GEMINI 9-A/MISSION COMMENTARY 6/3/66, 3:35 a.m. Tape 1 ,~ Page 1 

This is Gemini Launch Control. T-2U0 minutes and counting. H-2k0 and counting 
on the Gemini 9-A mission. At this point in the countdown, the Gemini Launch 
Vehicle has just joined the countdown. The spacecraft of the Gemini ...space- 
craft started about 2:30 a.m. this morning, that is 2:30 EST at the 360 minute 
mark in the count. So, we now have the launch vehicle in, all the major elements 
are in the count at this point and all is going very well. 

The Gemini Launch Vehicle was fueled last night in an operation that took 
about three hours and 15 minutes. Since the spacecraft count was picked up earlier 
this morning, all is going well. 

The backup pilots for the mission, Astronauts Jim Lovell and Buzz Aldrin are 
aboard the Gemini Spacecraft making their checks. They have been in there for about 
two and a half hours at this time. They will continue all the preliminary checks 
pending the arrival of the prime pilots, Tom Stafford and Gene Cernan, later in the 
jountdown. Stafford and Cernan should be up at this time and taking their physical 
and probably about to start breakfast. We will have a report on that as soon as 
we get that information on it. All going well now at T-238 minutes, ^3 seconds 
and counting. This is Gemini Launch Control.

going well in the Gemini 9 countdown at this time. We now have 
confirmation that the prime pilots for the mission, Tom 
Stafford and Gene Cernan were awakened in their Crew Quarters 
at the NASA Kennedy Space Center, Merritt Island, as planned 
in the astronaut countdown at 11 minutes passed the hour. They 
are just completing their physical examination at this time and 
will be sitting down to breakfast in about 5 minutes, or so. 
All going well with the astronauts in the Crew Quarters and with 
the countdown at Launch Complex 19 . This is Gemini Launch Control.

This is Gemini Launch Control. T-208 minutes and counting. 208 and counting 
and all is going very well at Launch Complex 19 at the present time. The prime 
pilots for the Gemini 9-a mission, Astronauts Tom Stafford and Gene Cernan, are 
just about finishing up their breakfast at this time. They have one guest for 
breakfast at the Crew Quarters at the NASA Kennedy Space Center in Merritt Island, 
and that is .Donald K. Slayton, who is Director of Flight Crew Operations for 

the NASA's Manned Spacecraft Center. 

Stafford and Cernan took their brief physical again a short while ago. Doctor 
Duane Catterson, who directed the physical, reported that there is no change in the 
statue of either of the astronauts physically since their last physical two days ago. 
Both pilots were described as being in excellent spirits, as usual. 

We have some weather conditions, which we'll go over extensively at this point, 
to cover the Cape area and the various contin 'gen'oy landing areas throughout the ground 
track. The weather forecast for launch time in the Cape Kennedy area is as follows: 
Scattered clouds, at about 3000 feet, winds from the northeast at 15 knots, a sea 
state off shore at four feet and a temperature expected to be about 75 degrees. In 
the AtiaxttSic, we have acceptable landing conditions throughout, however, if we launch 
during the first window, we will overfly t a rather extensive area of showers in the 
western Atlantic. If we launch in the second window, we will fly the west Atlantic 
showers as well as the shower area just north of the equator. In the mid-Pacific 
some 300 miles northeast of Honolulu, the forecast is for scattered clouds, winds 
from the east at 15 knots, a sea state of five feet. Western Pacific landing zone. 
About 700 miles southeast of Toyko, overcast sky with opeeasional rain, winds from 

the southwest, 12 knots, a sea state of four to five feet. In the eastern Atlantic 
landing zone, some5©0 miles west of the Cape Brady Islands, the forecast is for 
scattered to broken clouds, winds from the northeast at 12 knots, wea state of four 
feet. And in the prime landing in the west Atlantic, some 500 miles east of Miami 
also a forecast of scattered clouds, winds from the southeast 15 knots. All proceeding

and counting, and all proceeding excellently in the Gemini 9 
countdown at this time. At Launch Complex 19 things are going 
well with both the Gemini spacecraft and the launch vehicle since 
the count began some 2 hours and kO minutes ago. The back-up 
pilots for the mission, astronauts Jim Lovell and Buzz Aldrin 
have left the Gemini spacecraft, they have been in there for about 
2=? to 3 hours and they will be back a little later in the count 
to make the final dieck and report to the prime pilots, Tom Stafford 
and Gene Cernan at the white room. Stafford and Cernan as reported 
eariler were awakened at the planned time in the countdown for 
11:00 a.m. Eastern Standard Time. They've taken their physical 
and are just about finishing up breakfast at this time. They're 
due to depart their quarters at the NASA Kennedy Space Center 
at Merritt Island at 21 minutes past the hour, to proceed to the 
ready room to don their suits and make the final preparations 
for the mission. All going well in the count and all going well

This is Gemini Launch Control at T-19^ minutes and counting. 
T-19** all proceeding very satisfactorily with our checks at com- 
plex 19, with the Gemini spacecraft and launch vehicle. Astronauts 
Tom Stafford and Gene Cernan should be just about on their way 
now from the Crew Quarters at the NASA Kennedy Space Center Merritt 
Island, and starting the drive of some 7 miles to the ready 
room at Launch Complex l6 where they will don their space suits 
and make their final checks prior to departing for the launch 
pad at about 125 minute mark in the countdown, Their back-up 
pilots Jim Lovell and Buzz Aldrin have left the Gemini spacecraft 
they have been in it for some 2 hours and U5 minutes. As we 
prepare for the pressurization of the launch vehicle at 19, the 
complete area has to be evacuated at the time of pressurization 
of the launch vehicle, which is when we pressurize with the 
nitrogen at about 170 minutes into the count. Lovell and Aldrin 
will return to the spacecraft when the area is clear to make the 
final checks, and then they'll be ready to report to the prime 
pilots when they arrive at the white room. Our count with the 
Gemini Launch Vehicle also going very well, it was fueled in 
about 3 hours and 15 minutes last evening. Now, T-192 minutes 
and 35 seconds and counting. This is Gemini Launch Control, 
we'll now switch to the Mission Control Center in Houston.

very well at this time. Astronauts Tom Stafford and Gene Cernan should be just 
about arriving at this point at the Ready-room at Launch Complex 16. They have 
cleared the White-room at the 109 foot level at Launch Complex 19 in preparation 
for the launch vehicle pressurization , which will be coming up in about 10 or 15 
minutes from this time. 

Above the spacecraft in the White-room, just above the hatches, located just 
between the two hatches so that it covers both of them if you will, there is a sign 
located above the hatches. The sign has two little rhyming; couplets on it and it 
reads as follows, " WE WERE KIDDING BEFORE , BUT NOT ANYMORE. GET YOURSELF INTO SPACE 
OR WE'LL TAKE YOUR PLACE." And it is signed Jim and Buzz, of course for backup pilots 
Jim Lovell and Buzz Aldrin. All is proceeding vefy well at this point as far as the 
Gemini Launch Vehicle is concerned. We've just made some checks on the radio command 
guidance system, these checks appear to be going well.

This is Gemini Launch Control. T-17^ minutes and counting -- T-17^. All 
going very well at this time at Complex 19. We'll be coming up on our 
launch vehicle pressurization some five or ten minutes from this time. 
This is when we pressurize the propellant tanks in the Gemini launch 
vehicle -- both stages -- with nitrogen building up to some 30 pounds 
per square inch in the first stage and about 50 to 55 pounds per square 
inch in stage number two. We have made one slight .jump in the countdown, 
if you will. We're -- an event scheduled for the 60-minute mark in the 
count is occurring at this time. This is the so-called POGO activity 
in which we permit the oxidizer in the second stage to flow into a stand 
pipe -- a stand pipe that's specially built in the second stage area -- 
in order to suppress oscillations that could occur in the oxidizer system 
of the second stage. This usually romes at the 60-minute mark in the 
count. This is when we would open the prevalve — the oxidizer prevalve — 
to permit the flow of that nitrogen tetroxide oxidizer into the stand pipe 
area so that we will be able to suppress these oscillations ; since the 
prevalves were opened on Wednesday's launch attempt and since they are 
still open at this time, the crew decided to go ahead with this particular 
test earlier, and it is in progress now. Astronauts Tom Stafford and 
Gene Cernan are at the ready room making their final preparations. They'll 
come to the pad some 30 minutes from this time. T-172 minutes, ik seconds 
and counting. This is Gemini Launch Control.

This is Gemini Launch Control. T-16U minutes and counting. T-l6k. We've 
now completed our pressurization of the Gemini Launch Vehicle. All is looking 
well, and on our early checks since completing our pressurization a short while 
ago, show that we are getting good readings on the pressure in both stages. The 
backup pilots , Astronauts Jim Lovell and Buzz Aldrin, now have returned to the 
Gemini spacecraft. They spent some two hours and 1+5 minutes in it earlier and 
will go through some further checks pending the arrival of the prime pilots, 
Tom Stafford and Gene Cernan. 

All is going well in our countdown at the present time. We'll now switch 
you to the Mission Control Center in Houston. 

This is Gemini Control. The augmented docking adapter is now on its 28th 
revolution. It is over the north central portion of Africia. Earlier we reported 
that the network status was completely green, since that time a teletype trans- 
mitter at the Woomera, Australia station is apparently on the fritz, but the 
station can support, however. 

A short while ago, Mr. Allen Sandy Sanderson, of the Space Flight Meteorological 
Group, here in Mission Control briefed the Mission Director and the Flight Director 
on the global weather picture. At T-162 minutes and 32 seconds, this is Gemini

All still proceeding very well with the countdown at this time. 
At Launch Complex 19, they're in the mist of a guidance control 
test between the mark 3 Burroughs computer and the Gemini Launch 
Vehicle. It appears to be goin^; well at this time. Because of 
the problem we had on Wednesday that we scrub the launch that 
the ground support failure concerns with up-dating the spacecraft 
computer, we're going to make some extra checks and some extra 
data reports into the computer during todays countdown. The 
computer at the M'ssion Control Center in Houston will feed data 
up-date -to the Gemini spacecraft computer here at Launch Complex 
19? at the T-60 minute mark, T-30 minutes, T-15 minutes. We will 
feed the regular real-time up-date as we resume the count of 
T-3 minutes as reported yesterday the present plan is if we fail 
to get that up-date to the spacecraft T-3, we will still continue 
with the countdown and launch, using the latest data we ha e in 
the computer at that time. All is going well at T-152 minutes,

the erector down we will continue down with the count with some 
of the highlights being a report from the Flight Director at the 
T-kO minute mark on the Btatus of the ATDA which is coming around 
its 29 revolution. We will also test the propulsion system in 
the spacecraft at about the 20 minute mark. We're aiming toward 
an ignition of T-0 of the Gemini Launch Vehicle at 8:39 and 30 
seconds a.m. EST. Lift-off will come 3 seconds after ignition 
or 8:39, 33 EST. A built in hold to coincide our launch with 
the ATDA in orbit will be declared at the 3 minute mark in the 
count, duration of the hold, h minutes and 29 seconds. Now T-52 
minutes and U3 seconds in counting. This is Gemini Launch Control.

TAPE 23, PAGE 1 



This is Gemini Launch Control, T-UU minutes and counting. T-kk. 
Our countdown continues to proceed very well at this time. From 
their perch in the spacecraft at Launch Complex 19, Astronauts 
Tom Stafford and G ?ne Cernan took a moment to look out a short 
while ago. They commented on a cloud that was passing over the 
spacecraft and Gene Cernan said from his location he could look 
over the beach at Cape Kennedy. He noted that the sun was shining 
and it looked very beautiful over there on the beach. He also 
noticed a helicopter in the area, it was heading the general 
direction toward Launch Complex 19. As far as our computer 
situation is concerned today, we thought we'd mention a few facts 
about it at this time. In view of the problem that did cause the 
postponement of the launch on Wednesday, we will update the computer^ 
the spacecraft computer^ with the proper flight parameters in the 
following manner. We will feed the data directly from the computer 
at Houston. We've already done this once at the T-60 mark. 
There will be direct feeds from the Houston computer to the space- 
craft at T-30 and T-15 minutes in the count. After our hold at 
T-3 minutes when we resume the so called automatic update, will 
come from the GE Burroughs computer system here at the Cape and 
it will be fed through the ground support system, winding up 
with a signal being generated to the spacecraft. If .as on 
Wednesday, this signal is not received by the spacecraft computer, 
we will continue the countdown using the latest update data that 

the computer already has stored and launch with that update data. 

We are still preceeding very well with the countdown. We're a 
number a minutes ahead on certain events. It's very possible 
that the so called static test of the spacecraft propulsion system 
which is due at the 20 minute mark in the count may come earlier. 



\ 

GEMINI 9A (2) MISSION COMMENTARY, 6/3/66, 6:51 a.m. TAPE 23, PAGE 2 

As soon as the crew in the spacecraft and the crew in the blockhouse 
are ready, they will proceed with that test. We do not have a 
time on it now, but it may come earlier then the planned 20 Blinttte 
mark in the count. We will now switch to the Gemini Mission Control 
Center in Houston. 

This is Gemini Control in Houston. Our target vehicle at this 
time is on its 29 revolution. It is now roming up over the Carnarvon 
tracking station over Australia. Or at least within range? The 
target actually is still on a - off the west coast of Australia. 
Here in Mission Control our Flight Director has green and GO 
buttons from all his controllers. The countdown is proceeding 
and our Flight Director and our Flight Controllers are taking part 
in that countdown. Flight Director on duty with the White Team is 
Gene Kranz. Our Spacecraft Communicator this morning will be 
Astronaut's Neil Armstrong who is primary and Astronaut Dick 
Gordon assisting him. Mission Director, William Schneider of 
the Office of Manned Spaceflight in Washington is here and at 
his console as is our Flight Surgeon Dr. Owen Coons who will be on 
duty with the White Team this morning. In the viewing room early 
today were Dr. Robert Gilruth, Director of Manned Spacecraft Center 
and George Low our Deputy Director. This is Gemini Control in 
Houston, ho minutes, 37 seconds before liftoff. We are green and 

GO in Houston.

This is Gemini Launch Control. T-3*+ minutes and counting. 
T-3I+. All still going excellently on Launch Complex 19 and our 
Gemini 9 countdown. As the ATDA target continues to swing around 
on its 29th revolution. At this point in our countdown, we are 
going through a series of flight control checks with the Gemini 
Launch Vehicle and overall telemetry checks between the launch 
vehicle and the Air Force Eastern Test Range Tracking Elements. 
During this phase of the count also, the automatic sequencer, 
the so-called master operations control system, has come into 
effect in the Gemini countdown. This is the sequencer that 
controls and commands many of the actions that will occur over 
the final phases of the count. It will command some ten acti- 
vities and monitor some 25 of the functions until we get to 
the T-5 minute mark and then we have a completely automatic 
operation from T-5 down to ignition and liftoff. All systems 
and all checkouts still going very well at the Pad at the 
present time. At T-32 minutes and 5° seconds and counting, 
this is Gemini Launch Control.

still a little bit ahead on certain aspects of the countdown, however, this 
will have no effect on our launch time whatsoever. It remains at 8:39 and 
33 seconds A.M. EST. It has been reported a short while ago that we will be 
going on an azimuth of 87. k degrees. In the meantime, we have completed test- 
ing of the spacecraft propulsion system, these are the thrusters at the base 
of the adapter of the Gemini spacecraft. We have fired the thrusters in a 
series of tests and that has been very satisfactory. These are the 25-pound 
thrusters at the base of the adapter and the astronauts have fired the 
thrusters to check them out in the three modes of yaw — two modes of yaw 
and pitch. This is the propulsion system that will be used by the spacecraft 
in orbit. All is still going well. The thruster testy as reported, has been 
completed and now at T-23 minutes and counting. This is Gemini Launch Control.

GEMINI 9A MISSION COMMENTARY, 6/3/66, 7:21 am TAPE 26 PAGE 1 



This is Gemini Control T-lk minutes and counting. Here in 
Mission Control in Houston, we have had a final status check. 
Our Flight Controller, Gene Kranz, has received a green go from 
all his flight controllers. We also had a communications check 
with the worldwide tracking network and communications are loud 
and clear at all points. Our target vehicle is now in its 29th 
revolution over the Pacific Ocean, apogee l6l.9 nautical miles, 
perigee l6l.5 nautical miles. We launch this morning on an 
azimuth of 87. h degrees to the northeast. And during the lift- 
off, we will attempt to note for you the liftoff time the start 
of the spacecraft clock which is synchronized with our ground 
clocks. The start of the roll program which is supposed to 
start at 19 seconds, the start of the pitch program, cabin 
pressure will give you a 50 second mark at which time the space- 
craft and its launch vehicle will be moving 7^0 miles per hour 
or supersonic. We will note BECO, the booster engine cutoff 
point eight or 80 percent of the velocity needed for insertion 
at this time we are moving 18,000 feet per second. We will also 
note SECO, second stage engine cutoff and we will note whether 
we get a go for IVAR, which means that Tom Stafford will do the 
insertion velocity adjustment routine, firing his thrusters to 
correct any small inplane and velocity discrepancy the go for IVAR 
will be given by our Flight Dynamics Controller, Ed Pavelka. At 
this time we turn you back to the launch team at the Cape. 



