 

SC Okay, mighty fine Gordo plan on oscar 

oscar for that magazine.

Schmitt, who is a professional geologist, put on his hat as 
an amateur meteorologist and described some of the global 
weather systems visible from their vantage point out beyond 
180 000 miles from Earth. Still up live and standing by at

SC Gordy, this is Jack. 

CAPCOM Go ahead, Jack. 

SC I, Cal Tech will never forgive me, I'm little 

hesitant on my elementary optics, but I just put Ron's 
polorizing filter in front of the monocular looking at the 
Earth and rotate 90 degrees and from max to min in terms of 
brightness, there's a remarkable change. I suspect that 
means that the Earth is polorizing light enough to see it. 
The main thing that happens is that the oceans get consider- 
ably darker when I rotate the filter towards the dark position 
anyway. The continents don't seem to show any obvious change 
but the oceans and the geoface point darken, oh I would guess by 
a factor of 2 in brightness, maybe that an extreme, but I 
think it's th a t . 

CAPCOM Ah, Jack, I was just trying to think of 

a reason, is it uniform change over all ocean areas or is it 
more of a change in some areas than others? 

SC Well, I'd say that the sub-solar point shows 

the greatest change, but you can still - the geoface point 
shows the greatest change. But all the oceans get darker. 

CAPCOM Very interesting. We are just about 

to switch OMNI.

started. It's now 7-0, Cowboys. They scored the first time they 
got their hands on the ball. 

SC Okay, I think we got most of that. It hap- 

pened again, though. Did you say it was 7-0 Cowboys? 

CAPCOM That's what I said. They scored the first 

time they got the ball. It's -- the game's just about 5 minutes

somehow, when we put the suit on the water bag had gotten turned 
sideways, I guess is the way they explain it. It got turned 
sideways such that the suction tube was crimped sideways. And, 
as a result, there is no way that you could get any water to go 
through the tube. 

CAPCOM Okay. You're talking about the problem we 

had there just before launch, right? 

SC That's affirmative -- prelaunch. Okay, and 

for your information, the PTC looks good it ought to, hold.

That' s great. 

SC Gordy I, this is Jack, I just tried the red 

filter on the front of the monocular, and about the only major 
thing I noticed was that the cloud patterns over the land masses 
seemed to be enhanced. The contrast between cloud and land, parti- 
cularly green land, is enhanced. Otherwise, all it does is make

SC Houston, 17. 

CAPCOM Go ahead, Jack. 

SC Yeah, about this ice pack in the Ross Sea 

the, as I remember a couple days ago, there were two clear 
areas, triangular in shape and quite elongate, that were 
projecting out into the sea from the intermost part of the 
bay or the, from the continent. Today those are not apparent 
or at least the first look I made. And it looks like there 
is an elongate more irregular clear area that is roughly 
parallel to the Antarctic coast line within the sea itself. 
We'll check that a little more closely and see if that's 

CAPCOM Okay. Seems like kind of a quick change 

for something like ice. Doesn't it? 

SC Yeah, and that's what bothers me. That's 

why I wonder if I'm not being fooled by cloud patterns or 
something . 

CAPCOM I'm looking at a satellite picture here 

which I guess is around 12 hours old though, but over to the 
east of Australia, maybe about a continent width east of Australia 
there is really striking long frontal system, striking 
because it's so long and so straight, sort of west northwest 
extending west, northwest and east, southeast turning. 
Can you see that? 

SC Gordo, are you there? 

CAPCOM Yes, sir, right here. 

SC Okay, now, Jack and I may be talking about 

two different frontal systems or patterns; but the one I 
think you might be referring to is the one I referred to yester- 
day as a ruffled parrot beak, actually two of them tied together 
one starting up probably southeast of Australia and then 
heading down with a long arcing frontal system to another 
clockwise rotational parrot's cone I should say, down 
around near the tip of South America between it and Antarctica. 
There is one strong tributary front heading up to the north 
northwest from the western side of this big arctic frontal 
mass. And I think that's probably what you're referring to, 
I'm not not sure, I can't quite see, Australia coming up 
over the horizon yet. 

CAPCOM Okay. I, my picture cuts off right about 

oh, two-thirds of the way south in Australia, that latitude, 
so, most likely we're talking about the same thing; but I 
can't verify the southern part of it. 

SC There is some tremendous - western side 

of that curve front, is a tremendous clockwise rotational 
air mass, it must cover hundreds of square miles. The one 
down near the continent of Antarctica, down there, near the 
tip of South America, seemed to be squashed slightly as if 

APOLLO 17 MISSION COMMENTARY 12/9/72 15:47 CST 64:13 GET MC266/2 

there is possibly some squashing or effect coming off the 
South Pole area near Antarctica. I think, if I turn around 
and look at it the way Jack was looking at it, it's a cap of 
a mushroom. Only instead of simply curving in underneath 
the cap it has clockwise rotations on both sides as it curves 
unde r .

PAO This is Apollo Control at 64:26 Ground Elapsed 

Time. The space digital's, meanwhile, has come back to Moon 
reference numbers. Our distance now from the Moon is 
45 955 nautical miles. Velocity 3300 feet per second. And the 
Earth is 183 365 nautical miles behind Apollo 17. Shift change 
press conference at 4:15 with Flight Director Neil Hutchinson. 
Chuck Lewis taking over now, with his team of flight control- 
lers at 64:27 and continuing to stay up live on the Air- to-Ground 
this Apollo Control. 

SC Gordy, I just took 2 pictures of the Earth at

of Australia. 
SC Okay 
talking about, on either

Yes. That mushroom pattern we've been 
end, either end of the cap, the mush- 
major cyclone circulation system. And 
one case or trending in one case to the 

northwest and the other to the northeast, there are linear cloud 
patterns. Gives it a very symmetrical and a striking appearance. 
I hope it shows on those pictures. 

Okay, it doesn't show on the one I got. Maybe 
have that one. Because it's cut off on this 

later version will

Hey, Gordo, 
Go ahead. 

To put this update in simple terms in 65, 
clocks, you'll update us to about 67:40, right? 
CAPCOM That's affirmative. 

SC Does that mean we have to eat 2 hours and 

40 minutes earlier? 

you got me there. I, you haven't been eating, 
breakfast. Is that right? 
yes sir. We just finished. We'll take 
feel I've spending my life here eating.

Oh , 
but I 

Well, we'll leave it up to you on this 

Okay, I think we'll take a jab at supper here 
per the flight plan. 
Allright . 

Gordy, the whole suiting operation, I was 
with. Jack and I both got in our suits very easi- 
we went into the LM and that's where we zipped 

APOLLO 17 MISSION COMMENTARY 12/8/72 GET 64:26 CST 16:00 MC267/2 

SC each other up and we really had little or no 

trouble. We took our time. We got all configured in terms of 
changing our pockets around and whatever else we need to do. And 
actually I think it's much easier to get suited than it is to get 
unsuited, personally. 

CAP COM Okay, sounds good. 

SC Ron stayed suited and did the entire tunnel 

work. And then went, did it by himself and then totally doffed 
his suit and stowed it by himself also to sort of extend that little 
(garble) exercise. 

CAPCOM Roger. 

PAO This is Apollo Control at 64 hours 43 minutes. 

Change of shift News Conference is ready to begin in the News Center 
briefing room. We'll take this line down now and tape for the dura- 
tion of the News Conference. 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 67: 45 CST 16:39 MC268/1 

PAO This is Apollo Control at 67 hours 45 minutes. 

We have advanced the Ground Elapsed Time clock in the Control Cen- 
ter and on the Flight Plan are operating at the point indicated for 
that time. In the News Center, the monitors, the actual GET time 
will be shown on the Time Base 5 clock. The GET clock will now show 
the Flight Plan GET time. And in the Flight Plan, the Central 
Standard Times and GET times listed will now agree and be correct. 
We accumulated a few minutes of tape during the News Conference and 
we'll play that for you now. 

CAPCOM Jack, Houston, halftime score is 28 to 3, Cowboys. 

SC Keep talking, Gordo. 

CAP COM Okay, I'll keep talking. The, Ron, when you get 

to the ALFMED board out there, you'll see some tape around the emul- 
sion field, so there three rectangular areas in front of your eyes 
and to either side that contain the photographic emulsion. This 
tape is around the edges of each of those three areas to help seal 
out light leaks. You haven't seen it before. Leave the tape on 
there. Don't pull it off. Over. 

S C Ok ay . 

SC Gordy, just took a series of pictures of the Earth 

with the 35 millimeter using the polarizing filter in the two posi- 
tions. And the frame count is now 39. I took 6 pictures. And 
with the filter on the first of each pair, in the down position. The 
second's in the up position and I changed the F stop. The first 
set at F4 , the second set at F2 , and the third set at F8. 

CAPCOM Okay, we got all that Jack. 

SC And Gordy, you might ask one of the experts 

around there is the light meter in the 35 millimeter integrating 
over the interior spot or over the hairline spot, The larger one? 

CAP COM Okay, I'll ask. 

SC It acts as if it's the interior one, but 

(garb le) . 


CAPCOM Jack, answer to your question there, there's a 

center spot is weighted for 60per cent of the reading and the 
rest of it for 40 per cent. Over. 

SC Okay. That makes sense. That would explain 

why the needle moved as I moved it across the series of spots. 

CAPCOM Roger. 

SC Gordo, we're ready anytime you are for that 

update and after we get the TFM and everything squared away, we'll 
go into ALFMED. 

CAPCOM Roger. Stand by on that, Geno, and we'll be 

with you in a minute. 

SC Hello, Robert. How are you today? 

CAPCOM Real fine, Gene. You're sounding great. 

SC Doing great out here. 

APOLLO 17 MISSION COMMENTARY 12/9/72 GET 67:45 CST 16:39 MC268/2 

CAPCOM Geno, we're ready for the clock update. We'd 
like POO and ACCEPT and we've got two loads to put In, so it will 

take a couple of minutes here. 

SC Okay, you got it? 

CAPCOM Thank you, Ron. 

CAPCOM Update on your fly by maneuver pad due to this 

clock update. Would you like to copy it? 

SC Stand by just one second. 

SC Okay, Houston. Go ahead with the fly by pad. 

CAPCOM Okay, stand by 1 on that. We 1 re done with the 
upload. The computer is yours, and we need a readout on the TFM. 

SC Okay, that's in work. 

CAP COM Okay, we've got the readout. 

CAPCOM 17, Houston. The data looks good and you're 
go to copy it and recommend you copy it in the Flight Plan sup- 
plement. And that's on page 1-43 of the supplement. 

SC Okay, Houston. We have it. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 16:45 GET 67:51 269/1 

PAO This is Apollo control we're back live 

on air ground now. 

CAPCOM And 17, we got that fly by pad now if 

your still ready we're ready. 

SC Okay, is this a full pad or just a change 

to the other one. 

CAPCOM Just a change Jack it's a change to NOUN 83 

the GET I and the change to the bottom line the GET 05 g just 
two ch ang es . 

SC Okay, go ahead. 

CAP COM Jack, if you'll just add 2 hours and 

40 mintues to each one of them that's it. The GETI is 081 
54 43 49 . The GET of 05 g 156 04 03. Jack I guess I read 
81 I was looking at the old pad it's 83 083 on the GET I. 

SC Your too fast for me I was just going to 

chew you out. 


Sorry about that Jack I got it around 

the room. 


083 (laughter) 083 54 43 49 156 04 03. 



S C 

Okay, Bob we got all of our clocks set 

onbo ard. 


Roger, understand. 


What was the exact amount of that update 

time ? 


2 hours and 40 minutes 2 plus 40. 


Okay, 2 plus 40 exactly thank you. 


Okay, Bob we're going to work up an 

appetite with 


ALFMED today. 


Ro ger. 


Hey, Bob maybe a little premature, but 

I don't think 

s o , 

but I think there was some good thinking 

into that update 

looking at the flight plan up until now, 

and where we 

go from here. I don't think we overlooked a 



Roger, like I said the other night we 

gave Tommy a 


star on that one. 


Except I think he and Rita got in cahoots 


A little soon for supper, huh? 


Yeah, we just finished lunch and it's 

about time to 


again . 


That's known as the simulator step ahead. 


Can you give us our distance from the 

Earth ? 


Roger, stand by. 


Are we about 5 000 miles closer now?

way . 

Don ' t you wish . 

Isn't that the way these step aheads work? 
Normally, yes but this one didn't work 

Jack, your at 183 000 miles. It's really 
flys when your interested in your work isn't 

Jack, Houston. Did you read my last call 

amazing How time 
it ? 

with the distance? 

PAO This is Apollo control at 68 hours 

1 minute. Apollo 17 is 183 211 nautical miles from Earth. 
Velocity is 20521 feet per second. The spacecraft communica- 
tor now is Bob Overmyer. Stu Roosa the backup command 
module pilot for Apollo 17 is also at the capcom console 
with Overmyer. 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 68:03 CST 16:51 MC270/1 

SC Houston, 17. 

CAPCOM Go ahead 17. 

SC Okay, Bob, we're getting ready for the ALFMED. 

I just took red filter and a blue filter picture, two pictures on 
frame 41 now, with a 35 millimeter. Pictures of the Earth and I 
took them one stop smaller, that is more open than the light meter said 
hoping to compensate for the small Earth. The Earth just barely fills 
the most inner, the innermost circle of the spot meter. Also 
a very strong band of cloud, shaped sort of like a narrow fir tree 
with a base about 20 degrees of longitude west of Baha, California 
that extends up, I believe, into the vicinity of Hawaii, and the 
top terminates in a very strong northern cyclone pattern. 

CAPCOM Roger, Jack. Was your magazine Sierra, Sierra' 

SC That's affirmed. Sierra, Sierra. 

CAPCOM Roger, Jack. And you say that cloud is right 

that cloud area is right near Baha, California? I've got a picture 
of it here in front of me, from one of the satellites. 

SC No, it's about 20 degrees west, longitude degrees 

west of that. 

CAP COM Yes. Okay, we've got it on the spot here. 

SC And maybe even more than that. Okay, maybe even 

more than that. It's, it might be as much as 40 degrees west and 
actually Hawaii may be on the west side of that. It's a little 
hard to tell. It's close enough to the LM that it's hard to say. 

CAPCOM Roger, Jack. I think I've got it on our map 

here. It shows a pretty heavy dense cloud area right now in that 
area you're talking about. 

PAO This is Apollo Control at 68 hours 7 minutes. 

ALFMED is Apollo Light Flash Moving 

SC For the ALFMED, CDR will be in the left seat, 

CMP will be in the center seat with the ALFMED. For our reporting 
when we get the VOX, we'll just call out our first names to shorten 
it and the comments following. And Jack will be recording. 

CAPCOM Roger. We'll be listening. 

PAO That's the Apollo Light Flash Moving Emulsion 

Detector, associated with the visual light flash phenomenon that 
most crews have reported on past missions, seeing points of light 
in their eyes, when their eyes were closed. There are a couple of 
theories proposed on the origin of the flashes. One is that they 
are caused by cosmic rays. The other is that they are high energy 
atomic particles which enter the eyeball or ionize upon collision 
with retina or cerebral cortex. The ALFMED is an emulsion plate 
device that Ron Evans will wear. It will cover the front and sides 
of his head and will provide information on time, strength and path 
of particles penetrating the emulsion plates. The other two crewmen 
will wear eye shields. This test will last for approximately an 
hour. And the data on the, recorded by the ALFMED device will be 
correlated with the crewmen's verbal reports on flash observations.

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 17:18 GET 68:24 272/1 

SC Change it. The other side is not very 


SC Mark, Gene I've got a series of random 

lines which do not appear to be the width of my field of 
view that are moving like a flashing horizon with thunder- 
storms on the horizon. Their dimly flashing and their moving 
across the eye from left to right and from top to bottom 
individually. Both eyes. It's stopped now. 

SC Mark, this is Gene again going from the 

upper left to the bottom right lines of the same sort of 
thing, dimly lit flashing horizon type flashes. But their 
linear. Their linear and they tend to come from either the 
upper left or the upper right and work their way downward. 
Now they've stopped. Both eyes. 

SC Mark, Gene again. Both eyes this time 

the same flashes on the horizon, but they don't seem to be 
moving out of both eyes. Tend to be up at the tops of both 
eyes. Just rapid sequential lightening like flashes. They've 
s t op pe d . 

SC Mark, Gene again. Similar type of flashes 

they don't seem to be moving, but their coming from the right 
of the right eye and from the upper left of the right eye. 
And I can actually see an outline of a curved horizon and 
the flashes are coming out from behind it. They've stopped. 

PAO This is Apollo control at 68 hours 

30 minutes. Distance from Earth 183 910 nautical miles. 

SC And I see peripherally out of my right 

eye. I cannot see these flashes, but I can see peripherally 
the right hand and upper right hand side of my right eye 
b eing lit up . 

PAO Distance 183 920 nautical miles velocity 

2 504 feet per second. 

SC Pardon? this last one? They were peri- 

pherally I couldn't see them all I know is that there was 
some light out peripherally out but a flashing glow. Oh 
man, there is a good one the left eye right in the middle 
it's almost a purple flash. It's still going right in the 
middle of my eye and it's coming out from behind a horizon 
that is almost. It starts out as a semicircle and then 
folds in to a point like on a pencil, and then it disappears. 
That's the horizon and the light is flashing from behind it. 
It's gone . 

CAPCOM Hey Gene, Houston. 

SC Go ahead. 

CAPCOM Okay, according to all our experts here 

the phenomena your describing is pretty much the phosphene 
effect sort of like when you rub your eyes or squint your 

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 17:18 GET 68:24 272/2 

CAPCOM eyes too hard because the effect is 

lasting too long. The streaks or the flashes that we're 
looking for are very fast and they do not remain as a scene 
to your eye. And I guess the only thing we could say would 
be to maybe either relax your squint a little bit or to put the 
blindfolds on exceptionally tight. I know this sounds kind 
of screwy, but those are the words that we would like to say 
to you but the actual phenomena we're looking for will be 
a very short lived phenomena it will either be a flash or 
a very fast streak. Something along this — we're not trying 
to load the data, but we feel your describing a different 

SC Bill we lost all that last conservation 

you better repeat it. 

CAPCOM Okay, Gene, sorry about that and here I 

thought I had waxed so eloquently. But the effect you're 
describing is an effect that comes from rubbing your eyes 
or perhaps squinting too hard, but the effect we're looking 
for and I guess we're really not trying to load the data, 
but the effect that we're looking for is a very short lived 
phenomena and would not - 

SC Mark, Ron, I got one in the right eye 

that's coming from going towards - very narrow streak. 

CAPCOM And Gene our only words of wisdom are 

try to relax the eyes a little bit or if you have the blind- 
fold on exceptionally tight you might work on that. But - I 
guess sort of relax and see if we can see the other phenomena. 

S C Ok ay . 


APOLLO 17 MISSION COMMENTARY 12/9/72 17:30 CST 68:36 GET MC273/1 

SC Mark, Ron, one about 12:00 In the right eye and 

looked like it was just a spot. 

SC How about 15 seconds ago? It's so dim 

now I hardly noticed what it was. 

SC Kinda started in the left eye and just 

a flash in the left eye and then a flash in the right eye, 
very dim. Going left, left to right. 

SC Mark. Can't tell if it's right or left 

eye. Looks like it's almost between the two eyes. There's 
a mark in the one of the left eye. It's about right in the 
center. Spot, no streak or anything, just a spot. First 
spot seems to be between the two eyes. Upper half of the 
field of view. 

sc Mark, Gene, straight from the upper right 

eye down to about the middle. 

SC Mark, Ron, about 8:00, (garble) the diameter out 

just a bright flash, it's the brightest flash I've seen yet. Left 
eye . 

sc Just about a second or two after Ron said 

Mark, I saw a vertical bright line in the left side of the 
left eye, just flashed. It was the greatest intensity on the 
last one I had but, the brightness was there but it was kinda 
dull glow to it. It wasn't. A spot that you could really 
focus on. 

SC Mark, Ron, left eye, about 9:30, half 

way . 

sc Mark, Gene, left eye, very bright spot, left 

eye, left side about half way in towards the middle. 

SC That was the brightest one I've seen and 

it was just a spot. 

SC On the intensity of the last one I had 

was, oh, a fourth of the bright one I had before that. Spot, 
yes on the left eye. 

SC Mark about 5 seconds ago, about 6:00 in 

the right eye. Mark, right between the two eyes seemed like. 
Both s pot s . 

SC Mark, Gene, a sharp line from the center 

of the left eye to the upper left hand, upper left hand side. 

SC Mark, Gene it's a very short, very short line 

upper left hand of left eye going towards the right. 

PA0 This is Apollo Control at 68 hours 57 min- 

utes. Apollo 17's distance from Earth is 184 548 nautical 
miles, traveling at a speed of 2488 feet per second. 

sc Mark, Gene, upper right eye, tangential 

to my eye, just a very short line. Moving - 

sc Mark, Ron, oh, a fourth of diameter out 

in the right eye. Light spot seemed like it was coming in. 

APOLLO 17 MISSION COMMENTARY 12/9/72 17:30 CST 68:36 GET MC273/2 

I could see the spot and then the streak, it went from that point 
kind of in, or up, I guess. 

SC Mark, Gene, a dull flash in the bottom in- 

side corner of the right eye. 

SC Mark, Ron. Go ahead, Gene. 

SC Okay. Correction, Gene. That was on 

the left eye, that last one? 

SC The last ones, for Ron, was at 10:00 and 

three-fourth of the diameter out, just a, oh, well it was only 
about an eighth of an inch in diameter, right eye. 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 69:02 CST 17:55 MC274/1 

SC Mark Gene. Mark again, a flash. The 

first flash was in the left eye and the left side. It went 
vertically up and away. And following that was a flash in 
the identically same spot. It was a line flash up and away. 
On the left side of each eye and it went up in both cases, 
but they were split by about 2 seconds. 

SC Mark Ron. One fourth of the diameter out at 

3 o'clock in the right eye. I mean a half a diameter. Half 
a radius, put it that way. 

