This is Gemini Control Houston. Good morning. The 
pilots got up this morning shortly after 4:00 a.m. They 
had a brief physical in the Manned Space Flight Operations 
Building on Merritt Island, and after that, breakfast. They 
left the Manned Space Flight Operations Building at 5:22 a.m. 
and arrived at the suit-up area adjacent to Pad 19 at approx- 
imately 5:35. They were suited and had completed their 
pre-breathing denitrogenation checks by 7:00 a.m. and left 
the pad a few minutes after 7:00. They left for Pad 19 and 
they arrived at Pad 19 at 7:08 a.m. They were in the ele- 
vator within a minute and went over the sill, as we call, 
it, or stepped into the spacecraft at 7:12. In general the 
count has run about 5 minutes ahead of schedule this morning. 
We have excellent weather at the Cape area which will be 
covered in more detail with a report from the Cape shortly. 
Here in Hcuston, the board looks very good. Our status is 
quite good, as a matter of fact ... We are making computer 
runs, we are checking the individual consoles and they all 
look very good and green at this point. This is Gemini 
Control, Houston, at 20 minutes after the hour. 

This is Gemini Cape control. Our countdown is proceeding 
excellently at this time, we are currently at 86 minutes and 
30 seconds and counting. The countdown has gone very welsl

this morning. We have just received a report from the 
blockhouse that we are still some 12 minutes ahead in the 
events of this morning's count. As you probably have seen, 
both hatches have been closed. Astronaut Ed White's hatch 
was closed at 1:31 a.m. EST, one minute later the command 
pilot's also was closed. The astronauts, just prior to 
hatch closure completed a series of blood pressure tests 
with the flight surgeons in the blockhouse. Currently going 
on are several tests at the launch pad, a warm up for final 
guidance checks with the Titan II launch vehicle. Our 
weather this morning also looks good at the current time. 
The forecast of the launch area is 2 to 4/10 's cloud cover 
at 3,000 feet- We have a wind at 5 to 10 knots in the East, 
a temperature of 80 degrees. The mission has been informed 
that the weather conditions throughout the rest of the world 
are in a Go condition for launch. The Ai lantic Ocean will } 
have extensive cloud ceilings of about 1,500 feet. Around 
and south of Bermuda with some scattered showers. The 
mid-Pacific forecast is for scattered, broken clouds with 
a ceiling of 1,000 feet. On the West Pacific storm Carla 
that was Jsyphoon Carla several days ago is reported to still 
be weakening and is not expected to be any problem to the 
mission itself. This is Gemini Cape Control at 84 minutes 
and 47 seconds and counting.

This is Gemini Control, Houston. The count minus - 
I'm sorry- Our clock here, our countdown clock is running 
a trajectory test and is not accurate. At this time we are 
looking here from the Control Center Houston at the, some 
of the vital measurements coming from the spacecraft's 
at Mercury and the respiration rate of Jim McDivit and Ed 
White.- ¥ery nominal values and the reading and the telem- 
etry is quite clean. The count dontinues very much on 
schedule. The earlier count ran as much as 12 minutes 
ahead of schedule. We are also want to bring you up to 
date in the network's status, the around the world status. 
At Tanaverie, we are without voice contact and very likely 
will not be able to have voice contact relayed through 
Tanaverie, and at the Rose Knot Victor Ship, which for this 
mission is parked approximately 1,000 miles off the South 
Americaii Chilian coast is without teletype. Other than 
that, our entire^range of stations around the world is up and 
XM all elements are working very nicely. This is Gemini 
Control at 46 minutes after the hour. 

This is Gemini Control at the Cape. The count is now 
T-63 minutes and counting. T-63. Our countdown continues 
to go excellently at Launch Complex 19. Astronauts Jim 
McDivit and Ed White have just completed purging their cabin 
that is bri]^ing 100 percent oxygen into the cabin which will

cabin. It will remain this way through lift-off. We now 

have the cabin purged and both astronauts are reporting 

back to the pad in a series of switch tests. In this 

particular test, the command pilot and the pilot check 

with the blockhouse to reaffirm that all the switches sxb 

on their panels are set in the proper psKz^XBHX condition. 

At the launch pad we are ready to gear up for one of our 

final guidance tests. All systems are go here at the Cape 

coming up on 62 minutes and counting. This is Gemini

for a test with the Air Force Eastern Test R^nge on some 
missile tracking telemetry. This is Gemini Control at the 
Cape coming up on T-53 minutes and counting. Mark, T-53 
minutes and counting. 

This is Gemini Control in Houston. The count is T-45 
minutes and proceeding and we're right on the money. Moving 
right ahead with all the pre-launch verifications in the 
spacecraft. About a half an hour ago, shortly after he 
entered the spacecraft, Jim McDivitt put in a phone call 
to his wife in Houston, They chatted for about 5 minutes. 
We are unable to confirm at this time whether Ed White has 
talked to his home or not. Ed's been fairly busy with a 
series of communications checks. Meanwhile the viewing 
room here at Houston and I am sure at the Cape also, is 
filling up. Congressman Bob Casey from Houston is here. 
Dr. Robert Seamans, the Associate Administrator of NASA 
is in a chair in the viewing area here, along with some of 
our better known astronauts. Former astronaut John Glenn 
has been in the Control Center for the past hour. Wally 
Schirra is down on the floor of the control center at this 
time chatting with Gus Grissom who will be the capsule 
communicator during the launch phase from this center. 
Our general status continues to be excellent. This is 
Gemini Control.

This is Gemini Control at the Cape. Our countdown 
continues to run smoothly here at Complex 19. All conditions 
look good. Our count is still a little bit ahead, launch 
vehicle test conductor has given permission to the pool to 
lower the erector a little earlier than planned. We do not 
have a specific time at this time. The erector is due to 
be lowered at T-35. This is Gemini Control at the Cape. 
T-38 minutes and 20 seconds and counting. 

This is Gemini Control at the Cape. We are now at 
T-35 minutes and 20 seconds and counting. We are coming 
up on T-35 and some 5 seconds. T-34 minutes and 59 seconds 
and holding. This is Gemini Control at the Cape. Holding 
at T-34 minutes and 59 seconds holding. We will get infor- 
mation to you on the hold momentarily. 

This is Gemini Control at the Cape. We are now at 
T-34 minutes and 59 seconds and holding. I have a report 
from the blockhouse and difficulty is concerned with the 
erector around the Gemini 4 launch vehicle. The explanation 
at the present time is we have an electrical failure in the 
erector system. We are not able to lower the erector at the 
present time. The extent of the hold is not known at this 
time. T-34 minues and 59 seconds and holding. This is 
Gemini Control at the Cape.

Control 

This is Gemini jK at the Cape. Our hold on the mission 
still remains at T-34 minutes and 59 seconds. The difficulty 
as reported earlier is with the erector on the launch pad. 
The launch vehicle test conductor has just reported that he 
estimates the hold time at about 30 minutes. The plan is to 
get some of the crew up on the launch pad to take a look to 
see how we stand. As far as trying to determine the difficulty 
from the blockhouse, the launch vehicle test conductor further 
reports that there are no red line problems in the blockhouse, 
that is, all the gages in the blockhouse give no indication 
of the difficulty. We expect to have more information shortly. 
We are holding at T-34 miniles and 59 seconds. This is 
Gemini Control at the Cape. 

This is Gemini Control at the Cape. Our hold remains 
at T-34 minutes and 59 seconds and holding. From the 
blockhouse astronaut Schweikart reported to the astronauts 
in the Gemini 4 spacecraft that the hold was estimated to 
be about 30 minutes. Astronaut Ed White replied back to 
Schweikart "We are all squared away." We are still looking 
to determine our exact problem and awaiting word from 
the launch vehicle test conductor on the status of our 
erector problem. We are holding at T-34 minutes and 59 
seconds. This is Gemini Control at the Cape.

This is Gemini Control at the Cape. As you can see 
now looking at Launch Complex Pad. 19 our erector is starting 
to move. Still holding at T-34 minutes and 59 seconds. 
It is expected that the count may be resumed in a matter 
of some 12 to 15 minutes. We expect to have further infor- 
mation on the resumption of the count dhortly. This is 
Gemini Control at the Cape. 

This is Gemini Control at the Cape. The launch vehicle 
test conductor has reported back to mission control that our 
difficulty in the erector was concerned apparently with a 
faulty relay in a relay box at the base of the gantry 
erector on launch complex 19. This relay has been replaced. 
The erector has started to move. The plan is to once again 
raise the erector to k its full position, however, before 
continuing with the count. We are going to make one more 
check of the erector prior to resuming the count. This 
is Gemini Control at the Cape at T-34 minutes and 59 seconds 
and holding. 

This is Gemini Control at the Cape. To further clarify 

our problem with the faulty relay at the base of the erector. 

The relay was not replaced. The relay did not close and an 

we 

attempt to check it out, /physically, that is manually, 

depressed the relay to make it close. We are now checking 
on certain locks on the erector to determine that we will 
be able to lower the erector. It's several feet away

from the spacecraft now. Still taking several more tests. 

When we are ready to lower we then will Ica/e to clear the 
from 

crew XH the launch pad and resume the count. We are still 
at T-34 minutes and 59 seconds and holding. Here in the 
Mission Control Center at the Cape at the capsule communi- 
cator's console we have chief astronaut Alan Shepard and 
the backup pilots for the Cemini 4 flight. The prime 
backup pilot, Frank Borman was at the launch pad during 
the early checkouts. Frank then went to the trailer when 
the prime crew came to dress at launch complex 16. Frank 
briefed astronauts Jim McDivitt and Ed White on the status 
of the mission at that time. In the meantime, the backup 
pilot, Jim Lovell remained in the spacecraft making final 
checks up to the time the prime pilots McDivitt and v^hite 
came to the launch pad and were inserted in the spacecraft. 
Both Borman and Lovell are with astronaut Alan Shepard at 
the capsule communicator console in Mission Control at the 
Cape. From the viewing room ere astronauts Pete Conrad, who is 
the pilot for the GT-5 mission and astronaut Neil Armstrong 
who was the prime backup pilot for the Gemini 5 mission. 
Also in the viewing center is Dr. George Mueller who is 
NASA's Associate Administrator for Manned Space Flight, we 
are still holding at T-34 minutes and 59 seconds. This is 
Gemini Control at the Cape.

This is Gemini Control at the Cape. We are still 
at T-34 minutes and 59 seconds and holding. We now have 
the report from the launch pad that we are still encountering 
difficulties with the erector on the launch pad. We felt 
that we had solved our electronics problem by closing, 
3czKxk±x physically closing the relay we discussed earlier, 
that is a relay in a relay box at the base of the erector, 
however, it is now reported by the crew out at the pad 
they have further difficulties with the erector. The 
difficulty concerns a cable that rides down with the erector 
as it is hydraulically lowered. This cable in turn is used 
to raise the erector at different times. The cable has 
slack in it, is the report. The cable is controlled by 
a winch based at the launch pad. Because of this slack 
an automatic override comes in and cuts <fan the erector 
lowering process. As a result we are now checking in the 
cable rope itself in an attempt to solve this problem of 
the slack in the line. The test conductor on the pad 
reports that he does have ±kB an aix estimate on the 
extent of the hold. As soon as we get further information 
we will pass it on to you. We are still holding at T-34 

minutes and 59 seconds. This is Gemini Control at the 

Cape .

This is Gemini Control at the Cape. We are still holding at 
T-5^ minutes 59 seconds at' Launch Complex 19- The crew . . , the 
pad area doing further investigation on our cable problem that was 
discussed earlier. They are still looking over the situation, we 
do not have an estimate on the hold at this time. This is Gemini 
Launch Control at the Cape. 

This is Gemini Control at the Cape. We are still at T-J^ 
minutes and 59 seconds and holding. We are continuing our tests 
with the erector on the launch complex. You may note that the 
erector has moved slightly from its umbilical tower as the test 
continue. We are moving a matter of a few feet from the tower, 
but the plan is not to move the erector at this time. The erector 
is moving slightly as part of the test that is currently in progress 
to determine the full extent of our difficulty. The Launch Vehicle 
Test Conductor has been able to give no further information on the 
length of the hold at this time. We are at T-5^ minutes 59 seconds 
and holding. This is Gemini Launch Control at the Cape. 

1h±s is Gemini Control at the Cape. As you can see at Launch 
Complex 19, we are now starting to lower the erector as we continue 
our tests. We will know shortly whether we will be able to fully 
lower the erector at this time. This is still a test continuing. 
We will pass on the information to you shortly. We are still holding 
at T-34 minutes and 59 seconds. This is Gemini Control at the Cape. 

This is Gemini Control Houston. We are still holding at T-55 
minutes, but we expect to pick up the count momentarily. The erector 
has been lowered and we expect within a minute or two to resume the

count, A final status check is being taken at this time in the blockhouse 
to — preparatory to picking up the count. Meanwhile^ during this hold 
which began an hour and 10 minutes ago, the crew has passed the time, 
released a part of the time taking catnaps. Astronaut Rusty Schweiker, 
who is in the Mission Control Center at the Cape advised them when the 
hold started that he would wake them up when we had planned to resume. 
The reference was of course a hopefully to break a little of attention 
in this countdown. The problem appears to have been in an electrical 
governor on the erector lowering device. It has been repaired and we 
are satisfied the erector is properly down and in its place. We have 
been asked many times in the last half hour what effect this ho\ir and 
10 minute hold might have on our planned extravehicular activity in 
the second revolution of this mission, and Mission Director Criss Craft 
advises that it will have no effect. We will still plan to begin the 
extravehicular activity at 5 hours into the mission at the — near the 
end of the second revolution. This is Houston Gemini Control still 
holding' at T-55 minutes. 

And counting — l-'^k minutes and mark — 50 seconds. T-3^ minutes 
50 seconds and counting on the Gemini Flight. On this point in the 
countdown in the blockhouse we are ready to turn over the remainder 
of the countdown to the automatic sequencer in the blockhouse. Hie 
sequencer itself will check some 70 different items during the terminal 
phase of the count prior to ignition and lift-off. We are now coxinting 

on the Gemini k. This is Gemini Launch Control at the Cape. 



Mission Commentary Transcript Tape 3, Page 

This is Gemini Control in Houston, We are proceeding the count 
at T-50 minutes and moving ahead. And, "barring further difficulties, 
we should be off at 15 minutes after the hour. A little more than 30 
minutes — just under 30 minutes from now. Our status on the ne-twork 
which we have not report on now for more than an hour looks as follows: 
it is absolutely green. Earlier we reported Tanaverie had some voice 
relay problems , those have been cleared up. Hie RKV seems to have 
cleared up its teletype circuit problem, and the board at this time, 
all of our stations around the world are reporting no difficulties 
at all, and this is very much the situation with the spacecraft and 
the launch vehicle at the Cape. Say for one small electrical problem 
in the lowering device at Pad I9. This is Gemini Control Houston. 

Biis is Gemini Control at the Cape coming up on T-25 minutes 
and counting in 5 seconds. MARK. T-25 minutes and counting on the 
Gemini k flight. At this stage in the count. Astronaut Ed White is 
ready to start a series of verifications as far as voltage readings 
are concerned in his cabin, in the pilot's cabin itself. This series 
of readings will be current readings and voltage readings will be 
passed onto the block house and to the Control Centers involved. Biis 
is to insure that all readings are correct before proceeding with the 
count. Our count is once again running smoothly now at 1-2k- minutes 
and 50 seconds away from lift-off prior to the Gemini h flight. This 
is Gemini Launch Control at the Cape. 

This is Gemini Control Houston. The count T-20 minutes and 
counting. We have, within the last 5 minutes, completed an OAMS 
thruster check on the adapter on the spacecraft and it had worked out 
very nicely. All the thrusters, the two up, the two down, the two yaw 
thrusters, the two forward thrusters would not check, but the others

worked out entirely satisfactorily. We, within the last minute, have 
completed a complete systems check in the blockhouse. That was go 
in all of some I3 or 1^+ elements which were all that were polled. 
The mission looks very good, now proceeding at T-19 minutes at this 
time. This is Gemini Control Houston. 

On the Gemini k mission. All systems are good at this time. 
Even at this stage of the countdown some of the checks had been performed 
earlier, then planned in the countdown because the count is once 
again proceeding so well. All conditions are go at the present time. 
Fifteen minutes and 30 seconds prior to lift-off. Ihis is Gemini 
Launch Control at the Cape. 

The Pilot . is now conducting a test with the Eastern Test Range on 
telemetry between the range tracking systems and the guidance and 
other equipment from the vehicle itself and sending back signals on 
the progress of the launch. We are still In a go condition at 9 and 
one-half minutes and counting. 

This is Gemini Launch Control at the Cape. 

Go ahead flight 

This is Gemini Control Houston with the count T-5 minutes and 
counting. At T-7 minutes we completed a spacecraft Test Conductors 
Status check and all elements were green and go. At the conclusion 
of that status check spacecraft test conductor Frank Wittek of the 
Kennedy Space Center signed off to Jim McDivit with a short message 
which simply said "OK Jim, have a good flight". In the last minute 

the launch launch vehicle test conductor Frank Garret of Martin 
Company is conducting his status check. The board looks Just as 
Green as the spacecraft. The count T-h minutes and 50 seconds and 
proceeding. This is Gemini Control Houston.

(Houston) Liftoff. We have a liftoff at 16 minutes 
after the hour. Climbing very nicely. We have a roll 
program initiated. Roll program completed McDivitt reported, 
and the pitch program has been initiated. 

Forty seconds is in and surgeon says everything looks 
fine. Mark 50 seconds and we're go. 

Guidance reports a Go. The flight trajectory looks 
very, very close to right on the nonimal value. 

We just had a short transmission from Gemini 4 where 
both of them are beautiful . .beautiful . 

Gus Grissom advises the Gemini 4 spacecraft at one 
minute forty seconds, this means a change in the abort 
mode if necessary, doesn't look like its necessary from 
this point. We're having some transmission difficulty from 
the spacecraft, the transmissions are intermittent. 

Two minutes and 7 seconds into the flight and everything 
looks fine here. 



Mission Conunentary Transcript ^^P^ ^^^^ 

McDivitt reports Gemini 4 is Go for staging which will 
occur is a few seconds. Pilot White advises he's received 
an update on the computer for that spacecraft. We have 
staging and its been confirmed here on the ground , The 
thrust looks good on the second stage. Our radio guidance 
system which controls the terminal phase of powered flight 
has gone into effect and is working very nicely. Three 
minutes into the mass ion, three minutes. 

And the trajectory plot is right on the line both in 
lofting and all other elements we're right on the money. 

Gus Grissom advises Jim McDivitt everything looks 
great, Jim, and Jim says his displays in the spacecraft 
look just as good t as those in the control center. 

Three minutes and fort|i seconds. 

Mission Director Chris Kraft going from console to 

console here and from each one he gets a completely confident 

and assured report that everything looks good. We're four 

minutes into the mission and McDivitt, in a very, very calm 

voice says it looks great up here. Kraft is advised to 

status 

stand by for a final/check before we go to the final 
minute Bir before engine cufeoff. Kraft has told Grissom 



Mission Commentary Transcript tape 4i Pa/^^e ;5 

to give Jim McDivitt a Go, its been received and McDivitt 
advises he also is Go. 

Four minutes and 50 seconds and our values are right 
on the money. 

We're standing by for point 8, that point where we 
have acquired 80 percent of the velocity, 80 percent. 
Five minutes and 17 seconds in. Guidance says we're 
solid, both systems, the primary system in the booster and 
the video guidance system. Five minutes and 30 seconds. 
Stand by for sustainer engine cutoff. SECO McDivitt says, 
and Grissom confirms here on the ground we have a SECO. 

Flight plan calls for McDivitt to uh..,, we've been 
given a Go by Kris Craft, Chris repeats Go Gemini 4. 

We are standing? by to get a signal from McDivitt to 
find out when he separates from that second stage. 

Six minutes and 50 seconds in. Gemini 4 has been 
asked to switch to another channel to clear up some. , , . 
here we come..,, Jim McDivitt advises he has an incremental 
velocity indicator within the spacecraft during the separation 
maneuver which has occurred within the last minute read 
as follows: 20 forward, 7 right and 2 down.

...And McDivitt advises he's turning around at this 
time to face the booster. He says the second stage which 
he now has in view looks pretty, he says its also tumbling 
slightly. 

This is Gemini Control in Houston, eight minutes and 
30 seconds in on the mission, Grissom here, the capsule 
communications operator has just passed to Jim McDivitt 
and Ed White via our Bermuda station the following orbital 
elements: 100 statute miles at perigee, 175 statute miles 
at apogee- Uh.. this is exactly what the book calls for. 
We're 9 minutes in.... and, uh, stand by and we'll be pre- 
pared in a very few minutes to play the booster phase 
tape conversation for you,... stand by. 

This is Gemini Control, Houston. The spacecraft at 
this time is directly over our Canary Island station it 
is beginning its passage across the African continent, we 
are, uh, in excellent voice contact now. The crew has 
switched to a second, or backup unit UHF channel which 
reads much clearer than did the other UHF channel we 

were using in the launch phase. 




Mission Commentary Transcript '^'a^pe 4, Pat'e v 

Communications are coming through. They are excellent. 
Upon contact in the Canary Station. Jim McDivitt was advised 
that his status looks excellent from the ground and McDivitt 
came back with a Roger, thank you. They've read out their 
onboard quantities which appear, uh, which appear to be quite 
nominal in the spacecraft at this point. They are being 
updated as to the time and exact references for a recovery 
should one become necessary at the end of the first revoltuion. 
We've received nothing in this first 20 minutes of flight 
which would make such a recovery necessary but it is standard 
procedure to pass this along. We can hear Ed White's big 
baritone voice booming in now, into the Canary Station 
being relayed back here. This is Gemini Control at 20 minutes 
after the hour. 

the spacecraft seems to be very nicely 

and the two crewman working hard at this time to line up 
their platform in preparation for this early rendezvous 
maneuver. The, uh, the, we monitored the conversation 
very carefully over the Canad.es and they were asked what 
their distance from the booster was$ we thought we heard 
Ed White say its about 500 feet away, but, uh, I cannot 
confHX irm he actually said that.... I thought I heard him 
say 500 feet. If, uh, in fact he did say 500 that would 



Mission Coiranenatry Transcript Tape 4, Page 6 

rhymne very nicely with the approximate* distance that, uh, 
wherein the two vehicles should be located. Uh. . .we, uh, 
should update you on the types of cameras being carried 
aboard. We have not one, but two, 16 millimeter movie 
cameras. One will be mounted about a foot aft of the cabin 
that is on the adapter during the extra vehicular maneuver; 
White will mount this after he opens the door and it will 
take 16-millimeter color movies at a rate of six frames 
per second. Uh, in the other window McDivitt will operate 
a 16-millimeter camera, uh, each camera has approximately 
100 feet film or some 15 minutes. The addition of the 
camera on the adapter was a fairly last minute thing finally 
arrived at during the last two days at the Cape, Uh... 
White also will operate a counterex camera on his little 
maneuvering unit as he is out in space. In addition to that 

will be available in the spacecraft a 70millimeter Hassel 

camera. At this time the spacecraft is traveling on the 
edge of the Kano acquisition circle 28 minutes into the 
mission. .. .we have the tape for you on the Canary Island 
pass, we'll play this tape for you at this time. This is

This is Gemini Control Houston. We are 59 minutes into the 
mission. The spacecraft is just east of the Tanaverive Malagassy 
station over the Indian Ocean. We have not been in touch with the 
spacecraft since the Canaries. Gus Grissom our communicator here 
attempted a voice relay transmission through Tanaverive, but if 
it was successful in reaching the spacecraft^ we do not know. They 
did not respond. During this period, as the spacecraft moved across 
Africa, the flight plan called for Ed White to perform an all important 
suit integrity check on his suit. We should next have contact with 
the spacecraft over the Carnarvon station in 5 to 5 minutes from 
now. This is Gemini Control Houston. 

