CAPCOM - - so that we can change the variable parameter 

downlist so we can see the COAS CAL data and when yor, do the COAS 
CAL at your lower cabin press, we do not want you to update. We 
don't want to take those marks i n - o the software. We just want 
to see the data so we can see if there's any chan<j** at 10.2 
cabin. Also, the GN&C want you to know that your" "Us t COAS CAL, 
Vance, was one of the better ones they've seen clown here. 

SPACECRAFT Okay, real good. We'll ,o one update, then we'll 
just copy the numbers. 

CAPCOM Also, have one note on your presleep activities for 

cabin repress when you're ready to copy. 

SPACECRAFT Stand by one. 

SPACECRAFT Okay, go ahead. 

CAPCOM You've already gotten your supply water dump bravo 

to 20% but for your 10.2 cabin maintenance we would like you to 
delete the cabin repress. So no cabin repress is necessary. 
We'd also like you to reset a couple of the upper limits for PP02 
alpha and bravo and those are hardware changes. We will do the 
software limit changes for you. Channel 34, CP02 alpha, high to 
3.1 volts DC and Channel 44 PP02 bravo, 3.0 volts DC higher 
limit, over. 

SPACECRAFT Okay Mary, understand that in a couple of days or 
so we do not have to repress the cabin which is real good news. 
And PP02 alpha and bravo you'll change the software but you want 
us to change the caution and warning hardware for 44 to 3.0/3.0 
and say again 34. 

CkPCOM Roger, Vance. Saying again 34. PP02 alpha is 3.1 

volts DC for your high caution and warning. 

SPACECRAFT Houston, Challenger. 

CAPCOM Channel, Challenger, Houston. We were having some 

comm problems on air-to-ground 1. Now how do you read? 

SPACECRAFT Okay, read you fine. Understand you do not want , s 
to repress and was that, when was that repress to be. I'll have 
to check the CAP. 

CAPCOM Roger, Vance. That's just the nominal cabin 

repress for presleep and it would be this evening only. During 
the presleep activities do not do your cabin repress. 

SPACECRAFT Okay, got you and okay. On the PP02 alpha and 
bravo, caution and warning 34 is I believe 5 1 or rather 3 1. 



STS-41-B AIR/GROUND TRANSCRIPT tl69j 037:19:29 2/6/84 PAGE 2 

CAPCOM That's affirmative, 3.1. That's the high limit. 

SPACECRAFT 14 to 3.1 and, I'm sorry. 44 is 3.0/3.0 and high 
limit on 3 4 is 3.1 and say the other limit again. 

CAPCOM Roger. Channel 34 which is PP02 alpha high 

hardware limit 3.1 volts DC and engineering units 3.1 psi. 

SPACECRAFT Okay, copy. 

CAPCOM Challenger, Houston. Also you should have 

teleprinter messages 27 and 28 onboard now. 

SPACECRAFT Okay, we'll go look fc them, 

CAPCOM Challenger, Houston. Also requesting a time tag on 

your activation of the GAS group bravo. 

SPACECRAFT I got to get that for you. Mary. 

CAPCOM Okay, thanks, Ron. 

CAPCOM And Challenger, Houston. Back on your aft panel, 

your encryption selection switch - you can go hack to bypass at 
this time. 

SPACECRAFT In bypass now. Houston, Challenger, GAS group 
bravo activated at 5 plus 56. 

CAPCOM Roger, copy 5 plus 56 on GAS group bravo. Thanks.

CAPCOM Roger, copy, 5+56, on GAS group Bravo, thanks. 

CAPCOM Challenger, Houston, with you through Santiago for 

5 minutes. 

SPACECRAFT Hi, Mary, got you loud and clear. 

CAPCOM Got you loud and clear too. We'd sort of like to 

check and see whether you got teleprinter messages 27 and 28 
okay. 

SPACECRAFT That's affirmative, Mary, we have them onboard, and 
looking at message 27 regarding the therapeutic aspirin, for 
decompression, be advised that EV 1 and 2 took two aspirin this 
morning about an hour prior to cabin depress at 10.2. And we're 
planning on taking 1 a day there after. Is that satisfactory, or 
do you want us to take another two tonight, and then one every 
morning, oyer. 

CAPCOM Roger, Bruce, that is satisfactory, and on that 

schedule we do not want you to take two more aspirin tonight, 
just carry on the way you were planning on originally. 

SPACECRAFT That's what I really what I thought the plan was, 
and we're sticking to it. 

CAPCOM Roger, Bruce, well I think they were just trying to 

remind you to take some aspirin in case you forgot. And 
Challenger, Houston, have a question from the cinema 360 folks. 
For Cecil B. McNeir, if he's available. 



SPACECRAFT Go ahead. 



CAPCOM Roger, the guys said that the set up looked real 

nice, and they'd appreciate a read down of the footage obtained 
on magazine 2, and other comments on the movie light and use of 
the slate and lightmeter would also be of interest. And this i 
of your 360 of the deploy. 

SPACECRAFT Okay, Mary. On the, setting the 360 up, I took at 
it, an incident lightmeter reading of about oh, 3 minutes before 
deploy, latest possible minute. And came up with a setting of 
slightly over F4, so I shut it between F4 and F5.6, over. 

CAPCOM Copy. 

SPACECRAFT Okay, Mary, and to continue that report, when we 
finished the Palapa deploy there was about 60, 60 feet of film 
remaining. Just as you called, I was just finishing off the 
final 60 feet on some footage of Bob taking some shots out of the 
overhead window on his back. And we've got Hoot floating in and 



STS-41-B AIR/GROUND TRANSCRIPT tl70j 37:19:35 2/6/84 PAGE 2 

out of the flight deck, from the middeck, and (garble) . That was 
shot at the same ; between 4 and 5.6. 

CAPCOM Roger, copy, we're going LOS at Ago, we'll pick you 

up at Botswana if not TDRS at 7:17. 

SPACECRAFT Okay, (garble) cinema 360 meg for the RMS. 
CAPCOM Roger copy, thanks, Ron. 

CAPCOM Challenger, Houston, back with you through TDRS. 

SPACECRAFT Hi, Mary, you're loud and clear through TDRS. 

CAPCOM You're loud and clear too. Challenger, Houston, 

one more question from the 360 folks on the lighting used. 

SPACECRAFT Go ahead, Mary. 

CAPCOM Roger, they wanted to know whether the lighting was 

bounced or direct? 

SPACECRAFT Lighting was bounced off the starboard wall, for 
both of the scenes I described, both the Palapa deploy and the 
footage of the photography. We used a window shade for the 
Palapa deploy and I used a wall for the photographic scenes, we 
had pretty high lighting in both cases, and it seemed that the 
wall was adequate in the case of, for the second case. So we 
used the window shade, right over Hoot's head, right behind his 
seat, over. 

CAPCOM Roger, copy, thanks a lot, Ron, I appreciate all 

the information. 

SPACECRAFT Houston, Challenger. 
CAPCOM Challenger, Houston. 

SPACECRAFT Mary, we are reinstalling the COAS, we decided to 
take it out for the deploy since we had so much gear up in the 
windows, so -

CAPCOM Challenger, Houston. 

SPACECRAFT Mary, we are Reinstalling the COAS. We decided to 
take it out for the deploy ^ince we had so much gear ud in the 
windows. So that's just to ; let the GN&C people know that it was 
taken out and is being reinstalled. 

CAPCOM Copy that, understand. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston. Go ahead. 

SPACECRAFT Yes, Mary, you might mention to the cinema 360 
folks I just loaded up the third magazine. Did so with some 
difficulty. It appears that the film was deformed, the part that 
had been, that is exposed outside the magazine and the camera's 
mechanisms were not engaging the perforations of the film 
evenly. he film was sort of wrinkled and wavy and it just did 
not go through smoothly. Played abound with it and I worked it 
through slowly until I got the damaged part through into the 
magazine, cxosed it up, tested it so the magazine works well but 
I almost called you on it a while ago. So we have the third 
magazine loaded for the RMS tomorrow and we'll get any other 
interesting footage we can, over. 

CAPCOM Okay thanks, Ron. Copy and understand. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston. Go ahead. 

SPACECRAFT Mary, we just completed an IMU align. Did you see 
it? 



CAPCOM 
error and time 



Vance, this is Houston. We would like the angle 



SPACECRAFT Understand just the angle error. 

CAPCOM That's affirmative, angle error and time. 

SPACECRAFT Okay. Angle error was zero. Execution time was 3 
days, 7 hours, 16 minutes,, 30 seconds. 

CAPCOM Copy. That sounds good. 

SPACECRAFT Right.

SPACECRAFT Okay. 

PAO Mission Control Houston. 3 days, 8 hours, 29 

minutes. Final messages being prepared for the crew before 
they're put to bed for the night. About 30 minutes remaining 
before their scheduled sleep period. Flight Controllers here 
reviewing those remaining items that they have to get all the 
systems squared away to allow the crew to get a full night's :est 
before the EVA activities in the morning. We have a statemen: 
here regarding the Palapa satellite. Hughes tracking personnel 
have confirmed that the Palapa satellite cannot be found in hs 
expected orbit. Repeating that statment about the Palapa 
satellite, Hughes tracking personnel have confirmed that the 
Palapa satellite cannot be found in its expected orbit. We have 
about 37 minutes remaining in this TDRS pass although the final 
verbal contacts with the crew are expected only shortly and they

PA0 Mission Control Houston, Orbiter Challenger now on 

orbit 55, passing across the Saudia Arabian peninsula. Here in 
the Mission Control Center the planning team is taking over and 
is putting together a schedule for tomorrow's activities. 
They're looking at nominal EVA with three small additions, 
should they be possible. The first is a plan to bring in camera 
D, the alien camera out in the payload bay and change that out 
with one of the cabin cameras. The second contingency addition 
is to fix the thermal blanket on the Cimena 360 GAS caniste. 
And the third is to repair a microswitch on the SPAS payload. 
The mass spectrometer has a small problem which is thought to be 
a microswitch and they're going to try to change that out. But 
those EVA tasks have been sent up to the crew with the caveat 
that they're not to impact planned tasks or timelines of the 
nominal EVA. And the planning team will be putting together an 
idea of how that can be done. Orbiter Challenger currently in a 
157 by 150 nautical mile orbit and FIDO reports that weather is 
good at all continental United States landing sites for Tuesday 
should an early landing be necessary. We're still expecting 
again, our change-of-shi f t briefing at approximately 4:30 p.m. 
building 2, room 135. At Mission Elapsed Time, 3 days 9 hours 8 
minutes this is Mission Control Houston. 

PA 0 Mission Control Houston. We expect that the change 

of shift press conference originally scheduled for 4:30 p.m. will 
be delayed until approximately 5:00 p.m. this afternoon and that

over Australia on orbit 59, and we're wondering here at JSC 
whether there's any need to have a press briefing, the regular 
change-of-shift briefing at 12:30 a.m. this morning. We suspect 
there is no need, and toward that end, we'd like to ask any news 
media people, if they do have a desire to hold that briefing, 
that they call the Kennedy Space Center newsroom, or the Johnson

PA0 ...the KSC newsroom. At Mission Elapsed Time 3 

days 16 hours 11 minutes, this is Mission Control, Houston. 

PA0 Mission Control, Houston. The Orbiter Challenger 

has now entered orbit 60 and here in the Mission Control Center, 
we have gone ahead and canceled the 12:30 a.m. change-of -shi f t 
press conference. Again that briefing is cancelled. At Mission 
Elapsed Time, 3 days 16 hours 31 minutes, this is Mission 
Control, Houston. 

PA0 This is Mission Control, Houston. The Challenger 

on its 60th orbit of the Earth at Mission Elapsed Time 3 days 17 
hours 13 minutes. Data shows that two of the cathode ray tube 
displays in the flight deck have been activated, indicating that 
the crew is awake and active in the Orbit e, . There has been no 
wake up call as yet but we expect that wi;l o .cur when we 
reacquire signal through Yarragadee in abc't * minutes from 
now. This is Mission Control, Houston. 



(wake-up music) 



CAPCOM Good morning Challenger, Houston is with you. 

SPACECRAFT Morning John. How do you hear? 

CAPCOM Roger, you're loud and clear. 

SPACECRAFT Okay, thank you for the music again, that's 

great. We, I just read the teleprinter, the news, and that blows 

our minds. 

CAPCOM Roger, understand. Certainly as you know, Vance, 

everything that the spaceship did and all the procedures that you 
did were absolutely correct and they were done flawlessly and it 
blew our minds too. And we're having, as you can understand, a 
lot of ensuing assessments still going on. 

SPACECRAFT Yes, we can understand. 

CAPCOM And by the way, the wake-up music this morning was 

by the courtesy of the Air Force Academy Chorale.

CAPCOM ... as you can understand a lot of ensuing 

assessment is still going on. 

S. . 'CRAFT Yes, we can understand. 

CAPCOM And by the way, the wake up musi- this morning was 

by the courtesy of the Air Force Academy Chorale. 

SPACECRAFT Very nice. Sounded great. 

CAPCOM Roger and we're with you for another 2 and 1/2 

minutes over Yarragadee. 

PA0 This is Mission Control, Houston. Wake up music 

was an armed forces medley which covered three of the services. 
The Marine Corp., of course is Vance Brand's alma mater. He's 
now a civilian but was originally trained as a Marine Corp 
pilot. The Navy hymn in honor of Mission Specialist, Bruce 
McCandliss and Challenger Pilot, Hoot Gibson, both Naval 
Officers. And the Army song honoring the nation's first United 
States Army Astronaut, Bob Stewart. And the music was performed 
by guess who, the U.S. Air Force Academy Chorale. And Vance 
Brand ' s ... 

CAPCOM Challenger, Houston, we're going to leave you here 

for a couple of minutes. See you at Orroral. 

SPACECRAFT Okay Houston, see you at Orroral. 

PA0 This is Mission Control, we have a brief keyhole 

that we'll pass through here before we pick up Orroral for 
another 4 minutes of air-to-ground. And Vance Brand, 
acknowledging the teleprinter message and reacting to the news, 
the first indication that the crew has gotten concerning the 
failure of the PALAPA satellite to achieve orbit. Mission 
elapsed time is 3 days, 17 hours, 29 minutes, this is Mission 
Control, Houston. 

CAPCOM Challenger, Houston's with you through Orroral for 

4 minutes. 

SPACECRAFT Roger, loud and clear. 

CAPCOM Challenger, Houston, we're going LOS here in 30 

seconds, we'll see you TDRS at 17 plus 51. 

PA0 This is Mission Control, we're processing TDRS data 

now at mission elapsed time, 3 days, 17 hours, 52 minutes. 

CAPCOM Challenger, Houston's with you through TDRS. 



SPACECRAFT Got you loud and clear through TDRS, John. 



STS-41-B AIR/GROUND TRANSCRIPT tl80j 038:06:25 2/7/84 PAGE 



CAPCOM Roger, you're loud and clear, too. Challenger, 

Houston, be advised in a couple of minutes, we're going to be 
running an encryption test of our launch config over MILA and 
Bermuda, so I'll be giving you a call to turn your encryption ON 
and then your encryption OFF. So if you have somebody back by 
AIL in about a minute, I'll give you a call and ask you to put 
the encryption to TR. 

SPACECRAFT Okay John, we'll stand by for that. 

CAPCOM Challenger, Houston calling. If you could take th 

encryption and go to TR now, please. 

SPACECRAFT Okay, encryption going TR. 

CAPCOM Thanks a lot, Hoot. 

SPACECRAFT Houston, Challenger. 

CAPCOM Roger, go ahead. 

SPACECRAFT Yes John, I just wanted to see if, well if we had 
you with us and if you saw the IMU alignment angles? 

CAPCOM We didn't see the angles, we're interested in the 

data. 

SPACECRAFT Okay, I'll read them to you when you're ready. 
CAPCOM GNC is ready. 

SPACECRAFT Okay, stars, it was a roll star tracker align, it 
was stars 25 and 15, angle error 0. I'll read the delta angles, 
reading across all the X's, -0.04, -0.16, -0.04. Reading across 
the delta Y's, +0.08, +0.02, -0.10. The delta Z's, +0.08, -0.11 
+0.18. Execution time, 3/18:08:37.

0.11 plus 0,18. Execution time 3/18:08:37. 

CAPCOM Roger, we have the data. Hoot, thanks a lot. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston, be advised you do not have to 

do any cabin maintenance this morning, your environment looks 
gocd. We show your cabin at 10.31. 

SPACECRAFT Okay, I guess we tricked you, John. We did that 
first thing when we got this morning. We got up and the cabin 
was 10.1. And so we did a N2 repress, because we had — I'm just 
calling it up now, we had a PP02 of 2.78, I guess was our number, 
so we repressed using N2 up to 10.4. 

CAPCOM Roger, good show Hoot, EECOM's smiling down here. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston. In order to maximize our Ku 

coverage this morning before we go EVA, we would like you, if 
it's agreeable with you, to go to a tail forward attitude instead 
of the nose forward and we can do that by selecting an omicron of 
zero. 

SPACECRAFT Okay, that's, is that pre EVA John, that you want 
to do that? 

CAPCOM We want you to do that now. In other words, select 

an omicron of zero and then reinitiate the track to get us into a 
tail forward attitude but we'll get out of it prior to going EVA. 
And we need you to take the encryption to bypass. We're handing 
over back to TDRS. 

SPACECRAFT Okay, I understand John, omicron zero, encryption 
going off. 

CAPCOM Challenger, Houston, we're going LOS, see you at 

Yarragadee at 18 plus 57. 

SPACECRAFT Okay. 

PAO This is Mission Control HouFton, we're LOS 

presently, pick up again through Yarragadee in 7 and a half 
minutes. Right now the Flight Director, Randy Stone, is getting 
the weather briefing, the substance of which is that weather is 
good throughout all the main landings in the United States — 
landing sites for deorbit opportunities today with the possible 
exception of Kennedy Space Center, which has some low level 
turbulence. Postsleep activity dominating the early morning

crew activity plan onboard the Challenger this morning which has 
to do with the stowage of gear, preparation for the day's 
activities by gaining the access to the principal documents for 
today's use, the EVA checklist, EVA prep materials, breakfast, 
and configuring the cabin lighting and windows for the day's 
activities. Mission Elapsed Time is 3 days, 18 hours, 50 
minutes, this is Mission Control, Houston. 

CAPCOM Challenger, Houston is with you through Yarragadee 

for 6 and a half minutes. Challenger, Houston is with you over 
Yarragadee for another 5 minute , 

SPACECRAFT Roger, Houston, you're coming in broken, 

CAPCOM Roger, understand, coming in broken, and so is your 

return line. 



SPACECRAFT We're on the edge of coverage. 

CAPCOM Roger that. Challenger, Houston. We are 1 minute 

to LOS Orroral, we will see you TDRS at 19 plus 28. 

SPACECRAFT Roger, John, we just got a great view of Australia. 
CAPCOM Roger, that.

CAPCOM - - plus 28. 

SPACECRAFT Roger, John. We just got a great view of 
Australia. 

CAPCOM Roger that. 

PA0 This is Mission Control, Houston. We're advised by 

the Goddard Tracking network that the ground station at Dakar is 
not going to support this pass. At approximately MET of 3 days, 
18 hr, 37 min, Dakar experienced a power dropout. There were 
some surges on its primary power sources. They went to backup 
power, and as of right now, they still haven't recovered and 
we're advised not to expect support from Dakar during the current 
pass. Challenger now over the mid south Pacific Ocean on orbit - 
- ascending node of orbit 61 at Mission Elapsed Time, 3 days, 19 
hr, 20 min. And we'll acquire through the TDRS system in about 7 
min. This is Mission Control, Houston. 

CAPCOM Challenger, Houston is with you through TDRS. 

SPACECRAFT Roger, Houston. 

PA0 This is Mission Control, Houston. We're taking 

data through the TDRS system at Mission Elapsed Time, 3 days, 19 
hr, 30 min, and it looks as though Mission Specialist, Bruce 
McCandless, has got the EVA suits of the Extravehicular Mobility 
Units up and running. The batteries have been charged and topped 
off, and probably within the next 30 min, McCandless and Stewart 
will begin donning the EMU's in preparation for today's EVA. 
Mission Elapsed Time, 3 days, 19 hr, 31 min, this is Mission 
Control, Houston. 

CAPCOM Challenger, Houston. If somebody's free, we have a 

request for you. 

SPACECRAFT Okay. Go ahead, John. 

CAPCOM Roger, Hoot. Two options, your call. If somebody 

would like to read down the MMU temp data to us off of SPEC 77, 
we'll take it that way, or you can load some new TFL ' s for us, 
and I'll give you the numbers, and we'll get the data 
ourselves. Your call. 

SPACECRAFT Okay. If you're ready to copy, John, I can give 
you the MMU values and temperatures. 

CAPCOM Ready to copy, Vance. 

SPACECRAFT And this will be port starboard, port starborad, 
port starboard all the way down.

CAPCOM Roger. We have all the data. Thanks, Vance. 

SPACECRAFT Houston, Challenger. Radio check. 

CAPCOM Roger. Loud and clear, Bruce. You're coming 

through a little broken, but loud and clear. 

PAO This is Mission Control, Houston. Commander Vance 

Brand read down those temperatures on the two Extravehicular 
Mobility Units, temperature and nitrogen pressures, and the EVA 
systems officer here in the control center pronounced those as 
good numbers, well within tolerances, and consistent with 
readings that have been received right along this mission. It's 
3 days, 19 hr, 39 min Mission Elapsed Time, and we still have 
another 45 min remaining on this TDRS pass. This is Mission 
Control, Houston. 

SPACECRAFT Houston, this is Challenger. Over. 
CAPCOM Roger. Go ahead, Bruce. iiOud and clear. 

SPACECRAFT (Garble)

SPACECRAFT Houston, this is Challenger, over. 

CAPCOM Roger, go ahead Bruce, loud and clear. 

SPACECRAFT Roger, John, Houston. A question regarding the 
mass spec EVA repair. Looking at the drawing and looking out the 
window here, we assume that what you're showing us is accessible 
from the starboard side of the Orbilet looking toward the mass 
spec, is that correct? 

CAPCOM That's affirmative, Bruce. 

PAO This is Mission Control, Houston at 3 days 19 hours 

43 minutes Mission Elapsed Time. Bruce McCandless' call having 
to do with the mass spectrometer located in the payload bay. The 
teleprinter message this morning advised the crew that that would 
be one of their contingency activities during the EVA. The mass 
— the problem with the mass spec is thought to be a micro- 
switch that's not opening and the remedy by the EVA astronauts 
will be to insert a probe into an opening between the micro- 
switch body and the switch cam lever and to pry on that mechanism 
to cause a lever to deform and activate. McCandless' question 
had to do with access to that, that device. 37 minutes remaining 
in this pass, this is Mission Control, Houston. 

SPACECRAFT Houston, this is Challenger, over. 

CAPCOM Roger, go ahead, Bruce. 

SPACECRAFT Roger, (garble) on that question on which side the 
microswitch is on. We've got a couple of lights on here in the 
payload bay and the binoculars on so we can see it. I 
respectfully submit that instead of the probe and the hammer, it 
might be more appropriate if I just took a large jeweler's screw 
driver out there with me to do the bending operation. Over. 

CAPCOM Roger, stand by Bruce and we'll come back with our 

solution of what we think of your suggestion. 

SPACECRAFT Okay, what we're looking at, for the guys in the 
SPAS backroom, is from out of the (garble) which is on the 
starboard side of the Orbiter. We're looking back and we can see 
a (garble) gray metallic, looks like anodized aluminum or 
something like that, or maybe they're beryl titanium, support 
struts. Coming out of the middle, or at the pivot point on the 
starboard support leg, is something that looks like maybe a 
torque motor or a shaft position encoder or something like that. 
It's a silvery can about an inch and a half in diameter and about 
an inch deep, and above that and attached to or mounted very 
close to the gray support leg is a package about an 1/8 of an 
inch thick, 3/4 of an inch in the Orbiter's Z direction. There 



STS-41-B AIR/GROUND TRANSCRIPT tl83j 038:08:41 2/7/84 PAGE 2 



are some wires coming out of it, and we take that to be the 
micro- switch. Over. 

CAPCOM You have it, Bruce. 

SPACECRAFT Okay, thank you. I'm going to give this copier 
back to Bob, I having all sorts of trouble with my comm, so when 
you come back with that answer for me, be sure to ask somebody to 
relay or ask them to get me on another comm here. Over. 

CAPCOM Roger, that, and, Bruce, just for your information 

that's a real good interpretation you made of that picture we had 
to send up. 

SPACECRAFT Okay, and what you really want me to do is to 
spring the release the microswitch so that it has a rotation less 
travel from the cam to open the circuit, right? 

CAPCOM That's affirmative Bruce. 

SPACECRAFT Okay, thank you. 

CAPCOM Challenger, Houston. Be advised in about 5 

minutes, we're going to be doing our troubleshooting check of the 
mass spec. 

SPACECRAFT Okay, give us a call, because I'd like to watch it 
work. 

CAPCOM Roger, Bruce. The command is set for 20 plus 00, 

that's in four and a half minutes. Challenger, Houston. Bruce, 
I have an update on that swivelling... 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT tl84j 038:08:55 2/7/84 PAGE I 



CAPCOM Roger, Bruce the command is set for 20 plus 00, 

that's in four and a half minutes. Challenger, Houston, Bruce I 
have an update on that swiveling motion when you're ready, 



SPACECRAFT Go ahead John. 



CAPCOM Roger, Bruce. Payloads has informed us that we 

expect the swiveling should start at 20 plus 02 plus 40 and we 
believe that it'll go ahead and point in the X axis and then 
return to the Z axis if the microswitch is still broken. 



SPACECRAFT Okay. 



SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead. 

SPACECRAFT John, the swivel happened a little earlier than we 
were expecting it to, it went at about 20 and 30 seconds or so 
and so Bruce wasn't up here when it went. 

CAPCOM Roger, understand. 

SPACECRAFT And John, we seem to be getting a, the dual 
broadcast out of you again. 

CAPCOM Okay, how is it now? 

SPACECRAFT Yes, that's great now, thanks John. 

CAPCOM Challenger, Houston, we're on the call right now 

and we're about 30 seconds to. .. Challenger , Houston, we are on 
the Dakar UHF right now, we may not pick you up TDRS, if we 
don't, we'll see you next at Yarragadee at 20 plus 32. 

SPACECRAFT Okay, John, we copy, with you in Australia. 

PAO This is Mission Control, Houston. The ground 

control officer reports that pretty severe thunderstorms in 
Austrailia have rendered the Yarragadee and Orroral ground 
stations inoperative and unlikely that we will be able to acquire 
voice through Yarragadee or voice and data through Orroral. 

CAPCOM Challenger, Houston, be advised that we will 

probably not have contact with you on this pass at Yarragadee and 
Orroral Valley. We have had some ground station problems. 

SPACECRAFT Okay, John, we copy that, we won't see you in 
Australia. 



CAPCOM Challenger, Houston, if Bruce is available, 

whenever Bruce can get to the window, if you will let us know, we 



STS-41-B AIR/GROUND TRANSCRIPT t!84j 038:08:55 2/7/84 PAGE 2 



will then send a command to swivel the mass spec. 
SPACECRAFT Stand by John. 

CAPCOM Roger, no rush. When he gets there, just give us a 

call and then we'll send the command and we have about 11 minutes 
before LOS TDRS. 

SPACECRAFT John, we're too busy now, so we'll just let it go. 
CAPCOM Roger, we understand, Vance. 

PAO This is Mission Control, Houston. The ground 

control officer advises that despite the storms in Australia, 
Yarragadee and Orroral have recovered sufficiently to provide 
voice communication during the next pass, but that the wide band 
data in Orroral is still inoperative so while we will have voice 
through Orroral, we'll get no data, and Yarragadee of course is a 
UHF voice only. Mission Elapsed Time, 3 days 20 hours 13 
minutes, this is Mission Control, Houston. 

CAPCOM Challenger, Houston, we're going to be going LOS 

here TDRS in a minute and a half. We think Yarragadee and 
Orroral may be up, if not, we'll see you TDRS at 21 plus 05, 
hopefully at Yarragadee in about 10 minutes. 

SPACECRAFT Okay, John, we'll listen for you. 

PAO This is Mission Control, Houston. We're out of 

range of TDRS, we will acquire through Yarragadee in 8 minutes.

SPACECRAFT Roger, Houston. We copy you loud and clear, and 
we're into the RMS deploy, and we're working step 4. 

CAPCOM Copy that, Ron, and for the EVA guys, we got a good 

biomed check as you went over the hill at Orroral. 



SPACECRAFT Okay. Great. 



CAPCOM And also, a question on the heat pipe. Did you 

guys have to put the power back on, or was it on? 

SPACECRAFT Don't understand your question, Jerry. 

CAPCOM Okay, Ron. We made a call in the blind at 

Yarragadee requesting that the heat pipe power be cycled back to 
on. We saw an indication on the ground that it was off, and we 
were just wondering if you had to do that, or if it was a false 
indication on the ground. 

SPACECRAFT Okay, Jerry, we never heard that call. I wasn't 
aware that the power was off. I'll check and see. 

CAPCOM Okay. It looks good to us now, so it must have 

been a false indication earlier. Thank you, Ron. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston. We'll be sending you a new 

state vector, and I have your Ku times on EVA checklist, flight 
step 11-1 when you're ready to copy them. 

SPACECRAFT Okay. Stand by just a second, Jerry. 

CAPCOM Roger. 

SPACECRAFT Okay. I've got that page. I'm ready to copy. 

CAPCOM Okay, Hoot. I will give them to you by rev number, 

MET, and PET. First, rev 64, MET 23:08, a PET of minus 2 min. 
rev 65, 00:43 plus 01:33. Rev 66, MET 02:19, PET plus 03:09.

didn't get the second two. The first one, MET 23:08, rev 64, 
that was minus 2 min. The next one, rev 65, 00:43, and I think I 
copied plus 66 min, and then give me the other two again.

SPACECRAFT Okay, PET on rev 65, 1 hour, 33. 

CAPCOM That's affirmative and, Hooter, can you tell us 

what the comm problem appears to be on your end? 

SPACECRAFT What comm problem are you referring to, Jerry? 

CAPCOM I'm sorry, Hooter. It just seems that you're 

having a hard time copying me, so I figured you had some kind of 
comm problem. 

SPACECRAFT No, we had good comm, I just mixed it up on some of 
the numbers. 

CAPCOM Okay, copy that, thank you. 

SPACECRAFT John. (garble), (garble). 
SPACECRAFT Okay.. 

SPACECRAFT I don't hear you, Vance. You have to transmit. 
SPACECRAFT Okay, your EV on? 
SPACECRAFT EV1, EV2 , how do you hear? 

SPACECRAFT I hear loud and clear. Yes, I heard you now. 
SPACECRAFT Very good. 

SPACECRAFT And, it's the, you know the to the narrow side to 
the narrow side. 

SPACECRAFT Now it's up. It comes down from the top. I saw it 
up there a minute ago. 

SPACECRAFT Good copy there, definitely when I went in. And 
that one seemed to be a little hard, you have to push all the way 
and make sure the fingers clamp in on the side to lock. Yes, 
it's stiff netting. 

SPACECRAFT Houston, this is EVl, you reading? Over. 

CAPCOM Roger Bruce, we're reading your loud and clear. 

How me? 



STS-41-B AIR/GROUND TRANSCRIPT tl87j 038:10:10 2/7/84 PAGE 2 



SPACECRAFT Okay. I should be sending biomed now and Bob will 
be sending it in a couple of seconds. You can ask him to check. 

CAPCOM Roger, copy that Bruce. We got good biomed as you 

left Yarragadee, Orroral Valley, rather. 

SPACECRAFT Okay, so I understand we're both go on biomed. 
CAPCOM That's affirmative, Bruce. 

SPACECRAFT Okay. 

SPACECRAFT And Jerry, this is EVP., how do you copy? 

CAPCOM Roger Bob, I got you loud and clear, also. We got 

a little bit of background static on the downlink but 
everything's good. 

SPACECRAFT Okay. 

SPACECRAFT And the (garble) locked in also, Vance. 

SPACECRAFT Well, MET is go. Now here's the one where you call 
Ron and Hoot down to help also. We'll see. I'm just joking. 
They claim that the easiest way to do it is to lift the front up 
and match the, see the white lines on the ring? There some white 
lines on the waist also. You see those ... Just hold or ask Bob 
to hold that and try to rock the back up. Okay, but you're free 
to do it any way you want, of course. 

SPACECRAFT Okay, I'm pulling. 

SPACECRAFT Amazing!

SPACECRAFT Amazing. 
SPACECRAFT Okay. 

SPACECRAFT (garble) we decided the (garble) . 

SPACECRAFT There's a little strip that comes over (garble). 
And a motion back out of the cabin (garble) cargo bay. I think 
it's the only thing that stays in here with us. I'm not sure 
what that does. 

SPACECRAFT Alright. 

SPACECRAFT Those little brown straps, little brown straps. 

SPACECRAFT Hey, Jerry you are in good TV viewing position and 
we've got some good Cinema 360 footage. 

CAPCOM Okay, Ron, I don't copy all of that. I understand 

t'ne arm is positioned and you did get some good 3, cimena 360 
footage of it. And for the EVA guys, we're still hearing their 
conversations in the airlock, if they want to reconfigure. 

SPACECRAFT I don't think they will probably stay in this 

configuration. Since now we got comm established, let's not lose 
it. 

CAPCOM Okay, Bruce, the only advisory then is that the 

other guys onboard will have to try to work between your 
discussions over the cameras. 

SPACECRAFT Okay, John, we copy that. 

SPACECRAFT (garble) Vance. 

SPACECRAFT (garble) make sure you (garble) 

SPACECRAFT Houston, Challenger. 

SPACECRAFT Lock it up. I'll get my hand in later. 

SPACECRAFT (garble) let me try it again. Looks like there's a 
little, okay, just, just belt it in again. Yes, that's better. 



END OF TAPE 



STS-41-R AIR/GROUND TRANSCRIPT tl89j 038:10:24 2/7/84 PAGE 1 

SPACECRAFT Feels like it has a little. Okay just put your 

... belt it in again. Yeah, that's better. Hold off on that til 
we get to the check lock. (Garble) was outside in the biomed 
kit. Biomed is stuck on the galley over on (garble) . Okay, 
close her up. Better lock, or engage, first. First you do. 
Beautiful. Leave it open til we get to the check lock. 
Flashlight battery? It's the one that appears first. You 
flopping that battery around too much? (Garble) . (Garble) . 
(Garble) he was flying a little bit. That's going to do it. 
Just a little more pressure. Yes, that's good like that. 

PA0 This is Mission Control, Houston. The EVA crewmen 

are suited and in the airlock, and as an effect of that 
configuration, there's going to be a lot of sizzle and noise on 
the line and, unfortunately, it's something we're just going to 
have to live with until the EVA begins. Mission Elapsed Time is 
3 days, 21 hr, 29 min. Have another 30 min on this TDRS pass. 

SPACECRAFT This is (garble) good.

SPACECRAFT They're securing good. (Garble) could you speak a 
little louder Vance. 

SPACECRAFT Okay. 

SPACECRAFT Okay and, Bob, why don't you turn yours back off 
for a second, let me get mine cn anJ then. (garble) now, you 
don't have much clearance on the ce > Ling with that TV on. But 
the thing has got to come all the way down on the back of my head 
first to clear my eyeglasses. So the back has to come down first 
and then the front. Why don't you reach up there and pull on 
that, we can swivel it 90. There we go, that will help. 

SPACECRAFT May have been some of that 180. 

SPACECRAFT Yes. Yes, that's where they want it. Okay. Good. 

SPACECRAFT Bruce, are you ready? 

SPACECRAFT No, we'll wait, but I'm reading you. 

SPACECRAFT Okay, 02 actuator IV. 

SPACECRAFT In work. Okay, it's IV. 

SPACECRAFT First, valve 2 closed and locked. 

SPACECRAFT Okay, its closed and locked. 

SPACECRAFT Okay. 

SPACECRAFT S I can get Bob now. Here. 

PAO This is Mission Control Houston. The power supply 

amperage readings here in the control center indicate that 
Mission Specialist Bruce McCandless has gotten into his EVA suit, 
the extravehicular mobility unit, and has secured it and has the 
fans turned on and we're getting some good data, some good 
readings on that. Now as I'm reporting that, I see EMU number 2, 
Bob Stewart's is also coming online so it appears that the two 
crewmen are in their EMU's, they're powered up and beginning the 
prebreathe. It looks like we're - .out 30 minutes ahead of the 
timeline, so conceivably then the EVA will begin 30 minutes 
earlier than predicted and earlier than shows in the timeline. 
And again, so far all the current, voltage, and temperature 
readings in the EMU's are completely nominal and all look very 
good. 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT tl91j 0 38:10:34 2/7/84 PAGE 1 

PAO - - for all the current, voltage, and temperature 

readings in the EMU's are completely nominal, and they all look 
very good. 

SPACECRAFT Cover your — the springs that hold that. This 
cuff checklist is coming apart. The spring needs to be slid back 
into the middle. See, that set screw that's supposed to hold it 
there? That's the one they didn't lock tight. You just have to 
to slide the spring part. You'll unloosen that little screw, 
Vance, then slide the spring, then tighten the screw. I'll tell 
you what, let's press on with getting the prebreathe going, and 
then we can work on that. I can hardly hear you. Yeah, okay. 
Can't hear you. Just try another unit, you're not transmitting 
at all. I can hear him out there. We can hear you out there, 
Vance, very weakly, but we can hear you. As long as you stay out 
there. Vance, you could get a hardline and hook up into this CCD* 
in here - - if that's what you're on. Or we could go hardline 
too. Why don't we try hardline? Okay that's not either. 
Good. Okay. That was a big help. Okay, if you're still hearing 
nie now. Okay. So, wrist rings are covered, waist rings are 
covered, time mode, EV1SA, well, hardlines, we'll have to get it 
back. (Garble). Got bad static. Okay, check power SCU. Okay, 
if I'm out here, I think it's okay. Deck fan on. The comm

SPACECRAFT ...4.2 to 4.4. 

PAO ...on the mobility units and checks look awfully 

good, doesn't look like there's any loss of pressure in the 
suits. 

SPACECRAFT Okay and, Bob, what did you say your pressure 
was? Okay, sounds good. Go to IV and then I'll time you for a 
minute. Start. 

CAPCOM Challenger, Houston, for Ron. 

SPACECRAFT Go ahead John. 

CAPCOM Ron, we'd like to get some Ku TV here. If you can 

ensure that the RMS wrist camera is selected, we'd like to 
operate the bay cameras for awhile. 

SPACECRAFT Okay, we'll configure that. Okay. Okay, Houston, 
Challenger, we got the cameras up and they're all yours. We had 
aimed the elbow camera earlier if you want to look at that one. 

CAPCOM Okay, we wanted to see what view we were getting 

out of the wrist camera and I'll see if INCO's happy with that, 
we may ask you to go back to elbow. 

SPACECRAFT Okay, let us know if you want it. 

PAO This is Mission Control Houston, we're looking out 

the end effector camera right now to see if there's any debris in 
the lens from having used that camera to watch the perigee kick 
motor from PALAPA during the firing yesterday. 

CAPCOM And Challenger, Houston, we'd like to go back to 

the elbow camera now, please. 

PAO And this elbow camera will be the color picture. 

SPACECRAFT (garble) elbow camera. 
CAPCOM Thank you. 