SC Mark Gene. A flash across the bottom of 

the right eye coming inward from left to right. 

SC On the last one it looked like it was a 

SC Mark Gene, just a spot flash in the bottom of 

the left eye. 

SC This is Ron. My last one there was just 

a spot flash. No direction to it at all. 

SC Ron mark. Mark, this is Ron. When I 

first said the word, it kind of looks like a, almost a sine 
wave transition from the corner and upper at 10 o'clock in 
the right eye to about 2 o'clock in the left eye. Right be- 
tween the two of them. The sine wave with maybe two wiggles 
in it and it was about a fourth of an inch long. Going from 
right to left, yes. And going into the left at about 
2 o ' clock . 

SC Turn that music higher. 

SC Yes. 

SC Mark Ron. Seems like I looked up and as 

I looked up, there was one in the left eye about 12 o'clock, 
just a flash. On the outer periphery. 

PAO This is Apollo Control at 69 hours 

15 minutes. Apollo 17's distance from Earth 184 987 nautical 
miles. Velocity 2477 feet per second. 

SC Mark Ron. Looks to be down about 6:30, 

just a flash. Right eye. Mark Ron. Left eye, about 3:30 
three quarters of the radius out. A very dim flash. About 
3:30. Mark Ron. Left eye. Starting at 5 o'clock on the 
circumference going to 3 o'clock and about thrre quarter diameter, 
three quarter radius, I mean. Just a straight line. Did I say 
left eye? I guess I meant it. Okay, let's see. (garble) 
It appears the motor quit. Okay. 

SC Is that it? 

SC Yes, I'll give it to Gene. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 18:15 GET 69:21 275/1 

SC Okay, you want to take a picture of the 

first one? Okay, stand by 3, 2, 1 mark it, power's on yaw. 
SC Say, Bob or Stu. 

CAPCOM Roger, go ahead. 

SC Okay to add to today. Not last night, 

but I guess the first night I was in bed I definitely saw 
some of these. Because I had a hard time going to bed to 
start with I saw some of the same peripheral horizon type 
things you said were not the type of data you were looking 
for, but I also saw some sets of the streaks and probably 
the one most imposing thing that I remember was - and the 
last one I remember before falling alseep was the fact that 
there was a very bright spot that flashed right between my 
eyes like a very bright headlight like a train coming at you 
only with a flash. It's difficult probably to estimate the 
frequency of any of those because I was in a sort of a sleep 
hazy mode. 

CAPCOM Roger. 

SC But then as today I saw some that flashed 

and lit up the horizon and some that lit up peripherally and 
I guess as you say that's different kind of data, but I did 
see them there and they impressed me. 

CAPCOM Okay, we got all that Gene. 

SC Okay, and it might be interesting to 

know I've never seen it before today. 

CAPCOM Hey, Gene we appreciate all the data we 

were just trying to make the data fit the curve you know the 
old trick. 

SC Okay, I just wanted you to - just tell 

old Mike we saw them that's all. 

SC I will say one thing, though, no ques- 

tion in my mind but that they're there. Last trip I took I 
guess I just wasn't looking for them or paying any attention 
to them. Maybe they were there and I ignored them because 
of other things. But they were there. 

SC Okay, all you flash bugs down there - 

flash bulbs I guess is the word frame 50 I just took four 
pictures to show two on the side and two on the bottom to 
show the position of the ALFMED and one of them of each set 
was focused on the ALFMED the others were focused - the other 
set was focused on the strutts. 

CAPCOM Roger, Jack. 

SC And when you don't have anything else to 

do why don't you have somebody predict where the S-IVB is 
I think I've got her spotted behind us and above us with 
respect to the Earth and our travel from it. 

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 18:15 GET 69:21 275/2 

CAPCOM Item just went out and shot himself, but 

we'll get working on it. 

SC Oh, don't worry about it shoot. I 

thought you guys might have an idea off the cuff there. 

CAPCOM No what's humorous in this Jack is they 

have really been working on that S-IVB impact point. It's 
been a real difficult problem for them so far. 

sc I'll tell you, I bet you Ron could give a st 

sighting on it. I looked at it through the monocular and 
sure looks like the S-IVB. 

CAPCOM Jack, we're not doubting you at all we could 

probably start cranking it right now. 

CAPCOM Jack are you all stowing the ALFMED now 

or are you done? 

SC What's that, Bob? 

CAPCOM Are you all done with the ALFMED now, Ron? 

sc Yes, I've got to get it to, get the plate 

moved back down there yet. 

CAPCOM Okay, Ron. 

SC Get the blindfold off first so I can 

see what I'm doing. 

CAPCOM Roger, I just want you to know we've got 

a real long update coming up to you here on the LOI abort 
charts and it's probably going to be a difficult read up. 
And your the most familiar with the charts you probably 
would want to take them. But whenever you want to take 
them they are on charts on page 3-81, 3-82 and then the cue 
card for LOI limits. Whenever you want to take them it will 
be a lengthy one. 

SC Stand by, Bob let us get squared away 

from the ALFMED then we will get going on that. 

CAPCOM No, I don't want to hurry you, Ron. I 

just want you to get yourself comfortable and be ready to 
take them whenever you want them. It's going to be a lengthy 
time, though. 

SC Okay. Hey Bob, I'm looking at what Jack 

was talking about and it's definitely not a partical that's 
nearby because there is another one I can look at and get a 
three dimensional comparison with. It is a bright object 
and it's obviously rotating because it's flashing. It's way 
out in the distance as I say because there are particles 
that are close by and it's obviously not one of those. It's 
apparently rotating in a very rhythmic fashion because the 
flashes come around almost on time and as we look back at 
the Earth it's up at about 11:00 about - oh, maybe 10 or 
12 Earth diameters I don't know if that does you any good, 
but there is something out there.

CAPCOM Rog, we don't doubt it Gene and we might 

work out a set of fimble angles or something here maybe we 

can get a look at it through the optics. 

SC Okay. And I just want to emphasize that's 

it definitely not one of these particles that tends to look 
like a star out there something physical in the distance.

SC Hey, Robert, what's the final Cowboy score? 

CAPCOM Okay, just an update that the Cowboys won 

it, 34 to 24. And by winning it they wrap up the wild card 
slot in the NFC and so both Washington and Dallas will be in 
the playo f f s . 

SC Sounds good. 

SC Bob, that line of clouds I called a fir 

tree pattern, that swings up towards Hawaii, Hawaii if you 
will, has, also has a mushroom pattern on the top. It has 
the appearance as if two major air masses; one going from west 
to east and the other from east to west have converged along 
that line and the joint movement of air at the interface being 
south to north. And up in the area of Hawaii, I think, it 
tends to mushroom so the pattern then goes back to a flow 
from west to east on the east side and from east to west on 
the west side. 

CAPCOM Roger. 

SC In a little while we'll probably get a 

pretty good look of a - what looks like a very concentrated 
intense storm that I think, is just, just east (garbled)

correct. To be technically correct it should be 2986 at 
that last one. 

SC Okay, I guess we're coming in just a

CAPCOM You'll see from the curves that we 

going to have to update, that you're a lot closer to the 
free return trajectory.

CAP COM Okay, this is the tough one. The first 

thing we're going to do is prod a couple or three points 
here in the Mode 1 2 hour, the Mode 1 2 hour line changes 
also. So you might want to draw a line at a LOI Delta V

APOLLO 17 MISSION COMMENTARY 12/9/72 CST 18:52 GET 69:59 MC279/2 

CAPCOM Roger, Jack. Hey, I've got some information 

on that SIVB that you're looking at. The azimuth was within 
1 degree of what you called when we checked out on your angles. 

CAP COM Hey, Jack. Houston. 

CAPCOM 17, Houston. 

SC Go ahead, Bob. 

CAP COM This was for Jack and Gene. The trench 

has computed the SIVB location in reference to your body axis, 
and the azimuth was within 1 degree, very close, and the -- 
we calculate it should have been out of that window at 62 degrees 
from the X-axis, and you reported 45 degrees, which is just a 
17 degree error is real close there. You know, just eyeballing 
it like that. 

SC That's great. Then, that is the SIVB, huh? 

CAPCOM Okay. Well, we -- you might check it this 

way, Jack. Line up the star Deneb Ola and Rigel. Say again, Regulus, 
I'm sorry, Regulus. Deneb Ola and Regulus, and then, on that line, 
go perpendicular to that line right above Ri — right above 
Regulus, and that should be the SIVB. It forms one point of a 
right triangle with Deneb Ola and Regulus.

SC Go ahead. 

CAPCOM We've got a rather lengthy flight plan 

update series here. We can read up to yon anytime you want. 
Just a reminder that we are sitting here waiting with it. 
Your call. 

SC Generally what is it, Bob. 

CAPCOM It's changing a number of attitudes 

all through the flight plan, 84 32, 84 35, changing VERB 49 
maneuver, things like that due to the TLC change here on 
times and that. 

SC Okay, where are you going to start? 

CAP COM Okay, at that 8432 , standby one. Ah, 

Jack, Flight just told me we can wait on this if you want 
until some other time in the flight plan. We want to get 
into this experiment checklist with the pan camera, mapping 
camera film cycling. Or we can do both of them concurrently. 

SC Hey, Bob, let's get the camera cycling 

out of the way first and then we'll pick up the flight plan 
update . 

CAP COM Roger, we concur with that. 

SC Okay, Bob, I'll get to that camera, just 

a second. The coast of Australia is starting to come into 
view. Still looks pretty clear. Will give you more on that 
later probably. That cyclone I talked about yesterday in the 
vicinity, I believe, of the Solomon Islands, looks even better 
organized than yesterday. It's really tightening up. Starting 
to look very bright and dense right in the core, not to dis- 
similar from Therese. Although, has a little broader extent 
in the southeast quandrant. 

CAP COM Roger. Read that. 

CAPCOM Trying to match that up in my prog here, 

I can't find it. 

SC Well, you didn't have it there yesterday 

either. It certainly looks like a tight little storm now 
though . 

CAPCOM Roger, I understand. 

CAPCOM Jack, would you mind repeating that 

location of that. 

SC Can't give you must on the progress — 

SC Well, I'll try to give it to you a little 

better later. It's the one I was talking about yesterday 
as being in the vicinity of the Solomon Islands. That's 
somewhat east, southeast of New Guinea. 

CAPCOM Yeah. Roger. I've got it. 

SC I think before we go to bed we'll probably 

be able to update the progress of the, that front south of 
Australia also. 

APOLLO 17 MISSION COMMENTARY 12/9/72 19:04 CST 70:10 GET MC280/2

to the east of New Guinea. It's probably right over the 
Solomons. Looks pretty disorganized on our satellite photo. 
From, let's see, I guess that was this morning sometime. 

SC Well, there is a lot of cloudiness in the 

Equatorial regions, Inner-tropical convergence zone in there. 
This is south of that, sort of. I'll talk to you later.

No, not really New Guinea is at the

SC It's getting very tightly wound and the

see if it changes. Okay, Bob just one last thing on that 
line of clouds that stretches up toward Hawaii they look 
very thick and dense based on the structure you can see as 
the terminator approaches them. They cast a pretty strong

CAPCOM Jack, Houston. 

SC Go ahead. 

CAP COM We've been listening to the playback of the 

DSE tape from the ALFMED period, and all three of you sound 
pretty good on that. Gene is still clearer than the rest, but 
all three of you sound real clear and very readable. 

SC Excellent. That'll make up for my note-takin 

CAP COM Roger. 

CAPCOM And, also, Jack. You had a question earlier 

about different response of sea and continental areas when viewed 
through monocular polarizing filter, and I've got a note here 
from John Dietrich that kind of explains it. 

SC Okay, let's hear what John has to say. 

CAP COM Okay. This is pretty much referencing the 

time you were looking at it, and here it is. "Ocean scenes near 
the bright area off Bolivia, which is the specular point, include 
a high proportion of polarized light. The spacecraft, Earth, Sun 
geometry now is approximately equal to the Brewster angle which i 
nearest 53 degrees where maximum plane polarization due to reflec 
tion occurs. Therefore, a high response of scene brightness to 
changes of filter position can be expected. Continental scenes 
are dominated by Lamburgian or diffuse reflectors which are 
characterized by low proportion of polarization in the reflected 
beam. For such scenes, changing position of the polarization 
filter produces changes in scene brightness that are near or 
below the threshhold of de t e ctab il i t y . " Over. 

SC Okay. That sounds very good. It's sort of 

like the contrast between the lunar surface response the oceans 
being more like that, I guess, and between the lunar surface and 
terrestrial land surfaces. 

CAPCOM Roger, Jack. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 19:52 GET 70:59 284/1 

SC That's very good very interesting. Thank 

John for me. I should have thought about that, but I've 
been away from it too long. 

CAPCOM Okay, terminator over Hawaii at 73:45 GET.

PAO This is Apollo control at 71 hours 

2 minutes. Apollo 17's distance from Earth now 187 507 nau- 
tical miles, velocity 2 416 feet per second. On Monday 
80 foreign students who are touring space research science 
centers in the United States will begin a three day visit 
here at the Manned Spacecraft Center. They will observe 
the three periods of lunar exploration by astronauts Cernan 
and Schmitt and will also tour the facilities at MSC. This 
International youth tour began December 2 in Washington D.C. 
and is being conducted under the auspices of the National Aeronau- 
tics and Space Administration with the cooperation of 
the state department. The student group saw the Apollo 17 
launch at Cape Kennedy and since that time have toured the 
Tennessee Valley Authority and the Oakridge National Labora- 
tory facilities in Tennessee. Today they're at the NASA Mar- 
shall Spaceflight Center in Huntsville, Alabama tomorrow 
they will tour the National Oceantic and Atmospheric Admin- 
istration and the National Bureau of Standards in Boulder, 
Colorado. The students were selected by their respective 
governments in response to a NASA invitation, and they range 
in age from 15 to 17 years and rank high academically and have 
strong scientific interests. Following their visit to Houston 
the group will tour the NASA Ames Research Center at Moffitt 
Field, California and the jet propulsion laboratory in 
Pasadena, California. Schedules for the visit here at MSC 
and a complete list of the participating students, and countries 
may be obtained at the MSC news center. At 71 hours 5 minutes 
this is mission control, Houston.

SC very much weather out of it. 

CAPCOM Okay. That, I can't tie up with you 

on that one, Jack, because my prog doesn't go down that 
far. It only stays up in the landing area. And my satellite 
photo doesn't go down that far south either. So, I can't 
touch up with you on that one. 

SC Okay. Well, it looked (garble) stronger yesterday 

and it might develop. Now, there is a larger disturbance 
in the southeastern end of that front. Still south of 
Tasmania, although I suspect unless it stays on a pretty 
northerly course, it will not effect the weather on the 
east coast of Australia very much. 

CAPCOM Roger. Jack, just thought you might 

be interested. I called some friends of yours in Tucson 
and everybody's fine there and wanted to say hello and 
tell you everybody's fine and getting along real good. 

SC Thank you very much. Good to hear. 

They've learned to take care of themselves pretty well, 
h aven ' t th ey . 

CAPCOM They sure have. They're having a 

little trouble with the squawk box, and we'll get working 
on that. They're having trouble reading a little bit, 
but they're keeping up with us. 

SC That's nothing new. But, try to fix 

it please. 

CAP COM Oh, we'll definitely on that one. 

SC Bob, Ron got you the Earth down there 

zeroed in the sextant, and it puts my little binocular 
to shame. I tell you it's a fine instrument. And I'll 
just confirm that the disturbance over the Solomon Islands 
is an awfully tightly wound little storm system, and 
right now, I finally have seen New Zealand for the first 
time in a couple of days for sure. And the South Islands 
got some probably high cirrus over it. North Island looks 
pretty clear. That's the end that I can get right 
n ow . 

CAPCOM Roger. We thought you were looking 

at Regulas, didn't realize you were looking at the 
Earth instead. 

SC Ron's been looking for the booster. 

And he called me down and asked me to look at the Earth. 
He's been holding out on me. 

CAPCOM Roger. 

SC Pass the torch of weather forecasting 

to Ron. 

CAPCOM Hey, Jack. I also have some words 

for you and Gene. Got some advice from the home front 
the thing to do with Ron in the future is to hook up a

CAPCOM Ron, everybody's fine over at El Lago. 

They are doing great- Listening at every word. 

SC Very good, Bob. Thank you very much. 

SC Hey, Bob. We got two of those flashers 

out there. They could be SLA panels. I don't know. They're 
a like in intensity and pretty regular in the intensity 
bright and dim flashes they come out with and they're widely 
separated. One is about the position we called at the first 
time; the other one is, oh, as I'm looking at the Earth, far 
to the left. Closer to the center window now. 

CAPCOM Roger. 

SC Houston, 17. 

CAPCOM Go ahead. 

SC Yah, Bob, what is your analysis chart 

that you haven't, terms analysis chart show for Hawaii today. 
CAPCOM Standby on that. 

CAPCOM Jack, according to the 

SC is that using your chart 

CAPCOM Go ahead on that, Jack. 

SC I was going to say, using your terminator 

time as a partial mark for where Hawaii ought to be, Hawaii ought 
to be, it looks like that cyclonic circulation at the north end of 
the cloud bank I described approaching that area, would be just 
about on the Hawaiian Islands. I'm curious if they're getting 
some weather down there now. 

CAPCOM Standby, right now I've got my weather- 

man right beside me here. 

SC Also that major front we talked about 

last night as being east and south of Japan, it's progressed 
even farther and is, oh, maybe 20 degrees longitude, about 
20 degrees longitude from the Hawaiian Islands and I'm making 
some guesses on exactly where Hawaii is. 

SC Roger, Jack, we've got nothing adverse 

in the Hawaiian area at all. Just a lot of wind, high wind, 
surface wind, surface roughness, but we don't have any bad 
cloud area in the Hawaiian area. I'll get the Hickam 
sequence report here shortly, Jack. 

SC Okay, I don't know, maybe I, our zero 

phase point is now centered just a little south of the 
disturbance near the Solomon Islands, and I see no distinct 
change in the intensity of that zero phase point over 
what I had talked about a couple hours ago. 

SC Roger, Jack. The Solomons Island dis- 

turbance center is confirmed on this chart that I've got. 
It's very definitely confirmed in there. 

SC Okay. Well it's a lot more obvious today than 

yesterday; but even then it was showing a pretty strong 
circulation. It is starting to wrap up. Look very much like 

APOLLO 17 MISSION COMMENTARY 12/9/72 20:30 CST 71:36 GET MC286/2 

Therese did yesterday. 

CAPCOM Roger, I'm sure of that. The one right 

off of Vietnam is also pretty tight, isn't it still. 

SC Well, we can't see that one yet. 


SC Australia generally is still very clear 

except in the northeastern portion where it looks like they 
have got scattered clouds; but it looks like a pretty night - 
over Australia. 

CAP COM Rog. Looks that way from the satellite 

photo from the last couple days. Looks pretty nice down there.

a rain shower or two. But just their standard tropical fluffy

SC Ah, Bob I don't know whether I told you 

or not, but, we ended up with the LMP and the CDR' s suit in 
the bottom of the suit bag. My suit is in the top and I 
sure don't have any idea how in the world the other crews 
got three suits in there. I guess they never did because these 
things are plum full right now, of suits. In the suit bag and 
it's a good thing we lengthened them. I don't have room for 
anything else inside the suit bag. The water bag and, you know, 
the contingency water bag and my G suit and those flight 
things I found a place to stick them all around the wall on 
the outside of the suit thing.

Sc Bob, you made some comment earlier about 

the weather it may have been Hawaii, but you broke up. 

CAPCOM Roger I just got the sequence report for 

Hawaii. Hickam had 35 hundred scattered 45 hundred broken 
with minor rain showers and Hilo had about the same and basi- 
cally it's just their tropical pumpy weather out there. Ty- 
pical - nothing no frontal type weather or no cyclonic type 
weather. J * 

. U SC . , 0kay > wel1 ic ma y b e just patterns induced 

by the wind currents or maybe I don't have the position of 
Hawaii quite right. 

CAP COM Well, it's possible they do have high 

winds out there and I've seen it just flying in that area 
in the past where those broken clouds get pretty close toge- 
ther at times it almost looks like a solid overcast. And 
especially when you look at it from an angle they all blend 

SC 1 b °P e y° u r going to save all those charts 

your gathering together as we talk about it on this outbound 
leg. Be interesting to compare them and the pictures we take 
sometime in January. 

CAPCOM Jack the weather just was out here and 

they told me that's exactly what their doing and if your time 
will permit in January they'd like to go through and maybe 
help piece them all together. But, they're going through these 
transcripts and they're gathering all their satellite pictures 
plotting what your seeing versus the satellite pictures 
etc. etc. and they'd like to go over it with you when you 
get back. J 

, SC x ' d love to do that. I hope in general 

we re getting the directions right at least I know I'm going to worry 
about the description and it's hard to place points on the globe 
particularly in the Pacific if you can't identify land masses near 
them or have those nice little latitude and longitude lines 
painted on the Earth.

Apollo 17 now 189 16 7 nautical miles from Earth, traveling at a 
speed of 2377 feet per second. And, we're just over an hour 
away from the time that Apollo 17 will enter the lunar sphere 
of influence. Flight Dynamics Officer, Bill Boone, has recom- 
puted the time for that event. That will occur at 73 hours 17 min- 
utes 45 seconds. 

SC Houston, 17. 

CAP COM Go ahead, 17. 

SC Yeah, I -- may have misled you earlier about 

a storm system south of Tasmania. Its -- if there is one, it's 
just developing, and it's probably 20 degrees longitude south. 
As I recall yesterday, there was some indication that a couple 
fronts were joining forces and moving in that direction. 
Today, the weaker and more western front appears to have domi- 
nated the system, and the only area where there seems to be 
cyclonic circulation developing is that point way south of 
Tasmania. That conceivably might move up and affect New Zealand 
in a few, in a couple days, but right now I don't see how it could 
affect Australia.