GEMINI 9A MISSION COMMENTARY, 6/3/66, 7:21 am TAPE 26 PAGE 2 



This is Gemini Launch Control at T-12 minutes, 15 seconds and 
counting. All still going very well on the countdown at Launch 
Complex 19. During that status check on the spacecraft that was 
reported from Houston, the Command Pilot also checked in, Tom 
Stafford and reported that it looked very good. Here in the 
Control Center at the Cape now the backup pilots, Jim Lovell and 
Buzz Aldrin, along with Deke Slayton and Astronaut Pete Conrad 
are sitting near the old Cap Com position in the Mission Control 
Center, following the mission from here. At the launch pad, we 
are about to start one of the final key guidance checks between 
the Mod 3 Guidance System here at Cape Kennedy and the Gemini 
Launch Vehicle. We are getting reports that all is still going 
very well in the count at this time. T-ll minutes and 26 seconds

This is Gemini Launch Control. 1-h minutes and counting 
T-U. We will be going into a planned built-in hold in the 
three minute mark in the count- Duration of the hold about 
four and a half minutes, aiming toward an ignition of the 
Gemini Launch Vehicle at 8:39:30 EST We've gone through a 
whole series of status checks over the last several minutes. 
This included crewman one and crewman two in the spacecraft. 
Tom Stafford, when he reported in, used the term that his 
command pilot, Wally Schirra, used on the Gemini 6 Mission 
when it finally was launched. Stafford reported, "For the 
third time, Go," when he gave his status report. Gene Cernan 
reported a little after that as he thanked the crew for their 
efforts and suggested that they all take a vacation, but then 
pointed out that they shouldn't start until about two seconds 
after ignition which, of course, would be just prior to lift- 
off of the Gemini vehicle. Now coming up on the hold. T-3 
minutes and holding. T-3 minutes and holding. The hold is 
expected to last for about four and a half minutes. We'll 
be resuming the countdown at 36 minutes and 30 seconds after

This is Gemini Launch Control. We're still at T-3 minutes and 
holding. Our checkouts during the hold period at the present 
time, all going well. We'll be picking up the count in about 
two minutes from this time, aiming towards a liftoff of 36 minutes 
and correction 39 minutes and 33 seconds after the hour. Once we 
do pick up the countdown one of the first activities once again 
will be the so called computer update. This is a feed from the 
GE Burroughs Guidance System to some ground systems here at the 
Cape and finally by radio frequency signal to the spacecraft 
itself. If this does not occur, if the information is either re- 
jected or if the signal does not get to the computer as occurred 
on Wednesday, we still will continue our countdown and go with 
the update parameters that were loaded aboard from Houston at 
the T-15 Mark in the countdown. All systems still going well at 
this time. During the final phases of the count, we're all on 
an automatic sequence at this time. The supervisor of range opera- 
tion will give a clear to launch at about 2 minutes and 30 seconds. 
The power transfer will go on internal power to vehicle at one 
minute and 30 seconds and counting. The engines will be gimbaled 
both two - ah thrust chambers on the first stage of the Gemini will 
be gimbaled at one minute 20 seconds. The astronauts will be 
alerted of this because they will be able to feel this motion, in 
the Gemini spacecraft. The prevalves in the second stage that 

permits the oxidizing fuel to operate in the second stage will be 
opened at the 35 second mark. We'll get ignition at the zero mark 
in the countdown with a liftoff about three seconds thereafter. 
We'll be picking up the count shortly, still T-3 minutes and holding 
at this time. About five or six seconds from now we will resume

This is Gemini Control, w? are 2o minutes and 25 seconds into our 
mission. At this time, the spacecraft and its target are passing over 
the tracking range of our Kano, Nigeria tracking station. The space- 
craft is in an orbit of 86 nautical miles by ikh nautical miles. This 
is additional information on the orbit that was picked up at the Bermuda 
tracking site, from the Bermuda tracking data and this will be farther 
refined as we get the Canary Island data reduced. I would like now to 
take you back to the final moments of the countdown when we reported 
a switchover on our guidance here at Mission Control. What actually 
happened during the final minutes of the countdown, there was an attempt 
to put an update into the launch vehicle at T-3 3 this update did not go' 
into the launch vehicle program, therefore, the switchover flashed here 
however, it had been decided if we did not get that countdown — or that 
update in, we would go with the update that we put in at T-15 and so we 
did launch and everything was normal since we launched on the time that 
was programmed -- 8:39:33 and we launched on t he second. So, the T-15 
data was perfectly good. This is Gemini Control, 27 minutes and 56 seconds

This is Gemini Control, we are 1 hour and 55 minutes and 20 seconds 

into our mission. The spacecraft and the target vehicle are now 

moving towards the coast of Africa. The west coast of Africa and 

within range of our Kano Tracking Station. We have some word 

from our Flight Surgeon, Dr. Owen Coons. He said the biomedical 

data on the crew is very good. We have some additional information 

on the next event which will occur. The corrective combination 

maneuver which will occur at a ground elapse time of 1 hour, 55 

minutes and 17 seconds. This burn will be with the aft thrusters. 

Tom Stafford burning the aft thrusters to increase this velocity 

by lU.6 feet per second. Fourteen point six feet per second. The 

burn time will be 19 seconds, he will yaw 67 degrees left and 

pitch up kO degrees. This burn will be followed with a second 

burn designated the NSR burn or coelliptical burn, designed to 

make the spacecraft orbit coelliptical. This will take place at 

a ground elapse time of 2 hours, 2k minutes and 51 seconds. Again 

the aft thrusters will be used. The burning will be at a rate 

of 5*+ feet per second and the burn time will be 1 minute and 

11 seconds. The yaw will be three degrees left and pitch hi 

degrees down. The corrective combination maneuver is designed 

to correct small discrepancies in the phasing, height and out-of- 

plane position of the spacecraft. The coelliptical burn of course 

is to make the orbit coelliptic. We have additional information, 

aboard the spacecraft, the jack outlet or plug similar to a plug 

that would be found in the ordinary home, this plug on the left 

side or at Cernan's seat is presently inoperative. Stafford plans

HOU Understand. 
TAN Tananarive has LOS . 

This is Gemini Control at two hours 28 minutes and 30 seconds 
into the mission and we have just played back the voice tape 
between the Mission Control remote voice through Tananarive and 
the spacecraft. At this time the spacecraft and the target are 
passing over the tracking range of the Carnarvon, Australian station 
and we understand they have reported from Carnarvon that Tom Stafford 
has completed his co-elliptic burn. We will have the new orbit 
values as soon as they are plotted. Meantime at this time we will 
play back the voice communications between Carnarvon and the space- 
craft .

HAW Roger , go ahead . 

S/c Roger. We noticed this after the NSR burn that 



every time we go ftm rendezvous back to catchup 
the comp light would come on without starting and 
the IVI's would display. Could show we're getting 
some signal in that would start the computation 
cycle. Okay, went to rendezvous and after the 
total data points when we got the first solution 
displayed, the start comp light came on and it 
cranked up the solution, what it would be for this 
range. And we were not given a second data point. 
We went to catch up mode and had the same values 
at catch up that we had in rendezvous and that's 
when the light was on which shows we're holding in 
the register. It appears that after every eight 
data points all we're getting is that solution and 
nothing more. Our Delta Delta R shows we're about 
two and a half miles high for fifteen which is 12.5.

pardon, correction here, I mean Bermuda and Antigua. The spacecraft is now 
approximately 25 to 30 miles trailing the target and you heard Tom Stafford 
that he thought he saw a real faint light in the direction of the target, 
that it was too early to tell. This could be the acquisition light of the 
target vehicle and if so, the target would have the shroud separated. 
However, it is too early to tell whether that light he did see was the 
acquisition light or beacon, on the target. This is Gemini Control. We

and to determine the rates on the ATDA. And also, to determine whether they 
can dock should the shroud be removed. This Is Gemini Control, four hours 
and 20 minutes into the mission. We are standing by for our Hawaii pass.

This is Gemini Control in Houston at four hours and 26 minutes into 
the flight. We have established contact with Gemini 9 over the Hawaiian 
tracking station. Tom Stafford reports we have a weard looking machine, 
the clam shells are on — the shroud clam: shellc are on but they are open 
wide and evidentally the bolts are blown and we will pick up now that voice 
communication between Hawaii and Gemini 9. 



S/C Hello Houston, Gemini 9- 

HAW Gemini 9, Hawaii. 

S/C Hawaii, we've got a wieafil looking machine here. 

HAW What does it look like? 

S/c Okay, both the clam shells of the nose cone are 



still on but they are open wide. The front re- 
lease has let go and the back explosive bolts 
attached to the ATDA have both fired. It 
appears that one of the bolts of the band has 
fired. The ones that do fit together is the 
quick disconnector, a small electrical connector 
that fires the bolts on the band. 
HAW Roger, understand. 

S/C The jaws are like an alligator jaw thats open 

at about 25 to 30 degrees and both the piston 
springs looks like are fully extended. 

HAW Roger. 

S/C Also the back parts of the nose cone have separated 

from the/ V/ ATDA. It looks like its just held on 
by some inconceivable force. But everything looks 
good . 

HAW Roger, we understand.

Rog. It"s got smudge marks on it. We're now about 
thfe^ feet from it and the electrical connectors 
that should disconnect did not disconnect on either 
one of them. 

They did not disconnect? Is that right? 
The band that's holding the whole mess together • — 
Stand by one till I give youthe distance on this 
other one — I'm trying to find the cable disconnect. 
I can't see the disconnect; of course it would be 
blocked. Okay the other one is.... the spring' ic gone 
from the back of the other aft one and no part is 
still there. Its separated - the' back is completely 
separated three to four inches and I'll give you 
another good check. The only thing that is holding 
the whole mess on there is the bands. Rapid firing 
would fire those disconnects on one. 
Roger understand. 

We've got about three minutes here until our LOS. 
We'd like to go through one rigidized and unrigidized 
sequence and then you watch it if ' you'd get into the 
station where you could watch it from. 
Standby one. I don't want to be to close to it 
we're fixing to cut loose. 

Roger, understand. 

Okay, now on the other side, both explosive bolts on 
the band have fired. The band is held intact by all 
four of those electrical pryos that fire the bolts.

S/C Disconnect did not disconnect thats the only thing 

thats holding the whole mass intact. 
HAW Roger. 

S/C Don't want a rigidize yet can we hack it over the 

states? 

HAW Roger, I wis just going to suggest it. I'm getting 

to close to LOS.

we're going to continue working on their description 
and we'll cycle the adapter and we'll pick them up 
over the states here. 

HAW Okay, very good. 

HAW Gemini 9> Hawaii. ' 

S/C Go ahead Hawaii. 

HAW Houston wants to wait and take a look at it and 

try cycling your adapter over the states. 

S/C We'll get back in a set position and again pass on 

to them all four explosive bolts have fired. It is 
basically free of the docker and are resting on it. 
We can see its activator and those four little pyro 
wires which is definitely holding the whole thing. 

HAW Okay we're having LOS. 

S/C The springs have .just about distributed full force. 

HAW We've aad LOP Flight. 

That was voice ommunication between the Hawaiian tracking station 

and Gemini 9 and you heard Tom Stafford five a very vivid description 

of the status of the shroud that is still hanging to our target 

vehicle. Our next communication of course will come when we get 

over the state side pass, in a f ev, minutes and we will attempt to 

bring further information at that time. Hopefully, a plan whereby 

we can release the shroud. This is Gemini Control at k hours, 'ih minutes

CAP COM You see anything about those? 

S/C The (garbled) is too much, Neil, I can't see it. 

CAP COM Roger, I understand. 

S/C The clamp shells at the back are between fou 1 " 

and five inches apart. Coils springs, one of the 
is beginning to part, the other is still attached. 
The basic nose cone has detached around the ATDA 
ring and the only thing holding it together are 
those yellow wires that go... went to the initiation 
of the explosive bolts of the straps. 

CAP COM I understand. Can you... you cannot tell whether 

the disconnects have pulled, is that correct? 
Wire bundle disconnects? 

S/C That's affirmative. What's holding it together 

are the four small plugs that should have put 
disconnects either on the pyros or the straps. 
The whole thing is just loosely hanging on there, 
we're standing by for an unrigidized sequencing, 
if we would get it right now it would be great. 

CAP COM Roger, we'll have to wait until we get over Texas. 

S/C Okay. 

CAP COM Wait a minute, it will be about six minutes from 

now when we are over, when we get in Canaveral, 

uh, acquisition.

Sep when you are ready to copy. 

S/C Roger for radio Sep. You want us to stand, by 

here and talk this thing over for a minute and see 
if we can't possibly. . .1 'd like to look at the idea 
of possibly extending the docking bar and going up to 
touching it, the whole thing may fall apart. 

CAP COM Ok, we've got about 23 minutes left. The radio 

Sep, I'd like to give you that first. 

S/C Ok. Go ahead, Neil.

seconds. Pitch is 90 down, address 250, address 
26 90200. 27 zip, forward thrusters up maneuver.

CAP COM Roger. 25 is all zip's, 26 90200, and 27 zips' s, 

that Delta V is 20 feet per second.

CAP COM Roger. It sounds to us like perhaps the cables 

haven't pulled the disconnects to the wire bundles 
in which case we would definitely have to wait until., 
with the contingency plan B there, wait until later 
to look at that. We will go ahead and exercise that

much time to do what you like. 

S/C OX Neil, from here it looks like its very possible 

that the wire bundles, that these wire bundles could 

sure 

have separated. It's/hard to see, but again, is 
everybody squared away on what is holding the thing 
together? 

CAP COM Well, I think everybody down here is pretty well 

convinced by your description of the situation. 

S/C Yeah, ok. 1 can't realjr tell what.... we have two 

big umbilicles that goes to the ATDA, I can't tell 
whether those are still attached or not but it is 
the four little wires that go to each of the explosive 
bolts on the straps that's supposed to have a 
disconnect on it and those are all intact and all 
four eKplosive bolts were fired. So it's just the 
four disconnect umbilicals on the strap that have 
not pulled. All four of them are still intact and 
all four should have pulled.

S/C We did send an L-band command and the acq lights 

are off.

of your start comp light when you are in catch up 
now? 

S/C Start comp light is working fine, everything appears 

to be normal. It was just a little anxious to 
rendezvous I guess. After we once accepted its 
solution, things went real well. 

CAP COM Ok. 

S/C We still have about 57$ fuel.

in position for platform align as soon as this 

is over? 

S/C Oh, not too long. 

CAP COM Ok, we're going to be running out of alignment 

time here. Your pitch will probably be in in 
about five minutes or so so we'll have probably 
a little shorter alignment time, but it'll be

in approximately two and one half miles above the target and they will 
reach a maximum separation from the target of approximately 11 miles. 
They will be behind the target approximately 11 miles and will come up 
again and rerendezvous with the target. During this - after the burn is 
completed, there will be necessary, a slight mid-course correction, which 
will be figured out by the crew aboard Gemini 9- This is Gemini Control

target, on its 3*+th revolution. Both vehicles are passing over 
the northern part of South America at this time. We have a 
report that the pressure and temperature readings obtained from 
the AMU, astronaut maneuvering unit, during the boost phase and 
while it is in orbit indicate that conditions of the hydrogen 
nroxide duel very closely approximate those that pertained on 
the pad prior to launch. CUrrent readings are pressure 90 pounds 
psi at temperature 77 degrees. Captain John Donohue, Air Force

This is Gemini Control at five hours and three minutes into 
our mission. The spacecraft Gemini 9 and out target vehicle are 
passing over the Rose Knot tracking ship. Within range of that 
tracking ship Stafford reported he has fuel remaining of 50% and 
he has completed his equi-period re-rendezvous burn which will 
place him two and one half miles above the target and the maximum 
separation between the two vehicles will be 11 miles, the space- 
craft being behind. During the contact we had, the visual contact, 
between Gemini 9 and the target the ring A fuel system aboard the 
target, the thruster system, was not activated and, therefore, ring A 
is still available should we arrive at a solution for this shroud 
which is still hanging on to the target vehicle. While this equi- 
period re-rendezvous is being made or, as it is being made, the 
flight controllers here will be evaluating the shroud situation and 
we hope to come up with some answers. This is Gemini Control, five

The range should be in the order of 11 nautical miles, which is the maximum 
separation range during this maneuver. This is Gemini Control at six hours 
and one minute into the flight.