PAO Well, that's not it, obviously, that's here in the 

control center. And there's the elbow camera, color camera, 
looking down into the payload bay. That little flash of color in 
the lower left quadrant of the picture, right at the foot of the 
RMS, that's the mass spectrometer. Interestingly, from the tops 
of the canisters on the — the tops of the get-away special 
cannisters on the starboard side of the payload bay show 



STS-41-B AIR/GROUND TRANSCRIPT tl92j 038:10:40 2/7/84 PAGE 2 

reflections of the clouds as the Earth — as the Orbiter passes 
over the Earth with the payload bay toward the Earth. You can 
barely see the blue sky and the cloud cover reflected in those 
canisters tops. This view from the alpha camera. The port 
forward — port side forward bulkhead camera looking back toward 
the OMS pods and the vertical stabilizer with the closed 
sunshields from the Westar payloads assist module in the 
foreground. And dangling down from the top of the picture is the 
end effector from the remote manipulator arm. This is Mission 
Control, Houston. This is the delta camera, the stuck color 
wheel obscuring the upper half of the image of this camera and, 
of course, it's a black and white picture because that cover 
wheel refuses to rotate. There's alpha camera once again showing 
the Earth. The Earth's at the top of the screen here, the 
Orbiter just now over the continent of Africa and directly over 
Zambia at this time. Trajectory will carry it part of — to 
Zimbabwe, Mozambique, and across to Madagascar. 

CAPCOM Challenger, Houston. We're starting to drop in and 

out on TDRS, we're 4 and a half minutes to LOS, Yarragadee is

CAPCOM Challenger, Houston, we're starting to drop in and 

out on TDRS, we're 4 and a half minutes to LOS . Yarragadee is 
next at 22 07. 

SPACECRAFT Roger, and we're purging right now. 

CAPCOM Roger, copy thank you. Challenger, Houston, we're 

about a minute LOS TDRS, we may not get you at Yarragadee, Hawaii 
at 22 34. And because of the purge operations on the suits, we 
see you're getting PP02 messages. Recommend channel 4 be set 
to 10.8, channel 34 to 3.2 and channel 44 to 3.1. Over. 

SPACECRAFT Okay, John, we were watching that and we thought 
that that was due to the purge also. We'll change 4 to 10.8, 34 
to 3.2, 44 to 3.1. 

CAPCOM Roger that, see you probably at 22 34. We'll try 

at Yarragadee also. 

SPACECRAFT Okay, we'll see you there, John. 

PAO This is Mission Control, Houston, at Mission 

Elapsed Time 3 days 21 hours 59 minutes. We propose to cancel 
the scheduled 9:15 change-of-shi f t briefing with flight director 
Randy Stone. Stone was on console for only about 3 and a half 
hours this morning before being relieved by the EVA flight 
director, Johri Cox, so inasmuch as he had a brief and uneventful 
shift, and in addition to that the press conference would fall in 
the middle of the EVA, which certainly doesn't seem to make a lot 
of sense to distract media attention from that event. We have 
proposed to cancel that scheduled 9:15 press conference. We'll 
pick up a signal again through Yarragadee on orbit 63 in about 7 
minutes at Mission Elapsed Time 3 days 22 hours. This is Mission 
Control Houston. This is Mission Control Houston. No voice 
through that Yarragadee pass, we'll acquire again in 17 minutes 
through Hawaii. Prebreathe has begun, the crew went into 
prebreathe about 30 minutes early. There are no plans to 
commence the EVA early, however, this will really constitute a 
prebreathe period of 30 minutes longer than originally 
timelined. But the EVA crew did move gingerly along its timeline 
and is ahead of schedule but the EVA will begin on time. Mission 
Elapsed Time is 3 days 22 hours 17 minutes, we're 16 minutes from 
AOS Hawaii on the 63rd orbit of the Earth. This is Mission 
Control Houston. This is Mission Control Houston, we're a minute 
and a half away from acquisition of signal through Hawaii, about 
a 6 minute pass over that ground station. Flight director John 
Cox just instructed his control team to make a last hard look at 
their systems information during this data take to assure that 
everyone is a good for EVA. Egress nominally should occur in 
about 35 minutes, 35 to 40 minutes and we are less than a minute 
away from acquisition of signal. At Mission Elapsed Time 3 days 
22 hours 33 minutes, this is Mission Control Houston. 



STS-41-B AIR/GROUND TRANSCRIPT tl93j 038:10:50 2/7/84 PAGE 2

minute between coverage from Hawaii, then to TDRS. Vance Brand 
reporting the normal EVA prep, and reported that the crew began 
prebreathe at a Mission Elapsed Time of 3 days, 21 hr, 55 min. 
We're less than a half an hour from egress, and that would give 
the EVA crewmen around 35 min prebreathe beyond the nominal. The 
plan was to have 40 min prebreathe. Looks like the actual will 
be nearer 75 to 80 min, which - - 



END OF TAPE

PAO ...will give the EVA crewmen around 35 minutes 

prebreath beyond the nominal. The plan was to have 40 minutes 
prebreathe. Looks like like the actual will be near 75 to 80 
minutes which is of course prudent and futher reduces the chance 
of the onset of bends. We'll have AOS in about 20 seconds

PAO This is Mission Control Houston, we're out of 

range of the TDRS , McCandless and Stewart are clearly in the 
payload bay and initiating some of the work objectives from the 
crew activity plan at, it was clear that Bruce McCandless was 
checking the pressure levels in the MMU's and Bob Stewart had 
been over in the vicinity of the delta camera, checking it for 
power supply and checking its range of motion. We'll acquire

in 16 min. EVA sysems officer reporting that the EVA crew is 
about 10 min behind the timeline. They're still involved in the 
MMU preps and that Bruce McCandless has yet to free the MMU from 
its mounting and begin a slight test of that system. Orbiter* s 
position at this time is flight with its tail to the Earth, 40 
deg off vertical. The payload bay is opposite the velocity 
vector, meaning that the Orbiter is essentially flying with the 
underside, the thermal protection system into the velocity 
vector. At Mission Elapsed Time, 3 days, 23 hr, 53 min, this is 
Mission Control, Houston. 

PAO This is Mission Control, Houston. We're about a 

minute and a half away from acquisition of signal through Hawaii 
on orbit 65. Bruce McCandless should be completing the MMU 
donning and checkout procedure as outlined in his activity 
plan. That, essentially, is verifying that the tethers are clear 
and backing into the MMU so that the MMU and PLSS latches enagage 
with the MMU constraint.

the MMU constraint and pulling down the rings which have the 
effect of freeing those latches. Just to verify that the, it's 
possible to secure and release from that system. He will then 
attach a lap belt, configure valves in their power system's

away from it. 



SPACECRAFT 



Looks great, Bruce. 



SPACECRAFT Thank you, I'm trying to see what sort of land mass 
that is we're coming up on. It looks like Florida, it is 
Florida, it's the Cape. 



Yeah, you're on the state side, Bruce, 
Oh, I got to see if I can get a picture of this. 
You're not too far from Houston as a matter of

CAPCOM Roger, we got a little bit of it earlier, Vance. 

Some super views. 

SPACECRAFT I think when you get out further Bruce, we'll be 
able to see the whole ship, right now we can see a corner of it. 

SPACECRAFT Okay. 

SPACECRAFT Look out there, Bruce. 

SPACECRAFT It's nice, the sun just came into my eyes, that's a 
little bright, but, not a big deal. Going over the Florida Keys, 
sort of. Okay, 1900 on the left, 1800 on the right. Let's see 
how this state of the art ranging device is going to work. Well, 
I show myself about 80 feet out, something like that. I could go 
faster but why rush it. 

PAO McCandless at a distance of about 80 feet. 

SPACECRAFT Found me on the TV ranger yet? 
SPACECRAFT Not yet. 

PAO He'll be going about twice that far out on this 

exercise. 

SPACECRAFT (garble) above the ship. 

SPACECRAFT Yeah, that's what I'm trying to do, verifying that 
it's working out. 

p AO McCandless in his man maneuvering unit, constitute 

a separate spacecraft of there own now. 

SPACECRAFT Well, you may get the name of the world's fastest 
human being, going along there at 4 miles a second, Bruce. 

SPACECRAFT The record will only stand I guess, for the next 
hour or so. 

SPACECRAFT Just past over Florida and Cuba. 

SPACECRAFT Well I guess to break it Robert, is going to have 
to go 10 percent faster. 

SPACECRAFT (Garble) like I've got enough (garble). 

SPACECRAFT I'm showing myself at about 95 feet right 

now. Maybe right at a 100. Got that ranger going yet. 

SPACECRAFT We've got you at 123 feet at about .3 feet per 
second. 



STS-41-B AIR/GROUND TRANSCRIPT t208j 038:13:30 2/7/84 PAGE 2 

SPACECRAFT Okay that sounds about right. We always seem to 
have about a 25 foot difference between what I read and what the 
simulator up at Martin with (garble) and all those guys came up 
with. Point 3, okay. Give it a little more - - 

SPACECRAFT (garble) what are you. 

SPACECRAFT Houston Challenger 

CAPCOM Go ahead Challenger. 

SPACECRAFT Why don't you go ahead and take the cameras, I'm 
going to work the lasers, on camera's B and C. 

CAPCOM Copy, we'll take the other cameras, you've got 

baker and charlie, Ron. 

SPACECRAFT Okay, 145 feet, Bruce, at well a little noisy, 
around .3 yet. 

SPACECRAFT Okay, why don't I try to come to a stop here. 

SPACECRAFT Yeah, matter of fact you just hit 150 feet, so 
you'd probably better stop. 

SPACECRAFT Yeah, I should be just about stopped now. And I'm 

reading 125, so yeab. You should have a ranger at just about 0 
now. 

SPACECRAFT We're seeing about .2. 

SPACECRAFT Point 2? Okay. Okay, and I'll come on back in. 

SPACECRAFT Great. 

PAO MMU has a - 

SPACECRAFT (Garble) it's real solid on stability. 

SPACECRAFT Yeah, it really is and so far the only surprise is 
that, like I say, when I put on a +X for a couple of seconds, I 
feel a sort - -

STS-41-B AIR/GROUND TRANSCRIPT t209j 038:13:35 2/7/84 PAGE 1 
SPACECRAFT Real solid on stability. 

SPACECRAFT Yes, it really is and so far the only surprise is 
that, like I say, when I put on a fX for a couple of seconds, I 
feel a sort of rumbling, rattling which I assume is interaction 
between the EMU and the MMU, but we hadn't expected it. 

PAO MMU has 24 nitrogen powered thrusters. McCandless 

will begin returning to the spacecraft now. 

SPACECRAFT Well, whoever it is that buiit these visuals did a 
great job. 

SPACECRAFT Ok, .140 feet. 

SPACECRAFT I perceive myself to be closing now, a couple of 
tenths of a foot per second maybe. 

SPACECRAFT Ok, closing at, well, we really can't tell how fast 
you're closing, it's jumping around a little bit, but you're 
coming in, you're about 120 feet out. 

SPACECRAFT Good . 

SPACECRAFT And we're not picking you up on the radar for some 
reason, very well. We can't seem to track. 

SPACECRAFT Well, I may be in a little bit closer - during the 
man mode and low power, and all that stuff? 

SPACECRAFT Yes. 

SPACECRAFT Maybe I should nave eaten some of those cans for 
breakfast unstead of just the food - - 

SPACECRAFT Yes, you're not reflective enough. And Bruce, is 
your EMU camera still on? 

SPACECRAFT Yes Sir. 

SPACECRAFT Somehow we lost (garble) . 

SPACECRAFT Bruce, are you going to take a picture of us? 

SPACECRAFT Ye% I am, but it's joing to better on the next 
one, cause the sun angle is not all that great right now. 

SPACECRAFT (Garble) this time and the next time. 

SPACECRAFT Well, I've taken about 5.

that camera. Okay say those numbers again? 

SPACECRAFT 1800 A, 1600 B. 

SPACECRAFT Okay. 

Are you going to want the windows washed or 
while I'm up here. 

We want you to get out and back before sunset

while you're here we'll just read the 
Bruce. 

you go. Okay, here we go. Hey, you know what 
chatter ing in plus or minus X. I don't know 
attitude roll logic suppressing the thrusters 



;on, you catching all this? 

Challenger, we're still here. No TV but 

Question for Bruce, is the chatter between 
is it in the MHO itself? 

it feels like the X thrusters are chattering 
staying on continuously. 

copy that. 

Vance, got another problem down here with the - 
got tool boards can't seem to get them in. 



you're cutting out again real bad but 
having a problem with the tool board Bob. 



That's affirm. They won't go into the slots. 
Houston, copy that. 



CAfCOM Roger, Vance. Just one query, has Bob rotated the 

locks for the tool boards horizontal such that he can insert 
them? 



SPACECRAFT That's affirm, Jerry. 



STS-41-B AIR/GROUND TRANSCRIPT t210j 038:13:41 2/7/84 PAGE 2 

CAPCOM Okay copy that, Bob. Can you give us any further 

elaboration on the problem? 

SPACECRAFT No further elaboration. Trying to insert the tool 
boards on the top slots. It won't go. 

CAPCOM Roger, we copy that Bob. 

SPACECRAFT You know this is really beautiful out here. 
SPACECRAFT One second. 

SPACECRAFT I'm getting a nice sun angle and everything. What 
do you got for an opening rate on me? About a quarter a foot per 
second? 

SPACECRAFT We'll have to wait a little while until we get a 
good angle on you there, Bruce. We're estimating somewhere 
around 3 tenths. 

SPACECRAFT Jerry, I got one of them in but I regulated back 
and forth. 

CAPCOM Okay, copy that, Bob. 

CAPCOM Challenger, Houston for Bob. 

SPACECRAFT Okay, you're maybe 5 feet from the C camera. 

SPACECRAFT Okay. 

SPACECRAFT Go ahead, Jerry. 

CAPCOM Bob, suggest you try inserting the bottom of the 

tool board first and see if that works any better. 

SPACECRAFT Well, it never has gone in that way but I'll try 
it. It goes in that way and come out. Okay, they're both in. 
The one that was difficult (garble) it in the machine a little 
bit. Looks like it's got the pipes scraped and a little bit of 
metal cut (garble) enough metal cut. 

CAPCOM Okay, copy that Bob. Might suggest swapping boards 

side for side and see if that wc 

SPACECRAFT They're both in now. 

CAPCOM Okay copy that. Sorry. And for Ron - -

SPACECRAFT .5 feet per second. 

SPACECRAFT Okay. Oh, this is superb. 

SPACECRAFT 175 feet. 

SPACECRAFT I'm reading 150, so I agree with 175. Do you show 

about a 1/2 a feet per second opening? 

SPACECRAFT Yes, it's jumping between about .3 and .8 so 
somewhere in the middle of that. 

SPACECRAFT I got a real good look at the main engines now. 

SPACECRAFT 204 feet. 

SPACECRAFT (garble) And to think that this thing was sitting 

on the launch pad just a few days ago. 

SPACECRAFT Yes, it's a marvelous machine. 

SPACECRAFT You know, hey Vance? 

SPACECRAFT Go ahead. 

SPACECRAFT This is, the view you get out here is like the 
difference between the view you get flying in a heavy aircraft 
looking out the little windows and flying in a helicopter at mach 
25, or (garble). It's really a beautiful panorama. 

SPACECRAFT Yes, Bruce we have your view of the EMU camera, but 
I'm sure it must be great out there. 



STS-41-B AIR/GROUND TRANSCRIPT t211j 038:13:47 2/7/84 PAGE 2 

SPACECRAFT Okay, well it's aimed down a little bit, what are 
you seeing in the EMU camera? 

SPACECRAFT It's a little distorted here but we can see the 
entire wing span, we can see the from nose to tail of the 
Orbiter. Maybe if you pitched down slightly we'd have it 
centered better. 

SPACECRAFT Okay. Say when. 

SPACECRAFT (garble) a little better. Maybe a little too much 
pitch. Hey, you got the Earth in. That's great. 

SPACECRAFT I'm going to nuke another one of my scientific 
range measurements here. I will correct it and tell you what I 
think it is. Okay I'm, I guess it's about 250. 

SPACECRAFT It's 260, that's pretty close for a device like 
that. 

SPACECRAFT Well, I put a 25 foot windage on it. Here I got 
this EMU turned up full hot, but I'm actually getting a little 
bit chilly out here. And I'm taking pictures with great 
regular ity. 

SPACECRAFT Okay, we have you at out .3 feet per second, 
(garble) 

SPACECRAFT Good comfortable speed.

SPACECRAFT Okay, (garble). I'll do a little at a time. How' 
that, Bob. 

SPACECRAFT More. 

SPACECRAFT Need more? 

SPACECRAFT Hold it right there. 

CAPCOM Challenger Houston, we're going LOS here., in 10 

seconds, Hawaii is next in 6 minutes. What we're following from 
Bob's activity we recommend that he terminate once he gets the 
MFR installed, configured, and press for the MMU. 

SPACECRAFT Okay, we copy, did you get that, Bob? 

SPACECRAFT I got it.

SPACECRAFT Ok, that's it, Bob. 
SPACECRAFT (Garble) it. 

SPACECRAFT Problem, Vcnce, is that with the tool board in 
(garble) 

PAO Astronaut Ron McNair inside the Shuttle manuevering 

the mechanical arm while Astronaut Bob Stewart in the Manipulator 
Foot Restraint will be moved to the area's force input locations, 
be working there at those locations and they'll be evaluating how 
stable and how firm a platform the RMS and MFR combination is. 
Mission Control Houston, 4 days, 1 hour, 43 minutes, Mission 
Elapsed Time. We're a little less than a minute away from 
picking up again over the Hawaii station. Astronaut Bruce 
McCandless in the cargo bay is busy recharging the port Manned 
Manuevering Unit with nitrogen and Astronaut Bob Stewart at the 
Manipulator Foot Restraint mounted on the mechanical arm which is 
being manuevered by Astronaut Ron McNair who is up at the aft 
flight deck. 

CAPCOM Challenger, Houston with you through Hawaii for 7- 

1/2 and we're getting good TV. 

SPACECRAFT Roger, Houston, right at the moment Bob is trying 
to restart the MFR. Bruce is giving him a hand. 

CAPCOM Roger, copy that, Vance. 

SPACECRAFT Jerry, the problem is, trying to hold onto the 

rabbit ears, and it's too slick. 

SPACECRAFT Yes, just hold onto it until Bruce gets there to 
help. 

SPACECRAFT Yes, are you trying to restow it? Yes. Well, put 
it in the RMS. 

SPACECRAFT I'm trying to restow it. 

SPACECRAFT Aren't we going to use it? 

SPACECRAFT I've got to get the (garble) deployed.

SPACECRAFT Here we go. Just a second. Stay back on you side 
there. Do you know what's happened also, it looks like it's 
broken, (garble) maybe. Ok, lets float her in. 

CAPCOM Challenger, Houston, I've got a couple notes for 

you, we'd like to get TV during initial portion of the TDRS. 

SPACECRAFT Could you say again, Jerry, we didn't copy that. 

CAPCOM Ok, Ron, when we come up on TDRS we would like to 

take the Ku control to command and on GNC SPEC 33, we'll need an 
ITEM 2 EXECUTE, verifying that there is no asterisk. That will 
allow us to have TV off of TDRS for a while early in the pass 
until such time that we have to drop it because of the pointing 
angles. 

SPACECRAFT Ok, she's locked in. 

SPACECRAFT Ok, Jerry, we copy that, that's when you come up on 
TDRS. 

CAPCOM That's affirm, as soon as we go LOS here you can do 

that, and also Hoot, one other suggestion, when you try radar 
during Bob's translations, suggest - -

TDRS? 

CAPCOM That's affirm, as soon as we go LOS here, you can 

do that. And also Hoot, one other suggestion, when you try radar 

during Bob's translations, suggest using more auto track with 
manual search, 

SPACECRAFT Okay, Jerry, auto track was the only one that I had 

any luck in at all. I was getting the signal returned in that 
one, but I was getting it any where olse. 

CAPCOM Roger, copy that, thank you. 

SPACECRAFT And let me add, even in auto track, it never did 
establish a track on him, 

CAPCOM Copy. 

SPACECRAFT Okay we're locked back in the APC back here. The 
(garble) is deploy, what next? Okay, you want to recapture it, 
in the extension deploy. 

SPACECRAFT Okay. 

SPACECRAFT Stand by, 3ruce, stand by, Bruce. Okay, Bruce and 
Bob we're ready to go ahead and recapture. 

SPACECRAFT Yeah I'll get out of the way, and let Bruce, 
(garble) - best unit. 

SPACECRAFT And we need yo get you back to the MMU . 

SPACECRAFT Okay. Hey Bob, the configuration of the MMU, is 
you're hooked up to system 1, you're flowing gas, the crossfeed 
valves are open. You're in the middle of a propellant recharge. 

SPACECRAFT Okay. 

SPACECRAFT You need to terminate that, and then go fly. 

SPACECRAFT Thank you (garble) . 

SPACECRAFT Enjoy it, have a ball. 

SPACECRAFT (Garble)

SPACECRAFT No but I'm going to leave the (garble) here with 
you. (Garble) in the trashbag. 

SPACECRAFT Okay. 

PAO Bob Stewart preparing to move over to his MMU, and 

lock into that. 

SPACECRAFT And Bruce, you know the attitude that we're going 
to need that MSR in is going to be with the - parallel to the 
longeron with the handles at the aft. 

SPACECRAFT Well, hang on a minute. (garble) get myself 
tethered here. 

SPACECRAFT Bob, where's the force of evaluation device at? 
SPACECRAFT It's out here. 

SPACECRAFT And Bob, you'll terminate the recharge (garble) 
SPACECRAFT (Garble) What are you saying Hoot? 

SPACECRAFT Okay, when you get ready to hold that guy up there 
to put the grapple fixture in, of course, the MSR is going to 
want to be with the handles to the aft part of the spacecraft. 

SPACECRAFT Why don't you rotate the end affector to 90 
degrees - 

SPACECRAFT Okay, yeah, yeah, Ron could do that. We put it 
back and start it (garble) 

SPACECRAFT Say, Ron. Put it in the end affector mode, and 

come on down and (garble) at the (garble) there to your right. 

SPACECRAFT 90 degrees. I'll put the end affector, you want it 
outboard. 

SPACECRAFT I want to put it right down on top of the -

the Tracking Data Relay Satellite. We may get some television in 
the early part of the TRDS pass thru the use of the Ku-band 
antenna, until about 1/3 or 1/2 of the way thru the pass. We 
lose it due to pointing angles. We're at 4 days, 1 hour, 53

the MFR, would you like to have him do his normal timeline or 
pick up things that Bob would have done. 

CAPCOM Ok, Vance, we proprose that he press on with his 

normal timeline of doing the MEB task. We'd also suggest if time 
permits to add a force evaluation using the device at the MEB 
station and that's on FS-11 and 12, box 19.

Vance, I don't know what's happening to me. Yeah. Have a 
(garble). You working on the lab boat. Stand by, Bruce. Bob. 
Yeah. Tell you what happened to me, they got the (garble) too 
far out, so when you pull a strip down over them, your really, I 
think they've got the (garble) too far in, so when you pull the 
strap down over it hard you're missing it. There's really too 
much slack, so what you've got to do, is feel for the (garble), 
with your fingers, and just sort of push them down over it. 
Okay. Did that help any. Yes. Okay, Bruce we're ready to put 
the arm I'm still rearranging the furniture here. Stand

someplace, and the (garble) will be dropped. Interesting 
enough. I can feel the vibrations, from you hitting that hook 
with that: tether reel. Okay. That's incredible, you know it. 
Okay, it looks like you're clear. I'll tell you why I take that 
right subway strip, put it around a mushroom, it got in my way, 
when I came back. Or you can worry about it later. Okav. looks 
good, Bob. (Garble). 

PAO Once Stewart checks out his - - 

SPACECRAFT Get back to work. 

PA0 checks out his MMU, he will do the same 

translations as McCandless has done. The 150 foot range and the 
300 foot range from the Orbiter. McCandless still in the 
manipulator foot restraint. Stewart earlier unable to complete 
his activities at the manipulator foot restraint. The EVA team 
would like for him to be able to go back and get some of that if 
there is time. The crew has been running a little behind. 

SPACECRAFT (garble) jets (garble). Houston Challenger, this 
is the point where I would take the Ku power to standby and 
panel, do you want that done? 

CAPCOM That's affirmative Hooter, and also on spec 33, we 

would like an item 2 execute with an asterisk this time. 

SPACECRAFT Okay, Vance, I'm heading out. Okay. 

PA0 Stewart moving away now from the Orbiter, they will 

use the Ku-band antenna for the tracking. So we will not be 
getting the television through that antenna. 

CAPCOM Challenger Houston, for Vance and Bob. 

SPACECRAFT Go ahead. 

CAPCOM Roger, Vance. Two things, if Bob experiences the 

same rattle that Bruce did, in X-translations , we would suggest 
that he attempt to do one without attitude holdon, see if that 
makes any different, and secondly because of timing here, I 
suggest that Bob translate to 150 feet, stop, readout the N2 
pressures, if it's good, proceed to 300 feet, and then return, 
over. ' 

SPACECRAFT Okay, what's your N2 pressure now, Bob? 
(Garble). (garble) Jerry, (garble) hold off, no chatter. 

CAPCOM copy, you don't get the chatter with attitude 

holdoff, Bob, thank you.

.65. Why don't you turn around and come on back. 

SPACECRAFT Hey what's my velocity. 

SPACECRAFT Opening at, standby. Okay we've got you closing 

now .75. 

CAPCOM Challenger, Houston. We're wondering how Bruce is 

progressing? 

SPACECRAFT Okay, Houston. I've qot 5 out 6 free screws out. 
I've got, I'm working on the sixth one. I've got all 4 of the 
captive screws loose and it looks like column 2 had locked 
tight. I'll tighten them up in a minute. Comment, the velcro 
holding the (garble) is not very affective. The blanket is too 
(garble) and the velcro is too weak so I'm having to fight that 
but otherwise, things are going along beautifully. 

CAPCOM Roger copy. 

PAO McCandless reporting on his activities. 

SPACECRAFT Bob, you're at 250 feet closing at .55. And 
Houston, we have the radar working good now. 

CAPCOM Roger, Vance. Copy that, thank you. 

SPACECRAFT Bob, what's your GU2 now? 

SPACECRAFT (garble) 

SPACECRAFT Okay, you're at 205 feet, closing at .8. 

PAO We're getting a television replay of the earlier 

recorded downlink EVA activity. Astronaut Stewart on his way 
back in and the crew aboard the Challenger tracking him with 
radar. 

SPACECRAFT We're looking good out there Bob. You're about

CAPCOM Challenger, Houston for Hoot. 

SPACECRAFT Okay, would you like to install a configure of TPAD 
and translate to the SPAS there Bob. 

SPACECRAFT (garble) doing that. 

SPACECRAFT Okay. And go ahead Houston. 

CAPCOM Roger, to stop the Ku-antenna from continuing 

(garble) we broke lock on Bob.s We'd like to take the Ku-band 
mode to manual slew. And also, Vance, our suggestions - - 

SPACECRAFT (garble) 

CAPCOM - - our suggestions on continuing the timeline here 

are for Bruce to continue the MEB task and then perform the force 
evaluation and for Bob to do some handling qualities there in the 
cargo bay, and if he thinks he can, to go ahead and install the 
TPAD by himself. 

SPACECRAFT Okay. Fine. 

SPACECRAFT I'm heading for doing that Jerry. 

SPACECRAFT And thought you might want to consider making a 
couple of passes at the SESA while I rap up here. On the pin on 
top of the SESA. 

SPACECRAFT Yeah I got you. 

CAPCOM And Bruce and Bob, we concur with that idea. And 

for Ron, Ron you'll have to be in the SPAS detach mode to be able 
to operate the cameras on there. 

SPACECRAFT Okay, Jerry. Thank you. 

CAPCOM Challenger, Houston. We're about 3 1/2 minutes to 

LOS TDRS. Guam is next at 03 + 06. We'd like a status on your 
Cinema 360 operations, and for Ron, once you've completed 
commanding the camera on the SPAS, we'd like you to go back to 
the attach mode, please. 

SPACECRAFT Jerry, I'll get over there as soon as I can. 

SPACECRAFT (garble) the APC in my hand and ready for the 
moment to get some cinema 360 shots. Tbe camera is set up, we 
have Fll set in there. 



CAPCOM 



Copy that Ron, thank you. 



STS-41-B AIR/GROUND TRANSCRIPT t226j 038:15:38 2/7/84 PAGE 2 

SPACECRAFT Okay, let's have another status check. You guys, 
have you lay your tools down. 

SPACECRAFT Okay, one second please. The (garble) lightinq i<= 
too bright to read it Vance. 

SPACECRAFT I can't read it either. 

SPACECRAFT Okay we can catch it later. Bob do you have one? 

SPACECRAFT It's too bright Vance. 

SPACECRAFT (garble) I think I'm going to oo ahead and shoot a 
few feet of you working (garble) so you may want that dome 
(garble) on the cinema 360. 

SPACECRAFT Yeah, yeah. 

SPACECRAFT The 360's (garble), we have bad lighting. Ah Jerry 
disregard that cinema 360 call. We've got the sun straight down 
m the bay and that's not going to work. 



CAPCOM 
Thank you. 



Okay, Ron, maybe we can get it at the next pass. 



SPACECRAFT Jerry, Jerry. 

CAPCOM Go ahead. 

SPACECRAFT I have a (garble) a little bit about an EVA flight 
(garble) boots. I can get in the foot restraints. Unbelievably 

difficult to force them in. 

CAPCOM Roger, Bob. Copy that. 50 seconds to LOS , was it 
width or height that was giving you the problem? 

SPACECRAFT (garble) It might be tee width, toe height, or heel 
thickness . 

CAPCOM Okay, copy, toe height, or heel thickness. 

SPACECRAFT Bob, I wouldn't wear myself out on that foot 
restraint.

SPACECRAFT It's a really useful tool for working though. It 
seems to be nice and stable. 

CAPCOM I'm glad to hear that. We'll pass it along to Bill 

TiOfman, Bruce. And we don't want to spend too much time on the 
SPAS. We would like to at least get one set of force of 
evaluations done, probably over on the sill considering where Bob 
is operating with MMU right now.

SPACECRAFT Bob, what's your sublimator pressure now? 
SPACECRAFT Hold on a second Vance. 

SPACECRAFT What's this furry looking thing with EV2 written on 

SPACECRAFT We just shut the water off Vance, the pressures 
coming up now. 

SPACECRAFT And Bruce, (garble) over here, is a different from 
the others. It's a little sticky getting it up and down. The 
thing hitting the water tar.k too. Okay, Vance the sublimator 
pressure's 2.3 now. 

SPACECRAFT Okay, it's coming up. 

SPACECRAFT Very slowly, it's 2.4. 

CAPCOM Challenger, Houston for Ron. 

SPACECRAFT Go ahead Jerry. 

CAPCOM Okay Ron, notes regard yur Cinema 360, 25 mm lens 

out the back, EV activities at night. For an ASA of 500, set 
your spot meter at l-60th and redirect the F-stop to use. 

SPACECRAFT Hey, guys, th^re goes a foot restraint into orbit. 

SPACECRAFT Don't worry Jerry, copied that, that's exactly what 
I had in mind, thank you. 

SPACECRAFT There it goes. 

SPACECRAFT We'll we can go get it. Houston Challenger. 

CAPCOM Go ahead Challenger. 

SPACECRAFT Houston, Challenger. We lost our foot restraint, 

it's starting to float out, we can go get it if you wish, with 
the Orbiter. 

SPACECRAFT Yeah why don't you. 

CAPCOM Roger, we see it, how much gas does Bob have? 

SPACECRAFT No the Orbiter. 

CAPCOM Okay your call. 

SPACECRAFT I'd let the Orbiter go get it. 



STS-41-B AIR/GROUND TRANSCRIPT t350j 040; 13: 31 2/9/84 PAGE 2 

CAPCOM Standby. 

SPACECRAFT I'm going to go get it. 

SPACECRAFT Vance you want me to go get it or - -? 

SPACECRAFT No, no, no, no. 

SPACECRAFT - - or continue with the (garble) . 

SPACECRAFT (garble) is off, he's going to do a rescue 
scenario, 

SPACECRAFT I think I'm going to hand on (garble) I guess you 
can't get it. 

SPACECRAFT Got it? We've got load of RCFs onboard. 

SPACECRAFT Give me your hand, he's coming back in. Bob f give 
me your hand. 

CAPCOM Challenger Houston, for Bruce. 

SPACECRAFT Go ahead. 

CAPCOM Roger, Bruce, can you give us a status on that foot 

restraint down there on the SfcSA, did it break off, or did it 
just come out, what happened? 

SPACECRAFT Looked like it pulled right out, I was going down 
to work on the secondary TPAD, and having completed the primary 
on the control box, and it just flew off. 

CAPCOM Roger, copy that, it's my recollection that we had 

a tether on that foot restraint. 

SPACECRAFT We took it off Jerry, to use it on EVA 1. 
CAPCOM Okay, understand. 

SPACECRAFT I'm at the end of my tether, Vance, your going to 
have to put in some -X.

SPACECRAFT Up at the end of my tether, Vance, you're going to 
have to furnish some minus X. 

SPACECRAFT I'm not completely out of the MMU yet, but I can 
come get it. 

SPACECRAFT No, just put in a little more -X, Vance. 

PAO Astronaut Bruce McCandless along the starboard 

slide wire moving back to pick up the free-floating foot 
restraint. 

SPACECRAFT Beautiful job. 
CAPCOM (Applause) 

SPACECRAFT At least, it won't be reentering in a few days. 

SPACECRAFT I hope it'll be reentering in a few days. The 
rest of us are planning to. 

SPACECRAFT Yes, they won't be reentering separately. 
SPACECRAFT There you go. 

SPACECRAFT Commander Vance Brand maneuvered the Orbiter. 
SPACECRAFT Houston, Challenger. 
CAPCOM Go ahead, Vance. 

SPACECRAFT Okay, we thought it might get away from us and so 
we we): and got it as you noticed and I guess the procedure works 
okay to go get it, to go . v >t things that get lost which we happen 
to have in our procedures. 

CAPCOM Roger that, Vance. We verified a procedure we 

didn't expect to use and you got some prox ops operations in that 
we missed earlier. 

SPACECRAFT The big thing to remember in that procedure is 
when you change from the upper window to the aft window to be 
able to, to be sure and throw the sense switch at the same time. 

CAPCOM Roger, copy that. There's always a "gotchya" in 

everything. 

SPACECRAFT So we were a few seconds late in doing that but we 
got it anyway. 

CAPCOM it looked super. You got a big round of applause 

down here. 



STS-4 1-B AIR/GROUND TRANSCRIPT t351j 040:13:38 2/9/84 PAGE 2 

SPACECRAFT Demonstration anyway. 

SPACECRAFT That's what we brought him along for. 

SPACECRAFT I didn't need to worry so much about my gas did I? 

SPACECRAFT I brought it back just for you, Bob, so you could 

do the hydrazine tool demonstration. 

SPACECRAFT Aw, thank you. 

SPACECRAFT I knew you wouldn't want to wrap up the day 
without that. 

PAG Crew of the Challenger with a little demonstration 

in rescuing free-floating objects. 

SPACECRAFT As far as I can tell, it's just a case of the 
(garble) down here having backed up. I'll tell you there's a lot 
of things up here that aren't locked (garble) or you know, in 
someway like that, secured, have a tendency after going through 
launch vibration, and being in Og with all the little vibrations 
from the RCS thrusters firing, have a tendency to work loose. We 
found screws from 16 millimeter cameras and various little things 
floating all over the place inside the cabin. 

PA0 Astronaut Bob Stewart exiting from his MMU at the 

present time. 

CAPCOM Challenger, Houston. Vance, you can go ahead and 

turn your flight controller power back off. Be advise you used 
150 pounds of prop and the EVA folks say bravo Zulu. 

SPACECRAFT Okay, good.

700 pounds system B. 

SPACECRAFT Okay, copy, thank you, Bob. 

SPACECRAFT Okay, I have TPAD assembly is stowed. If you come 
by here, Bob, you might take a look, make sure it agrees with 
the way it wau. (Garble) 

SPACECRAFT Okay. 

SPACECRAFT And I'll go over and get the SPAs wrench out of the 
PPSA and tighten these down if you'd like. The foot restraint. 

SPACECRAFT Okay, I don't know if that's really necessary. 
What do you think? 

SPACECRAFT I don't know, I'd hate to lose it again. Maybe 
this one will work. 

SPACECRAFT Jerry, I'll catch that 25 milimeter cinema 360 in 
the next night pass. It got a little bit too bright on me, and I 
really ran the f stops up too high. As you can see we have about 
a thousand cameras around, and kind of tough getting around all 
of them, but we're getting them in. 

CAPCOM Roger, it looks like you're doing a great job up 

there, Ron, I war going to say it looked like you had a camera 
shop going. 

SPACECRAFT It's plenty busy. 

p AO Astronaut McCandless working at the special

SPACECRAFT Okay, Bob, they're closed. 

SPACECRAFT Bruce, is that foot restraint reattaching okay 
there. 

SPACECRAFT Yes, yes. It's just that the, a hand wheel that 
held it in had backed out and when I put a little bit of a load 
on it, bingo. 

SPACECRAFT (Garble) going down that slide wire to get it. 

SPACECRAFT You just made it a little bit longer chain. 

SPACECRAFT Well you see what happened is, I was on the port 
slide wire and my cable came across the RMS shoulder brace joint 
there and I wouldn't slide and it's only 35 feet long, so I ran 
out of, I ran out of wire before I did. But that was great. You 
gave a little bit of, gave us a little bit of minus X, it just 
lifted right up. 

SPACECRAFT He walked back slowly to you. 

SPACECRAFT Yes. Okay, Dr. Stewart, that is tightened about as 
tight as I dare without worrying about breaking the (garble) or 
something. 

SPACECRAFT Okay. 

SPACECRAFT Still not getting helmet TV? 

SPACECRAFT Tried it again, Bruce, but no luck. Do you have it 
on now? 

SPACECRAFT I just changed the switch again. 
SPACECRAFT Give it another try. 

SPACECRAFT Okay. If you wait till I get back over to CBSA I 
can get out the hammer and hit myself in the head with the hammer 
if you think that would help, 

SPACECRAFT You could do it now. You don't have to wait. 

SPACECRAFT (Laughter). You're all heart. 

SPACECRAFT Hey Bruce, what are you looking at now? I am 
seeing something on that camera but I can't make any uense of it. 

SPACECRAFT The SESA. And now I'm loc - ^ at the forward

PAO McCandless working at the special equipment stowage 

assembly in which the hydrazine experiment is stored. 

SPACECRAFT Better make a note that the velcro on these 
butterfly strips is coming loose. It's not a very good security 
device the way it is now. 

SPACECRAFT Well the butterfly flap strips are supposed to be 
the security for the butterflies which are supposed to be the 
lock for the over center on the latch, so. Bob, are you 
referring to that configuration, the way it sticks out like that? 

SPACECRAFT (Garble) oh, it's film there isn't it. 

SPACECRAFT Yes that's, no, that's intentiona 1 . ♦ 

SPACECRAFT Okay, yes disregard. 

SPACECRAFT Yes, it is, to make it hard to pull loose. Flaps 
around like that, we might wrap the other one around like that 
and fit it on there. Okay, I'm going to head back on over to the 
port MMU and get ready to go try that, Vance. That's what the 
timeline says. 

SPACECRAFT Right, go ahead Bruce. 
SPACECRAFT Is that what the timeline. 

SPACECRAFT Okay, you need a wrist tether to take those - - 
SPACECRAFT Oh, yes. 

SPACECRAFT Let me get them for you here.

SPACECRAFT Let me get them for you here. 

CAPCOM Challenger, Houston, for Bruce and Bob. 

SPACECRAFT Go ahead, Jerry. 



Roger, Bob, we want the quick disconnects closed. 