Fifty seconds to go. The Carnarvon Station just established 
contact with the Gemini k spacecraft and the opening commentary was 
the question from Carnarvon, how does everything look. Jim McDivit 
came back very promptly, we're go. Everything here looks green. 
He has - he is now discussing his — some of the maneuvers he performed 
to get the booster in sight and he has confirmed our estimate at the 
Canaries at which point we was k to 500 feet from the second stage. 
All of his systems onboard give entirely nominal values at this time, 
he said everything couldn't look better and we are having a very 
active discussion over the Carnarvon station. This is Gemini Control 
at 8 minutes after the hour. 

This is Gemini Control Houston. We are 20 minutes after the 
hour and during the recent pass over Carnarvon, some 2 minutes ago, 
Gemini k was given a go for three orbits. Three orbits. Perhaps

even more important, the Dr. Berry, our flight surgeon, has made an 
evaluation of the data of the medical data to this point, and he 
has advised mission director Cris Craft, that the Pilot, Ed White, 
as far as the surgeon is concerned, is go for the extravehicular 
activity. He is quite satisfied with the values he has seen in this 
first half of the orbit. Our apogee, again, 175 statute miles, our 
perigee, 100 miles. We are estimating the time of a revolution at 
9^ minutes, that is the time back to the Cape during the pass Command 
Pilot Jim McDivit reported that the lights on the booster were 
working very nicely. He said they could observe the booster about 
a half mile away which is precisely the distance it should be. 
Mission Director Craft complimented the Carnarvon station at the end 
of the pass on the quality of the material received. Very shortly, 
McDivit and White should be seeing the first ks^sx of, hopefully, 
about 62 sunrises that they should observe in the next h days. 
Starting across the Pacific at this time, we have the Carnarvon tape 
ready and will play it for you right now.

C Roger, the light is working fine. But I can't tell exactly how 
far away I am from it. I guess I am probably around a half a 
mile or so. Ihe booster started 'turning right as we came off

looked like 20 degrees per second but as soon as we got off and 
I got around to see it it was tumbling.

Mission Coimnentary Transcript ' 

This is Gemini Control Houston, 1 hour and 25 minutes 
into the flight of Cemini 4 and the spacecraft rapidly- 
approaching the west coast of Mexico- As the spacecraft 
moved across the Pacific we attempted a voice relay through 
the Canton Station, it was unsuccessful. We did not contact 
them however the Canton Station was reading some telemetry 
values as it passed over. To repeat, our apogee is 175 
statute miles, our perigee 100 statute miles, our revolution 
period an estimated 94 minutes. We've had report from 
Jim McDivitt of the Canarvon that the lights were working 
very well on the booster - he could see the booster - it 
was about a half a mile from him, uh... in that pass Dr. 
Berry advised that based on the medical data up to Canarvon 
Ed White was Go for the EVA maneuver in the next revolution. 
The mission director also passed to the crew a Go for at 
least three or.., three revolutions. The tumble rate of 
the booster which is some 28 feet long, 10 feet in diameter, 
and has a ground, if it were on the ground it would weigh 
about 6,000 pounds, otherwords , roughly the size of a house 
trailer, uh. . it's somewhere between 20 and 40 degrees, 

that is a pretty sharp tumbling rate and could 

have an impact on our rendezvous, that is we, advise before 



Mission Conmientary Transcript Tape 6, Page 2 

the mission the tumbling rate was fairly high we'd not come 
too close to the booster. Interestingly, during the lift-off 
phase, we had an EKG monitor not only on Pilot Ed White and 
Command Pilot Jim McDivitt, but we're also calibrating the EKG, 
the heart rate of Chris Kraft, the Mission Director, and the 
Flight Surgeon, Dr. Berry. The values were these: at lift-off 
Jim McDivitt 's heart rate was 150 - which was about the expected 
value - Pilot Ed White was 120; the Mission Director, Chris 
Kraft's heart rate was 135, and Dr. Berry's - the Flight Surgeon, 
was an unusually low 81. This is Gemini Control as we have now 
just established contact with Gemini 4 from our Guaymas station. 
Gemini Control, Houston. 

This is Gemini Control, Houston, one hour and 32 minutes 
into the mission. The spacecraft is slightly east of the White 
Sands station at this time. We've had communication between 
Guaymas and White Sands. Pilot Jim McDivitt is advised at this 
time he has used approximately 100 feet per second - or in other 
words, about 50 percent of his OAMS capability in attempting to 
maneuver close to the booster. He's been cautioned to attempt 
no further maneuvers at this point. He has just received a 
Go - a confirming Go - for the extra -vehicular activity. His 




Mission Coiranentary Transcript ^^P*^ ^» 

distance from the booster remaining somewhere between a half 
mile at apogee and something like three or four hundred feet 
at perigee. The cabin pressure has been reported as holding 
between 5 and 5.5 pounds per square inch. McDivitt is asking 
for a precise reading on the orbit of the second stage, which 
would become very critical in the event that we do attempt to 
close on it further. However, additional closing is not indi- 
cated at this time because of the high usage rate thus far in 
the flight, and his attempts so far to close on it. This is 
Gemini Control, one hour and 34 minutes into the mission. 

We're going to start the Guaymas tape in 15 seconds. 

This is Gemini Control, Houston. We'd like to play for 
you the - at this time - the tape of the conversation as the 
spacecraft moved across the United States. 
CC Guaymas PCN solid. 
S/C Roger . 

S/C Guaymas, Gemini 4. 

CC Gemini 4, Guaymas Cap Com. 

S/C Roger, Guaymas, we still have the booster. We're out quit 
a ways from it now. It's taken a little more fuel than 
we had anticipated. We've got 61 in the fore and aft 
window and the after 37 left and 36 up at the present time 



Tape 6, Page 4 

Mission Commentary Transcript 

We appear right now to be just about holding our own with it. 
Of course, we should - as we progress here - we should start 
to close with it but it's out further than we had hoped to 
let it get right now. 
CC Roger, I copy. 

S/C Is there any way of giving me a quick check on what my 

orbit is. This thing is way below me. 
CC Wilco. 
S/C Say again. 

S/C I say the booster is way below me. Could you tell me what 

my present orbit is as soon as possible. 
CC Roger, We're working on it. 
CC We'll do that. 

Kraft: Tell him it'll probably be this pass over the States 
before we can get it to him. 
CC Say again, flight. 

Kraft: Probably be after the pass over the States before we 
can get it to him. 

CC Gemini 4, we'll update you with the orbit calculations 
sometime after the pass over the States. 

S/e Roger, understand. And bsides our cabin pressure seems

to be holding even here below 5. It stabilized out initially 
at 5.5 and decreased to 5.25 and then went back up to 5-1/2 
and it's now down a little below 5. 
CC Roger, we copy. 

S/C Would you want to get a confirmation for me on that on the 
ground . 

CC Roger, we're working on it. Put your quantity ... rate 
S/C Roger, going to read. 

S/C Guaymas, this is Gemini 4. We're going to have to get 
resolution right away. Do you want me to really make a major 
effort to Close with this thing or to save the fuel? 
Kraft: I think we should save the fuel. 
S/C Guaymas, do you read Gemini 4? 

CC Roger. We copy. We suggest that you stand by. We want to 
save the fuel. 

S/C Roger. I guess we've already expended about a hundred 
feet per second. 

CC You've expended a hundred feet per second? Roger. 

Kraft: I don't think it's worth it. 

CC We're finished with the quantity readings. 

CC Gemini 4 . 

S/C Roger.

CC You can place the quantity read switch to off. 
S/C Rog . 

CC Flight, Guaymas. 
Kraft: Go ahead. 

CC Ok. On the ground, the cabin's holding fairly steady at 

5.2. Did you copy the readouts of the spacecraft? 

Kraft: Affirmative. You might tell him that as far as we're 

concerned we want to save the fuel. We're concerned about the 

lifetime more than we are matching that booster. 

CC ' Gemini 4, Guaymas Cap Com. Flight advises that he'd like 

to save the fuel. You'll be advised over the Cape. 

S/C I just can't wait till I get to the Cape. I guess we're 

just going to hove to watch it go away. I'd like to save 

enough to help bring me down - I don't want to get down to 

wherever it's going. 

CC Roger. 

Kraft: Tell him to forget it. 
CC Ok. I guess we'll scrub it. 

S/C Ok. Get me a tag on my orbit as quick as you can. 
CC We're working on it. Did you get that, Flight? 
Kraft: Affirmative - I got that.

This is Gemini Control Houston. The spacecraft at this time 
is over the Canary Station. We are 1 hour and 51 minutes into the 
mission. Since the pass across the United States, the Mission 
Director and his Systems Advisors have consulted and based on the 
usage of fuel up to this point which is - the usage has been an 
estimated l60 feet /sec available out of a total of 36O feet/sec 
available leaving him 200 feet per second, the Mission Director 
has decided not to attempt any closer approaches to the booster 
that is, he will not attempt the Gemini h spacecraft will not 
attempt to come closer to the booster during the - during this 
revolution when we will attempt extravehicular activity, and he 
will not attempt to come any closer during the fifth revolution as 
previously announced.

The new elements for the spacecraft has resulted in maneuvering 
during the first revolution or IO3 mile perigee that's statute miles, 
and 180 miles apogee. White has been busy the last 5 minutes 
unstowlng his extravehicular equipment and adjusting it, getting ready 
for his - the hatch opening. This is Gemini Control at one hour and 
52 minutes into the flight. This is Gemini Control Houston. Two 
hours and 11 minutes into the mission with the spacecraft over the 
Tanaverle station.

As the spacecraft moved across the African continent, Ed White 
was busy going through the detailed checklist, some hO items long, 
and preparing for his extravehicular maneuver, getting his gear out 
of various storage boxes, putting it in place, moving the switches 
to the right position and presumably, he has accomplished most of 
that preliminary work at this time . We see no constraints at all on 
the extravehicular activity at this particular moment . They look 
very good in the spacecraft . The Pilot and the Command Pilot have 
been advised that they can play their attitudes anyway they like, 
that is they can be hatch up, or hatch down during the extravehicular 
activity, and, in

This is Gemini Control, Houston. Two hours and 25 minutes 
into this mission. And v;ithin the last 30 seconds we've 
established contact with the Gemini 4 spacecraft at Carnarvan. 
Pilot Jim McDivitt - Command Pilot Jim McDivitt at this time 
is giving the ground the blood pressure reading. He advises 
that Ed White is in the final stages of hooking up his umbilical 
and his other equipments necessary for the extra- vehicular 
equipment - for the extra-vehicular exercise - pardon me. He 
also advises that things are running a little slow on the 
checklist but apparently it's nothing too serious. Within 
six minutes, the general plan calls for Ed White to switch 
over to his extra-vehicular equipment and go off the spacecraft 
cabin environmental control system, at which point he'll make 
a final check of all his emergency equipment for that extra- 
vehicular maneuver. Let's tune in now to the tape as it's 
started - the conversation at Carnarvan. 

S/C . . .right now. He's trying to get his umbilical on. 

CC Ok. We need a blood pressure reading from the Command Pilot. 

S/C Stand by one. You might advise Flight, by way of the 

land lines that we're running late on this thing. There's a 

lot to do and we're having trouble keeping track of all this. 

CC Ok. Copy that. Flight?

CC Roger. Flight, Carnarvan. 

Flight: Go ahead. 

CC He's running late on his flight plan. 
Flight We understand. 

CC Ok. I'm going to cut off on the count checks. 

S/C You want it back on continuous?

S/C Roger. I can't give you a good blood pressure. The bulb 

popped off. 

CC Flight, Carnarvan. 
Flight Go ahead 

CC He's having trouble with the blood pressure bulb. It just 
popped off. You want to give him the EVA go? 
Flight Affirmative

CC Roger, we'll go without the blood pressure then. 
Flight Affirmative. 

CC Gemini 4, you are go for the EVA and decompression. Dis- 
regard the blood pressure unless you've got ten minutes. Then 
try and get a pressure. We'd appreciate it. 

S/C We don't have any time at all. We're really pressed here. 
CC Ok. 

CC Ok, between your first and your second repressurization 
in that wait period, we want you to put your radiator in bypass 
and in the flow after you repressurize the second time. 
S/C Roger . 

S/C Just advised Cap Com that we're running a little late and 
we might not be ready at Hawaii. 
CC All right - he knows that. 

Flight You might tell him if he doesn't make it this pass, 
we'll take his evaluation and we'll do it next pass. If he 
doesn't think he can make it. 

CC All right. Houston advises that if you are unable to 
make it this time, we'll take your evaluation and we'll pick it 
up on the next pass. 
S/C Roger, understand that.

Mission Commentary Transcript 

CC Ok. You don't have to acknowledge this. You're in 
an 89.2 by 155 orbit. And it's a 4.8 day lifetime. 

This is Gemini Control, Houston. Two hours and 35 
minutes into the mission. And Ed White and Jim McDivitt are 
making their final preparations for an extra -vehicular activity 
at this point the spacecraft is on the northeast coast of 
Australia. Meanwhile, within the last minute, we've been 
advised by our Department of Defense recovery room here at 
Houston that an airplane - a C-54 telemetry airplane is having 
some engine trouble. Its position right now is 350 miles south 
of Bermuda. It's returning to Bermuda with one engine out. 
The situation is not considered critical, however, other air- 
planes will go out and meet the C-54 and bring it in to Bermuda . 
The aircraft with engine trouble is estimating Bermuda in about 
one hour and fifty minutes from now - ten minutes before noon 
CST. This is Gemini Control. 

This is Gemini Control, Houston. Within the past minute 
the Canton station has raised the Gemini 4 spacecraft and the 
Command Pilot, Jim McDivitt, advises that all is in readiness 
for the extra vehicular maneuver. Here in the Control Center, 
the Mission Director wanted to pass along the information that

if they were at all rushed on the flight plan just to hold off 
for one pass and do it the next pass. But the word from Gemini 
4 is that all the connections have been made and they're quite 
ready and prepared to undertake the extra -vehicular maneuver. 
They're standing by momentarily for some word from Hawaii at 
which point - or within a few minutes of LOS at Hawaii - we're 
not just sure, the right hatch door should be opened. This is 
Gemini Control, two hours and 49 minutes into the mission. 

This is Gemini Control, Houston. The Hawaii station has 
just been in touch with Command Pilot Jim McDivitt . He 
apparently has decided that things were a bit too rushed and 
has elected to wait until the next pass around in order to 
attempt his extra -vehicular activity. The first indication 
we had of this was the cabin pressure reading on the ground 
which still showed something over 5 pounds of cabin pressure. 
Within seconds after that, Jim McDivitt ' s voice came up on 
the loop and he said that they had decided to wait until the 
next revolution. Apparently all of the connections and the 
unstowing of articles got a little hectic there over Carnarvan. 
We did note that Ed White was working awfully hard to get his - 
all of his connections strapped on. The feeling here was that, 
if they so elected, they could certainly wait until another 



ILL 



Tape 8, Page 6 

Mission Coitimentary Transcript 

revolution and they have taken that choice. This is Gemini 
Control. The spacecraft at this time is some 700 to 800 
miles southeast of Hawaii, proceeding toward the United States. 
We should have contact from our California station within three 
to four minutes and we expect no further advisories until that 
point. I want to reaffirm that the status aboard appears to be 
excellent at this time. The pilots have elected to wait one 
more pass before attempting the extra-vehicular activity. Two 
hours and 53 minutes into the mission. This is Gemini Control, 
Houston . 

This is Gemini Control, Houston. We have re-racked the 
tape from the Hawaii pass and are prepared to play it for you. 
I think you'll note the unusual clarity of the conversation. 
As best I can recall it's about the cleanest one we've had so 
far into the flight. Could we have that tape now, please.

S/e Roger, Hawaii. I read you loud and clear. 
CC Roger. What is your status. 
S/C Standby one. 

CC Houston Flight, the cabin pressure is 5.4 on my meter here 

on the ground. 

S/C Hawaii, Gemini 4. 

CC Go ahead, Gemini 4.

S/C Next pass around. I don't think we want to try it. 

CC Understand next pass around. 

Flight: Tell him we're happy with that. 

CC Roger, Gemini 4. We're happy with that. 

Flight: Hawaii, Houston Flight. 

CC Go ahead. Flight. 

Flight: Tell him to get back on the normal suit circuit. 

CC Roger. Gemini 4. Hawaii Cap Com. 

S/C Stand by one. 

S/C Ok. Go ahead, Hawaii. 

CC Roger. Flight advises go back on normal suit circuit unt 
next round and then go back over Carnavan.

This is Gemini Control Houston. Three hours into the mission 
and within the past minute, 30 seconds actually, our California 
Station has raised the spacecraft, Gus Grissom is in conversation 
with Jim McDivit at this time and let's tune in live on that 
conversation as it moves across the United States.

CC Say again. 

S/C Just wanted to confirm if we had passed the retrofire time, 

CC Hey Jim, you do have your computer on, don't you? 

S/C Negative, I don't have it on. Do you want it on at this 
time. 

CC Ah, roger, cut it on. We are going to give you a h-k time, 

S/C Okay, I thought we were going to get it later. I'll cut 

it on at this time. 

CC Pre launch mode. 

S/C Roger, prelaunch 

S/C .... on, over 

CC Say again Jim. 

S/C I say my computer lights on, we're ready. 

CC Roger. 



CC I think you did a smart thing back there. 
Roger. 

S/C Yeah, it would have been a short flight if we kept pushing 
that bottle around.

CC Yeah, sounds like you have been awfully busy this first couple 

of orbits^ you know. 
S/C It would have been impossible. We had never got the EVA gone 

at all. 

S/C It was and it's really nice. 

Cap Com, Cape Plight. 
CC Go ahead. 

Get him to describe his status inside the cockpit in regard to 
the equipment, what he's got hooked up and ready to go with. 
CC Okay. Hey, Jim, Jim, this is Houston. Gemini U Houston Cap 
Com. 

S/C Go ahead Houston, Gemini \. 

CC How about describing the way the cockpit is layed out now with 

all of your gear out. 
S/C Okay, Well, we've got to the get out position here and when we 

finally called it quits it was obvious that we wern't going to 

make it at that time without really rushing, and I didn't want 

to do that. 
CC Roger. 

S/C Roger. He has most of the equipment on him right now. I've 
got the gun and the camera and the hatch fitting, the fitting 
to couple the two suit hoods together with, that is all the 

parafinelia on him right now, hut he is on suit circuit, got 
the repress valve off, and we are just about all set to go. 
I think that when we get right over Africa, we are going to go 
through the checklist again, and when we get to Canarvon, we

will be all set, 
CC Roger, Have you taken any pictures yet? 
S/C No, as a matter of a fact, we really haven't had time to 

CC Okay, you haven't had any time yet, have you. 
S/C It is a nice spacecraft though, Gus. 

CC Good. Do you have the shut off valve on the chest pack closed? 
S/C Roger, it is. 
CC Okay. 

S/C Okay, we get her update then? 

Did you get any update Pete, retro? 

Yes sir. The computer works done in and the TR clock. 
Rog. 

Got that Cap Com. 
CC Roger, I got it okay. 

Cap Com, just to verify, he never started a depressurization. 

Is that correct. 
CC Gemini k. Gemini h, Houston. 

California, LOS 
CC Gemini k Houston. Gemini h, Houston. 

California is LOS.

S/C Gemini h, do you read me now. 

CC Roger, I lost you there for a minute. Say, you never did start 

to decompress, did you? 
S/C Say again. 

CC Did you ever start decompressing. 

S/C Negative, we never started decompressing. 

CC Roger, I understand. 

S/c .... this is Gemini k. I think we are right over Texas now. 
CC You say you are coming right over big T. 
S/C Roger, we are. 
CC See any of it? 
S/C .... 

S/C We are over the Gulf right now. 

CC Right over the Gulf, huh. Has your weather been good around the 
orbit? 

S/C We haven't really had time to look out 

CC Roger, can you still see the booster? 

S/C I don't even know where it is right now Gus. 

CC f^oger. 

S/C We saw it just after we 

CC You are getting awfully garbled. 

S/C Roger, I say again. We saw it when we in the darkness, but we 

haven't seen it since we got back out into the light.

S/C Roger, I got pretty warm. 
CC How do you feel now? 
S/C Fine 
CC Good, 

CC Did you guys have any water to drink yet? 
S/C Negative. 

I think the booster should be about 52 miles ahead of him and 

about 5 miles below him.

CC Jim, we figure that the booster should be about 52 miles ahead 

of you and 5 miles below you at this time.

CC Very good. 

S/C We are looking right down at the Cape now. You can see the launch 

complexes down there. It is quite clear. 
CC Hey, Jim. Gemini h. We would like for you to turn your cabin 
S^X heat exchanger on until you get ready to decompress, and fan. 
S/C Ah, roger. We are not getting hot if that is what you're worried 

about. 

CC Our cabin temperature is getting up a little. 
S/C Okay. 

S/C Cap Com, Gemini h. 

CC Go ahead. This is Houston, Go ahead. 
S/C Roger. How about turning the computer off? 
CC Affirmative. 
Turn it off. 

Don't forget to drink some water now. 
S/C Yeah, can we turn the computer off. 
CC Roger, turn the ccmputer off. 
S/C Houston, Gemini h, do you read. 
CC Roger, we read you. Go ahead. 
S/C Roger, how about turning the computer off. 
CC Roger, turn off the computer! 
S/C OKAY! 

This is Gemini Control. Houston. For the last 15 minutes you 
have listened to the conversation as the spacecraft moved across the 
United States. Apparently, we have lost signal, lost contact with 
the Bermuda Station. Three hours .and 15 minutes into the mission. 



Mission Commentary Transcript 



Tape 9. 



We apparently have lost contact with our Bermuda station at this 
time. For the last 15 minutes we have been listening to a live 
transmission frgm the spacecraft and generally, I guess it might 
be characterized as a settleing down sort of past. Jim, getting 
another transmission, another conversation from ±kH McDivit and 
Grissom. Let's go back to that conversation. 
CC Gemini h, Houston. 
S/C Go ahead Houston, Gemini h. 

CC As you come over Ascension I am going to try and give you 

a check. Air-to-groxmd hasn't worked too well today and we 
sure would like to get that one up. 

S/C Roger, we'll be waiting. 

CC Roger. 

S/C Would you advise that we've both had a drink and I had 10 12. 
CC Roger. 

This is Gemini Control Houston. . We're still getting a good 
solid W. contact from Bermuda. The voice circuit however, 
became noisy as you probably noted during that last conversation. 
The burden of it was that over Ascension the spacecraft and the 
ground will attempt a voice contact. We are interested in the 
quality of that contact which will be remoted back here from 
Ascension Island in the Central South Atlantic Ocean. This is 
Gemini Control at 5 hours and l8 minutes into the mission.