This is Gemini Control at six hours and ten minutes into our mission. 
Gemini 9 and the target vehicle are now passing over the Pacific. They have 
just passed beyond range of the Hawaiian Tracking Station. Our crew is still 
performing the equal period re-rendezvous maneuver. Hawaii reported all 
systems look good from the ground aboard the Gemini 9- At this time Gemini 
9 is below the target and at a range of approximately eight nautical miles. 
Tom Stafford should begin his terminal phase initiation in about ten minutes. 
At this time we will play back the voice tape taken between Hawaii and the 
Gemini 9 crew. 



s/c Hello Hawaii, Gemini 9. 

HAW Gemini 9, Hawaii. 

S/C We're still aligning our platform. We are stand- 

ing by to roll inverted in approximately 15 minutes. 
HAW Roger, we Ml be getting a tape dump on this pass. 

S/C Say again. 

HAW We'll be getting a tape dump on this pass. 

S/C Rog. What about the ATDA? 

HAW We haven't got any more words on it. 

S/C Okay. I still suggest that we try to give it 

a one sided bumper with our docking barge to 

see if we can't break it loose. 
HAW We heard that. 

HOU Houston has your input. 

HAW Okay, 

We have solid TM on both burns and all systems 

look good and we're copying the tape dumps.

HOU FLIGHT Okay. 

HAW We got a good tape dump. 

HOU FLIGHT Roger, Hawaii. 

HAW Gemini 9, Hawaii. We have 30 seconds to LOS. 

Hawaii has LOS on both vehicles. 
That was tape voice communications between Hawaii and Gemini 9 flight 
crew. The spacecraft is now coming toward the states. And we expect our 
state side pass shortly. We expect to establish communicatins shortly. At 
this time the spacecraft is below target vehicle and should be within a 
range of approximately six miles. We will stand by now to bring you the 
voice communication from the state side pass.

This is Gemini Control, we are six hours and 22 minutes into the mission. 
Our Gemini 9 crew has passed out of the range of our state side tracking 
stations. The flight crew is still in the re-rendeevous — the equal period 
re-rendezvous — and they should be very close to the target vehicle at this 
time so close that we cannot estimate their distance on our little chart that 
we have to work with. The spacecraft was coming up from below and within a 
very few minutes, Command Pilot Tom Stafford will start his terminal phase 
final approach. This is Gemini Control at six hours and 22 minutes into the

This is Gemini Control at six hours, kO minutes into the 
flight. Gemini 9 has concluded its equi-period rendezvous and 
is now station keeping- They have just performed a fuel cell 
purge. Command Pilot Tom Stafford reports he completed this 
rendezvous with k2% of his fuel remaining which is within the 
limits. At seven hours, lU minutes, 58 seconds elapsed time, 
the crew will do its separation maneuver for the third rendez- 
vous. This will be a six second burn or a Delta V of 3-7 feet 
per second. A retrograde maneuver which will put the spacecraft 
below the target vehicle, therefore, in a faster orbit, and 
through the night cycle it will get ahead of the target vehicle. 
We have now a tape of the pass over the Range Knot - the Rose

Gemini 9 is over the Indian Ocean out of range of any tracking 
station. We are about U minutes away from the terminal maneuver, - 
from the separation maneuver at the present time. The communications 
with the Coastal Sentry Quebec are rather poor right now but 
we hope they are in better shape when we do have acquisition of 
the spacecraft at that time, and are able to get a rundown on this

This is Gemini Control at eight hours into the mission. The Gemini 9 
spacecraft is approaching the West Coast of South America. The crew is 
eating their evening meal right now. Voice communications between the 
control center and the Coastal Sentry Quebec were very bad during the 
pass over that station, we were forced to go to teletype. We did ascertain 
that Tom Stafford is completely satisfied with his separation burn. He 
has tracked the ATDA On radar and is satisfied with the separation. He 
reported h0% OAMS fuel remaining. The Gemini 9's orbit is now 160 by 
158 nautical miles, the Augmented Target Docking Adapter is in an orbit 
l6l by 159 nautical miles. During the night Gemini 9 will gradually 
pull away from the ATDA and will -- by the time the crew awakens will be 
approximately 60 miles ahead of it. We will update the crew at that time 
on the further maneuvers to be done for this rendezvous from above — where 
the spacecraft will approach the target vehicle from above. We did have 
good communications over the Hawaii tracking station and we'll play that 
tape for you now.

This is Gemini Control at 8 hours, 10 minutes into the flight and 
Gemini 9 has just been acquired by the Rose Knot Victor tracking ship 
off the coast of South America. Gemini 9 just began its sixth revolution 
a short time ago and we'll tune in now and see if we can hear some of 
the conversation from the Rose Knot to the spacecraft. 



S/C (Garbled) 
RKV Say again. 

S/C It doesn't make any difference, we can rendezvous 

in about any type of situation you give us. 

RKV Ok, they would kind of like to try this type of 

approach, daylight from above. 

S/C (Garbled) 

RKV Ok, Gemini 9. We would also like to get confirmation 

that you have the C-bands in the command position. 

S/e adapter continuous reentry to command, we'll 

go adapter to command. 

RKV Roger 

S/C RKV this is Gemini 9. Our fuel budget looks pretty 

good. 

RKV Say again. 

S/C Roger. Looks like we have enough fuel to hack it. 

RKV Roger , very good . 

RKV Cape Flight we are showing on the current , main 

bus current which shows that the ATDA lights are 
still on. 

HOU FLT RKV Flight. We are going to leave the running lights 

on. We want to be sure the acq lights are off, 
the acquisition lights. 



GEMINI 9A. (2) MISSION COMMENTARY, 6/3/66, 3:50 p.m. Tape 6k, Page 2 



RKV Ok, fine, we'll go with it. 

HOU FLT Do you concur that it looks like they are off. 

RKV No, we are not sure, we think one set of the 

lights are on, but... 
HOU FLT That will be the running lights. 

RKV Ok, we are not positive of the other, that's for 

sure . 

HOU FLT Ok. 

RKV Ok, Gemini 9, we just put a TX into the spacecraft 

to turn TM off for us after LOS. 
S/C Roger, we saw the light. 

RKV Roger. 

HOU FLT RKV, did you command his C-band on? 

RKV That's affirm. Oh, which C-band did you want on? 

HOU FLT That's on Gemini. Oh ignore that. We're going to 

turn it on next rev, disregard this one. 

RKV Ok, he's got both C-bands in command position and 

with the TX in there its gonna shut both the space- 
craft C-bands off. 

HOU FLT Roger, that's complete configuration I gave you. 

RKV Very good, and we have turned the C-band number one 

on the ATDA. 
HOU FLT Roger. 

HOU FLT RKV Flight. We would like a Gemini main. 

RKV Roger, do you want it at LOS or now. 

HOU FLT Why don't you give us one now and at LOS?

S/C Roger. 

RKV Ok, flight, I'm not sure he had his TM switch in 

the right conf iguration. We sent a TX but we did 
not get a cutoff at TX time. 

HOU FLT Roger. 

RKV It might be ok to have the next site check with him 

on the switch position. 
HOU FLT Roger, we'll have him check to see if he's got the

HOU Roger Tom. I have some questions from the Cape 

concerning the shruud. 

S/C Go ahead. I guess we're the experts. 

HOU Yes, I'm sure you are. 

I understand the shroud gap at the base of its about 
three or four inches, is that correct? 

S/C That is affirmative. Its about three or four inches 

wide down at the (garbled) of the explosive bolts 
at the base of the shroud where it touches (garbled) 
in between. Cm coil spring was attached, still 
in between both of them. The other spring wasn't, 
(garbled) 

HOU Roger, understand. C in you estimate the gap between 

the shroud at the strap and also at the apex. 
Over . 

S/C And then there was these small wires hooked to a 

connector that pulls the bolts. 
HOU Nine, Houston. 

Gemini 9 Houston. 
S/C Stroked to the maximum, when the signal was sent to 

unrigidiz control unit B in vacuum four wac real 

loose there. I'd say about IS to 20 degrees. 
HOU Roger Tom. Let me ask you some questions about it. 

Can you estimate the distance between the shroud 

at the strap and also at the apex? Over. 
S/C Say again. 



GEMINI -)k (2) MISSION COMMENTARY, 6/3/06, k:20 p.m. 



TAPE PAGE 3 



HOU Distance between the ;;hroud halves at the strap 

and at the apex. 

S/C Roger. It's kind of hard to tell but it stretches 

it out about six inches. 
HOU Okay. What about the apex of it? 

S/C At the top of it 

HOU Yes Tom 

S/C Its a good two and a half feet, maybe three feet. 

HOU Okay does the strap appear to be tight or does 

it appear to be loose? 
S/C Let's take the shroud. Its extended out/£ne length 

of those two p/ro connectors on each bolt. It opened 
the back in about four inches and opens up like 

a couple of jaws and you have the total configuration. 

The wedge angle between the two halves is a good 

20 degrees, maybe in excess to that. 
HOU Okay. Can you tell the lengths of the spring cartridges? 

Can you see those well enough to tell me if they 

look like their fully extended? 
S/C The spring cartridges look like they have just about 

reached their fuLl stroke from the ones that we saw 

at the Cape the other day. 
HOU Okay, understand. Does it look like you can get to 

the lanyard on the pyro wires just inside the shroud? 

Over. 

S/C Theres still connectors there that - from all that I 

can see the pressure was up before the lanyards were 
ever installed. 



GEMINI 9A (P.) MISSION COMMENTARY, 6/3/66, k:20 p.m. 



TAPE 65, PAGE h ' 



HOU Okay, you think the lanyards are not even there? 

S/C I looked as we flew in within a couple of feet 

or about as close as I could get the with the 
rear (garbled) snips, save (garbled) which was 
about two feet. I could plainly see the insulation 
on the wiring, it was frayed. You could see the 
connectors where they hooked into the bolts and the 
way it was (garbled). But I couldn't actually see 
the lanyards on it. 

HOU Okay. I understand. If that thing is opened far 

enough do you think that you could get in to pull 
the lanyards on the QD on the umbilical? Over. 

S/C Svy again. 

HOU Do you think you could pull the lanyard on the 

quick disconnect inside the shroud? 

S/C Let me have Gene talk to you on that. 

HOU Understand and one last question on the shroud. Has 

it moved in relationship to the TDA? Has it shifted 
fore and aft or has it rotated any? Over . 

S/C It pitched up and down. In other words when the 

unrigidized and rigidized (garbled) it opened and 
closed. The data opened and closed a little bit 
and then rotated. The total X axis cf the shroud 
pitched up and down a little bit, about 15 degrees. 
The .jaws opened a little bit. 

HOU Understand. Did you say it did rotate also? 

S/c No not much rotation is visual, mostly just the total 

shroud mass pitched up and down about 15 degrees. 



GEMINI 9A (2) MISSION COMMENTARY, 6/3/66, k:20 p.m. 



TAPE 65, PAGE 5 



HOU Okay, I understand. I think we've talked about 

that shroud long enough. You can ignore this 
locking on the target again at CSQ. Don't 
bother doing that. We're satisfied with the 
separation ourselves. The S-12 experimenter 
wants you to listen for the door opening when 
you activate that before the sleep period. Over. 

S/C Say again. 

HOU When you activate S-12 the experimenter would 

like to have you listen and see if you can hear 

the door opening. 
S/C Roger, will do that. 

Understand. What is the latest plans for EVA in 

the morning? Are they going to do it with the 

ATDA or without it? 
HOU Tom, we're going to do it with the ATDA. And, 

we'll do it - we'll do the EVA prep right after 

re -rendezvous . Over. 
S/C Roger. 

HOU If we do that re-rendezvous in daylight which we 

would like to do down here , we ' re going to cut a 
little bit into your EVA prep but it still should 
give you about three hours and 1+5 minutes. Over. 

S/C Okay. We'll probably need every bit of it. 

HOU V/ell don't rush it. We think we can give you plenty 

of time to do that. But, it will be after the 
re-rendezvous . 



GEMINI 9A (2) MISSION COMMENTARY, 6/3/66, h:20 p.m. TAPE 65, PAGE 6 

S/C How does the fuel budget down there? It looks 

like we have plenty for using a delta H at seven 
miles . 

HOU Yes, we think your in good shape. 

S/C Yes I think we're in real good shape on the fuel. 

Okay, we're still keeping both cooling pumps on. 

A pump and both suit fans on. We're still a little 

warm in here . 

HOU Oriay, you might as well leave them on until you cool 

down and we'll talk to you about the temperature 
again over CSQ,. 

S/C Okay, we'll find It. 

HOU Nine Houston, Tom have you had a chance to look at 

that auxiliary receptacle yet? 
S/C No, we're still busy trying to get some food and 

get squared away. We'll do this in the next hour 

or so, 

HOU Okay. If you can't get that left one fixed,, we've 

got a plan down here that you could use the right 
one but we'll hold up and wait and see what you say 
about it . 

S/C OK. 

HOU Nine Houston. We have 15 seconds to Tananarive LOS

separation maneuver was a good one. The range is now about 20 miles between 
the vehicles, with Gemini 9 .ahead and below of the target vehicle. This 
sleep periods ends at 17 hours elapsed time since liftoff. That will be

take place one hour slater, 18 hours elapsed time. At that time the Gemini 9 
range from the target vehicle will be about 80 miles. This maneuver will 
place the Gemini apogee seven miles above the target, then the crew wil.1 
perform a co-elleptic maneuver to make the Delta H or the difference in

to control exposure of special prepared plates and also to determine the effects 
of space environment on biological specimens. After the crew wakes up they will 
close this door over the experiment package by electric motor which drives the 
cover and the experiment will later be brought in the cabin at the end of the 
extravehicular activities and stored for study by the experimenter after recovery 
of the spacecraft. One purpose of running the experiment during the sleep period, 
is that the spacecraft is in a drifting flight and no thrusters are being fired 
and therefore the experiment plates would not be contaminated. 

At lh hours and 12 minutes and ^5 seconds after lift-off, this is Gemini 
Control.

Green team of Flight Controllers is taking over here in Mission Control, 
from the Black team. Gemini 9 is now in its 10th revolution, the target 
is in its 39th revolution. The tracking ship Coastal Sentry should acquire 
the spacecraft in about 7 minutes. During the pass over the tracking 
ship Rose Knot, during the last revolution, Spacecraft Connnuicator , C&jf*h 
KundM, confirmed that both vehicles were go as it went over the hill. The 
Flight Director released the RKV for the night, since no more of the space-

This 1 k Gemini Control, lB hours 10 minutes and 30 seconds after lift-off. 
Gemini 9, presently, is in the 12th revolution over Arabia, during the 
p reseni pass over the Eastern Test Range the Spacecraft Coramuicator Neil 
Armstrong here in Mission Control, gave Gemini 9 a call. The crew was 
awake at that time, in fact they had already started powering up the 
spacecraft and they further confirm that the door to the micrometerorite 
collection experiment outside the spacecraft on the adapter section have 
been closed at that time. Armstrong passed up to the crew several maneuver 
up-dates, and gave them a go to begin a fuel cell purge. Shortly thereaftee 
the spacecraft passed over the Canary Island tracking station, at which, 
time the plan landing area up-dates for several revolutions in the future, 
were passed up to the crew. We have a tape of the combined passes over the 
Antifn:'i station, Canary Islands, and a brief exchange of comment between 
Neil Armstrong and the crew over the Kano, Nigeria, voice remoting station.