CAPCOM 

Closed both of them, on both MMU's for 'closeout. 
SPACECRAFT That is pushed on, but close to flow right? 
CAPCOM That's correct, Bruce. 

Okay, that's what I thought the configuration ought 



SPACECRAFT 
to be. 



SPACECRAFT 



That's the way it is, isn't it? 



Yeah. Bruce, give me the cue (garble) and we'll 



SPACECRAFT 
worry about that 

CAPCOM Bruce, there's quite a bit of static now, but the 

next thing on the timeline is go to MMU prep, port MMU, with the 
thruster cue light extension and camera from the starboard MMU. 

SPACECRAFT Okay. (Garble) camera. Go around your back

Bruce? If you don't mind. ^ 

SPACECRAFT I'll get it for you in a minute, if you don't 
mind. Putting this SPA's umbilical tool back in the locker. 

CAPCOM Challenger, Houston, for Bruce. 

SPACECRAFT Say again. 

CAPCOM Roger, 3ruce, got a couple questions for you. 

SPACECRAFT Go ahead. 

CAPCOM First one is, did you reinstall the tether on the 

SESA £^ t m r ^ stra ! nt ' and se condly we're questioning the status of 
your EMU TV? It's one of the things we'd like to have for your 
engineering evaluation. 

SPACECRAFT Negative, I did not reinstall the tether, on the 
foot restraint. I did take the SPA's wrench, however, and really 
really torqued all the bolts down though, it's on there tightly. 

CAPCOM Okay, copy that, we would like you - - 

SPACECRAFT Ah Jerry. 

CAPCOM - - to reinstall the adjustable wrist tether, prior 

to closing out the cargo bay. And what is the status of your TV? 

SPACECRAFT Well do you want it adjustable wrist tether on the 
CDSA foot restraint, which is exactly the identical - - 



END OF TAPE

SPACECRAFT Well, do you want an adjustable wrist tether on the 
CBSA foot restraint which is exactly the identical thing and then 
latch with one? 

CAPCOM Stand by. 

SPACECRAFT And the status on the TV is that I have been 

cycling the switch, oh, every 15 or 20 minutes and we're getting 

nothing out of it. Can't even get a green light on. 

CAPCOM All right, understand that Bruce, and the answer is 

yes. We would like wrist tethers on both portable foot 
restraints. 

SPACECRAFT Okay. (Garble) Hey Bob. 
SPACECRAFT Yes. 

SPACECRAFT While you're there, why don't you see if there's 
anything you can do with this TV, pound on it once or twice or -

SPACECRAFT Jerry, on that EMU TV, apparently we are configured 
properly. As I've said, I am getting SPAS TV through okay. Just 
can't pick up anything on the EMU TV, over. 

CAPCOM Okay copy that, Ron. 

SPACECRAFT And Bob, where are you now? 

SPACECRAFT I'm closing out this MMU. 

SPACECRAFT Okay. 

PA0 Challenger crossing the coast of Southern Africa at 

the present time. 

SPACECRAFT Say again. 

SPACECRAFT Tell the guy3 at Martin I jubt put a scratch on 
there FSS. Might have to send it back to the paint shop. Sorry. 

SPACECRAFT How big a scratch. 

SPACECRAFT Well, it's on the inside arm here. It's a - - 
SPACECRAFT Did it go all the way through the middle? 
SPACECRAFT Oh no, no. Just the paint. 

SPACECRAFT And we're starting to get behind on the timeline a 
Little bit again. This time we'd have you into the engineering 
evaluation Bruce, and Bob into the hydrazine experiment. 

SPACECRAFT Okay, Vance. We'll be there very shortly. 

2ND OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t356j 040:14:05 2/9/84 PAGE 

SPACECRAFT Okay, Vance. We'll be there very shortly. 

SPACECRAFT What am I wrapped around, around with my tether. 
Bob? 

SPACECRAFT I got your tether running from your right side 
around your rear end, you'll have to turn a 360 to the right. 
Wait a minute, turn to the left. It's going the other way. 

SPACECRAFT Turn to the loft? It's coming off my left side. 

SPACECRAFT Yeah, I couldn't see which side it was coming off 
of. Okay the wires hanging under the Christmas tree fixture, 
Bruce, you have to pull the wire back towards you and do a 360 t 
the left. 

SPACECRAFT Okay. Yeah, here we go. 

SPACECRAFT Jerry, I think my RMS elbow camera's beginning to 
fade on me unless you're controlling from there, down there. 

CAPCOM No, we're controlling from down here, Ron, but it' 

starting to look not too healthy either. 

SPACECRAFT Hey, one of you, either one of you guys happen to 
wonder away from either, the longeron, let me know, I'd like to 
do another cinema 360 run before this pass is over. But only 
when you plan to do so. 

SPACECRAFT Okay, the starboard MMU is in there locked and 
launch bolts are in place. 

SPACECRAFT Okay, copy, Bob. 

SPACECRAFT Do you want both of the nitrogen valves, nitroqen 
isolation valves, closed? 

SPACECRAFT (Garble) 

SPACECRAFT That is just like you had, taking them loose, now 

just push it back on. Do not rotate after pushinq it on. 

SPACECRAFT That's exactly where I left it. 

SPACECRAFT Both of them? 

SPACECRAFT We'll I'm turning the one that I didn't, the one 

that I used, the bay side, is stored that way, the other one 

you re going to have to open up the cover, and just turn it 
off. 

SPACECRAFT Yeah that's what they want.

CAPCOM Challenger, Houston. 

SPACECRAFT Yes. 

CAPCOM Roger, Vance, couple of notes, because of the 

camera failures we're experiencing, for the MMU engineering 
evaluation, Bruce will have to give us verbal marks on the MMU 
thruster firings that he sees, in place of the camera on his 
head. And also for Ron, we'll want to use cameras alpha and 
Charlie for watching him do his test. 

SPACECRAFT Okav, Jerry, we copy all that. Roger, Bruce will 
have to replace the helmet mounted TV, by giving verbal marks. 

CAPCOM Roy-^r, that, and we're becoming somewhat shaky on 

TDRS comm. 3 minutes till LOS, Guam next, at 01+34.

circuit breakers for the port MMU (garble). 

SPACECRAFT Okay, stand by. 

CAPCOM Challenger, Houston, for Bruce. 

SPACECRAFT Go ahead. 

CAPCOM Roger, Bruce. Because or the lower pressure on 

this recharge, if you need to half way through you are go for a 
second recharge to complete your engineering evaluation. 

SPACECRAFT I don't think we got the time for that. Although 
maybe I could do it (garble) Jerry. 

CAPCOM Okay, that's your call there, Bruce. 

SPACECRAFT Okay, Bruce, port circuit breaker is coming closed 
now. 

SPACECRAFT Open. 

SPACECRAFT They're open. 

SPACECRAFT No they're not. 

SPACECRAFT Okay, they're open. 

SPACECRAFT No, they're not. I can see the lights on then and 

the gage is still out here. 

SPACECRAFT According to Ron, the breakers are open. Let us 
recheck. 

SPACECRAFT Okay, Bruce, port MMU heater B is open. 

SPACECRAFT Yes, I need heater A and B on the port MMU, both of 
them. B is now open, A is still closed. Okay, you got it. 
Thank you, sir.

SPACECRAFT It's partially revised attitude - - 

SPACECRAFT Okay, Break. Break. Break. 

SPACECRAFT Okay, we made it 1 degree, Bruce. 

SPACECRAFT Okay. I'm just getting impatient. I thought ;e 
were going faster than we were but, yes, well, okay. 1 degree is 
interesting because it's 1 and 1/4 plus or minus a 1/4 is the

about to move into the translational acceleration checkout. 

CAPCOM Go ahead, Vance. 

SPACECRAFT We are in dap D4 and B9, and A and B respectively, 
we're going into the translational acceleration test, what DAP 
would you like there? 

CAPCOM Stand by, Vance. A6 and Bravo 2, Vance. 

SPACECRAFT A6, Bravo 2. And I understand you want DAP A6 for 
the translational acceleration? 

CAPCOM Roger, Vance, we're rechecking that with some of 

the other folks. A6 and Bravo 2. 

SPACECRAFT Okay, Bruce, position MMU over port FSS, facinq aft

SPACECRAFT Ok, again on the starboard one, right? Is that 
affirmative you want to do (garble)? 

SPACECRAFT Hey Bruce, the answer's to use the C cameras, so 
the only way we're going to see you with the C camera on the 
starboard side. I have a shot of you right now. 

SPACECRAFT Okay. 

SPACECRAFT (garble) show you 50, about 56 feet, that sounds 
about right. 

SPACECRAFT Do you want me to face aft, is that correct? 

SPACECRAFT That's light, facing aft. 

SPACECRAFT Alright. This first one with the attitude hold on 
or off? Because it's on. (garble)

CAPCOM Copy that, Challenger. 

SPACECRAFT Okay, Bruce, what's, as soon as the DAP's set up 
what this will amount to is successive translations between FSS 
and the forward PAM. You will mz.k when you make a THC command 
input and you'll mark when you release and make no corrections 
during the coast, The first one is going to be attitude hold on 
and it will be +X for 4 seconds. 

SPACECRAFT Roger, I'm ready whenever you are. Ready? I'm 
ready whenever you are. 

SPACECRAFT Don't hurry us. We're setting up the DAP. 
SPACECRAFT Oh I'm sorry, I'm sorry. 

CAPCOM Challenger, going LOS. 7 minutes to Hawaii. 

PA0 t This is Mission Control Houston at 6 days, 1 hour, 

43 minutes mission elapsed time. We have a gap in communications 
with the Challenger. Just passed the Guam station and we'll be 
reacquiring over Hawaii in about 5 minutes. The crew is 4 hours 
and 20 minutes into this second spacewalk of this shuttle 
flight. The earlier planned activities, docking with the 
rotating SPAS on the mechanical arm were deleted due to some 
difficulties in some of the motions of the mechanical arm. The 
crew has done some TPAD operations, trunnion pin attached device 
operations wi*-.h the SPAS earlier. Astronaut Bob Stewart did some 
evaluation of his MMU. At one point we had one of the attachable 
foot restraints come loose. It was not tethered and began to 
float away from the Orbiter and Comman er Vance Brand maneuvered 
the Orbiter to match the drift rate of this piece of hardware and 
Astronaut Bruce McCandless moving down the starboard slide wire 
toward the rear of the Orbiter was able to retrieve that as the 
Orbiter moved into, in close to the drifting piece of 
equipment. That was recovered and installed on the special 
equipment stowage assembly. McCandless is now in his engineering 
evaluation of the MMU, has been working on the automatic attitude 
hold evaluation. The Orbiter is used as a stabile platform from 
which to get some photography of the MMU and its attitude hold 
test to determine how stabile it is in the automatic attitude 
hold. And McCandless, following that, will move on to the 
translational acceleration test and then the rotational 
acceleration test of the MMU. Astronaut Bob Stewart will be 
doing the hydrazine transfer test. There is a special piece of 
equipment onboard the Orbiter this time which will, which is a 
representation of a hydrazine transfer tool to be used in the 
future to service satellites. Hydrazine is a fuel used by many 
satellites for their attitude control while they are in orbit. 



STS-41-B AIR/GROUND TRANSCRIPT t359j 040:14:41 2/9/84 PAGE 2 

It is one of the life limiting factors of many satellites and 
this will be a servicing test confirming the ability to actually

their hydrazine tanks refolled. This particular test will

PAO many satellites for their attitude control while 

they are in orbit. It is one of the life limiting factors of 
many satellites, and this will be a servicing test confirming the 
ability to actually transfer that fluid in orbit so that future 
satellites may have there hydrazine tanks refilled. This 
particular test will involve transfer of freon rather than 
hydrazine on the first test. Hydrazine is a very dangerous fluid 
to handle, so this test will be using freon with a dye in it so 
that any leaks might be observed. We 1 11 be picking up in about a 
minute and a half over the Hawaii station. At 6 days, 1 hour, 47 
minutes, this is Mission Control Houston. 

SPACECRAFT Okay, you need to feed out just a little further 
Bruce so the helmet mounted TV can see the back of your head. 
SPACECRAFT Okay. 

SPACECRAFT Rather the lazer can see the back of ycur head. 
SPACECRAFT Yes, I got the idea. 

CAPCOM Challenger, Houston. Hawaii for 7 minutes. We've 

got a couple breakers we'd like to check. 

SPACECRAFT Okay, go ahead. 

CAPCOM Roger, Vance. ML86 bravo, row A, we would like to 

check circuit breakers main alpha and bravo H20 line heaters. We 
think they should be closed. 

SPACECRAFT Okay, Hoot's going down to check those, and as soon 
as he reports back, Bob has something to talk over with you. 

CAPCOM Okay. 

SPACECRAFT Say Jerry, your main A and main B water lines 
heater A and B are both closed. 

CAPCOM Okay, Hoot, thank you, and standing by for Bob. 

SPACECRAFT Okay, the hydrazine transfer stuff is going very 
smoothly up until installing the (garble) tool. At this time, I 
cannot get the quick disconnect seated. I've gotten out of the 
foot restraints, put as much force on it as I can, and there's 
something there that just won't let that little quick disconnect 
push into the slot. 

CAPCOM Okay, we copy that Bob. We got a set of tools 

here. We'll start looking at it right away. 



SPACECRAFT Okay. Bruce as soon as Hoot gets back upstairs, 
we're ready for the test with sill attitude hold. 



STS-41-B AIR/GROUND TRANSCRIPT t360j 040:14:46 2/9/84 PAGE 2

SPACECRAFT Okay. 

SPACECRAFT Okay, Bruce, we probably need a repeat on that 
because we got off your head too fast and we had rotation effects 
added in. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston. Be advised we have commanded 

the Ku to on for TV coming up TDRS and also be advised that you 
are on transmitter 1, preamp 1. No actions required. 

SPACECRAFT And Jerry, just for a status report on hydrazine, 
the only task remaining, everything is seated. I just have to 
twist the freon valve open but the quick disconnect on the other 
end of the line will not stay seated. 

CAPCOM Okay, Bob, we copy all that. We're looking at it 

here on the ground. We don't know what else to recommend right 
now, Bob. We'll think about it and talk to you further and also, 
be advised, Vance, as soon as you can we'd like you back into 
auto so we can get good comm through the Ku. 

SPACECRAFT Okay, well after the tests we're doing right now we 
will still have 2 yaw maneuvers but before we do those we could 
go into auto and get back into the attitude. 

CAPCOM Okay, that sounds like a good idea to us. We're 1 

minutes till LOS Hawaii. 



SPACECRAFT Okay. 

SPACECRAFT Okay, I'm ready. 

SPACECRAFT Okay, let here rip. 
SPACECRAFT Okay. (Garble)

SPACECRAFT Understand. (Garble) this will be the last one of 
these 4 second blast, and I think they only got some rotations up 
here, which are fairly suttle. The EMU jets check and things 
like that. Or we could do a flying recharge. 

SPACECRAFT Anybody else up here, that could come up and qive 
you a recharge, huh. 

SPACECRAFT No, I mean I could fly over near Bob, and he could 
hook a hose on, and fill me up without even getting in the FSS. 
Another first - space-to-space refueling. 

SPACECRAFT if he's agreeable.

SPACECRAFT I'll be the little guy they carry off on the 
stretcher after every kick off. 

SPACECRAFT Houston, how do you like that Earth, view of the 
Earth there? 

CAPCOM Roger Vance, that's absolutely beautiful. It gives 

you a good break, to sit and look around for a little while. 

SPACECRAFT Okay. 

SPACECRAFT Jerry that one may not be as pictureous, but 
composition wise, how is it? 

CAPCOM Composition is fine Ron, it's a little bit dark 

right now. And we got a good shot of you there in the fliqht 
deck. 

SPACECRAFT Bruce, we can't hardly see you down there, why 
don't you come up just a little bit. 

SPACECRAFT Ok . 

SPACECRAFT I got plenty of shade up here Bruce. 

SPACECRAFT You what? 

SPACECRAFT Still in plenty of shade, if your warm. 

SPACECRAFT No, I'm freezing, (garble)

STS-41-B AIR/GROUND TRANSCRIPT t367j 040!l5!27 2/9/84 PAGE 2 

REAGAN good morning to you and your crew. I'm talking 

to you from California, I don't know exactly where you are, I 
know your up there someplace, but you're all doing a fine job on 
this historic mission, and I'd like to say hello to Bruce 
McCandless and Bob Stewart, for sending us this spectacular 
television coverage of man's historic walk in space. Let me ask 
you, what's it like to work out there, unattached to the ShMttle, 
and maneuvering freely in space? 

SPACECRAFT We'll we've had a great deal of training, sir, so 
it feels quite comfortable. The view is simply spectacular in 
panaramic and we believe every units first time working 
unattached we're liter aly opening a new frontier in what man can 
do in space, and we'll be paving the away for many important 
operations on the coming space stations, sir. 

REAGAN well that is just great. You've really opened a 

new era for the world in space with this mission. You've shown 
both our commercial partners and our foreign partners, who plav 
an important role in this and other missions to come, that man 
does have the tools to work effectively in space. You, I 
understand, you had an opportunity this morning, an unexpected or 
unscheduled thing, maneuvering the Shuttle and making a recovery 
of an object in space. Commander? 

SPACECRAFT Yes sir. 

REAGAN What do you and Hoot Gibson and Ron McNair do while 

Bruce and Bob are working outside? 

SPACECRAFT Well, we're pretty busy in here, just keeping track 
of them. They have a lot of tests to go through, of course it is 
the first check out of something that's rather futuristic, the 
backpack, the Man Maneuvering Unit, so we're just monitoring them 
making sure that we don't lose sight of them. 

REAGAN That's good. Say Hoot, I understand you must have 

a special interest in making sure everything's working right up 
there, since your wife will be making the trip onboard the 
Shuttle this summer. Do you have any tips to pass along to her? 

SPACECRAFT That's true, Mr. President, she is, she is going up 
about in August, and that's why like you say, I'm trying to check 
everything out and make sure it's going to work we'll when she 
goes. The thought of myself going up doesn't bother me, but I 
think I will be nervous when she goes. 

REAGAN I can understand that. Do you think she will enjoy 

it? J 1

SPACECRAFT Roger, on camera delta would you like to do that 
yourself to point it into the center of the bay or would you 
prefer Ron to. 

CAPCOM Well, I guess we want to know where you plan on 

having Bruce. That's who we're going to be pointing at and we 
cannot drive it. It's not tiltable. 

SPACECRAFT Bruce, would you tilt the camera such, camera delta 
such that it's pointing more or less at the trunnion pins. 

SPACECRAFT Okay, in work. 

SPACECRAFT As in elevation. 

PA0 McCandless hovering above the payload bay in his 

MMU while Stewart works at the special equipment stowage assembly 
with hydrazine transfer test. 



SPACECRAFT 



Okay, you all are panning it I can see. 



SPACECRAFT Yes, Bruce, I think the elevation is good 
already. I'm just panning it around to point at the SPAS TPAD. 

SPACECRAFT And Bob, in a few minutes where would be a good 
place for you over in the center of the bay? 

SPACECRAFT It would be hard for me to get to the center of the 
bay, Vance. 

SPACECRAFT Okay, why don't we put, have you go down the 
starboard slide wire and get over in that area about where the 
SPAS comes over to the starboard slide wire. 

SPACECRAFT Okay, I'll go down the port slide wire and 
translate across. 

CAPCOM Challenger, Houston. 

SPACECRAFT You're on the starboard slide wire now. 

SPACECRAFT Am I? Oh yes, I'm up across the bay aren't I. 
Okay. 

SPACECRAFT Hey, Bob, give me a long count.

CAPCOM Challenger, Houston. 

SPACECRAFT Yes, it seems to. 
SPACECRAFT Go ahead, Houston. 

CAPCOM Roger, Vance, before Bob leaves the SESA there 

we d like to get a camera A view of him with the ORS activity and 
also, can you give us a status of where the 2 guys are with 
respect to their task? 

SPACECRAFT Bob is nearly finished with the hydrazine but he 
came up with that hang up in the QD. Bruce is in the, taking the 
Z translation last step of the translation test and I think 
everybody is just about ready to move to the starboard center of 
the payload bay. 

CAPCOM Roger, copy that. Thank you. 

SPACECRAFT How does the camera delta angle look to you, Ron? 

SPACECRAFT It looks good, Bruce. it all depends on where 
you re going to end up. if we're looking at the SPAS TP AD we 
have a very good view. 

SPACECRAFT That's good on elevation. Bruce. 

SPACECRAFT okay. I need to come back inside the bay. I'm 
getting extremely cold.

SPACECRAFT Sure, that's fine or just kind of on top, or 
whatever. Why don't we take a 5 minute break here, and then 
finish up these tasks. 

SPACECRAFT You want me behind the SPA's or in front of it. 
SPACECRAFT On our side of it. 
SPACECRAFT Okay. 

SPACECRAFT Or over a little closer to Bob, up higher. 

SPACECRAFT Okay. Oh boy, it feels better down here in the 
bay. Where is, Bob? 

SPACECRAFT Just outside the starboard side. Suppose I confuse 
the starboard and port a while ago, you know I'm in the Army. 
You know, we use left and right. I never heard anybody yet say 
starboard flank march.

sure it's going to well when she does it. The thought of myself 
going out wasn't bothering me but I think I'll be nervous when 
she goes. 

PRESIDENT REAGAN I can understand that. Do you think she'll 
enjoy it? 

SPACECRAFT I know she'll enjoy it. 

PRESIDENT REAGAN Well now, could I ask how are the experiments 
onboard the Shuttle working out? I understand that you have one 
dealing with arthrizis and other experiments onboard that may 
lead to advances in manufacturing and various kinds of material 
processing. 

SPACECRAFT Mr. President, the experiments are working out very 
well. We're very pleased with the results we're seeing and 
there's a lot of promise being demonstrated in all the areas 
you've just mentioned and wo look forward to getting them back on 
the ground, analyzed and mako some good use of these results. 

PRESIDENT REAGAN Well, let me again congratulate all of you 
onboard the Space Shuttle Challenger, You're doing a fine job. 
Your committment and courage on this historic flight I think are 
an inspiration to all of us. And I know that you have things to 
do and much more important than getting a telephone call from 
Earth so let me just say to you have a safe journey home and God 
Bless you all. 

SPACECRAFT Thank you very much for calling, sir. We really 
appreciate that. 

PRESIDENT REAGAN It's my pleasure. All right. 
SPACECRAFT We're all proud to be a part of this mission. 
PRESIDENT REAGAN All right. Good bye.

Bruce McCandless had docked him MMU into the port flight support 
station and was locking it in place. EVA has been underway for 
about 5 and 1/2 hours and the crew will be closing out that 
activity very shortly and reentering the airlock. During the 
last pass, of course, they got a message, a phone call from the 
President calling from California to congratulate them on their 
activity. This EVA marked primarily by the engineering checkout 
of the Manned Maneuvering Unit and the operation of the hydrazine 
transfer test. One of the planned activities, one of the, what 
would have been one of the highlights of this EVA was cancelled 
due to an equipment problem. The crew was due to dock, practice 
docking with a slowly rotating SPAS on the end of the Remote 
Manipulator Arm and due to a malfunction in the armn that task 
was unable to be conducted. Spacecraft is in a 156 by 149

like to have us go to the no vernier aft check configuration, is 
that, as soon as we get everybody in. Is that correct? 

CAPCOM Well, that's essentially it Vance. If you can 

refer to 65 when you get it, it'll have the complete story for 
you. 64 tells you what we've learned about the CG calculation 
question you had earlier in the day.

example, right? 

SPACECRAFT Yeah, the hammer is back, we can, I can account for 
everything that we've brought out on this EVA, Vance. There's 
still one tether missing of stuff tha we brought in last time,

~ ~ 3 hours, 56 minutes. Mission Specialists Bruce 
McCandless and Bob Stewart concluding the activities in the 
airlock there. They will be getting out of their suits 
shortly. Suits are, again, mounted on the walls of the airlock 
and they are getting their cooling supply and their electrical 
power and oxygen from the Orbiter, the mounting stations there in 
the airlock. The EVA lasted for 6 hours, 17 minutes today, 
That s about 20 minutes longer than the EVA on flight day 5. Had 
an unexpected demonstration of the MMU rescue capability on this 
EVA today. As McCandless was working with one of the portable 
foot restraints, it slipped off of a mounting and began moving 
away from the Orbiter on its own, became a free-flying satellite 
and the crew decided to go get that using the techniques that 
they would use should it ever become necessary to rescue an MMU 
astronaut out flying his MMU who would have some sort of failure 
and be unable to return, the Spacecraft would go get him. That 
same set of techniques was used in retrieveing the toot 
restraints. Commander Vance Brand maneuvered the Orbiter using 
the thrusters to match up with the drifing piece of hardware and 
Astronaut Bruce McCandless moving down the starboard hinge line, 
managed to reach out and grab the floating foot restraint as the 
Orbiter moved up to it. That was a fairly efficient operation in 
that it only used about 150 pounds of propellant to put the 
Orbiter through that maneuver. The Orbiter currently weighinq 
well in excess of 200,000 pounds. We are expecting to hold a 
Cnange-of -Shift Press Conference in about an hour here in the 
Johnson Space Center Press Conference room 135 in building 2 and 
that would be with the Flight Director John Cox who has been 
directing the activities in Mission Control for the duration of 
this spacewalk today. He will be available for a Change-of -Shi f t 
Press Conference about an hour from now and we'll keep you 
advised as to the actual set up with the time on that and any 
other participants in that briefing as we get a little closer to 
that time. Challenger now moving out off the coast of South 
America out onto the open Atlantic. We're getting television 
relayed to us by the payload bay cameras as relayed to the 
tracking data relay satellite and back down to the White Sands 
New Mexico ground stations.

about 2 and 1/2 degrees maximum elevation although we show it as 
total contact about 2 minutes and 44 seconds during that pass. 
The next pass after that of any size is Hawaii 32 minutes from

CAPCOM Challenger, Houston. Vance, they wanted to leave 

it on the 10 degree deadband for sleep tonight. They thought 
that might be better than the 5 degrees you slept with last night 
and they were sort of wondering how it was sleeping in tail onlv 
last night. 1 

SPACECRAFT Okay. Well, that'll be real fun. I haven't polled 
the crew but I don't think we had any trouble sleeping. I know I 
could hear a muffled boom once in a while but it didn't bother me 
at all. And Hoot says it didnt' bother him. 



STS-41-B AIR/GROUND TRANSCRIPT t382j 040:18:05 2/9/84 PAGE 

CAPCOM That's good, then 10 degrees is a good enouqh 

deadband for us, 

SPACECRAFT Very good, we'll leave it at 10. 

CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead Mary. 

CAPCOM Roger Vance. Got a number of presleep notes to ge 
to you when you're ready to copy. 

SPACECRAFT Okay, copy. 

CAPCOM Roger. First of all, we don't have to do this now 

if you re busy doing something else Vance. It's iust at vour 
convenience first of all. 

SPACECRAFT Okay, well that's okay. We're ready to copy. 

CAPCOM Okay, first of all we'd like to go ahead again 

tonight and inhibit the FDA on decom 4. 

SPACECRAFT Okay. 

CAPCOM Also, just to get you generally give you an idea 

what we have planned for this evening before we let you turn in, 
we'd like to try to do a water dump and I have a note to set you 
up on that. And then also we'd like you, right before you go to 
sleep, to do a hot fire on two of your forward verniers and 
that's so you don't get alarms during the evening. And also 
sometime before sleep period, when the SPAS folks see 
temperatures they like we're going to go ahead and have you 
deactivate the SPAS. 

SPACECRAFT Okay, understand things coming up this evening. 
Inhibit FDA to decom 4. You'll give us instructions on a water 
dump I presume after we've had some heat soaking on the nozzle. 
A hot fire on 2 vernier engines and I guess that's because 
they re cold, is that correct, and deactivate the SPAS. 

CAPCOM Roger that's correct and on both counts that water 

dump is going to be tied into the terminator, we're trying to 
heat up that side before you go ahead and dump. And also, the 
hot fires are to avoid alarms. 

SPACECRAFT Okay. So

STS-41-B AIR/GROUND TRANSCRIPT t383j 040:18:41 2/9/84 PAGE 1 

SPACECRAFT hot fire on two venier engines and I guess 

that's because they're cold, is that correct, and deactivate the 
SPAS . 



CAPCOM Roger, that's correct on both counts, that water 

dump is going to be tied into the terminator we're trying to heat 
up that side, before we go ahead and dump, and also the hot fires 
are to avoid alarms. 

SPACECRAFT Okay. So we'll get further instructions later 
then. 



CAPCOM 

really matter, 



Roger, or we can read it to you now, it doesn't 



SPACECRAFT Can you standby just a second. Okay ready to copv 
instructions on the water dump. Ky 

CAPCOM Okay, for this supply water dump, we're going to 

let you go for, and then for the second sun side, we'd like you 
to get this heater on, on panel R12, your supply water dump valve 
enable nozzle heater on, and that's at time 7+00. And then when 
your nozzle temperature is greater than 300 degrees fahrenheit 
we d like you to go ahead and dump by going to R12 taking your 
supply water dump isol valve open, talkback open. And you can 
check that your tank bravo quantities decreasing. You should try 
to start that dump just prior to the terminator to give yourself 
the maximum amount of sunlight along with the heater on, to try 
to work on that system. If you don't get a dump, the cleanup is 
supply water dump isol valve, close, talkback, close. And then 
take your valve enable nozzle heater off, also. If the dump 
works, we;d like you to dump tank bravo to 20 percent, and when 
the dump is complete on R12, take your supply water dump isol 
valve closed, when the nozzle temperature is greater than 100 
degrees, you can take your heater off, over. 

SPACECRAFT Okay, Mary, I understood most everything about 
that, we're going to try and supply water, dump R12, we're going 
to turn the dump valve enable nozzle heater on, at 7+00 when we 
get over 300 degrees, we'll go ahead and start the dump by 
opening the dump isol valve, if the dump does not work then 
we re going to close the dump isol valve, and we're going to, 
okay the part after that was the part that I didn't understand. 

CAPCOM Roger, if you do not get a dump, we want you to 

close that isol valve, and then also take the heater off. Your 
valve enable nozzle heater will go off. 



SPACECRAFT Okay, and what was the part that had to do with 100 
degrees Mary? 



STS-41-B AIR/GROUND TRANSCRIPT t383j 040:18:41 2/9/84 PAGE 2 

CAPCOM Roger, if you get a good dump, your to take bravo 

down to 20 and then when the dump is complete, on take, your 
supply water dump isol valve close, and then wait for your nozzle 
temp to heat back up to 100 degrees fahrenheit before you take 
your nozzle heater back off. Over. 

SPACECRAFT Okay, Mary, you were cut out on that one, say again 
please. 

CAPCOM Okay, for the third time, we'd like you to take 

your supply water dump isol valve closed when you get bravo to 20 

percent, and then before you take the heater off we want that 

nozzle heater temperature to get up to greater than 100 degrees, 

S ^u e ^ your , nozzle neat back U P before you take your heater off 
with the valve enable nozzle heater off. 

SPACECRAFT Okay, great, I understand that now, so if we do get 
a dump we 1 re going to let that nozzle warm back up before we turn 
the heater back off, so let them get above 100 before we take the 
heater off. 

CAPCOM That's affirm, and then we've got some clean up 

also since we got that tank C and D back from the EVA guys that 
ECCOM would like you to do. When your at R12 you can take your 
supply water tank C inlet back to open to get back in your 
standard config. Also when your down in the middeck sometime and 
there is no rush on this, you can take your tank delta outlet to 
open. 

SPACECRAFT Okay, Mary you cut out during part of that, I think 
you said take the tank C inlet open, take the D outlet open. 

CAPCOM That's affirm, and that is any time. It's just a 

cleanup, now that we've got the tanks char lie and delta back from 
the EVA guys. 

SPACECRAFT Okay, we'll do Mary, thanks. 

CAPCOM That's the end of the supply water dump saga for 

this evening, and we're ready to give you the venier iet test if 
your ready to copy. 

SPACECRAFT Standby one. 

CAPCOM No rush on -

STS-41-B AIR/GROUND T KAMSCR. £PT t.UMj 040: 18: 47 2/9/84 PAGE 1 

CAPCOM - - the end oi the supply water dump saga foe this 

evening, and we're ready to give vou the venier jet test if your 
ready to copy, 1 

SPACECRAFT Standby one. 

CAPCOM No rush on this Vance, have a couple of other notes 

too. Questions on the Cinema 360, and payload stuff also, if 

?? n, L2 n J£ e .£ ine# And for Hoot ' have a couple of questions on 
the RMS FDI if your still on the line. 

SPACECRAFT Yeah Mary, I'm still with you. 

CAPCOM Okay, they'd like to talk to you about this while 

the information is still real fresh in your mind. During that 
RMS problem, it appeared from the conversation and the fact that 
the crew continued to drive, after the fault occurred, if, that 
you may not have heard that alarm, and we'd like to know if you 
did hear that alarm. 

SPACECRAFT Yeah, Mary I wrote that down in my notes for post 
flight debrief. That is a fact, I did not hear that alarm. We 
had the movie light on in the cabin, and that movie light made 
enough noise and the volumn on the MCIU, was turned down low 

?h»!? 9 5 «!? at -V? f ? Ct . d i d n0t hear tnat alarm ' and the ^ason 
tnat I started to look for something, was because the arm wasn't 
following exactly what I was asking it to do. And I looked back 
in the cockpit and that's when I saw the (garble) light on. 

CAPCOM Roger we copy that, they got an action here, they'd 

like you to do if you didn't hear the alarm, which is on A8, 
parameter select to test, then port temperature and you should 
get an alarm. 

SPACECRAFT Okay, well Mary the alarm does work, but the volume 
is turned way down, and it's just turned down enough that with 
that cabin movie light going, which has a fan on it, that it just 
didn't make quite enough noise to be heard. 

CAPCOM Okay, Hoot, thanks. Now I understand, just didn't 

really understand that you weren't hearing the alarm, thanks. 

SPACECRAFT Mary, there's a couple comments regarding the EVA 

CAPCOM Roger, Bruce, ready to copy. And if your going to 

debrief that tonight though, we'd like to get the times, so we 
can get a dump and look it over this evening. 

SPACECRAFT Oh we will do that, the comment that we're going to 
give you is, we've put the 2 EMUs on battery recharge, but other 
than that we have not performed the LiOH cannister changeout, nor 



STS-41-B AIR/GROUND TRANSCRIPT t384j 040:18:47 2/9/84 PAGE 2 

do we intend to, and we have not recharged, perform water 
recharge, nor do we intend to. We figure that if they're needed 
for contingency EVA, we can do both of those relatively rapidly, 
and why cycle the (garble) and use up Li OH cans. We expect to 
terminate the battery charge sometime tomorrow, over. 

CAPCOM Roger Bruce, it's as if you were reading this 

flight note to me that we're going to give you, send you up to 
the teleprinter tonight. We concur with all that. 

SPACECRAFT Okay, thank you. 

SPACECRAFT And Houston, Challenger. 

CAPCOM Challenger Houston. 

SPACECRAFT Roger, Mary, did you want to give us something then 
on the hot fire? 

CAPCOM Yeah, I'm standing by to read that to you, as soon 

as your ready to copy. 

SPACECRAFT Ready to copy. 

CAPCOM Okay, first of all Vance, we'd like you to do this 

as late as you can in presleep, so the jets don't have as much 
time to warm up, cause it is because the forward RCS venier jets 
are cooling down, and we don't want you to get an alarm, a jet 
leak alarm during sleep. So we'd like you to take the dap to A 
manual venier and your rotation, excel, excel, excel. Take your 
RHC and do a positive pitch for 5 seconds, and then reconfigure 
your dap to A auto norm, and your rotation is discrete, discrete, 
discrete, over. 

SPACECRAFT Okay, Mary, this hot fire should be done late in 
presleep, dap should be A manual venier, excel, excel, excel, RHC 
pitch for 5 seconds, and there's something in there I didn't 
hear, and then back to A auto normal, and discrete, discrete, 
discrete. 

CAPCOM That's a good read back, Vance and that RHC is a 

positive pitch for 5 seconds. 

S P ACECRAFT (garble) 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t385j 040:18:52 2/9/84 PAGE 1 

SPACECRAFT - - A auto normal and discrete discrete discrete. 

CAPCOM That's a good readback, Vance, and that RHC is a 

positive pitch for 5 seconds. 

SPACECRAFT Okay Mary, you were cut out. Please say the last. 

CAPCOM Roger Vance. The RHC motion is to be a positive 

plus pitch for 5 seconds. 

SPACECRAFT Okay, plus pitch 5 seconds in vernier, got it. 

CAPCOM Also have another note from ECOM about your rad 

controller out temp and working the FES this evening. 

SPACECRAFT Go ahead. 

CAPCOM Roger. On LI we'd like the radiator controller out 

temp to normal and then your flash evap primary A cycled off and 
then on. 

SPACECRAFT In work. And I guess that's because you feel we're 
in pretty good shape with tank B, 49%. 

CAPCOM Roger, Vance, and opening up the C and D inlets 

should let it - allow it to spill over if it gets full. 

SPACECRAFT Okay, very good. 

CAPCOM Challenger, Houston, for Hoot. 

SPACECRAFT Stand by. Go ahead, Mary. 

CAPCOM Roger, Hoot. We'd like you to know that tomorrow 

that PHS DTO is on your call only if you feel that you want to do 
it and the system's configured properly. 

SPACECRAFT Okay, Mary, you were interrupted by a hammer. Say 
that again. 

CAPCOM Roger, Hoot. We want you to understand the PHS DTO 

that's scheduled for tomorrow is on your call only and to be done 
only if you feel like the sy«*-<*m is configured to handle it. 

SPACECRAFT Okay, understand. Thanks a lot, Mary. 

CAPCOM Sure thing. 

SPACECRAFT Mary, isn't that more a question of the redundancy 
question from the separator? 



STS-41-B AIR/GROUND TRANSCRIPT t385j 040:18:52 2/9/84 PAGE 2 

CAPCOM That's affirm, Vance. If you feel like the 

separator isn't going to cause you trouble, if it's been workinq 
real well and you want to do it go ahead and do it because we can 
recover flooded separators supposedly. But if you don't want to 
be bothered, that's fine. We understand because we don't have 
redundancy you don't need to do the test. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston. Got a couple of pay loads 

questions for you. Need the footage that you used for both the 
cinema 360, both the cinema 360 cameras and also need a GAS qrouo 
activation time from this morning. p 

CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead. 

CAPCOM Roger, Vance. Just have a couple more items to 

clean up here, briefly. We need the footage used in both cine va 
360 cameras and then time for a GAS group activation this 
morning . 

SPACECRAFT Okay, we got that. Okay, Mary, we'll get those to 
CAPCOM Okay, thanks. 

SPACECRAFT Ron is right in the middle of a data take right now 
or else he could give them to yo>: but we'll have to have him give 
them to you when he's done. 

CAPCOM That's fine, just anytime presleep and we still owe 

you a call when the SPAS needs to be deactivated and otherwise 
everything's all caught up down here so we'll stop bugging you. 

SPACECRAFT Okay, good. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston. 

SPACECRAFT On this PHS thing, we'd rather defer the 
decision. We'd like to see how the weather's looking for the 
next day for landing and we have two volunteers signed up to 
change the filter if required but we'd also like to have a warm 
feeling that running that doesn't put stress on our good 
separator, that might cause our good separator to fail. 

CAPCOM Challenger, Houston. Understand that, Vance, 

sounds like a good plan. We'll update you tomorrow - -

CAPCOM Challenger, Houston. Understand that, Vance. 

Sounds like a good plan. We'll update you tomorrow on the 
weather but right now it's looking real good for KSC on Saturday. 

SPACECRAFT Okay, well let's revisit this PHS thing sometime 
after noon tomorrow. 