Tliis is Gemini Control Houston. Three hours and kS minutes into 
the mission. Spacecraft off the southeast coast of Africa. We have 
not acquired by oilr ground remote circuit with the Tanaverive Station, 
I repeat, we did not acquire the spacecraft. We have had trouble with 
that Tanaverie relay all morning. It did work once, it did not work 
this time. We are estimating our extravehicular activity to begin in 
approximately 35 to kO minutes from now over Hawaii. Earlier, we 
mentioned an airplane in trouble south of Bermuda. That airplane has 
now been intercepted with several other aircraft. It's estimated to 
be in Bermuda at Kinsley Air Force Base in approximately 20 minutes. 
This is Gemini Control. 

This is Gemini Control Houston k hours and 1 minute into the 
mission. The Canarvon Station in western Australia is in touch with 
the Gemini k spacecraft at this time and Command Pilot Jim McDivit 
reports the status is excellent onboard and they are prepared to 
start the jirEsax depressurization of the cabin preliminary to the 
extravehicular activity. In the last minute the - we had a blood 
pressure reading from both the Command Pilot and the Pilot. The 
blood- pressure readings came through loud and clear and they are 
quite nominal values. The sequence of events here calls for depressuri- 
zation followed by final check list, preliminary to opening that hatch. 
They are estimating that that would occur over the Hawaii station. 
Our contact should be even better on this pass then it would have been 
on the previous pass. Meanwhile, most of the flight controllers here 
have taken about a 10 to 15 minute break, they have had a sandwich and 
a cup of coffee, and they have returned to their consoles in preparation

for this important maneuver. This is Gemini Control. 

This is Gemini Control in Houston. We are still in touch with 
the Gemini h spacecraft over Western Australia, and we are prepared 
to play at that time a tape of that conversation which is still in 
progress. Let's hear the tape now. 

S/C Hello Carnarvon. Hello Carnarvon. Gemini IV. 

CC Gemini IV. Carnarvon CAPCOM 

S/C Roger Carnarvon, Gemini IV. How do you read? 

CC Loud and clear. Over. 

S/C Loud and clear. 

CC Roger. Will you turn your cabin fan off. Heat exchanger to k 1. 

S/C Roger. Cabin fan off and cabin heat exchanger to k 1. 

CC Roger. We would like a blood pressure from the command pilot. 

What is your status for EVA? 
S/C The status is GO for EVA. 

CC Okay. You are GO for EVA from here. In for decompression. 
Correction .j.. . 

. . . aepressurization. Could you give us the blood pressure 

on the command pilot? 
S/C Roger. I'm going to try to give you a blood pressure right now. 
CC Alright. 

Okay, keep coming. It is coming up. 

Your pulse is full scale. 

Could you give me about 10 seconds on your quanity read switch, 

please? 
S/C Quantity read is on. 
CC Roger.

Tape 10, Fa;:e 



S/C Quantity read is on. 

CC Roger. Okay we got a good blood pressure from you. Now, your 

right secondary 0^ should be open. Your left secondary 0^ should 
be closed. 

S/C Affirmative. That's the configuration. The left is closed the 
right is open. I understand we have a GO to start the decom- 
pression. Is that right? 

CC That's affirmative. GO for decompression and a GO for EVA. 

S/C Roger. I expect to be out ... .1 will call near Hawaii. 

CC Roger. Very good. 

CC Flight, Carnarvon. 

FLT Go ahead. 

CC Okay. You got anything you want to pass to them. 
FLT Negative. 

CC Okay. I'm going to cut off the conversation to them then. 
FLT We would like to have the quantity switch to read throughout 
the pass, starting now — 



Mission Commentary Transcript EVA-1 

This is Gemini Control. Four hours and 24 minutes into 
the mission. The Hawaii station has just established contact 
and the pilot Jim McDivitt advises the cabin has been depres- 
surized. It is reading zero. We are standing by for a Go 
from Hawaii to open that hatch. Meanwhile, we've been advised 
by Flight Dynamics that the booster, the second stage booster, 
is approximately 65 miles in front of the spacecraft and about 
three miles below it. It is not known whether the pilot or 
the command pilot will be able to see it. Meanwhile Ed White 
reports he's feeling fine. And standby for a mark from Hawaii. 

This is Gemini Control. White has opened the door - he 
has stood up and it's a most relaxed period. McDivitt reports 
that White is standing in the seat. Let's hear that conversation 
live right now while is standing up in the seat - the hatch is 
open. Let's go with a live broadcast- from Gemini 4. 

CC Flight, Hawaii. 
Flight Go ahead. 
CC Emergency 02 is 3400 psi. 

Fit Roger, we copy. 
CC Roger. He is standing in the seat.

CC All systems on the ground look good. 
Flight Roger. 

S/C Our ECS is real good. It's reading still 50 percent. 
Looks like we're not even using any. 
CC We concur on the ground. 
S/C Hell, Hawaii, hello, Hawaii 
CC We understand. 

Flight . . you're having him get out? 

CC Roger, flight, we're go. He's got some nice elevated 
rates which we expected and he's really speeded it up but he 
looks great - let's go (This transmission was from the Flight 
Surgeon . ) 

Flight Hawaii, Houston. 

CC Houston Flight, Hawaii Cap Com. Go. 

Flight Tell him we're ready to have him get out when he is. 

CC Roger, I understand. 

Flight Tell him to give us a mark. 

CC Gemini 4, Hawaii Cap Com. 

S/C Come in, Hawaii, Gemini 4. 

CC Roger. We just had word from Houston we're ready to have 
you get out whenever you're ready. Give us a mark when you 
egress the spacecraft. 



'I'ape 11 

Mission Commentary Transcript EVA-3 
S/C Okay we've got our Go now - is that right? 
CC Affirmative. 
S/C Ok . 

CC Be sure and give us a mark when he egresses. 
S/C Ok. We're still doing a little work right here. 
CC Roger, understand. 
Flight Get his status, Hawaii. 

CC Hawaii Cap Com, what is your status now? 

S/C We're about ready to start getting out. Ed just got one 
of his gloves back on and he'll put another one on and we're 
ready to go. 

CC Can you repeat Gemini 4? 

S/C He's ready to egress right now. 

CC Gemini 4, Hawaii Cap Com. Can you repeat your last trans 
mission. 

CC Gemini 4, Hawaii Cap Com. Do you copy? 
CC Gemini 4, Hawaii Cap Com. Do you copy? 

This is Gemini Control, Apparently the spacecraft has 
lost contact. The Hawaii station advises that "I think the 
last transmission was 'He is getting out right now' at 45 
past the hour. Very shortly after that transmission we had 



Tapo 11 

Mission Commentary Transcript EVA-4 
loss of sight. Gus Grissom, Cap Cora here, isn't so sure that 
that was the burden of the message. It'll be several minutes 
before we can establish whether he did leave the spacecraft 
at that time or not. In any case, he was feeling good. The 
surgeon was entirely satisfied with what he was reading and the 
weather over the United States looks like it's going to cooperate. 
The weather in the southwest is clear over Arizona . Moving 
farther east, partly cloudy over Texas and Louisiana, scattered 
clouds over Florida. So, in general, the viewing while White 
is out in space over the United States should be excellent. We'll 
stand by for a recontact with our California station in perhaps 
two minutes. This is Gemini Control at four hours and 31 minutes 
into the mission. 

This is Gemini Control, Houston. Gus Grissom has just 
established contact with the spacecraft. McDivitt confirmed 
that White did leave the spacecraft. He said he looks great. 
He's outside working his maneuvering unit and Jim is quite 
exuberant about the performance that he's witnessing at this 
time. Let's cut in live now and listen to what White says. 
We've not heard him say anything over his comm loop, but let's 
tune in on that conversation. 

This is Gemini Control. The voice you hear repeating 



i'ape 1 1 

Mission Commentary Transcript EVA-5 
"It's working - keep talking there" is Jim McDivitt - 
CC Tell him to keep talking - we're receiving Ed through 
your VOX. 

S/C Ok. We'll go to VOX then. Ok, Ed, they're receiving us 
Tell them what you think. 

White: Cap Com, the maneuvering unit is good. The only problem 
I have is that I haven't got enough fuel. I've exhausted the 
fuel now and I was able to maneuver myself down to the bottom 
of the spacecraft and I was roght up on top of the adapter. 
. . . Jim and came back into his view. The only thing I am . . 
. . . Over my head and I'm looking right down and it looks like 
we're coming up on the coast of California. And I'm going in 
slow rotation to the right. There is absolutely no disorient- 
ation association. 

S/C One thing about it when Ed gets out there and starts 
whipping around it sure makes the spacecraft tough to control. 
CC Is he taking pictures? 

S/C Of the ocean. This is only my guess. He took the first 
one . 

CC Take some pictures. 

White: I'm going to work on getting some pictures, Jim. 



Tape 11 

Mission Commentary Transcript EVA-6 

S/C Ok. Get out in front where I can see you again. 

I've only got about three in the Hasselblad. 

White: Ok. 

S/C Where are you? 

White: Right out in front now. I don't have the control I had 
any more . . 

CC And you've got about five minutes. 

Wlhite: I want to get out and shoot some more pictures . . . 
S/C Ok. I'm going to start firing the thrusters now. 
White: There's no difficulty in recontacting the spacecraft. 
It's all very . . . particularly in trying to move back . . 
I'm very thankful in having the experience to be first. Right 
now I'm on top of the . . . the window. I pulled myself in 
and put myself in . . 

S/C Move slowly and I'll take your picture. 
Haney: Can he see the booster, Gus? 

White: Right now I could maneuver much better if I just had the 

gun but I'll manage. . . 

S/C Ok. Stay right there if you can. 

This is Gemini Control, Houston. . . Here they are again. 
S/C Ed, will you please roll around. Right now we're pointing 



Tape 11 

Mission Commentary Transcript EVA-7 
just about straight down to the ground. 

White: Ok, now I'm taking a look back at the adapter -I'm 
looking back there. Couldn't see . . . The thrusters are 
clean. The sun in space is not blinding but it's quite nice. 
Also the Velcro that we put on seems to be in good shape. . . 
I'm coming back down on the spacecraft. I can sit out here and 
see the whole California coast .Looking on further out . . . 
Flight, this is Surgeon. The data looks great here. 
Flight: How's his EKG? 

Surgeon: It looks great. Flight. He's just ripping along 
here at a great rate. 

This is Gemini Control, Houston. Here on the ground we're 
watching a scope of the heart action and respirations. 
S/C For your information, Ed, we're only down to 48 percent on 
our 02. And the ECS 02 pressure is about 830 so it's staying 
right up there. 
White: . . 

S/C Oh, yeah, is that right? Where it's attached to you or 

where it's attached to the spacecraft? 

White: Where it's attached to the spacecraft. 

CC Gemini 4, this is Houston Cap Com

White: I'm looking right down your gun barrel, huh? All 
right . 

S/C Let me take a close-up picture of you. 

S/C You smeared up my windshield, you dirty dog. You see how 
it's all smeared up there. 
White: Yep. 

S/C Looks like there's a coating on the outside and you've 
rubbed it off. That's apparently what you've done. 
CC Gemini 4, Houston Cap Com. 

S/C The spacecraft rates are up about one degree per second in 

pitch and yaw and about a half degree per second in roll. 

S/C Ed, I don't even know exactly where we are but it looks 

like we're about over Texas. 

CC Gemini 4, Houston Cap Com. 

S/C As a matter of fact that area looks like Houston down 
below. 

CC Gemini 4, Houston Cap Com 
S/C Hey, Gus, I don't know if you read us but we're right over 
Houston . 

White: . . . we're looking right down on Houston.

see it on your side of the spacecraft. 

White: I'll get a picture. 

S/C Can you see the camera here? 

White: Yeah. 

S/C Is it pointing at you. 
White: No, Not now. 
S/C Which way. 

White: . . .I'm not getting a picture. 

S/C Now don't get back there where the - 

White: I'm right behind you and right above where . .

White: . . . 

S/C That'll really be it, huh? 

White: Yeah. 

CC Gemini 4, Houston. 

White: .... of the Texas ... I only shot about three or 
four . 

S/C Is that right? Well, I've taken a lot but they're not 
very good. You're in too close for most of them. I finally put 
the focus down to about 8 feet or so . 
CC Gemini 4, Houston, 



Tape 11

S/C You know, Ed, this thing about the reference we were 
talking about looks like it's sure right.

Flight: The flight director says get back in. 
S/C Gus, this is Jim. Got any message for us. 
CC Gemini 4, get back in.

White: The spacecraft really looks like it's . . .. because 



Tape 11

whenever a piece of dirt or something goes by it always heads 

right for that door and goes on out. 

S/C Ok - whoops, take it easy now. 

White: Ok. I'm on top of it right now. 

S/C Ok, you're right on top. Come on in then. 

White: The hand hold on that spacecraft is fantastic. You ca 

really .... Aren't you going to hold my hand? 

S/C No, come on in the . . . 

S/C Ed, come on in here. 

White: All right. 

S/C I'll put the gun up. 

White: I'll open the door and come through there. 

S/C Ok. Let's not lose this camera now. I don't quite have 

it. A little bit. more. Ok. I've got it. 

White: . . 

S/C Yeah, we sort-of talked about that - 
White: Huh? 

S/C We sort of talked about that didn't get very much of a 
chance . 
White: No.

S/C Well, you're going to find it sadder when we have to 

come down with this whole thing .

S/C Ok. Come on now. 

CC Gemini 4, Houston Cap Com. 

S/C Let's see you get those hand dogs fixed now. 
CC Gemini 4, Houston Cap Com. 

S/C I'm just putting all this stuff down here . . . 

I'm going on in a minute. No time to talk now - I'm pulling in 

his air hose. Ok. Any messages for us Houston? 

Flight: Yeah, get back in. 

CC Are you getting him back in? 

S/C Yeah, he's standing in the seat now and his legs are down 
below the instrument panel. 

CC Ok, get him back in. You're going to have Bermuda LOS 
in about 20 seconds . 

S/C Ok, he's coming in. He's having some trouble getting 
back there in the spacecraft. 

CC Are your cabin lights up bright in case you hit darkness? 

This is Gemini Control, Houston. We apparently have lost 
the signal in Bermuda after an extraordinary 20-minute conversation 



?ap«; 1> 

Mission Commentary Transcript EVA-13 
with Pilot Jim McDivitt and Ed White. The reason for the 
delay in receipt of the signal from Houston was, of course, 
that McDivitt had his key so - in a position so that he could 
not receive the signal up here. No great concern on the ground. 
The conversation was certainly stimulating and we are assuming 
by now, at last report we have Ed down in the seat and we're 
assuming by now that they're about to close the door on that. 
And We're now hearing McDivitt again. 

S/C . . especially what kind of pictures we had there - . . 
CC Roger. 

Flight: What did he say, Gus . 

CC That he was busy and would rather not talk to us. 

This is Gemini Control, Houston. We have lost signal 
with Bermuda. At our last report, McDivitt was - everything was 
going along all right. We're standing by right now. We expect 
to get a cue from the Flight Director as to when we'll next 
depressurize and open the spacecraft. This is, according to 
our original plan, in order to jettison some of the bulkier 
gear. Among theitems to be discarded in space are the chest 
pack, the emergency chest pack that Ed used, the space

This is Gemini "Control Houston. We are 5 hours and 10 minutes 
into the mission. To review for you the times, approximate times of 
the extravehicular activity of Major White. We estimate here that 
the hatch was open, the right hatch was opened at h2 minutes after 
the hour. We have a time hack on his, his actual pushaway from the 
spacecraft at U5 minutes after the hour. He was back in and standing 
on the seat at 5 minutes after the hour, some 20 minutes after he 
left the spacecraft. We have not had an approximate time of closure, 
however. Ascension was reading the spacecraft on some telemetry 
channels. They did not raise it hy voice as it passed over that 
station a very few minutes ago. Right now, its approaching the 
Tanarive Station and then we also have a station which may or may 
not be able to raise it at Pretoria South Africa. The next major 
discussion we can look from for is the Carnarvon Station, some 8 to 
10 minutes from now. The spacecraft is in a darkside right now. 
Our data here shows approximately 2 pounds of fuel, 2 pounds of fuel 
were used to maintain attitude during the extravehicular activity. 
The mission seems to be proceeding very nicely at 5 hours and 11 
minutes in. This is Gemini Control Houston. 

This is Gemini Control Houston. 5 hours and 31 minutes into

was from Ascension. We did not establish voice contact there. 
Everything from that point was fairly optimfstic. We still are unable 
to supply a precise time on hatch closure, however, we have the 
Carnarvon station coming up with communications from Carnarvon have 
been excellent all day. We have a report that both Mrs. McDivit and 
Mrs. White are in route to the Control Center now. They plan - this 
is a little unscheduled visit. I think they want to stop by and 
shake a few hands with some people here who followed the — this 
extravehicular .activity very closely since t - fcx ta rxt^ g rxteH gl r mlHgx 
it's beginning. This is Gemini Control at 5 hours and 52 minutes 
into the flight. 

Ihis is Gemini Control Houston. Within the last minute we 
have established contact with the Gemini k spacecraft at Carnarvon. 
Jim McDivit 's first words were "Hello Carnarvon, nice to have some- 
one to talk to again". He apparently noted the long blank in the 
network also. He advised us that the cabin has been repressiurized 
and holding nicely at 5.1 psi. He has been given an update and a go 
for at least a 6 revolution flight which is his next nominal landing 
point should anything develop between now and then. I emphasize 
that this is just a routine update. All of the values we have heard 
sound entirely nominal. We want to stand by and listen to additional 
discussions. Hils Is Gemini Control at 5 hours and 55 minutes.

This is Gemini Control, Houston, five hours and 44 minutes 
into the mission. We've just completed a conversation between 
the Gemini 4 spacecraft and the Carnarvan station. And during 
the course of the pass, Jim McDivitt advised that the cabin 
had repressurized to 5.2 pounds. He advised that he had elected 
not to depressurize, as had been called for in the earlier 
flight plan. He didn't pass along a reason. The best guess here 
in the Control Center is that they probably decided that they'd 
like to keep the equipment as a souvenir. He did indicate they 
were going ahead and stowing the gear and he also advised that 
they could see the booster flashing some 60 miles away. We have 
re-racked that tape for you and we're prepared to play it for you 
at this time. This is Gemini Control.

CC Roger, 4. How far do you think it is? 

S/C I really can't tell. It's — looks like it's about five 
or six miles perpendicular to our flight path. Maybe it's more 
than that. It could be as far out as twenty miles perpendicular 
to us . 

CC Roger. Is your adapter C-band in command now? 

S/C Roger. It is. OK. It looks like I'm ready to turn it off. 

S/c Flight, Carnarvan.

Fit Go ahead. 

CC The only thing that didn't work properly is I'm not sure 
whether I got that beacon off. It's in command. I tried to 
turn it off and just then I had telemetry LOS so I don't know 
whether it went off - I don't - I didn't get a map deck. 
Flight Roger. I understand. 

CC But no telemetry. Everything else went normal. And he 
sees the booster out there, but he doesn't know whether it's 
five or six miles or twenty miles — it's perpendicular to his 
flight path. 

Fit Rog. We copied everything. Good pass. 
CC Roger. That's affiinrv. 

This is Gemini Control, Houston. We are six hours and 
five minutes into the mission. We've just had a short discussion 
with the Gemini 4 spacecraft over Hawaii. It was very brief, on 
the order of less than a minute. It did develop in that 
discussion that there was apparently some small difficulty 
in closing the hatch. It was not described in any detail, 
and we had asked the spacecraft for a hatch closure time. They 
said they'd figure it out and advise us. They did advise 
that Ed White discarded one of the thermal gloves - protective 
gloves - that he was wearing. He also discarded a gold over- 
visor that he wore while outside the spacecraft. The systems 



Mission Coiranentary Transcript Tape 14, Page 7 

report from Hawaii v/as excellent. All the spacecraft systems 
functioning very nicely. The cabin pressure holding nicely 
at 5.2. Meanwhile, both Pat McDivitt and pat White, the wives 
of these two pilots, are here in the control center. They've 
been here approximately a half hour. They have been chatting 
with Dr. Gilruth and with Congressman Casey. This is Gemini 
Control at six hours and seven minutes into the mission. 

This is Gemini Control, Houston, six hours and fourteen 
minutes into the mission with the spacecraft moving across 
the south central United States. It's been an unusually 
quiet pass to date, due largely to the fact that Jim McDivitt 
has been taking an oral temperature and, therefore, has stayed 
off communications. The communications, themselves, have not 
been the best. We don't know whether we have a problem in our 
ground site remoting or whether we have a problem in the space- 
craft. We plan to work both ends of it in an attempt to clean 
up communications. When we do have them, they're noisy, and 
we attempted during the earlier part of this pass to go to 
using the high frequency communications system via California. 
That was an extremely weak and unreadable signal. We're back 
on UHF now. We can hear McDivitt, but it is just barely 
intelligible. This is Mission Control, Houston, six hours and 
fifteen minutes into the mission.

This is Gemini Control Houston. We are 6 hours and 21 minutes 
into the mission. In this pass across the states, we read out medical 
values onboard, our flight surgeon here in Houston has been in direct 
conversation with both the Command Pilot and the Pilot. One of the 
more interesting aspects of th-^ ^--r.y- i ;.;aLion was n ■■ ' ' ■ 
Dr. Berry as to whether Ed White had any disorientation while he 
was extravehicular. White came back very strongly that he had 
absolutely no disorientation. He, in fact said that marvel^'l at the 
fact that in no matter what position he seemed to assume, or what 
kind of whirl he went into, he was at no time disoriented. He has. 
White, that is, has been advised as to go to sleep for about a h hour 
period. Jim.McDivit, meanwhile, who sounds a little sleepy too, has 
advised that he will pick up the flight plan as it existed and begin 
to begin to program his fuel against his various experiments. This 
is Gemini Control at 6 hours and 22 minutes into the mission.

This is Gemini Control. We are now 7 hours and 59 
minutes into the mission. Voice communication with the 
spacecraft was" made within the last hour between the tracking 
ship Coastal Sentry Quebec and through the Houston communica- 
tions center here, talking to the spacecraft through the 
Guaymas and California stations on a remote loop. While the 
spacecraft was talking to the CoaslslSentry Quebec , that 
tracking ship gave the spacecraft commander a Go for 18 
revolutions. McDivitt said his spacecraft was in a Go 
condition. The tracking station advised Jim that he looked 
very good. At that time McDivitt also made a medical pass 
and a blood pressure reading was obtained. Here at the 
Gemini Control Center in Houston everything has calmed down 
after the EVA. Plight Director Eugene Kranz anticipates no 
additional maneuvers will be needed to maintain our four 
day orbital lifetime. At the present, the spacecraft is 
orbiting at approximately 185 statute miles apogee and 103 
statute miles perigee. The fuel remaining aboard the 
spacecraft is greater than anticipated since we scrubbed 
the rendezvous exercise. The oxygen consumption is normal.

brushed against the glass window of the spacecraft and they 
want to see if anything brushed off with it.