Apollo 17 has just entered the lunar sphere 
and the distance velocity displayed here in the 
now referenced to the Moon, Apollo 17 
miles from the Moon, traveling at a speed 

of 3355 feet per second. 


APOLLO 17 MISSION COMMENTARY 12/9/72 CST 22:14 GET 73:20 291/1 

PAO This is Apollo control at 73 hours 

23 minutes. On it's present trajectory and without doing a 
lunar orbit insertion burn Apollo 17 would reach it closest 
approach to the Moon at a ground elapsed time of 88 hours 
58 minutes 12 seconds. The distance of that closest approach 
would be 53.48 nautical miles and spacecraft velocity at 
that time would be 8 198 feet per second. We expect the 
crew to settle down into an 8 hour rest period here very 
shortly. On the flight plan that rest period due to begin 
at 73 hours some 24 minutes ago. We do expect that the crew 
will shortly go into that rest period. 

SC Hello, Houston. 

CAPCOM 17, Houston, go ahead. 

SC Okay, Bob we're going to turn out the 

lights now and hit the sack. 

CAPCOM Okay, have you gone through the presleep 

checklist getting ready on the comm and all that? 

SC Yes, that's affirm. The presleep check- 

list. Am I wh at ? 

CAPCOM We're not getting any biomed data on - 

suppose to be on Ron I guess. (garble) 

SC Houston, do you read 17? 

CAPCOM 17, Houston, how do you read me? 

SC Yes, I'm reading you Bob what did you 

say. Am I what? 

CAP COM Might check the sensors on Ron. We're 

not getting any biomed data. Is he unplugged? 

SC Well that's because he's - yes, he's 

unplugged give him a chance to get hooked up and change some 
leads here . 

CAP COM Okay. 

SC Everything else the presleep check, pre- 

sleep checklist is complete. I'm going to leave the comm cap 
on tonight. Our tone boost doesn't work so I will just be on 
comm all night. 

SC Do you have any biomed on, Ron? 

CAP COM Stand by on that, Gene. 


APOLLO 17 MISSION COMMENTARY 12/9/72 22:40 CST 73:47 GET MC292/1 

SC Goodnight, Robert. 

CAPCOM Goodnight, Gene. 

CAPCOM Got a busy day tomorrow and we'll be 

with you. 

PAO This is Apollo Control at 73 hours 

49 minutes. We said goodnight to the crew at 73 hours 
and 47 minutes and we don't expect any more conversation 
with them tonight. Flight Surgeon is now receiving good 
biomedical data from the Command Module Pilot, Ron Evans. 
We'll leave the line up for a few minutes in case there 
are any postscripts to the air-ground and if not we'll take 
the line down and come back up hourly with reports. But 
for the moment we'll leave the line up live. This is 
Apollo Control. As the crew turns in the spacecraft is 
32 741 nautical miles from the Moon, velocity 3362 feet per 
s e cond. 

PAO This is Apollo Control at 74 hours 

4 minutes. Apollo 17 now 32 264 nautical miles from the 
Moon, velocity 3366. The crew has settled down for the night 
and we'll take the lines down now and come back up with hourly 
reports . 


APOLLO 17 MISSION COMMENTARY 12/9/72 GET 74:50 CST 2343 MC 293/1 

PAO This is Apollo Control at 74 hours 50 minutes. 

Gene Kranz and the white team of flight controllers are prepar- 
ing to take over duties in the Mission Control Center, relieving 
the orange team which has been directed tonight by Chuck Lewis. 
This has been a relatively quiet shift. A major activity was 
the medical experiment to gather more information on light 
flashes that most Apollo crews have seen with their eyes closed. 
We also updated the ground elapsed time clock during this shift, 
moving it ahead 2 hours and 40 minutes, this being necessary to 
bring the Greenwich mean time ground elapsed time in the flight 
plan into agreement. These areas had not agreed because of the 
late launch. The crew reported seeing the S-IVB in the distance 
at one time during the shift. The spacecraft entered the lunar 
sphere of influence at 73 hours 17 minutes 45 seconds, and we 
said goodnight to the crew at 73 hours 47 minutes. 6 hours 
8 minutes remaining In this rest period now. There will be no 
change of shift news conference when the shift breaks at mid- 
night - no change of shift news conference. In its present 
time, Apollo 17 is 30 705 nautical miles from the Moon, velocity 
3 378 feet per second. At 74 hours 52 minutes this is Mission 
Control Houston. 


APOLLO 17 MISSION COMMENTARY 12/7/72 GET 75:37 CST 0030 MC 294/1 

PAO This is Apollo Control at 75 hours 37 minutes. 

Flight director Gene Kranz and the oncoming white team of flight 
controllers have been going over the status of the mission and 
find everything progressing very smoothly at this point. There 
are no anomalies in the performance of the spacecraft. All 
systems in very good shape and we're either up to or slightly 
ahead of the flight plan values on consumables at this point. 
During the shift a number of the flight controllers will begin 
working on some of the data the crew will use on awakening to 
place the spacecraft in lunar orbit, that event scheduled to occur 
at about 88 hours 56 minutes, and the retrofire officer 
and the flight dynamics officer will be busy during this shift 
working out some of the preliminary numbers that'll be used in 
the lunar orbit insertion maneuver. There is still no decision 
as to whether or not midcourse correction 4 will need to be per- 
formed and we suspect that that decision will also be made 
later on during this shift. At the present time Apollo 17 is 
29 152 nautical miles from the Moon and the spacecraft velocity 
is now 3 391 feet per second. This is Apollo Control Houston. 


APOLLO 17 MISSION COMMENTARY 12/10/72 01:30 CST 76 :37 GET MC 295/1 

PAO This is Apollo control at 76 hours 37 minutes. Now 

about 4 - 1/2 hours away from the scheduled crew awakening time, the 
flight surgeon reports that the crew appears to be resting comfortably 
at this time. Command Module Pilot Ron Evans is wearing the biomedical 
harness during this sleep period. And Commander Gene Cernan has 
the watch wearing the headset that would receive any call from the 
control center. Apollo 17 is 27 178 nautical miles from the Moon. 
And we're watching the velocity gradually build up under the growing 
affect of lunar gravity, up now to 3411 feet per second. This is 
Apollo control Houston standing by at 76 hours 38 minutes. 


APOLLO 17 MISSION COMMENTARY 12/10/72 0230 CS T 7737 GET MC 296/1 

PAO This is Apollo Control at 77 hours 

37 minutes, continuing to maintain the watch while the crew 
aboard Apollo 17 gets some sleep - Now about 3 1/2 hours 
left in that sleep period and that could be extended by 
30 minutes or so if a decision is made not to make the final 
midcourse correction before going into lunar orbit. We 
expect to be getting a reading on the necessity for that 
midcourse correction which in any event will be a very 
small maneuver, before this shift ends. The midcourse 
correction opportunity occurs at 83 hours 55 minutes in 
the flight plan and the Flight Dynamics officer has gotten 
what appears to be a good final indication of the impact 
coordinates for the Saturn third stage. The latest coordi- 
nates are 4 degrees 11 minutes south and 12 degrees and 
23 minutes west. Apollo 17 at this time - 25 131 nautical 
miles from the Moon. The spacecraft velocity 3434 feet 
per second. This is Apollo Control at 77 hours 38 minutes 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 03:30 GET 78:37 MC 297/1 

PAO This Is Apollo Control at 78 hours 

37 minutes. There's been no change in the spacecraft 
status during the past hour. Everything continues to 
function normally and we have about two and one half 
hours remaining in the crew's sleep period. The flight 
dynamics officer reports that we've got a midcourse 
correction if it's performed prior to Lunar Orbit Insertion 
of about one half foot per second or less and that very 
small maneauver, if performed, would occur at 83 hours 55 
minutes. Apollo 17 is now 23 112 nautical miles from 
the Moon and the spacecraft velocity up to 3 460 feet 
per second. We'll see that increase to somewhat in excess 
of 80 000 feet per second as the spacecraft reaches the 
Moon and swings around the Moon goes into orbit. The 
Lunar Orbit Insertion Burn removes on the order of 3 000 
feet per second from that velocity. A lunar orbital 
velocity of about 1 mile per second. The flight surgeon 
has noted some stirrings of a bit of an elevation in the 
heart rate of Ron Evans, who is wearing the bio-medical 
sensors during this sleep period, although for the most 
part Evans has been sleeping soundly. At 78 hours 39 
minutes, this Apollo Control, Houston. 



MISSION COMMENTARY 12/10/72 CST 0430 GET 79:37 MC 298/1 

PAO This is Apollo control at 79 hours 37 minutes. 

Now about an hour and /2 away from the scheduled time for crew 
awakening. And it has again been very uneventful, very quiet sleep 
shift. With the flight controllers here in mission control monitoring 
spacecraft systems. Everything continuing to perform almost perfectly 
as planned; everything nominal. And our flight dynamics display at 
the present time is showing the spacecraft distance related to 
Earth, Apollo 17 now 198 800 nautical miles from Earth, traveling at 
a speed again with respect to Earth of 2168 feet per second. After 
awakening the crew's major activities during the day include jettisoning 
the scientific instrument module door which exposes the scientific 
instruments in the spacecraft's service module to the lunar environment. 
Lunar orbit insertion is scheduled to occur at about 88 hours 56 minutes. 
The Saturn third stage will be impacting the lunar surface. And there's 
still a possibility of a final midcourse correction prior to lunar 
orbit insertion. That midcourse correction to occur - if it occurs 
at 83 hours 55 minutes. And we expect that we will have a decision 
or recommendation from the flight dynamics officer within the next 
couple of hours as to whether or not that midcourse correction 
will be required. If it is done, it will be a very small maneuver 
performed with the reaction control system thrusters on the CSM. 
At 79 hours 39 minutes this is Apollo control Houston. 


APOLLO 17 MISSION COMMENTARY 12/10/72 0534 CST 8041 GET MC 299/1 

This is Apollo Control at 80 hours 41 minutes. We have 
about 18 minutes remaining before the scheduled crew awakening 
time, however, we're planning to give them at least an additional 
15 minutes of sleep and perhaps 30 minutes additional. The 
Flight Dynamics officer hopes to delay a decision on the need 
for midcourse correction 4 until additional tracking data is 
available. That maneuver, if its performed, remains very 
small - on the order of a half foot per second. And the de- 
cision revolves around what height of approach pericynthion 
we'll have with or without the maneuver. Tracking data right 
now shows that Apollo 17 will be approaching the Moon with a 
pericynthion of about 52 nautical miles - the desired peri- 
cynthion is 53 1/2. And the FIDO would like to get a bit 
more tracking data before making that decision. So we'll be 
putting off the decision as to whether or not to awaken the 
crew or give them more sleep time until the last possible 
moment. Apollo 17 at this time is 18 839 nautical miles from 
the Moon and the velocity up to 3500 feet per second. We've 
seen no signs of activity aboard the spacecraft. The Flight 
Surgeon will begin to note increased heart and respiration 
rates on Ron Evans, who is wearing the bio-medical sensors 
during the sleep period and before receiving a call from the 
crew we'll see the voice sub-carrier come on and we'll be 
watching for any of those cues. If it appears that the crew 
is indeed up and about we'll bring the lines up and standby 
live or as soon as the decision is made to send them a wake- 
up call we'll come up and standby live. At 80 hours 44 minutes 
this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/10/72 GET 81:25 CST 0618 MC 300/1 

p A0 This is Apollo Control at 81 hours 25 minutes. 

We are planning to put a call through to the crew in about 
5 minutes to awaken them and Apollo 17, at this time, is about 
17 350 nautical miles from the Moon. Spacecraft velocity is 
about 3567 feet per second. After awakening the crew we will be 
discussing a minor problem that has been noted during the sleep 
period. This involves a heater cycling in one of the three 
cryogenic hydrogen tanks that supplies hydrogen to the fuel 
cells. The nature of the problem is a heater that is cycling 
more often than normal. These heaters are controlled by a 
pressure-sensitive switch on the tank as the temperature within 
the tank drops and the pressure drops. The switch senses this 
and activates the heater to bring up the temperature and hence 
the pressure within the tank and ensure a constant flow of 
hydrogen to the fuel cells. The sensor appears to be responding 
to a much narrower range of temperature decrease that would 
normally respond to about a 20 degree excursion in temperature 
and it is now apparently responding to about a 2 to 3 degree 
temperature excursion, and therefore cycling more rapidly than 
would normally be the' case. This in itself is of no concern, 
however if the automatic cycling should fail, if the automatic 
cycling function should fail, it would require going to a 
backup manual mode whereby the crew would be instructed to 
turn the heaters on and off at certain intervals to maintain the 
proper pressure in the tank, which, by the way, is a mode of 
operation that has been used on previous missions, and works 
very well with a minimum impact to the crew time. And, as 
mentioned at this point we would see no reason for having to go 
to a manual mode. That would require some subsequent failure. 
This situation, however, will be discussed with the crew and 
they'll be advised as to the procedure that would be taken in 
the event that subsequent failure should occur necessitating 
the manual activation of the heater within this one tank. And 
we are now about 1 minute 50 seconds away from the scheduled 
awakening time, having given the crew an additional 30 minutes 
of sleep. The flight dynamics officer expects to give us a GO 
or NO/GO for the midcourse correction prior to lunar orbit in- 
sertion in about a half an hour at some 82 hours ground elapsed 
time. We'll continue to stand by live for that call to the 
crew . 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 06:23 GET 81:31 MC 301/1

SC Good morning Houston, anybody there? 

CAPCOM Okay, good morning, it's LOI day, 

Ap o 1 1 o 1 7 . 

SC Hello, Robert, you gave us an extra 

half hour. 

CAPCOM That's affirmative. We're presently 

still debating on midcourse 4, Geno, and at the present 
time it's small, about a half a foot per second, we're 
expecting a final decision on whether it's necessary or 
not in approximately 1 hour at 82:30. We'll let you 
know then, but it will be small and so we decided to 
give you an extra half hour of sleep. 

SC Okay, Bob, without me having to 

look it up when will it come if it comes. 

CAP COM Standby. 83: 55 , so we'll give you 

about an hour and 25 minutes advance notice. 

SC Okay. Well, we'll start stiring 


CAPCOM Okay, give me a call when you want 

to talk to people. 

SC Hello, Houston. 

CAPCOM Hello there, 17, good morning. 

SC I'm not sure we're ready to talk yet, 

Bob, but I just thought you'd like to know we got a pretty 
spectacular view of Africa today. We can see the Sinai, 
can see the Red Sea, the Sea of Aden and for the first time 
I think we cannot only see the Mediterranean, but we can see 
the most of the Southern European countries, Turkey and 
Greece and up in Italy and some of those places, can't 
quite see Spain because you're just about on the horizon 
and for the most part, it looks like the weather throughout the 
Mediterranean and Northern Africa looks pretty good. 

CAPCOM Okay, we're copying that. And if you 

guys are willing to do a little switch flipping this early in 
the morning, we'd like you to turn on the pan camera heaters, 
which means if somebody's down there in that vecinity it's 
SMAC power ON and the self test switch to heaters. Over. 

SC You want the SMAC power ON and the 

self test switch to heaters. 

CAPCOM That's affirm. 

SC Okay, we'll get that. 


SC Okay, we got both of those.

Ready to copy. 

Okay. It was a big day yesterday eating-wise. 
CDR had sausage patties, pears and cocoa for breakfast. Ham, 
a quarter, 1-quart cheese-spread. 1/2 bread and 1/2 cereal bar, 1 oran 
beverage for lunch, tomato soup, half a hamburger, half mustard, 
vanilla pudding and an orange pineapple drink for dinner. 

Okay, copy that. 

Five hours of good sleep, and two more containers 

I got the CDR' s food and then you broke 
and two containers of water. Was

SC Okay Houston, 17, how do you read now? 

CAPCOM Okay read you again, go ahead. 

SC Okay for the LMP the food eaten - well let's 

see, I guess its a toss-up eaten vs. not eaten. I'll give you 
what I ate, sausage patties, grits^ pears, pineapple-grapefruit 
drink, coffee and let me make a note that the package of peaches 
in that pack was broken in the package. Also, I had chicken 
soup, ham, bread, orange drink and 4 bacon squares. For dinner 
I sort of ate some left overs and grape drink, corn chowder, 
chocolate pudding. And I had - stand by. The PRD reading: 24080, 
and 7 1/2 hours of very good sleep last night. I took a Seconal 
in order to get to sleep and I've had 1 and 1 or 2 and 1/2 con- 
tainers of water since last report. 

CAP COM Okay copy all that, Jack. 

SC Okay, the CMP. The chow hound of the kennel 

here had: sausage, grits, fruit cocktail orange beverage and 
coffee. He had ham, cheese bread, peaches, cereal bar and 
orange-pineapple drink. Later on he had tomato/ soup y half of a 
hamburger, half mustard, vanilla pudding, sugar cookies, grape 
drink and tea. And he has a complaint this morning much like 
mine that his apricot package had broken in the bag, and al- 
though not too severe itself, it makes everything else pretty 
s t icky . 

CAP COM I copy that. 

SC Okay, CMP medical is 15031 PRD, he had 

7 hours restless sleep and he'd like a few comments from the 
doctors on how that looked on his biomed and he had a Seconal 
and he had 4 containers of water. 

CAPCOM Okay, we copy all that one also, Jack, you 

guys still gonna fit in your space suits? 

SC If you'd stick around, we tried those on 


CAPCOM Roger copy, tried to talk to you guys 

yesterday morning but I didn't quite make it, there was a 
problem apparently some place. 

SC That's all right, we're stuffing him with 

food so he can't sleep. 

CAPCOM Okay and the comment concerning Ron's sleep 

from the surgeon, Jack is that he was restless the first hour 
and had periods of restlessness during the night but we logged 
him for about 7 hours of sleep also. But we did see periods 
of wakefulness, some of which were up to 10 minutes long. 

SC That sounds about right, that's good, thank 

you. If I can't tell how long I'm awake and you know, how long 
you were really a sleep. 

CAPCOM I'll tell you, Ron, you wake up during the 

night you might sit there and stare at the second hand and then 
count how long you're awake. 

SC (Laughter) okay. 

CAPCOM Okay, we owe you guys a consumable update. 

And on RCS consumables you're RCS fuel remaining is still 1.4 per- 
cent above the Flight Plan, that's a slight improvement over the 
1.3 percent from yesterday. 

APOLLO 17 MISSION COMMENTARY 12/10/72 06:59 CST 82:05 GET MC- 303/2 

SC I guess everything else is about like yes- 

terday, is that right, Bob? 

CAP COM Roger, consumables are still about the same. 

If you guys will wind your watches we'll consider the post- 
sleep checklist finished. 

SC Okay and Geno has got his no bias check 

for you. 

CAPCOM Okay, roger on that, we're waiting. 

SC Okay, Bob, made 2 checks over a period of 

100 seconds. One was minus 99.0 and the other was minus 98.9, 

CAPCOM Okay we copy minus 99.0 and minus 98.9, Geno. 

SC And - 

CAPCOM And we'd like omni Charlie, please there, 17. 

CAPCOM And Apollo 17, Houston, we'd like to recommend 

you go squelch off at this time if you haven't and we'll keep 
calling the omni as it changes you're to rotate, over. 

SC Bob, we've been flying normally with it in 

able, maybe you think that's the problem? 

CAPCOM Stand by a minute and while we're thinking 

about, can we confirm that the only medication you've had is a 
Seconal for you and a Seconal for Ron, and nothing for the commander? 

SC This is Geno, that's right, I did not take 

any Seconal, last night. One thing I wanted to talk to you about 
though, I took one anti-gas pill after breakfast, I took one 
after supper and I took one prior to going to sleep which were 
probably within an hour apart. If you've got a better solution 
than those gas pills, I'd sure like to hear it. 

CAPCOM Understand that Gene, we'll get back with you 

on that later. 

CAPCOM And, Jack, as far as turning the squelch off, 

they do believe that we're better with that for margins in gen- 
eral managment than this distance with the omni. As soon as we 
plot a PTC and go on the high-gain we'll be much better off. 

SC Okay, Bob. 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 07:12 GET 82:18 MC- 304/1 

CAPCOM And, 17, Houston. You can do without your water 

dump now. We're in good shape. We'll dump at 94 hours. 

SC 94 hours. Okay. 

SC Bob, does that mean we can go ahead with the 

urine dump on schedule? 

CAPCOM Say again there, Geno, on the urine dump. 

CAPCOM Say again, Geno, on the urine dump. 

SC Rog. Can we press on with it on schedule? 

CAPCOM That's affirmative, sir. It's just that we don't 

need to do the water dump, that's all. 

SC Oh. 

S C Okay , fine . 

SC Okay, that was 72 30. 

CAPCOM Okay. Copy that. And part of the reason we 

had a little problem that this last time, Jack, was we planned 
to call the OMNI's and we didn't get the word around down here. And 
we didn't call the OMNI to you in time. We're still planning on 
doing that, and I think we'll be more coordinated next time. 

SC Okay. We'll bear with you. 

CAPCOM And Jack, I presume that's magazine November, 


SC That's affirm, Bob. 


APOLLO 17 MISSION COMMENTARY 12/10/72 07:21 CST 82:28 GET MC305/1 

CAPCOM Omni, Charlie, 17 please. 

S C Got it . 

CAPCOM And Apollo 17, Houston, for your Information 

we are scrubbing midcourse 4 and you can stay in PTC until 
83:30 which will be about when you start to get ready for LOI 
anyway. We'll give you a call on that. 

PAO This is Apollo Control. Apollo 17 now 

14 thousand 948 nautical miles from the Moon and CAPCOM, Bob 
Parker, just advising the crew that we will not require a 
midcourse correction prior to lunar orbit insertion. The 
flight dynamics officer had been reviewing tracking data and 
establishing another vector, as he calls it, on the trajectory 
based on that last vector and it appeared that a midcourse 
correction of something less than a half of foot per second 
would be required, if performed. And flight director, Gene 
Kranz, made the decision to cancel the midcourse correction 
prior to lunar orbit insertion. 

SC We're about three quarters of the way 

through eating. You got some news for us? 