CAPCOM Okay, that's fine. Thanks. 

CAPCOM Challenger, Houston. We're going LOS TDRS and 

we'll talk to you through Guam at 6 26. 

SPACECRAFT See you at 6 26. 

PA0 Mission Control Houston. 6 days, 6 hours, 4 

minutes mission elapsed time. We've had loss of signal through 
the tracking data relay satellite. Challenger's on orbit #101 
and we are less than 2 hours away from the start of the crew 
sleep period. Crew will be going to bed about 3 pro central time 
today. This is the point of the day in which Flight Controllers 
here in Mission Control begin reviewing the status of the Orbiter 
systems, set all the appropriate caution and warning limits so 
that the crew is not awakened during the night. They're 
reviewing those items now and looking back over the day's EVA 
activities. Crew will be getting up about 11 pm tonight central 
time to start their next flight day, flight day 8 and the final 
full day of the mission 41-B. We're about 21 minutes before 
reacquiring communication with the Challenger through the Guam 
station. This is Mission Control Houston. 

p AO Mission Control Houston. 6 days, 6 hours, 25 

minutes. Have a brief pass over the Guam station coming up for 
about a minute and then we'll pick up again over Hawaii. 
Challenger on orbit #101 at the present time. We're an hour and 
a half away from the beginning, scheduled beginning of the crew 
sleep period. 

CAPCOM Challenger, Houston, with you through Guam for 2 

minutes. 

SPACECRAFT Loud and clear, Mary. 

CAPCOM Got you loud and clear too. Challenger, Houston. 

For your information, you should have onboard now your block 
weather update for this evening and that's message 66. 

SPACECRAFT Okay Mary. We're just waiting for the high power 
light to go off before we pull the paper so we don't mess up that 
message in the process of being received. 



STS-41-B AIR/GROUND TRANSCRIPT t386j 040:19:02 2/9/84 PAGE 2 



CAPCOM Copy that. And we're about 15 seconds LOS. We'll 

talk to you through Hawaii at 6 36. 

SPACECRAFT Okay, Mary. 

SPACECRAFT Fine thank you. The same to you. (garble) 

PAO Mission Control Houston. We just had a brief 

contact there over the edge of the range of the Guam station and 
we'll pick up again in about 7 and 1/2 minutes through Hawaii.

minutes. 



SPACECRAFT (Garble) Houston, Challenger. 
CAPCOM Challenger, Houston. 

SPACECRAFT Mary, we're holding off on the hot fire until late 
in presleep like you requested. Question, would you like to 
particularly view that or are you happy if we just run off and do 
it by ourselves? 

CAPCOM Let me check on that for you. Challenger, 

Houston. Vance, that's not - -

do that ourself. 

CAPCOM Let me check on that for you. Challenger, Houston 

Vance, that's not necessary. They can get it through playback. 

SPACECRAFT Okay, good. 

CAPCOM And Challenger Houston, on your SPAS deactivation 

time? 

SPACECRAFT Okay, go ahead. 

CAPCOM Roger, Vance, you're clear to deactivate the SPAS 

by the payload Ops checklist page 5-2, any time after 7+00. 

SPACECRAFT Okay, copy that.

CAPCOM - - Bruce, well if you're down on the middeck we've 

got a circuit breaker we need opened if you're ready to copy. 
It's on ML86 bravo row alpha. 

SPACECRAFT You want it opened? 

CAPCOM That's affirm. The circuit breaker on ML86 bravo 

row alpha is main A water line heater alpha open. 

SPACECRAFT Yes, I got H20 line heater alpha. 

CAPCOM Roger, main A open. Only alpha open. Leave bravo 

closed. 

SPACECRAFT Okay, that's accomplished. 

CAPCOM Okay, Bruce. Just want you to understand that, you 

know, while you wer 2 out EVA they got a message on this heater 
and that was because of a spike. It went back down, we had 6 

good cycles on the heaters and then they just saw another 

spike. Not enought to give you an FDA. The plan of attack on 

this one is that we're going to open A. If they still see 

spikes, the problem is in B. We'll open B and close A, over. 

SPACECRAFT Okay, we copy. Hoot's actually been the one that's 
been following that more closely and I'll pass it on to him. 

CAPCOM That's firm, thanks. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston. 

SPACECRAFT Hey, Mary, we have a lot of good video left from 
the last EVA and the one before that that we haven't dumped 
yet. However, our tape recorder has begun to eat tapes and we 
probably won't be dumping anymore for the remainder of the 
mission unless the status of that tape recorder changes. The VTR 
is on the blink it seems. 

CAPCOM Copy you're having trouble with the VTR consuming 

tapes. 

SPACECRAFT That's affirmative. 

CAPCOM And Ron, got a question for you on chat. Does it 

seem to operate okay in record? 

SPACECRAFT (Garble) been doing in the play it seems to chew 
into tape sort of creating a crease in it and eventually 
stopping. Damaged 2 tapes that way and I have not attempted 
anymoru after that. 



STS-41-B AIR/GROUND TRANSCRIPT t388j 040: 19; 49 2/9/84 PAGE 2 
CAPCOM copy that, Ron. 

SPACECRAFT Hello, Mary. You think we ought to sacrifice an 
IFM tape for this? 

CAPCOM I'll check on that for you, Ron. 

SPACECRAFT Just kidding. 

xow°? M Xt seemed appropriate to troubleshoot that with an 

H5L a ? e# challe nger, Houston. We were thinking maybe one of 
ecoms tapes may be more appropriate. 

SPACECRAFT Mary, we missed that. What kind of tapes? 

CAPCOM Roger Vance, they were thinking maybe it would be 

more appropriate to sacrifice some of ECOM's IFM procedures. 

SPACECRAFT Yes, there's an idea. 

CAPCOM And Ron, if you're still available, earlier we 

requested the footage to be used in both cinema 360 cameras and 
also the time of the GAS group echo activation this morning. 

SPACECRAFT is that the footage, you're referring to the 
rootage taken this morning, today? 

CAPCOM That's affirmative. It's a 360 footage taken 

today. 

SPACECRAFT Stand by, Mary, let me recall one. Taken so much 
footage with so many cameras today I've got to recollect this. 

CAPCOM Understand that, Ron. 

SPACECRAFT Okay, Mary, I started the day off with 1, with 2 
magazines and I now have 1 left and Hoot's figuring it out for 
me 2 minus 1. I think what we did was I got some footage of the 
EVA prep, some footage of some closeups with the 25 millimeter 
and I did a few seconds of out-the-window during the EVA just 
before night, going into day pass so I think I have about a, in a 
time magazine and a part of a partial one left, over. 

CAPCOM C 0 P V that ' R °n- They also were wondering how much 

you used in the bay camera. 

So^ CR ^ F Ln/o2^ ay ' let ' S See * First EVA 1 9<>t about 4 minutes 
worth of MFR/RMF ops. Second EVA I got about, oh, on MMU I'd say 
about 6, 7 minutes or so so total - - 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t389j 040:20:01 2/9/84 PAGE 1 

SPACECRAFT MRF RMS OPS. Second EVA got about, oh, on MMU, 

I'd say about 6, 7 minutes or so, a total, I'm estimating 
somewhere total anywhere from 10 to 12 minutes total. 

CAPCOM Okay, Ron, thanks a lot and also requested that 

they send their compliments to the photographer. And now ail we 
need is the ti.. t e for gas group echo this morning. 

SPACECRAFT Okay, I'll get those times for you, and I hope the 
end product, certainly as nice as it looks out the window here. 
And you can look up, one question for me also, I'm curious, I 
forgot, how much of the, what's the total capacity of the payload 
bay camera. How much film do we have left out there, assuming I 
used 6 minutes of it. 

CAPCOM We'll get that info for you and get back to you. 

SPACECRAFT And Houston, Challenger. 
CAPCOM Go ahead, Vance, Houston. 

SPACECRAFT Ron has got to good at running about half a dozen 
cameras systems at once, that if he ever just had one to do at a 
time, it wouldn't be enough challenge. 

CAPCOM Copy that. Hey, Vance, just a reminder from INCO, 

during your debrief, if you're going to record that, please 
verify before you start that on Panel Al, one of the voice record 
select channels rotary is turned to ICON bravo. 

SPACECRAFT Okay, ICON, roger. ICON bravo will be on one of 
the tape recorders, that's the essence of it, like the other 
night, right. 

CAPCOM That's affirm, they just wanted you to check your 

voice select channel, rotary to make sure it was being 
recorded. They really found the dump and going over it, your 
debrief really helpful. 

SPACECRAFT Okay, good, well we talked about it, and after the 
ground's suggestion that we do, we thought it was a good idea, 
because a person forgets about 50% of some of those fine points, 
a couple days later. 

CAPCOM Roger, that. 

SPACECRAFT Okay, Mary I found my checklist, and gap group, gas 
group E activation, day 5 19 + 14. 

CAPCOM Copy, 19 + 14, thanks. 

SPACECRAFT Okay. 



STS-41-B AIR/GROUND TRANSCRIPT t389j 040:20:01 2/9/84 PAGE 2 

CAPCOM And Ron, for your own information they figure you 

got approximately 2 minutes worth of cinema 360 left in your bav 
camera. J * 

SPACECRAFT That is really cutting it close, we'll get some 
earth shots I guess, we'll find some nice terrain and shoot that, 
if that's suitable. 

CAPCOM They concur and like that idea. 

SPACECRAFT Okay, Mary, I think I've got it, if we started a 
day with 2 magazines and we had 1 left, then we would have used 
one. 

CAPCOM Sounds like you'r* doing real well with this higher 

math. ^ 

SPACECRAFT Higher math for fighter pilots. 

CAPCOM I know, Bruce, you wouldn't say higher math for 

Navy fighter pilots. And Hoot, if you're still on the line, I 
got a question for you on this water dump procedure. 

SPACECRAFT Yeah Mary, go ahead. 

CAPCOM Roger, we'd like to verify that the, at 7+00 on 

R12, the supply water dump valve enable nozzle heater went on. 

SPACECRAFT Mary, something happened to my time tone, and I 
didn't turn it on. I'll turn it on now. 

CAPCOM That's fine, and we just wanted to get as much heat 

until you get to the terminator, when you commence trying to dump 
that system, not really a problem and it must have been because 
you were busy with your higher math. 

SPACECRAFT Well I knew that, yes I knew that while I was 
working on higher math, I wouldn't possibly be able to remember 
something like that, so I sat a tone on it, but it didn't go off 
for some reason. 

CAPCOM Understand no problem with it, don't worry. 

Challenger, Houston, with a question on the SPAS deactivation. 

SPACECRAFT Go ahead, I think everybody is listening, Mary. 

CAPCOM Okay, on, I know that in the flight note we said 

that you were go to deactivate the SPAS using the payload SPA 
checklist 5-2, any time after 7+00, but then payload guys would 
sort of like to see you do it. We've got about 9 more minutes in 
this -

CAPCOM Okay. I know that in the flight note we said that 

you were go to deactivate the SPAS using the payload ops 
checklist 5-2 anytime after 7 plus 00, but the payloads guys 
would sort of like to see you do it. We got about 9 more minutes 
in this TDRS pass, otherwise it'll have to wait until Guam. 

SPACECRAFT Okay, we'll go do it, Mary. 

CAPCOM Thanks, Hooter. 

SPACECRAFT (Garble) a shrimp cocktail, Hoot, if you don't qet 
back in time? 



CAPCOM And Hooter, Houston. Sorry to break into your 

appetizer like that but shrimp are high in cholesterol anyway. 

SPACECRAFT Hey Mary, is there something wrong with our supply 
water dump nozzles, nozzle heaters? I'm showinq only 29 degrees 
on those guys. 

CAPCOM Roger, Hoot, and we're looking at that data right 

now and we're checking on it for you. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston for Hoot. They think that 

there might be some sublimation out that nozzle. They're losing 
heat which is what they were trying to do to get ice out of that 
line and they want to continue with it. 

SPACECRAFT Oh, okay. So maybe that even looks promising. 

CAPCOM Well, we're hoping you're right. 

CAPCOM Challenger, Houston. We're about 40 seconds LOS 

off of TDRS and we'll talk to you again through Guam at 7 plus 



SPACECRAFT Okay Mary, see you there. 

PA0 Mission Control Houston. 6 days, 7 hours, 40 

minutes mission elapsed time. We have loss of signal through the 
tracking data relay satellite on orbit number 102. Some final 
conversations with the crew before they get into their scheduled 
sleep period in less than 20 minutes. The Payloads Officer 
reports that the crew has deactivated the shuttle pallet 
satellite and its associated experiments. Also they are seeing 
some apparent changes in the water dump nozzles on the water 
tanks believed to be frozen. They've been operating the heaters 
there and having the vehicle with the side of the vehicle exposed 
to the sun to attempt to warm that up. They've been managing the 
reduction in the water coming into those tanks from the fuel^

cells by various means such as Ubing the water spray boilers and 
they hope to be able to melt what is apparently some ice blockage 
there. That's been going on for a couple of days and the Flight 
Controller here in Mission Control responsible for those systems 
reports some apparent movement there. Again, crew has only about 
15 minutes remaining before they get into their scheduled sleep 
period. Flight Controllers here have reviewed the status of the 
systems onboard the Challenger trying to get everything squared 
away for the night. Everything seems to be goina normally 
onboard the Challenger and the crew reported just a few moments 
ago that they were eating their dinner. We'll be picking up 
again in about 16 minutes through the Guam station. It's about a 
6 minute pass. We may hear from the crew, probably be putting 
the crew to bed at that time. At 6 days, 7 hours, 43 minutes 
this is Mission Control Houston.

the off-going Flight Director with Harold Draughon has been 
cancelled. That change of shift press conference had been set at

Mission Control at the same time that Flight Director John Cox, 
was working the EVA, and we have already had the John Cox, change 
of shift press conference a couple of hours ago, and do not feel 
the need to repeat a change of shift press conference for that 
same period of time. All systems on board the Orbiter are 
quiet. The crew is about the start the scheduled sleep period, 
and there are no major problems or activities of special interest 
to discuss. To repeat the change of shift press conference with 
Flight Director Harold Draughon, originally scheduled for 
approximately 4:30 p.m. central time, has been cancelled. This 
is Mission Control Houston. 

CAPCOM Challenger, Houston, with you through Guam for 5 

minutes. 



SPACECRAFT Roger Houston, loud and clear. The vernier firing 
test is completed, and just a second and I'll aive you the time 
to look for. Mary, hot fire was completed at 7:46, 5 seconds 
pitch up, with verniers and excel. 

CAPCOM Roger, we copy that, and Vance, your temperatures 

look really good and you won't have any trouble with those 
tonight. 

SPACECRAFT Good, glad to hear did some good. 
CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead. 

CAPCOM Roger, we'll be calling you when we come AOS TDRS, 

at that time were going to update your state vector, and we 
should have a state vector that will hold good at through rev 108 
at that time. And we will also get back to you about your supply 
water, dump valve enable nozzle heater procedures and we might 
have a slight change in those from what we read up to you 
earlier. Otherwise that should be close of business for us 
today, unless you have something else you'd like us to do. 

SPACECRAFT No, I don't think so, okay we'll stand by for a, we 
won't do anything with the supply water dump until we hear from 
you and we hope we don't keep you working longer hours tonight 
like we did last night. 

CAPCOM Roger that. Challenger, Houston, we're coming on 

to LOS, we'll talk to you through TDRS at 8+24.

station. We'll reacquire through TDRS in 18 minutes. Crew is 
still going through some last minute items, finishing up there 
supper, little slower getting to bed tonight. Things are 
otherwise very quiet on board the Challenger. As a reminder the 
change of shift press conference for the off-going Flight 
Director Harold Draughon, originally scheduled for 4:30 pm today 
has been cancelled. There was a change of shift press conference 
with Flight Director John Cox, only a few hours ago, thac 
briefing covered the EVA the primary activity for today and 
encompassed the time period for most of the shift. And we don't 
feel that it's necessary to cover the additional time since that 
briefing, which has been primarily been presleep activity. 
Repeating change of shift press conference with the off-going 
Flight Director Harold Draughon originally scheduled for 4:30 pm 
central time has been cancelled. This is Mission Control

should be good to rev 108. Also 

SPACECRAFT Okay, good to rev 108 and Hoot's here's standing 
by for instructions on the water dump. 

CAPCOM Roger, what we'd like to do on that is keep that 

dump nozzle heater on. It's up to 50. We think it may be 
sublimating out and correcting the problem. However, we do not 
want that to interfere in anyway with the amount of sleep he gets 
so if he could give us a call we'll have him turn the nozzle 
heater off before he's going to sleep. 

SPACECRAFT Okay Mary, understand. We're going to go ahead 
and leave that guy turned on and then the other part of tlat was 
give you a call before we go to sleep so you can take one last 
look at it. 

CAPCOM Well, we wanted to make sure that it goes off 

before you go to sleep so that's why we'd sort of like a call. 

SPACECRAFT Okay, all right. Understood you that time. We'll 
turn it off before we go to sleep and give you a call when we do 
that. 



Roger we copy that, Vance, and we have sent a 
vector up to you to keep you going through the night and it 
"to rev 108. Also - -

Orbiter. Flight deck CRTs, 3 of the 4 are off indicating the 
crew is about ready to wrap up their night and a reminder we have 
cancelled the 4:30 pm Harold Draughon Change-of-Shi f t Briefing 
and if we follow our usual course of activity we will probably 
cancel the Larry Bourgeois briefing this evening at 12:30 am 
unless something exciting happens on the planning shift. 
Therefore, it's probable that the next Change-of-Shif t Briefing 
will be the 8:30 am Randy Stone Press Conference tomorrow 
morning. At mission elapsed time 6 days, 8 hours, 58 minutes 
this is Mission Control Houston.

Earlier this morning when the crew had awakened, 
the vernier driver that had given them some problem yesterday at 
shift handover did fail. They have gone to primaries and they're 
in with what they call the verniers fail timeline which lays out 
attitude control firings on the orbiter using primary jets rather 
than the verniers on the aft vent. And the propulsion officer 
has reported that they still have plenty of gas, even if they 
just use primaries, which are slightly less efficient than the 
verniers. At Mission Elapsed Time, 6 days 10 hours 16 minutes, 
this is Mission Control Houston. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston, go ahead. 

SPACECRAFT Hey, Guy. We just finished our debriefing of EVA 2 
ICOM B. It starts around 0850 ends at about 1025. And once 
ag?m (garble) if you could drop copies off in our office so that 
we could read them when we get back, to use during debriefing, it 
would help, we'd really appreciate it. 

CAPCOM Roger, understand you want copies dropped off in 

the office, Vance. 

SPACECRAFT Right, one for each of the five crewmen, if you 
don't mind. 1 

CAPCOM Roger, we copy that Vance and has the — have you 

turned off the supply dump valve enable nozzle heater? 

SPACECRAFT No, Guy, I have not turned that off yet, did you 
want to do one more attempt to the dump or want to just let it 
continue to sublimate, or what? 

CAPCOM we would like to let it sublimate overnight. 

SPACECRAFT Okay, copy, you want to let it sublimate, so I, I 
can turn the dump heater off anytime you want. 

CAPCOM Roger, we may as well go ahead and do it now and 

that s all we'll have and let you guys get to sleep. 

SPACECRAFT Okay, sounds good, we'll go ahead and hit her 
down there. 

CAPCOM Okay, see you in the morning, we'll have some extra 

special music for you then. 

SPACECRAFT We were hoping you would. Heck, that's what you've 
had for us all week. 



CAPCOM 



This is really special. 



STS-41-B AIR/GROUND TRANSCRIPT t394j 040;23:15 2/9/84 PAGE 2 



SPACECRAFT All right, can't wait to wake up. 

CAPCOM Mission Control Houston, Challenger now roughly at 

the equator, beginning orbit 104. Commander Vance Brand 
reporting that the crew is finished their roughly 2 hour debrief 
of today's EVA. They committed that to tape and called down some 
time numbers for that so that we can pick it out of the telemetry 
tonight and make transcripts of it for review by flight 
management and some members of the astronaut office. And Vance 
Brand asked that we dump some copies off in his office so that he 
and other members of the crew can read them when they get back. 
The other item on that transmission was concerning a balky waste 
water dump procedure. They've been having some trouble getting 
that to commit to a dump and flight director Larry Bourgeois 
asked that they just go ahead and shut the heater off and let the 
water sublimate over the night and then will try the dump again 
in the morning. 

CAPCOM ...teleprinter hooked up so we can get our stuff up 

tonight.

return link on the teleprinter. We wanted to check to make sure 
you got your teleprinter messages this morning. 

SPACECRAFT Yes, John, we faked you out on that one I'm afraid 
it should be hooked up okay now. 

CAPCOM Roger, understand and did, did you get the 

messages? 

SPACECRAFT No, we didn't. Apparently the configuration wasn't 
completely hooked up and we think it is now though. 

CAPCOM Okay, we'll get them up to you here in 10 minutes

can go ahead and take the supply water dump valve enable nozzle 
heater and turn it on and then after that gets heated up, we'll 
go with the dump. 

SPACECRAFT Okay, I've got that on.

want, I can give them to you. There's one over on the ECLS panel 
and one on — and the cryo heaters. 

SPACECRAFT I'm right next to ECLS, why don't you go ahead, 
Guy. 

CAPCOM Okay, Vance, like the 02/N2 controller #2 to close. 

SPACECRAFT Okay, it's closed. 

CAPCOM Thank you and on the cryo, we'd like the 02 and H2 

for tanks 3 and 4 all — heaters, A & B, all of those heaters to 
off. 

SPACECRAFT Okay, taking all the tank 3 and tank 4 heaters to 
off. 

CAPCOM Roger and since the 02 in tanks 1 and 2 is down 

now, you can take the bravo heaters on 02, tank 1 and 2, both of 
those to off. 

SPACECRAFT Okay, taking the 02 tank heaters and tanks 1 and 2, 
the bravo heaters, to off.

SPACECRAFT Yes, the Orbiter's all interconnected anyway. 

SPACECRAFT Bruce, could you go ahead and make a docking for 
the 360 there. 

SPACECRAFT Yes, I'm going back down. 

SPACECRAFT You have about another 30 seconds. 

Hey, Houston, you still with us? There's a dock. 

Roger, Bruce, we watched it all. 

SPACECRAFT The view isn't quite as exciting from this position 
as the (garble) one but it works. 

SPACECRAFT You're just slowly - Feels like I worked back out 
from the 1/4 inch position to the, right on the arrow. Hey, I'm 
going to try just backing off with just the jaws closed and not 
the bolt engaged to see what happens. Yes, there's your 
answer. There's a difference between the trunnion pin here on 
the SPAS and SESA trunnion pin. I'm going to turn to SESA again

SPACECRAFT Feel like I'm bumping into something. 

SPACECRAFT will it shorten the timeline if I just take the 
port MMU and - It probably wouldn't. I'd have to get the T- 
pad. Are you doffing the T-pad, Bruce? 

SPACECRAFT Yes, I'm going to swing over to the side so I can 
turn around. 

SPACECRAFT Okay. 

SPACECRAFT I didn't come in from the top since that TV camera

the rings which are located on the arms of the MMU after he has 
tethered himself here, of course, and those pull rings will 
release the latches that secure the life support system on his

SPACECRAFT Bruce, we see your sequence is MMU doff, MMU 
closeout and T-pad attached to MMU and then GN2 servicing 
starboard MMU.

p AO Mission Control Houston, 4 days, 4 hours, 23 

minutes, Mission Elapsed Time. We've had Loss of Signal thru the 
Tracking Data Relay Satellite. We'll have about a 20 minute LOS 
until we pick up over Guam. The crew was putting away the tools 
and the other items they've been using during the EVA and 
preparing to conclude the EVA just as we went LOS there, 
Astronaut Bob Stewart indicated he had a fault indication on the 
sublimator pressure reading on his EMU and he was going to move 
into the airlock to check that out. Crew has been on EMU power 
for 5 hours and 13 minutes, that's been a very long Shuttle space 
walk. They have been checking out the Manipulator Foot Restraint 
^ well as the MMUs and both astronauts conducted translations 
away from the spacecraft of distances of greater than 300 feet 
checking out those MMUs. We're at 4 days, 4 hours, 24 minutes, 
Mission Control Houston. This is Mission Control Houston 4 days, 
4 hours, 40 minutes Mission Elapsed Time. We're about 2 minutes 
away from the Guam Station. The crew should be just about 
concluded with the EVA, this first check out of the Manned 
Manuevering Units and the other specialized EVA equipment. 
During the space walk Astronaut Bruce McCandless total time in 
the MMU was about 1-1/2 hours, we don't have an exact time, but 
approximately 1-1/2 hours for Bruce McCandless in the MMU. And 
Bob Stewart's total time in the MMU was slightly more than I 
hour, about an hour and 4 or 5 minutes. The crew managed to get 
quite a number of the items for this EVA accomplished, both MMUs 
were checked out, both crewmen took thair MMUs out to the 
prescribed distance of 300 feet from the Orbiter, stabilized 
those and brought thum back. We had some check out of the 
manipulator, foot restraint, the trunion pin attachment device, 
and did some evaluation of the stability of the arm with the 
manipulator foot restraint on it. The crew, it's believed did 
not change out camera delta, the payload bay camera which has 
been giving some trouble since the first flight day. It was 
hoped we would be ,ble to crangeout that camera to get some 
better EVA view:- during the 2nd EVA, but they ran a little short 
of time and toward the end, they were told they could delete that 
changeout. Should be acquiring momentarily over the Guam 
station, this is Mission Control Houston. 

CAPCOM Challenger, Houston with you thru Guam for 5 

minutes, possible keyhole.

we pick up over the Hawaii station. Mission Specialist, Bob 
Stewart, clarifying the situation with the sublimator on his 
spacesuit, that's pare of the cooling system. Just before we 
lost signal through the tracking data relay satellite the 
previous pass, he indicated he had a high pressure alarm in the 
sublimator and he was advised by his partner in the spacewalk, 
Astronaut Bruce McCandless, to head for the airlock. He went 
through a malfunction procedure, checking out the sublimator, and 
the problem corrected itself and is functioning normally. Crew 
is concluding their EVA, still outside at the moment, but they 
are about to get back into the airlock very shortly. They have 
been on the EMU's for 5 hours and 40 minutes. During that long 
shuttle spacewalk, we had some considerable list of the items of

opportunity alignment. We would like you at the 06+20 to clear 
the star table, and ensure the trackers are in track. We're 
looking again for stars 42 and 25. You should have those at 
6+50, after you get them, we would like you to align, using thos 
stars, and copy down the numbers. Second item, is supply H20 
dump, we would like to dump tank bravo, to 30 percent, and last 
item, is we would like not to tear down the interconnect. We 
want to remain interconnected over the sleep period, over. 

SPACECRAFT Okay, Jerry, I think we copied all that 6+20, we'l 
clear the star table, put them in track. Looking for stars 
number 42 and 25, should get them at 6+50, do an align on those, 
dump supplies water tank bravo, to 30 percent, and we'll stay 
interconnected last OMS to RCS. 

CAPCOM Okay, Hooter, that's all good. One other thing is 

we want you to copy the numbers on your alignment, we won't have 
you. 

SPACECRAFT Oh, okay, sure Jerry, we'll do that. 

CAPCOM Okay, we're coming up on 10 minutes to LOS. We'll

nad a duration of 5 hours and 55 minutes. Crew has, of course, 
repressunzed the airlock and has been loading their equipment 
that they brought back in with them from the airlock into the 
middeck and proceeding to get out of their suits. The crew did 
manage to bring in the delta camera, that's one of the payload 
bay cameras, the one that had malfunctioned earlier. The color 
wheel had stuck on that camera and part of its positioning 
control was not functioning. it was hoped that that camera could 

2f,/S P ?° ed ?? that we could qst some 9° od view s of the second 
EVA during which we should have a considerable amount of 
television. Toward the end of this EVA, we pretty well 
calculated that they were not going to have time to change 
that. They were actually told to go ahead and scrub the pullinq 
of that camera. But apparently as they were about to come in, 
they did manage to have the time to take it off its bracket and 
bring it in the airlock with them. Part of its bracket will be 
switched out and it will be replaced with one of the cabin 
television cameras and that will be taken out at the start of the

so. Now it says go to post-EVA pg 5-2 in the EVA checklist. 

PAO Airlock pressure has been brought up to 

approximately cabin pressure. They're about/ready to open the 
hatch into the middeck. 

SPACECRAFT We may have to take some of this spare stuff out of 
the airlock before we can do much good. 

SPACECRAFT Ok, 02 actuator off. 

SPACECRAFT No wait a minute, we've got to get some of this 
clutter out before we get to that. Bob's SCU has come off. Ok, 
Vance, here comes a camera. Vance?

PAO and the problem corrected itself and is functioning 

normally. Crew is concluding their EVA, still outside at the 
moment, but they are about to get back into the airlock, very 
shortly. They have been on the EMU's for 5 hours and 40 
minutes. During that long shuttle spacewalk, we had some 
considerable, considerable list of the items planned, 
accomplished. Including the first checkout of the man 
maneuvering units, in which the astronauts in there spacesuits, 
with the EMU's attached, moved away at distances of greater than 
300 feet from the Orbiter, not connected with any tether or any 
restraint of any kind. In affect, becomming individual 
spacecrafts of their own. The first time, a spacewalk has every 
been accomplished without the crewman being attached, by a 
lifeline or a tether of some kind, to the parent spacecraft. 
Also, checked out on that during this spacewalk, was the 
manipulator foot restraint, and the trunion pin attachement 
device two important pieces of equipment in future working in 
space, particularly in space construction and servicing of 
satellites and other equipment in space. Much of the work done 
here today, leads up to the servicing operations and repair of 
the solar maximum satellite on the next space shuttle mission, in 
April in which the shuttle rendezvous, with a malfunctioning 
scientific satellite, that has been orbit since 1980. Make some 
repairs to an electronics box, so that the satellite can control 
it's attitude, and perform it's mission properly. The EVA on 
Thursday, will include additional use of the MMU, and the dockrng 
with the rotating shuttle pallet satellite on the end of the 
mechanical arm, to simulate the docking with the solar maximum 
satellite to take place on the April flight. We're about 3 
minutes away from picking up over the Hawaii station. This is 
Mission Control at 4 days, 4 hours, 52 minutes into the flight. 

SPACECRAFT Okay, it's closed. 1 second. Okay airlock, 
depress valve is closed. Okay. IV 1 set comm to PTT, we're 
going to either go PTT or vox depending on how bad it gets and 
Vance?. IV 1. Go ahead. Innner hatch equalization valve, 1 of 
them open to normal please. Okay. 

CAPCOM Challenger, Houston, with you at Hawaii for another 

h and 1/2. 

SPACECRAFT Okay, Jerry, We got the valve clear and we're just 
r<=» . •: ssing the airlock now. 

C/.PCOM Okay, good show. 

SPACECRAFT The airlock pressure is fine, close the valve. 
Close the equalization valve. It's off. Okay, we're going to do 
a pressure integrity check here, For 2 minutes, I'm reading 5.7, 
you want to time 2 minutes, Vance. Oh, this watch works now. 
Now that we wounu it. Yean, I can start it if you wish. Go 
ahead. (garble) good status. Okay, disconnect waste areas, and 



STS-41-B AIR/GROUND TRANSCRIPT t252j 038:19:34 02/07/84 PAGE 1 



SPACECRAFT - - think by switching Bruce and Bob on comm modes 

as recommended, the third thing was Bob's foot restraint. Bob 
did not try out the airlock foot restraint, while he was 
pressurized mainly because they were kind of in a hurry to get 
in, but once he was unpressur ized we made a an unpressur ized 
comparison of boots in the airlock foot restraint. And I think 
Bob has a few words on how much bigger his toe is than Bruce's, 
in that, as far as the boots concerned. And after we get done 
eating, why we'll go ahead and have a debriefing. We intend to 
do it on intercom, we can do it on intercom B, if you wish, and 
we'll probably do it on our own little tape recorders too. 

CAPCOM Understand, Vance. 

SPACECRAFT Mary, this is Bob now. I'd like to just tell you 
about that (garble) problem because I've got (garble), get some 
somebody some lead time to work on it before the next EVA. It is 
a tongue hiest problem. It's very hard, almost impossible to 
wedge my toe far enough into the foot restraint to rotate the 
heel under the lock. The heel has a little bit of clearance not 
nearly as much Bruce' s boot, but the toe is the significant 
problem, mine is wedged in there before I get the heel in 
contact. Bruce can lock his heels, and still have clearance 
under the toebar. 



CAPCOM Roger we copy that, Bobby. 

SPACECRAFT And that was unpressur ized, so the pressure is just 
going to make it worse. 

CAPCOM Understand that was unpressur ized. And Challenger, 

Houston, was, payload was wondering how v ,he A EM OPS went at 4+30? 

SPACECRAFT Mary, you were cut out by some interference, please 
repeat. 

CAPCOM Saying again, payloads was wondering how the AEM 

OPS went that was suppose to occur at 4+30 per the CAP? 

SPACECRAFT Stand by. Yeah. Mary, Ron's changing batteries, 
on his headset, the wireless, and he'll be up with you in just a 
second . 



CAPCOM Okay, we're 50 seconds LOS Hawaii, we'll drop you 

for a couple of minutes, and pick you op through TDRS. So we 
might want to wait until then. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston, back with you through TDRS. 



SPACECRAFT 



Okay. Roger, we have you, Mary. 



STS-41-B AIR/GROUND TRANSCRIPT t252j 038:19:34 02/07/84 PAGE 2 

SPACECRAFT Houston, Challenger. 

CAPCOM Go ahead, Challenger, Houston. 

SPACECRAFT Roger, Mary, wanted to give you some words on the 
AEM, I did not turn the lights, I did not turn the lights off 
until after the EVA. I noted before flight that was not listed 
in the EVA checklist and somehow it never got in there, so I 
didn't see it until after the EVA was over. I did turn the 
lights off, but I was unable to get data because we had EVA 
equipment stowed in front of the locker, and I was not ready to 
disturb it at that time. I do plan to take some data, within the 
next 1/2 hour or so. But the lights got off maybe an hour and 
1/2 late. 

CAPCOM Copy that, and understand, the reason we asked was 

because it seemed to be buried in the CAP there. 

SPACECRAFT Exactly right, it's in the CAP, and not in the EVA 
checklist, and it just won't get seen that way. 

CAPCOM Roger, copy. 

SPACECRAFT Mary, if it had been in the checklist, I'm not sure 
Ron would have had time to do it or any of the rest of us, Ron 
busy rUnnin9 RMS probablv about tnat time ' and we we're really 

CAPCOM Roger, understand. Challenger, Houston, have 

another question for Ron. 

SPACECRAFT Go ahead. 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t253j 038:19:44 2/7/84 PAGE 1 

CAPCOM Roger, understand. Challenger, Houston, hav 

another question for Ron. 

SPACECRAFT Go ahead, M 

CAPCOM Roger, y sported early in the EVA that that 

video record button was ck and we were wondering whether the 
power cycle recovered it or whether you had to do somethinq else 
to get it back. y 

SPACECRAFT No, Mary, that turned out to be a configuration 
problem. We checked the configuration and we had to get the VTR 
play set to the monitor, somehow we changed tapes it got shut off 
and we found that and corrected the problem. 

CAPCOM Ok, thanks, understand that. Also, just a reminder 

for, on your setup to record ICOM B. That in order to get that, 
make sure on panel Al that one of you voice record roteries is 
selected to ICOM B. 

SPACECRAFT Ok, Mary, we copy that. 

CAPCOM Challenger, Houston, have a few question about the 

EVA today that we would like to get answered before we leave you 
alone for the evening. 

SPACECRAFT Ok, stand by, EVA crewmen are getting on the line. 
CAPCOM Ok, thanks, Vance. 

SPACECRAFT If you've got anything specifically for Bob, Mary, 
I can answer you right now. 

CAPCOM ok, thanks, Bob, I sure do. with the secondary 

TPAD anomaly, they would like you to give them some more 
information on what happened when you were lowering that 
secondary TPAD. 

SPACECRAFT Ok, one of the times that fit into lock (garble) 
secondary TPAD in place was too long when I tried to rotate the 
TPAD back down and it all the other times cleared, except that 
one and it was catching on the TPAD itself. I tried several 
different times to sort of force it past, and 1 was relocking it 
and then trying to accelerate the TPAD down an -;hen hopefully it 
would just kind of (garble), None of that worked and so I went 
and got the tools which are fortunately stowed right beside it 
there and twisted that particular time in until it just cleared 
the lip on the secondary TPAD and from that point, it rotated on 
down. 



CAPCOM 



Roger, Bob, what tool did you use to rotate it? 



STS-41-B AIR/GROUND TRANSCRIPT t253j 038:19:44 2/7/84 PAGE 2 



SPACECRAFT Say that again, Mary. 

CAPCOM Bob, they were wondering specifically what tool you 

used. 1 

SPACECRAFT There are 2 wenches stored on the door of the SESA, 
and they just happened to fit the size on the TPAD. 

CAPCOM Roger, copy, thanks. Also, they were wondering 

whether you had trouble with all the foot restraints in the bay, 
or whether it was one particular one. 

SPACECRAFT No, it was all of them. As soon as I could get 
into the MSR foot restraints, it was a little bit easier, no 
excuse me, not the MSR, the SSS foot restraints a little bit 
easier then the others, but the SESA foot restraint was almost 
impossible for me to get into. As was the Manipulator Foot 
Restraints. I don't think I would have been able to board the 
MFR, just between you and me, I didn't really get a chance to try 
it. When I deployed the stantion on the MFR, to put the tools 
onboard, I tried to get into the foot restraints down there and 
it was turning into a hassle and so I just stowed the, no I did 
finaly get them in there, yes, I did and I did stow the tools 
from that position, but it was a real chore to get my boots in 
there. 

CAPCOM Copy that, thanks. 

SPACECRAFT And Mary, my initial impression was if it was paint 
problem, like we'd seen before, but when I tried to get into the 
unpainted foot restraints on the CPSA, I had the same problem I 
had on the SESA, so it's pretty much been around the ship, 
problem with pro-heights. 

CAPCOM Ok, we copy. Also Bob, we have a request that you 

give us a time hack when you start your debriefings so we'll know 
when to recover that debriefing off the ICOM. 

SPACECRAFT Ok, we'll do that. 

CAPCOM And that's all the debriefing we need from you now, 

and the only other question is for Bruce. Thanks a lot. 

SPACECRAFT Ok, Bruce is online right now. 



CAPCOM 



Evening, Bruce. We have 1 question for you 



SPACECRAFT (garble) Mary, I'm on hardline. We still have a 
lot of noise but go ahead. 

CAPCOM Roger, we'd like to know on your force evaluation 

test, stand by. END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t254j 038:19:51 2/7/84 PAGE 1 

CAPCOM Roger, we'd like to know on your force evaluation 

test, stand by. Roger, Bruce, on the force evaluation test, we'd 
like to know if there was any difference between position hold 
and the brakes when you ran that test? 

SPACECRAFT Yeah, it felt to me like in the brake mode I could 
definitely feel it drift (garble) from the position hold I 
couldn't feel (garble). 

CAPCOM Challenger, Houston, Bruce, you're unreadable, 

there is an awful lot of background noise in your transmission. 

SPACECRAFT Okay, Mary, what Bruce »s comment was that in 
position hold, well let me back up, in brakes on, he could feel a 
discrete slip to the arm. He definitely felt the time when it 
would go. In position hold, the point in which it slipped was 
always called by Ron, looking at his digital display, seeinq a 
slip of greater than .2 degrees. y 

CAPCOM Roger, copy. 

SPACECRAFT How's this, is this better? 

CAPCOM Much better, Bruce, you're loud and clear. 