At this time the spacecraft is over the Indian Ocean and we are 
into a quiet period of the flight. Pilot Ed VThlte Is sleeping. 
Spacecraft commander Jim McDivitt is guiding the spacecraft and 
coiiiraunicating with the ground at long intervals in between. To 
sum up our situation the Gemini TV spacecraft has been given a 
GO for 18 revolutions. McDivitt has reported that he and Ed White 
are in a GO condition. The oxygen and fuel supply are in good 
quantities aboard the spacecraft and at this point in the flight 
everything is GO. This Is Gemini control. 

This is Gemini control. We are now 9 hoiirs and I9 minutes into tlie 
mission. Hie Gemini VI spacecraft is passing over the Pacific bcca:i 
on the day side of the world. It is in the sixth revolution. Fllgi.t 
surgeon Dr. Dwayne Catterson reports that thus far the medical read- 
outs on the flight crew look real great. Pilot Ed White is still 
asleep. Dr. Catterson reported that White ate some bacon and egg 
bites, toast and orange juice before going to sleep. Both astronaulrj 
have taken water. White did not coirrment on the food. We had com- 
munication with the spacecraft at 8 hours and 57 minutes into the 
mission, while it was over the Coastal Sentry Quebec, in the Pacific 
Ocean. At that time the Coastal Sentry Quebec updated landing area 
times for the flight crew. The Coastal Sentry Quebec also reported 
that all spacecraft systems looked good. Flight Director Gene Kranz 
has just ordered a halt to voice communications with the spacecraft

because its position relative to the ground tracking stations on thl." 
pass makes comraunications difficult and he wishes to spare the flitf''t. 
crew this difficulty. Thas Is Gemini control. 

This is Gemini control. We are now 9 hours and 38 minutes into the 
mission. At the present time the spacecraft has just passed over the 
Rose Knot Victor, the tracking ship located off the east coast of 
South America. During this pass, the Rose Knot Victor comnninicator 
passed on an updated flight plan for the crew. He advised the com- 
mand pilot to start his sleep period at 11 hours into the flight. 
That Is approximately 1 hour and ^ from now. ■ And to sleep for ap- 
proximately k hours. He also instructed the pilot to give a medical 
pass — type one — at the time the command pilot would be starting his 
sleep period. We have had very little voice communication with the 
spacecraft. In fact, until this communication with the Rose Knot 
Victor we have been out of communication for at least minutes. 
Communication has been difficult due to the elevation and angles at 
which the spacecraft is passing over the tracking station. _And for 
this reason Flight Director Gene Kranz has ordered that voice com- 
munication with the spacecraft be kept at a minimln. Ihis Is Gemini 
control.

•| hour. At this time the spacecraft is over the Indian Ocean and ic 
abcut to come up on another sunrise. Flight Director Gene Kranz is 
starting the flight crew back. on the regular flight plan. He has 
programed times for measurements of outside radiation and of the 
earth's magnetic field relative to the spacecraft. He has also 
programed the experiment to measure radiation inside the spacecraft. 
The first experiment designated D-8 will be made approximately 1 h(.>ur 
from now. The latter two designated MSG 1 and 2 commence in apxjro/:;.- 
mately 2 and ^ hours. Flight surgeon Dr. Dvayne Catterson reports 
that all the medical data he; has received looks perfectly normal at 
this time. Mission Director Chrisphor i^aft has just returned to

Tliis is Gemini, control. We have not had 

communication with the flight crew for approximately 1 and l/2 hours. 
However, we expect to be contacted by voice from the Hawaian tracking 
station within moments. Flight Director Gene Kaanz has ask the 
Hawaiian station to conduct a UHF communications check with the space- 
craft. He also asked them to use a minimiim amount of spacecraft 
fuel for this check. Delayed time telemetry will also be relayed 
.from the spacecraft to the ground station. Passing over the Coastal

a tracking ship located off the east coast of Pueru, South America. 
The Rose Knot Victor is giving the flight crew block updates for 
landing areas in 6 orbit increments. Pilot Ed White has completed 
his sleep period and he has given the ship's flight surgeon a blocjd 
pressure check for aeromedical type pass I. This also included an 
cra^l temperature check and he used the bungee cord exerciser. Ttiis 
was followed by another blood pressure check. Pilot Ed White also 
gave a report on food, water, and sleep. He said he woke up about 
20 minutes ago. He did get some sleep but not a soxind sleep. His 
report on food and water intake was not clear and we did not get- a 
good report on that. This is Gemini control.

the handle back and forth. One of them is the gear that sorca 
acts as a ratchet - a little filter with a system in it 
that engages this ratchet. We had a little trouble with that 
before we got it open. After we got it open we had difficu3.ty 
in getting this ratchet to work. Also, we had a great deal of 
difficulty in getting the hatch to close far enough so that we 
could even start ratcheting it. We had to point the ratchet in 
with our hand on every go until we got it started. We pulled

This is Gemini Control, I8 hours 59 minutes after lift-off. Hie Getiiliii h 
'^is presently over the South Pacific, Just east of New Zealand. The next 
station contact will be in I3 minutes when voice and telemetry will ayttin 
be acquired from the tracking ship. Rose Knot Victor. No voice contact 
has been made with the spacecraft since the pass over the Rose Knot Victor 
at the end of the 11th revolution. This is Gemini Control. 

This is Gemini Control. It is now I9 hours 9 minutes after lift-off, 
beginning of the 15th revolution. Gemini k spacecraft -is now in the 
Atlantic, north of Trinidad. During the pass over the tracking ship, 
Rose Knot Victor, beginning about I6 minutes ago, the crew received retro- 
fire times for several of the next planned landing areas. This is a routine 
procedure and allows the crew to make a closed-loop reentry should it 
become necessary. Retrof ire updates are routinely passed up to the ci-ew 
at intervals. The Rose Knot Victor CAPCOM reported that the spacecral't 
systems all looked good on the telemetry readouts. The Rose Knot Victor 
will have a respite until the 21st revolution. Next contact will be with 
the Canary Islands tracking station 6 minutes from now. This is Gemini 

Control. 19 minutes after lift-off. We how have a tape 

recording of the recent pass by Gemini k spacecraft over the Rose Knot 
Victor in which retrofire times for several planned landing areas were 

routinely passed up to the spacecraft crew to allow them to make a closed- 
loop, reentry should it become necessary. Retrofire updates are routinely 
passed up to the crew at these intervals. The tape follows.

This is Gemini Control. It is now 19 hours and 30 
minutes after liftoff. The Gemini 4 spacecraft is now 
over the Indian Ocean just west of India. The spacecraft 
is in an orbit, with a perigee of 101 statute miles and a 
apogee of 179 statute miles. Communications during the 
last pass over the Canary Island tracking station were 
quite good. The next tracking statj.on to make contact with 
the spacecraft will be the Canarvon, Australia station 12 
minutes from now. This is Gemini Control. 

This is Gemini Control, 19 hours, 46 minutes after 
liftoff. We now have a tape recording between Gemini 4 
spacecraft and the Canary Island tracking station during 
the 13th revolution. The figures given between the CapCom 
and the spacecraft crew on the apogee and perigee of the 
orbit are in nautical miles. To get statute miles you need 
to add about 15 percent. This is Gemini Control, the tape

This is Gemini Control Houston, 21 hours and 39 minutes 
into the mission. The spacecraft just passed over the 
Canarvon Station which we had a rather lengthy discussion 
with Pilot Ed White. White reported among other things that 
he had had a very sound sleep earlier, he said Jim McDivitt 
is asleep at this time. He reported his cabin pressure at 
5.7 psi and he reviewed other quantities which looked 
very favorable - oxygen, for instance, he uh, had at least 
40 percent supply left which is slightly above what had been 
programed. The Mission Director Chris Kraft is considering 
at this time ordering the Gemini 4 crew to return to the 
flight plan as laid out, until, at this particular time. 
Uh, that is, he's going ahead with the normal oms usage, etc. 
He feels that we, uh, from all the information collected 
during this first day of flight, that, uh, we have enough 
reserve to continue with the flight plan as originally 
laid out. This is Gemini Control at 21 hours and 40 minutes 
into the mission. 

This is Gemini Control Houston. Twenty two hours and 
8 minutes into the mission with the spacecraft moving across

of Perth, He has been advised -to follow .the normal flight 
plan with all the maneuvering .During the night the pilous 
among other things, photographed, took several pictures of 
Typhoon Carla . At this time we have racked up the tape on 
the Bermuda conversation and we'd like to play it for you. 

Here's the tape.

CC: Okay, the last thing I tried to get to you before I 
lost you just a few seconds ago was that, the, uh, be 
judicious in the use of your fuel. We think we've got 
enough to complete the whole flight plan now. 
S/C: landmark sightings.

that 92 miles away and you're only about 114 miles high at 
that time.

for it and we won't use much fuel. Looks like Jim's pretty 
corked off for now, he hasn't stirred for the last hour and 
a half .

This is Gemini Control 25 hours ^t-O minutes into the mission. The 3;jticr.'- 

craft is coming across Central America at this time, and we have just 

sent a command out to turn telemetry on and we should be In contact with 

tlie spacecraft momentarily. We have a report from the weather man that 

the weather over the state should make for very good viewing from the 

spacecraft. The California coast only fair is the forecast, but as we 

move east it gets better. The weather man says that the viewing over 

Florida, for instance, should be very good. In the Gulf area, partly 

cloudy, but it should make for good viewing. Meanwhile out in the i^acific 

the typhoon babe, which we have heard so much about the last few days, 

has downgraded to a tropical storm. It is over Shanghai at the presorrc 

time with winds of about UO knots. We have a report also on what waG; 

typhoon Carla. It is no more and was downgraded during the night to a 

tropical storm. It is something less than a tropical storm at this time. 

Neither of those systems are going to present us with any trouble. V/e 

have been looking at an electrical usage curve here in talking with our 

guidance navigation control officer about it, and in his words were fat 

on electrical power. The curve shows that at this point we thoueJi w.j 

would have had about 1700 amp hours remaining and as a matter of fact 
have _ 

ve /better than loOO amp hours remaining. This is Gemini Control at 

23 hours and k2 minutes into the mission. We still have not established 

contact, but we will momentarily and will be back with you when we do.

This is Gemini Control Houston, 24 hours, 10 minutes 
into the flight on the 16th revolution, with the spacecraft 
southeast of the Kano, Nigeria station. The current elements 
for our orbit are as follows: 178 statues miles apogee, 178 
statue miles apogee, 102 miles apogee, that statute. Our 
information is 32.56 degrees to the equator. The period of 
each revolution is one hour, 34 minutes, and 20 seconds. One 
hour, 34 minutes, and 20 seconds. In the last five minutes 
we've been in conversation with our fli-ght surgeon. Dr. Berry, 
and he passes along the following information on the sleep 
and eat cycle of these two men. Ed White slept XXiX lightly 
from 6 hours and 30 minutes into the mission to 10 hours and 
30 minutes into the mission. The sleep was described as 
little more than dozing. He was then awatefor 5h hours 
at which time he went back to sleep for a four hour period 
and at least the first part of that period which extended 
from 16 hours in to 20 hours, was described as a deep and 
restful sleep. We know that White has eaten at least two 
KiiXK meals and probably more. Each pilot has drunk about 
a pint and a half of water which, uh, appears to Dr. Berry 
to- be quite an adequate consumption. Jim McDivitt slept 




Mission Conunentary Transcript Tape 25, Page 2 

and again his first sleep period was described as a light 
one. He went to sleep at 11 hours and 15 minutes into the 
mission; he awakened at 15 hours and 30 minutes in. He was 
then awake for five hours, he went back to sleep at 20 hours 
and 30 minutes elapsed time and awoke up a few minutes ago 
after a good solid 3 and a half hours XX sleep. Jim also 
has had two meals. Neither man at this time has had a bowel 
movement and Dr. Berry says this is expected. It is the 
result of the low residue diet they were on prior to the 
flight. He said it would not surprise him if neither had 
a bowel movement today. Perhaps it might be tomorrow before 
we, uh, either has one. This is Gemini Control at 24 hours 
13 minutes into the mission.

Mission Conunentary Transcript Tape #26, Page 

This is Gemini Control Houston, 24 hours and 40 
minutes into the mission. Some 8 minutes ago the Canarvon 
station acquired the spacecraft; a very brief discussion 
ensued with the pilot Ed white; he said everything looked 
fine, and the Capsule Communicator at Canarvon ass\ared 
him that everything looked just as good on the ground. 
The flight plan for this next revolution calls for, or 
for the last part of this 16th revolution, calls for a 
medical update over Guaymas. We will do some HF checks 
during the next hour or two and we are having the flight 
plan marked for us now so that we can barely read it. 
All in all everything is moving along very nicely. The 
spacecraft directly over Australia at this time. This 
is Gemini Control out at 24 hours and 41 minutes into ■ 
the mission,

Mission Commentary Transcript Tape #27, Page 1 

This is Gemini Control, 25 hours and 12 minutes into 
the mission. In the last minute we've established contact 
with our Guaymas station with the Gemini 4 spacecraft. Earlier 
we had reported that Jim McDivitt.was awake. We had reported 
that he awoke about 24 hours into the mission. That report 
was in error. He has continued to sleep, he's been asleep 
a little more than 5 hours, apparently very deep and restful 
sleep. We've been centring notes with the ECOn Environmental 
Control Officer here in the Control Center, and he advises 
that we have about 35 pounds of oxygen remaining. That is 
out of a total... we lifted off with about 50 pounds of 
breathing oxygen on board. He tells me that the pilots used 
a little over 9 pounds in performing the extravehicular 
activity yesterday. Their normal consumption rate is 2.2 
pounds per day, per man. This gives us plenty of pad on 
the oxygen department. We also have in the spacecraft ... 
we lose about one pound per day in leakage and this is the 
acceptable value on that. With the spacecraft coming across 
the, uh... Mexico at this time, let's cut in and see if 
Ed white has anything to say for a live transmission. Stand by. 
NOTE: a Audio unable to pick up this transmission. 



Mission Commentary Transcript Tape #27, page 2 

This is Gemini Control, Houston. 

Live transmission. We've moved across the 

United States and you may have missed the last portion of 
that, we're still receiving. Stand by. We're right on the 
tail end of what will be the last transmission from Bermuda, 
the circuit is getting noisy and ragged. You probably heard 
McDivitt report that he had not slept particularly soundly. 
He dozed a bit and he advised that when there is radio 
contact he can't get his radio all the way down - it's designed 
that way and it does make for a rather fitful sleep, apparently.

This is Gemini Control at Houston, 25 hotirs and 39 minutes into the 
Mission, The spacecraft some 600 to 700 miles south of the Kano Nigeria 
Station. During the next hour and one-half, the Gemini h crew will perform 
at least three checks of their HF radio transmitting equipment. This 
system is not used for normal flight mission activity. It is used, however, 
during reentry and close to the water in the recovery process. Uie primary 
mode of communication voice communication during a flight is UHF. We 
had a marginal contact with the Gemini k spacecraft a few minutes ago 
at the Canary station. It was rl^t on the outer edge of the Canaries' 
contact capability. It was not a long transmission, a very brief sort 
of contact at which time an update time was passed up to the pilot on one 
of the HF checks. Everything moving along very nicely, 25 hours and kO 
minutes into the mission. 



Mission Commentary Transcript Tape #29, Page 1 

This is Gemini Control at 26 hours and 9 minutes into 
the flight. At this time the spacecraft is in contact with 
the Canarvon Station. The medical quantities are being 
reviewed, the command pilot has just performed a blood 
pressure check and they are being queried now on their food 
and water consumption. The flight seems to be progressing

This is Gemini Control Houston, 26 ho\irs kl minutes into the mission. 
We have just lost contact with the Hawaii station in a brief pass there, 
but a most interes'ting pass. I mentioned earlier that Pat McDivitt and 
Pat White entered the control center about 15 to 20 minutes ago. In the 
course of chatting with Mr. Chris Kraft, he asked them If they would like 
to talk to their husbands during this pass across the United States. They 
both eagerly accepted the offer, and they are down on the floor of the 
Control Center at this time prepared to talk if communications are solid. 
The conversation will probably await until the latter portion of the 
pass. We should be in contact with the California station momentarily. 
We have not yet established it. This is Gemini Control.

In the last few minutes here in the Control Center, we have had a most 
unusual occurrence, Pat McDivitt and Pat White came down on the floor. 
They plugged into the mission director's console and had an extraordinary- 
chat with their husbands. They very kindly consented to share that con- 
versation with us, and we are prepared to play that tape for you right

This is Gemini Control, Houston, 27 hours and 30 minutes 
into the mission, on the 18th revolution. From Carnarvan, we've 
just had a report that they've skin-tracked with the radars the 
second stage of the Gemi-^i launch vehicle. They report that 
it's running some 4 minutes and 10 seconds ahead of the space- 
craft. We have no elements available on the orbit the second 
stage is in at this time. Meanwhile the two Pats, Mrs. McDivitt 
and Mrs. White, are still with us here in the Control Center. 
They've been in an animated conversation with Dr. Berry, our 
Flight Surgeon, and Mission Director, Chris Kraft, for much of 
the past hour. They seem delighted with the progress of the 
flight, as their conversations with their husbands indicated. 
Jim Lovell has also joined the group here. Jim Lovell is the 
backup pilot to Ed White on this mission. Meanwhile, Ed White 
should be sleeping at this time. He's due for a two-hour sleep 
at this period. We do not know whether he's taking advantage 
of it or not. He's been awake for seven hours. In the next 
pass over the United States, Jim McDivitt will perform what we 
call an M-3 experiment; that is, he will use the inflight 
exerciser. The exerciser is a rubbery, or a bungee, cord affixed 
to the floor of the spacecraft. Each crewman pulls the cord 
at the rate of one pull per second for about 30 seconds. Each 



Mission Commentary Transcript Tape 32, Page 2 

crevmian exercises in conjunction with an aeromedical pass 
over a ground station, in which readouts are made of oral 
temperature and blood pressure. The astronaut then exercises 
with the exerciser and again inflates the blood pressure cuff 
for a ground station readout. The two crewmen use the exerciser 
three times daily, additionally, without an aeromedical pass. 
And, as we've been talking, the Carnarvan station sounds as if 
it has acquired the spacecraft. The contact was a slightly 
unintelligible one - a lot of noise on the circuit. But 
momentarily, they should be in good voice contact as the Gemini 
craft will go almost directly over the Carnarvan station. This 
is Gemini Control .

This is Gemini Control, Houston, 28 hours 9 minutes into the mission. 
Within the last minute^, the spacecraft has come in solid contact with the 
Hawaii station. It is directly over the Hawaii station. However, we have 
had no conversation between the pilots and the ground at this time. That 
circuit out there today is quite clean. We are standing by trying to 
monitor to see if there is any conversation coming in. We have heard none. 
Ihe Hawaii CAPCOM has called, but the pilots are obviously otherwise 
occupied. This is Gemini Control. 



MISSION COMMENTARY TRANSCRIPT Tape J,k 

Page 1 

This is Gemini Control Houston, 28 hours 3^ minutes into the mission. 
We are now entering the 19th circuit around the earth. The Gemini k space- 
craft lost signal - Igst contact with the Bermuda station at l:hQ Central 
standard time, just 5 minutes ago. This was one of the quietest passes 
across the United States. It started with a medical exercise involving 

Jim McDivitt at the Guaymas station. This, of course, requires exercise because 

apparently, 

it involves an oral temperature, / Ed White is about to drop off to sleep. We 

have indications he has been getting set to go to sleep for much of the last 
orbit, perhaps dozing a bit the surgeon advises. 

In the course of the pass, Gus Grissom talked to Jim McDivitt and asked 
Jim to look at his hatch mechanism on the right side and Jim did, reported 
on the position of the various handles and springs involved in that hatch 
mechanism, and we are completely satisfied that it is properly seated and 
there's no concern there. They have noted a slight rise in the oxygen sotirce 
pressure the last orbit or two. We were reading a source pressure of about 
950 pounds. We asked Gemini k to release a little bit of pressure. The 
automatic valve releases it if it builds up to a 1000 pounds, but we would 
just as soon manually release the pressure rather than to ask the automatic 
valve to perform that task. This apparently was done. 

Jim McDivitt, in the course of the pass, was preparing to eat a meal. 
He advised that he had drunk some water previous to the stateside pass, and 
he planned to drink some more with the meal. 

We also tested out, in the course of the pass, an airplane relay. .We 
were talking to the Gemini k spacecraft through an aircraft somewhere in 
the Kennedy area. The relay worked effectively, a noisy relay but a readable 
relay.

We are prepared to play the tape from most of that pass over the states 
for you at this time. 

S/C Flight, This is Gemini h 

FLIGHT Roger, Say, Jim, when you get a chance, will you check those 

two palls of the hatch handle and see if they are still free, or 
see if they are free or if they are locked in their position. 
We are just trying to run down the hatch problem down, here and 
we want to see if those things are still floating free. 

S/C You want me to turn them to lock and then unlock or something 
like that. 

FLIGHT Right. See if the spring is holding them in the lock position. 

Now, before you do it make sure that handle is stowed up good and 
tight. 

S/C Roger. We can keep it better ncv, but that doesn't say that the 

other thing will go around. 
FLIGHT Well, is the spring holding them in their position. That is what 

we want to know. Is the spring letting it float freely. 
S/C Yeah, the spring is leading itself ri^t now. 
FLIGHT The spring is restraining the valve, 
s/c ...

This is Gemini Control. We are now 29 hours and 14 minutes 
into our mission. Spacecraft Gemini 4 is now on its 19th 
revolution over the earth and currently is on the night side 
passing over the Indian Ocean about to come up along the coast 
of Australia. The White Team of flight controllers has taken 
over the second shift here in the Mission Control Center. 
Flight Director Gene Kranz is making a status check of all 
systems. The spacecraft electrical supply is excellent. We 
still have the same pad, or margin, available that we had at 
lift-off. There is plenty aboard to complete the mission. 
Communications are good. There's more than enough oxygen 
and more than one-half the OAMS fuel load still aboard. The 
Flight Surgeon reports the crew is in top condition as they 
continue this flight. This is Gemini Control. 



Mission Commentary Transcript Tape 36, Page 1 

This is Gemini Control. Spacecraft Gemini 4 is now 
29 hours and 40 minutes into the mission. The White Team 
of Flight Controllers has assumed control of this flight. 
The spacecraft is passing over the Pacific Ocean near Hawaii. 
As Mission Director Chris Kraft left the Mission Control 
room a few moments ago, he observed, "I don't see anything at 
this moment to keep us from going four days, and we will 
probably do an OAMS reentry." Spacecraft Commander Jim 
McDivitt reported to the Carnarvan tracking station as he 
passed over Australia, that Pilot Ed White is sleeping at 
this time. Earlier, Ed White reported to the Houston Mission 
Control Center that there was no sign of moisture build-up 
in the cabin of Gemini 4. Moisture build-up had been evidenced 
in previous flights. Gemini 4's cabin has been coated with 
a special cellulose cloth. This is Gemini Control.