CAP COM Stand by, I'll see. Did you catch the 

midcourse 4 scrub? 

SC Yes sir. Apparently, you're not getting 

some of our acknowledgements. 

CAPCOM Okay, must be. Captain Young, here, wants 

to tell you that it's raining outside and the paper boy 
apparently hasn't come in yet. Omni Delta, please. 

SC I'm surprised he didn't get his paper 

delivered before he came in. 

CAPCOM Roger. I suppose I should apologize 

to all the paper boys after saying that. But the news is 
still being put together for you guys. And standby. And 
Geno, some advice to you on the gas pills. I guess - 
suggestion down here from the surgeon is that one thing we 
ought to be sure to do is to chew the pills thoroughly. And 
apparently it helps in their effectiveness quite a bit and 
Dr. Young, beside me, also suggested if you're chewing chewing 
gum you might cut down on that a bit because he thinks this 
might be causing some gas. 

SC Thank you. 

SC I might add that both of those alternatives 

have been worked on. 

CAPCOM We thought probably so. 

SC Bob, although that we're getting close to 

concentrating our attention on the Moon, it doesn't decrease 
the interest in looking back at the patterns of activity we 
can see on the Earth. That storm - 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 7:31 GET 82:38 306/1 

SC Spatters of activity we can see on the 

earth. That storm I talked about yesterday, that was in 
North Africa, looks like it has left that area and has moved 
in - maybe, if it's there at all, it's just over the Iberian 
Peninsula, and maybe Gibraltar and that area is getting a 
little activity today. 

CAPCOM Okay, copyright that. 

SC It does not look very well organized, 

but - it's not very well organized right now, but - it's 
right out on the LM and it's hard to get a good view of it. 


SC The storm I guessed yesterday, I thought mi gh 

be moving into the Cape of Good Hope, looks like it's disipating 
and also staying south of that area. The whole of Africa is 
essentially clear except in the southern part of the inter- 
tropical convergence area where there's scattered patches of 
fairly dense clouds, probably getting scattered rain showers 
of some kind in there this morning. Some of those extend 
farther south then I've - we've seen them - down into South 
Africa. There's a - on one of the earlier REV's, when I 
looked out of the terminators, it looked like there was a 
depression developing about 30 degrees longitude east of 
Madagascar in the middle of the Indian ocean. A little bit 
northeast of Madagascar there's also a new area of clouds 
developed that looks like it's getting organized into a cyclo 
p a 1 1 e rn , 

CAPCOM Roger. Turn OMNI alpha, please. 

SC Okay, you got it? 

CAP COM Thank you. 

CAPCOM Okay, and Jack, while you guys are finish- 

ing your lunch - your breakfast there, excuse me. Are you 
all on your headsets? 

SC Yes sir. 

CAP COM Okay, let me brief you on a little funny 

that we saw last night, and I'll start the briefing by mention- 
ing that at the present time, it is not a great concern, but 
just to keep you up to date with what's going on, let me 
mention it to you. About 70 hours, which was probably about 
the time of your last exercise period, we saw 3 funnies with 
the hydrogen tanks, as I say, none of which is causing any 
great concern. The first of these was a shift to the limits 
of the pressure switch, the ones that turns the heaters on 
and off, remember there are two of those switches, one on 
tank 1 and one on tank 2 and they work in series, and one of 
those switches, we can't tell which, but we suspect it's 
probably tank 2 because of the other funnies, I'll get to in 
a minute in tank 2. One of those switches went from a 13 psi 
range, in other words a plus or minus 6.5 psi range. It 
changed its range down to plus or minus 1.5 psi so its now 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 7:31 GET 82:38 306/2 

CAPCOM total range is only 3 psi. The main 

result of that is that it means that the pressure switches 
and the motor switch turning the heater on, acts more fre- 
quently or a shorter period of time. The second thing which 
we observed following this, and we're not at all sure if there 
is any correlation between this and the others. We observed 
a high frequency pressure oscillation in tank 2. It was about 
a 5 psi peak to peak oscillation, a frequency of about 2 
cycles per second. And this lasted for about 3 to 5 minutes. 
A third funny that we observed, this was in tank 2. The 
third funny that we observed was an erratic, and possibly 
correlated with the high frequency oscillation, but an 
erratic total fuel cell occurrance, and here again we were 
looking at oh, peak to peak variations of something like 
5 amps or of 5 to 10 amps. And the suspicion is that coupled 
with the shift in the limits of the pressure switch, some 
acoustic vibrations were set up in that tank, and we may have 
seen them causing the oscillation of the motor switch, 
which was then reflected in the fuel cell currents. Again 
these erratic, and possibly correlated fuel cell currents 
lasted for about 3 to 5 minutes. And since then, all during 
the night, ther've been no further events of this sort and 
the pressure switch with its reduced limits has been acting 
quite normally, just with the reduced limits overnight. As 
I say again, we're looking at it, people are studying it in 
great detail, with no real answer at the moment, but there 
is no great concern at the present. And it appears that the 
worst that can happen is for the motor switch to stall be- 
cause of over use. And if this would happen, it would force 
us to go to manual management of the heaters on the H2 tank. 
That appears to be the worst, at the moment, that we can 
anticipate from this group of funnies. Over. 

SC Okay, Bob. Understand that. You know, 

I wonder if we ought to stop stirring the cryos the way 
we've been doing it. 

CAPCOM That has been suggested, but again, it's 

not very clear that any of these things are terribly correlated. 

SC Okay, also, you know, if you want to 

reduce the activity on that switch, depending on how much 
you need to have it done during quiet periods such as eat period 
and things like that, we could go to manual operation. 

CAPCOM Negative, Jack, because the switch - 

OMNI bravo, please, 17. 

S C Ok ay . 

CAPCOM If you pull out your schematics there, you'll 

find that no matter what you do, the - you can turn the 
thing off, in fact, and the switch will continue to operate 
the motor switch, the pressure switch will continue to operate 
the motor switch off the service module busses. There's 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 7:31 GET 82:38 306/3 

CAPCOM Nothing you can do. The only thing you'll 

do if you go from AUTO to MANUAL or OFF is you'll keep the 
currents from going to the heaters, but the motor switch 
will still operate. 

SC Okay. Thank you for the education. 

CAPCOM And I've been corrected, the frequency 

of the pressure oscillation was more in the vicinity of a 
cycle every 4 or 5 seconds. 

SC Okay. 

CAP COM And 7 - 

SC Let me ask a couple questions. 

CAPCOM Go ahead. 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 07:40 GET 82:47 MC-307/1 

SC Make sure I understand this. You're not sure 

whether the heater cycling and the pressure cycling were correlated, 
is that correct? 

CAPCOM That's affirmative. 

SC In a cycle every four or five seconds, is it 

possible for the heaters to effect the tank that fast? 

CAP COM That's not possible, so the only thing really - 

we think could - the tank is too much of a heat sink to do it that 
way. What may have happened was that if you set up an oscillation, 
a mechanical oscillation in the tank to one way or another, that 
this could then have active back-up on the motor. But the motor 
switch in driving the heaters could not have reinforced the oscilla- 
tion because the tank is to much of a heat-sink. 

sc Okay. When did you say this happened with respect 

to our exercise period? 

CAP COM That's not well pinned down 17. We do know it 

occurred since about 71 hours and it did occur at approximately 
70 hours which was about the time of your exercise period. But, we 
haven't been able to correlate that exactly with the start or the 
finish of the exercise period. 

sc Well you know you should be able to do that 

because of the biomed on the - at least on me and Ron's was on too. 
But, as soon as I started exercising he you should have the BIO MED 
data on my heart-rate. It was unscheduled exercise period, we just 
went into it before eat period, I think. Let me check back. 

CAPCOM Okay. And, we can check back and time you more 

specific on what the times were there in terms of your exercise 
period also. I'd like OMNI Charlie, please, there 17. And we might 
mention that oscillations like had been seen on the ground under 
somewhat different circumstances, but oscillations like this have 
been seen on the ground in ground tests previously. And I might say, 
also, that as far as other things in the spacecraft are current 
everything looks absolutely normal, nominal, as the case may be in 
great shape and I might emphasize again, that we've seen none of 
this oscillation again since 71 hours. Over. 

sc Okay. Bob. That was, as you say, pretty close 

to the exercise. I can't pin it down in the checklist exactly but 
it was somewhere after ALFMED was complete. And before we changed that 
canister, I think we changed that canister a little early. About 
70:50. So I think the manning should have pretty good data on when 
we were exercising. And the reason I say that, because the way we 
were, I was exercising anyway, I'm sort of running in place against 
the LEB and conceivably could have gotten oscillation going in the 
tank . 

CAPCOM Roger. Understand that. 


CAP COM And 17, we did a little investigation of times 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 07:40 GET 82:47 MC- 307/2 

CAPCOM down here. We found that at 71:12 you were 

exercising at 130 beats per minute there, Jack. And we think 
the exercise period ended about 10 minutes later on 71:22. The 
H2 tank funny started about 71:37 with the pressure switch shift 
and 71:42 with the oscillations. Over. 

CAPCOM So then it would be 15 minutes after the 

exercise period was over. 

SC Okay. I just wanted to clear my reputation, 

Bob . 

SC Now, it's perfectly clean again. 

CAPCOM As clean as ever anyway. 

CAPCOM Okay. 17 I guess we decided to let - we'll 

run the OMNIs down here instead of having you guys push them all 
the time. So if you'll select OMNI BRAVO at the present time, 
then we'll take over and run these OMNIs for you. 

SC Okay Bob. It's not too big a deal. If any- 

time you think you want to talk to us continuously go ahead and 
call them, if we're not busy. 

CAPCOM Okay. Copy that. Let us know when you're 

ready. I've got a pad here for you guys to copy, but there's no 
big hurry on it. Finish your eat period and give us a call. 

SC Okay. I'll be with you in about 5 minutes. 

CAPCOM Say again there, 17. 

SC Be right with yoxi, Bob. 

CAP COM All right. 

SC And looking at the Flight Plan, we're going 

to go ahead and change the canister and we've got the H2 pressure 
line heaters on. We're going to configure for the urine dump. 
We'll go ahead and do our stop our PTC at 83:30 and then we'll do 
our P52 . 

CAPCOM Roger. Copy that. 


APOLLO 17 MISSION COMMENTARY 12/10/72 07:50 CST 82:57 GET MC308/1 

CAPCOM And 17, that P52 at 83:10 was primarily 

intended for the MCC-4. There's some more following anyway 
before LOI so we suggest you scrub the P52 at 83:10. 

SC Okay, fine. I may just do a little 

OJT without torquing. 


57 minutes. We're 
in Mission Control, 
by flight director, 
the Gene Kranz team. The 
shift is Astronaut Gordon 

That's your business. 
This is Apollo control at 82 hours 
completing a shift handover at this time 
The team of flight controllers headed 
Gerry Griffin, coming on now to replace 

spacecraft communicator on the upcoming 
Fullerton. We do not plan to have 

press briefing at this shift change. 

Bob, when we come out of PTC, then you 
right to the SIM door jett attitude. 
That's affirmative, 17. 

Okay, and you want us to do that about 
Roger. That's affirm. 

Okay. Bob, what pad are you going to

Yeah, I'm just about ready, Bob. 

Okay, give me a call when you get it. 

And while you're getting ready there 
back to yesterday afternoon just after the 
and the question that's raised is whether 

you were running the DAC or some other miscellaneous equipment 
at that time which might have caused some high current usage? 

APOLLO 17 MISSION COMMENTARY 12/10/72 07:50 CST 82:57 GET MC308/2 

CAPCOM Or erratic current usage? 

SC We'll think about that, Bob, but 

offhand none of us can remember doing anything like that. 
CAP COM Okay, copy that. 

CAPCOM Omni, Charlie, 17.

SC Are you leaving us, Bob? 

CAPCOM That's affirm, he's already left. 

SC Boy, he doesn't stick around long, does he? 

And he wanted to read that PAD to me, well that's too bad. Okay 
Gordy, I can take the pad now. 

CAPCOM Okay, Jack. It's pericynthion plus 2 SPS/G&N. 

Weight is 66 373 plus 118 minus 014, ignition time is 0 90:49:55:82,

CAPCOM That's correct. 

CAPCOM Need omni Delta, now.

CAPCOM Roger, switch to OMNI Alpha. 


APOLLO 17 MISSION COMMENTARY 12/10/72 08:10 CST 83:17 GET MC-310/1 

CAPCOM America, Houston, I have the morning news at 

the convenient time. 

SC Fire away, Gordo. 

CAP COM Okay, first of all the weather. It's raining 

fairly - fairly heavily all night, there's a lot of water standing 
around. Temperatures here are in the high 50's, but it's 
supposed to get a little cooler tonight with a low in the 40 T s. 
I think you know how the Dallas-Redskin game came out, only thing 
additional mentioned here is that chances look good now that 
Washington and Dallas may meet in the rubber games where the 
National Conference representative in the Super Bowl. In the 
other pro game yesterday, a field goal by Don Cockroft was the 
difference in a 26 to 24 win by Cleveland over rival Cincinnati. 
Other sports highlights, the Pittsburgh Steelers play the Oilers 
today in the Dome, other big games will be Atlanta at San 
Francisco, Green Bay at Minnesota, and Baltimore at Kansas City. 
Tennessee State beat Drake University in the Pioneer Bowl 29 to 7. 
And East Texas State Carson-Neuman in the NAIA football playoffs. 
The Southwest Conference has pulled out of the U.S. Olympic 
Committee. Some college basketball scores: The Houston Cougars 
routed Xavier last night out at Hoffheinz Pavilion 114 to 73 and 
Rice downed George Washington 93 to 89. Gene, you'll be glad 
to hear Purdue ripped TCU 101 to 70 and it was Texas over 
Oklahoma State 86 to 66 and SMU over Oklahoma City 106 to 83. 
We couldn't find any score on Cal Tech, Jack, but switch to 
omni Bravo, please. But one final score, Ron, Kansas lost to 
Iowa 69 to 56. The only thing new on the plane crash Friday in 
Chicago it's reported here that the plane apparently waved off be- 
cause another plane was still on the assigned runway. The 
Democratic Party's stormy session in Washington saw the old 
guard Democrats apparently take back control of the Party from 
pro McGovern forces. Mrs. Jean Westwood was replaced as party 
chairman by Texas lawyer/business man Robert Strauss. Former 
president Truman appears to be more than holding his own at a 
hospital in Kansas City. There's a good chance the 88 year 
former chief executive may be taken off the critical list. There's 
been a one day interruption in the secret peace talks between 
Dr. Henry Kissinger and Le Due Tho. The two conferred for over 
3 hours yesterday. Both sides have agreed not to talk to news 
men on any substantive matters. In other news highlights, Presi- 
dent Nixon has named Daniel Moynihan as U.S. Ambassador to India. 
And Chilean President Allende has flown to Cuba to visit Fidel 
Castro. Here's an interesting one, a 45 year old pilot lost in 
the Arctic for 31 days has been found alive and well. Three 
companions were killed. And Soviet party boss Leonoid Breshnev 
has delayed a scheduled visit to the U.S. It looks as if the 
visit may come in the fall rather than this coming Spring. One 
last note: The news media says the flight of Apollo 17 is the 
smoothest on record so far, and I call that last one pretty ac- 
curate reporting, over. 

SC Thank you Gordo, appreciate the news. Sounds 

like things are still happening down there. 

CAPCOM Got some more parochial news here -

SC Okay, hydrogen purge is complete. Heater is 

going OFF. 


SC Gordy, it looks like the cloudiness and 

possibly the showers associated with the intertropical 
conversions over Africa are moving as far south as Johannesburg 
right now. It's quite a distinct change from even an hour 
or so ago - a couple of hours ago. They're down into an 
area where, presumably they're not normally found and 
vegetation indications are any criteria. And also in the 
Atlantic - South Atlantic near Goa Island there seems to be 
a possible storm developing as part of what was probably 
now a fairly weak front. And whether or not that will 
develop into anything and move in towards Capetown is hard 
to say at this time. 

CAP COM Rog, Jack. 

SC . It looks as if our old friend at 

Ascension are enjoying a fairly nice day out there. 
CAP COM Roger. 
CAPCOM Omni Delta, please. 

CAPCOM Jack, this is Houston. We recall you 

mentioning the purge complete and the heaters off. We just 
wanted to be sure that you did leave the H2 purge line 
heaters on for 10 minutes after terminating the purge. Over. 

SC Thank you, Gordy. I'll turn them back 

on . 


SC Who's sitting over there reminding me of 

all these good things this morning? 

SC Well, that was a combination effort by 

John Arron and Charlie Dumis. 

SC Wow, you've got a real powerful team 

the re . 

CAP COM You bet . 

SC Hey, you really^ ought to get them a 

cup of coffee though sometime this morning. 

SC Gordy, also curious who's watching 

Challenger this morning? 

CAPCOM Well, let's see. 

SC Not much to see, I realize, but i'm 

sure somebody's there. 

CAP COM We need omni Charlie, Jack. 

CAPCOM Well we've got the first team on - the 

gold team - your LOI and landing team and the LM guys are 
Merritt and Thorson.

it ? 

CAPCOM Merlin. 

CAPCOM Merlin, the Magician. 

SC I'm sorry Gordy, you clipped off the 
first again. 

CAPCOM Merlin Merritt, the magician. 

SC Oh yes, of course. As I recall he's 

the only one that really understands Thorson. 

CAPCOM He says he doesn't think anybody under- 
stands Thorson. 

SC Well, we're sure looking forward to 
having a chance to make those guys work a little bit. 

CAPCOM They say - well - Merlin says he is too. 
I don't know about Thorson. He's out of the room at the 
momen t . 

SC He probably spilling coffee in SPAN. 


CAPCOM We need omoni Delta now. 

SC Gordy, for some reason it's a lot easier 
to tell the difference between the Antarctic continent and the 
ice packs. 

CAPCOM Roger. 

SC Maybe the glossy sun is picking up the 

breaks in the ice pack and giving it a different appearance.

SC The continent itself, all you can see 

are very - what appear to be very gentle differences, or 
subtle differences in shading, possibly indicating rolling 
relief due to a photometric dark beam along the - as a 
function of opal phase angle. 


SC And except maybe for the area just - 

oh, I don't know, even there it's hard to - it looks like 
the whole visible continent is clear of clouds this morning. 
Possibly some clouds just east of the Ross Sea, which is 
just coming into view I think. 

CAPCOM Roger. 

SC I know we don't have many listeners in 

Antarctica, but it looks like they're having a exceptionally 
fine day over the portion of the continent we can see. 

CAPCOM Roger. 

SC That weak front I mentioned in the south 

Atlantic stretches from the apparent storm center around 
Goa Island - I'm not sure about that pronunciation either 
up just through the coast of South America from Brazil, where 
it reaches its maximum eastward extent. 

CAPCOM Roger. 

SC Our sub - our zero phase point of the 

spacecraft is in the middle of the South Atlantic. And it's 
moderately bright. Although, there is no central bright 
point at all - a fairly large area, but moderately bright. 
The sea down there might be moderately choppy or rough this 
morning . 

CAP COM Okay. 

SC Ho us t on, 17. 


SC Okay, Gordie. you might say uh before 

you start your sentences cause you're clipping your first 
word. The question I had was the pan camera - we're on 1-6 
of the experiments checklist and need your word on whether 
you want the pan camera off at this time, self test off. 

CAPCOM Stand by. 

CAPCOM We'd like to leave it in heaters. 

SC Okay, we're leaving It in heaters. 

SC Okay, Houston. The S-band AUX TV is 

going to science and I turned the IR on. 

CAPCOM Jack, we'd like OMNI ALPHA. 

SC How do you read on OMNI ALPHA?

CAPCOM Roger. We're still locking up on the data. 

We'll give you a cue. 

CAP COM Okay, Jack, you have our cue for pan camera 

power to power, 

SC Okay. Pan camera going to power. Okay, 

Gordo we're in the SIM BAY door jet attitude. 

CAP COM Roger.

SC Pan camera power Is going to boost. 

CAPCOM Roger. 

PAO Velocity 3763 feet per second. Next major 

maneuver is Lunar Orbit insertion, which presently is scheduled 
for 88 hours 54 minutes 22 seconds ground elapsed time. Total 
DELTA-V or change in velocity which will be retrograde of 2988 feet 
per second. Service propulsion system engine burn time of 
6 minutes 38.08 seconds. Mother Earth is 206 059 nautical miles 
behind Apollo 17, and locked up on the high-gain antenna at this 
time so we should have fairly good communications all the way 
through the SIM BAY door jettison and until the spacecraft passes 
behind the Moon prior to the Lunar Orbit 'insertion maneuver, 
which now is some 4 hours and 37 minutes away, roughly. At

hear that pyro going, I think. It's rotating at about 5, - 
about 1 revolution per 5 seconds. 

CAPCOM Roger. 

SC And it's rotating, what about the long 

axis? Yeah. Rotating about the long axis. 

SC Houston. The garbage that I said went with 

it was just a small amount of debris, I'm sure on the sealant pyro 
area. There was one, oh about a 4 foot length piece of oh, 1 or 
2 in. tape- like material that also went out with it.

PAO This is Apollo Control at 85 hours 45 

minutes ground elapsed time into the mission of Apollo 17. 
Presently 7900 nautical miles out from the Moon and approach- 
ing at 4009 feet per second. We're still about 3 hours and 
8 minutes away from lunar orbit insertion manuever, which 
will place the Apollo 17 spacecraft into a 52 by a 170 nautical 
mile lunar orbit. Earlier today, Gene Cernan asked Mission 
Control for suggestions concerning his gas symptoms. A de- 
cision has been made for the flight surgeon to consult pri- 
vately with Cernan to discuss these symptoms. There's no 
indication that this situation will have any effect on the 
progress of the mission. A summary of the conversation will 
be released shortly. Meanwhile, for distance back to earth, 
Mother Earth stands some 208 068 nautical miles behind Apollo 
17. We have 2 hours and 56 minutes remaining until the first 
loss of signal as Apollo 17 passes behind the Moon. 3 hours 
and 7 minutes and 50 seconds until ignition on the lunar orbit 
insertion maneuver, which presently is scheduled for a ground 
elapsed time of 88:54:22. Total burn time on the SPS engine 
of 6 minutes 38 seconds, for a total velocity change in retro- 
grade of 2988 feet per second. At 85:47 ground elapsed time 
this is Apollo Control. 