Gemini 9 presently is over the South Central Pacific and has just passed the 
Carnarvon, Australia, tracking station. Command Pilot Stafford reported that 
on the phase adjust maneuver there were no residuals. They were all zeros on 
the TVI which means that the burn was done properly, and there were no errors 
that crept in. The spacecraft communicator at Carnarvon advised the crew that 
there were some flight plan updates coming up. For instance, over Antigua, 
they would get a go-no go for landing area 31-1 j and that over Canary, the. 
crew is scheduled to make a status report. We have a tape of this brief pass

and they should be beginning the preparation for extravehicular activity and

group here in Mission Control said that weather conditions remain satisfactory 
in the areas of prime concern for continutation of the flight of Gemini 9 
during the next two days and probably through the remainder of the mission. 
The mid -Pacific landing zone centered about 300 miles north east of 
Honolulu, has partly cloudy skys, winds out of the southeast as you were south

of trouble spotting the target vehicle against a sun-lit ocean. • We expect 
a rather extensive briefing on our EVA plans as the spacecraft moves across

This is Gemini Control Houston. We were in contact with the spacecraft 
a few minutes over, a few minutes ago over Canton Island and the status 
of the pilots was asked by Neil Armstrong. Tom Stafford gave us a summary 
that went something like this "we* re pretty well bushed" and he also raised 
for the first time some question in his own mind, having talked it over 
he said with Gene Cernan, he questioned whether, and when EVA should be 
done. It is his suggestion that perhaps the EVA event should wait till 
tomorrow morning, he realizes the alternatives are that where some experiments 
could be done, and he qualified it by saying we have a specific plan for the 
ATDA, suggesting the release of the shroud, and suggesting go ahead with 
some docking practice. He questioned the need for EVA, as presently planned 
for 25 hours and 10 minutes. There has been considerable work done during 
the night on a plan for EVA which will discussed at length over the states 
in some 10 to 12 minutes from now. Meanwhile the Surgeon reports that the 
crew got approximately 8 hours sleep last night, it was described as 
dozing sleep, not at all solid. They both sound a little tired this morning. 
They have been working hard to carry out this rendezvous from above. The crew 
has also had total of 110 ounces of water we can't break that down per man

Within the last few minutes in conversation with the crew the decision has

I say a&ain, a decision has been reached to postpone the EVA activity. 
The crew reaction of this was a statement from Tom Stafford — "We agree : 
very heartily with that recommendation." Additional work is a foot how- 
ever, in an attempt to shake loose the shroud still enclosing the target 

docking adapter ring. And this activity will go on during this pass. " 
presently 

The spacecraft/just crossing the east coast of Mexico in the Gulf. 
The crew is standing by in order to get photographs of this operation. 
The plan is this — we will activate- Ring A of the ATDA, that is the re- 
action control system ring, which still has a full 35 pounds of fuel avail- 
able in it, we will cycle the rigidieing-non-rigidizing sequence, that is 
move the docking adapter oone in and out and at the same time, we will 
pitch up and down the ATDA itself, in an attempt obviously to shake the 
clam shells loose, they are still being held together by at least two 
wire bundles, perhaps two more inside. But we know there^are two connecting 
externally. As near as can be observed, those are the only two bundles 
connecting. The bolts — stainless st<eel belly band — about the outside 
of the adapter clam shells have been blown and are free. The status of 
the ATDA in addition to Ring A, and its fuel, which I have given you, the 
squib batteries which activate the pyro circuits, an independent battery 
system from the main system — the squib battery still contains three amps 
or 20$, of the power. The main battery system still has 621 amps, this is 
approximately 60$ of the power remaining since take off. Commands are 



GEMINI 9A (2) MISSION COMMENTARY, 6/h/66, 6:06 a.m. Tape 91, Page 2 

going up to the ATDA at this time. The command to the — the primary execute 
command to the ATDA has been sent, and a signal verifying receipt has been 
received. The Ring A squib buss has been on. We don't have an exact posi- 
tion on where Gemini 9 is, we would estimate it is 100 to 150 feet from 
the ATDA. Additional commands going up to the Agena. Stafford has come 
in several times to report that the same rates that he has observed still 
obtained with the ATDA. But this is understandable, because I don't think 
the pitching motion has been introduced as yet. Now the RCS Ring A has 
been activated and Stafford confirms visually that this stopped the 
rates abruptly. The slight roll rate which the ATDA had been maintain- 
ing. He says the rates have been pretty well damped. Stafford says the 
ATDA is rolling to the left about two degrees per second. The expecta- 
tion is this series of maneuvers, which will continue out to into the middle 
of the Atlantic Ocean, may very well deplete the fuel supply in Ring A, 
but the feeling is, that it will be well worth the effort. We are now 
preparing to send the rigidized-unrigidized command. A rigidized command 

has been sent and a message of acceptance has been received. And Tom 

thruster 

says, they ' re 1 really tossing the/fuel out now, while this rigidizing- 
unrigidizing sequence goes on. The thruster fuel of course, coming from 
the target vehicle. All the while, Stafford and Cernan are taking pictures 
of this activity. It should be a remarkable photographic record. We're 
going to the unrigidized sequence. Tom Stafford reports he's already 
expended one can of film. He wants to reload. We have unrigidized the 
cone, the signal has gone up -- an acceptance signal has come tack. 

The Flight Director has ordered that we return the ATDA to a low rate 
load. Tom Stafford has remarked several times of the unusual thruster 
activity he's observing. Stafford estimates his present pnboard propellant 



GEMINI 9k (2) MISSION COMMENTARY, 6/h/66, 6:06 a.m. Tape 91, Page 3 

quantity reading is 12 to 13$. He says the target vehicle thrusters are 
still firing very rapidly and he has asked the flight directornand should 
he maintain a station keeping position kith the target vehicle for another 
rev that decision has been postponed for about 10 minutes, until we are 
within the Canary area of acquisition. We have lost telemetry contact 
with the target vehicle right now which is out some 500-800 miles east 
of Bermuda. She preliminary indication is that this series of maneuvers 
introduced across the states apparently was without effect. We've heard 
nothing from the crew. Our TM shows also that we did not have much suc- 
cess. The clam shells apparently are still around the docking cone. 
To recap this rather extraordinary active pass — a decision was reached 
and passed to the crew at the beginning of the pass that any EVA considera- 
tions on the EVA which had been scheduled for about 25 hours and 10 
minutes into the flight would be postponed until at least tomorrow 
mDDiijLng. The one possible fact that could have changed that decision would 
have been the success of jettisoning these panels, shaking them loose 
somehow. And, in an attempt to to that a series of bucking pitching up and 
dawn motions were introduced into the ATDA by going to Ring A and at the 
same time, several rigidizing and unrigidizing command svwece sent to the 
docking cone, Apparently, without success. We are now prepared to play 
the tape as we moved access the states, the communicator from the space- 
craft is Tom Stafford. You will also hear some discussion from our Agena 
console operator and I believe Gene Kranz the flight director, also gets 
on the loop from time to time. Here's that tape.

Were you able to find out Neil whether theres 
anything we could do EVA to the ATDA that might 
afford us a docking? 

We've looked into it rather extensively and we had 
some possible actions. However, we did not have a 
very high confidence level in those actions. 
Now, Tom and I discussed this whole thing and I 
guess the real - the little real-time evaluation 
of what we've done in the past 20 hours or so and 
what we've got to do leads us to believe probably 
that the third day EVA might be better.

This is Gemini Control Houston. Over the Canary's the crew was 
advised to perform a three foot per second retro-burn. And, please 
advise us of the time of the burn. They have not yet completed the 
burn. When given that instruction, Stafford said "we're about three 
feet away from the monster and we're taking some more pictures." 
The crew is also advised when performing this three foot per second 
retro-burn to please bring up the L-band radar on the ATDA and give 
it a little service check as they move away from the beast. The 
source pressure on ring -A in the ATDA (the target docking adapter), 
is running at 2100, which is a good solid value. Stafford also 
advised that they had aboard plenty of documentary evidence of what 
precisely caused this failure. He did not elaborate on that remark. 

Our best estimate is that approximately 50 pounds of useable propellant 
remain on Gemini 9. This is somewhat less than the flight plan showed. 
We should have at this point in time just a few pounds lees, but its 
probably enough to carry off an extravehicular activity tomorrow. We 
have now the tape conversation with the Canary Station and we'll play

This is Gemini Control Houston. 22 hours, 58 minutes into 
the flight. Three to four minutes from now over the Tananarive 
station we now estimate that Stafford and Cernan will perform the 
three foot per second retrograde burn, and this burn will have the 
effect of lowering the Gemini perigee about one and a half miles 
and will place the spacecraft about eight and a half miles ahead 
of the target vehicle. It will gradually move away from the target 
vehicle at the rate of some eight to eight and a half miles per rev. 
It is a distinct possibility that this is the last time that the 
target vehicle will be seen in view of the low fuel budget. We 
have this brief tape conversation between the crew and remoted 
through the Kano station. We'll play it for you now.

This is Gemini Control Houston. At 23 hours, seven minutes into 
the flight. A very few minutes ago, White Team capsule communicator 
Dick Gordon tagged up with the Gemini 9 crew via Tananarive and we 
were advised that the crew had performed the three foot per second 
separation maneuver that they'd been instructed to do some 20 min- 
utes ago. This maneuver carries them one and a half miles below the 
target vehicle, that's one and a half nautical miles in perigee at 
least, and moves them out in front of the target vehicle some eight 
to eight and a half miles. The crew also was instructed that we want 
to perform a rather extensive accelerometer bias check on the next 
sweep across the United States. The tape from Tananarive has a lot 
of noise on it this morning but we'll play it for you at this time.

This is Gemini Control Houston, 23 hours, 54 minutes into the 
flight. Since we last had a report, we've had contact via 
Carnarvon. Stafford confirmed which thrusters he'd use to 
make his separation maneuver. He also reports that the spacecraft 
radar is on but the ATDA radar is - I'm sorry the reverse of that. 
The spacecraft radar is not on but the ATDA radar is. The 
transponder on top of the ATDA is on. During the course of the 
flight, as perhaps to underscore some earlier coianents from Stafford, 
the people on the ground noticed that Tom appeared to fall asleep 
during the course of the pass. The general plan Is now to run 
silent as Gene Kranz has put it, for the next several revs to give 
the crew a chance to rest. We will however go ahead and perform 
an accelerometer bias check over the states during the upcoming 
pass. For the next several revs it looks very quite. In about 
two and a half hours we expect to start the first of three UHF- 
VHF polarization experiments. These at Hawaii and possibly Antigua.

what we had and the grounds- switching was good and so 
was our onboard backup. We went with that, we kept 
it closed loop and we used a modified first mid-course 
and then we took the backup . The closed loop for the

S/C final mid-course and this switching was exactly 

on with ours. 

HOU Fine. Sounds good. At least we know how to do 

them now, don't we. ? 
S/C Yes. 
HOU Nine, Houston. 

S/C Go ahead. 

HOU Tom, just an overall look here. What we're looking 



at for this afternoon and after you have a couple 

of revs of rest, is picking up some of the expriments. 

The D-lVs and S-ll's. We can update those later 

for you. We'll update them in real-time for you 

to do them after your rest period. We're trying 

to get the EVA tomorrow morning as late as possible 

and still maintaining stateside coverage so we 

can give you a gdod 10 hour rest period tonight before 

EVA prep. 

S/C Roger. That sounds real good. Cm you give us a 

good accurate hack on our propellant quantity from 
the ground readout. I'm showing about 11 percent 
here . 

HOU Standby. You have approximately 50 pounds of fuel 

remaining. 
S/C Rog. 



GEMINI 9A (2) MISSION COMMENTARY, 6/U/66, I'.kh AM TAPE 97 PAGE 1 



HOU Read out electrical. 

S/C Electrical read out. 

HOU Did you get the counts on that quantity readout. 

S/C CA09? 

HOU That is correct. 

S/C Roger . 

Do you want them now? 

HOU Please. 

S/C Okay 



This is Geiiini Control. That probably wraps up the conversation 
for the state- side pass although the spacecraft is only now over 
the east coast of the United States. But we do expect them to go 
ahead with the plan to maintain relative radio silence for the next 
couple of hour to give the crew a chance to cap-nat. The latest 
onboard propellant quantity reading for fuel is an estimate of 50 
pounds and according to the best indications we have now, this is 
enough to go ahead with the fairly limited experiment program for 
the day to complete the EVA sometime tomorrow morning, and continue 
through the planned 70 to 71 hour flight. At 2k hours seven minutes 
into the flight this is Gemini Control Houston.

This is Gemini Control at 2k hours and kO minutes into the flight. 
Gemini 9 now in its l6th revolution, is passing over the Tananarive 
tracking station. We have no voice communication with the space- 
craft and we do not intend to raise the spacecraft at this time. 
Nor at the Carnarvon station which will be next. The ATDA target 
is on its k5 revolution and it is estimated that it will have a 
life time orbit of 31 days. Norad reports the Ei%a»n II second 
stage re-entered over the western Atlantic off the coast of South 
America about 4:26 AM CST today. Our crew is now In an eat and 
rest period that is expected to last for the next two revs or 
approximately three hours. When this period is over, they will 
conduct the D-l4 UHP-VHF polarization experiment, designed to 
measure the electron content of the ionosphere below the spacecraft.

This is Gemini Control Houston at 2k hours, 51 minutes into the mission. 
Within the last few minutes a major flight plan meeting has concluded here in 
the Mission Control Center, with the following results. For the benefit of 
newsmen we think we should pause a moment or two - I think you would want 
to take notes on some of these times that I am going to read to you. We are 
going to cover the activities through approximately the next 2k hours, up 
to about noon tomorrow. Now we'll give you the times in elapsed time of the 
mission, also in Central Standard Time. The first time reference will be 
in Ground Elapsed Time, the second in Central Standard Time. The first item, 
a rest period will continue until 27 hours Elapsed Time, or 10:U0 a.m. Central 
Standard Time. A D-lk Experiment is to be performed at GET of 27 hours, 20 
minutes, or 11:00 a.m. Central Standard Time. A S-ll Experiment is programmed 
for an Elapsed Time of 27 hours and U5 minutes to 28 hours and 25 minutes, 
or in Central Standard Time, from 11:25 to 12:05. A D-lk Experiment is planned 
at 28 hours and 30 minutes, or 12:10 Central Standard Time. Another S-ll is 
scheduled at 29 hours, 15 minutes to 29 hours, 25 minutes, Central Standard 
Time would be 12:55 to 1:35 p.m. A D-lk Experiment is scheduled at 30 hours 
elapsed time, that's l:k0 Central Standard Time. An S-ll Experiment at 30 
hours, U5 minutes to 31 hours 25 minutes, and in Central Standard Time that 
2:25 to 3:05 p.m. D-lk Experiment scheduled at 31 hours, kO minutes, which 
is 3:20 p.m. Central Standard Time. Another B-lk at 33 hours, 20 minutes, 
Elapsed Time, which will be 5 p.m. Houston Time. An eat period is scheduled 
at 33 hours, 30 minutes to 3k hours and 30 minutes which will be 5:10 to 
6:10 p.m. Central Standard Time. The evening sleep period is planned to 
begin at 3^ hours and 30 minutes and last for 10 hours to kk hours and 30 
minutes into the mission, or in Houston time from 6:10 p.m. until U:10 a.m*. 
tomorrow morning. An eat period to follow the sleep period is scheduled 



GEMINI 9A. (2) MISSION COMMENTARY, 6/H/66, 8:31 a.m. Tape 99, Page 2 

kk hours and 30 minutes to hours and 30 minuteB and this will be in Houston 
time from k:10 til 5:10 a.m. EVA preparations are scheduled to begin at U5 
hours and 30 minutes Elapsed Time and extend until U9 hour* and 30 minutes 
Elapsed Time, converted to Houston Time that will be 5tl0 a.m. to 9:10 a. a. 
Our present plan is to open the hatch at 1+9 hours and 30 minutes into the 
flight, this would be toward the end of revolution 31, just off the West 
Coast of the United States, and the time on that would be 9:10 a.m. Now 
an additional factor in the planning - if for some reason the preparation 
goes a little bit slower than usual, or if the unforeseen occurs, and the 
crew needs additional time, before they open the hatch and begin their 
Extravehicular Activity, we can easily slip one revolution and still maintain 
full stateside range tracking during the EVA exercises. Once again, open 
the hatch - planned ground Elapsed Time, U9 hours 30 minutes toward the 
end of revolution 31- The ingress - when Cernan will reenter the spacecraft, 
is presently ticketed for 52 hours elapsed time. This will be in rev 33» 
we do not have a ground corresponding point available Just right mow, »ut we 
will later. Elapsed time of 52 hours in rev 33, the Houston Time of that 
event will be 11:U0 a.m. This is Gemini Control Houston.

This is Gemini Control at 25 hours 10 minutes into our flight. Gemini 
9 is now passing beyond the Australian continent and moving up toward 
the Canton Island tracking station. It is on itsl6th revolution. 
Our Flight Director, Gene Kranz, in this quiet period here where we 
are not raising the spacecraft and allowing the crew to rest presented 
Bill Garvan, our Carnarvon Cap Com, with a little bit of a surprise 
informing him that in the unlikely event that the Houston Mission 
Control center should have a difficulty and be forced to drop out 
of the direction of this flight, during the EVA, he informed Bill 
Garvan that Carnarvon or Hawaii would then have to take over as 
Flight Director. And went over with Garvan the things that he would 
expect Garvan to communicate to the crew and also relay back here to 
Houston. Now the Mission Control Center in Houston is backed up 
to avoid such a difficulty in many ways. However, Flight Director 
Gene Kranz, is attempting to cover all phases and this is a little 
bit of forward thinking. It was a surprise to Bill Garvan and I am 
sure it will be a surprise to the Hawaii spacecraft communicator as 
well. This is Gemini Control. We are 25 hours 12 minutes into our 
flight.