This is Gemini Control. We are now 5O hours and 9 minutes into 
the mission. Spacecraft Gemini h has Just completed a pass over the 
States on its 20th revolution. In voice communication with Gus Grissom, 
spacecraft communicator, Command Pilot, Jim McDivitt, reported he had 
sighted another object in space. He described it only as an object that 
appeared to have big arms sticking out. He said he took some motion 
pictures of this object, but was having some difficulty because of the 
position of the sun. Dtiring this pass over the States, Gus Grissom gave 
McDivitt some updated times to perform various experiments. This is 
Gemini Control. 



Mission Commentary Transcript Tape 38, Page 1 

This is Gemini Control. We are now 3 0 hours and 31 
minutes into our flight. The Gemini 4 spacecraft is in its 
20th revolution and is into the dark side of the world as it 
passes over the South African continent. As relayed during 
our last transmission, approximately one half hour ago, the 
spacecraft commander, Jim McDivitt, had reported sighting an 
object in space. He said it appeared to have big arms sticking 
out, perhaps another - or a satellite. He said he had taken 
some motion pictures of this object, but the sun's position 
made it difficult to keep the object in view. We have had 
no further voice communication with the spacecraft since that 
time. But now we will play back for you the tape recording 
made during that pss over the States. This is Gemini Control.

This is Gemini Control. Spacecraft Gemini 4 is now coming 
up over Hawaii, and that tracking station will give the space- 
craft a Go-no-go for 33 orbits. Transmission difficulties 
made it impossible to do this over the Coastal Sentry Quebec,

copy? 

S/C Roger. Understand they want us to take areas of terrain 
wherever it is amenable and not to wait till the last pass. 
Be advised it looks we ought to save some film, though, until 
we get the opportunity to make a pass across the southwestern 
United States tomorrow and make a bunch of sequence photos there 
if it's ok.

This is Gemini Control. Spacecraft Gemini 4 is nov? passing 
over South America on its 21st revolution. There was no voice 
transmission over the United States. As the spacecraft came 
over Guaymas, spacecraft commander Jim McDivitt was advised to 
look for a tropical storm located west of Mexico. We have had 
no report from him on that. Here at Mission Control Center at 
Houston, we are checking with SPADETS here - Space Detection 
and Tracking System - concerning the object that McDivitt 
reported he saw on his last pass over the United States. They 
will advise us concerning the known satellites that were in 
that area at that time. One of these would be the Pegasus V. 
This is Gemini Control.

This is Gemini Control. We are now 32 hours and 10 minutes 
into our mission. Spacecraft Gemini 4 is now on the night side 
of the world passing over the southernmost tip of Africa on its 
21st revolution. Flight Surgeon Dr. Duane Catterson reports 
both men are in excellent physical condition. He said that, 
as of this morning's report, spacecraft commander McDivitt had 
taken throughout the flight a little under quarts of water and 
has eaten two of his complete meals. He said this represents 
about one half of the normal ground food intake. Pilot White 
has had a little less than a quart of water but has eaten a 
little more food than McDivitt. This report was, again, as of 
this morning. We have had no additional communication concerning 
food and water from the pilots, since the White Team came on 
duty approximately three hours ago. This is Gemini Control.

This is Gemini Control. Spacecraft Gemini k is now 52 hours and 
ho minutes into its mission. At the present time it is coming up on 
the Coastal Sentry Quebec, our tracking ship in the Pacific. During 
the last pass we had communications difficulties between the CSQ and 
the spacecraft. This was due to a power failure on the Coastal Sentry- 
Quebec. It was quickly corrected; however, the spacecraft had already 
passed out of tracking range and the system will be checked out with 
the spacecraft as it passes over in the next few minutes. We have 
had no other voice contact with Gemini h since Guaymas. This is 
Gemini Control.

present is approa^ching the Rose Knot Victor, a tracking ship located 
at the Pacific Ocean, west of Peru. Spacecraft Commander, James 
McDivitt, is in a sleep period. Our flight plan calls for Pilot 
Ed White to be working at this time on various experiments. He is 
to turn off MSG 1, an examination of the electronic charge buildup 
outside the spacecraft, using a sensor. He will also conduct a D-8 
experiment. This is measuring radiation inside the spacecraft, using 
a portable sensor. We have had no ground communication with the 
spacecraft with the exception of some updating of possible landing 
area data values for the past three quarters of an hour. This is 
Gemini Control.

of the African continent on its 22nd revolution around the earth. Com- 
munications between the ground and the spacecraft have been kept at an 
absolute minimum for the past half hour. This is directed by our Flight 
Director, Gene Kranz, in an effort to give Command Pilot, Jim McDivitt, 
a good sleep period. While McDivitt is in a sleep period. Pilot White

and will shortly pass by Midway Island on its 22nd revolution. Astro- 
nauts Jim McDivitt and Ed White will thus shortly set a new American 
record for long-duration space flight since Astronaut Gordon Cooper 
splashed down approximately 275 miles northeast of Midway in his 
Mercury spacecraft on May l6, 1965? after a flight of 5^ hours, 19 min-

just coming up on the coast of South America. During the pass over 
the Rose Knot Victor, a tracking ship off the west coast of South America, 
Spacecraft Commander, Jim McDivitt was in a sleep period. The Rose 
Knot Victor flight surgon asked Pilot Ed VThite for a medical pass Type 1. 
This included an oral temperature reading, a blood pressure check, a 
30-second exercise period with the bungie cord exerciser, and this was 
followed by another blood pressure check. White also reported he had 
k hours of good sound sleep. He has eaten a full meal and had about 
6 swallows of water. The meal consisted of beef bites, potato salad, 
fruit cake, and orange juice. After analyzing the data from the medical

present is over the mid -Pacific on its 2iith revolution around the 
earth. It is in drifting flight. We have had no voice communication 
with the flight crew now for more than 90 minutes by design. Space- 
craft Commander Jim McDivitt is still asleep from all indications we 
get on the ground and Pilot Ed White is busy performing various exper-

proceeding normally. Here at the Mission Control Center in Houston, 
our retro controller, Tom Carter, estimates that the second stage of 
the Titan launch vehicle, which went into orbit with Gemini U, will 
reenter about noon tomorrow, central standard time. Its impact point 
is predicted for 11° North latitude and 175° East longitude. This is 
near the Marshall Islands in the Pacific. In the 25rd revolution

sleeping, the medical data check on him was postponed until a later 
pass. The Type 1 checks are run once daily on the Command Pilot and 
once or more per day on the Pilot. The checks involve measurements 
of oral temperature, blood pressure, plus exercise on the bungle 
exercise device once per second for 50 seconds. The RKV Cap Com reported 
to the Flight Director that the spacecraft looked good on his telemetry 
readouts. A tape of this pass follows. This is Gemini Control.

S/C: Gemini 4, go ahead. 

CC: . Roger, read you loud and clear. Can you give me a 
little info on how your control went over North Africa and 
how much pul did you do? 

S/C: Roger, control in about the middle of the target 

of number 12 when by I had the period of 

pretty well squared away I could see the 

target, I believe. Target number 13 did work and 
clear, I was able to pick up the City of Alexandria, an airport 
and I think perhpas I have been able put my attention 

airport, I went ahead and operated the camera and took 
come pictures and I passed over the location on target from 
the data called up was it exactly.

Roger, understand. I have completed the second meal and had 



Tape 69, page 2 



approximately 6 swollows of water. I also had a good use 
of the defecation pack. And everything is in good shape. 

Flight Gemini IV, Houston Cap Com. Put your quantity read switch 
on and leave it on until I tell you, over. 

S/C Roger, it's on now. 

Flight Roger, I have some flight plan updates. Are you ready to 
copy? Gemini IV, Houston Cap Com, are you ready to copy 
flight plan update, over. 

S/C . . 

S/C Okay Houston, Go ahead, Gemini IV. 

Flight Roger. At GET of hj plus 00 delete. Translation 2 alpha.

about 47 hours you want translation 2 alpha, horizon scan, 
plume set check and horizon scan thruster plume check and 
insert D-9, run 1 at lU:li+:00 with OAMS. 

Flight Check, that is affirmative, Gemini IV. Also concerning 

Experiment MSG 1, we would like you to turn your ACK beacon 
off for a period of about 5 minutes during the period of 
your MSG 1 experiment. Recommend you do this between Conno 
and Carnarvon, this pass, over. 



Tape 69, page 3 



S/C I understand you want MSG 1 Experiment — the beacon turned 

off for 5 minutes. 
Flight That^s affirmative, Gemini IV. They want about 5 minutes 

of this experiment with your ACK beacon off when there are 

no UHF 'Cransmissions. 
S/C Roger, you want me to go to real time, delayed time, or you 

want me to turn the ACK beacon off at the circuit breaker. 
Flight Roger, use the circuit breaker. 
S/C Okay. 

Flight Gemini TV, Houston. We would like a repeat on yovr food and 
water report. 

S/C From the pilot, or do you want a new one from me. 

Flight That's from the pilot, please. 

S/C Roger, this is the pilot. I had, about 5 hours ago I had 

meal 2, day 2. I had about k l/2 swollows of water, I had 
a successful use of the defecation bag.

Had a good night's sleep? 

Wo, I got a little more sleep this time though, than I 
have been in the past. 

How about that plug in your throat there. Have you taken 
that out when you were sleeping? 

No, No, negative. No I didn't disconnect radio. I left 
it on. 

Did it bother you at all. 

Has been up till now but this time I guess I was pretty 
tired and I slept without it. 
Very good. 

Gemini IV, Houston. You can turn yo\ir quantity read switch 
off now. 

Gemini IV, Houston Cap Com. You can turn your quantity read 
switch off. 
Roger, it's off. 

Roger, you are looking good here. Have a good day. 
Which we will play at this time. This is Gemini Control. 
Gemini IV, Canary Cap Com. 
Go ahead Canary, Gemini IV. 

Roger. Request that you use the cabin repress valve instead 



Tape 69, page 5 

of high rate. Also "be advised that Houston says do not 
relieve through the cabin if you can avoid it. 
S/C We don't have any other place to put the oxygen except in 

the cabin. 

CC Roger. They are wanting you to avoid relieving through 

the cabin relief. 
S/C ©2 pressure dovm to 9 hundred and 10. 

CC Roger, I understand. 9 10. 

S/C Could youtell me why that they want to use the repress 

instead of the 0^ high rate. Where else are we to put 
the oxygen. 

CC Roger. 

Flight Canaries, this is Houston. 
CC Roger, Houston, go ahead. 

Flight We were using the repress because the 0^ high rate switches 
off the fan and tends to be noisy. Wanted to do this to 
keep the noise down in the cabin when one pilot was asleep. 
As far as the relieving — we were talking about relieving 
Overboard. Don't — ask him not to not to let the cabin 
jgyessure get so high that he actually relieves 0^ overboard. 
Normal system. You can point out to him that his 0^ use in 
the last couple of hours is about 25 percent up over the 
average for the day. 

CC Roger. Gemini IV, Canary Cap Com. 




Tape 69 page 6 

S/C Go ahead. 

CC Roger. The reason for using the repress is to avoid turning 

off your fans and to cut down on your noise level in the cabin. 
S/C Okay. 

CC Do not relieve overboard, if you can avoid it. 

S/C Okay Canary they don't want me to vent the ECS 0^ overboard. 

Roger, they want to vent it overboard through the cabin. Is 
that it? 

CC They don't want to avoid overboard at all if' possible. 

S/C Roger. I know it. 

CC Okay. Your 0^ usage for the last 2k hours, correction — 

Flight Canary Cap Com. Was that 2k hours? 
Flight Negative. Over the last 2 or 3 hours. 

CC Over the last 2 or 5 hours has been 25 percent higher than 

normal. 

S/C Roger. Our cabin has been holding alright. There really 

isn't too much we can do about that. That tank pressure goes 
up and that is Just about all there is to it. We are actually 
venting oxygen overboard that we don't need to. 

CC Roger 

S/C How is 0^ consumption. I have been plotting it and it 

looks like we are in reasonably good shape. 
Flight That's affirmative Canary. 

CC Flight, Canary. Do you have time on his Op? 



Tape 69, page 7 
Roger. He is in real good shape. He's got oh somewhere 
be-^een 5 and 10 hours above what we need. Plus the secondary. 

V 

Five or 10 hours above necessary plus secondary. 

Even at the rate he is using it right now. 

Your rate, even at your present rate, you will have enough - 

for 5 or 10 hours more than you need plus secondary Og. 

Okay, fine. Ihank you. ^ Planning to take your advice about 

not venting any overboard but I just don't know how I'm going 

to do that.

Controllers here in the Control Center and this is settling 
down to becoming a fairly routine practice now. It consists 
to an half an hour to 45 minutes of discussion between the 
oncoming shift and the outgoing shift member, conducted in- 
formally. We purposely try to schedule the shift change at 
a period when there is very little activity, no station 
contact; so that the full discussion can cover the previous 
eight hours. A word or two should be said on the operation 
of the Mission Control Center here throughout this flight. 
It's been nothing short of outstanding. We've had no problems 
in our very con5)lex communications system. Our computers have 
performed just an outstanding, uh, in an outstanding way. 
Here on the floor in the Control Cent'=»r we've been,.... the 
only small problem we have had has occurred in the last hour 
or two. A transformer in one of the consoles got a little hot

Australia. It will be another five minutes before it starts 
swinging across Mexico on a pass that will carry it across 
the Gulf and Florida. Uhhhh, the, in the next hour the pilot 
plans to perform some terrain and weather photography over 
the United States. Uh, all in all, we're looking fine here,

Hiis is Gemini control, Houston, in the 51st rev of the spacecraft 
over the Australian Continent. In the past hour we have had a report 
from Tannarive that they have been pleged by power failures out there, 
which has reduced their capabily on the teletype contact with this 
station. They plan to vertually shut down the station for the 
next 3 to h hours and expect to be back up with us around noon our 
time. In the last stateside pass we had planned to do some D-9 
experiments. Or in other words do some star sextion tracking. Ihis 
was not done however because the stars could not be seen in the 
daylight. The two are however performing star tracking experimentation 
right now over Australia. They've advised us because the are working 
with the sexton and controlling the attitude of the spacecraft there 
will be very little conversation during this pass across Australia. 
In the most recent pass across the states command pilot Jim McDivitt 
in a discussion with the fli^t surgeon noted some dryness in the 
throat which is expected from the oxygen atmosphere in the cabin. But, 
of - another medical sidelight of some interest to Dr. Berry however, 
was McDivitt 's statement that at the end of the first day or since 
the end of the first day some irritation around the eyes which is ex- 
pected from an oxygen invironment has cleared up. Gordon Cooper noted 
the same sort of irritation in his day and a half flight. The medical 
people here are wondering what's been planned to find out a little more 
about this. Hiey would like to know what the position of the faceplate 

has been since the end of the first day. The thought being that that 
could bear on whether there's — on this clearing up of the irritation

We have just lost signal with Carnarvon in the last minute as the 
spacecraft swings up across the Pacific, in contact with Canton Island 
station in 3 or ^4- minutes. Meanwhile we have racked up the tape on 
the last United States pass. We are prepared to play it for you now. 
Flight Gemini TV, Houston Cap Com. 
S/C Go ahead Houston, Gemini IV. 

Flight Roger, You busy with D-9? 

S/c No. I think it just drew to a close. We just can't see the 

stars in the daylight and I can't carry out the daylight portion 
of it. We will wait until we get back to the night time and 
do a little more with that. 

Flight Roger. I want to talk to you a little bit about this 0^ high 
usage rate thing. 

S/C Okay. 

Fligiit We don't think it's any problem. We would like for you to 

put your quantity read switch on and leave it on for the next 
several hours so that we can get a feel for what's going on. 
We want to try to — even at the rate that it's been used the 
last several hours. It wont be any problem. We would like 
to find some way to control this thing so it won't be a 
nuisance to you, so you won't be bothered with it. This is 
the reason we want to take a look at it for some time. Don't 
like the idea of you having to relieve pressures or build up 
pressures every few minutes. You read me? 



r' 



Tape 73, page 3 

S/C Houston, CSemlni TV. I got the to leave 

the read switch on for awhile and then all the rest cut-off. 
Say again. 

Flight Okay. Jim, how do you read now? 

S/C For the next couple of hours - say after that. 

Flight Wait until we get Bermuda acquisition. I'll tell you there. 

S/c Okay. 

CC Go ahead Houston, 

Flight Roger. 

CC Bermuda 

Flight What I was saying is we want to get a hack on whats going on 
with that pressure buildup in the primary 0^ system. We want 
to try to find someway to control without you having to 

re relieve cabin presstires every few minutes or every few hours 

so this is the reason we want your quantity read switch on 
for the next several hours. 

S/C Okay. What did you say about my usage? 

Flight It is a little bit higher than it has been but nothing to 

worry about. You've got — you have plenty so don't be concerned 
about it. 

s/c Okay. In plotting it, it looks like we are going to end up 

with 7 or 8 percent, maybe. 
Flight Yeah, we are just trying to find someway to keep you from 

having to relieve the cab pressure every new and then. 
S/C Okay. I don't like that either. 



Tape 75, page k 

Flight Say ah — the flight surgeon would like to know if either one 
of you have had any trouble with drying around the eyes or 
dry throat. 

S/C My throat is a little dry. And o\xr eyes were burning us by 

the end of the first day, but that's all cleared up now.

for you on the^ fuel, the onboard OMS ' s fuel. We still have 
195 pounds remaining as compared to 350 pounds at liftoff. 
In the last 24 hours we've used virtually no fuel although 
there has been some attitude adjustment here and there 
to snap a picture. Our systems people advise hov/ever there's 
been no measurable decrease. In the oxygen department we 
have 27*5 pounds of oxygen remaining in our primary tank, 
this compares with 50 pounds at liftoff, 24 hours to go 
we reported our remainder was 35 pounds and this would indicate 
a usage of something on the order of 7 to 8 pounds in the 
past 24 hours which follows very carefully, very closely, 
the expected plot. In addition to our primary oxygen tank, 
we have a two back-up, uh, secondary oxygen tank, each 
containing enough oxygen to keep a man in spacecraft com- 
fortable for a period of about one day. [^From. the North 
American Air Defense Command we're advised that Space Object

bring it all the way down to about 800 psi and that way, 
we can't find much else we can do about the thing, just bring 
it down lower so you work with a wider band, and we don't 
think this is going to use any more. 

S/C: if not 

I'll bring it down to around 800.

CC: Okay, that makes sense 

This is Gemini Control, Houston. We had loss of signal 
at Bemuda at 49 hours and 7 minutes into the mission. In 
the course of that pass we heard McDivitt discussing with 
Capsule Communicator Gus Grissom here that he felt the need 
for additional exercise. The flight surgeon urged him to 
go ahead and get the additional exercise and to advise us 
when and the duration of the exercise. In the course of that 
pass at 48 hours and 55 minutes, to be exact, we reached 
the mid-point in this flight of Gemini 4. That would have 
been some 13 minutes ago. This is Gemini Control.

This is Gemini control, ^9 hours minutes into the mission. Space- 
craft coming up^on the Carnarvon station. It is now about I5OO miles 
west of Australia. It has been a very quite pass since the space- 
craft left the United States. Very little contact across Africa. 
We've been in active conversation vith various offices at the Goddard 
Space Flight Center and at the North American Defense Command regarding 
this sighting of a satellite yesterday. We are fairly well convenced 
now that in all probabilty this was Pegasus. The clues would depend 
largely on the angle at which the Gemini IV spacecraft approached 
Pegasus. Earlier we had indicated Pagasus some 1000 to 1200 miles 
away. However, the angle and the speeds of the bodies would make those 
closing distances very significant and the concensls is right now that 
it probably was Pegasus that Jim McDlvltt saw. He advised us this 
morning that he would guess that it was somewhere between 10 to 20 miles 
from him. They still don't know precisely which direction he was viewing 
it from. At k9 hours, kj minutes into the mission. This is Gemini control.

48 hours of the mission. In the food department the first 
24 hours of the flight Jim McDivitt ate two meals for a 
total of 904 calories. For the second 24 hours of the flight, 
McDivitt also ate two meals and the total calorie intake was 
1,222. Meanwhile Ed White on the first day, also had two 
meals. His total calorie intake was 1,187 calories. On 
the second 24 hours Ed White had 3 meals for a total calorie 
intake of 1,868 calories. The pilot, the command pilot, Jim 
McDivitt, during the first ?4 hours of the mission drank

into the mission to 34 hours and 21 minutes into the mission. 
He went to sleep at 34 hours and 21 minutes into the mission 
and he slept until 37 hours and 20 minutes. He was then awake 
from 37 hours and 21 minutes until 42 hours and 36 minutes. 
There followed a sleep period of more than 3 hours from 42 
hours and 36 minutes into the mission, until 45 hours and 48 
minutes into the mission, and this was described by McDivitt 
as the most restful sleep he has had, so far in the mission. 
He woke up at 45 hours and 48 minutes into the mission and 
he's still awake. For Ed White during the past 24 hours, he 
was awake from 25 hours and 45 minutes until 29 hours and 15 
minutes. He went to sleep at that point and slept until 33 
hours and 15 minutes into the mission. He was then awake

Defense Recovery Forces here in our recovery center, that the 
second stage of the Gemini launch vehicle which put Gemini IV space- 
craft in orbit is at this precise time reentering. It is burning 
up into the atmosphere over the Atlantic Ocean. The radars at 
Cape Kennedy are tracking it and very shortly we hope to be able

This is Gemini control, Houston, 50 hours h6 minutes into the flight. 
Spacecraft is - about 5 to 5 minutes ago lost contact with the 
Bermuda station- after a state side pass. In the course of that 
pass the pilots talked to the communicator, Grissom, here about 
some medical matters, read out medical quantities. They also got 
into a discussion about the sleep rest cycle. Jim McDivitt reported 
that Ed White had been dozing for the past hour or so but apparently 
not sleeping too soundly. He pointed out that they weren't too tired, 
but that they were probably ought to take another look at their sleep 
cycle at some point during the next revolution. We are prepared to 
play that conversation for you now.

You can turn your computer off. 
S/C Okay, our computers are off. 

Flight Okay, and if you want to - in fact we would like for you 

to update all of yotir type 2 medical passes to type 1. That'll 
give you a little more exercise. 

S/C Okay, very good. All -ype 2's to type 1. 