PAO This is Apollo Control 85 hours 50 minutes 

ground elapsed time. Here in the Control Center, the Flights 
Dynamics Officer Jay Green, just passed up to the Flight 
Director Neil Hutchinson, the latest predicted figures for the 
S-IVB impact. The present predictions on time are for the 
S-IVB to impact at ground elapsed time of 89 hours 39 minutes 
43.4 seconds. The coordinates of the impact are predicted to 
be 4.12 degrees south latitude by 12.22 degrees west longitude. 
3 hours and 3 minutes to lunar orbit insertion ignition. 2 hours 
51 minutes until Apollo 17 passes behind the Moon for the first 
time. Distance from the Moon, presently 7653 nautical miles, 
velocity ever increasing, now 4032 feet per second. At 85:51

talking about a sliver of the Moon, that is a sliver of a 
sliver. Gordo, we're coming in right down on top of it.

PAO This Is Apollo Control at 87 hours 

16 minutes ground elapsed time in the mission of Apollo 17. 
Some 1 hour and 38 minutes until ignition on lunar orbit 
insertion. Presently, the spacecraft is 4243 nautical miles 
away from the Moon. The Moon is getting larger, as noted 
by the crew. They considered closing the window shades in 
the spacecraft. Velocity now 4544 feet per second. Some 
numbers on acquisition of the spacecraft. With the burn - 
a normal burn, the acquisition on the east limb of the Moon 
would be at 89 hours 16 minutes 29 seconds. Without a burn, 
it would be somewhat sooner, 89 hours 7 minutes 46 seconds. 
A private conversation was conducted with the Apollo 17 crew 
from ground elapsed time of 85:46:55 to 86:04:46. The sub- 
ject of the conversation was Gene Ce man's request for sug- 
gestions concerning alleviating some gas symptoms he had had 
during the flight. The following is a summary of the con- 
versation. The call to the crew was made by Donald K. Slay- 
ton, Director of Flight Crew Operations. Dr. Royce Hawkins, 
Chief of Medical Operations at MSC asked Cernan to explain his 
symptoms. Cernan reported it was no great problem, but 
that he has had some greater gas discomfort then his fellow 
crewmembe rs . He said he felt quite fine at this time, and there 
was never any pain or nausea associated with the discomfort. 
Cernan advised Dr. Hawkins of the anti-gas medication, 
symethocone, he'd been taking. Dr. Hawkins recommended to 
Cernan that he continue the medication after meals and be- 
fore going to sleep. Hawkins also advised Cernan on some 
changes to his menu over the next 2 days to reduce the dis- 
comfort. Cernan reported quote "I'm better, there's nothing 
detrimental or incapacitating about this; we're all in good 
shape. We hope things are looking as good down there as 
they are up here." close quote. Lunar Module pilot Harrison 
Schmitt reported the crew had encountered some difficulty 
with the onboard system that separates gas bubbles from the 
drinking water supply. Schmitt was advised that the gas 
separator system has given the crews problems on previous 
Apollo flights. Astronaut John Young Commander of the 
Apollo 16 mission, and Back-up Commander for Apollo 17, 
also, talked briefly to the Astronauts, and wished them 
well. Distance now 4125 nautical miles from the Moon. 
Velocity 4570. Still an hour and 35 minutes, mark, until 
ignition on lunar orbit insertion burn. At 87:19, this is 
Apollo Control. 

SC Gordo - The widest - most part of the 

convex horizon probably covers a good couple of degrees. I 
can now see relief on the horizon itself against the dark

any reason not to start the checks in about -

peak or range in there must undoubtedly be that inner 
ring, but the way it was lit up in the central range.

glycol pump, and I neglected to make a check on evap temperature, 

do you have that and did we get a decrease?

SC Okay, Houston, I'm going back to SPS pressure 
indicator 1. 


CAPCOM America, Houston, we still see the UV door 

open. Have you closed it yet? 

SC Okay, it's now closed, Gordy.

big old Moon again, and from where I sit it looks like we're right 
on target. Fifty miles above target, I like to add. 

CAP COM Okay, that sounds good. 

SC The limb is, of course, still growing and a 

little more rapidly. And what I can see of the limb that's not 
blocked out by the sun, it's getting obviously much larger in 
the window. 

CAPCOM Roger. 

SC Now I guess it depends on the shadowing of the 

sun as to whether or not we're going to see too much. I think retro- 
grade, we ought to see quite a bit once we get over the terminater.

our relative speed is to the moon at this time? 

CAPCOM Yes, it 5 thousand feet per second. 

You're presently 26 hundred and 60 miles up.

is too. I don't know if John saw this coming in on 16 but 
I know they can recall what we saw leaving on 10 and other 
than the fact that you can't see as much of the Moon it's 
just as impressive. 

CAP COM Rog. I was just talking to John about

monocular now. You can really see down in the depths of some of 
the larger craters, with a great deal of clarity. And you can 
see the - some of the higher ridges actually rolling right over 
the horizon as they go away from you. 

CAP COM Rog, Gene. 

SC Hey, Houston, as much as I hate to, I think 

we're going to have to maneuver out of this attitude. 

CAPCOM Rog. As you take your last look there, your 

presently 20 - just a little over 2000 miles up and your coming 
down about 4500 feet per second. 

SC Gordo, there's only one better view than 

this . 

CAPCOM What's that, Gene? 

SC Right at the moment, anyway. Right at the 

moment anyway, is to be out there and watching this spacecraft 
maneuver in attitude and - and watch it burn over the Lunar 
Surface. I get the feeling someone is watching. 


CAPCOM Give us OMNI Charlie, please. 

CAPCOM Apollo 17, Houston, we just had a site 

handover. That resulted in the LOS time changing 19 seconds. 
It's now 43:21. 

SC Okay, 43:21 and we are on OMNI Charlie. 

CAPCOM Roger. 

SC And, just to round out things as we pitch 

back into LOI attitude, low and behold from over the top of the 
LM came the Earth. 

CAPCOM Very good. 

SC Got the whole thing in one big package. 


APOLLO 17 MISSION COMMENTARY 12/10/72 13:07 GST 88:14 GET MC-328/1 

SC Pretty interesting, Gordo, we can - we can 

see we're right over South America and, of course, we can see 
up the Gulf Coast. And it looks like Houston is covered with 
clouds, but poetically enough, we can see the Cape, at least we 
can see Florida. 

CAPCOM How about that. 

PAO This is Apollo Control, 88 hours 17 minutes 

into the mission of Apollo 17. Some 26 minutes now until Apollo 17 
passes behind the Moon, coming up on the lunar orbit insertion 
burn in which the spacecraft will start its initial orbit measuring 
52 nautical miles by 170 nautical miles, an elliptical orbit around 
the Moon. That maneuver will take place at a ground elapsed time 
of 88 hours 54 minutes into the flight, and will slow the space- 
craft down considerably from its present velocity of some 5 700 feet 
per second. Presently, the Apollo 17 spacecraft is 1528 nautical 
miles out from the Moon, approaching at 5730 feet per second. 
After the spacecraft passes behind the Moon 25 minutes from now, 
assuming as successful lunar orbit insertion burn, it should come 
from behind the east face of the Moon, the limb of the Moon, at 
approximately 33 minutes later. It'll take a few moments for the 
ground stations to lock up on the downlink from the spacecraft 
even though the theoretical contact time is roughly 33 minutes 
after loss of signal. At 88 hours 18 minutes ground elapsed time, 
this is Apollo Control.

PAO This is Apollo Control at 88 hours 43 

minutes into the Mission of Apollo 17. We have had loss of 
signal as Apollo 17 coasted behind the Moon on the start of 
the first lunar orbit, 10 minutes and 28 seconds away from 
lunar orbit insertion maneuver. A retrograde service pro- 
pulsion system burn of some 2988 feet per second. Assuming 
a successful burn, the spacecraft should come out from be- 
hind the Moon at 89:16:29 ground elapsed time as Gene Cernan 
promised it would before they went behind the Moon. At loss 
of signal, the spacecraft was some 395 miles above the sur- 
face of the Moon, traveling at a velocity of 7241 feet per 
second. 9 minutes and 30 seconds - mark, until LOI ignition.

PA0 This is Apollo Control at 89 hours, 15 minutes 

ground elapsed time. Some 55 seconds until Apollo 17 comes from 
behind the Moon, on the start of the first Lunar Orbit. 
We're awaiting appearance of the spacecraft and word that the 
bum went successful, which apparently it has because the space- 
craft without a burn would have appeared some 8 minutes ago. 
The ignition time is 88:54:21 in ground elapsed time. Should 
be getting lock on fairly soon, zero. That was the theoretical 
acquisition time. Of course, it does take a few seconds for 
the ground station to lock onto the signal from the spacecraft. 
We're awaiting word from the communications officer that we have 
indeed gotten a signal and telemetry from the spacecraft.

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 14:08 GET 89:15 MC-330/2 

CAPCOM Very good. We've been hearing you for a 

couple of minutes now. We've had a ground site problem, but 
you're loud and clear now. 

SC Okay. That's what we sort of thought, Gordo. 

The SPS burn could not have been more nominal. I've got some 
numbers for you if you're ready to copy. 

CAPCOM Go ahead. 

SC Okay, TIG was on time, TIG was on time, burn 

time was 6 plus 33, VG is 29899, Roll was 008, Pitch 357, Yaw 
006 , all at the end of the burn. Residuals minus .3, plus .1, 
and 0. Delta VC was minus 6.8, oxidizer 34.0, fuel 34.5, 
unbalance is 110, decrease. The CMC holds us in a 170.3, by 

CAP COM That sounds great Gene. 

SC It was an auto ignition. It was an auto 

shutdown. I think any comments during the burn are on the 
tape. But, to me, it was probably the smoothest and quietest 
SPS burn I ever remember. 

CAPCOM Roger. 

SC Houston this is Jack. The PUGS was erratic, 

and the only thing that I noticed that was off nominal. It - It 
bounced around a lot, in bouncing around - it was initially for 
about a minute around oh, 1.8 decrease, then it gradually started 
to divert from that to a more decrease down to about 2.5 or make 
that 3 decrease. And I went to decrease on the switch and about 
the time of cross over, I had it at oh about 1 decrease and it 
crossed over and stabilized at zero and I went to normal and it 
stayed there the rest of the burn. Until just near the end it 
started to go decrease again. 

CAPCOM Okay, we copy that Jack. 

SC (Garble) 

SC Okay, Gordo, did you by any chance get the 
S-IVB impact? 

CAPCOM Ah, we're - Okay, the new impact time for that 
is 89:39, so we haven't quite got there yet. 

SC Okay. Thank you. 

SC And, Houston, Ron here. I think a little bit 

of a surprise to me when I turned on bank-A the chamber pressure 
came up to 87 percent, and stayed there esentially. Five 
seconds later I put on bank B the chamber pressure rose to a 90 - 
about 91 or somewhere in that area. And then, throughout the burn 
chamber pressure increased which you'll see on the strip chart. 
But I was sure surprised that only 87 percent when we started it. 
It looked like the velocity gained versus time was correct throughout 
the burn, though. The maximum the chamber pressure ever got to was 
about 97 percent, and that was toward the end of the burn. 
CAPCOM Roger, Ron.

go back to VOX. 

SC (garble) 

SC Yeah, enough tourist activity. 

SC Warm in here, isn't it? 

CAPCOM America, a couple of items. Would you 

verify the S-band AUX TV switches in the science position. And 
one other thing, we think you were in low bit rate during 
the burn. 

SC Okay, it's in science and we very 

definitely were in high bit rate during the burn by the 
ch ecklis t . 

CAPCOM Roger, we may have a problem there because 

it looks like low to us on the data. We'll check further. 

SC Hey, Gordy, there was - Ron questioned - 

brought up the question or possibility of not having gone 
to command reset, but just before we left you, you'll 
probably be able to see that I went command reset and turned 
on the tape cause I remember seeing the tape motion. 

CAPCOM Okay, Jack. We're discussing it - what 
happened there. 

SC Okay. 

CAPCOM America, you can go back to VOX. 

SC Okay, Houston. How do you read 17? 

CAPCOM You're loud and clear, Jack. 

SC Okay, before we really got concentrat- 

ing on the burn, and I had an opportunity to - we all had 
an opportunity to look at Korolevb, at a very low grazing 
sun, one of the striking things was the - to me was the ex- 
treme absence of relief, the very smooth surface that ex- 
isted in Korolev, independent of course, of the craters 
that are penetrating that surface. It looked like there 
was a ring in the floor next to the wall about maybe 1/6 
of a crater radius that was somewhat brighter at the low 
grazing sun, suggesting it may have had a different slope. 
And I believe I'm correct in saying that the inner floor 
may be slightly raised. We'll try to make other observa- 
tions this next time around on that one, but there was just 
a very smooth floor, the light plains material in that 
crater is very smooth. 

CAPCOM Okay, understand. One quick word from 

FAO' s (garble) film watchers here. 

SC And of course that's independent - - 

CAPCOM Has to do with optional photographs. 

We'd rather you take the optional photographs on either, 
00 or PP and reserve KK for the scheduled photographs. 
And as it stands now, we've got to reserve 80 frames on 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 14:38 GET 89:45 333/2 

either 00 or PP for scheduled photography. Over. 

SC Okay, you have to keep track of that. 

We need, I was hoping we had an optional capability on our 
first Rev and we'll work it out. 

CAPCOM We do, we just want to put them on 00. 

SC (garbled) 

CAPCOM That's right, just put them on 00. 

CAPCOM Jack, the problem on the high and 

low bit rate there was a syncroniz ation problem between you 
the burn check and us on the ground on our pre LOS command. 
No hardware problems, and I don't think it will be a problem 
in the future. 

SC Okay. But you did loose the high bit rate 

Is that correct? 

CAPCOM That's affirmative. We just had low 

bit rate during the burn. 

SC Okay. 


APOLLO 17 MISSION COMMENTARY 12/10/72 GET 89:55 CST 14:48 MC334/1 

Sc Okay, I may have jumped the gun on you there a 

little bit, but, I thought we were suppose to do that just before 
we went AOS, LOS. I think I did it about a minute before. 

CAPCOM Okay. It was almost identical, simultaneous 

with our sending the command. You've got about 4 minutes to start 
looking at Copernicus coming here. 

SC Okay. Thank you. We're just, Sun's just 


SC Okay, I have a visual on Copernicus. 

CAP COM And, by the way, the S-IVB crunched in on time 

and it's been ringing the ALSEP seismometers like mad for some 
time now. 

SC VOX, and that's VOX. How do you read the LMP , 

Gordy ? 

CAP COM Loud and clear, Jack. 

SC Thank you, Okay, good. Allright I've 

got a visual on Eratosthenes and Copernicus. The, they're are ob- 
viously different age craters in this light. You can see the ray 
patterns in Copernicus moderately well. You can even tell that 
they do cross Eratosthenes. Stadius shows up as a very clear 
dark area to the southwest of Eratosthenes. Now, one of the things 
that we mapped on the southeast and south rim of Copernicus were 
dark albedo areas within the ejecta. And those are apparent, 
here very clearly. And also, within, on the upper portion of the 
rim and on the benches, in that quadrant, the walls, there are the 
dark spot lower albedo material that we mapped. They are, ... 
form linear patterns along the benches apparently. Although, the 
topography is not too clear, but the dark spots are in arcuate and 
linear arrangement, parallel to the rim. And they appear to have 
be elongate along radius. Along the radius of the crater. 

CAPCOM Roger, Jack. 

SC This is in the southeast, southeast quadrant 

I'm referring to. Copernicus H is also very obvious as a dark 
rimmed crater, relative to the albedo or the ejecta blanket. And 
the northwest quadrant, which we mapped as a smooth floor material 
and somewhat darker albedo is just as apparent here, although all 
the contrasts, of course, are less. The main thing that you can 
pick out in earthshine are albedo distinctions. Now, now we, I 
remember that we also at one time, and I can't remember whether 
it made the final map or not, mapped an arcuate fall structure, 
based on the change in albedo. And this was on the southwest 
quadrant of Copernicus. And that across the southern rim, more 
or less north/south, went down and curved across the floor and up 
the southwest rim, and that is a very clear arcuate pattern in this 
lighting. Darker albedo than the rest of the crater, and along 
the arc, there appear to be a couple or three even darker spots. 
Much as we thought we saw in some of the early photography. 

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 89:55 CST 14:48 MC334/2 

CAP COM Roger. 

S C There is a general streaking, radial streaking, 

withing that arcuate dark area, that radiates, radially from the 
crater, and if I had to project, the dark area would, north, 
whose northeast terminus is the arc in the crater, I'd project 
it off to southeast about crater diameter and a half, maybe. Now, 
we're getting, essentially directly overhead, and again the dark 
spots within the crater wall are still apparent and the streaming or 
the radial elongation of these spots is clear. Now, on the lower 
wall, that's below the first bench, I can see four of these dark 
areas, and on the next wall above that, above the first bench, 
there are two, two obvious ones, and a couple that are somewhat 
more subtle. 

CAP COM Okay. (garble) 

about in the Central Peak? 

SC No, Gordy, I can't. There's very little in- 

dication of relief in earthshine and particularly at this high 
Sun angle, high Earth angle. Pardon the expression. 

CAP COM Roger. 

SC The Central Peaks do stand out, though, as 

a much lighter albedo area within the crater. It looks to me 
like the best thing you can do in earthshine is work with albedos. 
Knowing the general topography from the, from the earlier photo- 
graphy. We're coming up on Kepler, now. Copernicus is out of my 
view in window 5. Maybe Ron sees it. Do you Ron. 

SC No, it's out of my view now too. 

SC Okay , we, we . . . 

SC Can you see Reinhold over there? 

SC Reinhold, I was not conscious of, yes, I can 

see Reinhold. Reinhold is one of the craters just like Copernicus 
that may have contributed ejectas in the Apollo 12 files. You see 

SC And S-IVB, yes 16 ' s S-IVB hit out there to the 

south, I think. 

Sc Well, I don't see anything that would indicate 

that . 

SC Reinhold is an (garble) aged crater, as you 

may recall. It's crossed very obviously, even in this light, by 
the Copernican rays, which is prime, the main way we determine 
the age, other than it doesn't have any rays itself. Although, 
on the good photography we now have, we know it has secondary 
crater patterns around it. 

SC You're not looking at the same crater 1 am 

th en 

SC Reinhold is right down here Geno. 

SC Where are you looking? 

SC Well, it's south of Copernicus. 

SC Okay, I'm looking up here. 

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 89:55 CST 14:48 MC334/3 

SC South and a little west. 

SC I don't have the same view you have. 

S q Okay, I can see Lansberg now. And I'm afraid 

I can't shed any light, pardon the expression, on the old question 
we've had about the age of Lansberg, relative to the Mare. 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 14:58 GET 90:05 MC335/1 

CAP COM Okay. 

SC Kepler Ray pattern is very striking in this 

light and the (garble) series of bands which only average being 
radial. In most cases they're a little off the radial," but by 
joining together, they give you a general radial pattern. I just 
want to see a -- okay, out the window 4 I have an excellent view 
of Kepler. Once again, albedo differences, such as the -- are 
very clear -- such as the distinction between the wall light -- or 
brighter wall materials, and the rim, which in itself, is brighter 
than the surround mare. We can look right down some of the rays, 
and the rays are not completely linear. I'm looking now to the 
northwest. Gene, you could see Aristarchus way up there in the 
northwest. See it? 

SP Yeah (garble) 

sc You ought to have a good view of Aristarchus. 

Very bright up in the northwest part of our field of view. 

sc The inside of that crater almost looks as if 

it's backlit . 

sc That's right. Well, it should be. Strangely 

enough . 

sc And, but -- these rays with contrast to the -- 

maybe the feeling one would have that they are -- once they get 
started, they form a linear pattern across the surface. They 
don't seem to have done that. 1 As a matter of fact, they're quite 
strikingly curved along their pattern. They'll break from the 
general radius they're out on, curve away and then curve back. 
Some — all -- let's see, there are 1, 2, 3, 4, 4 rays that go 
from out -- to the northwest of Kepler, all of which show that -- 
nonlinear characteristic. 

sc Yeah, they're all radial, though. 

sc They are radial, in general, but when you 

look at them in detail, only portions of them are radial, and a 
single ray which you could follow continuously, will bend then 
curve back. 

sc The it's unique. We've got rays from -- 

I guess those must be Copernicus over here -- those long ones off 
to the right, which you might not be able to see. Kepler and 
Reiner are all intermingling up here. 

SC Yeah, this is the area now we're going over 

where the gamma ray work on 15 indicated a relatively high radio- 
activity. And -- not yet, it's -- (garble) 

SC Houston, America here. Do you see the torque 
and angle? 

sc I was going to look for the Hortensian Domes 

near Copernicus, but got sidetracked with Kepler and missed them. 

CAP COM (garbled) Ron. 

sc They are not obvious, though, in looking in 

the gen -- Okay, our torque 845. 

CAPCOM Roger. 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 14:58 GET 90:05 MC335/2 

SC Okay, we're getting out into Pro cellarum — 

Oceanus Pro cellarum proper now, and before long, should pick up 
the medial ridge that makes that mare so distinctive from the 
other mare. This is a ridge that stretches something like 
2000 kilometers north to south, if you want to tie a vari -- a 
number of things together. And, probably is the lun -- the Moon's 
closest analogy to an oceanic ridge, which has -- which have been 
in the news over the last decade. 

CAP COM Roger. 

SC Once again, the topography of the Procellarum 

Mare is not clear in this light. It's just not quite enough 
light to give you strong, distinct shadows. At least, not yet at 
this Earth angle. 