This is Gemini Control at 25 hours and Uo minutes into the 
flight. Gemini 9 is now passing over the stateside tracking 
stations ending its fifteenth revolution, rather, it should be 
beginning its sixteenth very shortly. We have no - we have had 
no communication for the past hour with the crew. Our target is 
now trailing the spacecraft by approximately 18 miles . It ' s orbit 
is about one and one half miles above that of the spacecraft. 
According to our Flight Surgeon, Dr. Berry, the crew is asleep 
and appears to be rather soundly asleep at this time. There are 
no plans to communicate with the crew for approximately another one 
and one half to two hours. This is Gemini Control, 25 hours, kl

This is Gemini Control 26 hours and one minute into the flight. 
Our spacecraft is now in its l6th revolution and is about one 
and one half miles below the target and is trailing by some - the 
target is trailing by some 20 miles. We have had no voice com- 
munications with the spacecraft for the past hour and one half. 
The spacecraft orbit is 157-9 by l6l.O. 157-9 nautical miles by 
161 nautical miles. The target's orbit is l6l.l by 159-3- The 
information we have from our flight surgeon is that the crew is 
asleep and appears to be in a rather sound sleep. The spacecraft 
is now passing over the Ascension Island tracking station and we 
have some quantities to give you concerning the ECS oxygen and 
fuel cell oxygen, the total remaining aboard the spacecraft 
combined total 67 percent. Fuel cell hydrogen 37-6 percent. Our 
flight director estimates that there is enough fuel aboard the 
spacecraft to complete the Gemini 9 mission. This is Gemini Control. 
We will be in a rest period for the crew for approximately another 
one hour and one half. Following the rest period the crew will take 
part in the S-ll and B-lh experiments. This is Gemini Control 
26 hourr and three minutes into the flight.

This is Gemini Control at 26 hours and 10 minutes into the 
flight. Gemini 9 is now in its seventeenth revolution and pass- 
ing over the southern part of Africa. The spacecraft is appro- 
ximately one and one half miles below the target vehicle. The 
target vehicle is trailing by some twenty miles. Here in the 
Mission Control Center, activity is at a very low pitch. Our 
Flight Controllers are preparing for the burst of activity that 
will follow this rest period which will extend for approximately 
another hour and 15 to 30 minutes. And the rest period, of 
course, will be followed by activities connected with the S-ll 
and the D-lk experiments. And so at this time, our Flight 
Controllers are making their preparations to take part in those 
maneuvers . Our Flight Surgeon reports to us that the crew is 
asleep and appear to be sleeping rather soundly. This is 
Gemini Control, 26 hours and 11 minutes into the flight.

This is Mission Control at 26 hours and kO minutes into our flight. 
Gemini 9 has just passed beyond voice range of the Carnarvon track- 
ing station. At that time our spacecraft communicator did raise the 
spacecraft crew and talk to Gene Cernan. He gave Cernan some updated 
times for the D-lk experiment, which will take place at 27:20 over 
Hawaii. That will be at approximately 10:U0 CST. The D-lk experi- 
ment, to do this crew turns a switch on in the spacecraft. This 
extends an antenna, which sends a standard radio frequency to the 
ground station at Hawaii. Stafford will hold the spacecraft steady 
during the pass and the ground stations pick up the radio frequency 
signal emitted by the spacecraft and on the ground they measure the 
electron contents of the ionosphere below the spacecraft by measuring 
the Faraday rotation of electromagnetic transmissions from the space- 
craft. At this time, we will play back the tape voice communication 
between Carnarvon and Gemini 9-

and this was Williams' first time to communicate with an American 
astronaut or any other kind of astronaut. This was his first attempt 
and he did a very good job. This is Gemini Control. Our spacecraft 
has now moved beyond the tracking range of Carnarvon and we are 26

This is Gemini Control , 27 hours into our flight. Gemini 9 is 
passing over the Hawaiian tracking station. We have established 
communications with the crew. Tom Stafford reported to us that 
he is in the midst of his D-lk UHF,VHF polarization experiment. 
In this experiment the flight crew merely turns a switch in the 
spacecraft. This switch extends an antenna which sends a standard 
radio frequency to the ground receiving station at Hawaii. ■ 
Stafford then holds the spacecraft steady during the pass and the 
ground stations pickup the signal and measure the electron content 
of the ionosphere below the spacecraft by measuring what is 
termed the Faraday rotation of electomagnetic transmissions that are 
emitted from the spacecraft. Gemini 9 is now on its 17th revolution 
over the earth and very shortly will begin its l8th revolution. 
This is Gemini Control and at this time we will play back for you

That appears to be all the communication that we will have with 
Gemini 9 as it makes this state-side pass. Gemini 9 is beginning 
its 18 revolution around the earth and as you heard the systems 
aboard the spacecraft looked good to our Flight Controller. They 
feel they may have some trouble with the sensing devices in the 
tank aboard the spacecraft; the fuel cells do look good, the 
accelerator bias check checked out very well. Stafford and Cernan 
have another T)-lk experiment coming up at Antigua which they will 
reach very shortly. This again is the UHF-VHF polarization 
experiment and the activity of the crew is merely to turn the 
switch in the spacecraft, which extends an antenna and automatically 
a standard radio frequency is sent to the ground receiving station 
at Antigua. During the pass, Stafford will hold the spacecraft 
steady. Measurements are made from the ground. This is Gemini 
Control 2? hours and 17 minutes into the flight.

This is Gemini Control at 27 hours and kO minutes into the flight. 
Gemini 9 is now passing over the tracking station at Ascension. 
We have had no voice communication recently since we left Antigua. 
At that time we did get a report that the ground data at 
Antigua on the D-lk experiment looked good. Dick Gordon our 
spacecraft communicator, Astronaut Dick Gordon, who is a member 
of the Gemini 11 Flight Crew with Pete Conrad. Gordon being 
our spacecraft communicator today talking to Gene Cernan in 
Gemini 9 was passing up some updates, time updates for start 
of the S-ll experiments. He gave him several of them. Cernan 
jokingly remarked to Gordon "I see you are looking out for your 
favored S-ll crew." And of course, S-ll is an experiment that 
is programmed for both Gemini 9 and Gemini 11. I think Gene 
Cernan was .jokingly refering to Gordon as having loaded up most 
of the experiments on this Gemini 9 flight. We conducted a 
fuel cell purge and it went good, or it was going good at the 
time we heard a report from Stafford. At this time we will play 
back the taped voice communication between Dick Gordon and Gemini 9

That was voice communication between Gemini 9 and our Control Center 
in Houston. We did follow the Antigua tape with the short message 
that we did receive as the spacecraft passed over the Ascension 
Tracking Station. This is Gemini Control, 27 hours, kk minutes

This is Gemini Control. We are 28 hours into our flight. Gemini 
9 is now on its l8th revolution and is passing over the Indian 
Ocean. Dr. Owen Coons, our Flight Surgeon, has told us that the 
command pilot got two hours of good sleep during that rest period 
we had earlier in the afternoon and the pilot had approximately 
two and one quarter hours of sleep. Both crewmen ate a meal before 
going to sleep. Dr. Coons feels sure that both men will get a 
good night's rest on their next sleep period which begins after 
their next meal at 31 hours ground elapsed time. The D-lU ex- 
periments which we have been conducting over Hawaii and Antigua, 
require Tom Stafford to power up the spacecraft and hold it steady 
as he passes over Hawaii and Antigua. This maneuver requires only 
about one pound of OAMS fuel for each pass. And since we have 
approximately 50 pounds onboard this is entirely adequate to 
complete the Gemini 9 mission without any problems from the fuel 
supply. This is Gemini Control 28 hours one minute into the mission.

Gemini 9 is passing over the Carnarvon, Australia Tracking Station 
range. Some of the little byplay that went on, Bill Garvin, the 
Spacecraft Communicator there asked Tom Stafford is he'd a chance 
to look at the Australian countryside. Tom said "no, we have not, 
we've been to busy." The spacecraft is on its l8th revolution 
around the earth. At this time we will play back the taped voice 
communication between Carnarvon and Gemini 9-

That was taped voice communication between Bill Garvin our Spacecraft 
Communicator at Carnarvon and Gemini 9, Tom Stafford. The only 
eventful item we have coming up in the immediate future on our flight 
plan, as Gemini 9 comes up over Hawaii we will have another D-lh

experiment. This as you may remember the flight crew will turn 
on a switch in the spacecraft to extend an antenna which sends a 
standard radio frequency to the ground receiving station at 
Hawaii. The purpose of the experiment is to measure. the electron 
content of the ionosphere below the spacecraft. This is Gemini 
Control at 28 hours, 13 minutes into the flight.

This is Gemini Control at 28 hours and UO minutes into our mission. 
Gemini 9 is now coming up state side and is within voice range of 
the California tracking station and we have just acquired contact. 
Gemini 9 is in its l8th revolution. Over Hawaii the crew performed 
another D-lh experiment. The D-lk experiment is the measurement of 
the electron content of the ionosphere below the spacecraft. This 
is measured on the ground by a ground station. Coming up on the 
flight plan we have in approximately one hour and a half - about 
three quarters of an hour we have an S-ll experiment. The S-ll ex- 
periment is a photographic experiment. The purpose is to photograph 
the night time air glow and also the sun rise twilight and any 
unusual night phenomena target of opportunity. With Command Pilot 
Tom Stafford aligning the spacecraft small end forward on the 
horizon using a star as a reference point, Pilot Gene Cernan will 
align his camera on that horizon using the same star and he will 
take a series of three pictures of the eastern western and southern 
horizons. He will use a 70 mm Maurer camera with an f -95 lens. 
He takes the pictures with and without filters at various exposures. 
The pilot also photographs the thrusters as they are firing. This 
star is used for reference during this experiment will be A-L-I-O-T-H, 
which is commonly referred to as the North Pole Star, and 
A-C-H-E-R-N-A-R, commonly referred to as the South Pole Star. 
This is Gemini Control, 28 hours h2 minutes into the mission.

Tape 112, Page 1 

This is Gemini Control at 29 hours into our flight. As the 
spacecraft came over the stateside on this last revolution finishing 
up the eighteenth revolution, we had a status report of the space- 
craft systems as they read out on the ground. Our spacecraft com- 
municator Gordon advised the Gemini 9 crew that the PCM tape 
recorder onboard has malfunctioned. At least, we are not able 
to get readouts on the ground and they advised the crew to leave 
it off - turn it off - until EVA. We will not attempt to get any 
data from it until the EVA begins tomorrow, and we will a] so use 
it for reentry. Also, they advised the crew the fuel tank quan- 
tity fuel sensor appears to be inoperable aboard the spacecraft, 
that is, we are getting on the ground good indications of their 
fuel but the sensor which tells the crew how much they have ap- 
pears to be off. The ground says there is no leak in the tanks 
and, therefore, it- must be the sensors. The fuel cells and the 
stacks are bearing the load well. We also passed up a flight 
plan update as follows: At 3?: 59 GET there will be a crew 
status report, a fuel cell purge and a cryogenic quantity read- 
out. At 33:30 they will power down the spacecraft and begin an 
eat period which will last for one hour until 3^:30. Following 
the eat period, at 3^:30, "friey will begin the sleep period for 
ten hours until hk:2,G. The other items on our flight plan were 
to complete the D-lk experiment which we have gone over several 
times. This is the measurement of the electron content of the 
ionosphere below the spacecraft. And at this time the flight 
is proceeding normally. The spacecraft is on its nineteenth 
revolution, has just begun it, is passing over the northern 
part of South America. TTris is Gemini Control. We are now

29 hours, three minutes into the mission and we would like to play- 
back the voiced communication that was made with Gemini 9 as it 
passed over the states. 



HOU Gemini 9, Houston. 

S/c Houston, Gemini 9- 

HOU Roger, Tom. It looks like another good pass 

at Hawaii for B-lk. 
S/C . Roger. 

HOU I have a sequence change to one of your 

S-ll's when you're ready to copy.

HOU Okay, we've been looking at your water down 



here a little bit and E com tells me that 
we are losing a little bit of nitrogen out 
of the gas pressure out of the fuel cell 
regulation system. There is no problem. 
Surgeon says we can stand to drink a little 
more of it. We might start tapping it a little 
bit , if you like . 

S/C Okay. We thought we were doing a pretty good job 

drinking it. We'll go ahead and concentrate on 



HOU 



Okay, we'll watch you. I think, if you take a 
little over a long period of time, it'll be the

Tape 112, Page 3 

best way to look at it. 
S/C Roger. 

HOU And I've got a GNN status here for you if 

you're interested in all that. We've got 
down here it looks like as far as the OAMS 
is concerned, fuel remaining is hd pounds, 
oxidizer remaining is about 78, onboard gage 
is about 11$ and useable fuel gives us about 
82 pounds. This is plenty of OAMS for atti- 
tude control for the rest of the flight plan. 

S/C Okay, real good. 

HOU On the computer . Seems to us down here that 

it's working normally at this time. Acceler- 
ometer bias update was good. It's almost per- 
fect at this time. That start comp problem 
we had after the first rendezvous - during the 
first rendezvous - has not reappeared, and we 
think that problem might either have been in 
the start comp button or in the electronic 
latch internal to the computer. 

S/c Okay, roger. That hasn't shown up since that 

first day. 

HOU Okay, we do have a procedure for you when you 

go to load module 5. We'll play the addresses 
25, 26 and 27 and we think we may be able to

correct it in case it shows up but we'll 
brief you on this when we go to load module 
four . 

S/C Roger. Module four. I thought you said 

five at first. 

HOU I think I did but I meant four. 

S/C Roger. 

HOU Okay. All your GEMC systems look real good. 

Temperatures , pressures and voltages all real 
fine. 

S/C Okay, Dick. You'll still kind of keep word 

with us if we do any activities. We're up 
full rudders in both C-Bands . 

HOU Okay, understand. As far as the E com status 

is concerned, PCM tape recorder has malfunctioned 
in the playback mode. What we'll do with that 
thing is just leave it. It looks like it's 
the beginning of the tape. We'll leave it 
off until just prior to EVA tomorrow morning 
and hope that we might be able to get some AMU 
data on it. 

S/C Roger, real fine. Thank you. 

HOU And your fuel cell quantity tank sensor looks 

like it's gone. Everything else concerning that 
looks okay. We're going to calculate hydrogen 
quantity from amp hours and keep you posted

S/c Okay. The last we saw of it, Dick, we were 

real ^ood. We were way up over oO some per 
cent this morning. 

HOU Okay. It doesn't look to us like there is 

any leak. The system integrity looks good 
and we really think it's the sensor in that 
case. And, it locks like your stacks in the 
sections are sharing the load real well up 
there .

Gemini 9 is now on its 19th revolution and is coming up around 
the Philippine 's very shortly. At this time aboard the spacecraft 
according to our flight plan, Tom Stafford and Gene Cernan should 
be busy with the S-ll experiment. This is a photographic experiment 
designed to photograph the night time airglow and a sunrise twilight 
and any other unusual night phenomena such as the Northern Lights or 
an aberration in the airglow. While Tom Stafford aligns the space- 
craft small end forward on the horizon, using a star as a reference, 
Cernan will align his camera on the horizon using the same star as a

various exposures. The Pilot Cernan will also photograph the thrusters 
that are firing as Tom Stafford maneuvers the spacecraft to the 
various directions. The experimenters are programming four pounds 
of fuel for each S-l experiment. We have approximately 50 pounds 
of fuel on board, sufficient fuel to take us all the way through the 
Gemini 9 mission, with no problems. This is Gemini Control, 29 hours,

them. The RKV, the Rose Knot tracking ship then off the east coast 
of South America reported a visual sighting of the spacecraft on 
this pass, revolution 20, from their deck just shortly after

This is Gemini Control at 31 hours kO minutes into the flight. 
Gemini 9 is over the mid-Pacific, not quite in range of the Hawaii 
station yet. The tracking stations are continuing to stand by 
without attempting to converse with the crew. At Hawaii acquisition 
the crew, Tom Stafford and Gene Cernan will perform another com- 
munications experiment. And we do not intend to disturb them at 
that time. We have very brief contact with them over the CSQ 
and we will play that tape for you now.

Gemini 9 is approaching the west coast of South America and nearing 

the end of its 21st revolution. During the pass over the Hawaii 

tracking station, an updated flight plan was passed to the crew. 

They were reminded to continue drinking water. We won't attempt 

to contact the crew again from any of the tracking stations until 

in the morning. Tom Stafford and Gene Cernan have powered down 

they ' re 

their spacecraft and ' '/ ' -eating right now. They will then go 
into a ten hour sleep period. Prior to this time they will again 
activate the S-12, the micrometeorite experiment and will deactivate 
that immediately upon arising in the morning. This will give the 
experimenter 10 hours bonus on this experiment because of the shift

This is Gemini Control Houston at 1+5 hours 10 minutes into the flight. 

The crew was awakened some 20 minutes ago as we began the state side 

pass, and Stafford greeted us with a very chipper, "hello down there". 