Flight Okay, and how much has Ed been sleeping the last couple of 

hours. Can you give us a clue on that? 
S/C Roger. Ed's only got about an hour nap. We are going to 

have to rearrange our sleep cycle here a little bit too. 
Flight Okay. Have you felt rested with the amount of sleep you've 

got or do you think you need some more? 
S/C No. I don't think- we'll ever get an awful lot of rest out of 

it, but on the other hand we're not doing much. We're really 

not too tired. I think we'll go throu^ this next pass and 

then go back to sleep again. 
Flight Okay. The other thing is — when you were doing your maneuvering 

during the first orbit, did you get that recorded on your

At this time the spacecraft is over the Indian Ocean coming up 
on Carnarvan intercept. We have data from Goddard and from the 
Department of Defense indicating that the second stage of the 
Gemini launch vehicle reenetered the atmosphere at approximately 
11:30 a.m. Central Standard Time over the central Atlantic Ocean 
Our approximate coordinates on that point of reentry right now 
are about 33 degrees west by 15 degrees north. That was 33 
degrees west - 15 degrees north at 11:30 a.m. Central Standard

This is Gemini Control, Houston, 52 hours and 23 minutes 
into the mission. In the last 15 minutes here in the Control 
Center we broke in two new Capsule Communicators by the names 
of pat McDivitt and Pat White. Pat White opened an exchange 
with Pilot Ed White, who happens to be her husband, as the 
spacecraft came into contact with Guaymas about 20 minutes 
ago. The conversation was not the normal from husband and 
wife conversation. It was very businesslike. Ed was advised 
to turn switches here and there and he did so without changing 
the expression of his voice for some five or ten minutes. 
Apparently he knew who was broadcasting on the other end, because 
at one point he comes in and he - he came in and he said, that 
the Capsule Communicator here was a great improvement over Gus 
Grissom with whom he had been talking for about the past seven 
hours. Both pilots were advised to drink a lot more water - 
this was on the advice of the surgeon - during the coming 
revolutions. They were also advised that they should plan for 
a good long sleep period. They had been busy working with 
their experiments now some eight to ten hours and they are 
apparently in for a break from experiments for - oh, the next 
twelve to eighteen hours . The surgeon wants to see them get 
a good long restful sleep. During the United States pass

with Gemini 4 to check the onboard systems and, if all is 
normal, we'll give spacecraft commander Jim McDivitt a Go 
for 48 revolutions. Flight Director Eugene Kranz has advised 
the Coastal Sentry Quebec that everything here in the Mission 
Control Center at Houston is in a Go condition for the 48 
revolutions . This is Gemini Control .

This is" Gemini Control. We are now 55 hours and 40 
minutes into the mission. Spacecraft Gemini 4 is on its 36th 
revolution around the earth and is coming up on the west coast 
of Africa on the night side. Voice contact was made with the 
flight crew by the tracking ship. Coastal Sentry Quebec, and 
t^e Hawaiian tracking station in the Pacific, also by the 
Guaymas station, Mexico. At that time» spacecraft commander . 
Jim McDivitt reported his spacecraft was in a Go condition. 
After a systems check the tracking ship Coastal Sentry Quebec 
-gave "McDivitt a go for 48 revolutions . The Coastal Sentry 
Quebic also updated the spacecraft with times for various 
landing areas. Over Hawaii McDivitt reported that his space- 
craft companion, Pilot Ed White, is asleep and that the space- 
craft had been powered down. As a result. Flight Director 
Gene Kranz ordered that voice communications with the ground 
stations be held down to a minimum. Over Guaymas McDivitt 
advised he had his helmet off. The ground station updated his 
map and then broke off the contact. We will now play back 
the voice tapes as one unit made of the contacts with the 
Coastal Sentry Quebec and the Hawaiian and Guaymas, Mexico, 

tracking stations.

This is Gemini control. The Gemini IV spacecraft has Just passed 
over Vietnam. The ground elapsed time is 56 hours 8 minutes. 

And the spacecraft is on its 56th revolution of the earth. There has 
been no voice communication with the flight crew since our last tape 
relay from the Pacific area. Voice communication has been reduced 
so the flight crew can get a maximum of rest. Pilot Ed White is 
asleep. Spacecraft commander, Jim McDivitt, is preparing to do some 
photography according to our flight plan. At present the orbital data 
is approximately 175 statute miles apogee and 101 statute miles perigee. 
The spacecraft is powered down and is in drifting flight. Here in 
the mission control center activity is also in a low key. This is

the start of the Gemini IV fli^t. The spacecraft is on its 56 revolu- 
tion of the earth and is now over the Pacific Ocean between Hawaii and 
the United States. The spacecraft passes over the Coastal Sentry 
Quebec tracking station and over the Hawaiisin station were both 
passive. Ihe tracking stations confined their activity to telemetry 
reading of spacecraft and flight crew environmental systems, and in 
receiving of automatic telemetry data from the spacecraft. The 
Hawaii Flight Surgeon reported that Pilot Ed White is asleep and that 
spacecraft Commander Jim McDivit is very quite and possibly also 
asleep. Hawaii also reported that all the spacecrafts systems look 
very good from the ground. This is Gemini Control.

Hiis is Gemini Control. Spacecraft Gemini IV is now over the 
Pacific Ocean on its 57 revolution around the earth. At this time, 
our flight crew has spent 58 hours and 10 minutes in weightless 
flight, which is a greater amount of time than the total spent in 
space by all other American astronauts combined. That total was 
58 hours 9 minutes and 25 seconds achieved in the Project Mercury 
flights of Alan Shepherd, Gus Grissom, John Glenn, Scott Carpenter, 
Walter Schlrra, Gordon Cooper, and the Gemini HI flight made by 
Gus Grissom and John Young just a little over 2 months ago. And, 
as the spacecraft was passing Hawaii just a moment or two ago, 
we had our first voice contact with the flight crew in more than 
2 hours. Spacecraft Commander Jim McDivit sounded a little sleepy, 
but he did respond. He was advised that in about 15 minutes the 
Pegasus Satellite will be in the area of the spacecraft at a slant 
range of about ^00 nautical miles and we can assume that they will 
try to get a sighting. This is Gemini Control.

Since leaving the South American continent, its path on this 58th rev-

out of range for approximately 1? more minutes. When it will cross the 
tracking range of the Coastal Sentry Quebec, a ship located in the

This is Gemini Control. The Gemini spacecraft is now 59 
hours and 43 minutes into its flight. At the present time, 
it is over the Pacific Ocean on its revolution path that will 
take it down around the southern coast of South America — 
the southern tip of South America. During our last voice communi- 
cation with the spacecraft which took place over Hawaii, we 
noted that the spacecraft commander, James McDivitt, reported 
that he had seen another satellite. He gave us a time hack 
on this sighting and said it was at 02 hours and 38 minutes GMT. 
That would place the sighting at approximately 15 minutes before 
our voice transmission started with the Hawaiian Tracking Station. 
We have had no further contact with the spacecraft since that 
time, and the Spacecraft Commander James McDivitt did not 
elaborate further on his sighting. We expect that we may get some 
additional description from him at one of the later tracking 
passes, but at this time we have no additional word on it; and 
we will give you anything that we do get. At the present time 
when the spacecraft crosses the South American continent, it 
will be again on the night side of the world. This is Gemini

Just a few minutes ago, we had a remote voice conservation between 
Roger Chappe, our spacecraft communicator here in the Mission Control 
Center and Pilot Ed White. This was through the Kano Nigeria tracking 
station. Astronaut Chappe gave astronaut White a start time for 
another sextant navigation experiment. We will now play back this 
taped conservation.

CC: Okay, lets a problem 

S/C : Very Good 

S/C: Looks like I'm starting to iche a little.

S/C: I say I look like I'm starting to i|iche a little 
CC: I know what you mean. 
CC: Flight, Canarvon 
F: Go 

CC : Okay, he is looking real good, he's got his, uh, platform 
all powered up, it looks' like its lining up right, the computers 
on prelaunch and everything looks fine. 

F: Roger, wonder if you can get an estimate from him as to 
how long it took to warm up. 

CC: Allright. How long did it take you to warm up the platform? 
S/C: 4.5 minutes. I turned it on 11:50 - at 12:15 I got the

active arrow light which indicates it had warmed up. 
CC: Okay, 25 minutes, thank you. 

S/C: Roger, I didn't start lining it now until about 12:30 
after 

CC : Roger 

F: We have that, Canarvon 

S/C: command, I started with a pretty bad reference because 

I tried to get this MSG pack on. It took about 15 minutes, 

17, minutes to align properly. 
CC: Ah, roger, I understand. 
CC: Looks like your cohort woke up, huh? 
S/C: Yeah, I'm pretty busy here, he has to come along 
he only got time for about 15 minutes 

CC:. 

S/C: so I guess your 're having. too much 

trouble. 

CC : out 

CC: Flight, Canarvon 

F: Go ahead, Canarvon 

CC : I think that the next time you have a site where he is 
going a little OMS thrusting, I show OMS show right and OMS 
show left which is an impossibility. 



Mission Coitimentary Transcript Tape #119, page 3 

CC: I think the next time you come over a site with 
you can do the checking . 
F:] Roger

CC: Go ahead. 

S/C: I see some lights shining on the clouds down below me. 
CC: Alright, that should be Melbourne. 

S/C: Okay, tell them I thank them for lighting the night for me. 
CC: Oh, very good, they'll appreciate that. 

S/C: Tell them the next time they ought to get these clouds out 
of tte way so I can see the city and not just the clouds. 
CC: That's the same way I feel about this. 

CC: to yaw maneuver. to yawing, Gemini 

4? 

CC: Canarvon 
F: Roger, Canarvon, how 'bout giving us a run down on that? 
CC: Okay, he looks real good, he seems to be in a real good 
mood. Sounds a lot better than he did yesterday. His clocks 
look pretty good except for that same old lag in the FCT. 
Showing activity on the OMS and all thrusters just about. 
His horizon scanner seems to be working real well. We only 



Mission Coiranentary Transcript Tape #119, page 

had one horizon search during the past with small little time. 
F : Roger 

CC: And he, the AC volts are 25.7 and they stayed steady throughout 
the pass. He said his platform lined up real well. Took him between 
15 and 17 minutes to align it. 
T : Roger 

CC: And he thinks he saw some lights, I believe they might have 
been Adelaide, but he thinks they're Melbourne so we let it go 
at that. The one thing is like I just mentioned to you before. 
My OMS yaw right and my OMS yaw left bi-levels are coming on some- 
times exactly at the same time and if he makes a OMS maneuver or 

over another site, then tell me whether or not 
I've got a problem here. 

F: Roger, GNC has something here he wanted to say. 

GNC: Ah, Canarvon CapCom, just wanted to confirm that he wasn't 

rolling and that, I'm sure your systems man was probably watching 

that, so, uh, I'd like to confirm that wasn't roll control that 

you were seeing. 

CC: Hold on a second 

S/C: It was a roll control when we saw the search. 



Mission Commentary Transcript Tape #119, page 5 

GNC : What I was wondering, Harry, was that, uh, when, uh, you 
said that both of them firing at the same time, could that have 
been roll control because you know he's got to fire one left and 
one right . 

CC: I don't think so, they're both going off at exactly the 
same time. 

GNC: Okay, we'll take a look at it. 
CC: Okay

CC: Jim, this is Houston, your passes over Canarvon, uh, we 

have not been receiving data from Canarvon, uh, when you uh, 

go around the next two passes, particularly the second pass from 

now would you attempt to maintain a fairly zero zero attitude. 

S/C: Okay , Canarvon says he's been having an awful lot of rain, 

could that be part of it? 

CC: That could possibly be, they're had a tremendous amount of 
rain during the past few hours. 

S/C: What time am I going to get to the Canaries? 

CC: What time are you going to get to the Canaries, is that what 

you want? 

S/C: Yeah, I want to know whether I should start looking for my

CC: Roger, have you been pulling your head sets when you 
go to sleep? 

S/C: Yes we have, the last couple of times. 
CC: Roger, this helps a lot, right? 
S/C : Yes , it does . 

CC: Okeydoke, Jim, I'll be turning you over to the daylight 
crew. 

S/C: Okay, when are they going to promote you to the daylight 
crew? 

CC: I don't know, it sure would be nice to come to work at 
8 o'clock in the morning. 

S/C: Well, you can always go home and come back at 8. How 'bout 
that?

This is Gemini Control, 71 hours 14 minutes into the 
mission. And for the last three days we've started each 
message with the ground elapsed time .Of increasing significance 
today throughout the day will be another clock here in the Control 
Center one labeled QMTRC or Greenich Mean Time to retrocommand . 
That clock presently reads 22 hours and 4 minutes. We have 
just changed shifts here in the Control Center and we have a 
visitor, Chris Kraft's son. His name is Gordon, he is 13 years 
old and his dad is showing him around his console, how it works, 
and some of the many switches and many lights that he follows 
in the course of his 8 hour shift. We are in the 46th revolution 
with the spacecraft over the central Atlantic Ocean. We lost 
contact with the Bermuda station about 2 minutes ago. Canaries 
should acquire about one minute from now. This is Gemini Control.

This is Gemini Control. We are on the 46th revolution 
coming up on Canton Island. Mission Director Chris Kraft has 
decided that based on the present apogee and perigee no further 
adjustments will be necessary in the orbit of Gemini 4. We 
have no further maneuvers to adjust the lifttime. He's entirely 
satisfied with the lifetime which presently reads 99 miles perigee 
164 miles apogee, both in sfeatute miles. The crew will be advised 
of this decision on the pass coming across the United States in 
approximately 10 minutes. 

The weather around the globe looks like this this morning. 
In the western Atlantic it is part].y cloudy, winds of about 10 
knots, seas running 2 to 4 feet. This is also true of the eastern 
Atlantic. Generally, the Atlantic is calm. The mid-Pacific area, 
partly cloudy conditions, ceiling 15,000 feet, the winds running 
5 to 15 knots, seas 2 to 4 feet. The western Pacific, the weather 
has been consistently poor throuhgout this mission. It remains 
that way. Frequent showers in the area south of Japan of which 
our ships are congregated should that area become necessary as 
a landing area is exper icing frequent showers and they are expected 
to continue today. Overcast includes winds 15 to 20 knots and 
seas running 8 to 10 feet. This is Gemini Control.

This is Gemini Control, Houston, 72 hours 56 minutes into the flight. 
Our oxygen quantity at the present time is reading 21 pounds remaining in 
contrast with approximately 50 pounds at lift-off. This usage read is 
right on: the expected curve. In the electricity department, we have 
remaining 1,032 amp hours left In contrast with 2,200 amp hours at lift-off. 
This is about I50 amp hoiirs below the expected usage rate. In the CAMS 
fuel department, at lift-off we had 36Q pounds. We now have 175 pounds 
remaining. In the past hours we have used about I5 pounds , and 
throughout the course of this day we expect to use an additional to 
■pounds performing various maneuvers, yaw checks, and we expect to use the 
horizon scan mode a good deal today which is demanding in the fuel depart- 
ment. ..We will hold in reserve I3O pounds for our pre retro OAMS burn. 
The worldrange of stations is green in all respects. All equipment, is 
functioning properly. Jim McDivitt and M White have eaten in the past 
2k- hours the following: 

McDivitt has taken in 1,755 calories, pilot Ed White has taken 
1,950 calories. McDivitt has drunk I6OO cc of water, and the 
pilot has drunk approximately the same amount. 

McDivitt has slept in the past 2k hours about 5 hours, k-l/2 of which 
he described as soxind sleep and about I/2 hour of dozing. Ed White has 
slept 6-1/2 hours, about k of which were described as soxind and 2-l/2 as 
dozing. Jim McDivitt is awake now, and Ed White is dozing and attempting 
to get some additional sleep. In the pass across the United States, 
completed a few minutes ago, McDivitt and White were advised to run the

next - most of this day with the awake pilot with his helmet off and his 
gloves off. They were instructed for the sleeping pilot to leave his 
faceplate open and attempt to shade the window to keep the sun out of 
their eyes in order to sleep, McDivitt advised that they have heen doing 
very close to this for the past 12 hours. He said neither had taken his 
helmet off. However, he indicated they would attempt that. The idea 
behind this instruction is to get ein even closer — an even sterner test 
of the humidity factor in the cabin. We are very pleased with it here. 
The environmental officer is quite pleased with the performance to date. 
We are showing humidity reading consistently at about 60 percent. McDivitt 
advises that the cabin temperatxire has run a very steady 65 degrees. 
Over Guaymas, we completed a medical pass on McDivitt, took his blood 
pressure before the use of the exerciser and following,' got very good 
values there. We are prepared to play for you the tape conversation 
of the pass across the United States at this time.

CC Say again, Gemini 

S/C I had a lot of water, I don't know how many gulps, but after I 
had about 20 or 30 gulps along with a couple of meals in the 
last 2 hours — 

CC . Roger. I understand . . . Charley . 

S/C That's right, I haven't been to sleep for about 2 or J hours. 

Ed can sleep for about 5 or 6 so I probably won't go off again 
for 6 or 7. 

CC Roger. I understand. Thank you, and out

S/C Okay. Go ahead 

CC Okay. At 2l+ ft/sec forward, that's hO seconds, 120 ft/sec aft, 

that's 2+52, at 17 20 20, 2+55, &<-55. Then your h6-l time without 
bum, 17 1^ 57, 7-^1, 1^-29- 

S/C Got it. 

CC Okay, now I've got other information to pass up to you here. We 

would like for the pilot who is asleep to leave his faceplate open 
and his gloves off, and then we would like for the pilot who is 
awake to take off his helmet and. gloves and use a lightwei^t 
headset for communications, if he can. We would like for you to 
continue this way up until about 5 hours prior to retrofire. Then 
once in orbit, at your convenience, we would like for you to take 
a wet and dry bulb reading at any station and give us a report of 
what it was and what time you took it. 

S/C Okay. We have had the gloves off now for the last 12 hours, but 
mostly headset . . . when we are sleeping we generally put that 
viser cover oyer it to keep the sun out of our eyes. 

CC Roger. 

S/C The humidity is staying down around 60 percent. 

CC Roger. Okay, Jim, We have decided that you have got a little 
bit of fuel - got some fuel that we can play with here in the 
flight plan. So we would like for you to go to the horizon scan 
mode for the next 8 hours. Th&t 's until elapsed time of about 
80 50, and we want you to use the primary scanners. We don't want 



Mission Commentary Transcript Tape I27, Page 5 

you to do any controlling in yaw, and if the scanners break 
lock, don't control in roll or pitch either. We want to see if 
it breaks lock, we want to see if it will reacquire. 

S/C Okay. You want the horizon scanners in the next 8 hours. 

CC Affirmative 

S/C 80 hours elapsed time. 

CC Roger 

S/C Okay, Gus, for ... pressure, we haven't been able to do 

much with D burn, because we haven't been given the fuel for it. 
We want to save a little . . . for that. 

CC Okay. We got no problem. Go ahead and use your D-9. Now on the 
— got an Apollo landmark nmber 2, and we would like for you to 
be in attitude for that at I7 I9, G.ra. t. of I7 I9, and the target 
will be 16 miles north of track, and you should be pitchdown about 
-50 degrees at that time. We would like for you to track this 
as close as possible and get some pictures, using the I6 ram camera 
with the 75 mm lens with a nominal iens setting. 

S/C Okay will do. 

CC Okay, do you want me to repeat any of that? 

S/C Apollo number 2 at I7 I9, I6 miles north of track, pitch of 50 degrees 

and use 75 ™i lens, and then — 
CC Roger, and really have at It and track it close, use your reticle 
S/C Okay 



Mission Commentary Transcript Tape 127, Page 6 

CC Okay. Your orbit . . . runs 9 and 10, do as scheduled in the 
flight plan. Do it just as you previously planned to do it. 
Just for information, 9 is scheduled at an elapsed to 75 3O, 10 at 
75 50. 

S/C Okay, we vill go to the orbit . . runs 9 and 10 as scheduled to 
75 50 and 75 50. 

CC Roger. Okay, we are going to come up with some more tracking 
tasks for you, I think, and we want most of this to be done 
pretty tight. 

S/C Okay. Very good. 

CC Okay. I've got a map update for you if you want it now. 
S/C Okay. Go ahead. 

CC Okay. I70 degrees east at a G.m.t. of I7 00 00. That's rev 47. 
S/C Okay. 170 degrees at 17 00 00 rev k7, 

CC Roger. You can bring your quantity readoff . You can bring ■ 

your computer off also. 

Go to Bermuda on the ground 
CC Gemini IV, Houston, how do you read now? 
S/C Loud and clear. 

CC Okay, did you get the quantity readoff and computer off. 
S/C I'll get them now. 

CC Okay. Fll^t would like to know if you are going to try sleeping 
with your helmet off. Try sleeping with yotir faceplate open, I'm 
sorry. 



Mission Commentary Transcript 



Tape 127, Page 7 



S/c I don't know. The sun really gets in your eyes. I don't think 

we will try that. Ed just tried sleeping with helmet up and then 
down — right now he just tumped it up. He is having a tough time 
with the helmet. I tried it and I can't do it. 

cc Okay, can you put the shade over it anyway? 

S/C Yeah, you can sleep with it just about half open. How about 
that? 

CC Okay. 

S/c Actually, the last 2 hours or more, maybe it is as much as 2k, 
we haven't been too careful about keeping our faceplates closed 
and our wristbands off, because obviously the humidity is going 
up. 

CC Yeah, of course, that's what we are trying to do, we are trying 

to get a good hack on what is happening there and see — maybe we 

don't have a problem like we originally thought. 
S/C I don't think we do. Especially, Ed hasn't had his faceplate 

closed in the last 12 hours, and I only had mine closed when I 

was sleeping. 

CC Okay. Go ahead and do what we asked there as soon as you can and 
give us those wet and dry bulbs so we can get a good plot on this 
thing. 

S/C Okay. I have been worried . . . and the temperatures have been 

running — the dry bulb are running between 72 and 75, and the wet 
bulb between 60 and 6k. So the relative humidity is staying pretty 



Mission Commentary Transcript 



Tape 127, Page 8 



close to around 60 percent. . . - 

CC • Very good. . ;" , 

S/c There is no difficult moisture. There. isn't any moisture on that 

. . . paper, and unfortunately . ... clutter .up the wall and I can't 

take the temperature, but the most temperature I can fight is about 

65.

This is Gemini Control on the 47th revolution around the 
earth with the spacecraft northeast of Australia. In the recent 
Canarvon pass we got what Dr. Berry described as some of the best 
medical data he's seen yet. He is extremely pleased with the 
quality of the telemetry and with the values he saw. As we 
crossed the Pacific Ocean the Canton Island station should be 
in contact, Hawdi should have a good contact on the order of 3 
to 4 minutes and then as we cross the United States the pilots 
plan to perform an Apollo landmark investigation check. From 
the Cape they will receive an update, a computer update for the 
values necessary before a 51-4 landing, if that should become ^ 
necessary between now and the 51st revolution. We are prepared 
to play for you at this time the conversation between Gemini 4 
and the Canarvon Station. 

CC: Gemini 4, Canarvon capcom. You look good here on the 

ground, we are standing by if you have any thing you need. 

S/C : Roger, Capcom, Gemini 4 on

F. Canarvon, what attitude mode do you show on the ground? 

CC: Horizon scanner, primary 

F : Right 

CC: Thank you. 

CC: It has stopped raining, a little bit wet, tho . 

S/C: Very good. We sure wild farms in the last 

couple of days. 

CC: about 3 inches of rain today, the people around 

here can really use it for the sheep, it's a low time of the year. 

S/C: Ah, right. Kangeroo but I can't through the 

CC: Your buddy awake. 

S/C: No he's sound asleep 

CC: Flight, we're not getting too much radar data. 

F: Understand. 

CC: This problem, I believe, is internal to this station. 

F : Roi^er 

CC: Flight, those horizon scanners seem to be looking real well 

Just getting a teeny bit of drift on the roll but no at all. 

The pitch is holding real tight and the, but, uh, just a teeny 

bit of roll but very, very little.

extra fuel to play with so we're in the process now of working 
in some other tracking tests, some other things into your flight 
plan and we'll be passing up to you as you go along. So we're 
going to do a little more controlling.

CC: Your orbit right now is 86.3 by 141.6. Staying up very 
very well . 

S/C:] Very well. 