SPACECRAFT Yeah, Mary, as far as stiffness goes, they seem 
about the same, that is the arm itself deflected about the same, 
it was just that in brake mode, when it let go, you could feel a 
sort of a roughness or a vibration, as it moved, in fact, I was 
very surprised that the surge of things you could feel. In the 
MFR, out there at the MEB task, I could feel the vibrations, 
arising from Bob putting his 35 foot tending, soft tending tether 
reel over the hook on the MMU FSS, and things like that. I 
really hadn't thought I would be able to feel things like that. 

Roger, copy. I have one more question, for Bob on 



CAPCOM 
the T-pad. 



SPACECRAFT Yeah, get it back to Bob here. 
SPACECRAFT Go ahead, Mary. 

CAPCOM Roger, the guys down here were wondering whether 

you would consider the T-pad usable for the EVA tomorrow. 

SPACECRAFT Sure, I'd use it, I'd consider it usable. (garble) 
would probably be usable, it was just a little bit of a clearance 
problem, Mary, I think it's taken care of now. 



CAPCOM 



Okay, thanks, that sounds real good. 



STS-41-B AIR/GROUND TRANSCRIPT t254j 038:19:51 2/7/84 PAGE 2 



SPACECRAFT Bruce points out that it's not tomorrow for the 
EVA, and in any case, we planned to use the primary T-pad on the 
SPAS docking, so the points is kind of a moot point I guess. 

CAPCOM Roger, copy. 

SPACECRAFT Mary, Challenger. 

CAPCOM Go ahead, Vance. 

SPACECRAFT Mary, now that we have our alignment, we know where 
to go back to -ZLV at 8+15, is there some particular reason for 
holding off till then? We noticed an - attitude we're currently 
in. 1 

CAPCOM We're checking. Challenger, Houston. Vance, 

there's a low g-period between 705 to 805 that they are tryinq to 
work around, and also GN&C would like the alignment data if 
you've got it. Challenger, Houston 

SPACECRAFT Yes. 

CAPCOM Roger, Vance, I'm sorry we had a comm drop out 

then, I'll repeat that the, between 705 and 805, there is a low 
g-period for the heat pipes experiment, and they are tryinq to 
work around that. 

SPACECRAFT Okay, well that's fine, we'll start at 8+15. 

CAPCOM And Vance, we're standing by to copy the alignment 

numbers when you've got them. 

SPACECRAFT Okay, Mary, if you're ready. 

CAPCOM Ready to copy. 

SPACECRAFT Okay, they were stars 42 and 25, angle area 0.01, 
and I'll read across all the delta X's. -0.09, -0.21, -0.01, all

SPACECRAFT Okay, great thanks. 
CAPCOM Sure thing. 

CAPCOM Challenger, Houston. Have one more presleep 

activity for you. 

SPACECRAFT Okay, go ahead Mary. 

CAPCOM Roger. Has to do with a 10.2 psi cabin 

maintenance. We'd like to get about 0.2 psi more pumped in, of 
the N2 pumped into the system so on MO 10 whiskey, we'd like you 
to take the 14.7 cabin reg inlet system 1 valve open to get the 
N2. And then also, we'd like you to verify, since we're not sure 
where it is, that the PP02 hardware limits that's on alpha 
channel 34 upper caution warning limit is 3.20 psi, and that the 
PP02 bravo, which is channel 42, is 3.10 psi and we'll TMBU the 
software. Over. 

SPACECRAFT Okay, Mary. We copy that you wanted 34 to be 
3.2. I think the other one you meant was 44 to be 3.1? 

CAPCOM Your right, I'm wrong. Sorry about that. And 

that's a good readback. 

SPACECRAFT Okay and then Mary the other part of it was, you 
want us to pump cabin press about .2 psi more. We're at 10.3 
right now. Do you want us to run it to 10.5? 

CAPCOM That's affirmative. 

SPACECRAFT Okay, we'll do that and we'll do it by opening 
system 1 to flow into. 

CAPCOM Okay, that's good. 

SPACECRAFT (garble) to put in tape over there Ron?

. This is Mission Control Houston at 4 days, 7 hours, 

14 minutes mission elasped time. The crew is going through the 
final preparations before their scheduled sleep period. They 
have completed a fuel cell purge and setting up the other Orbiter 
systems for the night. Flight Controllers here in Mission 
Control are reviewing any last minute items to give to the crew 
before their sleep period begins in an hour and 45 minutes. 
Things are very quiet here in the Mission Control Center after a 
very busy day of EVA activities. Very successful EVA in which 
quite a bit of work was done testing out the MMU's and many new 
tools to be added to the shuttles' capability. We have about 20 
minutes remaining in this tracking data relay satellite pass, but 
we don t expect too much communication with the crew as the 
Flight Controllers are trying to leave them alone and let them qo 
through and have their evening meal and make their other 
preparations for sleep tonight. This is Mission Control.

is any communication necessary with the crew. Most of the items 
have been finished up for the day. A few housekeeping type 
things, fuel cell purges, IMU alignments, that sort of thing 
being handled by the crew as they prepare and consume their 
evening meal. They're in the scheduled pre-sleep period and have 
about an hour and 20 minutes before they're due to go to sleep 
for the night. Shouldn't be much further communciation with them 
this evening by Mission Control because most of the items have 
been read up to them already.

SPACECRAFT Mary, this thing kind of looked like a dark in 
space, of a big store after a real good sale. It had things 
scattered all over the place. It's starting to look pretty ship 
shape now. 

CAPCOM Roger, copy. 

PA0 Mission Control Houston, standing by for 

acquisition through the tracking data relay satellite, repeating 
that the change of shift press conference with the Flight 
Director Harold Draughon, previously scheduled for 4:30 has been 
cancelled. All of the activities during the day were covered 
during the change of shift press conference, which occurred at 
1:30 with Harold, with Jon Cox. Challenger is on orbit number 
70. The crew is configuration the spacecraft for sleep period, 
they've already turned off a couple of the CRT's, just about all 
of the items change out of the lithium hydroxide canister, water 
dumps, fuel cell purges, IMU alignments and all of that, have 
been taken care of for the evening. Crew due to begin their 
scheduled sleep period in 41 minutes. So we may have little or 
no communication with them before they go to sleep. 4 days, 8 
hours, 18 minutes. This is Mission Control Houston, 

CAPCOM Challenger, Houston, back with you through TDRS 

now. 



SPACECRAFT Okay. Hey, Houston, loud and clear. 
CAPCOM Got you loud and clear too, Vance. 

SPACECRAFT Houston, Challenger, with a radio check on the hand 
held mike, how do you read me? 

CAPCOM Read you loud and clear, on the hand held mike, how 

me? 



SPACECRAFT Okay, we got you the same, thanks, Mary. 
CAPCOM Welcome, Hooter. 

PA0 Mission Control Houston, now approximately 1 1/2 

million miles into the 4th flight of the Challenger. The crew is 
about to go to sleep, with approximately 1/2 hour left in their 
sleep shift, we would remind you that the change of shift 
briefing, originally scheduled for 4:30 p.m. has been 
cancelled. Here in the Mission Control Center, the planning team 
is going through their hand over procedure. Orbiter Challenger

CAPCOM Challenger, I know its sleep time now, I've got a 

couple of questions for you. 

SPACECRAFT Challenger, were you calling? 

CAPCOM Roger, Hoot, I've got a couple of notes here for 

you if you can listen. Challenger, Houston, how do you read? 
Challenger, Houston, how do you read? 

SPACECRAFT Hello, Houston, we're reading you, how do you read 
us? 

CAPCOM Loud and clear now, Hoot, we were dropping in and 

cut of TDRS. I know it's bed time, but I've got a couple of 
notes for you. One, we're going to send up the camera changeout 
IFM note here over Guam, just in case somebodies up and wants to 
read it, otherwise you'll have it in the morning. And your state 
vector right now is good for about 3 revs, we're going to uplink 
a new vector for you in 1 or 2 revs that will last you till PLS 
tomor row. 

SPACECRAFT Ok, good deal. 

CAPCOM Rog, and if you guys have finished debriefing the 

EVA, we'd like to get the ICOM B, debrief time so that we can 
look at that tonight. 

SPACECRAFT Ok, they are still debriefing and that's where it's 
going, it's going on ICOM B which, of course, is channel 2, but 
they haven't finished yet. How about if I give you buz when 
they're all done? 

CAPCOM Sounds good, we'll be here. And we're LOS TDRS in 

about 8 minutes and we'll have Guam in about 26 minutes at 9+30. 

SPACECRAFT Ok, and in case I forget to tell you, the MET that 
they started the debreif was 20:35, or wait a minute make that 
08:35. 

CAPCOM Roger, copy, 08:35 for the start, thanks, and if 

we're not with you when your finished, you guys can go to bed, w<* 
can figure out where the end of it is by listening to the start. 

SPACECRAFT Ok, all right, we'll do it.

PA0 Mission Control, Houston. The data processing 

systems officer reports that one of the CRTs on the flight deck 
of Challenger has been turned on, CRT #4. And flight director 
Richard Fitts and Larry Bourgeois verified that there have been 
no alarms or any reason that the crew might have awaken other 
than someone is just up prowling about. We're on orbit 73 and

PA0 Mission Control, Houston. Orbiter Challenger now 

over the Indian subcontinent on orbit 74. We've entered one of 
those 40 minute TDRS to TDRS loss of signal periods where we'll 
travel without benefit of ground station coverage until we 
acquire signal through TDRS in about 40 minutes. All quiet 
aboard the Orbiter and in Mission Control. The mission summary 
and CAP updates for tomorrow are now being approved and put 
together and should be uplinked to the crew shortly. Awake time 
is m 2 hours, 56 minutes and mission elapsed time is 4 days, 14 
hours, 3 minutes. This is Mission Control, Houston. 

PA0 Mission Control, Houston. We've got an update on 

an Orbiter sighting for the Houston area for tomorrow morning for 
those of you listening in the Houston area. The Orbiter will be 
visible at about 5:54 a.m. central time coming in out of the 
southwest at an azimuth of 219 degrees and a maximum elevation of 
57 degrees. Again the pickup time for that Orbiter sighting is 
approximately 5:54 a.m. central at an azimuth of 219 degrees, or 
out of the southwest, and it will reach — it's highest elevation 
will be 57 degrees and should be visible for about 4 and 1/2 
minutes. At mission elapsed time, 4 days, 14 hours, 14 minutes, 
this is Mission Control, Houston. 

PA0 Mission Control, Houston. We've got yet another 

update on the Orbiter pass over Houston tomorrow morning, 
February 8. The numbers changed slightly. The time of closest 
approach is 5:55 a.m. CST, highest elevation 62 degrees, the 
azimuth 173 degrees so almost due south and that time that we 
would see it is 20 seconds after Orbiter sunrise or about 20 
seconds after the sun strikes the vehicle so it should be nice 
and bright. Latest weather update, we're told here in Mission 
Control is locally, high, scattered clouds, if that. So it 
should be a good sighting opportunity. Those times again, 5:55 
a.m. CST, elevation 62 degrees, azimuth 173 degrees. At mission 
elapsed time, 4 days, 15 hours, 2 minutes, this is Mission 
Control, Houston.

PAO This is Mission Control, Houston. The change-of- 

shift briefing scheduled for this morning with Flight Director 
Larry Bourgeois has cancelled. The crew's sleep period is just 
now expiring onboard Challenger. No indication of any CRT 
activity on the vehicle yet. Doubtful that there'll be any 
uplink communication from the control center, although we are 
within range of TDRS. But following the pattern that the 
CAPCOM's have established over the past several days, we would 
expect the initial wakeup call to be over Yarragadee, which 
occurs in about 24 min. Mission Elapsed Time is 4 days, 17 hr 
even. Again, the change-of-shif t briefing with Flight 
DirectorLarry Bourgeois, scheduled for 12:30 a.m. Central 
Standard Time is cancelled. 

PA0 This is Mission Control, Houston. CRT number 1, 

the cathode ray display directly in front of the commander's 
position in the flightdeck has been activated, indicating that at 
least someone's awake onboard the flightdeck of Challenger. 
Mission Elapsed Time, 4 days, 17 hr, 2 min, this is Mission 
Control, Houston. 

PA0 This is Mission Control, Houston. We're out of 

range of the TDRS satellite now, and we'll acquire through 
Yarragadee in 13 min. As expected, no dialog even though there 
are indications that the crew's awake, and they're moving around 
going about their business of getting ready for the day's 
activities as shown by some data reviewing activity on the 
cathode ray tube displays in the flightdeck. Handover has 
occurred in the Mission Control Center. Flight Director Randy 
Stone and the Orbit 2 team of flight controllers has inherited 
responsibility for the mission from Larry Bourgeois on the 
planning team. The change-of-shif t debriefing makes the point of 
the Orbiter being remarkably free of systems problems. The other 
events of this mission, perhaps, overshadowing the fact that the 
Challenger is providing a rock solid performance during this 
flight, and repeatedly as the flight director went around the 
room to get status reports from the individual flight 
controllers, he was advised that no system problems exist in the 
various specialties represented here in the control center. So 
Challenger providing yoeman service to the crew of Mission 41B. 
We'll acquire signal, voice only, through Yarragadee in 12 min. 
The duration of that Yarragadee AOS will be about 7 min, at 
Mission Elapsed Time, 4 days, 17 hr, 13 min. This is Mission 
Control, Houston.

Wake up Music 

CAPCOM Good morning, Challenger. 

SPACECRAFT Good morning Houston, things going well up here. 
How down there? 

CAPCOM Roger, good morning, Ron. John and I are standing 

here. John's got a shirt on that says, NCA&T State University 
and I've got a hat on that says A&T Aggies. 

SPACECRAFT Hey fantastic. I thought I recognized that 
music. The words were a little strange but the melody came 
through. 

CAPCOM Good . 

SPACECRAFT Hey that's great stuff. 

CAPCOM Roger that, second half of that was "Southern to 

the Top." And Challenger, Houston, just a reminder in case you 
haven't got your CAP updated yet. We've got a maneuver to an IMU 
align here in about 8 minutes from now if you could check that. 

SPACECRAFT Okay Guy, we'll have that set up for (garble) 
maneuver . 

CAPCOM Roger, thank you. 

PA0 This is Mission Control, Houston. We're at LOS 

Yarragadee and passing through a brief gap in coverage. A minute 
and a half before we pick up voice and data through Orroral and 
we'll have Orroral for about 4 and 1/2 minutes. Wake up calls 
were the North Carolina A&T University alma mater of which 
Mission Specialist Ron McNair is an alumnus and "Southern to the 
Top", the fight song from the University of Southern Mississippi, 
the alma mater of Mission Specialist Bob Stewart. Mission 
elapsed time is 4 days, 17 hours, 32 minutes. We are about a 
half a minute away from AOS, this is Mission Control, Houston. 

CAPCOM Challenger, Houston, we're going LOS here at 

Orroral in 30 seconds. We'll see you TDRS at 17 plus 54, 15 
minutes .

CAPCOM - - 30 sec. We'll see you TDRS at 17 plus 54, 15 

min. 

PAO This is Mission Control, Houston. Got some 

downlink television due during this next TDRS pass. That'll 
occur at Mission Elapsed Time 4 days, 17 hr, 58 min, translating 
into approximately 12:58 a.m. Central Standard Time. It'll be 
payload bay scenes of the Mass Spectrometer in the payload bay. 
When Mission Specialist Bruce McCandless did some repairs on that 
unit during yesterday's EVA, he effectively got it working again, 
but there is apparently some sensor damage in there that makes it 
impossible for the ground payload 's people to tell when that 
spectrometer is swivelling, so they're going to look at some TV 
of it, watch it swivel, and then correlate data to what they're 
able to see visually occurring with that experiment. That 
downlink TV, again, due at Mission Elapsed Time 4 days, 17 hr, 58 
min, or 12:58 a.m. Central Standard Time. Presently, Mission 
Elapsed Time 4 days, 17 hr, 46 min. We'll have acquisition 
through TDRS in less than 8 min. This is Mission Control, 
Houston. 

PAO This is Mission Control, Houston. We're just 

seconds away from acquisition through TDRS, and the downlink 
TV. TV will probably very brief. It's just to give the 
payload 's people an opportunity to position the Mass Spectrometer 
swivel mechanism, and we should have a blockage of the Ku-band 
antenna fairly early to the Orbiter's attitude, so it should be a 
fairly brief TV downlink. We'll get voice momentarily through 
TDRS. Mission Elapsed Time, 4 days, 17 hr, 55 min. This is 
Mission Control, Houston. 

CAPCOM Challenger, Houston is with ycu through TDRS, and I 

have two things for you. 

PAO This is Mission Control, Houston. Challenger right 

now is pointed for an IMU alignment, navigational aid alignment 
that's looking at a couple of specific stars, and at this 
pointing angle. The satellite is only about, between 12 and 15 
deg off the nose of the vehicle, which is not a very good look 
angle for the Ku-band antenna mounted on the forward starboard 
side of the payload bay doors, and accordingly, we're just not 
getting a good forward link right now, and this position should 
improve gradually here, and we should have voice before much 
longer. Mission Elapsed Time, 4 days, 17 hr, 58 min, this is 
Mission Control, Houston. 

CAPCOM Challnger, Houston. Radio check. 



PAO This is Mission Control, Houston. We're still 

having that pointing problem. The - -

Bermuda for 12 min. 

CAPCOM Challenger, Houston is with you through MILA 

Bermuda for 12 min. 

SPACECRAFT Roger, Houston. We're working with the last marks 
right now. 

CAPCOM Roger, and Vance, we'd like ya'll to do two things 

for us. One, we'd like you to turn off the yaw sensor, please, 
and secondly, just for your information, INCO is taking camera 
alpha to do some mass spec positioning. 

SPACECRAFT Okay. Yaw sensor off, and roger, camera alpha. 

SPACECRAFT And, John, was — in the CAP where it says check 
yaw sensor. Does that mean turn the yaw sensor off? 

CAPCOM Roger. It does, Hooter, and we'll make it say yaw 

sensor off in future updates. 

SPACECRAFT Okay. All right, cause we looked at that, and we 
had turned it on last night, and we assumed that check yaw sensor 
means it's still going, so we - - 

END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t265j 039:07:10 2/8/84 PAGE 1 

SPACECRAFT ... check yaw sensor. Does that mean turn the yaw 
sensor off? 

CAPCOM Roger, it does, Hooter, and we'll make it say yaw 

sensor off in future updates. 

SPACECRAFT Okay, alright because we looked at that and we had 
turned it on last night and we assumed that check yaw sensor 
means it's still going so we had checked it still going. And I 
guess the printed copy of the CAP had the same sort of 
terminology so check or turn yaw sensor off would probably be a 
better way. 

CAPCOM Roger, I understand. I made the same comment when 

I came in this morning. 

SPACECRAFT Must be great minds working away. 
CAPCOM Roger. 

CAPCOM Challenger, Houston, if you could turn the forward 

payload bay lights on for us, please. 

SPACECRAFT Okay John, we copy that. 

This is Mission Control, Houston. The payload bay 
lights or flood lights will now be coming on to facilitate a view 
of the mass spectrometer on the shuttle pallet satellite so that 
the payloads officers can do some positioning. Mass spectrometer 
is moving in the center of the screen there. This is Mission 
Control, Houston, the payloads officer reports that that motion 
we witnessed early in the TV was the positioning function and 
that the mass spectrometer is now properly positioned for the 
data take that they wish to accomplish. 

CAPCOM Challenger, Houston, I have something I want you to 

do, reference your PP02 message when you have a minute. 

SPACECRAFT Okay, go ahead John. 

CAPCOM Roger, the cabin PP02 has been running slightly 

high during the 10.2 Ops so we would like to shut off the 02 flow 
into the cabin from the bleed orifice until the PP02 gets back 
down to normal around 2.7 psi. To do that, the switch you have 
to do is down on M032 mike and on that panel, it's the LEH02 
toggle valve #5 to close. 

SPACECRAFT Okay John, that's complete. 



SPACECRAFT We can try that. Increase the respiration rates up 
here too, John. 



STS-41-B AIR/GROUND TRANSCRIPT t265j 039:07:10 2/8/84 PAGE 2 
CAPCOM Roger that, Vance. 

SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead Vance. 

SPACECRAFT Okay, performed another star count, star 12. I can 
read vou some bias numbers, if you'd like. 

CAPCOM Okay, ready to listen. 

SPACECRAFT .44, .42, .59, .46, .55, .81. Over. 

CAPCOM Roger, we copy, thanks a lot, Vance. 

SPACECRAFT And we had that star until 18 after the hour. We 
were to start the maneuver at 10 after. The two were 
incompatible since we really didn't get started til after the IMU 
align. So anyway, the maneuver was a little late. 

CAPCOM Roger, and that's okay, Vance. Looked good to us. 

SPACECRAFT And I took down the COAS, checked the bottom of it, 
and the mounting, reinstalled it and I didn't notice any ... 

CAPCOM Okay, understand, you didn't notice anything and 

Vance if you have a second and can give us the IMU align data, we 
would take it from you. 

SPACECRAFT Okay, stars 12 and 31, angular error .02; delta X 
going across -.01, -.16, +.01; delta y +.19, +.01, +.07, delta Z 
+.12, -.08, -.11; execution time 4/17:51:10. 

CAPCOM Roger, we have all the data and we're finished with 

the payload bay now if someone wants to go ahead and turn those 
lights off there. That's okay with us.

CAPCOM Roger, we have all the data and we're finished with 

the payload bay now if someone wants to go ahead and turn those 
lights off there. That's okay with us. 

SPACECRAFT Okay, I'll turn them off. 

CAPCOM Challenger, Houston, I have a message for Bruce. 

SPACECRAFT Okay John. 

CAPCOM Roger, the EVA folks want you to know that they see 

the MU batteries fully charged and you're go to continue. 

SPACECRAFT Okay, we got the airlock all buttoned up right now 
so when we get the airlock open, we'll check the air meters also 
and then shift over charging the MMU batteries. But it's a good 
call, thank you sir. 

CAPCOM Roger and you can do it at your convenience, Bruce. 

SPACECRAFT Thank you. 

CAPCOM Challenger, Houston, I hate to bother you again. 

But if somebody can give us a SPEC 1 on a GNC machine for 
variable parameter, we'd appreciate it. 

SPACECRAFT Okay Houston, you have it, CRT1. 

CAPCOM Thanks a lot Vance. And Challenger, Houston, the 

CRT in yours, #1, thanks a lot. 

SPACECRAFT Roger. Hey Houston, Challenger, are you still with 
us? 



CAPCOM Roger, go ahead, Bruce. 

SPACECRAFT John, one of our communications problems seems to 
be that the middeck audio center is virtually useless from an 
ICOM standpoint. Lots of noise and when I'm hooked in there with 
the wireless cornm unit, it's virtually, it's impossible to read 
you guys. What we'd like to suggest later on today if you agree, 
is reconfiguring the teleprinter so that the teleprinter runs off 
that middeck station. We can recieve you all very nicely on the 
speaker box and things like that and if you concur , we would 
rerig the teleprinter later on today and ask you for test a 
message. And if that works out, that would restore us to 4 
active, well, 4 usuable audio centers. That is the 4 up here in 
the flight deck. Right now, we're running 3 wireless comm units 
on one splitter box up here, then two singles, over. 



STS-41-B AIR/GROUND TRANSCRIPT t266j 039:07:26 2/8/84 PAGE 2 

CAPCOM Roger, we copy all that Bruce and we'll have INCO 

look at it and get back to you later today on that. 

SPACECRAFT Okay, mighty fine. 

CAPCOM Roger, sounds like a good idea that might work. 

We 1 11 get back to you. 

SPACECRAFT Houston, Challenger. 

CAPCOM Roger, go ahead. 

SPACECRAFT Yes, John, I can give you guys an update on that 

Cinema 360, footage yesterday that we took during the EVA. 

CAPCOM Roger, we're ready to copy, Ron. 

SPACECRAFT Okay, we initially rolled about 45 seconds of MF — 
Bruce on the end of the MFR, this was sort of over the port 
longeron at the time. We ran out that footage just to be sure 
that the dome worked and the camera worked, that we're in good 
configuration so that when we're ready to really trim the prime 
shot, we wouldn't have problems starting the system. It worked 
fine then. The next time we tried it, we ran about 3 minutes 
worth. This was Bruce essentially on top of the GAS can with the 
Cinema 360 and we ... on the MFR again. And we got some very 
nice footage of him passing the GAS canister containing the 
MFR. So totally, we got about 4 minutes worth. All of it was 
MFR and we could — also probably Bob at the port MMU was in the 
field of view as well. Over. 

CAPCOM Roger, we copied all of that Ron, thanks a lot. 

SPACECRAFT Oaky, and I thank you guys for that, that wake up 
music this morning and the A&T coverage, that's a great place and 
I appreciate that. 

CAPCOM Roger that, Ron, we enjoyed doing it for you. 

CAPCOM Challenger, Houston, we're going LOS. TDRS in 

about a minute, we'll see you at Yarragadee at 18 plus 59 in 
about 13 minutes.

SPACECRAFT Okay, John. We'll talk to you there. 

PAO This is Mission Control, Houston. We're LOS 

through the TDRS system. We'll pick up Yarragadee in we'll 

pick up Yarragadee in about 10 min, and that'll be a fairly long 
AOS through Yarragadee of a little over 8 min. Mission Elapsed 
Time, 4 days, 18 hr , 49 min. This is Mission Control, Houston. 

CAPCOM Challenger, Houston is with you through Yarragadee 

for 8 min. And Challenger, if you would prefer to call us the 
MMU temp data down instead of loading the PCCMU, you can. 

SPACECRAFT It's already loaded, John. 

CAPCOM That's fine. We'll take it on the PCCMU. 

CAPCOM Challenger, Houston. We're going LOS here at 

Orroral in a minute. We'll see you TDRS at 19 plus 31. 

SPACECRAFT Okay, John, and we've been having breakfast here. 
We just had an interesting pass against Australia, a fabulous 
view of the terrain here. 

CAPCOM Roger that. Looking forward to maybe seeing some 

of the pictures you'll are taking passing Australia at this time 
of the day.

the note on the change of the value of C2 that would go in tho 
deorbit prep book on page 7-12, 

SPACECRAFT We're getting a lot of static. 

SPACECRAFT Houston, Challenger. 

CAPCOM Roger. Go ahead, Vance. 

SPACECRAFT Yeah, John, we're getting a lot of noise, and we 
missed your note last time - - something about page 7-12 in 
deorbit prep. 

CAPCOM That's affirmative. We just wanted to make sure 

that you got the change that changes the value of C2 from a minus 
.62 to a minus . 60. 

SPACECRAFT Okay. That's affirmative, John. 
CAPCOM Understand, you did get the change. 

SPACECRAFT Roger. That's affirmative.

Houston, radio check. 

SPACECRAFT You're loud and clear, Houston. 

CAPCOM Roger, did you copy our transmission that the dump 

nozzle temp looks good to us now, you can go ahead and start the 
supply water dump? 

SPACECRAFT Yes, John, we copy that and Hoot's getting it. 
CAPCOM Okay. 

SPACECRAFT Houston, this is Challenger, water supnlv (garble) 
we got that nozzle too warm and the valve is binding. 

CAPCOM Hoot, you're going to have to repeat that, you're 

coming through garbled to us. 

SPACECRAFT John, what Hoot said is that the dump now appears 
to be not opened. The talkback is barberpole on (garble) R12. 
The talkback is closed and we're wondering if maybe the nozzle is 
too hot and was binding. 

CAPCOM Stand by 1, Ron, and I'll get you an answer. 

PA 9 This is Mission Control Houston, we're about a 

third of the way through this TDRS pass. The discussion about 
the water temp nozzles has to do with the valve nozzle through 
which water is jettisoned down the water dump. Activities on the 
fuel cells use hydrogen and oxygen passing across a membrane to 
produce electricity, and water is produced as a byproduct of that 
function. The production of water is to the extent that it 
exceeds the storage capability onboard the vehicle and, 
accordingly, it must be jettisoned. And when it's jettisoned 
it's sent out of the vehicle through a T-shaped nozzle, it's T- 
shaped to .... 

CAPCOM Challenger, Houston, we've looked at the data with 

EECOM and PAYLOADS and we understand why you couldn't get the 
valve open. Because the heater was off. You can delay the water 
dump, we'd like you to go ahead and delay it and start the water 
dump at 20 plus 15 so that PAYLOADS can get their last MOMS data 
take. 

SPACECRAFT Okay, John, we understand, start the water dump at 
20: 15. 



CAPCOM 



Roger, that. 



STS-41-B AIR/GROUND TRANSCRIPT t268j 039:08:38 2/8/84 PAGE 2 



PAO To continue, that water nozzle... 

SPACECRAFT (garble) 
CAPCOM Roger. 

SPACECRAFT The reason the heater is off is that we just turned 
it off and the situation is that we tried to dump and the nozzle 
temperature was 190. And then when we tried to dump, the nozzle 
valve would not open. We figured it might be just too hot since 
the temperature just needs to be over 100 to do that dump. We 
thought that the valve might be binding due to being too hot; 
therefore, we turned the heaters off, that's why you saw the data 
with the heaters off. 

CAPCOM Roger, understand that Bob and just clarify that 

you initially tried to open the valve with the heater on. 

SPACECRAFT That's affirmative and we'll try it again right 
now, if you'd like to watch. 

CAPCOM Okay, Bob, we'll wait til this MOMS data take is 

over and at 20 plus 15 when we start the water dump, we'll do 
that activity with you. 

SPACECRAFT Okay, John. 

PAO This is Mission Control Houston. To continue, that 

nozzle is T-shaped to facilitate the jettisoning of water in the 
opposite direction because if it was jettisoned only one way that 
would constitute thrust and would have an effect on the vehicle's 
attitude. So by jettisoning it out the opposite ends of a T- 
shape nozzle, the thrust effect cancels each other out. But that 
nozzle's also heated to protect against freezing in the extreme 
cold of space where temperatures routinely reach 100 degrees.... 

END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t269j 039:08:48 2/8/84 PAGE 1 

PA0 ~ ~ the thrust effect cancels each other out, but 

that nozzle's also heated to protect against freezing in the 
extreme cold of space where temperatures routinely reach 100 deg 
below 0 deg P. when, of course, that nozzle freezes, why it 
prevents water from passing through it, so that nozzle has to be 
heated, and the discussion now is about the possibility there's 
some blockage on that nozzle since they apparently tried to dump 
water through it with the heaters on and failed. Assumed then, 
that the temperatures were extremely high to the extent that it 
caused binding in that nozzle, then turned the heaters off to see 
if the cooling temperatures would facilite the water flow, but 
since that water dump's going to get in the way of a data take 
now m the payload's world, why, we'll postpone that water dumo 
until later on, and that subject will be readdressed. Riqht now. 
Mission Elapsed Time is 4 days, 19 hr, 50 min, and we have 
another half an hour or more remaining on this TDRS pass. This 
is Mission Control, Houston. 

CAPCOM Challenger, Houston. I have a heat pipe and mass 

spec flight note, when you're ready to copy. 

SPACECRAFT Okay, John, we're ready to copy. 

CAPCOM Okay, reference the heat pipe. Earlier today, we 

told you in a teleprinter message to delete the heat pipe 
deact. We don't want you to listen to our teleprinter message. 

Instead, we want you to go ahead and take perform the heat 

pipe deact at the nominal time, which is 4 days, 20 hr, plus 00 
min, and this occurred because, as we look back over our 
telemetry playback of the attempt to reset the heat pipe from the 
ground, that our experiment did not restart. So we'd appreciate 
it if you'd do that for us. 

SPACECRAFT Okay. We copy that, John. We'll deactivate the 
heat pipe at 4 days, 20 hr. 

CAPCOM Roger that, and also, on page 3-11 of the payload 

OPS checklist. When you're running the glow 1 program, number 7, 
at^tne end there, when you're on that page, let me know, on page 

SPACECRAFT Okay. Stand by just a second. Okay, John, I'm on 
3-11 looking at mass spec program 7. 

CAPCOM Roger, and over at the end of the procedure on page 

3-12, there where it says "when Orbiter has pitched to 360 deg, 
go to step 3", delete that there. Delete that step, but go ahead 
after then you've done the glow 2 program over on page 3-13 
though, retain that step, go to step 3. 



STS-41-B AIR/GROUND TRANSCRIPT t269j 039:08:48 2/8/84 PAGE 2 

SPACECRAFT Okay. We copy that, John, Up on page 3-12, delete 
the note about when the Orbiter is pitch 360, go to step 3. 
We'll go on into glow 2, and we will perform that step when we 
get to the end of glow 2 on page 3-13. 

CAPCOM Roger. Good readback, Hooter. 

CAPCOM Challenger, Houston. I have a flight note, 

reference the mass spec activation time when somebody's ready. 

SPACECRAFT Stand by just one minute, John. 

CAPCOM Roger that. 

SPACECRAFT Okay, John (garble) . 

CAPCOM We're not reading you, Ron. You're coming through 

very scratchy. 

SPACECRAFT Okay, John, that was Hoot transmitting. How are 

you reading me? 



CAPCOM 



I'm reading you loud and clear, Ron. 



SPACECRAFT Okay, John, this is Hoot again. How are you 
reading me? 

CAPCOM Reading you loud and clear now, Hoot. 

SPACECRAFT We're ready. 

CAPCOM Roger. Hoot, what we'd like to do here is make 

sure we get some things started on time, and there are a few 
errors in your CAP. First of all, we want you to start the mass 
spec activation for the glow 1 sequence at 20 plus 10. 

SPACECRAFT Okay. We copy, start the mass spec activation for 
glow 1 at 20:10. 

CAPCOM Roger, and then the start the yaw sensor test at 21 

plus 0 - - 

END OF TAPE

CAPCOM ... mass spec activation for the glow I sequence at 

20 plus 10. 

SPACECRAFT Okay, we copy. Start the mass spec activation fot 
glow 1 at 20:10. 

CAPCOM Roger and then start the yaw sensor test at 21 plus 



SPACECRAFT Okay, yaw sensor at 21:00. 

CAPCOM Right and finally, maneuver to -ZSI at 21 plus 33 

per the CAP. And Hoot, the only reason we're giving you a couple 
of changes there is because it's critical to do this sequence on 
time. Any delay in executing these activities or. time could 
prevent us and jeopardize the solar cell calibration experiment. 

SPACECRAFT Okay John, we copy that, thanks. On the yaw 
sensor, we did the positive yaw a couple of days ago, do we just 
do the negative yaw today? 

CAPCOM If you'll stand by, I'll get an answer from 

payloads for you. Challenger, Houston, Hoot, what we did the 
otrier day was an added test. We'd like you go ahead and do the 
full test today. 

SPACECRAFT Okay, we copy that John, we'll do the whole test on 
the yaw sensor. 

CAPCOM Roger, thanks a lot, Hoot. 

SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead. 

SPACECRAFT Roger, on that heat pipe deactivation, the SPEC 220 
came up with a, in item 22, the heat pipe already off. Went in 
and did inadvertent item 23 and cannot cycle back to 22. 

CAPCOM Roger, understand Ron. Payloads has been seeing 

that also and we'll look at it for you and get back to you. 

SPACECRAFT Okay 

SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead Hoot. 

SPACECRAFT Yes John, it looks like (qarble) direction, along 
side after the EVA, it wasn't quite all the way there, the way it 
looked out the window. Is that a fact, that you all got it 
squared away? 



STS-41-B AIR/GROUND TRANSCRIPT t270j 039:09:01 2/8/84 PAGE 2 
CAPCOM Roger, Hoot. That was as. 

SPACECRAFT (garble) you guys. 

CAPCOM Challenger, Houston. Ron, to get back to you on 

your heat pipe question. We would like to know currently whether 
your indication is showing your heat pipe power is on or off.

SPACECRAFT Yes, John, we're in the midst of glow one right now 
and it's come up time for the water dump at 20:15, We don't 
really want to do that with mass spec going on, do we? 

CAPCOM Hoot, payload says there's no problem with the 

water dump during mass spec. 

SPACECRAFT Okay, we'll do the water dump during mass spec. 

CAPCOM Challenger, Houston, we see the dump nozzle at 

temp. If you could go ahead and start the dump, we'd appreciate 
it. We'd just like to see it underway before we go LOS TDRS. 

SPACECRAFT Okay John, I'm ready getting ready to call you and 
tell you that I can't open the dump valve. 

CAPCOM Okay. 

SPACECRAFT Yes, I've been holding that switch over there, 
John, and the talkback in the cockpit stays closed. 

CAPCOM Okay, thank you. Challenger, Houston. If you'd go 

ahead and turn the dump valve nozzle heater switch to off and 
we'll think about it here and try to come up with a plan when we 
get to Yarragadee. 

SPACECRAFT Okay John, nozzle heater's off. 

CAPCOM Roger and see you at Yarragadee in 20 plus 33. 

We're going LOS in 2 minutes from TDRS. 

SPACECRAFT Thank you, John. Hey John, out of curiosity, at 20 
plus 00, did you (garble) power on or off? 

CAPCOM Challenger, you were coming through a little 

garbled, repeat your transmission. 

SPACECRAFT I was asking if that 20 plus 00, did you say heat 
pipe power on or off on your indications. 

CAPCOM Roger, we were showing that the heat pipe power was 

on.

CAPCOM And be advised Challenger, we're going to wait til 

this TDRS pass when we can see some data to work a little 
troubleshooting procedure on the dump valve problem. 

SPACECRAFT Okay John, we copy that. Hey John, I didn't copy 
your earlier transmission as to whether you saw the heat pipe 
power on or off. (garble) 

CAPCOM Roger Ron, we saw the heat pipe on with our data. 

And for your information, the heat pipe, in our estimation, is on 
and running. You can let it run until SPAS deactivation tomorrow 
and we saw this same type of phenomenon on STS-7, so no action on 
your part. 

SPACECRAFT Okay, okay thanks for the information. I believe I 
saw power off when it came up and we were beginning to wonder if 
the information I got on the CAP update was actually, that is 
deactivate that pushbutton (garble). ... on my part, thank you.

configuration around a little bit here, and we'll see (garble). 

SPACECRAFT Okay, John, looks like that comm configuration has 
taken care of my comm. Another note on the solar cell, the STS 
bus amp, the power bus amp did not change from the current 8 amps 
count on SPEC 219 when I did the solar power cycles. Over. 

CAPCOM Roger, we copy that, Ron, and pay loads has been 

saying down here that we don't think we're going to be able to 
get that experiment to run, so I don't think we have any further 
troubleshooting of the solar cell experiment. 

SPACECRAFT Okay, John. Okay, John, we're halfway to the solar 
attitude. Do you want us to stop that and go back to ZLV? 

CAPCOM Roger. We're happy that you just continued to 

maneuver by the clock, Hooter, because we have good Ku coveraqe 
with these attitudes. ^ 

SPACECRAFT Okay, copy that, John. We'll do that. 

SPACECRAFT Houston, this is Challenger. We think we're 
configured on the teleprinter with tha middeck audio center. 
Wonder if you could send us a test message, please.

CAPCOM Roger loud and clear, the comm sounds real good and 

we won't be able to send you that teleprinter test message until

SPACECRAFT Okay, thank you. 

SPACECRAFT I think we have it. Looks like we have a MOMS data 
take in progress. No, I see we have the experiment ops 
(garble). I was wondering about that. 

CAPCOM Roger. Challenger, Houston, we need to boil water 

for about an hour to get enough 0 engine tank bravo, so we'd 
appreciate it if you didn't start the EMU recharge for at least 
another hour. 

SPACECRAFT Okay, we copy that, Bruce says he'll hold off. 

CAPCOM Challenger, Houston, if somebody's at the back end 

of the flight deck, we need the TV power control to command and 
then INCO will be using camera alpha, if that's okay. 