He noted that during the night, the cabin seemed to get a. little cold, 

perhaps 10 degrees cooler than they've been running; here on the ground 

we had anticipated that. The problem seemed to be that we're building up, 

as much as we did in the flight of Gemini 7, a little excess fuel, fuel 

cell product water. The fuel cell product water empenges- on the drinking 

water through a series of bladders, so the solution is worked out to 

dump some of the drinking water, and this was carried out, we dumped on 

the order of a pound to pound and a half of drinking water by directly 

connecting the drinking water nossle,the squirt gun, to the uriceptacle 

and by placing certain switches to by-pass the radiator to dump the water 

directly over board through the water boiler. As I say this procedure 

was carried out during the state side pass. The crew has tagged up 

on their start of their EVA preparations which will begin during this 

revolution. We also to get a crew status report in some detail, they will 

get a planned landing area up-date at Canary, which acquisition circled they're 

entering now at 1+6 hours and 28 minutes they are to receive a go, no go, 

for a 1+6-1 flight or the completion of the planned mission. At 1+8 hours

leading to the extravehicular activity. The sunrise time for the 31st

This is Gemini Control. That concludes the stateside pass. We got more 
information a few minutes later from the Canary station regarding the crew 
status. Stafford reports they have drunk since the last reporting period 
some kO ounces of water. They've had one meal apiece. He described their 
sleep last night -- each man about four hours of solid sleep -- six to eight 
hours of dozing sleep. They sound rested. Here is the Canary tape.

This is Gemini Control, Houston at U5 hours, Uo minutes into the flight. 
Several items as far as consumption history here for the notes, we've had no 
further contact with the spacecraft since Canary. It is now crossing the Indian 
Ocean. 

We have approximately 1200 amp hours remaining in the fuel cells . They 
are continuing to produce electricity at a very good rate. Total of about 
50 percent of the capacity remaining. Cabin pressure has held at a very steady 
5.1 PSI since the begirriing of the mission. Virtually no change) .noted in that. 

The spacecraft orbit presently shows 157.3 miles by l6l.l Biles, the 
target vehicle is in an orbit 158.6 miles by 1. excuse it...l60.7 miles. 
During the extravehicular exercise, the target will be approximately 1U5 miles 
behind the spacecraft. Earlier Stafford was advised that the weather was 
marginal in the 30 dash one area, he was also told that it was marginal in the 
dash three areas. Since that report went up, we've had new information from 
ships in the area. And they advise that the weather is improving very nicely 
and they see no/p e ^r e problem should a landing be necessary in those areas. 
We anticipate no need for a landing in those areas, but the area is improving 
in the prime recovery area in the Atlantic . 

Propellant quantity. . .OAMS propellant, we show some 90. . .85 pounds of 
propellant, still available for this mission. . .approximately 50 pounds of fuel 
and 80 pounds of oxidizer and a plan that would give us about 85 pounds of

put one question to them, he said if you don't have a full mouth of food, 
he'd like to know the on-board propellent quantity, and Tom Stafford with 
about a half mouth full of food replied 7 percent, which agrees with the 
earlier number which we passed on to you about 85 pounds of usable propellent

This is Gemini Control Houston, U6 hours, 10 minutes into the flight. 
The weather this morning goes like this. This is the forecast for the 
next 2k hours, or in other words, up to end of mission. In the mid- 
Pacific landing zone, centered about 300 miles northeast of Honolulu, 
partly cloudy skies, winds westerly 10 to 15 knots and seas three to 
four feet. In the western Pacific landing zone, centered 700 miles 
south by soutwest of Tokyo, mostly cloudy skies with scattered showers, 
with winds southwesterly 15 to 20 knots, and seas five to six feet. In 
the eastern Atlantic zone, centered 300 miles west of the Cape Verde 
Islands, partly cloudy skies, winds northeasterly about 15 knots and 
seas four feet. In the western Atlantic, end of mission landing zone 
near 75 degrees west longitude, mostly cloudy skies with scattered 
showers, winds easterly at 15 to 18 knots and seas four to five feet. 
That shower activity reportedly is moving to the northeast and probably 
will clear out of the area within the next 2h hours. No new contacts 
with Gemini 9 since we left Carnarvon, we are in the Canton Island area. 
The crew is still eating breakfast, we don't expect additional contact 
until they reach the states, which will occur in some 12 to 13 minutes. 
This is Gemini Control Houston.

GEMINI 9a(2) MISSION COMMENTARY , 6/5/66, 6:20 AM TAPE ikl PAGE 1 
This is Gemini Control Houston k6 hours kO minutes into the 
flight. The crew is now well along in their very detailed check 
leading up to the EVA exercise. This check lists runs, to give 
you some idea of the depth of it, it runs 11 single spaced pages 
in the flight plan. Hundreds of items involved. Switch settings 
are specified for every system onboard plus a great deal of 
equipment, special equipment involvment for Gene Cernan. During 
the recent pass across the states the spacecraft now slightly 
east of Bermuda, the crew was given a go for a k6-l, in other 
words the full 72 hour mission. That report brought back a 
very cheery, "Thank you" from Cernan. Last night the S-12 ex- 
periment, the emulsion pack, which is used to collect micro- 
meteorites was exposed for another 10 hours. The first night 
out the exposure time on S-12 was eight hours and kO minutes. 
So the 10 hours is an added dividend having to do with the 
postponement of EVA, of course. We have now a very brief tape 
of the conversation across the United States, there was not very 
much chatter because Tom Stafford indicated they were busy with 
their EVA preparations. They postponed certain discussions 
until later in this pass. Here is the conversation.

have the Y-connectors in place now on the chest pack and Gene 
Cernan probably is hooking up the umbilical just about now. 
Relatively little communication between the ground and the space-

The spacecraft's over the Tananarive station. No new contact since we 
last heard from the crew via Kano. EVA preparations continuing. We 
are getting a little talk now. A little static in the background. 
Standby one, please. Tom Stafford advised he'd been running in platform 
mode, and he noticed a little roll developing. It's completely under 
control. He's back in 000 rates. He just wanted to advise us. Our flight 
plan is completely clear with - except for the item of EVA prep which con- 
tinues to run. We expect the sunrise on that 31st rev to occur ^9 hours, 
26 minutes in elapsed time. A little more than two hours from now, and 
that's about the time that the hatch would open and we'd start ingress.

This is Gemini Control Houston. Fourty- seven hours 18 minutes 
into the flight. And during the course of the Tananarive pass 
we learned from Tom Stafford, that he was having a problem with 
his number three thruster. This is a roll thruster. He noted 
a rate building up in roll. It is co-incidental I am sure, but 
this is precisely the same area where Neil Armstrong developed 
trouble during his flight with another thruster and of course 
the rates built up much more severely. In any case he has 
identified the problem in number three thruster. He shut it 
down and he will compensate for it by using other modes of 
thrusters to perform the various maneuvers. We do not expect 
to have any effect on the EVA exercise, at this time. The 
problem will be looked at very carefully over Carnarvon and 
additional judgments may be coming along> but right now we are 
still moving right ahead with our EVA preparations. Here is the 
voice tape of the Tananarive pass.

TAPE 1U5, PAGE 1 



This is Gemini Control Houston, k r [ hours, 31 minutes into the 
flight. As we noted over Tananarive, Tom Stafford reported some 
trouble with his number three thruster. He went through a varied 
detail check of his control modes crossing the Indian Ocean. When 
we picked him up at Carnarvon a few minutes ago, he and the 
ground seemed to be pretty well frustrated by the problem. He 
reported that the thruster - the inoperation of thruster 
number three was putting him into a roll rate of as much as 20 
to 30 degrees per second, when he energized his second in-plat 
or the platform mode. This frustration continued for some seconds 
and then we have to chalk up a big plus sign for our Guidance 
Navigation Control Officer, Gerald Griffin. In a very quiet voice 
he asked him to check his circuit breakers on the scanner on-the 
horizon scanner circuit breaker. Tom Stafford checked this circuit 
breaker and found he had accidently knocked it off apparently during 
the EVA preparations. He put the circuit breaker back on and 
ever/thing settled down immediately. He has the number three thruster 
back, all modes are operating just as they have been throughout the 
flight. The knocking off of that circuit breaker completely explains 
the difficulty encountered in the control mode. We say again he 
has now - we have now fully explained and understand the control 
problems that Tom reported over Tananarive. This taped conversation 
over the Carnarvon Station will explain it to you. Here it is. 
S/C Aft is steering away - repeat away from the roll. 

The pitch is - we put the platform to zero, zero, 
zero. It's like being in a l80 at R break. You know 

the way the needles go

S/C My yaw needle breaks the platform right here/T nave 

to when the pitch needle is up I have to pitch down 
to bring it in. When the roll needle is to the 
right I have to roll left. Looks like that logic 
is reversed from the roll and pitch. 

CRO Okay standby.

give the same results.

This is Gemini Control Houston at U7 hours , 50 minutes into 
the flight. We have a brief exchange between Gemini 9 and the 
Houston Cap Com via the Canton station. We'll play that for you 
first then we'll come back and note some of the events that are 
planned to take place during the EVA exercise. We have had to 
develop a special flight plan which has appeared only during the 
last hour or two here in the Control Center. We'll run through 
it for you noting some of the highlights we'll be watching for, 
but first here is the Canton tape .

And this is Gemini Control Houston. The spacecraft now on the 
outside edge of the Hawaii acquisition area. We don't expect any 
additional conversation via Hawaii. Sunrise again for EVA a criti- 
cal item is noted at k9 hours, 26 minutes. At ij-9 the hatch is to 
be opened and Gene will stand up at that time. The first item 
calls for Gene to jettison and throw overboard some of the un- 
necessary pouches that contain various pieces of EVA gear. He 
will first retrieve the S-12 experiment, the nuclear emulsion 
package exposed on the adapter end of the spacecraft , hand it in

to Tom Stafford. He will then deploy the handrail along the 
adapter and set up his 16 mm movie camera with a wide angle lens. 
He'll proceed to the front of the spacecraft. This event to occur 
at about U9 hours, 30 minutes elapsed time. He'll attach a rear 
view mirror to the docking bar , the indexing bar , at the front of 
the spacecraft. He will then do a umbilical and a Velcro evalua- 
tion, before returning to the cabin area. He will hand the camera 
in to Tom Stafford, who will change the film on the EVA movie 
camera which will be re-installed in its place on the adapter 
area. Meanwhile, the EVA lights will be lighted and at 50 hours 
elapsed time the flight plan calls for the handrails and the foot 
rails to be extended in the adapter area. Within a minute or two 
Gene Cernan should be in the adapter. He will inspect the entire 
area, along the way he'll take a good look at the spacecraft. He 
will make sure that the bars are in place , firmly in place , the 
handrails and the foot rails . At 5° hours and 20 minutes he will 
physically enter the adapter and take a pressure reading on his 
peroxide levels in the Astronaut Maneuvering Unit. At an elapsed 
time of 50 hours and 25 minutes he is expected to actually don 
or put on, get into, the AMU - strap it around him. He will 
immediately proceed with the light warning check, testing the 
audio signals and the various lights which will serve to him 
as audio and visual cues to any untoward happening. At 50 hours 
and 30 minutes, 35 minutes, he's to give Tom Stafford an indica- 
tion before undocking and uncoupling the AMU from the adapter

area. At 50 hours, kO minutes into the flight, this would be about 
80 minutes into the EVA portion of the flight, the AMU would be un- 
docked. Correction - that AMU deployment would take place at 50 
hours and 50 minutes into the flight. At which point he would 
move out away from the adapter a few feet and run a check on all 
of his thrusters, translating up, down, forward, aft, roll, pitch 
and yaw. At 51 hours, he would attach the 100 foot tether to the 
?5 foot umbilical, and give us a status check on the AMU. He would 
then proceed forward along the spacecraft. This occurring, approxi' 
mately, at the end of rev 32 by which time the elapsed time would 
be 51 hours, 10 minutes. 51 hours 15 minutes, call it. At which 
point he would be over the Texas station. After a through look at 
the forward end of the spacecraft and attaching his tether to a 
holder in the area of the docking bar, he would move out in front 
of the spacecraft and perform a figure four maneuver, wherein he 
moves some 80 feet directly forward of the spacecraft. At the 
80 foot point he would stop his movement and move in a left direc- 
tion for, approximately, 80 feet. And then after completing that 
he would move off for the ^5 degree angle again , a flat plane 
forward of the spacecraft, for some 75 to 80 feet, at which point 
he should be in the order of a 120 or 125 feet in front of the 
spacecraft. Then he would make a turn and come straight back 
toward the spacecraft, thereby completing a figure four or perhaps 
it might better be described as apennant if you traced it on a 
piece of paper- A pennant with the point to the left. At 51 hours

30 minutes he is to perform a status check and at which point he 
would be 110 feet out . His mode on the AMU would be a manual 
mode. He would turn off the automatic system. At 51 hours, ho 
minutes he would be back on the umbilical at which point he would 
jettison the AMU tether, plugging back in to the spacecraft oxygen 
supply. Immediately after that he will jettison the AMU itself, 
pushing it down and away. Sunset at that time should occur at, 
rougly, 51 hours and 1+5 minutes. And it will be approximately 
that time that the hatch will be fully opened again. All during 
this period, during most of this period, the hatch will be only 
open two to three inches thereby protecting the plastic rubber 
seal on the inner face of the hatch. Cernan at this point would 
stand in the hatch and take some dim light photographic pictures 
of the airglow and other phenomena. And his last EVA act will 
be to retrieve a 16 mm camera mounted directly behind him. He 
would enter the hatch, according to our present plans, shortly 
before 52 hours elapsed time in the mission. The total EVA time 
budgeted is 160 minutes according to his plan. Call it 156 min- 
utes. We've just come into

moves across the states. 

Gemini Control here during this period there is no conversation. 
We have some additional information regarding that scanner heater 
circuit breaker. We simply identified it as the scanner circuit 
breaker back when we were over Carnarvon. The item that was giving 
us trouble was apparently knocked off during the EVA preparations. 
We credited Jerry Griffin, our guidance navigation control officer 
here with the solution to that problem. Jerry now passes the 
credit on to his staff support room. And specifically to James 



who came up with the solution and passed it to Griffin, the 
controller, who in turn gave it to the flight director and it 
was then relayed to the crew. Mr. Walker has been congratulated

Stafford reported on over Tananarive pass. It has been 
calculated that on the order of three pounds of fuel has

This is Gemini Control H< 'ustun at UH hours, U3 minuter, into the 
flight. Tananarive is within the acquisition area for the space- 
craft at this time. We expect some conversation remoted from the 
Tananarive Station with Neil Armstrong here in Houston. Meanwhile 
we last heard from Tom Stafford via the Kano Station. He reported 
they were running a little ahead of schedule on their EVA prep- 
arations checklist. He reported everything was going very nicely. 
He also said they were drinking lots of water as per the instruction 
of the Houston Surgeon. Cur Guidance Navigation Control Officer 
here advises that we should go into the EVA operation with 
approximately pounds of fueL remaining or a total propellant 
remaining of 76 pounds. More than adequate for the EVA and the 
remainder of the mission. We are also pulling presently about 
36 amps on the electrical system. This will go up a little bit 
higher as we move into the EVA, presently showing about 36 amps.

and tones available to Gene Cerium on his extravehicular equipment. 

He has six status Lights which give him warning of potential or 

actual problems. They function much like the warning lights on 

a car. One - the first item is a hydrogen peroxide light, which 

would erne on should the pressure in the hydrogen peroxide or 

the gas system in the AMU fall below 38O pounds per square inch, 

within plus or minus 30 pounds per square inch of that value, 

380. The hydrogen peroxide presently which has not yet been activated 

is reading a very constant 85 pounds per square inch which is 

the expected value and it also shows 71 degrees in temperature. 

A second light concerning the peroxide quantity would come on 

should the quantity drop below thirty (30) percent. He has on 

board 26 pounds of hydrogen peroxide fuel. He also has a gage - 

all these gages and lights are on the upper part of the chest 

pack fully in view as he moves about outside the spacecraft. In 

every case when anyone of these little white lights comes on he 

also gets a 1700 cycle per second tone. A beeping tone as an 

added reminder. If he decides its not a real problem he can turn 

the tone down to the point that its inaudible but he cannot turn 

off the light. It would remain on and continue - enable him to 

continue to check it. Tom Stafford would also get that tone in 

the spacecraft. It would be broadcast through the little transceiver 

available to Gene with which Gene will communicate with Tom Stafford 

while he's outside on the tether. A third light will be following 

the oxygen supply pressure. When the pressure in the bottle on the 

AMU drops below 800 pounds per square inch within plus or minus 60 



GEMINI 9A (2) MISSION COMMENTARY , 6/5/66, 8:23 a.m. 