CC: Did you do a main battery check on the last orbit? 

S/C: I'll do it, do you want it 

right now? 

CC: Well, can you do it? We can wait a little while until 
Ed wakes up, if you want. 

S/C : Nah, he? 11 be asleep for a while, I'll try to do it.

Canaries . 

S/C: You don't go over the Canaries this pass? 

CC: Nah, but you can do it between now and Canarvon 

S/C: Okay 

CC; Okay, here's Haney's news release. It says in the 
morning paper that you're not going to go for 5 days. This 
came up in a press conference last night and in answer to the 
questions Chris said it looked like we had the consumables to 
make it but we had no plans to do so.

hours from now, we should have retro fire. We are in our 48th 
revolution with the spacecraft on the crossing the seventh, the, 
uh, southern tip of Africa coming up on a night time period in 
a very few minutes. We've been out of touch since loss of signal 
at Bermuda. Perhaps 15 minutes agon. During the next hour the 
spacecraft will perform some orbital navigation checks between 
Hawaii and Guaymas. It has been running in the horizon scan 
control mode now, for the, uh, past two hours. It uh, will continue 
that mode for, throughout most of the day. All in all we're looking 
fine and dandy here in the Control Center, we have another visitor

Gemini Control here 75 hours 10 minutes into the mission of the 
U8th revolution with the spacecraft northeast of Australia. Gemini IV 
got its updates on future planned landing areas, contingency landing 
areas in the pass over Carnarvon, and there was no other business to 
take up at that time. They are still flying in the horizon scan control 
mode. We here in the Control Center , the controllers have taken a 
luncheon break. In the course of taking mine, I chatted with the gentle- 
man from a local catering firm that has handled our cafeteria about 
2 steps off the Control Room floor. His food certainly Is worthy of 
mention. He has provided around-the-clock cafeteria service since lift-off. 
You get a nice luncheon spread, sandwich, etc. for about 95 cents. 
Sausage, eggs and coffee for about 50 cents. He tells me since lift-off 
he has served more than 2800 cups of coffee. I couldn't resist asking 
what the planned usage rate was, and he said, "like everything else in the 
mission, that's just about as expected." This is Gemini Control.

This is Gemini Control Houston, 75 hours 58 minutes into the flight. 
Within the last minute, we acquired the Gemini IV spacecraft by the 
Guaymas station. We are reading solid TM now on the ground from Guaymas, 
and momentarily we expect Gus Grissom and Jim McDivitt to get into 
conversation. Texas has acquisition. Stand by and let's tune in live

This is Gemini Control, Houston, 76 hours 11 minutes into 
the mission. We're in the 49th revolution. In the last pass 
across the United States toward the end of that pass, comparing 
notes with the ground, Jim McDivitt noted some trouble in his 
on/off switch in operating the computer. The indications are 
that the switch may have been stuck in the ON position. There 
are several ways around this switch, the most important of which 
is the Master IGS power switch. McDivitt was advised to turn 
the IGS power switch off and leave the computer in the ON 
position. We're unable to confirm whether he received that 
transmission as it occurred toward the 'jfag end of his U.S. 
pass. We will confirm it at subsequent stations, however. 
We're ready to play for you at this time the tape of the pass. 
The conversation begins approximately at Texas. There was no 
conversation during the first half of pass. Let's have the 
tape. 

CC Gemini 4, Guaymas Cap Com. 
S/C Go ahead, Guaymas. Gemini 4. 

CC Roger. All systems are green. We've got a change in time 
for your D-9 experiment, run 4. 
S/C ok. Stand by one.

S/C @0 51 Zulu? 

CC That's affirmative. Flight, Guaymas Cap Com. 
Flight: Go ahead. 

CC All systems are green. We passed up that information. 
Flight: Roger. 

CC That TR clock looks like about one second leading.

CC Jim, would you turn your computer on. 

S/C Roger. 

CC Ok. I've got another experiment to pass up to you here. 

S/C Ok. Just a minute. 

S/C Go ahead, Houston. Gemini 4. 

CC Hey, Ed, you're awake, 
S/C Hi . 

CC This concerns the zodiacal experiment which is going to be 
on 5. And they want to find out if they're going to get any 
fogging of their film from the attitude control thrusters . So 



Mission Commentary Transcript Tape 133, page 3 

we'll likely use your 35inm Conterax and you can use either 
black and white film or color. And set it wide open at F18 
with the range set at 8 feet. Then we'd like for you to put 
the camera against the window and hold it so that the nose 
isn't in the field of view. Then we'd like two sets of photo- 
graphs. One should be in pulse mode and have the spacecraft 
pointed straight down to black earth - this will be - I'll 
give you a time to start it - this will be at the black earth 
on night side and then give one pulse up pitch - pitch pulse 
up - and get a picture with the shutters of the camera open 
in a bulb position. And as you come up through the horizon, 
why, get another picture with pitch-down pulse with another 
frame of the camera and again let the shutter wide open at that 
time. And then we want the same type of picture - we want a 
picture pulse up with the horizon view, with the black earth 
view and a picture pulse down with the horizon view and the 
black earth view. 

S/C Roger - I got a pulse up and pulse down with the bulb 

position on the 35 mm black and white or color. Set it up in 

18 at 8 feet. 

CC That's affirmative. 

S/C Ok. Will do. 



Mission Commentary Transcript Tape 133, Page 4 

CC Ok. We recoiranend you do it on rev 51, starting at about 
21 40 GMT. 

S/C Roger. Rev 51, about 21 40. 

CC Roger. You can turn your computer off now. We checked 
your load in it and it's all ok. 

S/C I have a question on the D-9 experiment. Is that the Apollo 
run Number 4 or is that the other - the Air Force run Number 4? 

CC It's Air Force run. 
S/C Ok. When are we going to do the Apollo run 4? That's the 
one where we take all those — 
CC Didn't you do it? 
S/C . . . 

CC Didn't you do it? Didn't you do the Apollo one? 
S/C No. We haven't done that one yet. 
CC Ok. We'll schedule that for you. 
S/C Ok . 

CC Ok. Jim, would you press on your sternal leads? Hey, and 
we have indication that you're using about two amps more that 
we think you should. We're wondering what is the position of 
your suit pan, or do you have something else on that we don't know 
about . 

S/C Yeah, we have the suit pan at two - we'll turn them back to 
one. 



Mission Commentary Transcript Tape 133, Page 5 

CC Tha t ' s ok . 

S/C Hey, I just - I still have my malfunction light and my 
computer light on with the switch off. 

CC We show, a computer on and no malfunction light. What's 

your status now? With the computer? 

S/C . . . prelaunch and some other mode. 

CC What mode were you in when you got your malfunction light? 
S/C What? 

CC Well, what mode are yotf in on your computer now? 
S/C I just ran from prelaunch to checkout - at that time the 
comp light off - let's see if it comes back on now. Ok. It's 
back on now. Now we'll turn the whole computer off and see 
what happens. Now, I still get the computer running light when 
I've got the switch off. 

CC You still have the computer running light with the switch off 
S/C That's affirmative. 
CC . . 
S/C What? 

CC We Still show that the computer is on. 

S/C Affirmative - you show that the computer's on? 
CC That's what we show down here. 
S/C Ok. 



Mission Commentary Transcript Tape 133, Page 6 

CC Cycle it one time, now, Jim. 

S/C . . . 

CC Say again. 

S/C Yes. Can you tell what mode we're in down there? 

cc Affirmative. 

S/C Ok. We're going to catch-up as soon as it switches over there 

CC It's a catch-up. 

S/C Did it switch on? 

CC It sure did. Switch it back to off. 

S/C Houston . 

CC Go ahead, Jim. 

S/C What mode are we now? 

CC You're in catch-up. 

S/C Is that what it shows down there? 

CC It shows you in catch-tip and on, that's correct. 

S/C Ok. My ON/Off switch must have failed in the ON position. 

Hey, ground. 

CC Go ahead. 

S/C We're going to switch the IGS power off and let it go back 
to prelaunch and just turn the IGS power on. 

cc Just stand by on it, Jim. 



Mission Coinmentary Transcript Tape 133, Page 7 

CC Did you get that? 

CC Gemini 4, Houston Cap Com. 

S/C Go ahead. Cap Com. This is Gemini 4. 

CC Leave your computer the way it is for a few minutes . Ok? 

S/C Ok. I'll leave it switch off, in prelaunch, with the computer 

light burning. Actually, the computer's on, I guess. 

CC Roger. We got all the experts pouring through the books, 

here . 

S/C Ok . 

CC Hey, Jim. Did you have your HF on when you passed over 
Ascension in the last orbit? 

S/C Well, I did have my HF on but I was reading somebody in UHF. 
CC Yeah, they gave you a call. 

S/C I answered him UHF but I never got a response. 

CC Ok. Fine. Hey, we're still thinking down here. Gemini 

4, do you still read? 

CC Gemini 4, Houston Cap Com. 

CC Gemini 4, Houston Cap Com. 

CC Gemini 4, if you read turn your IGS off.

This is Gemini Control Houston, "jS hotirs Kl minutes into the mission 
on the 49th revolution. Just had a pass at the northern edge of the 
Carnarvon contact zope. We are satisfied now that in the pass that 
McDivitt heard our broadcast as he went down the Eastern Test Range. 
We are satisfied that he has left his computer switch in the ON position, 
and over on the upper right wall of the cabin over Ed White's ri^t 
shoulder, he has put a switch there, the IGS switch in the ACME position. 
Earlier, we had — indications were that we had asked them to put that 
IGS switch in the OFF position, but reconsideration with the Guidance 
Navigation and Control people here thought it best to put it in the 
ACME position, which means attitude control maneuver electronics. This 
will leave — this allows electricity to flow through the ACME circuits 
which control the maneuver thruster action. We expect contact with the 
Rose Knot Victor in 67 minutes from now. tfeanwhile, we have the tape 
for you from the Carnarvon pass. It is very brief and it is noisy. Here 
it is at this time. 

S/C Hello Carnarvon, Gemini IV, over and out 

CC Roger, is your computer switches in the ON position, your AC power 

switch In the ACME position. 
S/C Computer switch is ON and AC power in ACME, is that right? 
CC That's affirmative. 
S/C Okay. 

FLT Where did he have It? 

CC What position were you in? 

S/C It was in - . . . switch ON and AC power in IGS. 



Mission Commentary Transcript Tape 15^, Page 2 

CC Roger. I understand 

CC What load were you in? 

CC What computer load were you in? 

S/c Computer ON AC power switch in IGS 

CC Okay 

FLT Carnarvon ask him to describe again what happened when he turned 
the switch to the OFF position, and after he's done that , if he 
hasn't said so, ask him if he saw a mal . 

CC Roger 

CC Tell me what happened when you went to OFF position. 

S/C Carnarvon . . . Gemini IV 

CC I read you loud and clear.

Mission Commentary Transcript Tape 135, Page 1 

This is Gemini Control, 77 hours and 28 minutes into the 
mission and we've just started the 50th revolution. For the 
last revolution around the earth, we've had - encountered a 
little difficulty with the onboard computer switch. The ON/OFF 
switch has been acting up. We've tested the circuit breakers 
on it and looked at it. It isn't acting just exactly as it 
should. I am pleased to report that all other systems on board 
are entirely green at this time. This particular switch is 
the subject of considerable conversation that we have on tape - 
conversation first with the Coastal Sentry Quebec, then a brief 
conversation with the Hawaii station and then as the spacecraft 
swung down the western Central American coast, through Houston. 
It's also worth noting that throughout the course of this flight, 
we have mentioned time and again, Gus Grissom, the Capsule 
Communicator on this. shift, and at his side every day has been 
John Young who was also at his side some 76 days ago, during their 
flight in GT-3 . John, during the course of this flight, has 
been just as silent as he was during that GT-3 flight. Gus has 
done all the talking. We're prepared to play the tape for you 
now and we'll listen to that tape at this time. 
S/C CSQ, Cap, Gemini 4. 

CC Roger. Do you have a contputer malfunction light on? 



Mission Commentary Transcript Tape 135, Page 2 

S/C Negative. But I sure have a pretty combination of switches. 
I've got the ACME power on and I've got the computer on - 
my computer light finally went on and finally my malfunction 
light went off. 

CC Can you tell me when your computer light went on and when 
your malfunction light went off. 

S/C Ok. When we put the ACME .... I changed to ACME and I 
put the power in the computer, the computer light went off, the 
malfunction light came on, but the computer light came back on 
agadn and the malfunction light stayed on and then some bulbs 
got dimmer. A little while later, about three or four minutes 
after we went to ACME power, the computer went out. The malfunction 
light stayed on for about another four or five minutes and 
finally it went out. 
CC Roger. 

Flight: Send us a message on that CSQ. Describe it. 
CC Say again. 

Flight: Send us a teletype message. 
CC Roger . 

CC Flight, all of his systems look good. 

Flight: Roger. 



Mission Commentary Transcript Tape 135, Page 3 

S/C Station calling Gemini 4, say again. 

CC Roger, Hawaii calling Gemini 4. Would like to remind you 
you have critical tape dump over Guaymas. Acquisition time 
of Guaymas, 20 25 03. Did you copy? Over. 
S/c Negative. I did not copy. 

CC Roger. Your critical tape dump over Guaymas. Acquisition 
time, 20 25 03. Did you copy? Over. 

S/C You said we have a critical T/M duitvp over Guaymas at 20 25. 
CC Roger . 

S/C Who am I talking to? 
CC This is Hawaii. 

S/C Roger, Hawaii. Can you tell me how I am doing on my electrical 
power? 

CC Roger. Stand by. 
Flight: You're doing great. 

CC Roger. Flight reports you are doing great. 
S/C Above or below the predicted? 

Flight: He hasn't used as much as we predicted and we predict 
he's got plenty of power left. 

CC Roger. You have not used as much as predicted and should be 
well ahead. 



Mission Commentary Transcript Tape 135, Page 4 

S/C Rog . 

CC You're fat by apprpximately 160. 

S/C Roger. Understand I've got 160 amp power more than we had 
planned . 

CC That is affirmative. 
S/C Ok . 

S/C Have they got my computer figured out yet? 

Flight: Negative. 

CC Negative on that, Gemini 4. 

Flight: We're working on it. 

CC They're working on it at the present time. 
S/C Ok. 

CC Flight, Hawaii. 
Flight: Go ahead. 

CC We did send a TX. It was rejected on our first transmission. 
Retransmitted and it was accepted. 
Flight: Rog. 

CC All systems looked good on the ground. Negative malfunction 
light. 

Flight: Rog. 

CC Flight, Hawaii.

Flight: Roger. 

CC Gemini 4, Houston Cap Com. 

S/C Ok, Houston. This is Gemini 4. 

CC Roger. Gemini 4, we would like for you to bring your IGS - 
your power switch - ease your power switch back to IGS and your 
computer switch on. And we'd like for you to watch - when you 
do that we'd like for you to watch for a rise in amperage to 
make sure it comes on. 
S/C Ok . 

CC We want you to leave this on till you just about finish 
your pass over here. We want to check the computer memory. 
S/C Ok. Jt's going on now. 
CC Guaymas, go ahead with your pass. 

CCG We're having a little difficulty locking up on T/M. 
Flight: Roger. 

S/C Houston, Gemini 4. I've got the malfunction light on now. 
It won't go out. 

CCG Gemini 4, Guaymas Cap Com. 

S/C Roger, Guaymas, Gemini 4. 



Mission Contmentary Transcript Tape 135, Page 6 

CCG Roger. I'm not receiving T/M. I'm getting it intermittently 
now . 

CCG Gemini 4, Guaymas Cap Com. We're standing by for a tape 
dump . 

S/C Roger. You want me to dump it or can you just dump it by 
command? 

CCG You'll have to duiap it. 

S/C Ok. Tape playback coming on continuous. 
CCG Flight, Guaymas. 
Flight: Go ahead. 

S/C Be advised I can't get my malfunction light on my computer 
now. 

CCG Roger. Did you copy, Flight? 
Flight: He now has his mal light off? 
CCG He's got it on and he can't get it off. 
Flight: Rog. 

CCG Gemini 4, we've still not received your dump. 

S/C Ok. I've got the tape playback continuous. 

CCG Guaymas Cap Com, Houston E Com, get a transmitter on. 

CCG I have still no modulation, Gemini 4. 

S/C Ok. Stand by. 

Flight: Has he got the transmitter on? 



Mission Commentary Transcript Tape 135, page 7 

CCG That's affirmative. I've got a carrier. Flight. No 
modulation, though. 

Flight: You're sure that isn't the Aq aid? 
CCG Negative. People are cued up for a dump. 

S/C Guaymas, Gemini 4. All the switches and circuit breakers 
are on. You ought to be getting it. 
CCG Roger, stand by. 

CCG Flight, I think you're right. T/M says he can't tell for 
sure whether it's Aq aid or the dump. 

E Com: Guaymas, Cap Cpm, this is Houston E Com. Have that 

T/M switch to real time/delayed time and you'll get it. 

CCG That's how he turned it on, I assume. Gemini 4, Guaymas 

Cap Com. 

S/C Go ahead. 

CCG Did you place the telemetry switch to real time and dump 
time? 

S/C Real time and delay time? 
CCG That's affirmative. 

S/C Ok. You can't command anything on, that right? 
CCG I got it now, Gemini 4. 
S/C Roger .

This is Gemini Control Houston, 78 hoiirs and 11 minutes into the 
mission. Mission Director Chris Kraft has just advised the Coastal 
Sentry Quebec in the western Pacific to pass up to the Gemini IV space- 
craft in approximately 5 minutes the tlme-to-retro values for a 63-I 
landing. This would be in the primary landing zone for the 65rd revolution. 
We are now in the 50th revolution, and this pass is taking the spacecraft 
over the northeast coast of South America, During the course of that pass 
over northeast coast of South America, the pilots were to energize the 
flux gate magnetometer and the electron proton spectrometer, two devices 
used to measure the strength of the magnetic field which dips to its lowest 
point over the earth just off the coast of South America. Both pilots were 
scheduled to eat - they are scheduled to eat right now. They should have 
started a few minutes ago. In about half an hour, it will be Jim McDivitt's 
turn to go back to sleep. Flight progressing very nicely at this point. 
We still haven't quite figured out what's wrong with that computer switch 
which has been acting up, but it is not of critical concern. Reviewing the 
electrical circuits involved and hope to have a solution shortly. This 
is Gemini Control at 78 hours and 12 minutes into the flight.

Gemini Control here, 78 hours U5 minutes into the mission on the 
50th revolution. At this time, Jim McDivitt,who was programed to catch 
a little sleeps in this period, is still up. He is talking now to the 
Guaymas station as the spacecraft swings along the Mexican coast. He 
has been describing whether they are going to put their various items 
of equipment, got it all laid out, H just broke us up here by saying 
after reeling off a long list of storage spots, someone reminded him 
that it was pretty crowded up there and he suggests that we could just 
barely see out the windows. Earlier we had an outstanding pass in the 
Pacific area where he was in touch with the Coastal Sentry Quebec. 
Then the range tracker ship immediately after CSQ, and then Hawaii. Ihat 
tape is ready. We now have the tape and will roll it for you at this 
time. This is Gemini Control.

This is Gemini Control, 79 hours 8 minutes into the flight, on the 
51st revolution. The spacecraft just left the southeast coast of 
South America and entered dark — entered another night. It will 
probably be out of contact with our stations this pass. Q3ie pass will 
carry it over Pertoria and Tannarive. But Tannarive's voice contact 
reported up earlier has not functioned this afternoon. Then the pass 
will swing up across the Indian Ocean along the China coast and back 
across the Pacific. The shift is about to change again. The team led 
by Gene Kranz. Many of the flight controllers are coming in now, con- 
ducting the normal kind of changers shift briefing that goes on. 
This is Gemini control.

This is Gemini Control. It is 79 hours and 39 minutes 
since Gemini 4 lifted off at Cape Kennedy last Thursday morning. 
The spacecraft is now in its 51st revolution around the earth 
and at the present time is over southeast Asia on the night side 
of the world. We have just had a shift change here at the Mission 
Control Center. Gene Kranz has again taken over as Flight 
Director from Chris Kraft and his White Team has moved into the 
consoles. Before leaving the Flight Surgeon console at Mission 
Control Center, Dr. Charles Berry said the astronauts are in 
great physical condition. At this time, in spacecraft Gemini 4 
command pilot Jim McDivitt is a sleep period. Pilot Ed White 
is taking pictures of the attitude control thruster plumes, 
according to our flight plan. This is Gemini Control.

This is Gemini control at 80 hotirs and 8 minutes into the foiir-day 
flight mission of Gemini IV. Ttie spacecraft is on its 51 st revolution 
of the earth and is now over the Pacific Ocean. As the spacecraft 
passed over the Coastal Sentry Quebec our tracking ship in the Pacific 
a few minutes ago pilot Ed White received directions for test that may 
clear up the question as to wether or not the spacecraft computer is 
functioning properly. On instructions relayed to Gemini IV from the 
MCC, White turned the computer switch to OFF Position. He then turned 
on the AC power to the inertial guidance system and then again turned 
the computer to ON position. He was asked to let the computer run for 
approximately 90 minutes to two hours. This may warm up the switch 
mechanism if it had been cold. If the test is successful the computer 
will be left oh for the rest of the mission — the computer switch. 
Pilot White acknowledged the message. He also reported sighting 
tropical storm Victoria, located off the coast of Mexico. We will now 
play back the voice tape between the Coastal Sentry Quebec and the 
spacecraft. This is Gemini control.

regarding the computer problem. Do you copy?

landing point of Gemini IV will be at 2J degrees 29 minutes north 
latitude and T5 degrees 25 minutes west longitude. This is IkO miles 
due west from the initial Impact prediction. This change is due from 
the slight and expected variation in the actual insertion conditions 
during launch and in the expected variations in the ground track.

S/c Roger. Propellant quantity readout. Just a minute. 

It looks like about k8 percent. 
Flight Roger, I understand k-8 percent. There will be no medical 

data passed at Canaries this time around. Wo medical data 

passed at Canaries, 
S/c Okay. 

Flight And I've got a change to this Apollo landmark you've got coming 
up this rev. 



Tape 160, page 2 

S/C Roger, standby a minute. Okay, go ahead- 

Flight Okay. You can change — delete sequence 12 and sequence ik. 

You will he on this orbit, orbit 58 at time 09:^4-0:22. Minus 

6 degrees yaw and minus 5O degrees pitch. 
S/C Okay. It will be sequence number 1^+ at 09:40:22, minus 6 and 

minus 50. 

Flight Roger and mderstand that will be a sleep during this time, 

is that correct? 
S/C that's correct. 

Plight CJkay and we want to just advise you to use all the film you'll 
this is your last experiment. Use all the film you have at 
your option and Jim is here and we would like to discuss 
this reentry with you a little bit. One other thing, Jim, 
we have Increased the lifetime of your aft thrusters to 
151 ft/sec and you will see no split bums on OAMS retro. 

S/C Very good, very good. I was wondering what you were going 

to do about that. 

Flight We've been holding on to that for awhile. Diought we'd 
suz*prlse you. Here is Jim. 
Gemini IV this Is Shaky here. 

S/C Hello there. Shaky here, how are. 