SPACECRAFT Okay, that's in command. 

CAPCOM Thank you. 

SPACECRAFT Houston, Challenger.

CAPCOM Roger, go ahead Vance. 

SPACECRAFT As you know, this morning we have time to work in 
an IFM to dump supply water through the waste water dump nozzle 
if you all wish to do that. It doesn't look like it's a 
difficult thing to do and it might be easier doing now than 
sometime when we're really loaded up. 

CAPCOM Challenger, Houston. Vance, we understand that. 

That's a good idea but it would be a turnaround head to the Cape 
and we'd perfer not to do that and instead control it with the 
FES. 

SPACECRAFT Okay.

magazines, all of the data back type plus the following partial 
loads, 52 exposures in one magazine, 46 exposures in another 
magazine and 115 exposures remaining in a third magazine, third 
magazine so in effect we have about 5 magazines left. 

CAPCOM Roger, we copy and thanks for the report, Bruce. 

SPACECRAFT You bet. 

SPACECRAFT John, I understood to delay that EMU maintenance 
charge, does that mean you're going to delay the rev 80 TV as 
well, what's the status on that? 

CAPCOM Stand by one and we'll work that, that's a good 

question. Challenger, Houston, Ron I have an answer for your TV 
question. 2 

SPACECRAFT Okay, John, (garble) 

CAPCOM Roger, you are go for the TV over MILA of the EMU 

recharge and Bruce can go ahead and start his recharge at that 
point. If the timing doesn't work out that way, it is crew 
option as to whether or not you show TV at all on that pass. 

SPACECRAFT Okay, we copy that...

PAO ... conduit and thaw the ice blockage which is 

preventing that water dump from occurring. So, in the absence of 
the ability to dump water, the flash evaporator system's being 
used to remove water from tank bravo. The FES, of course, is the 
method by which a cooling of the vehicle's systems is achieved as 
a backup to the radiators in the payload bay doors. And at times 
when the payload bay's doors are closed or if there's some reason 
why heat radiation can't be effected through those instruments, 
the flash evaporator system is employed. Employment of that 
system at this time is exclusively as a mechanism to dump water 
from tank bravo. A weather briefing was conducted on the loop 
earlier today and there were no significant problems at any of 
the primary sites. Edwards, Kennedy, and Northrup are all 
acceptable landing sites if there's a need to deorbit and entry 
today. Northrup was declared unavailable earlier in the morning 
because of the expectation of high winds. Those winds never 
materialized, so Northrup is a valid recovery contingency site 
today, for contingency landings. We'll have acquisition of 
signal in 4 minutes through Yarragadee at mission elapsed time, 4 
days, 22 hours, 5 minutes, this is Mission Control, Houston. 

CAPCOM Challenger, Houston's with you at Yarragadee for 7 

and 1/2 minutes. 

SPACECRAFT Okay Houston, you're loud and clear at Yarragadee. 

CAPCOM Roger, you're loud and clear, also. And as we went 

over the hill, INCO was unable to command camera alpha off. If 
you could do that for us, we would appreciate it. 

SPACECRAFT Okay John, we'll get that. It's off, John. 

CAPCOM Challenger, Houston, and I have an item for you 

from EECOM when you're ready. 

SPACECRAFT Okay, we're ready, go ahead. 

CAPCOM Roger, at your convenience over the next 30 minutes 

or so, if you could do the 10.2 cabin maintenance procedure for 
us and flow nitrogen only. 

SPACECRAFT Okay, we copy, within the next half hour, 10.2 
cabin maintenance procedure and we'll flow nitrogen only. 

CAPCOM Roger, good readback, Hooter. Challenger, Houston, 

we're going LOS here in 30 seconds. We'll see you at Hawaii at 
22 plus 35. Enjoy your sunset over that beautiful Australian 
continent . 

SPACECRAFT We agree with you John, it is one beautiful 
continent and we also think we had kind of a far away look at 
tropical cyclone "Willie" a couple of minutes ago.

PAO Mission Control, Houston, We've lost video, and 

we'll pick up through the Merritt Island Station in about 1 
minute from now through MI LA, 

CAPCOM Challenger, Houston. We've lost the TV downlink 

for a few minutes until we come over MILA. Hoot, I have another 
flight note for you to try and troubleshoot the dump valve. 

SPACECRAFT Okay, John. Ready to copy. 

CAPCOM Okay, Hoot, what EECOM thinks now is that we may 

have some ice around the valve, so what he'd like to try is to 
take the supply water dump isol valve to close, check the 
talkback closed, then go ahead and take the dump valve enable 
nozzle heater to on, and just leave it on, wait until we get a 
high temp alert, and when you get the high temp alert, then try 
to open the valve. We're going to be increasing the high limit 
from 300 to 350 with a TMBU for you. 

SPACECRAFT Okay, John. We copy all that, and ... 

SPACECRAFT I've closed the isol valve, we'll turn on the dumo 

enable nozzle heaters (garble) high temperature alert which 
you're going to send up to us.

live TV on the middeck. 

SPACECRAFT Okay, good 

SPACECRAFT . Vance says that thing has a high (garble) at 
300, John, and I probably didn't break it by letting it go to 
200. Is that true? 

CAPCOM That's affirmative, Hooter, and we're going to even 

raise it up to 350, and just to try and melt ice around the valve 
if that's the problem. 

SPACECRAFT Okay, good. I'll go ahead and do that right now. 
CAPCOM Roger that. Thanks a lot. 

CAPCOM Challenger, Houston. We're really getting some 

very pretty pictures of you in the middeck, and just like you to 
know that Mr. Rousseau in building 5 saw you go over again this

looked pretty as you passed over our skyline. 

SPACECRAFT Well good. We're making a regular thing of it.

SPACECRAFT John, we noticed that the Cape weather has been 

looking good about every day whan we pass over it. 

CAPCOM Roger that, Vance. 

PA0 This is Mission Control, Houston. Bob Stewart just 

got the lubricating kit out which lubricates all the seals and 
interface points on the EMU to make sure they move freely and 
provide integrity and a good seal. 

SPACECRAFT And John, just out of curiosity, are you selecting 
your downlink scenes, or are you taking what I send you. 

CAPCOM We are taking what you send us, and if you have 

something else to send us, we'd like to look at it too. 

SPACECRAFT Can't get it all up at once. We'll save some for 
Hoot .

sure it's in TR on the teleprinter panel and make sure the air t 
ground 2 is either off or in receive on the other panels. 

SPACECRAFT Roger, John, that's affirmative. 

CAPCOM Thank you, Bruce. 

SPACECRAFT (garble) And John, I'd like to know, are there arm 
grapple procedures onboard? 

CAPCOM Stand by, Ron, I'll get you an answer. And 

Challenger, Houston, we currently have Ascension configured to 
send you a teleprinter test message at 23 plus 13. 

SPACECRAFT Okay, John, we copy, teleprinter 23:13. John, 
(garble) air sample. 

SPACECRAFT Houston, Challenger, how do you hear? 
CAPCOM Roger, loud and clear. 

SPACECRAFT Okay, as of — another call, that air sample, 
simply open a bottle, hear a hiss and the procedures — I just 
want to be certain as to how many of those we should take and 
just to be clear that that is in fact the proper procedure. 

SPACECRAFT John, I think we know that it's just one bottle at 
this time and simply consists of taking the cap off of the 
bottle, opening it, closing it and put the cap back on. Ron was 
wondering if there's a written procedure on that or if it's.. 

CAPCOM Negative Vance, there is no writttsn procedure, you 

have the correct procedure. 

SPACECRAFT Thank you. 

CAPCOM Challenger, Houston, Vance, just to follow up on 

your question, all you need to do now is take that air sample 
with that bottle now and then you can come back and take the 
final air sample bottle right before you do the repress. 

SPACECRAFT Okay understand, the final air sample is the oart 
we repress back to 14.7 psi.

PA 9 the tilt table on the mass spectrometer has 

failed and we're unable to cycle power to the solar cell 
experiment. Payloads officer indicates some curiosities of a 
notion that those failures might be related to overheating and 
we're looking now at a workaround which involves deactivating or 
powering down that whole SPAS experiment package and putting the 
ship in a cold attitude with the payload bay toward the deep 
space for an hour or two, perhaps an hour and half, to give the 
SPAS the opportunity to cool down and then see if that has any 
impact on the adequacy of those experiments. We still have 15 
minutes remaining in this TDRS pass, at 4 days, 23 hours, 20 
minutes. This is Mission Control, Houston.

is able to see your dump valve and we see the temperature is now 
up to 310 and he'd like you to go ahead and cycle the dump valve 
to — or move it to open and see if we can get it to open up.

water recharge, that's not going to affect the quantity qaqinq, 
is it?

and out with TDRS but we have good UHF for certain now with 
Botswana. Let me just start again. We saw the nozzle

(garble). Okay, John, disregard that last question. We got the 
answer onboard here. 

CAPCOM Copy that, Hoot. Challenger, Houston, we're going 

over the hill in 30 seconds. Hooter, what we'd like you to do is 
when you finally get the high temp alarm as you go over the hill, 
we would like you to try it one more time to see if you can get 
the dump valve to open. if it doesn't, we want you to turn the 
heater off, take the dump valve to closed and take the isol valve 
to open. 

SPACECRAFT Okay, I copy that and I'll do that, John. 
CAPCOM We'll see you at Yarragadee at 23 plus 45. 

SPACECRAFT Ok, see you at Yarragadee. 

PA ? Th is is Mission Control at Houston, we expect to 

talk to the crew through Yarragadee in about 7 minutes, there may 
be a configuration problem, however. The EMU, Extra-Vehicular 
Mobility Units that they've been working on are also equipped 
with UHF transmitters and the INCO sees from his data that one of 
those suits has the comm gear turned on* There is an antenna 
stowed presently in the airlock and that activated UHF circuit 
may have the effect of saturating the comm link and making it 
impossible for us to talk to the crew through Yarragadee. If 
that turns out to be the case, our next opportunity would be, to 
talk to them at Guam in 23 minutes. At Mission Elapsed Time 4 
days, 23 hours, 39 minutes, this is Mission Control Houston. 

CAPCOM Challenger, Houston, with you at Yarragadee. 

Challenger, Houston, going LOS Yarragadee, we'll see you at Guam 
in 6 minutes.

CAPCOM Roger, a note for Hoot when he's ready to copy. 

SPACECRAFT Ready to copy, John. 

CAPCOM Okay, Hoot, EECOM has another idea he'd like to try 

with troubleshooting that dump valve. He'd like you to let the 
temperature cycle for 3 cycles between 200 deg and 350 deg. If 
no joy after period, we'd like to go ahead and turn the heater 
off, take the dump valve, put it to close, take the isol valve 
and open it. 

SPACECRAFT Okay, John. I copied. We're going to let the 
temperature cycle 3 times between 200 and 350, and at the end of 
that if we haven't had any luck, we're going to leave the dump 
valve closed and the dump isol open, 

CAPCOM That's affirmative, and turn the heater off. 

SPACECRAFT Okay, yeah, and, of course, heater off. 

CAPCOM That's a good readback, and we're going LOS here at 

Hawaii in 45 sec. We'll see you up TDRS with the dump.

CAPCOM Challenger, loud and clear. 

SPACECRAFT Ok, just wanted to make sure we had you, here comes 
the dump and if we're ever running the recorder ahead, we'll give 
you some cabin scenes inbetween.

that's - - 

SPACECRAFT (Garble) 

SPACECRAFT Ok, thank you, thank you very much. We stopped to 
get your flight note. 

CAPCOM Ok, Vance, it's going to change your CAP this 

afternoon, and we have a teleprinter coming up to you that will 
give you activities starting at 1+35, but I have something I need 
you to go ahead and get started with now so I'm going to voice it 
up to you, 

SPACECRAFT We're holding the dump till you get it up. 

CAPCOM Ok, we need to, after glow-2, we need you to 

manuever to the -X local vertical, with the -Y velocity vector, 
target 2, body vector 2, omicron equal to 90, DAP A-auto vern, 
and initiate track. And then deactivate the SPAS, and I'll give 
you the rationale later. 

SPACECRAFT Ok, John, we can't hear you while we're dumping 
that, so we had to stop. Here it goes. 

SPACECRAFT Ok, loud and clear. 

SPACECRAFT Well, that may have been small step for Neal, but 
it's a heck of a big leap for me.

that is we're coming up. Looks like Florida, it is Florida. 
It's the Cape. 

SPACECRAFT Yeah, you're on the state side pass, Bruce. 

SPACECRAFT Ah I got to see if I can get a picture of this. 

SPACCRAFT You're not too far from Cuba as a matter of fact. 
And Houston, we had some helmet mounted TV on now. 



CAPCOM 



Roger, we got a little bit of it (garble) 



SPACECRAFT I think when you get out further, Bruce, we'll be 
able to see the whole ship, right now, we can see a corner of it. 

SPACECRAFT Okay. 

SPACECRAFT (Garble) out there, Bruce. 

SPACECRAFT Looks great, the sun just came into my eyes, and 
that's a little bright, but not a big deal. Flying over the 
Florida Keys sort of. 1900 on the left, 1800 on the right. 
Let's see how this state of the art ranging device is going to 
work. Well I show myself about 80 feet out, something like 
that. Could go faster, but why rush it. You got me on the TV 
ranger yet? 

SPACECRAFT Not yet. You're going right above the ship. 

SPACECRAFT All right, yeah, that's what I'm trying to do. 
Trying to find if it's working out. 

SPACECRAFT Say, you may get the name of the world's fastest 
human being, going along at 4 miles per second, Bruce. 

SPACECRAFT This record will only stand I guess for the next 
hour or so. 

SPACECRAFT We passed over Florida and Cuba.

to go ten percent faster.

around .3 yet. 

SPACECRAFT Okay, well, why don't I try to come to a stop here 

SPACECRAFT Yes, as a matter of fact you just had 150 feet so 

you probably better stop. 

SPACECRAFT Yes, I should be just about stopped now and I'm 

reading 125, so yes. You should have a range rate of iust about 
0 now. 

SPACECRAFT We're seeing about .2.

recorded on the video tape recorded now being relayed to the 
ground. 

SPACECRAFT Vance, you want me to go back over and get that 
blanket right now? 

SPACECRAFT Bob, what's your status right now. The next thing 
we have scheduled for you is to lock safety tethers and translate 
the MFR. Why don't you go ahead and do that to stay on schedule 
and get the blanket later. 



SPACECRAFT Got you.

LV, -YZZ, go ahead and deactivate SPAS? 



STS-41-B AIR/GROUND TRANSCRIPT t287j 039:13:39 2/8/84 PACK 2 

CAPCOM Roger, you can deactivate it now if you are done 

with glow 2, you can deactivate the SPAS while you're qoinq to 
that attitude. ^ ^ 

SPACECRAFT Okay, we'll do it. 

CAPCOM Okay, the reason we're doing this, we didn't have 

the opportunity to tell you there with all the confusion. But 
the SPAS is a little warm, and we needed to cool it down, so we 
wanted to go to a cool attitude, and we'll be sending you up a 
teleprinter message that will provide some changes to this 
afternoon's activities. For example, the first one at 1+35, will 
be to delete the yaw sensor. At 1+35 in the CAP. 

SPACECRAFT Houston, Challenger, I got most of that, we 

figured it was probably a heating problem on the SPAS. 

SPACECRAFT Okay, Vance, we propose that he presses on with 
his normal timeline of doing the MEV's task, and we also suggest 
if time permits to add a force evaluation getting the device at 
the MEV station and that's on FS11 and 12 box 19.

able to command pan and tilt from both the middeck or the fliqht 
deck and if you can't that function is just broken. 

SPACECRAFT Okay, thank you very much. We sort of suspected 
that might be the case but we weren't sure.

SPACECRAFT Did you get all rested up after yesterday. 
CAPCOM That's a negative. 

SPACECRAFT We're keeping you pretty, we kept you pretty busy, 
I guess . 

CAPCOM yes, I thought my workload was going to come down 

by 50 percent when you guys left town. 

SPACECRAFT Just went up, huh? 

SPACECRAFT Hey, Jerry. 

CAPCOM Go ahead. 

SPACECRAFT The HRM folks want to know their activation time 

it was day 5, 003530. ' 

CAPCOM Copy that Bob, thank you, and while we're taking 

attitude checks this morning, how do you guys feel after vour 
endeavors yesterday? 

SPACECRAFT Great. 

CAPCOM Ready to have at it again tomorrow, right? 

SPACECRAFT Ready and willing. 

SPACECRAFT The crew's in great shape here, Jerry. I think 
everybody^ just feeling on top of the world for the most part, I 
mean physically. A couple of disappointments on the mission but 
as far as adapting to 0g and everything, why it's really great.

I mean physically. A couple of disappointments on the mission, 
but as far as adapting to Og and everything, why it's really 
great. 

CAPCOM Copy, all that Vance. We certainly had a good time 

watching you all yesterday and you know you're the talk of the

thanks for the status. And Challenger, Houston. We've found cut 
that the weather you were looking at down there around Madagascar 
was rot a tropical storm. It was, however, a long extended 
troug... it extended all the way from the southeast coast of 
Africa, past Madagascar and out into the Indian Ocean for quite a 

SPACECRAFT Okay, great. Thanks Jerry. That's what we were 
seeing and we saw some rotations in the thing that lead us to 
believe that maybe it might be either building into a storm or a 
depression or something like that. Thanks. 

SPACECRAFT We talked it over onboard and we decided that in 
order to share all the good deals Vance and I get to go outside 
tomorrow. ^ 

CAPCOM That sounds fair to me Hoot, and for your 

information you guys, we've got some company up there this 
morning. The Soviets launched at 6:08 a.m., they're going up to 
rendezvous with the salute. And for your information, that makes 
an all time record having 8 f-lks in space at one time. 

SPACECRAFT Well, how about that. 

SPACECRAFT Oh great. It's really getting to be populated up 

SPACECRAFT Actually only two life forms. Make su-e we keep

SPACECRAFT And Jerry, Ron says he's going to fight all of us 
to go out outside tomorrow and I think he's tougher than any of 
us, so we may have to listen to him.

SPACECRAFT Fortunately, my suit's too small for any of them so 
I'm not worried.

SPACECRAFT Yes, I was told you have to get use to boots that 
don;t fit right. If I told a lie that big lightening would 
strike up and wipe us out. There she is, Hoot, talks to her at

CAPCOM Challenger, Houston at Guam for 7 minuses. 

SPACECRAFT Roger Jerry, loud and clear. 

CAPCOM Okay Vance, I've got several notes for you. First 

of all, we're sending message 45 charlie mass spec program 6 
procedures updates. Also, I'd like to talk a little bit about 
COAS and your H20 supply water dump procedures. 

SPACECRAFT Okay, go ahead. 

CAPCOM Okay Vance. We'd like to have a little of a bit of 

a status on what you found when you looked at the COAS mounting 
plate. Was it secure? Did you find any problems there? 

SPACECRAFT I didn't find any problems with it. Are you 
finding a scatter or a bias? 

CAPCOM We're finding both. We're finding about a half 

degree of bias and quite a bit of scatter in the marks you've 
been taking both yesterday and after you did the inspection 
today. Also, did you verify Vance that the barrel was indexed 
firmly to the ~Z position? 

SPACECRAFT Yes, sure did. It's been in that position the 
whole mission and it was checked each time. 

CAPCOM Okay, copy that. Just for your information, the 

set that you did before we depressed the cabin looks solid. It 
was probably in the tightest cluster we've ever had on a bunch of 
COAS marks. But the two that you've done since - -

CAPCOM - - about a half degree of bias and quite a bit of 

scattering the marks that you have been taking both yesterday and 
after you did the inspection today. Also did you verify, Vance, 
that the barrel was indexed firmly to the -z position. 

SPACECRAFT Yes, sure did. It's been in that position the 
whole mission, and it was checked each time. 

CAPCOM Okay, copy that, just for your information, the set 

that you did before we depress the cabin looks solid, it was 
probably in the tightest cluster we've ever had on a bunch of 
COAS marks. But the two that you've done since we depressed have 
been fairly large biases and a lot of scatter in them. 

SPACECRAFT And would you expect any bias, I know you wouldn't 
expect scatter, but would you expect any bias? 

CAPCOM We probably expected some, Vance, but not to the 

magnitude that we got. 

SPACECRAFT Okay, well, I don't know what to say. It seemed 
like the marks the last couple of times were not all that 
different from the first time. 

CAPCOM Okay, copy that. I guess just one final note on 

the COAS right now, we plan right now on doing an additional COAS 
cal, once we have repressed to 147. 

SPACECRAFT Okay, fine. 

CAPCOM Okay, next is the H20 supply dump. Vance, we would 

like you to go over to R12, ensure that the dump valve enable 
nozzle heater is on. We'd then like to take the supply H20 dump 
valve to closed, hold it for 5 seconds, looking for the talkback, 
close. After holding it 5 seconds, we'd like to go to open, hold 
it 5 seconds, and hopefully we'll see the talkback go open. 

SPACECRAFT Okay, want to go over to check, verify, that the 
supply dump heater is on, and tnen after that, take the H20 dump 
valve, go - well, cycle it 5 minutes open, then 5 minutes closed. 

CAPCOM Roger, Vance, all good, we'd like 5 seconds. 

SPACECRAFT 5 seconds open, 5 seconds closed. 

CAPCOM Roger that, and we're looking to see if we get a 

talkback open this time. 



SPACECRAFT Okay, in work. 



STS-41-B AIR/GROUND TRANSCRIPT t294j 039:16:09 2/8/84 PAGE 2 

CAPCOM And Challenger, Houston, Vance, I want to make 

sure we got things straight. On the dump valve we would like to 
go to close for 5 seconds, and then to open for 5 seconds. 

SPACECRAFT Okay, well I'm looking at the panel now, and the 
dump valve, enable slash nozzle heater was off, and the dump 
valve is closed, and I just turned the heater on, you want me to 
hold off or do this procedure immediately, and that would be to 
hit it closed for 5 seconds and open for 5 seconds, observing the 
talkback. ^ 

CAPCOM Roger, Vance, the temps and aline are okay, we'd 

like you to go ahead and enable the dump valve, the nozzle, the 
dump valve enable nozzle heater on, and then go ahead hold closed 
for 5 seconds and then open for 5. 

SPACECRAFT Okay, in work. Okay, that was performed, closed 
and then opened for 5 seconds each. No change in the talkback, 
it remains closed. 

CAPCOM Roger, copy that, Vance, you're go then to turn the 

dump valve enable nozzle heater switch to off. 

SPACECRAFT Okay, switch to coming off. 

CAPCOM And Vance, I've got one change for you on message 

39, if you can find it. That's a TMBU summary number 2. 

SPACECRAFT Okay, if it's the TMBU summary, it's downstairs, 
why don't I just copy what the change is and then go down and 
look for it. 

CAPCOM That's fine Vance, on line 14, you should move 

those 2 parameters one column each to the left. That will make 
the SM alert numbers low 42.0, high 90.0. And the 42.0 is the 
one underlined, that's the one that's been changed. 

SPACECRAFT Okay, and that was message 39. 

CAPCOM That's affirm, we're less then 30 seconds to LOS, 

Hawaii next in 6 minutes. 

SPACECRAFT Okay.

CAPCOM Go ahead, Vance. 

SPACECRAFT Your test on the supply water over-board dump with 
Hoot. What are your conclusions now, can you say, do think the 
line is frozen up definitely? 

CAPCOM That essentially is our conclusion on that, Vance, 

yes, we think the valve is frozen closed. 

SPACECRAFT Spacecraft attitude change some time or another 
help to unfreeze it? 

CAPCOM We're looking at it, we're rather doubtful it'd 

help, but we're thinking about it. 

SPACECRAFT Ok. 

CAPCOM Challenger, Houston, we see that you've set up your 

track option for your next manuever. We'd likt you to go to 
track on that one.

troubleshooting just a couple of minor anomalies. The crew had 
earlier turned off the SPAS, allowed it to cool off, and then 
they re going to be operating it a little later this afternoon. 
They will be doing the yaw sensor and solar cell experiments as 
well as the mass spectrometer activation. We're about an hour, 
at the present time, away from the beginning of the presleep 
activity which is usually the end of the day wrap up things 
including meal preparation and IMU alignments, that sort of 
thing, toward the end of the day. And we're getting to that 
point of the day where we will have very little crew 
communication very shortly. They are working some of the SPAS 
experiments and there was some troubleshooting of the valve 
problem on one of the water tanks. Earlier this morning we had 
the weather report from a Flight Dynamics Officer that weather at 
both potential landing sites for the weekend looks good. This is

right down over the island chain on that pass. Crew is going 
through some of the experiment operations with the SPAS, it was 
powered off earlier to allow it to cool down. Some of the 
experiment difficulties that they'd had earlier with were 
attributed to a thermal condition. They powered it down to cool 
off for a period of time and then reinitiated some experiment 
operations. Some of those experiment operations to be occurring 
a little bit later this afternoon. The crew is about 30 minutes 
away from the closeout of the routine activities today on the 
timeline. They get into their presleep activity in about half an 
hour and they're due to go to bed for the night about 3 pm this 
afternoon. The presleep activity is a 3 hour period that 
involves a number of things, but it's primarily not timely or not 
tightly timelmed period in which the crew can preoare and eat 
their evening meal, do some of the housekeeping functions onboard 
the spacecraft, catch up with any left over items from earlier in 
the day that they would like to keep up with. And they will be 
getting up to start their next day, flight day 7, about 11 pm 
central time and they'll be getting into the preparations for the 
second spacewalk of this flight, additional checkouts of the

satellite. This is the point in the day where the Flight 
Controllers here in Mission Control are beginning to review the 
condition of the systems onboard, decide what water dumps need'to 
be done, what quantities to hold in what tanks, that sort of 
thing, to have the ship all settled down for the night so the 
crew can get a good night sleep without any alarms of any kind 
disturbing them. We are in the scheduled crew presleep period 
now during which they would prepare their evening meal and do a 
few other minor tnings before the start of the scheduled sleep 
period about 3 this afternoon. About 30 seconds away from 
reacquiring through the TDRS. 

CAPCOM Challenger, Houston with you through TDRS. 

SPACECRAFT Ok, Houston, loud and clear. 

CAPCOM Got you loud and clear, too, Hooter. 

?^ 0M ^ . And cha Henger, Houston. Have a request for a 

software dump when you're ready to copy. 

SPACECRAFT Ok, go ahead. 

rt^° M a .u , Roger - We would to see a software dump of 

GPC1 and that's to try to help us troubleshoot the CRT 2 power 
cycles that you performed. And you can do that by using the malf 
book page 5-70. It's the DIPS SSR2 GPC software initiated memory 
dump, over. 1

SPACECRAFT Ok, Mary. We also will pump the cabin during 
presleep - - believe tnat we should pump it up with 02. 

CAPCOM And Challenger, Houston. We concur with pumpinq 

the cabin up with 02. 

SPACECRAFT Ok, thanks Mary. 

CAPCOM And Challenger, Houston. ECCOM's request inq that 

you go to 10-5 like you did last night. 

SPACECRAFT Ok, will do, Mary. We'll take it to 10.5. 

PAO Mission Control Houston 5 days, 5 hours, 30 minutes 

Mission Elapsed Time. The crew is bringing up the pressure in 
the cabin atmosphere up to 10.5 psi from the 10.15 that it's 
hovering around right now. They're bringing that up with 
additional oxygen and that will set them for the night and the 
pressure will gradually creep down to about the 10.2 level for 
tomorrows' EVA activities. 

CAPCOM Challenger, Houston back with you through TDRS. 

SPACECRAFT Ok Mary, and I'll do the software dump now. Hoot's 
getting the pressure adjustment. 

CAPCOM Ok, we're standing by. And also Vance, we did send 

up in AGO teleprinter messages 48 and 49. The 48 is presleep 
activity - - f f

CAPCOM Okay, we're standing by. And also Vance, we did 

send up in AGO teleprinter messages 48 and 49. The 48 is 
presleep activities for you, a couple of them. And then a block 
weather update on 49. 

SPACECRAFT Okay. 

PA0 This is Mission Control. During some of the 

recent conversations Capcom Mary Cleave asked the crew to prepare 
for a software dump off of GPC 1 to help them, help the ground 
controllers troubleshoot a peculiar item they have observed on 
CRT 2 associated with the power cycles on that display. Appears 
to be functioning normal. Apparently they've seen a couple of 
hiccups in the way that thing has worked and they have asked the 
crew to ship them the software out of general purpose computer 
number 1 to see if there is any clue to some of the odd things 
they have seen off that CRT. Crew is bringing the cabin 
atmosphere up now. It's, bring it around 10.3. They've got to 
bring it up to 10.5 before the evening. Challenger is on orbit 
number 84 just crossing the east coast of South America down at, 
near the lower reaches of its groundtrack about 28 and 1/2 
degrees south latitude and is moving out over the south 
Atlantic. This is the point of the day prior to crew sleep, when 
the flight controllers are reviewing the Orbiter systems. Trying 
to make sure that everything will be properly configured for the 
night, that the quantities of water in the water storage tanks 
are at a reasonable level, that the fuel cells have been purged, 
that the cabin atmosphere is in good shape, and all of the other 
associated maintenance functions are taken care of so that the 
crew will not be awakened during the night by any alarms calling 
for them to make any of those adjustments during the night. The 
crew in about an hour will be powering off the shuttle pallet 
satellite, it has been running some additional experiments, later 
this afternoon. And they will be turning that off in about an 
hour. It's about 2 hours and 25 minutes remaining before we put 
the crew to bed for the night. Usually the last communication 
with the crew is sometime before that as they try and let the 
crew follow their own pace during this presleep activity 
period. That period is a block of time about 3 hours in the crew 
activity plan during which the crew can prepare their evening 
meal and eat it and finish up any last minute items. It's not 
intended to be a time where they conduct experiments, although it 
usually is, does involve some end of the day wrap up of 
experiments. 

CAPCOM Challenger, Houston. Go ahead Vance. 

SPACECRAFT Okay. Software dump's complete. It's on OPS 

recorder 1, track 2, reverse. Percent of tape about 55 to 60 and 
MET is 5 days, 5 hours, 34 minutes, 5 seconds. 



CAPCOM 



Okay, we copy that. Thanks.

CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead. 

CAPCOM Roger, Vance. No crew action required, just 

wanted to let you know that the MOMS data take is complete and 
that's all wrapped up for the rest of the flight. 

SPACECRAFT Okay, real good. Understand, sure hope it all 

turns out. 

CAPCOM Roger, we copy. And Challenger, Houston. We'd 

like to do a waste tank dump with one delta this evening, and if 
you'd go to ML 31 charlie, to start with, just one step, and take 
the waste water dump valve enable nozzle heater to on. 

END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t300j 039:18:39 2/8/84 PAGE 1 



CAPCOM - - and if you would go to ML 31 Charlie, to start 

with, Dust 1 step, and take the waste water dump valve enable 
nozzle heater to on. 

SPACECRAFT Ok, you want us to do that now, is that what I'm 
hearing? 

CAPCOM Roger, just to set up for the dump, we'd like one 

action on ML 31 Charlie waste water dump valve enable nozzle 
heater on, and then on our call, we'll ask you dump the waste 
tank to 0 percent. 

SPACECRAFT Ok, I'm going down there to get that heater now, 
Mary. ' 

CAPCOM Roger, Hooter, we've got one change to that dump 

procedure for this evening, so if you wanted to grab your orbit 
ops checklist on the way back up and I'll talk to you about that 
when you're ready. 

SPACECRAFT Ok Mary, I'm with you on pg 5 dash - - 

CAPCOM Ok, Hooter, pg 5-4, and if you go over on pg 5-5, 

under step 2 dump termination, that first callout on ML 31 
Charlie, we would like you to leave the waste water dump isol 
valve open. 

SPACECRAFT Ok, that's what we did on the other dump too, was 
leave the waste water dump isol valve open and I'll leave that 
open again. 

CAPCOM Roger, Hoot, and we just wanted the heaters on so 

ECOM could take a look at the data while we're still here under 
the TDRS umbrella. 

SPACECRAFT Ok, sounds good. 

CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead, Mary. 

CAPCOM Roger, Hoot, on that message 44-alpha that we sent 

up on the SPAS ops updates, there was a callout for, at 5 days, 5 
hours, and 50 minutes, about 5 minutes from now, you were suppose 
to perform Mass Spec activation, and we'd like you to know it's 
already on and so that could be deleted, however, payloads would 
like to know how close to the -z you were able to get the Mass 
Spec. 

SPACECRAFT Mary, it looks like right now that the Mass Spec is 
about 10 or 15 degrees from being -Z . 



STS-41-B AIR/GROUND TRANSCRIPT t300j 039:18:39 2/8/84 PAGE 2 

CAPCOM Ok, copy that, and also we'd like to get some 

verification that you did receive the 2 teleprinter messages that 
we sent to you at AGO. y 

SPACECRAFT Ok, let me check - - 

SPACECRAFT And Mary, we just received message 49A. 

CAPCOM We copy you just got message 49. 

SPACECRAFT And Mary, we do have 44 Alfa that's the one on the 
Mass Spec. 

CAPCOM Roger, we need a verification on 48 and 49, which 

we just sent over AGO. And you said you did get 49, did you qet 
the 48 also? ^ 

SPACECRAFT Ok, stand by while we make sure, Mary. 

CAPCOM Ok, sorry to keep running you around like this. 

Challenger, Houston, if it'll help you out, 48 was sent after 49, 
and 48 is a block weather update. 

SPACECRAFT Ok, 48' s the weather update. Ok, yes, we have it, 
that threw us off as it came after 49A, but it's right on the 
same sheet of paper. 

CAPCOM Ok, thanks, Vance, they switched the order around 

because 49 had a higher priority. Challenger, Houston. 

SPACECRAFT Go ahead, Mary. 

CAPCOM Roger, Vance, we wanted to verify that in your IMU 

align roll startracker that you are doing step #2 of pg 7-4 

initiate roll at sunset, where you are doing an LVLH auto-track. 

SPACECRAFT Yes that's affirmative, Mary, the note, well the 
note on step 6 in Mass Spec confused us momentarily, but that's 
the way we're doing it. 

CAPCOM Copy. Challenger, Houston. 

SPACECRAFT Go ahead, Mary. 

CAPCOM Roger, for Hoot, there will be no waste water dump 

tonight. The signature on that dump nozzle heater looks about 
the same as the one previously on your water dump nozzle, so we'd 
like to hold and just back out of this dump for this evening. 
Take your waste water dump valve enable nozzle heater on ML 31 
Charlie back to off.

we're about 30 seconds LOS and 
and did you copy the last on 
dump. 



SPACECRAFT That's affirmative, Mary, Vance is on his way down 
to shut it off. 

SPACECRAFT Yes, we're having trouble keeping the mass spec in 
the -Z direction. It goes there, holds for a few seconds, and 
then goes back to -X. It's holding at the moment, we started the 
roll maneuver. Still holding. 

CAPCOM Copy that. 

SPACECRAFT It went back to +X after the maneuver had started 
and I did a - (garble) . 

PAO This is Mission Control Houston, at 5 days, 6 

hours, 2 minutes, mission elasped time. We have loss of signal 
with the Challenger, through the tracking data relay satellite at 
the start of orbit number 85. And we'll pick up again in about 
22 minutes for a very brief pass, over the Guam station, just 
over the edge of the range of that station. May not be any 
communications through that one. And after that, 30 minutes from 
now, 31 minutes from now, we'll pick up over the Hawaii 
station.

CAPCOM Roger, copy, thanks, Bob. 

SPACECRAFT Mary, I wasn't sure if I made my question clear 
last time, I was questioning the fact that in the previous step 
we were instructed to delete Mass Spec shield close. The item 
6+1, but we were not instructed to do so in step 7, deactivation, 
where we are again asked to perform an item 6+1. The question is 
do we delete it in step 7, or perform that step as written, 

CAPCOM We're checking on that now for you, Ron, and we're 

about 20 seconds LOS, we'll talk to you through Hawaii at 6+33. 

SPACECRAFT Roger. 

PAO Mission Control Houston, we'll be getting some 

Earth views from the spacecraft at 1:44, spacecraft TV being 
downlinked and we're in acqusition through the Hawaii station. 

CAPCOM Challenger, Houston, with thru Hawaii for 7 

minutes . 

SPACECRAFT H. Mary, we've got you. 

CAPCOM Got you loud and clear, too. Got a couple items 

for you. 

SPACECRAFT Ok, ready to copy. 

CAPCOM First of all, answering Ron's question left from 

Guam, they want you to do that Mass Spec deactivation with 6+1, 
they do need the shield work done, and so it's to be performed as 
originaly written. 

SPACECRAFT Ok, we'll do that. 

CAPCOM Also, they didn't get Ron on UHF through Guam, and 

so we'd like him to check his UHF con fig. 

SPACECRAFT Ok, yes, he had that changed for some VTR recording 
that he was doing, so we'll get that fixed. 

CAPCOM Ok, fine and I have some changes to your CAP when 

you're ready copy. 

SPACECRAFT Ok, re.^dy. 

CAPCOM At 5 days, 6 hours, 40 minutes, after the SPAS 

deactivation that was scheduled in your teleprinter message of 
#4 4-alpha, we'd like tc add, load PCMMU format per the orbit ops 
.;nock:i i::t, lood formats 103 161. 



STS-41-B AIR/GROUND TRANSCRIPT t302j 039:19:25 2/8/84 PAGE 2 

SPACECRAFT Ok, that's go to PCM formats 103 and 161 after SPAS 
deactivation. 

CAPCOM Roger, and then also we would like you to FDA on 

your Decom 4 disabled. 

SPACECRAFT Ok, we'll do. 

CAPCOM Then have 3, 2 items that we're going to give you 

in presleep here because they're real early and you might not get 
to them before your mail call tomorrow morning. 

SPACECRAFT Ok, good idea, Mary. 

CAPCOM At 5 days, 16 hours, and 10 minutes, we'd like to 

add SPAS 01 activation per the Payload Ops checklist SPAS 01 
activation. At 5 days, 16 hours and 10 minutes, we'd like to add 
Mass Spec, Step 1 for the Payload Ops SPAS 01, and that's a SPAS 
01 attached experiment. 

SPACECRAFT Ok, boy you're really going to out us to work 
early, Mary, at 16:10 tomorrow morning, that's at 5 days 16:10, 
we will do SPAS activation and then ready the Mass Spec step 1. 

CAPCOM That's a good readback. And Challenger, Houston, 

when you're ready to read down the IMU alignment numbers, GNC'd 
like the info. 

SPACECRAFT How about that, I was just getting ready to push 
the button to ask you if you wanted to hear those Ok, when 
you're ready I'll read them. 

CAPCOM Ready to copy.

Mission Control Houston, 5 days, 6 hours, 41 
minutes, we have loss of signal through the Hawaii station, we'll 
pick up in 3 minutes, on the tracking data relay satellite, where 
we will be getting some television, through the satellite of 
earth views, downlink television from the Orbiter today. Crew 
Dust has a little over an hour, about an hour and 15 minutes, 
remaining in their day. They are already mote than half way into 
the presleep period, during which they do the last minute clpan 
up items for the day, prepare their evening meal, and consume 
that, and make sure all the systems are buttoned down, and 
Orbiter's systems are ready for the night. They'll get to work 
tirst thing in the morning, powering up the SPA's and some of its 
experiments before they begin their pre-EVA actvities. We're 
about 2 minutes away from picking up through tracking data relay 
satellite. This is Mission Control. Mission Control, we have 
acquisition through TDRS. 



CAPCOM 
now. 



Challenger, Houst^.i, back with you through TDRS 



SPACECRAFT That is not the component, but the pointing will 
have to be 85 degrees out of point. 