TAPE ll+8, PAGE 5 



it will also - the same light would be activated should the temperature 
of the oxygen fall - move plus or minus 5 degrees. In a fourth 
light will monitor the reaction control system in the AMU and would 
go to white should the RCS power drop below 13 volts. This is 
a 28 volt system in the AMU. It would also be activated should 
Cernan be operating in a stabilized mode and in the event that a 
thruster would fire more than 7 percent of the time. Thus a 
guard against a stuck thruster. A fifth light would come on if 
there is a problem of flow in the emergency oxygen bottle located 
in the chest pack.- He's got a thirty minute supply of oxygen in 
the chest pack which under normal circumstances would not have to be 
access for other than checks. In the AMU he has a 7-3 pound supply 
of oxygen which is more than an hour's supply, something in the order 
of seventy minutes. A sixth light will indicate a drop in suit 
pressure. Suit pressure is normal during the EVA,. EVA exercise 
at 3.7 pounds per square inch. A light would come on should that 
pressure drop below 3>3 pounds per square inch, -within plus or 
minus .1 pound. There is a relieve valve in the suit, should the 
pressure build up over 4.5 pounds per square inch. That covers 
the six primary warning devices that Gene has and at this time I 
believe we have a taped conversation of the Tananarive Station and 
we will play it for you now.

the Carnarvon station to go ahead when they acquire in some two to 
three minutes to give the crew a go for depressurization. I repeat, 
he told Carnarvon to give the crew a go for depressurization. This 
event is to occur over the Carnarvon station, and the actual depres- 
surization would take place between Canton and Hawaii - closer to

Okay, good, are you coming? 

Okay, I'm trying to get them out, Tom. 

All rightee. 

It's a long way back to that hand rail. 
Is it? 

Okay, keep it holding, Colonel. 
Okay, I've got you. 

Pretty much of a bear to get at this thing be-

This is Gemini. Control Houston. Gene Cernan is going about his 
duties in a very business-like way. It sounded to us here on 
the ground the communication a little choppy to start with. 
It improved as we moved through the center of the Hawaii circle 
and we lost the acquisition about a minute ago. We should 
pick them again in about two minutes via California. At 1+9 
hours and 26 minutes elapsed time, Gene did retrieve the S-12 
micrometeorite impact emulsion dish. He also deployed the 
hand rail about two minutes later, and he noted that it was quite 
a distance back to the hand rail. He seemed to have a little 
trouble setting up his EVA l6 mm camera and now we have re- 
acquired via California. Let's go back to the spacecraft,

about ready to change the camera film. We're on 
the far eastern edge of the Bermuda acquisition 
zone which overlaps with Antigua. If we get 
some additional conversation we'll go right back 
there. Several times we've heard Cernan refer 
to the fact that he had no torqueing or roll 
ability with the umbilical. Of course he does 
not have a handheld maneuvering gun as did Ed 
White. He does note a tendency to float upwards 
above the spacecraft with the umbilical, which

This is Gemini Control in Houston. Just as we bagan to talk Antigua 
lost the signal with the spacecraft. Ascension will pick it up 
at 50 hours and one minute into the flight. We presently read 
i+9 hours, 57 minutes. The crew noted that they had changed the 
film in the EVA camera. Stafford noted at the end of that con- 
versation that he had jettisoned the thermal curtain which protects 
the AMU. device in the after-end of the adapter. He's also illuminated 
the EVA lights. They are now, or in about ?0 minutes, will be 
moving into a night area. The flight plan calles for Stafford 
to extend the hand rails arid the foot bar in the adapter area 
which Gene will be braced against when he dons his astronaut

maneuvering unit. Meanwhile Cernan is to move to the adapter area 
and inspect the area generally and look at any strap hangings 
that might be part of the separation from their Titan booster. 
He didn't note any earlier. We had a very brief report there. 
He didn't see a lot of straps as we saw on the Gemini 6 spacecraft. 
He will test the bars - the hand rails fend the foot rails - to 
make sure they are securely locked in place, and he is to enter 
the adapter at 50 hours and 20 minutes into the flight or right 
about sunset with the spacecraft over Tananarive. Once in the 
adapter the first check he will make with the AMU is to check 
the pressure on the hydrogen peroxide reading and he will check 
this with Stafford who also has a cockpit read-out. Here on 
the ground the Flight Controllers are looking at their various 
readings and they are all giving very favorable reports to the 
Flight Director. The doctor notes that Gene Cernan 's heart 
rate toward the end of the stateside pass had dropped down to 
the order of 125 beats per second, an indication that he is 
adapting very nicely to space walking.

This is Gemini Control Houston. Communications are, as I am sure 
you are Doting garbled. We can catch about every third or fourth 
word. We did gather that Gene was moving to the ar.aa of the adapter 
to inspect the separation plane between the adapter and the second 
stage of the Titan. Once he passes the adapter edge he will make 



GEMINI 9k (2) MISSION COMMENTARY, 6/5/66, 9:UO a.m. Tape 155, Page h 

a very careful visual inspection of the AMU, in- 
suring that the bars are in place, the foot rails 
and the hand rails and he will check his reaction 
control system handles very carefully on the AMU 
before moving on with the flight plan. We pre- 
sently read 50 hours and 10 minutes. The crew has 
consistently stayed right with the flight plan as 
written. We expect sunset to occur in the Pretoria 
area at 50 hours and 16 minutes into the flight 
at which point Cernan is to enter the adapter area. 
Our next acquisition is slated for 50 hours and 13 
minutes through Pretoria, South Africa and followed 
by an acquisition at Tananarive at 50 hours 18 
minutes. It is unlikely that we would have any 
voice communication coming back from Pretoria. I 
think it will be monitor, a ground monitor only 
situation. This is Gemini Control Houston.

This is Gemini Control Houston. During this interlude between 
stations let's check the temperatures and pressures existing in these 
two suits. In Stafford's suit the pressure at last reading which 
was Cape down range reading shows 3-67 pounds per square inch. In 
the right suit, the EVA - Cernan's suit - the temperature is running 
5U.7 degrees. The pressure 3.73 psi. Meanwhile, the AMU hydrogen 
peroxide the gas fuel, which has not yet been activated - the system 
still is inactive until Tom Stafford turns the switch in the cockpit ■ 
that reading shows a very steady 85 which it has run since the begin- 
ning of the flight. The peroxide temperature is 71 degrees. This 
is Gemini Control Houston. 



This is Gemini Control Houston. The Tananarive communicator has 
just been advised that his station is remoted. We expect some contact 
here momentarily. We presently show 50 hours, 18 minutes into the 
flight. There's Tananarive coming in, almost right on schedule. 
Tananarive confirms acquisition. The signal from Tananarive is even 

choppier than that from Ascension. It is completley unreadable. There 
is communication coming, however. Garble.

did manage to decipher here that Stafford reported he was using the 
high rate of<oxygen flow in order to keep the pilot cool. The tempera- 
ture on Gene Cernan. l s suit is still 5^.7, his pressure 3-73. We had 
expected to use the 02 high rate, the oxygen high rate system during 
this period and it should be cooling off just about as they go through 
their sunset. Cernan, outside the spacecraft, will see a drop in tempera- 
ture on the order of 3 to U00 degrees as he goes from a sunless to a 
black night. The onboard oxygen supply shows hG% remaining and they 
still have an option. here, if they'd like, they can open a cross feed 
valve and bring in — introduce — the fuel cell oxygen supplyi, making 
it common to both' the breathing oxygen as well as the oxygen required 
to operate the fuel cell. This request was passed on to Houston -- 
the suggestion that perhaps they should go to the cross feed valve and 
the answer went back in the negative. We would like to keep them on the 
onboard supply oxygen for this time. Carnarvon will the next station to 
acquire. That acquis ifciofcoto come at 50 hours, 3^ minutes into the flight. 
We're presently reading 50, hours, 29 minutes into the flight. Acoording...

....and according to our flight plan Gene Cernan should be putting 

on, getting into the AMU, strapping it about his waist at .just 

about this time. The - once he has gotten into it he will go 

through a light and wiring test - light and signal warning test 

excuse me. Once that is completed he will take a two to three 

minute rest. Following the rest period he will go through 

a visual acuity check to see what kind of stars he can see through 

his - with his EVA visor - his special gold plated visor in the 

up position and the down position. He is due to give a rather 

comp]ete pilot status report at 5 hours and 3^ minutes to Stafford. 

By Carnarvon they will be ready to go for the undocking of the 

Astronaut Maneuvering Unit. That event to take place about 

5 hours and - 50 hours and 38 minutes into the flight - at

This is Gemini Control Houston. Gemini 9 has tagged up with the 
Carnarvon Station. The ECS quantity is showing k2 percent which 
on the nominal. Tom Stafford reports that Cernan is encountering 
some fogging up of the visor. They are keeping the high rate 
02 flowing in order to reduce this fogging. Cernan also noticed 
his pressure reading gage on his arm is fogging slightly also. 
They report their having a little more difficulty then expected 
in deploying the attitude control arms on the AMU. Cernan' b 
words were "they didn't work out - their not working out just 
as they did in the simulations . " We have some conversation ,

160. ■ At loss of signal from that station at that station he 

read 135 • He said the command pilot has been running a very 

steady 85 as a heart beat and he pronounced the two of them in 

good shape. Cernan is continuing to hook up the various connections 

that he must make on the AMU. At last report he was plugging in 

the electrical system. We're presently showing here 50 hours,

and made the preliminary checks on those. The next sunrise is 
set for 50 hours, 50 minutes into the flight. It will occur 
before the crew reaches Hawaii . If they -ire still right on the 
flight plan as they have been to date, they will have deployed 
the Astronaut Maneuvering Unit before we acquire at the Hawaii 
Station. That acquisition is to come at 50 hours, 59 minutes 
into the flight. A ship, the range tracker slightly west and 
south of Hawaii should get some communication from the pair 
however, about three minutes earlier at 50 hours, 56 minutes into 
the flight. We're a little puzzled by Tom Stafford's repeated 
concern over the oxygen quantity. We show this as exactly 
nominal following the flight plan curve. I'm sure we'll cover 
this in more detail over Hawaii and over the next sweep across 
the stites. At 50 hours, 1+9 minutes into the flight this is

This is Gemini Control Houston, 50 hours, 56 minutes into 
the flight. Gene Cernan now has been extra-vehicular for slightly 
more than an hour and a half. We put it at about 9^ minutes since 
hatch opening. At one point during the Carnarvon pass, he brought 
several of us up short when he reported, I've got news for you. 
Our oxygen quantity reading is zero. And then he quickly noted he 
had not energized the switch on the side of the AMU which makes 
the oxygen flow. He did have some difficulty with the switch but 
once he did get it switched, it flowed very nicely and it showed 
the proper reading. The people in one of the back rooms here in 
the Mission Control Center are monitoring very carefully each of 
the extra- vehicular systems, are entirely satisfied with their 
operation to date. There is a question about the fogging that 
Gene mentions that, perhaps, he did not have his EVA visor down 
over his normal suit visor which might account for some of it. 
As we come up on another sunrise we're quite certain he will have 
his extra-vehicular visor in place. The Range Tracker is standing 
by for any communication that may come along now. And, we're 
listening closely for that. Apparently, we will not have com- 
munication through the Range Tracker. The Hawaii station should 
acquire about one minute from now. We'll come back then. This is

was a period there during Hawaii when he was trying to transmit over the 
AMU transmitter and of course, these transmissions go only to 8tafford

his voice and Sf Stafford only transmission. This is Gemini Control

visual definition that he could see through a little spot where his 
nose was but he could not see through where his eyes are. But, 
apparently, as to demonstrate that his vision wasn't completely

Stafford Ok 

This is Gemini Control Houston. Stafford has recommended that 
Cernan return to the spacecraft before sunset. He has planned to 
return to the hatch area about 51 hours and U5 minutes into the mission 
and then take some sunset and darkness photographs. However, due to 



GEMINI 9A (2) MISSION COMMENTARY, 5/6/66, 10:58 a.m. Tape l63, Page 2 

the fogging condition which still obscures about kO per cent of Gene's 
visor the decision has been made by Stafford, concurred here on the 
ground; that Gene return to the spacecraft and the hatch be closed 
fairly shortly. We still don't have a complete explanation for the 
fogging. We do know that while in the AMU area, in the adapter section, 
suddenly the temperature rose - Cernan reported he got quite warm and 
when he did, the fogging condition nearly obscured his visor area - it 
then became retarded - he could see more, but it still persisted and 
when he left the adapter area it was still 75 to 80 per cent obacurbed. 
It's now down on the order of kO to 50 per cent. The two of them now 
are working. . .stowing the umbilical, getting Gene back. Let's go back 
and listen to this conversation. 



Cernan ...(garbled) f orward .... there you go.

think I'm getting more fogged up now.

This is Gemini Control Houston. While Stafford and Cernan are 
maneuvering as Gene returns to the cockpit we do know that Cernan has 
recovered the Extravehicular Activity Camera. He has passed that in 
to Stafford and its been stowed at 51 hours and 26 minutes now. The 
hatch has been opened for two hours and k minutes and as he approached 
the hatch Stafford again reported, based on a relay from Gene Cernan

that he was encountering even more fogging which reinforces the wisdom 
of the decision to conclude the activity without attempting the AMU. 
Meanwhile here in the Control Center we are working on a plan to separate 
the Astronaut Maneuvering Unit from the adapter section. It will not 
jettison or move off by itself. The spacecraft must perform a translation 
maneuver to move out in a way from the AMU. At 51 hours and 26 minutes

signal at the Antigua Station - actually we're well beyond its 
range now. The next firm communication should come in about five 
minutes from the Rose Knot Victor. That acquisition is scheduled 
for 51 hours, 3U minutes. Crew is still apparently working - we 
just hear bits and pieces back and forth as they concentrate on 
this ingress procedure. We'll standby and monitor that conversation.

This is Gemini Control Houston at 50 hours, 31 minutes into the 
flight. One minute ago at 50 hours, 30 minutes into the flight, 
Stafford reported "we have the hatch locked." They now are preparing 
to repressurize the cabin and will settle down for the remainder 
of this flight. We are still receiving some communication. It's 
a bit scratchy, at the far end of the Antigua area. We'll standby. 
This is Gemini Control.

This is Gemini Control Houston, 51 hours, 38 minutes into the flight. 
The Rose Knot Victor has acquired, there is a high back ground noise, 
something like a soaring airplane in the background but we could make 
out that the crew is going through the repressurization cycle. At last 
reading, the pressure in the cabin had built up to 3. 13 . They will con- 
tinue to build now until something over 5 pounds. Stafford just noted 
they're up to if pounds. During the ingress procuedure, Cernan reported 
that his visor again became completely fogged. We have no sound explana- 
tion for this. A guess or two coming from one of our staff support rooms 

in the back is perhaps that the suit did not take enough moisture out 
all of 

in view of/Cernan's activities. Perhaps the suit failed to take away 
enough of the moisture which is one guess at what could cause the fogging. 
Stafford gave a quick summary on the EVA exercise by simply saying, "I 
think we've learned a lot." We have this conversation, we'll play it 



for you now.

HOU Houston copies. 

This is Gemini Control in Houston. Although it might have been 
hard to decipher, we did deduce that the cabin pressure was up to 5«3 
which is a normal cabin pressure. And apparently, things are settling 
down very nicely. The flight plan; shows that for the next k5 minutes 
to an hour the crew will be engaged in stowing their chestpacks, stowing 
the umbilical, doing all of the post EVA functions. They are not quite 
as extensive as the four hour prep period before EVA but, more than an 
hour has been allotted here on the board for those kind of functions . 
Exactly one hour, as a matter of fact. We also do not yet have a precise 
time on when the AMU will be separated. We suspect that it will come 
along this afternoon a little later. It will involve both breaking loose 
the AMU from its fixed points at the adapter then the spacecraft will 
accelerate away from it. At 51 hours and U7 minutes into the flight, 
this is Gemini Control.

This Gemini Control Houston 52 hours 11 minutes into the !'! ight. 
Carnarvon should acquire the spacecraft in approximately one rrinute. 
It will not be a long duration pass as the spacecraft is winging wide 
high and north and west of the Australia continents . Perhaps 30 seconds 
to 6o seconds communications at best. They have not yet acquired the 
signal. We expect fairly full discussion of the EVA maneuver over the 
Hawaii station and at more length during the stateside pass. This 
pass will take us down the West Coast of Mexico through the heart of 
South America. In the meantime we have checked with our ECCOM position 
here - electrical and environmental and communications - and he's passed 
on to us some times that he noted in his book - these may be revised 
later depending upon spacecraft records, onboard tapes, and the like. 
But his official logs showed the hatch opened at U9 hours, 21 minutes 
and 58 seconds elapsed time. That was U9 hours, 21 minutes, and 58 
seconds - hatch open. Cernan was reported standing in his seat at 1+9 
hours, 2h minutes and 7 secondr. into the flight. Stafford reported 
the hatch was locked in place at 51 hours, 31 minutes, 00 seconds, 51 
hours, 31 minutes - hatch' locked in place and one minute later, 51 hours 
32 seconds they reported the cabin was being repressurized . We still 
have no planned activities on the board this afternoon. We still expect 
that we will jettison the AMU in perhaps an hour and a half later, an 
hour to an hour and a half from now and perhaps additional experiments 
will be performed although we have no plan, as I say, at this time. 