CAPCOM Okay, and as you get the camera set up for the 

orbital science pictures of Galois with -- on a change, and use 
Magazine 00 instead of KK. That's listed in the flight plan at 

SC Okay, we'll do that. 

SC Okay, out of the window 4, I'm able to see 

some of the Rima gamma materials, and it's awful hard to say 
more than just the fact there is a very clear light-colored 
pattern off to the north. Of our position, at any rate. I think 
all I can say is that I've seen it. I can't give you much informa- 
tion on it. 


SC We can see the area where Maurius Hills 

should be, although it's not an obvious topographic feature in 
this light. Still see Aristarchus off up there shining like a 
star, if the Moon could have stars, 

SC Okay, Houston. I'm going to torque those 

course line errors out at 12. 

CAPCOM Roger, Ron. 

SC And — You squared away? 

SC It's good to be able to see some stars out of 

the telescope. It's the first time I've been able to see any. 

SC Gordie, we have a very clear zero phase 

point for the Earth light. It's certainly not a strong contrast 
for the Sun, but it's out there, and within it, again, the French 
craters tend to brighten quite a bit more than the surrounding 
mare. Still looking at Oceanus Procellarum. And, now, out 
Window 3, up to the northwest, Grimaldi is starting to show up. 
A very obvious dark area within the highlands of that part of 
the Moon. And, one of the darkest mare regions that we have seen 
on the Moon. It's comparable, at least in the photographs, to 
that of Tsiolkovsky. Normally, of course, we think of the dark 
mare as being the younger basalt flows on the Moon, but in our 
case, of course, young means something on the order of three 
billion years or older. 


/XU/7 2 CST 14:58 GET 90:05 MC335/3 

CAPCOM Roger. 

sc For out interp -- If we can extrapolate from 

the samples returned by other missions. It's amazing how far 
over you know the highlands to the west of Procellarum are still 
are bright, and the contrast between fresh craters and the normal 
highlands are very obvious still in Earth light. Particularly, 
along the zero phase point with respect to the Earth. 

sc Rima Gamma now is coming a little bit closer 

to our oval track in the horseshoe in the larger and more western 
end of it; the dark horseshoe is quite clear in this light. It's 
a west or northwest pointing horseshoe. As is the complete trend 
of that strange feature. I think Ron is going to have an excel- 
lent change to study these light-colored swirls within the mare 
and other parts of the Moon. We had some good views of them and 
Mare Marginus -- 


APOLLO 17 MISSION COMMENTARY 12/10/72 15:08 CST 90:15 GET 336/1 

SC very marginous and to the east of Mare 

Crisium, if there is anything to be seen, he should be able 
to see it during the next few days. 

CAP COM Rog Jack. 

SC Say, Gordo, something I just noticed here 

in working with the GDCs we're having, I looked at the PC 
gage and at a PD, PC position, why there is a continuous 
bias on it now of about, oh, 7 percent and if I switch to 
ALPHA it goes to zero. We never saw that bias before this 
last burn. 

CAPCOM Roger, Gene. 

SC Hey, Gordy, I'm looking right up the 

western edge of the Procellarum Mare where it contacts the 
western highlands of the Moon and we're just about to fly a 
little bit south of Grimaldi. That edge is very irregular. 
There is no obvious indication that it, there are large 
basins that have been flooded by mare that have formed that 
edge and but again the topographic distinctions possible in this 
lighter fall. Now I'm starting to see that there are shadows 
in the craters. 

CAPCOM Roger. 

SC That's the small craters. There in the 

Mare Procellarum closest to Grimaldi there are two arcuate 
rilles. Look like they are probably V -shaped in their cross 
section. I'm sure we've seen those on the photograph much 
better than I can see them here. Those rille patterns though 
do seem to project over into the Highlands. 


SC To the north of that, to the north of that 

B ay of Mare . 

SC Just interrupt. Hey, I just saw a flash 

on the lunar surface. 


SC It was just out there north of Grimaldi. 

Just north of Grimaldi. You might see if you got anything 
on your seismometers. Although a small impact probably would 
give a fair amount of visible light. 

CAPCOM Okay, we'll check. 

SC It was a bright little flash right out 

there near that crater. See the crater right at the edge of 
Grimaldi. Then there is another one north of it. Fairly 
sharp one north of it. It's where, there was just a thin 
streak of light. 

CAPCOM How about putting an X on the map where 

you s aw it. 

SC I keep looking occasionally for Yeah, 

we will. I was planning on looking for those kind of things. 

APOLLO 17 MISSION COMMENTARY 12/10/72 15:08 CST 90:15 GET 336/2 
Starting to see the edge ofOrientale, Gordy. Way off to the 

WeSt " sc Gordy, to the north of Grimaldi there is 

a large basin that is about the same size but only incompletely 

filled with a mare in its northeastern quandrant. The rest 

of it looks like a fairly irregular and hummocky floor material 

of some kind. But it's almost the same size as Grimaldi. 

It even looks like it is a little bit deeper. But, of course, 

Grimaldi has considerable fill. Grimaldi on its eastern^edge 

has some of the grobbens, or it's a rim, if you will, i t s 

cut by three or four anestomozy grobbens. Make it look like 

some of the midge areas in the larger basins. Okay, the 

first ring of Orientale is showing up. The next ring m 

is extremely obvious, got some very bright east facing slopes. 

CAPCOM I'll turn off the innercom. 

sc it has some very bright east facing 

slopes and you can see the bands of Mare that are filling 
the, both the first bench area and the inner bench. Any 
time you need us, Gordy, just interrupt me. 

CAPCOM Okay, we'll do that. 

sc Now, as I look north along the first 

bench, that's the first bench from the out side, one inside 
the Cordillerian ring, better check that. I may have 
my names mixed up. Got a ring caller? Handy? Seat? Should 
be on there. Yeah, this is what I need. What's the name - 
they got a name on that - ridge, there? Ah, that s Rook 
Mountains. Yeah, the Cordillerian. Yeah, that s right and 
looking just west of the Cordillera in the first bench as I 
look north in this light which is casting some shadows now 
Gordy, over in here it looks extremely smooth. Now this is 
not mare, it's lighter albedo, lighter reflectivity then the 
mare and, although there are patches of mare here in the 
lower areas in it. But looking along that plain, m fact 
a large - long linear plain, it looks quite smooth with only 
some very broad undulations that appear to be roughly radial 
to Orientale itself. The closer we get to it the more I 
see minor relief showing up. I start to see the shadows, 
I guess. And that relief seems to bring out a hummocky texture 
in addition to the craters you would expect to see there. 
CAPCOM Roger. 

sc x won't try to give you a trend on the 

hummocks because I think the shadows are biasing my view and 
they do appear to be north south trending but I think that is 
because of the shadow pattern. This is a spectacular sight 
you guys, you ought to take a look at Orientale. One of the 
largest fresh basins on the Moon. It still is probably 
A billion years old, or 3.8 at any rate, if our dating criteria 

APOLLO 17 MISSION COMMENTARY 12/10/72 15:08 CST 90:15 GET 336/3 

are any good. It has the outer cordillerian ring and the 
inner ring called the Rook Mountains. Very, very nicely 
shown. They are massive. On that inner ring, the Rook 
Mountain ring, there are massive complexes much like what 
we'll be studying at Taurus Littrow. There are low areas 
non-mare areas that are comparable to the Taurus Valley that 
we'll be landing in. And all in all I think we'll find that 
our ring in the Taurus Littrow area around Serenitatis 


APOLLO 17 MISSION COMMENTARY 12/10/72 GET 90:25 CST 15:18 MC337/1 

SC Pitatus is comparable in many regards to this 

Rrook Mountain ring around Orientale, You want, - did you inter- 
rupt Gordy? 

CAPCOM No. I didn't say anything. 

SC Okay, I thought I heard your key. Okay, in 

the inner portion of Orientale, as we approach a terminator, the 
lighting is still excellent. As a matter of fact, it appears 
brighter than what we were looking at over at Copernicus. Now, 
part of that may be, we're seeing much sharper relief since the 
slow earth-gacing slopes are nicely lit, and the backfacing slopes, 
of course, are in shadow. The first portion of the bench inside 
the Rook Mountains is partially filled by mare. Now, the higher 
land in there is very smooth, in a gross sense, it's a very smooth 
hummocky terrain, cut by roughly ci rcumf rent i al grabens . The trend 
of the hummock, themselves, are not radial, they're more, well, 
they're about a 45 degree angle to the radius. They, in detail, 
have a much finer hackly texture, much like we've been able to 
see on photographs before. And, in general, you get the impres- 
sion that, in several areas here, that that hackly textured sur- 
face is draped over material that resembles the massifs of the 
Rook Mountains themselves. There's one area just to the north 
now of our track, where there's a large, roughly equidimensional , 
mountain mass, with a few projections of massif-like peaks through 
this hackly textured surface. 

CAPCOM Roger. 

SC There are also some radial grabens, I just now 

picked one up, which we've also seen on the Orientale photographs, 
taken by Lunar Orbiter. It's amazing how fresh appearing this 
basin looks, considering it's great age. But it's, it probably 
is not had any more violent a history than Imbrium. Now, we're 
getting up, just about to go over a delta rim crater that's out 
in the basin. I don't remember the name of it off hand. But it 
should be familiar to some of the geologists who have ampped 
this basin. It does not appear to have a strong Impact ejecta 
blanket around it. It's filled with mare and it's quitely sharply 
in contrast to a crater of comparable size to the northwest. See 
that one Ron. I don't know whether you can get it. I get a good 
view out of 5 now on that one. And, once again, it looks as if 
it's hackly textured material that forms the higher hills in the 
inner bench. It has a draped appearance over the, over pre-exist- 
ing terrain, and in fact, along the ridges of the hummock, we now 
can pick up a little rilles that roughly parallel the hummock, 
although not, not consistently. They do cross down into the 
valley. But has appearance that there may have been a tensional 
relief along the crest of each of the hummocks, or many of the 
hummocks . 

CAPCOM Roger. 

SC Delta rim crater just as has been, I think 

discussed in the literature, has just that. Delta rim with no 

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 90:25 CS T 15:18 MC337/2 

sc obvious ejecta blanket around it, compared to 

other larger craters within the basin. We're directly over that 
crater right now. It's filled with mare, very smooth mare. As 
a matter of fact, within that fill, I can see no, no craters. Get- 
ting very close to the Earth terminator, but you see good texture 
in the ejecta blanket of the large crater in the north part of the 
inner basin of Orientale. The radial ridge and valley patterns 
are very clear, the concentric coarse hummocks near the rim are 
apparent, and you can even see the second, patterns of secondary, 
larger secondaries, extending out away, radially out away, from 
that crater. The south, the mare fill in the south floor of 
Copernicus, I mean of Orientale, is very smooth, but does have 
the sea swell texture that we saw over in Tranquillatatis . 

sc Better let him say something before AOS. 

CAPCOM I ain't got noth ing to say. 

sc I guess we're getting close to AOS. We're get- 

ting close to AOS. Do you have some words for us. 

CAP COM Okay, we show about 9 minutes to LOS . We'd 

like to clarify one thing, and that was on this tape recorder 
commands and high and low bit rate. And we just want to make it 
clear that pre-burn the 6 minute call out is high bit rate, record 
forward command reset. Did you tell us a few minutes ago that you 
did indeed do all those at about 6 minutes? 

sc Yes, Gordy, I surely thought I did, but I can't 

specifically, I know the high bit rate was there, because we switched 
to low later. I can't, I'm afraid I can't specifically verify the 
command reset. 

SC Gordy, I can specifically say that when those, 

after the BUSS stars came on, we called that out. I'm almost sure 
Jack did get it, because I had a bunch at the helium valves and 
the nitrogen, helium and the nitrogen valves. 

CAPCOM Okay. We're just trying to make sure if we, 

to determine if we do have a switch problem, that the INCO did 
sound low bit rate command just prior to LOS there, before LOI , 
which is the way it's called out in the flight plan. And then 
you should have come along later and with a command reset, setting 
the switch to high bit rate, and the command reset switched into 
high bit rate MOV, and for some reason it did not go into high bit 
rate . 

sc Well, you want to test it out here, before we 

go around? 

CAPCOM That's a pretty good thought. I think we will. 

On standby, we'll give you, we'll figure out how we're going to 
do it here. 

CAP COM Okay, Jack. We just now commanded low bit 

rate and you're in low bit rate. We'd like you now to select 
high and command reset. 

sc Okay, Gordy, you also have an oscillation in

on the corner of Lobachevsky. 

CAPCOM Roger, America. 

SC Those frames that Ron mentioned, this is Jack, 

that he mentioned, were taken of an area where there's a much 
lighter gray albedo, rather than the tannish gray, it's pure gray 
material that generally is on the rim crest of a number of craters. 
It may be related to the swirls that we see elsewhere. 

CAPCOM Roger, Jack. 

SC Bob, we're abeam of Al-Biruni, coming up on 

Goddard and Marginis right now. 

CAPCOM Roger, America. We're tracking you on the map 

here, watching it. 

sc Al-Biruni has got a variations in its floor. 

Variations in albedo. It almost looks like a pattern as if water 
were flowing on a beach. It's that irregular. Not in great areas, 
but in small areas, around on the southern side, and the part that 
looks like it's a water washing pattern is of a much lighter albe- 
do, although I cannot see any real source for it. The texture, 
however, looks about the same. 

CAPCOM Roger, Gene. 

SC And to Houston, America. I forgot the (garble). 

It took a minute and 45 seconds for the mapping camera to extend

SC Bob, what's our altitude now? 

CAPCOM Looks like you're crossing, you're just about 

90 miles, but we'll firm that up here, Gene. You're 90.8. 
SC Okay, thank you. 

SC Bob, this is Jack, and the question of these 

irregular swirls that we got in Mare Marginis and we are looking 

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 91:24 CST 16:18 MC339/2 

SC justnorth of Neper now. I tell you, in the 

mare, there just is no visible relief. Although there seem to 
be some similar systematic anyway to the distribution. Like, 
there'd be a very dark area associate with the light area. And 
that dark area is darker than the mare. I think the pictures 
will show that. Now, in the highlands, however, the light albedo 
areas, which are very comparable, that appear to be swirl like 
patterns of the same type, seem to be associated with a crest 
of crater ridges and other high points. We're right over a 
concentration of these now in the northern part of Marginis, where 
the rule of the light areas being associated with the either 
symmetrically around a much darker area than the normal maie , or 
on one side, and in this case, generally the south side of the 
dark area, that rule is very clear. And that also seems to hold 
in the backside, that there was a slightly darker region between 
areas of light colored swirls. 

CAPCOM Roger, Jack. We understand and we're stand- 

ing by. We have a DOI pad and some other updates.

the landing site. 

CAPCOM Roger, understand and roger Ron. 

sc The shadows, Bob, go all the way across 

the Scarp and very long pyramiding shadows go all the way 
past Family Mountain, Looks like the Sculptured Hills are 
lit up on this side, but I'd almost put the entire North 
Massif in shadow from where I stand. 

CAPCOM America, Houston. 

sc Quite an interesting place to land down 

the re . 

CAPCOM America, Houston. 

sc We can now, I think, see contrast down 

in the shadow. And the only part of the Scarp that is visi- 
ble, I think Jack picked it out, as being right where Lara is. 

CAPCOM Roger. America, Houston.

be going through your systems checklist here and you'll

if it s greater than 85 percent and you are at about 89.6 per- 
cent. We d like you not to dump the waste water until the 
nominal time in the flight plan. Do not dump the waste water 
during this systems check. Over. 

„. , SC Okay, and I understand that was about 

94 hours as I recall. 

CAPCOM That's affirmative. That's where the 

nominal time is and that is where we'd like it dumped.

I can see Bare Mountain. I can see - I can't really make 

out the slide yet. Most of the North Massif are still in 

shadow due to the - due to the Sculptured Hills. And just 

at the point where we can start really to see through the 

shadows and see some hummocky terrain on the North Massif. 

It just went out my next reach. But, I did see some sort 

of albedo change that went across the canyon about in the 

vicinity of the scarp.

SC Okay, Houston, there are the torquing angles. 

CAPCOM Roger. We see them. They look good. 

SC Just for another little matter of interest, 

once the Earth Is in the field of view, which it's about, looks 
like it must be about 12 degrees from Regulus, it's so bright, 
that it blacks out any, blanks out the telescope for any star 
recognition. However, it worked real good in the sextant. You 
can see the star real well. You just have to assume it's Regulus, 
tho ugh . 

CAP COM Roger. Would that star angle difference... 

SC Okay, I'll torque at 30. I torqued at 30, 


CAPCOM Roger. We copy. 

SC And the first, the first star angle difference 

was, you know, you can get a little bit lax about it. If you want 
to spend a little time at it, you can get five balls, looks like. 

CAPCOM Roger, Ron. With that star angle difference 

on the second one, I can assume it was Regulus. I think you're 
safe in your assumption.

CAPCOM Jack, just some words from the back room on 

you. The a -- there may have been an impact at the time you 
called, but the Moon is still ringing from the SIVB impact, so 
it's masked any other -- would mask any other impact, so they may 
be able to strip it out at a later time, but right now they don't 
see anything at your called time.

PAO This is Apollo control at 92 hours 

49 minutes. And, we've had loss of signal as Apollo 17 goes 
behind the Moon. During this pass Jack Schmitt saw a flash 
just north of the crater Grimaldi at an elapsed time of 
90 hours 18 minutes and thought it might be a meteor Impact. 
We could not confirm that; however, the Moon was still ringing 
from the S-IVB impact and would mask out other activity on 
seismometer recorders In the science support room here. 
Apollo 17 will perform the descent orbit insertion maneuver 
behind the Moon just after the start of the third revolution 
and at a point near perilune the low point in that revolution. 
Ignition time for that maneuver is 93 hours 11 minutes 

36 seconds. Delta-V change of velocity of 197.4 feet per 
second. Duration of the burn 22 seconds and we anticipate a 
result of robit of 58.9 by 14.5 nautical miles. If the burn 
is performed as expected we'll next acquire Apollo 17 at 

93 hours 34 minutes 24 seconds. If Apollo 17 is unable to 
perform the burn acquisition time will be 93 hours 31 minutes 

37 seconds. We'll come back up just prior to the no burn 
acquisition time and stand by through that period of several 
minutes. At 92 hours 51 minutes this is mission control

SC Houston, this is the LMP. There seems to be 

two general kinds of ray patterns. Those associated with a lot 
of secondaries and light colored and those that have no visible 
secondary. And that's independent, yet, from the irregular 
light colored areas we've been calling swirls. 

CAPCOM Roger, Jack. We're copying. 

SC Houston, there's also a lot more, there is a 

lot more of that light colored swirl like irregular material, 
or discoloration, or whatever you want to call it, in the back- 
side highlands, particularly as we approach Marginis than I 
had previously gathered from the available photography. 

CAP COM Roger, Jack. 

SC And there still seems to be no relief asso- 

ciated with it. Although, in many cases, it seems to follow ridge 
lines, or crater rims partway, in other cases, it's quite irre- 
gular in its distribution. 


SC And Bank A, that time, with the chamber pres- 

sure was up to 95. 

CAPCOM Roger, Ron. And we got tracking data on you. 

It has a 13.1 perigee, perilune rather.

SC Some of the boys might be interested to know 

that in a place where the Sun is just grazing the slope, it's a 
steep slope on the north rim of Crisium , I can see the horizontal 
lineaments that were such a controversy on 15. 

CAPCOM Roger. Understand. The north rim of Crisium?

just got grazing Sun on them, and with the binocs, you can see 
that horizontal lineation pattern.

feeling of that maybe. 

SC Ain't nothing out there. 

CAPCOM Jack, Houston. Can you see any albedo 

difference in the landing site area between the dark massif 
and the light area. 

SC We can't see any difference between - in 

the low areas between the dark mantle and other materials 
right now. We're right at the terminator. Yes, but, Jack 
and I weren't really looking at the landing site. I think 
Ron was . 


APOLLO 17 MISSION COMMENTARY 12/10/72 18:48 CST 93:55 GET 351/1 

SC Gerry, you could really see a difference 

between the South Massif and the mantle material around 
through there. The mantle is not nearly as dark as it looks 
on the pictures though. But the Massif, South Massif, es- 
pecially looked almost a whitish color. I guess it's because 
the, partly the sun's shining on it. But then - - 

CAPCOM Could you see anything that looks like the 


SC Oh, yeah, you can see the slide on the 

thing, definitely see the scarp going across through there. 
I was primarily concentrating on looking for the various craters 
so, I didn't spend that much time, you know concentrating on the, 
how the thing looked. But, in the marks on the thing, the first 
4 or 5 marks were on F crater and then I saw Sherlock 
about half way through it and I got about 5 marks on the Sherlock 
for 17-1. 

CAP COM Rog, Gene. 

SC Houston, in crossing Crissium and 

Marginis it looked fairly clear that with the small fresh 
craters, and I don't have a good size estimate right now, 
I think I'm looking in terms of 100 or 2 meters, you can dis- 
tinguish where blocks have been thrown up by them and are not 
possibly giving depth of the local regolith, from the pictures 
you'll get in there. 

CAP COM Rog» Jack. 

SC And also on that lineation question, 

not only, where the sun grazes a slope do you see the horizontal 
lineations but they're at the southern end of the shadowed 
area on a slope, you get a couple other lineations showing 
up at least in a couple places I saw. one would be parellel 
to the slope, that is cross contour and the other was at 
an angle to that direction, oh, say about 30 degrees, 

CAPCOM Roger, Jack. We're copying you loud and 

clear and no problems with com at all. 

SC Okay, we just had sunset. And Houston, 

America, on Mag Bravo, Bravo, 75 to 70 percent were utilized 
on J3, and F crater and 17 1 through the sextant. 

CAPCOM Roger. Just want to confirm, Ron, you 

started on J3 and then you went to F crater and then 

SC Yeah, I went to F crater and then back 

to Sherlock, or 17 1. 

CAPCOM Roger. 