CAPCOM Challenger, Houston. Challenger, Houston, with you 

through Santigo. 1 



SPACECRAFT 



Oh. 



CAPCOM And Vance, if you're not using the bay cameras we'd 

like to use them. 

SPACECRAFT You can still have them, you want us to, we'll have 
to look to see, I think we're off, so you want us to go to 
command? * 

CAPCOM That's negative, Vance, you don't have to do 

anything, we'll just take them over. And also if you have that 
middeck speaker configuration along with the teleprinter, we have 
the test message here, and if we don't get it up here it will be 
a while before we hit a site again. 



STS-41-B AIR/GROUND TRANSCRIPT t303j 039:19:36 2/8/84 PAGE 



SPACECRAFT Yeah, we're just now getting around to presleep, 
I'm not sure we've got that all set up, just a second. And Mary 
did you get the comment about the prop or did we have a drop 
down. * 



CAPCOM Must have dropped out say again. 

SPACECRAFT We were just kidding around up here, Hoot was 
looking at his RCS, how goes it chart, his OMs chart, and there' 
so much excess propellant, we figured we will probabi ' have to 
point about 85 degrees out of plane on the deorbit burn. 

CAPCOM Copy that. 

PA0 This is Mission Control, we're getting live 

television downlink as the spacecraft just about to cross the 
coast of south America. 

SPACECRAFT Okay, Mary, on the downstairs speaker, we're ready 
for you to send us a teleprinter message. 

CAPCOM Okay, we copy that. And Challenger, Honston, 

they re sending you teleprinter message 50 alpha again, throuqh 
this new configuration. 

SPACECRAFT Okay, 50 alpha. 

CAPCOM Also on your RCA 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t304j 039:20:04 2/8/84 PAGE 1 
SPACECRAFT Okay, 50 alpha. 

CAPCOM Also on your RCS how goes it, suggestion, you're 

going to have a RCS optimum tig, with a 3 minute download. Tank 
fill coverage, above safe HP, and no waste in angle. And that's 
calculating it with DTO 403 on flight day 8. 

SPACECRAFT Okay, no wasting angles, good deal. 

CAPCOM Roger, and triple down mode, if we don't pick you 

back up on TDRS after this AGO pass, we'll get you through 
Ascension, at 7:17. And Challenger Houston, we didn't get that 
teleprinter message up to you in the new configuration. We'll 
try to send it to you at Ascension. 

SPACECRAFT (garble) 

CAPCOM Challenger, Houston, back with you through TDRS. 

SPACECRAFT Okay, Mary, loud and clear on TDRS. 

CAPCOM Got one, couple more presleep activities for you 

trom the ECONs. J 

SPACECRAFT Okay, go ahead with them. 

CAPCOM First of all on panel LI, we'd like you to take 

your rad controller out temp to normal, and then take flash 
evaporator primary A to off and then on. 

^ E ^ AF Lo ~ ay ' Mar *' we took the ra <* out temps to normal, 
took the FES off and then back to on. 

CAPCOM And then we'd like you to go ahead and verify, 

PP02, caution and warning for the evening. Channel 34, which is 
PP02 alpha at 3.2 volts dc. Channel 44, which is PP02 bravo, 
verify 3.1 volts dc. That's the hardware, we'll do the software. 

SPACECRAFT Okay, thanks, Mary, we'll check 34, 3.2; 44, at 
3.1, that's the upper limit. 

CAPCOM That sounds good. And Challenger, Houston, have a 

sentence on your CRT 2 problem, well, at least a problem they're 
trying to work out now. 1 

SPACECRAFT Okay, go ahead. 

CAPCOM First of all, this, there's nothing wrong with GPC 

1 and there is nothing here that could cause the fail to sync 
problem. What they think, if anything is wrong, they're going to 
track it down to a BCE on DK 2, it's logging the wrong errors! 



STS-41-:^ AIR/GROUND TRANSCRIPT t304j 039:20:04 2/8/84 PAGE 2 
SPACECRAFT Say the last sentence again please. 
CAPCOM BCE to DK 2, it's logging the wrong errors. 

SPACECRAFT Okay, understand. 

^° 0M *. fc w An f* Vance ' it,s logging MSC's instead of initial 
time outs they think. 

SPACECRAFT Anyway only indication problem, right? 

CAPCOM That's affirmative, no indication problems at 

all. 

p A0 And this is Mission Control 5 days, 7 hours, 10 

minutes, we've been getting live television downlink from the 
orbiter through the payload bay cameras. Orbiter is now over the

Amer ica . 

CAPCOM Challenger Houston, with you over Ascension for a 

couple of minutes. 

SPACECRAFT Clear at Ascension. 

CAPCOM Got you loud and clear. And looks to us, like you 

should have 50A onboard through Ascension using your mid speaker 
set up tor the evening. 

SPACECRAFT Okay, we'll give it a check, we didn't get anything 
through the speaker, so that part must be working. 

CAPCOM That sounds good. 

SPACECRAFT Ye-h, Mary, we're right in the middle of getting it 
now. ^

you through Guam at 7+57. 

SPACECRAFT Ok, Mary, we'll see you at Guam. 

PAO This is Mission Control at 5 days, 7 hours, 38 

minutes Mission Elapsed Time. Challenger has passed out of the 
range of the Tracking Data Relay Satellite on orbit #86 and is 
approaching the continent of India. We have about 20 minutes 
remaining before the crew is put to bed for the night, completing 
their activities for the day. Final checks of the Orbited 
systems being conducted by the Flight Controllers here in mission 
Control, and any necessary adjustments being read up to the 
crew. This is Mission Control Houston. 

PAO This is Mission Control at 5 days, 7 hours, 56 

minutes Mission Elapsed Time. We're about to acquire 
communication with the Challenger over the Guam station. We're 
right at the start of the scheduled crew sleep period, so we may 
not have any communication with the crew. For the last few hours 
here in Mission Control, the flight planners and flight 
controllers have been checking on the Orbiter's systems making 
sure that everything is buttoned down for the night. All the 
proper limits are set on the caution and warning system that the 
crews cabin atmosphere is properly adjusted, fuel cells have been 
purged, IMUs aligned Lithium Hydroxide cannisters changed out and 
that sort of thing so that the crew is not awaked by any 
necessity during the night to change any of those items. Crew's 
due to get up about 11 pm Central Time and start what promises to 
be a very busy day with a very busy day with the 2nd space walk 
of the Challenger's flight. 

CAPCOM Challenger with you through Guam for 5 minutes. 

Challenger, Houston with you for 4 minutes. 

SPACECRAFT Roger, Mary. Just listening to some music up here. 

CAPCOM And Challenger, just a reminder with your presleep 

work, that we have not seen a cable-unwrap yet thJs evening. 

SPACECRAFT No, and probably a few other things too. 

CAPCOM And Challenger, Houston, just one more item, and 

we'll leave you alone for the evening. We owe you a state 
vector, we're going to put that up as soon we get TDRS AOS here 
on rev 86, and that should hold you until rev 91. 

SPACECRAFT Ok, real good, and we received message 50A 

CAPCOM Ok, thanks, we copy, you received 50A And verify 

that there was no sound or problem with that. 



9TS-41-B AIR/GROUND TRANSCRIPT t305j 039:20:20 2/8/84 PAGE 2 



SPACECRAFT No problem. 

CAPCOM Sounds real good. And Challenger, Houston, we'll 

tuck you in for the evening with a correction, that state vector 
we give you at TDRS AOS will be good to rev 93, and hope you have 
a good night's sleep. 

SPACECRAFT Ok, rev 93. And we'll get that cable unwrapped 
here pretty quick and finish the rest of the items. 

CAPCOM Copy, good night. 

SPACECRAFT Ok, Mary, you should see that cable unwrapped now. 
CAPCOM Ok, we copy. 

PAO This is Mission Control Houston, at 5 days, 8 

hours, 3 minutes Mission Elapsed Time. Challenger passing out of 
the range of the Guam station on orbit #86. Crew informed that 
state vector would be shipped up automatically via the Tracking 
Data Relay Satellite when they come in contact with that 
satellite's range in about 18 minutes. That gives them the 
proper onboard guidance navigation for the evening, carry them 
through the sleep period. The Flight Director Harold Draughon 
did a status check here in Mission Control with all the Flight 
Controllers to be certain that they were happy with the way their 
systems were configured for the night and then CAPCOM Mary Cleave 
gave the official good bye for the night from this flight control 
crew at the end of flight day 6. Tomorrow flight day 7 begins 
for the crew about 11 pm Central Time when they get up and power 
the Shuttle Pallet Attached Satellite and begin getting ready for 
their EVA. This will be the 2nd EVA of the flight, the 1st one 
lasted 5 hours and 55 minutes. This one will be of similar 
duration beginning at about 5 am Central Time. The highlight of 
this EVA, in addition to some additional checkouts of the Manned 
Maneuvering Units, there will be a practice docking with the 
slowly rotating SPAS - -

PAO attached satellite and begin getting ready for 

their EVA. This will be the second EVA of the flight, the first 
one lasted 5 hours and 55 minutes. This one will be of similar 
duration, beginning at about 5 am central time. The highlight of 
this EVA in addition to some additional checkout of the man 
manevering units, there will be a practice docking with the 
slowly rotating SPAS. The SPAS will be taken out of the cargo 
bay by the remote manipulator system, the mechanical arm. And 
rotated at a rate of about 1 degree per second to match the 
rotational speed that the astronauts would expect to encounter 
when they go up to repair the solar maximum satellite on the next 
Shuttle flight. That satellite launced in February 1980, shortly 
after its launch to observe solar phenomena during the maximum 
period of the solar cycle, experienced some electronic problems, 
and it slowly began turning which it eliminated its capabilities 
as a working observation satellite. The crew will on flight 13, 
which is actually flight 41-C, will rendezvous with that orbiting 
satellite, which has been up for four years now, will match it's 
orbit, crewmembers will go out in the MMUs, one crewmember will 
match up with the rotational speed of that satellite, will dock 
with it, and use his MMU to slow it's rotation, the satellite 
will then be grappled by the remote manipulator arm and returned 
to the cargo bay of the Shuttle where it will be worked on, the 
main electronics box will be repaired and the satellite will be 
returned to a useful orbit. We don't expect to hear from the 
crew again tonight. They are now in their scheduled sleep period 
and as we left them a few minutes ago, they were listening to 
some music, and making the final, going through the final 
activities that they had before they got into the sleep period. 
Planning team of Plight Director, Larry Bourgeois, is coming on 
board now, and the handover will be getting under way shortly in 
Mission Control. That team will be reviewing the planned EVA 
activities, all the other activities for tomorrow, flight day 
7. Making the changes to those, and any changes will be updated 
via teleprinter messages to the crew tonight. We're at 5 days, 8 
hours, 7 minutes, mission elasped time. This is Mission Control 
Houston. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston, go ahead. 

SPACECRAFT Roger, surprise, surprise, we just had a fail off 
on 2 manifold (garble) jets R5R and R5D. 

CAPCOM Okay, we're looking at it now. Roger, we saw that 

Vance, we're looking at it now. 

SPACECRAFT That's your selected, and we're on primaries, and 
just for the moment I guess we'll to that aft jets option.

looking at, I'll get bac.': to you in a second. 

SPACECRAFT Okay. 

SPACECRAFT Houston, Challenger. 



CAPCOM 



Challenger, Houston, go ahead, Vance. 



SPACECRAFT Ah, Guy, we're on the aft jets, and standing by, 
we, we're looking at the hot fire procedure, in case you want us 
to do anything like that, so we're standing by. 

CAPCOM Okay, copy, Vance, what we'd like to do for sleep 

tonight, is just stay on tail only jets, if we hot: fire it, then 
we wouldn't be positive they wouldn't kick off again toniqht 
anyway, so we'd like to just stay where you are, we'll sleep on 
tail only, and we need to look at the data. It looks like there 
is a problem in the, one of the redundant power sources to RJD 5 
manifold, but the only anominally we'd like from that procedure, 
is for you to leave the vernier RJD driver on tonight, so we can 
look at it some more. 

SPACECRAFT Okay, well it's on right now, we didn't turn it 
off, and so I guess we're in the configuration for you to watch 



CAPCOM Roger, Vance, looks good, thank you.

SPACECRAFT And Houston, Challenger.

SPACECRAFT Looks like we've got a minor problem with the WCS 
in addition to the separator thing that happened earlier. We, 
it's tending to fill up. We're having a hard time getting - - 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston back with you Vance. We had a 

dropout. I copied the WCS minor problem, tending to fill up and 
then we were cut off. 

CAPCOM Challenger, Houston. How do you read that Vance? 

SPACECRAFT Okay, I think we have you now. 

CAPCOM Okay, Vance. We had tried :o get high data rate 

there to look at the RCS and it apparently didn't work. We're 
back on low data rate. All I copied on their WCS was he had a 
minor problem that was tending to fill up. 

SPACECRAFT Tending to fill up, but also the material is 
tending to come up to a level that's at the bottom of the 
transport tube. And it's hard to manually move out of the way, 
with a probe of some kind. Also, we just noticed a short time 
ago, that the circuit breaker on the slinger on panel ML86 is 
popped. 

CAPCOM Roger, copy that Vance. Let me see if somebody's 

got some words for you. 

SPACECRAFT Okay. Well there's another one for you to think 
about tonight I guess. 

CAPCOM Roger. 

PA0 Mission Control Houston. Propulsion Systems 

Officer here in Mission Control taking a look at an apparent 
problem in one of the aft verniers. Seems to be a problem that 



STS-41-B AIR/GROUND TRANSCRIPT t307j 039:21:44 2/8/84 PAGE 2 



drive or power on jet RJD5 will not stay redundant, and what they 
have done is taken a playback from the system, going over that 
data now. They also are sending up a configuration to the ship 
that will leave all primary jets in redundancy tonight, and they 
will stay tail-driven for the night, take a look at the data. On 
that last communication Commander Vance Brand also reporting a 
problem with the waste compartment system. One of the circuit 
breakers on the slinger popped and they are having a problem 
keeping the material where it's supposed to go. At mission 
elasped time 5 days, 8 hours, 51 minutes, this is Mission Control 
Houston. 

SPACECRAFT Houston, Challenger. 

CAPCOM Go ahead Vance. 

SPACECRAFT Well with the latter problem, we've had some 
success. We all flipped coins and Hoot lost, and he took a ply- 
bar and he said that stuff was sort of like freezedried or adobe 
consistency or something like that. Anyway, he pried it loose 
and now that area is clear in the WCS right below the transport 
tube where a slinger is and he wonders if we could reset that 
circuit breaker and see if it will spin up, which it should 
because it's clear. 

CAPCOM Roger Vance, and you have a go for resetting the 

circuit breaker and trying it again. 

SPACECRAFT Okay. 

PA0 Mission Control Houston. Commander Vance Brand 

reporting that Pilot Hoot Gibson managed to clear the transport 
tube in the WCS with a pry bar and mean time EECOM and flight 
have given an affirmative on the plan to reset the circuit 
breaker and the crew's doing that now. Mission Control Houston 
at 5 days, 8 hours, 55 minutes. 

SPACECRAFT Okay, Guy. I guess it's all right now. Sorry we 
had to bother you on that but it's just something we'll have to 
watch in the next couple of days, make sure the problem does not 
reoccur . 

CAPCOM No problem Vance. And Vance, if the problem 

reoccurs you've just got to go to reset the circuit breaker and 
try the same, after clearing it out and try the same procedure. 

SPACECRAFT Okay. Turns out that slinger is just sort of in 
the way since it, well it had a function when they had (garble) 
on there I think, but now it's really, maybe not just optimum —

SPACECRAFT Okay, it turns out that slinger's just sort of in 
the way since it, well it, had a function where they had times on 
there I think, but now, it's really maybe not just optimum. 

CAPCOM Roger, copy that, Vance, and that's okay, we had, 

we enjoyed the problem, we got to call Mary back in. 

SPACECRAFT Well at least I guess you got a little excitement 
on the late shift, huh. 

PA0 And that was Commander Brand reporting almost 

simultaneously with EECOM down here in Mission Control that the 
circuit breaker did stay in and CAPCOM Guy Gardner teasing that 
they had brought orbit 2 CAPCOM Mary Cleave back in to help them 
troubleshoot the toilet problem. 

CAPCOM And Challenger, Houston, just to... 

SPACECRAFT Go ahead. 

CAPCOM Roger, Vance, just to let you know here and put you 

to bed, we like the RCS config, looks good, and we'll just stay

PAO Mission Control, Houston. The mission summary is 

being checked out here at Mission Control and approved prior to 
uplink to the crew. Part of their morning news package has 
already gone up at Dakar. The Orbiter now is on rev 90 over the 
Persian Gulf area. Mission controllers continue to monitor the 
verneir jets just before crew sleep period beg?n, Earlier foday, 
there was an anomaly in one set of verns, referred to as R5R and 
R5D. Those are small, efficient jets on the back end of the 
Orbiter and the problem was an intermittent loss of driver 
power. And the propulsion officer here reports that in the event 
that those do continue to function in that manner, the work- 
arounds would be simply to reselect vernier jets or, failing even 
that, the next step would be to use primary jets. And he 
reported also that in the event they had to go to primary jets 
for the remainder of the mission, they're way, way above all the 
levels of propulsion fuel and that sort of thing that they would 
need to make that happen. So that if for instance, there were a 
contingency need to move the Orbiter around during the EVA or 
anything like that. All of those different contingencies have 
been taken into account and even with those, they're well above 
the level of fuel they would need to accomplish the rest of their 
mission using primary jets alone, so it's not seen as a serious 
problem. At mission elapsed time, 5 days, 14 hours, 2 minutes, 
this is Mission Control, Houston.

CAPCOM Roger, copy Vance and be advised, I think every 

time Ron talks, we're getting him down here on the air-to-ground. 

CAPCOM Challenger, Houston with a note on the water dump. 

SPACECRAFT Yes Guy, go ahead. 

CAPCOM Okay Hoot, we'd like you to go ahead and dump the 

supply water tank bravo to 30% and we'd like you to leave the rad 
controller outlet temp to norm, do not go to high with that. 

SPACECRAFT Okay Guy, sounds good. We'll dump tank B to 30%, 
leave the rad out temp normal. 

CAPCOM Rog, thanks. 

CAPCOM Challenger, Houston, you can go to auto on the DAP 

now. 

SPACECRAFT Roger, auto on the DAP. 
CAPCOM Thank you, Vance. 

PA0 Mission Control, Houston. The crew has been given 

a go ahead if they are ahead in their EVA prep timeline this 
morning to go ahead and depress the airlock as much as a half an 
hour early to give them a little bit more time to work on the 
camera D changeout. They're going to take a new camera from the 
cabin and stick it out of the payload bay where the other payload 
bay camera D had been. So it's possible we could get slightly 
earlier than anticipated EVA. That's basically crew option and 
we'll know more about that as we get closer to it. The crew has 
been asked to take a look for 3 tropical storms and an 
interesting volcanic eruption on the globe this morning during 
their passes around the earth. There are a couple of tropical 
storms. One's named "Annette", the other named "Willie" in the 
Indian Ocean west of Australia, both northwest of Australia. The 
earth observations folks down here on the ground would like to 
have a look at it from space. There's also a tropical storm due 
east of Madagascar that they'd like to have a look at. And on an 
island due east of Madagascar or Union Island, there's a volcanic 
eruption and lava is flowing into the sea and we'd love to have a 
look at that also. At mission elapsed time, 5 days, 16 hours, 50 
minutes, this is Mission Control, Houston.

SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead, Hoot. 

SPACECRAFT Yes Guy, I'm just watching that supply water dump 
and although I've got open talkback on everybody, I don't see 
them dumping. The temperatures are still going up on the nozzle 
and I don't show his quantity starting down any. 

CAPCOM aoger Hoot, we agree. We were seeing the same 

thing and we|re just going to wait a little bit longer here and 
see if anything starts happening. 

SPACECRAFT Okay. 

CAPCOM Apparently w e had the same funny like that happen 

on flight 8 so we're looking at it and while I got you, we see 
the left flight controller power is still on. 

SPACECRAFT Okay, we got it, thanks, Guy. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston, go ahead. 

SPACECRAFT Okay Guy, we got the mass spec program 4 step 3 at 
16 + 54.

tuch left, they'd like you just to go ahead and start fresh 
magazine 4 for the EVA prep. 

SPACECRAFT Okay Guy, that's where we stand. We did complete 
magazine 3, magazine 4 is loaded for the EVA prep. Also on that 
subject, I wanted to find out if the Cinema 360 folk wanted some 

had some preference in what they wanted to shoot with the 
final two magazines. We had a part of one magazine, we've 
reserved for entry, so we have about one full and a slightly 
better part of another magazine and a few major items left to go 
and if they have some preferences, priorities, I'd like to know 
^u at *. J '5 hu ? far ' I ' v ' e taken quite a bit of activity, mainly of 
the middeck crew activity in addition to the PALAPA deploy RMS

q ^^!- a b i fc °, f activit Y> mainly of the middeck crew activity, in 
addition to the PALAPA deploy, RMS, and over the shoulder for the 
pilot (garble) and PLT, with 25 mm. So in short I'd like to know 
their preferences and I can certainly work that. Over. 

Sn P ^ oc n R °9 er ' copy Ron. And did you finish the activities 
on the 25 mm lens scenario? 

SPACECRAFT No Guy, I didn do some, but not all. I'm back on 
(garble) right now. but I do plan to do some 35 mm lens work 
during the EVA and later on in the flight on flight day 8. Over. 

CAPCOM Okpy, sounds good Ron, and we'll try to get an 

answer to you, they would just like to thank you for keeping them 
updated like you've been doing and a reminder they'd like some 
shots during the EVA of MMU translation by their 360 out in the 
gas can. 

SPACECRAFT Oh yes, we plan to do a lot of GAS can work in just 
a few minutes. J 

CAPCOM Roger sounds great Ron. And Challenger, Houston. 

Hoot I ve got a note here on the supply dump attempt. 

SPACECRAFT Go ahead Guy. 

CAPCOM Rog. What happened on flight 8 was we just turned 

everything off and tried again an hour later and it worked. So 
right now the temps are getting up, so we'd like you to go ahead 
and close the supply dump isol valve, turn off the nozzle 
(garble) and go to high on the rad out, outlet temp. 

SPACECRAFT Okay, we'll do that Guy. 

CAPCOM Thanks Hoot. 

SPACECRAFT Okay, and Guy, you want to leave the dump valve, 

itself open, is that true? 

CAPCOM Roger, Hoot, that's affirmative. 

SPACECRAFT Okay, so we've closed the dump isol valve, we're 
going to turn the heater off. 

CAPCOM Roger, thank you Hoot. 

PA0 Mission Control, Houston. That problem with the 

water dump i*> similiar to the one we've seen on STS-8 and they'll 
tollow the same procedure they used on that mission. And wait 
about an hour and try again. We have canceled the 12:30 a.m. 
change of shift briefing with Flight Director Larry Bourgeois, 



STS-41-B AIR/GROUND TRANSCRIPT t315j 040:05:56 2/8/84 F AGE 2 



and a reminder with FVA television coming out of the sky tomorrow 
morning, we're going o cancel the Randy Stone,.. 

CAPCOM ...note for Ron. 

SPACECRAFT Go ahead Houston. 

CAPCOM Roger, Ron, the 360 folks say after you've 

completed all their predefined activities, feel free to qet anv 
shots you think are meaningful. 

SPACECRAFT Okay, I think predefined activites equate to 
middeck scene, flight deck over the PLT's to the (garble) filter 
and that's all I can recall offhand but okay, I'll make a note of 
that, thank you. 

CAPCOM Roger, Ron, we concur with that, what you iust 

said. J J 

SPACECRAFT Okay. 

PA0 Mission Control, Houston. To continue, we've 

cancelled Larry Bourgeois 12:30 a.m. cbange of shift briefing, we 
will cancel the Randy Stone 8:30 a.m. change of shift briefing, 
so the next briefing at the JSC newsroom will be at 11:30 
Thursday morning, building 2 room 135, with John Cox. 

CAPCOM Go ahead, Vance. Challenger, Houston, go ahead. 

SPACECRAFT Roger, in your teleprinter pad here at 5:16:55 you 
have a note A to A6. I guess every reference to A6 assumes we 
still had a vernier jet problem when we were on PRCS, is that 
affirm? So its not applicable here. 

CAPCOM i believe that's correct Vance, but let me check 

with PROP. And Challenger, Houston, Vance, we concur, you should 
go back to the Al DAP per the original cap with the verns are 
working. 

SPACECRAFT Okay, and if they ever hiccup again, we'll keep A6 
in mind. 

CAPCOM Roger, sounds good Vance. 

SPACECRAFT Houston, Challenger.

SPACECRAFT Roger, Houston, note yesterday we were flying over 
Centra. America and it was a fairly clear day, we got a good view 
of a volcano down there.

get a good shot of that. How — could you tell if Costa Rica

the dump enable nozzle heater to OFF OFF and we'll close the 
dump isol valve. 

CAPCOM That's affirmative anr the next step to follow with 

that if no dump, is to perform the waste water dump per the

CAPCOM Hoot, if you have a second, I'd like to continue 

with the supply water dump t roubleshoot . 

SPACECRAFT Okay, yes, go ahead John. You started to say the 
part about if no dump, we go dump enable off isol valve closed, 
go ahead and perform the waste water dump and I think you were 
going to say per message 54 also. 

CAPCOM Roger, you have it, that is correct and let me tell 

you what to do if dump is sucessful. If dump is sucessful with 
the supply water, we would like you to dump tank bravo to 30 
percent. And then take the waste water pump valve enable nozzle 
heater to off. 

SPACECRAFT Okay, I copy. if i get a good dump out of water 
tank bravo, the supply tank, I'm going to dump him to 30 percent 
and I will take the waste water dump enable nozzle heater off. 
Do you do want that taken off when I see that I've got a good 
dump or when I finish dumping water tank bravo? 

CAPCOM Roger, when you see you have a good dump going, 



STS-41-B AIR/GROUND TRANSCRIPT t318j 040:07:40 2/8/84 PAGE 2 



take the heater off, and we'll come back and get the waste water 
after this supply water dump is complete. 

SPACECRAFT Okay, I copy that John, I guess we're trying to use 
a xittle bit of the extra heat maybe from the waste dump to helo 
warm up the supply dump? ^ 

CAPCOM Negative, we were just getting it heated ud in case 

we had to do the other mode.

Mission Elapsed Time. 

PA0 This is Mission Control, Houston. We're in a side 

sun attitude which doesn't contribute to a good signal strength 
through the TDRS due to antenna pointing dif f iculities . The 
attitude was called for in order to provide thermal heating to 
the side of the Orbiter which has the water stowage tank B, for 
bravo, tank valve which has been inoperative due to a — a valve 
which we suspect may be inhibited by a plug of frozen ice. The 
side sun attitude is intended to melt that plug and as yet has 
not done so. We've tried to dump water during this pass and 
were unsuccessful in doing so, accordingly it looks like we'll be 
using the flash evaporators to purge tank bravo again later

INCO is looking at means of providing alternate communications 
methods with the Orbiter right now and we'll stand by to see what 
kinds of success he has, this is Mission Control, Houston.

second. Okay Jerry, go ahead with your procedures. 

CAPCOM Okay Bob, your option, one suggestion is just to 

have Bruce help you get your feet into the stirrups. The second 
option would be to use some string out of the sizing kit to cinch 
down the toes of your boots so that you have some clearance to 
get into the stirrups, over.

really not sure that that would, we could do that. Let me just, 
I'll just fight with it today. Just tell the surgeon to look for

sync up PET. The reason for getting out early is to make sure we 
initiate the first MMU flying with the sun. 

SPACECRAFT Okay, I think the approximate nominal PET was 2200 
hours. We'll get out as soon as we can but not to exceed a half 
hour before that. 

CAPCOM That sounds good to us. And Vance, can you advise, 

do the guys have their biomed circuitry hooked up? 

SPACECRAFT Yes, they sure do. Matter of fact, you ought to be 
able to see it. They're hooked up for about 3 or 4 minutes. 

CAPCOM Okay fine, we're low data rate right now but we'll 

be looking when we get back to high data rate. Thank you. 

SPACECRAFT What do you say we shoot for PET at 21:30? 

SPACECRAFT Want to set up the CAP and cover the checklist and 
all that?

CAPCOM Roger, Hoot. If you're over by LI, we'd like you 

to go ahead now and take the rad controller out temp to normal 
and the FES to off and then we will — then you can go ahead and 
operate the FES per the water survey right with the timeline and 
then later m the day we'll, we'll go back to boiling the water 
with the FES. 

SPACECRAFT Okay, good deal, thanks John, that was a very 
timely call. 7 

CAPCOM Roger. Challenger, Houston, a note on the SPAS. 

SPACECRAFT John, we have the SPAS activated, the RS completed 
and everything's going well with the SPAS. 

°^ P< :? M Roger, understand. You may check that the 3 steps 

at the bottom of page 6-9 in the payload ops checklist are 
completed. 

SPACECRAFT Stand by John, I'll check that. Hey, Houston, yes, 
we got those steps John, we got them long ago. 

CAPCOM Understand, we were just looking at a little bit of 

hazy data on that but thank you for the call. 

SPACECRAFT Okay, John, thanks for looking over our shoulder. 

^h P °c M o Challenger, Houston, a note for you again reference 
tne oPAS. 

SPACECRAFT Go ahead John, ready to copy. 

CVPCOM Okay, we would like you to repeat the 3 steps at 

tne bottom of page 6-9. 

SPACECRAFT Okay, we'll go and do that. 

CA1-COM Roger. 

SPACECRAFT Okay, John, John, I guess in order to do that, 
those are the, the panel closing out the standard switch panel? 

CAPCOM That's taking the SPAS, right over on L12 Hoot, 

taking the SPAS external power to off, and then the panel ACTV to 
off and then the circuit breaker switch power to open. 

SPACECRAFT Okay John, to do any of that, we need to close the 
circuit breaker and do that and I will go and hit those switches. 

CAPCOM Your absolutely correct Ron.

want to set up the CAP, or the checklist, and all that?' You want 
to mark that m the checklist and all that, or what? 

SPACECRAFT Not right now. 

SPACECRAFT Okay. 

CAPCOM Challenger, Houston, Hoot, EECOM would like you to 

do some switches for him on the waste water closeout. 

SPACECRAFT Okay, go ahead John. 

CAPCOM Roger, he'd like you to take the dump valve enable 

heater to on, the dump isol valve of the waste water to close and 
the dump valve to open in that sequence. 

SPACECRAFT Okay. 

CAPCOM Thanks a lot Hoot. 

SPACECRAFT Okay, John, that was turn the heater on first 
check the dump valve closed — give that sequence to me again. 

CAPCOM Okay, take the dump valve heater to on and then the 

dump isol valve to close, then the dump valve to open on the 
waste water. And then we want to stay in that configuration 
until we tell you differently. 

SPACECRAFT Okay, you want to leave the heater running then. 

CAPCOM That's affirmative and we'll turn it off in a 

little while after it's warmed up. 

SPACECRAFT Okay, and John, and if we don't have you and if it 

gets to 300, shall I turn it off? 

CAPCOM That's affirmative Hoot. 

SPACECRAFT Okay, will do. 

CAPCOM Challenger, at your convience, we would like you to 

pertorm the 10.2 cabin maintenance using N2 makeup only. 

^« C ?2J AFT ° kay ' y ° U want an N2 makeu P' we'll get that when we 
can uonn. 

CAPCOM Roger, that. Challenger, Houston, I have a note 

for somebody reference the FES, when you have a second. 

SPACECRAFT Okay, go ahead John. 



STS-41-B AIR/GROUND TRANSCRIPT t323j 040:09:09 2/9/84 PACK 1 



SPACECRAFT Okay John, to do any of that, we need to close the 
second breaker and do that and I will go and hit those switches. 

CAPCOM You're absolutely correct, Ron. 

PA0 This is Mission Control, the RMU systems officer 

indicates that . . . 

CAPCOM Roger, thank you very much and we see the power 

of f . 

PA0 The RMU systems officer reports the data shows that 

the Remote Manipulator System has been activated and rolled out 
of its cradle. Mission elapsed time, 5 days, 20 hours, 10 
minutes . 

SPACECRAFT Houston, Challenger, do you have any TV? 
CAPCOM Negative, we do not. 

SPACECRAFT Okay, got ya. We got a bunch of TVs up and we're 
getting ready to bring the arm out and then bring the SPAS out. 

CAPCOM Challenger, Houston, we are go for TV now. 

SPACECRAFT Okay, got (garble) cooling, Bob, Bruce. It's 
easier this way. 

SPACECRAFT Air ight . 

SPACECRAFT Strings are covered. Wrist rings and waist rings 

are covered. Checked it. Okay, we'll leave the comm the way it 
is for the moment, H20 off, verify that and then it verified 
power SCU, SPAS fan on, (garble) comm VOX, verify both purge 
valves that you have on each suit closed and locked. Okay, the 
arm's coming out and Camera 360's rolling. Put 02 actuator to 
press and check seat pressure 4.2 to 4.4. Okay, go to 02 
actuator IV and I'll time you 1 minute. We'll stop at 1 
minute. Mark, one minute. Very good, we're going to start the 
purge, (garble). Put the actuator to press, then purge valve 
open. 

CAPCOM Challenger, Houston for the flight deck guys. 

SPACECRAFT Okay Jerry. 

CAPCOM Roger, Ron, we'd like you to go over to SPEC 77 and 

read us down the MMU temps if you would, please. 

SPACECRAFT Okay, stand by John. Okay Jerry, the MMU temp left 
for the port +46? starboard, +41; right, +38 for the port; +42 
for the starboard. Over.

CAPCOM Rr... ; {on, could you just read us down the 4 

columns there on both of them, please. 

SPACECRAFT Okay, we'll get the 4 columns. The port column, 
you have a +95, +100, +46, +39, +40, +36, +59. For the 
starboard, +109, +111, +41, +43, +40, +40, +59. Over.

Houston for Bruce and Bob. y ' 

SPACECRAFT Houston, Challenger. Okay go ahead, Jerry. 

CAPCOM Okay Bruce, we listened to some of the ICOM debrief 

after the first EVA. We were not able to determine if you, 
Bruce, had ever got any hard docks with the T-pad, over. 

SPACECRAFT That's affirmative on the CESA, second dock was a 
hard dock and I went into the (garble) stabilization mode, fired 
roll thrusters to verify that it was on there and it really 
rocked you back and forth pretty violently and it held very 
nicely. 1 

CAPCOM Okay, copy that and do both of you ... 

END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t324j 040:09:22 2/9/84 PAGE 1 

SPACECRAFT I went into the stat stabilization mode fired, roll 
thrusters to verify that it was on there and I really rocked it 
back and forth pretty violently and it held very nicely. 

CAPCOM Okay, copy that and do both of you intend to do at 

least one of those today? 

SPACECRAFT Yes, we'll probably get at least one up on the 
SPAS. 

CAPCOM Okay, that sounds good. 

SPACECRAFT I don't know for me, Jerry. It that takes time for 

the docking, so. 

CAPCOM Roger, Bob, I under... 

SPACECRAFT (garble) 

CAPCOM Understand. We want to make sure we at least get 

one, it would be good if each of you had one. 

SPACECRAFT Yes, understand. 

SPACECRAFT And Houston, Challenger. 

CAPCOM Go ahead, Vance. 

SPACECRAFT Thought I'd bring you up to date. We're in the 8 
minute purge, they'll be going into prebreathe fairly shortly. 
Since we're venting gas into the cabin, I don't suspect we'll 
need to pump it up with N2 in addition, but, maybe you can take a 
look after the purge is finished to see. 

CAPCOM Okay, we won't be with you quite that long, Vance, 

we're 4 minutes to LOS. And Challenger, Houston, if you're 
ready, we'd like to go ahead and perform the comm check before we 
go LOS. 

SPACECRAFT Roger, stand by. Okay, how much time you got 
before LOS? 



CAPCOM 



It says 3 and a half minutes, Vance. 



SPACECRAFT Okay. Bruce, put your comm to bravo, Bob, yours to 

alpha, then I'll turn off the switch and we'll make a comm cheek. 

SPACECRAFT Okay, Houston, this is EV2 in mode alpha. Bow do 
you copy? 

CAPCOM Roger, Bob, got you clear, somewhat in the mud but 

readable. 



STS-41-B AIR/GROUND TRANSCRIPT t324j 040:09:22 2/9/84 PAGE 2 



SPACECRAFT Okay, Houston, this is EV1, I'm in mode bravo 
today. 

CAPCOM okay, Bruce, you are loud and clear, Bob is still 
somewhat down. 

SPACECRAFT Okay, how about now. 

SPACECRAFT Please, please make another check with Bob, I 

didn't have the airlock audio power off when he made his check. 

SPACECRAFT Okay, Jerry, how do you copy now. 

CAPCOM Okay, Bob, that sounds great, thank you. 

SPACECRAFT Okay. 

SPACECRAFT Okay, and how are you reading me now, Jerry. 

CAPCOM okay, Vance, I got you loud and clear also. 

SPACECRAFT Yes, I turned airlock audio power back on, and good 

CAPCOM Roger, that. 

SPACECRAFT You want us to go back to the hardline Vance? 
SPACECRAFT Yes, it's probably a good idea. 
SPACECRAFT Okay. 

SPACECRAFT And you're coming up on 6 minutes of purge, a 
couple or 3 minutes more, then will go to prebreathe. 

SPACECRAFT Houston, Challenger. 

CAPCOM Go ahead. 

SPACECRAFT A little bit of RMS information, we get. When I 
was maneuvering the arm up to overhead the SPAS, it wasn't 
responding exactly the way 1 nought it ought to and we got enab 
«J?a£ S!L 5 S 1 ? 0 ^? 1 *^ and on SPEC 96, we have enab STA in 
wrist yaw. And looking out the window, it may be that that was 
what I was seeing was that the wrist yaw I don't think was 
following what we were asking for. 

CAPCOM Okay, Hoot, we concur with that, we'd like you to 

perform MALF 13.1 Charlie. 

SPACECRAFT Okay, that's where we are. 



STS-41-B AIR/GROUND TRANSCRIPT t324j 040:09:22 2/9/84 PAGE 3 



And we're 40 seconds to LOS guys, Hawaii next at 21 



See you in Hawaii. 
Hey, Jerry, do we still have you? 
Just barely. 

This is Mission Control, Houston. We're LOS from 
TDRS, we'll pass over the Yarragadee sites but because of the UHF 
configuration for the EVA, we will not have UHF communications 
through Yarragadee. Next AOS will be through Hawaii on the 
ascending node of orbit 95, in about 35 minutes. And RMU systems

about 35 minutes. And the IMU systems officer here in the 
Control Center shows data indicating that the crew has the Remote 
Manipulator System heated up and operating. Suit checkout, 
voltage levels, pressures, communications check, all going well. 
And the EVA crew looks to be about 50 minutes ahead of their 
timeline so far and anticipating EVA may begin about 30 minutes 
earlier than originally planned. 

SPACECRAFT Let's make a check on what you're taking out, TV's 
and, it's in our bag. We have the 35 mm MMU camera with cable. 
Okay, it's there, 35 mm handheld camera with brackets, MMU

CAPCOM Challenger, Houston in Hawaii. 

SPACECRAFT Hey Houston, we have you loud and clear and we're 
holding to go out until we've got the ... 

CAPCOM Roger. 

SPACECRAFT Okay, yes, Jerry. With respect to the RMS, we've 
been holding since we last talked to you which was a long time 
ago. We have gone through MALF 13.1 Charlie, went through box 1, 
4, 7, 8. Box 16, the answer was a no, the (garble) does not 
drive in single, and we got to box 17 and we're holding on that 
caution before going to block 21, if you want us to do that. 