At 52 hours, 13 minutes into the mission, this is Gemini Control. I 
am reminded we have a short and almost untelligible tape from the 
Tananarive Station, we'll play that for you now.

This is Gemini Control, 53 hours, 10 minutes into the flight. 
This orbit shaping maneuver that you heard Cap Com Neil Armstrong 
pass up to Tom Stafford is a maneuver that is designed to pull the 
apogee down about 10 to 12 miles. This will make retrofire 
dispersion less sensitive and it will allow better control during 
the reentry. The VW tank that you heard them talking about is an 
auxiliary fuel tank, holds 12 pounds of fuel. If he starts to get 
into this tank during the burn he will quit burning at that time.

crew was awake when they came over the hill at Carnarvon station. A sleepy 
sounding Tom Stafford report .. .responded to the spacecraft communicator's call 
and the spacecraft communicator reported that the spacecraft was "GO" on the 
ground. The crew of Gemini 9 conducted a scheduled fuel cell purge during the 
Carnarvon pass and began their power up- check list. They also got a flight 
plan update of items to be conducted, such as the crew status report at Canary 
Islands and began stowing equipment, prior to retrofire. They also have an 
eat period scheduled during this time. We have had a change of pace in the 
music being piped in on one of the inactive loops here in Mission Control. 
Run the gamut of the four B's of music, Bach, Beethoven, Brahms and Brass,

Gemini Control here 67 hours kO minutes and 30 seconds after lift-off. 
The Gemini 9 spacecraft is presently in contact with Canary Island tracking 
station, they're getting ready to take some pictures in fact, they'er discussing 
with the Cap Com at Canary, which island is the tracking station actually on. 
During the Canary pass they put the temperature probe in their mouth to get 
oral temperature measurements of both command pilot and the pilot, and they 
reported also the water usage. Both crew men have had two meals since yesterday, 
the pilot had 5 hours of sleep and the command pilot had 6 hours of sleep. 
After taking these photographs they plan to complete the stowage procedure, 
prior to retro-fire. Just before entering the Canary Island pass, they passed 
over the Eastern Test Range station and reported there that the platform was 
aligned and they had the stowage pretty well under way. Spacecraft Communicator 
Buzz Aldrin, here in Mission Control passed up ball scores to the crew, and 
other less significant type news. Aldrin jokingly asked them if they wanted 
a vector So they could go after the ATDA again. . .cabin pressure aboard the 
spacecraft is holding at k.8 pounds per square inch, and in another exchange 
between Aldrin and Stafford, Stafford said that he might break training and 
smoke a cigar after recovery. We have a tape recording of the Eastern Test

This is Gemini Control, 68 hours, 10 minutes and 30 seconds after liftoff. 
Gemini 9 is just approaching the Carnarvon, Australia, tracking station; 
and hopefully, we'll be able to cut in on the conversation between the 
spacecraft and the station. Meanwhile, here in Mission Control, the 
countdown clock numbers are getting smaller and smaller. It stands now 
at 3 hours, 35 minutes and 51 seconds before retrofire. Early risers in 
the Houston area may get a chance to see Gemini 9 due south about ho degrees 
above the horizon toward the end of the forty- fourth revolution at 6:13 CST. 
The slant range will be about 210 miles. During the final revolution, it'll 
be much nearer Houston, but there will be too much sunlight at that time to 
see the spacecraft. We're still standing by here for Carnarvon acquisition. 
We're still about two minutes away. Still no word out at Carnarvon. We 
should be hearing confirmation of telemetry acquisition momentarily. Shortly 
thereafter, the spacecraft communicator will attempt to raise the spacecraft. 
Carnarvon just reported that the acquisition aid equipment at that station 
had acquired the spacecraft. As yet, the spacecraft communicator has not 
called the spacecraft.

'This is Gemini Control Houston. Apparently a rather quiet pass. 
Tom Stafford, we feel sure, is setting up his retro attitude. 
This is an attitude which means blunt end forward. He will 
be pitched down at 20 degrees at retro fire. Sixty seconds 
before retro fire he will check this attitude very carefully 
and hold it 20 degree pitch down, other rates yaw and roll at 
zero. Simultaneously Gene will press three switches on his side 
of the cockpit one to cut the fuel lines to the adapter, guillotine 
action severing the fuel lines. A second button separates the 
electrical connections, again guillotine that cuts through and 
pinches off the wires and a third button which will separate 
the equipment adapter, the after portion of the Gemini space- 
craft leaving only the retro adapter attached. At 30 seconds 
before retro fire, Stafford will arm his retro squibs, energize 



GEMINI 9A(2) MISSION COMMENTARY, 6/6/66, 1:0k AM TAPE 202 PAGE 3 
the circuits to fire his four retro rockets. At T-10 seconds be- 
fore retro fire, Cernan will arm the automatic retro fire and 
will energize it by starting it. Precisely at retro fire Gene 
Cernan will start a stop watch and the command pilot will push 
the computer, in the start computer position. At retro fire plus 
one second Cernan should press a button which will manually fire 
the retros should any malfunction take place in the automatic 
sequence. He will take a quick check on the computer and he will 
observe the horizon very carefully during retro fire phase. 
Shortly after retro fire, we should hear from the pilots on their 
IVI readout, their incremental velocity indicator, a digital 
clock or dial arrangement in the spacecraft and the values we 
are looking for should sound like this, aft 298, that is a Delta 
V, they are taking out the spacecraft 298 feet per second and 
the down vector should read 112, one one two. We will see how 
close we come to that, the retro fire maneuver itself is to 
take place at an altitude 153-7 nautical miles, one degree 
21 seconds south of the equator at 1.79 degrees 19 minutes west 
longitude. Very close to the Canton Island site. Present 
retro fire time is scheduled for 71 hours h6 minutes and hk

This is Gemini Control Houston. We're 11 minutes and lU seconds 
away from retrof ire . That event programmed for 71 hours , U6 minutes 
and kk seconds into the flight. 19 minutes and 52 seconds after 
retrof ire, we should have reached the U00,000 foot mark over the 
western United States. The blackout period is predicted for 22 
minutes and 8 seconds after retrof ire , or at an elapsed time of 
72 hours and 8 minutes, 51 seconds. The blackout period will end 
at 27 minutes and 5 seconds after retrof ire. Our drogue chute 
should come out at 28 minutes , k7 seconds following the retrof ire 
maneuver. The main chute at 30 minutes, 21 seconds. The landing 
itself at 3^ minutes and 21 seconds after retrof ire. We expect 
fairly good communication today particularly in the landing area 
because we are landing relatively close to Grand Turk Island. The 
landing point is 330 nautical miles almost due East of the Cape. 
During the latter portion of the letdown, once the crew is appro- 
ximately 300,000 feet above the surface of the Earth and coming 
over Texas, they will begin to feel some steering authority, in 
the Gemini spacecraft. The pilots look forward to this period 
of the flight not ,iust because it means the end of a mission, but 
it does present one of the more difficult piloting tasks. We've 
controlled all the landing - Gemini landings - with the one 
exception of Gemini k which came in Mercury fashion or rolling 
reentry. This morning the computer works and the pilots are 
prepared to do a steerable landing. They will be blunt end forward

from roughly 300,000 feet down to about 180,000 - 175,000 feet. 
Their maneuvers will - are planned as a bank left maneuver, 50 
degrees, followed by an immediate bank right, 60 degrees. And 
when they do these maneuvers they will feel some yaw authority

This is Gemini Control Houston, 71 hours, hk minutes into the

communication. It's a little gravelly, somewhat better though than 
the communications were yesterday. We're one minute and 52 seconds 
away from retrof ire . One minute, 23 seconds away. At the one 
minute mark, Tom Stafford will hold the rates very steadily, 20 
degrees pitch down attitude. Other rates will be zero. At the 
same time, Gene Cernan will cut the fuel lines, the electric lines, 
and finally separate the equipment adapter. Mark, 60 seconds to

Those items have separated from Gemini 9- Mark, 30 seconds from

Counting up now at 1^ seconds from retrof ire , we had no report 
from Gemini 9- Four good retros . Gene Cernan sung it out. Four 
good retros. 32 - 33 seconds after retrof ire . 296 - his incre- 
mental velocity indicator shows. The plan was for 298. He was 
within two feet from the planned aft reading. His down indicator 
showed 125. The plan was 112. He's in excellent position. We 
still have no confirmation on retro jettison, the retro adapter 
itself. Now Stafford does confirm that the retro adapter has 
separated. We're two minutes and 13 seconds after retrof ire. 
We're 31 minutes and k2 seconds from splash. Over Hawaii Tom 
Stafford is to give the Hawaii station a detailed estimate on the 
retro maneuver. He will verify again his IVI readouts, and he

Tape 20k, Page 2 

will estimate his attitudes during retrofire. He will a] so advise 
us whether there was an auto - automatic - or a manual retrofire. 
We suspect it was automatic. Three minutes, 26 seconds s'ince 
retrofire and no additional conversation. Hawaii should acquire 
the spacecraft in approximately 20 seconds. Cernan advises that 
the post retro check list has been completed. The post retro check 
list is complete. We're not certain whether that communication came 
via Canton or Hawaii . He should be moving out of the Canton acqui- 
sition area, and we are likely communicating with the spacecraft, 
or will be, via Hawaii. Now the spacecraft is over Hawaii. Here's 
how the conversation is going.

Over the Hawaii station, Dr. Berry's heart scope here is 
showing Stafford with a heart rate of 80 beats per minute. Cernan's 
heart, 100 beats per minute. He had estimated that the rates might 
get up to 130 - 125 to 130 during retrofire. Of course, we have no 
valid - vital information such as heart information via the Canton 
station. That will have to come later from onboard tapes. We'll go

This is Gemini Control Houston. We have some minor revisions on 
some of our events to come here. The blackout period now is estimated 
to begin at 22 minutes and one second after retrofire. We presently 
show l8 minutes and 8 seconds. The next event is the end of blackout, 
27 minutes and 7 seconds after retrofire . The drogue chute should 
deploy at 28 minutes, 1+3 seconds. The main chute at 30 minutes and

Gene Cernan of the times that I just relayed to you. Present 
altitude 60 miles. Spacecraft coming across the White Sands area.

The drouge is out. Stafford confirms that the drouge chute 
has deployed. And on one of the down range aircraft pilots in 
comminication with Gemini 9, the prediction from the spacecraft 
is they will be two and a half miles long. Gene Cernan has just 
advised one of the down range aircraft, two and a half miles long. 
Four minutes and 15 seconds from splash. Thirty minutes since 
retro fire. We are coming up on main chute one. Gene Cernan 
now revises his estimate 3-3 miles long, he indicates. Meanwhile 
Gene Kranz suggests here as soon as the main chute drift takes 
effect, it will revise Ge'ne's estimate. Thirty-one minutes since 
retro fire and since the wind is from the east the betting here 
is that the easterly wind will float the spacecraft right back 
to the aiming point. We will see how this comes out. We have 
had loss of signal from the Cape station since the spacecraft 
is now down very close to the water. We did not get a confirmation 
on main chute. We have a picture. This picture is being portrayed

helicopter out there this morning is being piloted by Lt. Cmdr. 
J. M. Perrengon of North Kingston, Rhode Island. The swimmers

are now deployed. They are in the water and will begin the 
process of attaching the flotation collar which frequently - 
which normally takes about 30 minutes.

GEMINI 9A (2) MISSION COMMENTARY, 6/6/66, 8:Oh a.m. Tape 208, Page 1 

The swimmers have been in phone communication, hard line communica- 
tion, with the astronauts and they have gotten a thumbs up indication at the 
window. The second helicopter in the area , isbteing piloted by Lt. Commander 
Gerald M. Webber, of Jamestown, North Dakota. The carrier advised that the 
collar is inflated and they estimate their present distance -- Wasp to 
spacecraft distance -- at about three miles. 

The communication circuits are really humming from the recovery area. 

Present estimate spacecraft to Wasp is 5700 yards. Swimmers busy out 
there with the collar. Their first assignment, however, is to get a visual 
indication of the conditions and they got that with two big thumbs raised 
in the air. 

The Wasp is moving now at 18 knots toward the spacecraft. The WAsp 
now is presently estimating they will be along the spacecraft at lk minutes 
after the hour, some six to eight minutes from now. 

From the deck of the Wasp, we are told that the astronauts are opening 
the hatch at this time. 

Tom Stafford is standing up in his seat waving to the swimmers. 

This is Gemini Control Houston. Now Gene Cernan also is standing up 

in the spacecraft. The three swimmers working busily around it are Lt. 

JG Ben Bowman, Third Class Daniel Frazier, and Seaman Roger Bates. Tom 

Stafford is shaking hands with one of the swimmers now congratulating them 
good 

on the/job they've done. 

This is Gemini Control Houston, the consensus here this morning is, 
based on past missions, that these communications have been nothing short 



GEMINI 9A,(2) MISSION COMMENTARY , 6/6 /ho, 8 :Ok a.m. Tape 208, Page 2 

of outstanding. We cannot recall a mission where we had more communications, 
it was of good quality all the way in. Tom Stafford was talking to the 
Recovery forces as he came over the east coast of the United States. He 
was in almost constant communication the last 300 miles to the splash 
point about 330 miles off the coast. And, the information flow has been 
excellfflit .

GEMINI 9A (2) MISSION COMMENTARY, 6/6/66, 8:lh A. M. 

Tape 209, Page 1 

This is Gemini Control Houston. Without searching any records, 
we suspect that the spacecraft came down closer to the prime recovery- 
ship than any previous flight - any of the previous 13 United States 
Manned space flights. This the 13th, of course. The landing point, 
somewhere between three and four miles. That will have to be refined. 
We recall that Gordon Cooper on his first Mercury flight landed within 
five miles, approximately four and a half miles, from the carrier out 
in the Pacific also, and he was observed on main chute as he descended 
to the water. Alan Shepherd in his first manned space flight was seen 
and watched as he landed, came down main chute. Several other flights 
have been observed by aircraft and, of course, all of them have been 
followed on radar as they came in, but this appears, immediately, to 
be the closest we've ever come to the prime recovery ship.

This is Gemini Control Houston, during this lull before the pickup. 
Everyone, all the Flight Controllers here in the Control Center are 
watching television like we suspect everyone else is. Someone 
just passed the word on the Flight Director's loop that the Gemini X 
simulations would begin at 3:00 this afternoon. The remark was in 
jest I'm sure but the activities for Gemini X will pickup immediately. 
Probably not before tomorrow morning though.

This is Gemini Control Houston. The spacecraft is presently three 
hundred (300) yards off the port bow of the Wasp. We still don't 
have an estimate as to when the two will be hoisted aboard. 
(PAUSE) 

This is Gemini Control Houston. Our Flight Dynamics bank is 
looking again at their reentry data. Their best estimate right 
now is the spacecraft missed the exact aiming point by some 3,000 
yards. Three thousand (3,000) yards long, which they claim is 
pretty close for Government work. 
(PAUSE) 

This is Gemini Control Houston. Wo 're estimating now that the 
spacecraft will be- hoisted aboard in approximately 12 minutes. 
Twelve to thirteen minutes from now. This is Gemini Control 
Houston.

This is Gemini Control Houston. While we await the pickup, still 
estimated perhaps 5 minutes from now, Gene Kranz the Flight Director 
is going around the loop and congratulating each station, each 
capsule communicator on the job they've done in the last three 
days. The far Western Pacific stations of course were out of contact 
for much of the interesting part. They play a vital role leading 
up to retrofire but they don't always get all of the two-way 
information as we go over the hill east of the United States. 
Gene's congratulating each one of them. We imagine that many of 
them are all even now preparing to make the long flight back to 
Houston. We've also just been handed a copy of a message which has 
been sent out to all the Department of Defense Forces which participated 
in this mission. It reads, "My sincerest congratulations and thanks 
to all of the Department of Defense Forces who participated in Gemini 9 
for their fine contribution to our nations latest space accomplishment. 
We can all take pride in the high degree of professionalism demonstrated 
throughout this mission. I am confident that this same proficiency 
will continue in all of our space missions in the future." It is signed 
Lieutenant General Leighton I. Davis who is the Department of Defense 
Manager for Manned Spaceflight Support Operations. General Davis has 
been with us throughout this mission here in the Control Center in 
Houston. This is Gemini Control Houston.