Plight Fine. What is your feelings on a roll in reentry versus a 

90 degree bank angle? ¥e are recommending rollin here. 



Tape 160, page 3 

S/C Yeah, it's not very imaginative but it gets the job done so 

why don't we go ahead with it. 

Flight Roger, ^here is the format which we will send up to you for 
a rollin reentry, ¥e will give you the delta V and delta T 
for your OAMS bum. We will give you the GMTRC. We will give 
you a RET of . 05g. And then you will also get the RET 
of drogue, of main and of landing. Your procedure will be 
at retro to go'^l'ull left, heads down. At the RET of 05g 
you will go into a I5 degree roll rate. When you reach 
100,000, when the altimeter comes off the peg, go to full 
left. How does that sound to you Jim. 

S/C I think I blocked part of you out. Right at retrofire we go 

to full left, and at .05g or that time we go tol5 degree per 
second and at 100, 000 we go to full left again. 

Flight That's right. The only difference between the format before 
is that instead of the RET of i)-00,000 would give you 05g RET 
when you start your roll rate. 

S/C Okay, that sounds good. 

Flight 1h±s will give you a trim angle into the atmosphere, a roll 

rate and then a full left at 100,00 again for your drogue and 
main deploy. 

s/c Okay, very good. 

Flight Shades of Mercury, Jim.

up this one. That's what I say, not very imaginative but

Lucky, I'm going to try to hold up my end too. 
Remember when I said we'd never make a closed looper.

Yeah. 

Hay Jim, we are still going to pass you your updates for 60

been passing them, with exception of 65. !• 
That's affirmative. Don't change those . . the final one 
Roger. That will come up just as it has been coming up and 
you will get them at Canaries. 
Okay. 

Jim, what is your general physical condition? Are you feeling 
pretty tired now or you pretty good? 

No, I'm pretty sleepy and tired and I suspect Ed probably is 
too. 

Right 0. I understand you are pretty sleepy and tired.

This is Gemini Control, 93 hours, 9 minutes after liftoff. 
The Gemini 4 spacecraft is now over the mid-Atlantic at the 
beginning of the 60th revolution. We have a late weather 
report from the prime area which reads as follows: 

The U. S. Weather Bureau Spaceflight MeteotodiAgy 
Group said this morning that the weather conditions in the 
Western Atlantic Ocean remain very good for the termination 
of GT-4 some 300 miles east of Palm Beach, Florida this 
morning. The aircraft carrier Wasp reports scattered 
clouds, mostly above 1500 feet, together with visibility 
of over 10 miles. Southeast winds of little less than 15 
knots have raised the sea of about 3 feet, which is considered 
very good for the Gemini spacecraft. Isolated showers within 
a 50 miles radius will present no problems. Temperature is 
forecast to be about 78 degrees. This is Gemini Control.

CC: Roger, 15 minutes .ago. Jim, I'm going to pass you the 
general procedures for the reentry, you'll get the 63-1 updates 
and the details on your next pass over the states from Gus . 
The general procedure we'd like for you to follow is after 
retrofire, roll to the normal condition to a heads down 
position for full left to 400 K. We will give you an attitude 
angle to hold down to 400K. Then we'd like you to roll at 15 
degrees a second til the altimeter comes off the peg at approx- 
imate lOOK and back to full lift again til go.

This is Gemini Control, 95 hours and 40 minutes into 
the mission. We've just checked with the environmental 
control officer this morning and he advises 15 pounds of 
oxygen, both breathing and cabin pressurizing oxygen still 
remain in the Gemini 4 spacecraft and this usage conforms 
with the planned usage curve almost on the dot. In the 
OMS fuel we have 145 pounds remaining. Expect to use about 
130 pounds of that for the pre-retro orbital attitude 
maneuvering burn, which will precede the retrofire by 
some minutes. As we indicated earlier, the retrofire will 
take place slightly north of the Guaymas station and the 
preretro OMS maneuver will take place over the Hawaii station.

do that anyway, then I decided that I couldn't do it because 
I didn't have the response because we don't need to quickly

to reaffirm, we'd like no more than that 1 hour in the space- 
craft, get your suits off at your disgression if the spacecraft 



has no leak. The hatch - open hatch part is strictly your 



decision. It looks good in the recovery area at the present 
time for this and remember the pumping exercise we did at the 
time of the physical and the feet up would certainly be the 
preferable way. Are there any questions about this at all.

This is Gemini Control, 96 hours and 39 minutes into 
the mission with the spacecraft going over the African 
continent for the last pass in this Gemini 4 flight. During 
the interchange you heard live between the crew and the 
ground during the pass across the United States, there was 
a reference to Item "Bravo". This is a stimulant, it is 
specifically dexidrine you heard command pilot Jim McDivitt 
decline the use of it, he said neither crew member needed 
it, they didn't plan to use it. You will recall on Gordon 
Cooper's flight he did elect to take a little dexidrine 
prior to his reentry. The present calculation calls for 
OMS pre-retro burn over Hawaii at 10:44, starting at 10:44 
Central Standard Time and ending about two minutes and 40 
seconds later. The recovery leader is confering at the 
present time with the flight director. He advises that the 
recovery forces should have a good plot on a splashdown 
point about 5 minutes after retrofire. This will be based 
on radar data from White Sands, from Eglin, and finally from 
Grand Bahama Island. This is Gemini Control.

CC Hawaii has had TM LOS, Fll^t, Radar LOS. 

Flight Roger. Well done. 
CC We going to correct on one second. 

Flight Say again. 

CC Are you going to correct for that one second overturn. 

Flight Negative. It was not 1 second overburn. Yes, it was, 

I'm sorry. Negative. 
CC Roger, we'll go with it.

This is Gemini Control. We have completed the OAMS — . pre- 
retro OAMS burn pver Hawaii. He should have expanded about a hundered 
and 50 pounds of fuel. This would leave about I5 pounds of fuel in his 
primary tanks. Just prior to his retro-maneuver over Guaymas he will 
jettison the equipment section of the spacecraft and then for attitude 
during reentry he will depend on his reentry control system. He has 
two independent rings of 8 thrusters each. Each thruster 25 pounds. 
The reentry control system functions off separate tanks each with 
about 35 pounds of fuel available for attitude control. California 
is the next station which should acquire at 5I and one -half minutes 
after the hour. Guaymas should have him at almost 'pk minutes after 
the hour with the retrofire time planned for 56 minutes. During the 
retrofire maneuver, the spacecraft will be pitched down at 30 degrees 
immediately after completion of the maneuver, that will be pitch -down, 
and the Pilots will have their heads up. Immediately after the retro- 
fire maneuver, they will roll the spacecraft around I80 degrees and 
assume an angle of 23 degrees off the horizon. They will maintain 
that angle till they reach a point about h-00 000 feet above the earth 
at which point they will start a roll rate just as we did at the Project 
Mercury Program. A roll rate of I5 degrees per second. Hhis is Gemini 
Control.

This is Gemini Control Houston. One minutes ago the 
Guaymas station established contact witn Gemini 4. *^e 
are standing by for the retromaneuver . Right about now 
Jim McDivitt should be jettisoning the equipment adapter. 
He has just confirmed the adapter has separated from that 
Gemini 4 spacecraft its leaving the retro adapter section 
at 30 seconds to retrofire. He has armed the retrorocket 
circuits and we are counting down for retrofire, 6, 5, 4, 3 
2, 1, retrofire. We are standing by, we have a report on 
one firing, rocket 3 and rocket 2 have fired, rocket 4 has 
fired, Jim McDivitt confirms that all 4 have fired. Let's 
tune in on that conversation with Guaymas. 
CC: Do you confirm retro set 
S/C: Ed says he sees the pump package 

CC: Say again 

S/C: Ed says he saw the pump package 

CC: Ah roger, their own their way. Flight. 
F : Roger 

CC: Flight from Guaymas CapCom 
F: Go ahead 

CC: Did you copy that the auto retro was one second prior 
to my count? 
F : Roger 



Mission Commentary Transcript Tape #182, page 2 

CC: Still looking good. Flight, I 'm getting activity on 
ring A and B 
F : Roger 

This is Gemini Control. We have confirmed the retro 
set, in our other ear we bring in lots of activity in the 
Atlantic Ocean as the planes are establishing their call 
and they are poised and waiting for Gemini 4 to splash down 
some 440 miles east of the Cape. 

CC: Stand by for a mark at TR+3 minutes. Mark, 3 minutes. 

GCH Our White Sands Station is tracking the spacecraft 

right now. This radar data and that from the Eglin AFB 

in Florida will help us establish with considerable finality 

the splashdwon point. 

CC: Gemini 4, Houston CapCom. 

S/C : Go ahead, Houston, Gemini 4. 

CC: Roger, you started your rolling reentry. 

S/C: Roger, I have. 

CC: Roger. Your weather is still very good, Jim. 
S/C : Okay 

GCH Jim McDivitt advises he has started his rolling reentry. 
He has started his roll rate. 

S/C: (Garbled)

This is Gemini Control. Gus Grissom has just raised Jim 
McDivitt. He came back with "we're 5 t)y 5 up here" or something 
like that, it was a very faint transmission. Grissom is advised that 
we should have a helicopter over the spacecraft about the time it hits 
the water. Stand by for further transmission. 

This is Gemini Control. We eire estimating drogue chute 
in about 10 seconds. Stand by for drogue chute. We estimate he is 
at about hO 000 feet now and he should have a drogue chute out although 
we have not heard a confirmation. 

We have a report from the Wasp that it is in contact with the 
spacecraft. We are not monitoring any transmissions here, they are 
on the HF circuit and we really didn't have too much hope of reading 
those transmissions, but we should be hearing from the Wasp. 

From the deck of the Wasp we are advised that they have had 
a transmission from McDivitt that says they read him loud and clear. 
At this time McDivitt and White should be on their main chute. 

As yet we I ve had no visual sightings but we do have some 
helicopters vectoring on the area. The astronaut reports to the 
Wasp that he is on his main chute and everything looks fine. He has 
been advised by Gus Grissom here, we don't know whether the trans- 
mission reached him or not, it was backed up by a transmission from 
the carrier I'm sure, that a helicopter will be over him in about 
5 minutes.

The two pilots have advised the Wasp that they are feeling great. 

s/c ^ 

Flight We can't read you Jim, you're fading out too much. 
Flight Okay, the R and R can is floating by. 

Flight We figure you ou^t to he touching down in about 20 seconds. 

Gus Grissom is advising Jim McDivitt that he shoiild be touching 
down within the minute. We are standing by for additional reports from 
down range. The circuit is very noisy and almost unreadable. Hiis is 
the HF circuit. I emphasize this is the circuit from the spacecraft. 
Communications have been excellent with the DOD forces in the Atlantic. 

This is Dallas . . . aboard the Wasp. The Wasp ... 

This is Gemini Control. Our latest radar fix from the Wasp 
indicates the ship is about kO miles from the spacecraft. The space- 
craft ho nautical miles uprange from the Wasp. There are at least 
2 helicopters in the area. They shoxald be overhead momentarily. We 
are still standing by for an advisory from the deck of the Wasp. 

We have a report from down said that a helicopter has the 
spacecraft in visual sitting. It is a confirmed report. He is 
approximately 5 miles away from it. 

This is Gemini Control. We are assuming the spacecraft 
splashed down at approximately I5 minutes after the hour. That is, 
approximate splash time. We will confinn it momentarily.

That a 2 engine airplane, an S2E, which has been established as 
the on-scene commander of this recovery situation is now in voice contact 
w ith the spacecraft. They advised the Wasp that everything is okay. 
Hiey were in contact with the spacecraft at 1^ minutes after the hour. 

From downrange we are advised that the Astronauts have requested 
a helicopter pickup. They are on the water and we are standing by. The 
surgeon here is considering a helicopter pickup. We should know momentarily 
what his decision is. 

Our best estimate right now on the landing point is 25O miles 
north of San Salvador or 59O miles east of Cape Kennedy. 

From the Wasp we are advised that the pickup helicopter, the 
copter that will pick up the two pilots will be over the spacecraft within 
5 minutes from now. The local time here is 20 minutes after the hour. 

Admiral Cormick on the Wasp has just ordered the helicopters 
to proceed with the pickup of the two pilots and to return them to the 
Wasp. At last report, they were I8 to 20 miles from the spacecraft and 
were proceeding toward it. 

This is Gemini Control. The Wasp now estimates it should 
be along side the spacecraft or actually pick-up the spacecraft in 
about 1 hour and 20 minutes from now. They are estimating 12 c.s.t. 
that they should be alongside for pick-up. The helicopter estimate 
meanwhile for pick-up has been put-off iintil about 10 minutes from 

now. This will make it shortly after the half -hour. This is Gemini 
Control standing by. 



Mission Commentary Transcript Tape I85, Page h 

The helicopter, an SH5, a Navy helicopter, which is a twin 
engine jet turban type helicopter is in the area of the spacecraft 
right now. He has been designated to pick up the pilots. 

The helicopter in the recovery area has the green dye which 
is put out by the spacecraft on landing in sight. We have not yet 
heard wheather the hatches are open or closed. We are standing by 
for additional information. 

niis is Gemini Control. The pilot of the helicopter on 
scene reports the spacecraft is riding very nicely in the water, 
and everything looks fine. That was the pilots report. The pilot 
of that helicopter is Commander Clarence 0. Plske. The helicopter 
is designated number 64. Off the Wasp. 

From the Wasp, we are advised that their present position 
is some h2 nautical miles from the spacecraft. They are estimating 
about 85 minutes before they are on scene and we are standing by to 
get some word from the Wasp as to whether the pilots are In fact in 
the helicopter or not. 

From the deck of the Wasp, we are advised that 2 more recovery 
helicopters are in the area approximately 5 miles from the spacecraft 
and are standing by. 

The flight surgeon on the deck of the carrier Wasp, Dr. Howard 
Minners, has advised that he Is most encoviraged by the sound of Jim 
McDivxtt's voice. He has just been in contact with him. We could 



Mission Commentary Transcript Tape 185, Page 5 

not monitor the situation here, but Dr. Minners says he is most encouraged 

with the sound of the report. This is Houston standing by. 

We are -advised by the Wasp that on being told that swimmers 
would be deployed shortly to ready the spacecraft for pick-up. Jim 
McDivitt came back with the reply "Hoorah, hoorah, we are going to the 
Wasp". 

We are just checking our notes here in the Control Center and 
we are — our best estimate on splash down right now is 12 minutes and 
50 seconds after the hour. Biis contrasts with the I3 minute estimate 
we gave earlier. This is Gemini Control standing by. 

Prom the Wasp, we were advised that the first of the swimmers 
is poised and ready to leave his helicopter. Standing by. Meanwhile 
in the Control Center someone in the Pli^t Planning Department has 
put up a slide on the monitor which says "End of the flight plan," 
and they suggest we tune in for GT-5. 

We are advised that one raft and one swimmer are in the water 
near the spacecraft. The procedure is the first thing the swimmers do 
in the water is to check on the condition of the pilots, get an eyeball 
verification of how they look and how they feel. Then they proceed 
to put a large flotation collar around the spacecraft to assure sea- 
worthiness until pickup which should come in about 1 hoiir and 15 minutes 
from now. 

We have additional swimmers in the water right now and they 
are now attaching the flotation collar to the spacecraft. 

At last contact, the Wasp reports that Jim McDivitt advised 
both he and Ed White were feeling great. 



Mission Commentary Transcript 



Tape 183, Page 6 



This Is Gemini Control. We are advised that the flotation 
collar Is just about attached to the spacecraft. They are now 
finishing the last bit of strapping. We as yet have not heard 
whether the pilots have left the spacecraft. We are standing by for 
that Information. 

The wasp at this time is 36 nautical miles from the spacecraft. 
56 nautical miles and proceeding at 30 knots toward the spacecraft. We 
are further advised that Jim McDivltt declined to leave the spacecraft 
until he was assiired the flotation collar was securely attached to his 
craft. We are standing by for any further information on the Pilot 
pickup. 

!Ihe latest word is that the collar is attached. We are advised 
here in Houston that the collar is inflated and looks good. 

In the recovery area we are advised we have k helicopters and 
1 fixed wing aircraft, which would be the on-scene comnianders aircraft 
in the area. From the Wasp we are advised that again the pilot's report 
both are In good shape and are hungry and they emphasize the word hungry. 
The pilots are in good shape and hungry. 

We are advised that the astronauts plan to stay in the space- 
craft until - for the len^h of time that it will take to get one more 
blood pressure reading. You recall that before retrof ire they were to 
obtain several blood pressure readings while still in the spacecraft 
while they are still in their spacesults, Ttiey are apparently going 
to take one final blood pressure reading before departing their Gemini 
TV spaceship. 



Mission Commentary Transcript Tape I85, Page 7 

We are advised that the hatch is open now on the spacecraft. 
Hiey did not say vhich hatch, but we would assume that it was the 
right hatch. We will stand by for confirmation. 

And the swimmers in the water around the spacecraft have just 
given the helicopter on scene a thumbs-up signal indicating the pilots 
look great to them. 

George, did you hear that the hatch is opening and that the 
swimmers report they are in good shape. 

- Hiis is Gemini Control. Some times on these reports at 37 min- 
utes after the hour the rescue helicopter coming in was reported in the 
area ready to drop the pick-up harness. At the Same time both astronauts 
reported they were in good shape and hungry, as we reported, and now we 
are advised that one astronaut has emerged from the spacecraft. We 
don't know which one.

GCH: The on-scene helicopters report that the right hatch 
is open. At 42 minutes after the hour, one of the astronauts 
emerged, we still don't have his name. And the Wasp now 
advises whichever astronaut was standing up in the spacecraft 
and appeared to be coming out had a brief chat with the 
swimmers and sat back down. We still don't know his name. 
More than likely it would be Ed White - that's the right 

now 

hatch. We're advised from the Wasp that one astronaut is/in 
a raft alongside the spacecraftf we still don't have his 
name, but. he has his water wings inflated and he is apparently 
standing by for a helicopter pickup on the helicopter hoist. 
And now from the Wasp we are advised that both men, both men 
are in a raft alongside the spacecraft and a helicopter is 
preparing to pick them up. Before departing the spacecraft 
apparently Ed White did a few quick standup type exercises. 

And from the Wasp we are advised that the sling from 
the helicopter is now being lowered to pick up one of the 
astronauts. Our communications this mornir^g with the Wasp 
have been outstanding. We've never had a better circuit 
into the Atlantic Ocean. 



Mission Commentary Transcript Tape # 184, page 2 

And we have one astronaut in a sling, on the way to 
the helicopter. No name. We're estimating its about a 
30 foot long hoist, it would have deployed at 30 feet and 
he would be brought in on a winch into the helicopter. 

The wasp, meanwhile, steaming at 30 knots, is now 
reportedly 28 miles from the scene-. We are advised that 
a second helicopter is being directed to pick up the parachutes 
the spacecraft, the spacecraft, on water, still floating. 

This is Gemini Control. Our plotboard from our recovery 
room here in Houston shows that the first astronaut was in 
the sling at 47 minutes after the hour. 

One astronaut is about to enter the helicopter, the 
other is waiting in the raft for pickup. Now the second 
pilot is on the hoist and on his way into the helicopter. 

Now we are advised that both astronauts are onboard 
the helicopter, both astronauts on board. We do not know 
whether they still have their helmets on or not, but we 
assume they would have taken the helmets off, but, they 
would have kept their spacesuits on. 



Mission Commentary Transcript Tape #184, page 3 

We are advised the helicopter is now proceeding toward 
the Wasp, we have no estimate as yet as to when the helicopter 
will be over the Wasp, we are standing by. 

Both astronauts were aboard the helicopter fifty minutes 
after the hour. Meanwhile a second helicopter which was to 
pick up the spacecraft parachute reports that apparently 
the chute has sunk and, uh, we don't know whether they have 
abandoned the search or not. It's certainly not a critical 
item.

The Wasp reports both astronauts in the helicopter, 
smiling and in^ great spirits, they're about 30 miles from 
the Wasp right now, proceeding toward it. Meanwhile, here 
in the control center, Mission Director Chris Kraft xx has 
lighted up his post-splashdown cigar. He's puffing on it 
merrily, a big cloud of smoke enveloping his head. He's 
a very happy man. 

This is Gemini Control. We're advised that the helicopters 
should be over the Wasp at 10 minutes after the hour about 17 
minutes from now. 

Thisis Gemini Control. We've just been advised from 
the Wasp that approximately 90 percent of the crew of the 

wasp should be The helicopter carrying the astronauts 

is now about 10 miles away. It's in view of the Wasp. They 
are rolling out the red carpet on deck, preparatory to 
receiving the astronauts. From the helicopter we are advised 
that a Dr. on board has taken a quick check of the men and 
he reports that they are in great shape. Great shape, they 
are still in their space suits. 

Roger, I understand the Wasp can not see the helicopter 
visually. 



Mission Commentary Transcript Tape 186, page 1 

From the Wasp we are advised that several helicopters 
remain on the scene, making a search for the radar and reentiy 
section of the spacecraft, that's the forward tip of the 
spacecraft out on the nose of it and in some past flights 
we have been successful in recoverying that. We apparently 
did lose the parachute, the spacecraft parachute, which is 
jettisoned on touchdown. It usually lands within a half 
a mile of , withina very few feet, actually,/ of^he spacecraft, 
floats away rather quickly. 

This is Gemini Control. The Wasp is standing by to 
receive the helicopter bearing Ed White and Jim McDivitt . 

And the Wasp advises that Admiral McCormick, Captain 
Conger is standing by on the deck of the Wasp, the Marine 
guard aboard has an area roped off X in preparation for 
receiving Jim McDivitt and Ed White. 

This is Gemini Control. Here in the control center 
there must be fully 50 people. Project officials from the 
Gemini office, there's Dr. Gilruth, Director of the Manned 
Spacecraft Center, has just come in and shook Chris Kraft's 
hand vigorously. They're all smiles. 



Mission Commentary Transcript Tape 186, page 2 

We're advised that the helicopter is about 20 feet 
off the flight deck of this time, we can hear the engine 
noise in our headset. And the prime helicopter touched 
down at 9 minutes after the hour, the helicopter is on the 
deck at 9 minutes after the hour. 
;^ Marine guards are rolling out the red carpet. 

And the door of the helicopter is open. Jim McDivitt 
is steping out to a tremendous round of applause from the 
sailors out on the deck of the Wasp. He is followed by 
Ed White. 

Admiral McCormick is congratulating the pilots right 
now. He's waving to the crew. They are moving down 
the red carpet at this time toward the medical area where 
they will take a quick post-flight physical. I can hear 
the band playing in the background. They have entered 
the island area of the ship, headed for the Wasp sick 
bay for their quick postf light physical, their first of 
several. 

We are advised from the Wasp that all the flags are 
waving, including the NASA flag, the flap of the WASP, 

the United States Flag, and of course the Marine Corps 



Mission Commentary Transcript Tape 186, page 3 

flag, and it sounds like a pretty turbulent scene. 

This is Gemini Control. At 13 minutes after the hour. 
From the Wasp we are advised that the pilots look to be in 
great spirits as they walk away from the heicopter. They 

carry nothing we have an additional report coming in, 

I say again, they reportedly look great. He said he could 
observe that they definitely needed a shave, both of them. 
This is Gemini Control, standing by.