SC Actually on J3 I took 4 marks on a 

crater that was to the west of J3 and then I finally saw J3 and 
started marking on it.

Apollo 17 is just south of the Oceans of Storm, Ocean of Storms 
now. Shortly, we'll be coming up on the crater Grimaldi again. 
That's where Jack Schmitt saw a flash on the last pass. We're 
showing an orbit of 58.9 by 14.3 nautical miles at the present 
altitude of 28.1 nautical miles. 

SC Hey, Bob, who are you talking us with, Honey- 

suckle or Goldstone? Honeysuckle, I guess. 

CAPCOM We're talking through Goldstone, Gene. 

SC Okay, looks like about a toss-up from here. 

I'll tell you, there is really one heck of a big low pressure 
area developing somewhere off the coast of California, Washington, 
and Canada, out in the Pacific Northwest part of the country. 

CAP COM Roger. We copy. 

SC We were watching it earlier today, but I tell 

you now, it's really carrying in some other clouds with it. It 
must cover an enormous distance and it's got some real spectacular 
ci r cul ation , 

CAP COM Just for curiousity, are you using a monucular 

on that? 

SC No, I'm using a binocular. 

CAPCOM Roger. 

SC Bob, it's, it's got a trailing front. I can't 

really see the states, or even North American continent, because.., 
CAP COM Stand by, Jack, Gene. 

CAPCOM We'd like pretty well 

S C Ok ay . 

CAPCOM Sorry about that. Go ahead. 

SC Okay, I was just going to say, it's got a, 

looks like a tremendous trailing front. Roughly, north northwest, 
south, southeast, and it looks like it may just sweep up the west- 
ern coast. It's hard to tell how far off the actual center rota- 
tion, or even a front is. I just remember from earlier this morn- 
ing, when I could see land masses , that it appeared to me to be 
off the Pacific Northwest out in the ocean.

kicking around with frug, and if you get -- if you want to, dur- 
ing your -- any of your free time, if you have any, you might 
look at Copernicus with your binoculars and see if the dike 
goes all the way across. He would recommend using the binoculars. 
Don't take any of your eat or sleep time at all, but you might 
get a chance on this one eat pass to as you go by there. 

SC Okay. I'll give her a try. You might give 

me a couple minutes warning the next time around. 

CAP COM Okay, Jack. 

sc I'm not sure the attitude is too good for 

that. I wish I'd thought of it this round. 

CAPCOM Uh , Rog. Well, we were pretty busy coining up 

on it this time. I think the at -- that's why we mentioned that 
the attitude may be okay during the eat period. We don't want 
you to break away from the eat period unless you see you can 
spare some time. 

sc Just looking at the southern edge of Grimaldl, 

Bob, and we probably have it covered on photos, but there's a 
nice tangential to slightly circumferential graben along the 
southern wall and climbs out over the western rim and off the 
eastern rim, and that graben is pre-mare, pre-mare. 

CAP COM Okay, I copy on that, Jack, and as long as 

we're talking about Grimaldl, you might just rem - we'd like to 
have you brief Ron exactly the location of that flash you saw. 
We'll probably ask him to take a picture of it, maybe during one 
of his solo periods. 

sc Hey, Bob, before we get awfully involved, 

just let me tell you what our motive is here in the next couple 
of hours. That's to eat and get done what's in the flight plan, an 
come our rest period, we're probably going to turn out the lights 
so make sure everything's done by then so we can start it on time 
tonight .

definitely, Gene. Don't want you to work into your sleep period.

and the word you gave us was that it had -- it wasn't working, 
and we're just wondering if you want -- we're thinking about work- 
ing up a test board to see if -- did you test it out thoroughly 
to make sure it wasn't working, or was that just your desire not 
to use it? 

SC We tried it, Bob, and it did not work. The 

only reason I'm reluctant on a test is that I just don't want it 
to take much time. 

CAPCOM I don't think it would take much time. The 

only thing I could say is it would -- you know, two obvious things 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 19:15 GET 94:22 MC354/2 

sure you checked them, Gene, would be the utility power and make 
sure you had the right lamp tests on when you tried it, and that's 
the only I'm sure you did it, and that's the only obvious 
thing -- maybe a circuit breaker or something like that. 

SC Well, we checked it both on the left side and 

on the right side with two separate utility powers and verified 
that the master alarm came on with the test on both sides, and 
nothing ever happened. 

CAPCOM Rog, I was sure of that, Gene. Just wanted 

to make it clear and put everybody at ease that it's just not 
working. That was essentially the test. Just forget anything 
we said about tests. 

SC Okay. What test? 

CAPCOM Rog. Got you guys trained up there, finally. 

SC Arf, arf. 

SC Houston, America. 

CAPCOM Rog, go ahead, Ron. 

SC If I ever find my scissors here one of these 

days, I think it takes about 4 bolts on either side of the — 
you know the optics, where they stow the optics? It looks like 
there are four little 2-lead bolts that'll come out. And, I 
think maybe they might be back behind there, I don't know. See, 
there's a great big slot up at the top of that, oh, it's at 
least an inch, inch between the top of the optics thing and the 
top of the spacecraft. I looked back in there with a flashlight 
and can't see anything, but it's a big hole back there anyhow. 

SC I think the Commander might have something 

to say. 

SC Hey, Bob, just ignore everything he said. 

We'll leave him a pair of our scissors, and he's just worried 
about being hungry. 

CAPCOM Roger. Those are your EVA scissors, too, 

aren ' t they? 

SC But, he is not — yeah, but we can handle — 

we can handle it with one down there. He is not taking the 
spacecraft apart to find his scissors, and I will not let him go 
h ungry .

Littrow landing site now. 

SC Now we're getting some clear - looks like 

pretty clear high water marks on the - 

SC There is high water marks all over the 

p 1 ace th e re . 

SC - on the north part of Tr anq uil lit ati s 

in here mare onto the highlands. 
CAP COM Roger. 

SC Yes, there is high water marks all over 

that mare - I think that's Miraldi there. Are you sure we're 
at 15 miles up? 

CAPCOM Your at 14.1 to be exact, Ron. 

SC (laughter) looks pretty low. 

SC Gee I wonder what it feels like to be 

at 8 to 10. 

CAPCOM You're going to find out I think. 

SC I tell you there's some mare ridge or scarps 

very senuous just passing one, but not only cross the low 
plainer areas but go right up the side of a crater in one 
place and a hill in another. And it's not at all like a 
false scarp. It's looks very much like a constructional 
ridge. And it has the senuousity of - pardon the expression 
rattle snake. 

CAPCOM Roger. Does it look like that one we 

saw on the track the other day. 

SC Yes, very much like that one that you 

almost caught. There are tons of pressure - several of them 
grabens in here. We must be out on the edge of Serenitatis 
now, right? 

CAPCOM Yes, we show you on the edge of Sereni- 

tatis , Jack . 

SC R°g, I just - we didn't get a view of the 

site, though, going over this time. I think it was off to 
the north of us just a tad. That's the best example of a 
mare like ridge that was as clearly constructional as I would 
want to see it. Out on the mare it's never quite that obvious. 
But there it climbed up over a hill and then back down again. 

CAP COM Roger. 

SC And, that was just east of the - an area just 

east of the edge of Serenitatis and probably a little bit 
south of the landing site. 

SC Say, Bob rather than copy specific re- 

commended changes or deletions to a diet can you have a general 
comment that's any different than what I already understand. 

CAPCOM Right it's no problem. 

SC If not I would rather delay it. 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 20:38 GET 95:45 358/2

SC Okay, pan camera going off. Mark. 

SC Got the uplink. 

SC Okay, Bob. Let's see. Will Copernicus -- 

will be north of our track. Is that correct? 

CAPCOM I believe so from my charts here, but let 

me double check that. That is affirmative. Tommy just gave me 
the up on that one. 

CAPCOM If you guys got time to listen, I can update 

you on the homefront while you're looking out the windows. 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 20:55 GET 96:02 MC360/1 

SC Go ahead, Bob. 

CAPCOM Let's see. For the CDR, they're eating beans 

and cornbread over at Nassau Bay tonight. Probably a good thing 
they're eating beans there, Gene, because you're feeding twenty- 
five tonight. And, the horse is getting fed, also. 

SC Beans and cornbread? It's a good thing I'm 

eating up here. 

CAP COM You better believe it. And, of course, every- 

body sends their love. And, over in El Lago, they're, well -- 
Go ahe ad , Gene . 

SC I was just going to ask you to return mine 

for me, would you? 

CAPCOM Oh, you better believe it. They're listening 

to the squawk box. You don't have to say anything to me. And, 
over in El Lago, Jamie is saying her prayers ending them with "God 
bless America and Challenger" from now on. And, John is saying, 
"There's Daddy's rocket makes it go pitch light out." Of 
course, everybody sends their love — 

SC They're great. 

CAPCOM And, they're all listening right now if you'd -- 

SC Tell John, though, that I shaved the other 

ni ght . 

CAP COM Roger. He'll be listening, hearing that. 

They're all over at the -- in Nassau Bay at a big meeting of the 
flight plan. Where the Parkers are briefing the Cernans and the 
Evans on the flight plan tonight. And, out in Tucson, for the LMP , 
it's kind of cloudy and cold out there today. It's colder than nor- 
mal. Everything's working fine on the speaker out there, Jack, and they're 
just listening, and Mother -- your Mother is really tickled and 
just pleased as all get out. 

SC That sounds like Mother. And, I just got a 

real good view of Copernicus, but I'm afraid I can't help you out 
on that structure in the central peak. Just a little too dark. 


SC But, it's a fantastic sight at this altitude. 

There's a big crater. It looks like it's about 80 kilometers in 
diamete r . 

CAP COM I'll drink to that. 

SC And, put down a verify on those dark deposits 

in the wall. And, also on the southeast wall, there's one right 
on the rim. I think we mapped that one, too, but I'll have to 
go back and check. 


SC That one looked like it had a crater in it. 

However, they all tend to be elongate radially with respect with 
the crater. But, that's about all I can add now. 



COMMENTARY 12/10/72 GST 20:55 GET 96:02 MC360/2 

SC Bob, I'm glad the squawk box Is fixed, and, 

of course, send ray love and best wishes out there to Tucson. 

CAPCOM That's a roger, Jack. You guys might also 

be interested here in the Houston area. All of the ground voice -- 
or air-to-ground is being carried on FM station — 100 percent 
of it — and KUHT, the television station, will cover the — educa- 
tional TV station is going to cover 100 percent of the EVA's, all 
three of them for all the time. 

SC That sounds great. We hope we can provide 

them with as much education as we can entertainment. 

CAP COM We're counting on it. 

SC I guess Parker's all we have left down there 

to brief them on the landing site, huh? 

CAPCOM I won't even comment on that one. (Laughter) 

SC Okay. I figure he will later. 

SC I'd like, also, to send my best up north to 

the Bell — the Bellwood area up there, because I think there's 
a squawk box up there, too. 

CAP COM Beautiful. 

SC And, Bob, it's — all in all, it's been a 

pretty exciting day. I think a pretty accomplishing day, and 
certainly a rewarding day on our part. It's also been a long day, 
but we're hoping that it can only be superceded by tomorrow and 
judging from what we've got in store, it might very well be. 

CAP COM I think that sums up the day. It's a day of 

anticipation for what's going to happen tomorrow. Everything's 
gone off real well here, and we're just glad you're in the over- 
ture end and ready for tomorrow. 

SC My goodness, Bob. This is Jack. It's awful 

hard to spend much time up here anticipating. The events come so 
fast and, certainly, are exciting and rewarding, each one, one at 
a time. But, obviously, tomorrow is going to be the biggy. 

CAPCOM Roger. 

CAPCOM Ron, we're watching your 52 and just be ad- 

vised you do not have to do the Option 1. 

SC Okay. Real fine, Bob. 

SC Bob, I'm not sure whether it's entirely 

proper, being a bachelor, but I'd like to send my regards to 
everybody — all the families listening to squawk boxes tonight. 

CAP COM Roger. 

SC Bob, we're going right over the Procellarum 

Ridge now, if I'm not mistaken. Out in the middle of Mare 
Procellarum, and we're low enough now that you can see some of 
the te r r ai n . 


SC That is — that is, some of the hills, and 

rilles, and valleys associated with that ridge system.

CAPCOM Okay, there's not a whole lot of news on the 

wire tonight, as a matter of fact. President Nixon received a 
firsthand report on private Viet Nam peace negotiations today 
from a key member of the US negotiating team, 

General Alexander Haig, Jr., Henry Kissinger's Chief Lieutenant. 
Haig flew back from Paris to report to the President, while 
technical experts from both sides held and unusual Sunday meet- 
ing in the French capitol. Presidential Assistant Kissinger will 
resume his talks with North Viet Nam's Le Due To on Monday, after 
a one day recess. And former President Harry Truman continued 
to show some signs of improvement late today after he was earlier 
removed from the critical list at Research Hospital Hospital 
in Kansas City. His cardiac situation has improved and this 
improvement included a slower and stronger pulse and a stable 
blood pressure. The football scores are as follows in the 
National Footbal League today: the Bears defeated the Eagles 
21 to 12, the Detroit Lions and the Buffalo Bills played to a 
21-21 stand off, Dolphins extended their undefeated streak 23 
to 13 over the New York Giants, the Patriots defeated the 


the Central 
to 7, the 

New Orleans Saints 17 to 10, Green Bay sewed up 
Division of the NFC by defeating the Vikings 23

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 96:11 CST 21:05 MC361/2 

CAPCOM 49'ers defeated the Falcons 20 to nothing, 

20 to 0, and Pittsburg defeated Houston 9 to 3, and they took 
the Central Division of the AFC. So, the playoff picture is 
becoming a litte clearer. You've got, in the NFC you've got 
Washington, Dallas, and Green Bay, and the fourth team will either 
be San Francisco, Los Angeles, or Atlanta. That will be decided 
next week. In the AFC Pittsburg, Miami, and Oakland are in it, 
and the fourth team will be either the Jets and another team. 
They've got the Giants listed here, but it can't be the Giants, 
because that's the wrong division. So we'll check that one out. 
Cleveland, okay, Cleveland. The fourth team is either going to 
be Cleveland or the Jets. And did you get a spurious as master 
caution warning.

it? In either case the times are a little bit long on 
extend retract which is a little cause for worry about that 
mapping camera may fail and later on downstream we may want 
to change our operating mode on that mapping camera and he 
might want to time a little closer. If he can get the chances 
it could come up. 

SC Bob, that's a good point on the thing, 

those weren' t quoted exact times and matter of fact we kinda looki 
away and it was about a ... you know, somewhere about 
that period, of time. We looked away and when we looked back 
it was gray again. Next time we extend them I'll get a good 
accurate indication. 

CAPCOM Okay, no problem. We'll believe the strip 

ch ar t. 

CAPCOM We'll take the strip chart data. We've 

got 1 24, 1 minute 24 seconds for extend and 1 51, 1 minute 
51 seconds for retract. And both those are a little bit 
on the high side. 

SC Okay. I would believe the strip chart. 

CAPCOM R°g» Ron, you all are about 4 minutes 

from LOS. Okay, we might loose you a little bit earlier 
th an that. 

CAP COM Okay, we may loose you a little early 

due to the SIM bay attitude and will pick you up at 97:22. 

SC Okay, Bob. Once more around at 9 7:22. 

PAO This is Apollo Control at 96 hours 

34 minutes. Apollo 17 has turned the corner a little 
early, about 50 seconds early. We've lost contact with the 
antenna because of it's attitude, about 50 seconds early. 
During this 4th pass on the front side of the Moon there 
was considerable description of the Lunar surface and photog- 
raphy was accomplished. The mapping camera experts will 
continue to study the extension and retraction times of the 
camera. If those times continue to grow, they will probably 
revise the flight plan somewhat to reduce the number of times 
that camera must be extended and retracted. At the present 
time though they are just keeping a close eye on those times 
to see whether they will continue to grow. We'll next acquire 
Apollo 17 on it's 5th revolution of the Moon at 97 hours 
22 minutes.

PAO We have a signal nov. 

SC Houston, 17. 

CAPCOM 17, Houston, go ahead. 

sc Roger, we're just about ready to finish 

up here. I have a couple of questions. Do you want us to 
cycle cryo fans or just leave them alone now? 

CAP COM We'd like them just left alone, left in 

your configuration you are now, Jack. 

SC Okay, there will be no cyclying then. 

CAP COM Roger, we have one question. Whose got 

the duty tonight or will he be wearing a headset. 

sc Yes, Ron has the duty he will be wearing 

the headset, but I will be on the biomed underneath. 

CAP COM Understand that, and one note for Gene. 

It's an addtiion to that flight surgeons note. When you 
rehydrate your food make sure that you go the - let it re- 
hydrate for the maximum amount of time. I know you miss it 
on this one, but the next - like tomorrow morning make sure 
it rehydrates the maximum amount of time. 

SC Okay, I'll tell him. 

CAPCOM Roger. 

2C And we've got the star crater stereo trio. 

CAPCOM Roger. 

Sc And we're mag oscar oscar is on 93 now. 

The last three pictures were that trio. 

PAO This is Apollo control at 97 hours 

28 minutes. We're showing - 

SC We're sensing complete on the presleep 

checklist. And except for computing agents configuration and 
Ron will take care of that. 

CAP COM Roger. 

SC And, Bob while we're gradually getting 

into configuration here let me reiterate something that I've 
been watching this rev as we did a lot of other things. And 
that was this relationship of the light colored or light gray 
swirl patterns on the surface to patterns associated pattern 
parallel patterns that are darker than the average of the 
surrounding area. And this is true both in Mare Marginus 
and in most cases on the back side. 

CAPCOM Roger, Jack, we'll get that to the Pis. 

SC Roughly, although their very irregular 

patterns roughly it's concentric zoning of dark to light 

APOLLO 17 MISSION COMMENTARY 12/10/72 CST 22:15 GET 97:21 364/2 

SC within an intermediate albedo surface. 

Now there are variations on that theme sometimes you don't 
get the symmetry quite as good, but it's common enough that I 
think it's worth noting. 

CAPCOM Roger. 


APOLLO 17 MISSION COMMENTARY 12/10/72 22:24 CST 9 7:30 GET 365/1 

SC Also, there's a sequence, different kinds 

of crater filling on the far side, and I think that as the orbit 
stay progresses, we may be able to pin down the relative age 
relationships and the characteristics of those crater fill - 
filling episodes. Whether they are single episodes that 
happen in a variety of craters or they're a function of the 
age and characteristics of the craters in which you find 
them is not clear right now, but the - they seem to form 
fairly distinct groupings of crater fill material. 

CAPCOM Roger, Jack. 

SC One of those crater fill materials that 

you also see in other kinds of depressions other than craters 
is a very smooth light plains forming material and it is 
although cratered when you see it at the terminator, it is 
smoother than the Mare. That is, it does not seem to have 
the swell, the sea swell characteristics or ridges or any 
other features other than the craters superimposed on it. 

CAPCOM Roger. We copy. 

PAO Apollo 17's orbit now 59.2 by 13.7 nautical

APOLLO 17 MISSION COMMENTARY 12/10/72 GET 97:48 CST 22:41 MC367/1 

PAO This is Apollo Control. We said goodnight 

at 97 hours 47 minutes. We'll leave the line up for a few minutes 
longer, to see whether there's any further conversation. 

PAO This is Apollo Control at 97 hours 53 minutes. 

Crew has just turned off the voice switch on the spacecraft, 
indicating they do not intend to talk anymore tonight, and 
we do not intend to put in anymore calls to them, so we'll take 
this line down now and come back up with hourly reports, during 
the sleep period, which has just started. 


APOLLO 17 MISSION COMMENTARY 12/10/72 CST 23:45 GET 98:52 MC 368/1 

PAG) This is Apollo control at 98 hours 52 minutes. 

Flight Director, Pete Frank and members of the Orange Team, are 
preparing to hand over flight control duties to Flight Director, 
Gene Kranz and the White Team at this time. There will be no 
change of shift news conference. Shortly after the Orange Team 
came on duty, the descent orbit insertion number 1 maneuver was 
performed. At 93 hours 11 minutes 36 seconds, this was a very 
good burn. Duration 22 seconds. Velocity change of 198.2 feet 
per second. Resultant orbit was 59.1 by 14.9 nautical miles. 
Apollo 17 crew since that time has been performing landmark 
tracking through the sextant, a great deal of photography, and 
performing the ultraviolet spectrometer and infrared scanning 
radiometer experiments, and providing surface descriptions, the 
geology reports and some Earth weather reports from lunar orbit. 
The infrared experiment will be continued throughout the rest 
period that the crew is now in. The ultraviolet experiment has 
been terminated for tonight. The mapping camera is taking longer 
to extend and retract than expected. And the last operation took 
1 minute 24 seconds to extend and 1 minute 51 seconds to retract. 
Each of these operations should be accomplished in 1 minute 
12 seconds. The camera experts will continue to watch this and 
if the delayed operation continues, they may reduce the number of 
times that the camera is extended and retracted. Crew said 
goodnight at 97 hours 47 minutes. They're anticipating a big 
day tomorrow, landing, first EVA. 7 hours 49 minutes remaining 
in that rest period. Apollo 17 f s present orbit is 59.1 by 13.5 
nautical miles. And a short time ago the flight dynamics officer 
gave the flight director the latest impact coordinates for the 
S-IVB which impacted the lunar surface today at 89 hours 39 minutes 
40 seconds. Coordinates for that impact; 4.21 degrees south latitude 
12.31 degrees west longitude. At 98 hours 55 minutes this is 
mission control Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 GET 99:16 CST 0009 MC 369/1 

PAO This is Apollo Control at 99 hours 16 minutes. 

We are about 1 minute from reacquiring Apollo 17 now in its 6th revolu- 
tion of the Moon. We said goodnight to the crew on the last 
revolution at 97 hours 47 minutes and the flight surgeon reported 
that it appeared Jack and Ron were both dozing off before we 
lost radio contact with the spacecraft as it went around behind 
the Moon on the fifth revolution. Here in Mission Control, 
flight director Gene Kranz has been reviewing the status of the 
mission with his oncoming team of flight controllers. No pro- 
blems of note to be reported. The service propulsion system 
engine, it was reported, looks to be in very good shape as a 
result of the, or based on the data received during the LOI and 
DOI, the lunar orbit insertion and descent orbit insertion 
maneuvers performed earlier. The flight dynamics officer, during 
this shift, is going to be following the spacecraft trajectorys 
very closely looking for any cross range or down range errors 
which would need to be compensated for prior to the lunar landing. 
We don't expect any conversations with the crew. We have had 
confirmation of acquisition of signal now and we'll stand by for 
a short period of time to get a look at the systems and to assure 
that we're not going to get a call from the crew. This is 
Apollo Control. No sign of any activity from the crew. The 
flight surgeon reports that Jack Schmitt and Ron Evans, both of 
whom are wearing their biomedical sensors during the sleep period, 
appear to be sleeping soundly at this time. Apollo 17 is current- 
ly in an orbit 59.1 by 13.5 nautical miles and we have about 
52 minutes remaining before the spacecraft again goes behind the 
Moon and we lose radio contact. We'll come up with a status re- 
port shortly prior to loss of signal. At 99 hours 31 minutes 
this is Apollo Control Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 01:15 GET 100:22 MC 

PAO This is Apollo Control at 100 hours 22 

minutes. Apollo 17 has now gone behind the Moon and before 
we lost radio contact the Surgeon reported the crew appeared 
to be sleeping soundly. We have about 6 hours 22 minutes 
remaining in this sleep period before the crew awakens to 
a very busy day which will include landing on the Moon for 
the Lunar Module Crew, Jack Schmitt and Gene Ce rn an and the 
first Lunar Surface EVA. Shortly before loosing radio 
contact Gene Crans checked with each of his flight controllers 
got a report that everything was in order, no problems as 
Apollo 17 went behind the Moon. We'll be reacquiring the 
spacecraft in its seventh revolution in a little less than 
45 minutes. At 100 hours 23 minutes this is Apollo Control, 
H ous t on . 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 02L03 GET 101:10 MC 371/1 

PAO This is Apollo Control at 101 hours 10 

minutes and we are standing by now to re-establish radio 
contact with Apollo 17 at the beginning of it's seventh 
revolution of the Moon. We anticipate the crew will be 
sleeping soundly as they were when we last had radio contact 
with the spacecraft some 45 minutes ago. Infact, the 2 
crewmen on whom we have biomedical data, Ron Evans and Jack 
Schmitt, appeared to have gone to sleep almost as soon as 
they said goodnight. Very shortly thereafter the surgeon 
noted the slow down in heart rhythms thypical of sleep. 
And that is the condition they were in when we last saw 
them at the end of the sixth revolution. And we have 
reacquired radio contact with Apollo 17 and getting good 
data from the spacecraft at this time. The crew is scheduled 
to end this 8 hour rest period in a little over 4 and one 
half hours from now. And it appears that everything is 
quiet aboard Apollo 17 and no signs of any crew activity. 
We will take the lines down and continue to monitor and 
we'll come up with another status report just prior to 
loss of signal as the spacecraft goes behind the Moon on 
this the seventh revolution. This is Apollo Control at 101 
hours 12 minutes.

quietly here at Mission Control. We now have three and 
one half hours until the scheduled crew awakening time. 
And we've just loss of signal from Apollo 17, now going 
behind the Moon on it's seventh revolution. We'll be 
reacquiring in about 40 minutes. At the present time we 
show Apollo 17 in an orbit roughly 59 by 13 nautical miles. 
And it appears that the crew is continuing to get good 
sound sleep with three and a half hours, as we said, 
remaining in the sleep period. At 102 hours 18 minutes, 
this is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 03:56 GET 103:03 MC 373/1 

PAO This is Apollo Control at 103 hours 4 

minutes. We're standing by now to re-establish radio contact 
with Apollo 17 as the spacecraft comes around the eastern 
rim of the Moon and reappears on the front side in it's 
eighth revolution of the Moon. The crew now, a little more 
than 5 hours into their sleep period, about 2 hours 40 minutes 
remaining before we send them the wakeup call. And all 
spacecraft systems continue to perform normally. No out- 
standing problems at this time. We are showing Apollo 17 in 
an orbit of about 59 by 13 nautical miles, and we should be 
seeing telemetry data shortly now. Radio from the spacecraft 
being received at the 210 foot dish antenna at Honeysuckle 
Creek, Australia, near Canberra. And we're once again re- 
ceiving data from the spacecraft. We, of course, do not expect 
any activity from the crew and we'll have the lines down 
during this front side pass, should there be any unexpected 
conversations we'll bring up the lines immediately. We'll 
have about 1 hour and 5 minutes before Apollo 17 disappears 
around the back side of the Moon on the eighth revolution. 
This is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 05:03 GET 104:10 MC 374/1 

PAO This is Apollo Control at 104 hours 10 

minutes. Apollo 17 has just gone behind the Moon now. The 
spacecraft on it's eighth revolution of the Moon and we'll 
be reacquiring in about 45 minutes as Apollo 17 comes back 
around the eastern rim of the Moon on it's nineth revolution. 
During the nineth revolution we'll be sending the wakeup 
call to the crew, getting them ready for one of their 
busiest days on the mission which will include LM seperation 
from the Command Module and the powered desent to the lunar 
surface followed by the first period of lunar surface 
exploration in the valley of the Taurus Mountains. The 
flight surgeon reports the crew has been getting, apparently, 
a very good nights sleep. They are now six and one half 
hours into that scheduled 8 hours sleep period with about 
an hour and one half of sleep remaining. Apollo 17 in an 
orbit 59 by 13 nautical miles and if every thing goes 
according to the flight plan undocking will occur about 11:20 
Central Standard Time on the twelveth revelotion with powered 
descent to the lunar surface coming at about 1:55 P. M. 
At 104 hours 12 minutes this is Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 05:50 GET 104:57 MC 375/1 

PAO This is Apollo Control at 104 hours 58 

minutes and we're standing by to reacquire radio contact 
with Apollo 17 spacecraft now in it's nineth revolution of 
the Moon and will shortly be coming around the eastern 
rim of the Moon and back out on the front side. During 
this front side pass CAPCOM, Joe Allen, will be putting in 
a call to the crew getting them up and started on a very 
active day which will include landing on the lunar surface 
in a valley of the Taurus Mountains near the Sea of Serenity. 
Our last look at the spacecraft's lunar orbit showed it to 
be maintaining an orbit fairly close to 13 nautical miles 
by 59 nautical miles, actually dropping down somewhat below 13 
on the pericynthion to about 12 point 6. And we should have 
radio contact with the spacecraft shortly and we'll begin 
getting telemetry data on all of the spacecraft systems. 
We have 46 minutes showing until scheduled crew wakeup 
time. And we've had the AOS call, acquisition of a signal, 
getting good high bit rate data at this time. And the 
flight dynamics officer's orbit display shows Apollo 17 to 
be in an orbit of a high point of 59 point 9 nautical miles. 
The low point or pericynthion of 12 point 5. We'll come 
back up a few minutes before the scheduled crew awakening 
time, about 45 minutes from now, and follow live from that 
point on as the crew begins preparations for LM activation, 
seperation and the landing on the lunar surface. This is 
Apollo Control, Houston. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 06:33 GET 105:40 MC 376/1 

PAO This is Apollo Control at 105 hours 40 

minutes. We're about 5 minutes away, now, from putting in 
a call to the crew getting them up for breakfast and ready to 
start a day that will culminate with landing on the lunar surface 
and the first EVA at the Taurus Mountain site, Taurus Littrow, 
near the Sea of Serenity. CAPC0M, Joe Allen, will be putting 
in a call to the crew in about four and one half minutes 
from now and we'll stand by for that wake up call to the 
crew of Apollo 17. Here in the control center the landing 
shift, landing team of flight controllers, is beginning to 
come on duty, after a very quiet uneventful night monitoring 
Apollo 17 in lunar orbit. The spacecraft now on it's nineth 
revolution of the Moon completing the front side pass and 
we'll be losing contact with the command module as it goes 
behind the Moon on the nineth revolution in about 22 minutes.

SC Righto Joe. 

PAC This is Apollo Control. We've now had loss 

of signal as Apollo 17 goes behind the Moon on the ninth revolu- 
tion. We'll be reacquiring in about 45 minutes - a little bit 
less, as the spacecraft comes back on the front side on the 
tenth revolution. And by that time the crew should have completed 
breakfast. They'll be getting the pressure suit unstowed and 
begin preparations for entering the lunar module, for the separation 
landing on the lunar surface, and the first EVA all scheduled to 
occur this day. The IR data which Joe Allen advised the crew 
we're getting in such good form back here on the ground from the 
spacecraft's service module, is from the IR scanning radiometer. 
This is an instrument carried in the CSM SIM bay, scientific 
instrument module bay. And it's obtaining surface temperatures 
under the groundtrack of the spacecraft from which scientist will 
be able to construct a temperature map. From this information 
they hope to be able to characterize such lunar surface physical 
parameters as the general conductivity, the bulk density and 
the specific heat. Apollo 17 at the present time is in an orbit 
about 59 nautical miles at it's high point and about 12 and 
a half miles above the lunar surface at the low point. At 106 hours 
5 minutes this is Apollo Control Houston. 


APOLLO 17 MISSION CONTROL 12/11/72 07:43 CST 106:51 GET MC379/1 

PAO This is Apollo Control at 106 hours 

51 minutes. We're about 2 minutes now from reacquiring 
Apollo 17 as the spacecraft comes back around on the front 
side of the Moon on the tenth revolution. 

And when we again establish radio contact the crew should 
have pretty well finished breakfast and be getting suited 
up ready for Jack S chmi 1 1 and Gene Cernan to enter the 
lunar module and begin preparations for separation, powered 
descent to the lun.T.r surface. Here in the control center 
we're in the process of a shift handover. Flight director, 
Gerry Griffin, and the team of flight controllers who will 
be on during today's powered descent are now coming on to 
replace the Gene Kranz team. Flight director Neil Hutchinson 
will be in charge of CSM activities once the two vehicles 
separate. CAPCOM for the lunar module will be Astronaut

of good sleep; a little trouble getting to sleep last night and I 
woke up early this morning. I took a Seconal, didn't seem to 
have much good - much effect, and had 4 cans of water. 

CAP COM Roger. 

SC I think I was on the biomed all the time 

last night too, so you can check out that sleep. 

CAP COM Okay, Ron, while you've got that book with 

you, I can give you a one-line change to the E memory load as 
a result of our changing the short burn constant. 

SC Okay, stand by one there. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST 08:24 GET 107:30 MC-383/1 

SC Okay, Houston America. I've got the right 
page n ow . 

CAPCOM Okay, it's page 1-43. It's load DELTA. 

Identifier #5 the old value is 01606, change that to 01637. 

SC Okay. Be load DELTA and the octal 

identifier 05 and it's new value is 01637. 

CAP COM That's correct. 

SC Okay. The LMP has got his suit on. They're 

connecting up the LCG water connection. And he's still unzipped. 

CAPCOM Okay, Ron. In the flight plan you're coming 
up on a VERB 45 and then go into POO prior to the P52. After 

going to POO we'd like you to change to BD roll from AC. Over. 

SC Okay, we'll change the BD roll. Looks like 
we're going to run into a problem on our P52 down here, with 
these guys getting suited. Is it really necessary now? 

CAPCOM There's no time criticality on that. When 
they're out of the way, go ahead with it. 

SC Okay. Good. 

SC Okay, Houston. How do you read the LMP? 

CAP COM LMP is loud and clear. 

SC Okay, Gordy I'm opening the hatch. 

CAP COM Okay. 

SC And the light's still on. 


SC Okay, Gordy, index 1 plus - or plus 1.2. 

CAPCOM Roger. 

SC Okay. 

SC Okay, Houston I'm going to forget the P52 for 
a while and maneuver to the docking attitude. 

SC Undock attitude that is. 

CAPCOM Roger. 

CAPCOM Stand by on that one Ron. 

SC Wilco 

CAPCOM We want to be sure we can get some stars - 

good stars in the undock attitude. 

APOLLO 17 MISSION COMMENTARY 12/11/72 08:39 CST 107:46 GET MC384/1 

CAPCOM Ron, this is Houston. We didn't see you 

do a VERB 45. Over. 

SC You're right. Here's one. 

CAPCOM And if there's any - if there's no reason 

why not, we'd just as soon you go ahead and do the P52 now. 
Finish that off and then start the maneuver. Over. 

SC Okay. The big reason is that Gene's getting 

into his suit right now. 


SC As soon as he gets out and gets in his 

suit we'll all do a P52 maneuver. 

CAPCOM Ron, Houston. Can you give us AUTO on 

the high-gain? 

SC Okay. Just a second Houston. 

SC We're transferring to LM power, Houston. 

SC Okay, OFF, read that. Back to OFF. Okay, 

we have LM power. 

SC Okay, that was 107:49:28. 

CAPCOM Roger. 

SC LM water is open; 02 is open. 

CAP COM Roger. 

SC Okay, 3-4, Houston, in the LM and step 


CAP COM Okay. 

SC Okay, step 2 is complete. 

CAPCOM Okay, Jack. 

SC And I'm going off of CSM COMM and I'll 

be coming at you before long on S-band if I can. 
CAP COM Okay. 


APOLLO 17 MISSION COMMENTARY 12/11/72 08:47 CST 107:54 GET MC-385/1 

CAPCOM Ron, Houston; we've taken a look at stars 

available in the undock attitude and they don't look too good. 
We suggest you use the present attitude for your 52 and then 
maneuver. Over, 

SC Okay, I'm just about to get Gene out of the 

way here and then I will. 

CAPCOM Okay, and we're less than 3 minutes to LOS 

now, so when you finish that 52 we'd like you to copy down the 
NOUN 5 and 93's for us. 

SC Okay, will do. 

CAPCOM America, Houston, about 1 minute to LOS. 

Nothing further you, we'll see you on the other side. 

SC Okay, Gordo, we're hustling like hell, we 

mi gh t make i t . 

CAP COM Roger. 

PAO This is Apollo Control at 107:59 ground elapsed 

time into the mission of Apollo 17. We've had loss of signal at 
this time as Apollo 17 coasted behind the Moon on the tenth lunar 
orbit. Approximately 47 minutes until the spacecraft both come 
around the far side as the crew prepares to transfer into the 
lunar module; that is, Cernan and Schmitt prepare to transfer into 
the lunar module. Get it powered up in preparation for today's 
activities of the descent orbit insertion maneuver number 2 and 
ultimately the landing at Taurus-Littrow and the first extravehicular 
activity. As they come around the Moon on the eleventh revolution, 
they will have checked out the lunar module with a few exceptions 
such as they will deploy the landing gear after acquistion of 
signal. Also at that time, both spacecraft, Challenger and America, 
though still docked, will be on separate air to ground links. The 
lunar module will be on the normal channel; the command service 
module link, with Ron Evans, will be piped into Room 161 in the 
News Center building for those newsmen covering the mission who 
prefer to listen to the command service module orbital science 
activities. As Apollo 17 went behind the western limb of the Moon, 
the orbit measured 12 nautical miles at pericynthion and 60.2 at 
apocynthion. Some maneuvers coming up - the next major maneuver 
for the lunar module will be the descent orbit insertion number 2 
which at this time is predicted, or is calculated to take place 
at a ground elapsed time of 112 hours 1 minute 59.1 seconds. Total 
burn time of 21.8 seconds. For a Delta V or velocity change of 
7.6 feet per second, which will change the orbit to an apocynthion 
of 60.4 nautical miles and a pericynthion, or nearest approach, 
which is just uprange of the landing site, of 6.7 nautical miles. 

APOLLO 17 MISSION COMMENTARY 12711/72 08:47 CST 107:54 GET MC-385/2 

PA0 The big maneuver of the day, of course, is 

powered descent and landing, which at this time is calculated to 
take place at a ground elapsed time of 112 hours 49 minutes 
27 seconds, lasting 11 minutes and 57 seconds, plus whatever 
hover time is available as they get down to the landing site. 
Total Delta V, or velocity change, to get out of orbit and break 
into the descent pass and ultimately the hovering and touchdown 
at Taurus-Littrow is 6693 feet per second. Some 43 minutes now 
away from acquisition as Apollo 17, America and Challenger, come 
from behind the Moon on orbit number 11. And at 108:04 ground 
elapsed time, this is Apollo Control. 


APOLLO 17 MISSION COMMENTARY 12/11/72 CST9:38 GET108:45 386/1 

PAO This is Apollo Control at 108 hours 

44 minutes ground elapsed time. Less than 2 minutes away 
from acquisition as America and Challenger, the spacecraft 
of Apollo 17, come around from behind the Moon on lunar orbit 
number 11. At that time the voice downlinks from both space- 
crafts will be separated. For those, newsmen in Houston, who 
wish to listen to the voice from Ron Evans in the command 
service module, this will be available in room 161 in the 
Newscenter Office Wing. At the time the spacecraft reap- 
pears from behind the Moon, the crew should have completed 
most of the lunar module checkout procedures, and be pre- 
pared for deploying the landing gear, and a series of com- 
munication checks with the ground. Just before loss of sig- 
nal on the eleventh revolution, the crew will be given a 
GO NO-GO for undocking and separation, which will take place 
during the time when the spacecraft is behind the Moon near 
the end of revolution number 11. In other words, when they 
reappear again, they will be flying separately on the twelfth 
revolution. We should have acquisition any moment, now, 
we've counted down to zero on the acquisition of signal 
clocki here in the Control Center. It takes a few seconds 
for the ground to lock up solidly with the downlink signal 
with the spacecraft. Network reports acquisition of signal, 
let's bring up the line and listen for the first call. 

CHALLENGER Th ere we go, we should have done that 

in the first place.

We've had LOS of 

and Challenger pass behind the Moon on the - 
the 11th Lunar Orbit. When they reappear again 
approximately 47 minutes, they will be undocked. Station keeping 
flying along adjacent to each other. At LOS of signal the 
orbit measured 61.2 nautical miles pericynthion by 12 miles even 
nautical - pericynthion. Velocity at that time was 5315 feet 
per second. During the next front-side pass, as the Challenger 
continues in preparations for the descent orbit insertion we'll 
have a checkout of the descent propulsion system. The tanks 
will be pressurized and telemetry readouts here on the ground 
will be prepared to those on board, to make sure that, that 
system is preforming as advertised. An alignment - realignment 
of the inertial measuring unit, part of the lunar module's 
guidance system will be run during that -- also during that front- 
side pass. And toward the end of the 12th revolution, just 
prior to LOS of signal the crew aboard Challanger will be given 
a GO/NO-GO for the Descent Orbit Insertion Maneuver #2, which is 
at this time still scheduled for a ground elapsed time of 112 hours 
1 minute 59 seconds. There's a carton of book matches on top of 
the flight director-console here in the Control Center which 
was bought by a group of flight dynamics officers on all the 
ships. Bill Boone, Jay Green, Jerry Bostick and others. It's 
a blue match cover, it says The Trench. Traditionally the trench 
is the front row here in the Control Center where the flight 
dynamics people operate. It says on the front The Trench, Mission 
Control Center, Houston. On the reverse of the match book it 
says Mercury, Gemini, Apollo, Skylab, Apollo Soyu2 Test Program 
Shuttle. Mercury, Gemini and Apollo have a check by them

Less than 2 minutes remaining now until America and Challenger 
separated and flying a few feet apart at this time will come 
around the front side of the Moon on the 12th lunar orbit. Slightly 
over a minute now until we should start attempting to lock up on 
the downlink signal f rom America and Challenger. The two way 
communications from spacecraft communicator for the command-service 
module, Ken Mattingly, and Ron Evans aboard America will be on a 
separate loop as it was the last revolution. These conversations 
can be heard in room 161 in the Houston News Center. Early in this 
revolution we'll have the p re s s uri z ati on of the descent propulsion 
system and checkout of that system. Some 6-5 seconds from acquisi- 
tion we'll stand by until Network advises the Flight Director that 
they do have firm lock on. We have AOS in lunar module, let's see

CAP COM That's right. 

CHALLENGER Gordo, this is spectacular. It is absolutely 

spectacular looking at that command module, America down there 
coming across the surface. We're just tracking them at about a 
30 degree dive angle. 

CAPCOM Sounds great. 

CHALLENGER Okay, babe, have a good time, and go get that 

landmark. Don't forget TEIC in about 3 days. 

CAPCOM Geno, Houston with a couple of items.

CHALLENGER Hey, we got the landing site Gordo. 

CAPCOM Okay, I'll hold -

right over the front of it; stand by a minute, you can see the

across it.

CHALLENGER Super targeting. God, we've got Family 

Mountain, we've got Corsa Massif; we can see the Scarp, we can 
see the light mantle; I've got the Great Cross, Camelot, Sherlock,

CAP COM How about that. 

CHALLENGER I see possible structure - possible structure 

in the upper part of the South Massif, little bit east of station 
It's some horizontal, dipping to the southeast. Houston, I can 
even see Poppy, right where we're going to set this baby down. 

CAPCOM Very good. 

CHALLENGER As a matter of fact, I can see Rudolph. I 

can even see the triangle: Rudolph, Frosty and Punk. 

CHALLENGER Man, Gordo, this is absolutely spectacular. 

CAPCOM Sure sounds like it. 

CHALLENGER We can watch Ron track - we can watch Ron 

track right on through the landmarks, I don't what kind of re- 
sults he got, but he had a nice smooth track from here. 

CAP COM Roger. 

CHALLENGER Gordo, you can go ahead and update us with 

those words. 

CAPCOM Okay, your perilune is shifting west PDI will 

be a little higher than nominal: 10.7 miles or 65 000 feet; 
should be no problem. And from the time you first came around 
till we had a solid lock up on the steerable on this acquisition 
was about 3 minutes, we're going to try to speed that up some 
on the next time around. We'd like you to just keep trying the 
steerable until we come to you - and say stop trying. Over.