CAPCOM Okay, stand by. Challenger, Houston, for Hoot. 

SPACECRAFT Go ahead, Jerry. 

CAPCOM Okay, I've got a series of switch throws for you 

here. What we're essentially going to do is cycle power on the 
arm. First one is RMS select to off, RMS power to off, power to 
primary, select port, SPEC 94, item 5 execute and cancel safing.

we'd like you to cradle it please. We'll see you at TDRS in two 
minutes . 

SPACECRAFT Okay, and Jerry we'll cradle the arm, that's what 

we were expecting to hear, I'm afraid. 

CAPCOM Roger, that. 

SPACECRAFT Okay, how do you read, Bob? 

SPACECRAFT Loud and clear. 

SPACECRAFT And I read loud and clear. 

SPACECRAFT John. I'll look around once more and make sure 
there anything loose. 

SPACECRAFT Bruce, what does this battery bag attach to? 

SPACECRAFT It's attached to your wrist tether and also it's 

snapped to that strap on the top of the arm. It won't go 
anywhere. 

SPACECRAFT Okay, Bruce and Bob, I don't see anything in the 
airlock that shouldn't be there, do you? 

SPACECRAFT No. 

SPACECRAFT Looks good. 

SPACECRAFT Okay, I'm going to close up the inner hatch, have 

a good EVA there.

PA0 This is Mission Control, Houston. There's an 

apparent failure on the RMS wrist yaw motion capability which 
has. . . 

SPACECRAFT Would you move that battery until I see where my 

foot is going to go. Thank you. 

PA0 That failure has induced the systems officer here 

to instruct the crew to cradle that arm and RMS operations for 
thio EVA are accordingly in severe jeopardy unless some kind of 
workaround can be devised. The EVA crewmen are in the hatch and 
they're transmitting on their UHF. . . 

SPACECRAFT Okay, I'll start my feet out the door here and i 

want to end up facing the inner hatch door. 

PA ° With those EVA crewmen in the airlock and 

transmitting on UHF, we'll get constant communication from them 
as an artifact of this comm configuration. 

SPACECRAFT (garble) looks good.

PAO This is Mission Control, Houston. Once again, RMS 

checkout operations reveal the failure ... 

SPACECRAFT Thank you. 

PAO A failure in the RMS wrist joint and the range of 

motion for yaw mechanism. That failure has induced the Control 
Team to instruct the crew to cradle the arm and RMS operations 
for the day's EVA are in jeopardy. 

SPACECRAFT Houston, how are you reading Challenger?

SPACECRAFT Copy. 

SPACECRAFT Bruce have you translating to the slide wires you 
have and free tether and going to the starboard MMU, and Bob 
translating to slide wire to the SESA and stow the flashlight. 

SPACECRAFT (garble), probably a result of operations 
(garble). Oh hey, can you guys see out the window? One of our 
operational slide wire brackets has come unpinned. 

SPACECRAFT It sure has.

CAPCOM Roger Bruce, we can see on the ground too, is the 

pip pin there? 

SPACECRAFT Pip pin is there and I will reinstall it but it's 
still a little startling. 

CAPCOM we agree with that.

SPACECRAFT Hello, Vance, we're taking a slight detour. I'm 
going to get Bruce the hammer. 

SPACECRAFT Okay. 

SPACECRAFT (garble) . 

PA0 This is Mission Contol, Houston. Now McCandless 

repairing the slide wire articulating arm. The slide wire itself 

is secure and not in any jeopardy. This . . . 

CAPCOM Houston for Bob. 

SPACECRAFT Go ahead, Jerry. 

CAPCOM Roger Bob, we think it'd probably be a good idea 

for you after you get Bruce configured with his T-pad to check 
all 4 corners on the slide wires and make sure those pip pins are 
secured. 

SPACECRAFT Okay, I can do that. 

PA0 That Articulating Arm positions the slidewire and 

the slide wire is secure, not loose. And that doesn't translate 
into any safety problems for the EVA astronauts but as to why 
Bruce McCandless referred to it as startling was because that 
could have caused a problem with closing the payload bay doors. 
And the plan is now to check each of those arms to assure there 
rigidity and solidity. 

SPACECRAFT The hammer the only thing you're going to need, 
Bruce? 

SPACECRAFT Yes, I think so.

You 1 re inside the bay so no problem. 

SPACECRAFT Okay. Okay, looking over the T-pad, after we 

reconnected to primary last night, everything looks secure. 

SPACECRAFT Houston, Challenger, we just had the manifold R5 
jets take off again, you had said previously we can reset them 
(garble) and press on the verniers? 

CAPCOM Negative, Hoot, we don't want you to do that, 

there is no power to those jets at this time. We would like you 
to go tail only, low Z. 

SPACECRAFT Okay, we'll go tail only in low Z.

SPACECRAFT Good. 

SPACECRAFT Yes, but. 

SPACECRAFT I'm working on the electrical connnector now. 

CAPCOM And Challenger, Houston for Bruce. Bruce, you may 

want to set your TV in one switch position and wait a couple of 
minutes to see if the signal, I mean the battery conditioner 
circuitry works. if it doesn't work in that position, cycle 
(garble) and see if it works in that one.

to (garble) . 1 



CAPCOM 
please. 



Okay Ron, I didn't copy all that, say again, 



SPACECRAFT Saying that when I turned the SPAS TV on earlier, 
my command to turn them off must have — may have failed which 
may block Bruce out. 

SPACECRAFT No, I'm not getting a green light here. 

SPACECRAFT Okay, camera delta is reinstalled. 

CAPCOM Okay, copy that. Bruce, EVA says that those 

batteries may have changed state overnight so you may have to 
repacify them. 

SPACECRAFT Okay. It came right up when I turned it on last 
night. Okay camera delta should be back in operation, you can go 
ahead and put the circuit breakers in give it a try. 

SPACECRAFT Bruce, your batteries are bad. Why don't you take 
your switch off. 1 

SPACECRAFT Hey Ron, I can't tell whether my switch is on or 
off. I just have to leave it in one position for awhile, just 
like a push button. Camera delta is back installed. I'd like 
you to close the circuit breakers in it and see if it works. 



SPACECRAFT Okay, we'll try it. 



STS-41-B AIR/GROUND TRANSCRIPT t334j 040:10:58 2/9/84 PAGE 2 



SPACECRAFT Okay Bruce, we don't have any video yet on camera 
delta. Not yet, Bruce. 

CAPCOM Challenger, Houston for Vance or Hoot. 

SPACECRAFT Hi Jerry. 

CAPCOM Roger Vance, we'd like you to go to FS10-1, that's 

the aft flight station configuration sheet and configure for loss 
of verniers. 

SPACECRAFT Okay, 10-1, FS. 

CAPCOM Roger that and you've got 8000 lbs of prop so we 

don't have to worry about using norm z or low Z's rather. We're 
48 seconds to LOS here, Yarragadee next at 22:12. We'll probably 
only be able to hear you there. Hawaii at 22:37, configure Ku to 
stand by, please. 

PA0 This is Mission Control, Houston. We're LOS 

through the TDRS system. We've had a failure with vernier jets 
on the vehicle which has caused the Mission Control Team to 
advise to select aft vernier jets for attitude control. We'll 
have acquisition again in 8 minutes. Voice only through the UHF 
station at Yarragadee, at mission elapsed time, 5 days, 22 hours 
and 4 minutes. The delta camera has been reinstalled but initial 
checks showed no joy in getting an image from it. The next item 
on the checklist will be preparation and checkout of the 
starboard MMU, our Man Maneuvering Unit, to check its condition 
to verify its battery level and then prepare it for the day's 
test objective. AOS in 7 and 1/2 minutes at MET, 5 days, 22 
hours, 4 minutes, this is Mission Control, Houston.

SPACECRAFT No, we don't have that dump going, Bob. I think 
that's just some residual. 

SPACECRAFT Okay. Okay, copy. (Garble) Bruce, and I guess yo 
got your— and your sublim er working okay. Is that right? 

SPACECRAFT (Garble) what , a drying out (garble)? 

Th i s is Mission Control, Houston. We're about a 
minute away from acquisition through Hawaii. According to the 
timeline, Bruce McCandless should be preparing the starboard MMU 
donning and checking out that instrument while Bob Stewart is 
preparing and unstowing the trunnions and attachment device, 
which, subsequently, would be installed upon the McCandless MMU, 
and we'll have voice verification through Hawaii to see how 
they re progressing relative to the timelined activities. We're 
less than a minute away from acquisition at 5 days, 22 hr, 37 
min, Mission Control, Houston. 

SPACECRAFT That's affirm, Bruce, they're both out now. 

SPACECRAFT I thought I saw the pressure gauge lights go off 

CAPCOM Challenger, Houston. Hawaii for 8 min. 

SPACECRAFT Roger Houston. A little summary. We have 
operation of camera D now. Of course, it still has the same 
problem in trunnion, but we have a good picture, and we can move 
it back and forth. The repair was accomplished inserting the pij 
pin on the slidewire bracket. Bruce is on the starboard MMU 

checking it out. Pressure on each side is 2600 psi. Each 

Bob progressed down to the end of the arm to the end effector, 
did that task, he'll report to you on it, and, finally, both 
crewmen have had a sublimater press message. They were able to 
restart and each has sublimater pressure now of 2.6. 

CAPCOM okay, Vance. We copy all that. Thank you. 

5*° This is Mission Control, Houston. There'll be no 

TV through Hawaii, but we will get images when we acquire TDRS. 

SPACECRAFT (Garble) on the outside drivers. Did you ever see 
the power come back, and second, do you want us to hake the 
driver switch off. We left it on. 

CAPCOM Roger, Hoot. We'd like to leave the driver switch 

on and the power is still off.

TDRS. Looks like the temps for the dump won't get up until 
LOS. I've got a two- step procedure for you whenever you're 
ready to copy. 

SPACECRAFT Okay, I'll take that. 

CAPCOM Okay, after you get the FT A there at 300 degrees, 

we'd like you to take the supply water tank bravo inlet valve to 
close and then dump tank bravo to 20%. Of course, you'll have to 
use the dump isol valve for that. 

SPACECRAFT Okay, Guy, copy. We're going to get to 300 
degrees, get the FTA, take the tank inlet valve closed and then 
dump tank bravo to 20% using, of course, the isol valve. 

CAPCOM Roger and we'll open up a tank B inlet valve once 

we get tanks char lie and delta topped off. 

SPACECRAFT Okay, copy. 

PAO Mission Control, Houston. Thus far in the crew's 

morning, they have done an IMU alignment, cooked a little 
breakfast, or are in the process of cooking some breakfast and 
they're working with dumping waste water tank B, bravo, and 
they'll wait until the temperature on that sensor aboard gets to 
300 degrees in a solar bake and then they'll go ahead and try to 
dump it. Mission elapsed time, 6 days, 17 hours, 10 minutes,

CAPCOM Challenger, Houston, we're 2 minutes 'til LOS TDRS, 

see you at Yarragadee at 28. 

PAO Mission Control, Houston. Today's activities 

aboard the Challenger primarily concerned with cabin stowage, 
preparation for entry early Saturday. There will be a press 
conference with the crew at approximately 5:51 a.m. this 
morning. And if all goes as planned on today's updated CAP, we 
should see a KSC landing tomorrow, if we do get the nominal 
landing, at right now 7 days, 23 hours, 19 minutes and 4

SPACECRAFT John, so far that dump doesn't appear to be 
working. 

CAPCOM Challenger, Houston, we agree. We don't think it's 

working either. 

CAPCOM Challenger, Houston, we'd like you to go ahead and 

close the dump isol, close the dump valve and turn the heater 
off. 

SPACECRAFT Okay John, close the dump isol and this time we 
want to close the dump valve in addition and turn the heater off. 

CAPCOM That's affirmative. 

SPACECRAFT Okay, that's done. 

PA0 Tn i s is Mission Control, Houston, still unable to 

dump water from the supply tank bravo, presumably because of a 
plug of ice between the dump valve and nozzle. All sorts of 
thermal measures taken to try to remove or reduce that plug of 
ice and none successfully. Mission elapsed time is 6 days, 18 
hours, 47 minutes and they have another 5 and 1/2 minutes 
remaining in this TDRS pass, this is Mission Control, Houston. 

CAPCOM Roger, go ahead. 

SPACECRAFT Hey John, the HRM deactivated at 18:47. 
CAPCOM Thank you very much, Bob. 

CAPCOM Challenger, Houston, we're going LOS TDRS in a 

minute and a half. See you at Yarragadee at 19 plus 00. 

CA 5 C( ?*L . Challenger, Houston's with you at Yarragadee for 7 
and 1/2 minutes. 

SPACECRAFT Roger, you (garble) loud and clear (garble). 

CAPCOM Roger, and you're loud and clear also. 

PA0 t This is Mission Control, Houston. Signals 

transmittal will improve markedly over Yarraaadee. That initial 
concact was with the Orbiter just under 3 degrees elevation over 
the horizon and maximum elevation during this Yarragadee pass 
will be at 80 degrees. So the Challenger will pass almost 
directly overhead at the Yarragadee station. 

CAPCOM Challenger, Houston. We just shipped a weather 

teleprinter message up to you. We'll go LOS Orroral at 19 — in 
30 seconds. See you TDRS at 19 plus 36. 



STS-41-B AIR/GROUND TRANSCRIPT t403j 041:07:41 2/10/84 PAGE 2 



SPACECRAFT Okay Houston. 

Ph0 Th i s is Mission Control, Houston at 6 days, 19 

hours, 16 minutes mission elapsed time. While we were AOS over 
Orroral, we were able to see that the Challenger had maneuvered 
to a burn attitude in order to effect the reaction control system 
development test objective with a firing due to occur at ~ in 12 
and 1/2 minutes at mission elapsed time 6 days, 19 hours, 30 
minutes. Challenger on its 109th orbit of the earth on the 
ascending node. We will reacquire voice through the TDRS system 
in 19 minutes, so this RCS burn will occur in the blind. We'll 
stand by to read the effects of that burn when we come AOS. At 6 
days, 19 hours, 17 minutes, this is Mission Control, Houston. 

PA0 This is Mission Control, Houston, we'll be AOS just 

a moment or two with voice through TDRS. And learn of the 
results of that RCS burn, it's mission elapsed time, 6 days, 19 
hours, 37 minutes, this is Mission Control, Houston. Data 
indicates the test looked good.

CAPCOM Challenger, Houston is with you through TDRS. We 

would like to see you go ahead and terminate the interconnect and 
go straight feed. 

SPACECRAFT Okay, that was going to be the question I had for 
you, John. So, we'll go ahead and do that. 

CAPCOM Roger that, 

SPACECRAFT And John, understand this was an OMS feed DTO so we 
didn't really trim all the residuals down to 0 because I reached 
the fuel that I was supposed to go to through the interconnect. 
Actually I went a bit over it, I got the 5,0 instead of the 4.6. 
And so we did not trim out all of the residuals. 

CAPCOM We copy that, Hoot, and it sounds real good to 

us. We're happy with that. 

CAPCOM Challenger, Houston, you can go ahead with the 

maneuver now if you want. 

CAPCOM And Challenger, Houston, we're standing by for the 

FCS checkout when ya'll get on to it. 

SPACECRAFT Okay, we're starting on it. We're getting the 
switches set up right now. 

CAPCOM Challenger, Houston, we're handing over to MILA to 

get high data rate. 

SPACECRAFT Roger. 

p AO Tl is is Mission Control, Houston. The crew is a 

little bit behind the timeline, we're standing by to watch 
checkout of the flight control system, the procedure usually done 
the day before entry to make sure all the flight control services 
and APU systems are operating adequately. And we're watching 
data now to see when the crew fires up auxilliary power units 
which should be forthcoming. Mission elapsed time is 6 days, 19 
hours, 47 minutes, this is Mission Control, Houston. 

CAPCOM ... with good high data rate data. 

SPACECRAFT Roger, we're in the middle of the G2 to 8

SPACECRAFT Okay for part 1 of the FCS checkout, we're in DAP 
A6, is that good? 

CAPCOM Stand by 1, Vance. I'll try to get you an answer, 

we've been discussing that. 

CAPCOM Challenger, Houston, Flight has decided that we 

have the consumables, you can go ahead and press ahead. 

SPACECRAFT Okay and we just got a poll fail on CRT2 that we're 
looking at. 

CAPCOM Roger, we see that and are looking at it, also. 

SPACEC AFT John, I had noticed on CRT2 too, about half an hour 
or 40 minutes ago, that the DEU flag was tripped on it and one 
reset and that could account for it, like we were briefed on 
preflight, which was a DU. 

CAPCOM Roger, copy, Hoot, thanks a lot. 

SPACECRAFT Okay, we regained it by cycling power and 
reassigning . 

CAPCOM Roger, that's good news. Challenger, Houston, 

you're go to proceed with the FCS checkout.

SPACECRAFT John, on step 2 where it has me verify no under APU 
hydraulics and water flow it says (garble) your down errors. I 
don't have any up errors or down errors, but I've got a bunch of 
lower limits, are those okay?

SPACECRAFT Okay, Houston, how much time do we have before LOS? 

CAPCOM Roger, we have about 2 and a half minutes. 

SPACECRAFT Okay, and then when's the next AOS? 

CAPCOM Roger, the next one's at Dakar in about 7, but 

Flight would like you just to go ahead and we'll get any of the 
other data we need on the dump. 

SPACECRAFT Okay, we were reading ahead a little bit but we'll 
just jump right into it then. 

CAPCOM Roger, that.

CAPCOM I'm not sure we did, Vance, if you could report 

what you saw, we have low data rate. 

SPACECRAFT Okay, we're going to APU shutdown. 

SPACECRAFT Yes, John, it all looks fine and we're on step 6 
now.

Okay, we'll start with the plus X on the middle of 
Roger, that. 

John, we completed the hot fire, how did it look? 
Roger, it looked real good to us, Vance, thanks a 



SPACECRAFT It looked good to us. We, we've seen no 
anomalies. We did have just one nit to mention in the prior 
check which we'll give you in a minute. 

CAPCOM Roger, understand. 



SPACECRAFT Houston, Challenger. 
CAPCOM Roger, go ahead. 

SPACECRAFT Yes, John, we have out of the controller 
checkout, we have a real nit for you but during the high test on 
the dedicated controllers, commanders (garble) nautical miles 
still. We are at 305,000 and the pilots read 307,000 instead of 
300,000. Like I say, it's kind of a nit. 

CAPCOM Roger, understand. 



PA0 This is Mission Control, Houston. That discrepancy 

that Challenger Pilot Hoot Gibson reported is identical to one 
which made itself apparent during STS-8, with the same vehicle. 
That bias is not a hard bias, it remains constant all the way 
down, it reduces proportionally to level, that is, they consider 
it insignificant at lower levels. 



STS-41-B AIR/GROUND TRANSCRIPT t407j 041:10:24 2/10/84 PAGE 1 

PA0 Made itself apparent during STS-8 with the same 

vehicle. That bias is not a hard bias, it remains constant all 
the way down, it reduces proportionally to level, that is they 
consider it insignificant at lower levels. It's Mission Elapsed 
Time, 6 days 21 hours, 24 minutes, and the flight control system 
checkout is just about complete. 

CAPCOM Challenger, Houston, to get back to you on your nit 

on the flight control system check. We concur it is a nit, on 
flight 8, we saw the same phenomenon and our experience showed 
that it wasn't a factor and all as we got down to lower 
altitudes. 

SPACECRAFT We agree, I think it's rather fantastically great 
to go through a test, two tests like that and that's the only 
thing we can find wrong. 

CAPCOM Roger, that, Vance. 

SPACECRAFT Vance figured we had to tell you something, or else 
you'd think we didn't really... 

CAPCOM Understand, Hooter. Challenger, Houston, I have a 

couple of questions for you if this is a good time for you. 

SPACECRAFT Sure, go ahead. 

CAPCOM Roger, Vance. First of all, when you got the CRT 2 

BITE, did that occur in conjunction with a major function switch? 

SPACECRAFT Yes, I'll let Hoot explain it, because he was 
moving the switch at the time. 

SPACECRAFT Yes, John, (garble) earlier today, I wrote a note 
on my kneeboard that the DEU find was tripped on CRT 2 and then I 
thought that I saw one little flicker out of him later on, but 
what caused the guy to go poll fail was switching from GNC to SM. 

CAPCOM Roger, I owe Flight a coke. 

SPACECRAFT You want me, you want me to report something 
different? 

CAPCOM And Hoot. . . 

SPACECRAFT Houston. 

CAPCOM Go ahead. 



SPACECRAFT 



Go ahead. 



STS-41-B AIR/GROUND TRANSCRIPT t407j 041:10:24 2/10/84 PAGE 2 



CAPCOM Roger, DPS says that that's just a timing problem 

and our experience has shown that that means the CRT will be 
okay, you can expect it to be okay. Challenger, Houston, did you 
copy what I told you DPS felt about that CRT 2 BITE? 

SPACECRAFT We heard you say that it was just a timing problem, 
then you dropped out. 

CAPCOM Roger, Vance, it was just a timing problem, we have 

had experience with that before, we believe that your CRT number 
2 will be — will work just fine. 

SPACECRAFT That's great and let's see John, you'd like to see 
us sit in this attitude even though we're done a little early til 
21:45, is that right, in this inertial attitude? 

CAPCOM Stand by, Vance, I'll get you an answer, we've been 

talking about that here the last five minutes. Challenger, 
Houston, we want to stay in this attitude and we would like you 
to stay in it until we tell you to initiate track to the next 
maneuver because we need to update the target TDRS state. 

SPACECRAFT Okay, we'll stay at this inertial attitude. 



CAPCOM Roger, that. And if somebody is back near the RMS 
panel, I have a switch back there I'd like them to look at. 

SPACECRAFT Go ahead. 

CAPCOM Roger, confirm... 

SPACECRAFT Go ahead, John. 

CAPCOM Confirm that the RMS break switch is in the on 
position. 

SPACECRAFT Okay, break switch was in the off not in the on 
position. 

CAPCOM Understand it was in the on position. 

SPACECRAFT Negative, the break was in the off position. Just 

switched it to the on position. 

CAPCOM Understand and you switched it to the on position, 
thank you. 

SPACECRAFT That's affirm. 

CAPCOM Challenger, Houston, while I'm talking to you, we 
had two switches that EECOM is interested in. We see your cabin

help boil some of the water off, if you could take the rad 
controller out temperature to high. 

SPACECRAFT It's in high. 

CAPCOM Thanks a lot. 

CAPCOM Challenger, Houston. Hate to bother you again, but 

evidently when you loaded your TFL 161, it didn't take, so if you 
would reload that again for us, we would appreciate it. That is 
TFL 161. 

SPACECRAFT Okay. I'll give you a 161 over again, John. 
CAPCOM Thanks a lot. 

SPACECRAFT And we, yeah, we have it showing on SPEC 62, John, 
but I'll go ahead and do another one. 

CAPCOM Roger. We understand. Our data shows that you did 

it, but for whatever reason, it didn't get latched, so if you 
could do it again, we would appreciate it. 

CAPCOM And Challenger, Houston. Sorry to bother you 

again, but we have a new TDRS target state vector onboard now, so 
you are go to initiate the maneuver on time per the CAP. 

SPACECRAFT Copy. Initiate the maneuver at 45 past the hour. 

CAPCOM Roger that. 

SPACECRAFT Okay, John, you should have the new reloaded format 
161 now. 

CAPCOM Understand. I'll let you know if it's working. 

And Hoot, the 161 format is now downlisting. Thanks a lot.

SPACECRAFT Houston, Challenger. Do you read? 
CAPCOM Roger, Bruce. Loud and clear. How us? 

SPACECRAFT You had a question? 

CAPCOM Yes, if you have a minute, Bruce, we would like to 

know, have you been able to close and engage the door latches on 
MD23R? 

SPACECRAFT Affirmative. Here on middeck 23 Romeo is secured 
for entry. 

CAPCOM Thanks a lot, Bruce. 

SPACECRAFT (Garble) 
SPACECRAFT Houston, Challenger. 
CAPCOM Roger. Go ahead. 

SPACECRAFT John, do you know if there's supposed to be any 
volcanic activity just to the north of our ground track at about 
our present position? 



CAPCOM I'll check on that for you, and get back to 



you. 



SPACECRAFT Okay. It may not be, but the reason I'm asking is 
that looking up a ways to the north, there's an island that 
there s a smoke cloud rising off of it, and it doesn't appear to 
be just an atmospheric cloud formation. It kind of looks like 
it's rising up off the island. 

CAPCOM Roger. Copy that. I'll get back to you. We'll 

check with weather. 

SPACECRAFT I should add, it's far enough away that I can't be 
really sure. 

CAPCOM Roger . 

CAPCOM Challenger, Houston. I have a little CAP 

adjustment for you after the press conference when you're ready

CAPCOM Roger, after the press conference is completed and 

before the TV is deactivated, we would like you to perform the 
PDRS ops checklist unberth SPAS, step 2 on pages FS 3-3 and 3- 
4. Then we would like to see live TV of the SPAS disconnect 
using the best camera that you think you need to do that to view 
the umbilical mechanism. Finally when you are complete with 
that, you can deactivate the TV per the CAP and then maneuver as 
soon as possible to minus ZLV. 

SPACECRAFT Okay, John, we've got, after the press conference 
but before we've deactived the TV, go to the PDRS checklist and 
the unberth SPAS section, perform FS 3-3 and 3-4, set it up for 
live TV on the umbilical disconnect and when we're complete, 
deactivate the TV and go back to minus ZLV HF.

Press. 

RECER To Bruce McCandless and Bob Stewart, as operators 

of the MMU. . . 

SPACECRAFT Okay, just a minute, first let's get the crew in 
here, come on in. Okay, we're all here. 

RECER To Bruce McCandless and Bob Stewart. As operators 

of the MMU, you saw and felt things never before experienced, 
you've given your report as pilots and as astronauts, can you 
tell us please in more human and perhaps even poetic terms what 
you saw and felt while flying the MMU. 

SPACECRAFT Well, in human terms, I was most impressed by the 
spectacular panorama that I could see through the wide field of 
view afforded by the helmet. I recall seeing the east coast of 
Florida go by and the view was simply spectacular. The sensation 
of floating freely in the MMU and flying was not a great deal 
different from the sensation of floating freely here inside the 
Orbiter but it was one of realizing that you had control over 
where you were going and of your maneuvers. So I was very 
pleased both as an engineering test pilot with the performance of 
the unit and very pleased to have had that personal experience. 



STS-41-B AIR/GROUND TRANSCRIPT t411j 041:11:39 2/10/84 PAGE 3 



SPACECRAFT I guess my impressions were of the immensity of the 
entire universe...

... very pleased both as an engineering test pilot 
with the performance of the unit and very pleased to have had 
that personal experience. 

SPACECRAFT I guess my impressions were of the immensity of the 
entire universe, of looking around here and just seeing the 
circle of the earth, the horizon thinking what a beautiful earth, 
what a beautiful flying machine and what a lovely MMU. 

PAO Martin Gaines, CBS News. 

MARTIN GAINES (CBS NEWS) To the same gentlemen, I'd like to ask 
whether there was any sensation whatsoever that you were really 
drifting along at over 17,000 miles an hour. Did you feel that 
you were moving rapidly through space? 

SPACECRAFT Feel is not the right word. You certainly can look 
down at the ground and tell that you're going very fast. I guess 
it depends where your vision is focused. If you're looking down 
at the ground, the speed is obvious. If you're focusing on the 
Orbiter working in close to the bay, then your mind is 
transformed from going 17,000 miles an hour to going 1 or 2 feet 
in a second. 

PAO Jules Bergman, 

SPACECRAFT I guess the closest analogy that I could make, 
which I think I mentioned over the air to ground link, was of 
being in an observation type helicoptor or other bubble nose 
airplane going at Mach 25. It was really spectacular. The 
ground and the continents and the oceans just sped by you with 
outstanding visibility. 

PAO Jules Bergman, ABC News. 

JULES BERGMAN {ABC NEWS) For Bruce and Bob Stewart again. How 
well did the MMUs operate during the free flight and would you 
pronounce them ready for the solar max mission? 

SPACECRAFT They operated absolute superbly and very much like 
the simulator that we trained on in Denver and yes, in my 
opinion, they're ready for the solar max flight. 

SPACECRAFT Yes, I concur. 

PAO Olive Talley, UPI 

OLIVE TALLEY (UPI) For Vance and Hoot. Are you ready for a 
Cape landing tomorrow? Have you gotten an updated weather report 
and have you been given the go ahead for a cape landing tomorrow? 



SPACECRAFT Sort of in reverse order. No, we haven't, have not 



STS-41-B AIR/GROUND TRANSCRIPTS t412j 041:11:57 2/10/84 PAGE 2 



been given a go ahead and as far as an update, no we have not had 
one today. We understood yesterday that Cape weather was looking 
good. We're definitely ready. Just a question of will the 
weather be ready. 

PAO Roy Neal, NBC 

ROY NEAL (NBC) Okay, this is for Ron McNair. Ron, can you give 
us a handle on how well that arm, the RMS, performed and the 
cameras. It seemed down here as if you were constantly having 
trouble with both. 

SPACECRAFT The arm performed very well. I did not have any 
trouble with the arm itself during the first EVA. The camera on 
the arm, I take it if that's the one you're speaking of, did have 
some difficulties late in the second EVA. But during the first 
EVA, while we were doing the manipulator foot restraint work, 
there were really no problems. We did have a failure later on 
during the second EVA, but while the arm was working well, it 
functioned quite properly. 

NEAL I was referring to the fact that we saw cameras 

such as camera delta which were out. We saw a fix made on a 
helmet camera by beating on it. I'm referring to the fact that 
the arm was unable to rotate the SPAS during the second EVA. 
That's what I'm talking about, Ron. 

SPACECRAFT Okay, yes, we did have a few problems with the 
payload bay cameras. Camera delta was unable to have any tilt. 
We did have some slow pan capability. Cameras on the aft 
bulkheads were out of view of most of the activity taking place 
in the forward end of the payload bay. And the RMS elbow camera 
eventually had some problems. It was giving us so.Tte good views 
earlier in the second EVA. So we did have a few camera problems 
but we did maintain enough capability to downlink some qood TV, I 
think. 

PAO John Getter, KHOU television. 

JOHN GETTER (KHOU) For the Payload Specialists, Bruce and Bob 
in particular. Now that you have done your MMU test, now that 
you have done the refueling tests, how difficult or easy do you 
think it's going to be for you and your cohorts to go permanently 
into the satellite repair business. 

SPACECRAFT Well actually, we're along on this one as Mission 
Specialists. We had Payload Specialists on the last flight. The 
completion of the MMU checkout and refueling DTOs will allow us 
to capture, stabilize and service satellites that are in an orbit 
that is currently reachable by the space shuttle or that operate 
at length from ...END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t413j 041:12:01 2/10/84 PAGE 1 



- - (garble) stabilize and service satellites that 
are in an orbit that is currently reachable by the Space Shuttle, 
or to operate at length around something like the Space Shuttle, 
or to operate at length around something like the space station 
whose construction we have now started. So yes, I would say it 
has very definitely opened the door to on-orbit servicinq of 
satellites. 

PA0 Susan Starnes (KPRC) Television. 

STARNES This is for Bruce and Bob. Yesterday, we heard 

some comments that you seemed cold in particular inside the space 
suit when President Reagan called. Could you comment on the 
comfort of the working conditions inside that space suit 
yesterday? 

SPACECRAFT Of course, I'd be glad to Susan. One thing that 
you have to bear in mind is the actual physical workload 
associated with flying the MMU is very low. My medibolic rate 
was very low. We were going through some engineering evaluations 
which by their very nature were intended to be slow and 
deliberate maneuvers where we put in a little impulse and watch 
wnai. happens to the maneuvering unit, and I was hanging out over 
the edge of the payload bay for quite some period of time with 
all of my lower torso exposed to radiation to space, and t aid 
get quite chilly during that period of time, but it certainly was 
nothing that was unendurable. 

STARNES So you don't think that this would be a problem for 

future people working out in space on satellites. 

SPACECRAFT No Susan, but by the same token, I was working at 
a rather high metobolic rate inside the bay on the hydrazine 
transfer stuff, and I was quite warm and comfortable at the same 
time . 

p AO Silvon Rodrequez. 

At the veiy least, you could wear long underware. 

For Vance Brand, there have been a few 
disappointments like the IRT and the wrist not working 
properly. What would you characterize, speaking for the crew, as 
being the major disappointment so far. 

SPACECRAFT The major disappointment is the fact that, 
although they were deployed okay, the satellites didn't get into 
orbit. That's - - that was what I call an extreme 
disappointment. Next to that, I guess the IRT and the RMS wrist 
sort of ranked together. However, I think, although these were 
latter to things for disappointments, we accomplished what was 
needed to be accomplished to start the next mission into motion 



STS-41-B AIR/GROUND TRANSCRIPT t413j 041;12:01 2/10/84 PAGE 2 

in satellite repair, we could have done some other things, but 
they - - you could say they would have been frosting on the cake. 

PAO John Petty (Houston Post) . 

PETTY For Ron McNair. Can you give us an update on the 

rats. Are you seeing any difference in the behavior of the 
arthritic rats than you might expect on Earth? 

McNAIR As a matter of fact, I've seen some pretty dramatic 

differences, I had the opportunity to observe a similar 
experiment on the ground for a couple of weeks, and I would say 
that the rats that we had here on orbit are probably much much 
better off than ground controlled. I have seen very little 
detectable migration of the (garble) to compare from the PAW, 
that was affected with the arthritis to the opposite paw. 
There* s been very little migration, as opposed to what you see on 
the ground with similar situations, so I'd say that experiment is 
showing some promise, and it will further about will have to 
await further announcemens before any conclusion can be made. In 
fact, you can't really make any conclusion based upon this very 
limited experiment with only 6 flown animals, and several ground 
controlled, but it would take a much larger scale experiment to 
come up with any conclusive results and I think from here we'll 
go on and (garble) experiments and perhaps come up with some 
useful data and information. 

PAO Dave Jackson (Time Magazine) 

JACKSON To Bruce McCandless and Bob Stewart, again. I've 

always been curious how someone's expected to have an adventure 
up in space like you guys enjoyed, and then fall asleep a couple 
of hours later. Did you having any trouble getting to sleep and 
what do you dream about after you have a real life adventure like 
that? 

SPACECRAFT No, I haven't had any trouble sleeping up here. 
Basically, at night, we darken ship, turn out the lights, rig the 
sleeping bags, have a nice dinner, and sack out. The overall, if 
I could call it routine or protocol for an EVA, turns out to be - 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t414j 041:12:06 2/10/84 PAGE 1 



SPACECRAFT ...and sack out. The overall, if I could call it 
routine or protocol for an EVA, turns out to be fairly physically 
demanding starting with the preparations a couple of hours ahead 
of time and getting into the suits and getting the airlock 
depressed, and various other things. So that even though I 
mentioned the metabolic rate while actually flying the MMUs was 
quite low. After a 6- hour EVA which, is about what ours turned 
out to be, you are tired and you fall asleep quite 
satisfactorily. And as far as dreaming about things, I very 
rarely have dreams so I don't have anything to comment on. I 
just sacked out and work up the next morning. 

PA0 Carlos Byars, Houston Chronicle. 

BYARS For Bruce and Bob. The, I was wondering how well 

the MMU handled compared to the many simulations that you've been 
through. Was it easy as you expected? It seemed to be extremely 
smooth, but how did it compare with the many simulations you've 
been through? 

SPACECRAFT Well, Carlos, I would say the dynamics are very 
similar to the SOS in Denver. I think it does an excellent job 
of duplicating the orbital mechanics, the very sense of the 
dynamics of the MMU itself. The one thing that — two things 
that I did notice about it is, that are not modeled on the 
simulator, are, well, when you're maneuvering in translation with 
the attitude hold on, the machine has a mode when it conserves 
fuel by turning jets off, so you can get a jet shattering effect 
that is not modeled on the simulator. That surprised us at first 
until we found out exactly what was happening. And the second 
effect is that at the simulator in Denver you can hear several 
motors and feel several motors turning, where you couldn't up 
here, it was just extremely smooth. 

PAO Craig Covault, Aviation Week. 

SPACECRAFT I agree 100 percent with Bob there. The other 
thing that had been a big question is whether we would be able to 
tell when the thrusters were firing or not, since tests in the 
thermal vacuum chamber in Houston indicated that the noise in the 
suit was sufficient to mask the thruster firing noise. I found 
that I could sometimes hear what I figured was gas flowing, but I 
could certainly tell when the thrusters were firing and that the 
suit actually was a lot quieter in operation here at 12.3 psi and 
m vacuum than it was previously. So with those comments, I 
think the simulations that we'd gone through were quite 
representative and gave us excellent training to fly the mission. 

PAO Craig Covault Aviation Week. 

COVAULT For Vance and Bruce. The maneuver to pick up the 

foot restraint was a pretty interesting thing to watch and I know 



STS-41-B AIR/GROUND TRANSCRIPT t414j 041:12:06 2/10/84 PAGE 2 



you had considered that type of activity as somewhat of a rescue 
mode, could you take a minute and discuss what you went through 
to go retrieve the restraint? 

SPACECRAFT Well, after we saw it floating very slowly up out 
of the bay, we thought about it for a minute, wondering whether 
we ought to let it go or go after it and decided that after 
quickly checking with Houston and telling them what we were up 
to, that — we had all the capability to go after it, so why not. 
We just had to set a couple or three switches and move a 
translation control handle on the left and actually look at it 
and approach it, like you would flying a lot of other types of 
vehicles. And when we saw it coming back our way into the bay, 
why,- we just let it slowly drift into the bay. Bruce immediately 
saw what was going on and headed over to — well he actually 
scrambled down the side of the bay toward it and he got to the 
end of a wire that was a safety wire and couldn't go any further 
so he just waited for it to drift into his hands. And basically, 
it came as a complete surprise but we sort of think it was a 
blessing because we, we always have to be ready to rescue a 
crewman, for example, should a tether break, which is unlikely, 
of course, or a backpack go out of control. That is our, always 
our ace in the hole, and it was shown that that could be done. 

PAO Susan Reed, Cable Network News. 

REED This is also for Bruce McCandless and Bob Stewart. 

Putting your spacewalk in an historic perspective, do you think 
that history. 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t415j 041:12:11 2/10/84 PAGE 1 



PAO Susan Reed, Cable Network News. 

REEr) This is also for Bruce McCandless and Bob 

Stewart. Putting your space walk in an historic perspective, do 
you think that history will consider it as significant as the 
Wright brother's first flight? 

SPACECRAFT No. I don't think it's as significant as the 
Wright brother's first flight. What we've been doing is just 
incrementally advancing the state of our capabilities in 
extravehicular activities, or spacewalks. This one was a 
significant increment, but I don't put it in the same category as 
man's first flight in an airplane. And I would, at the same 
time, point out to you the fact that although Bob and I and the 
rest of the crew have been highly visible during all this 
operation, there are literally thousands of other people down on 
the ground that have put a lot of effort into developing the 
Orbiter and the pressure suits themselves, which worked 
flawlessly in the maneuvering units, and all of the other pieces 
of hardware, Susan. 



PAO Roy Neal, NBC News. 

NEAL Okay, here's one for Hoot Gibson, and for, I guess 

you, Bruce, or Bob. Because we're told those communication 
satellites, Westar and PALAPA are in low Earth orbit, and because 
they are apparently healthy, would you discuss for us the 
feasibility on a future flight of going out to pick them up and 
rescue them, especially in view of the save from yesterday. 

SPACECRAFT Well Roy, we don't have a real good feeling for 
that right at this time, but it would appear that with the type 
of orbit that they're in, about a 150 mile by 600 mile orbit, 
wejd have a very difficult time getting to them. So I don't 
think that we hold a whole lot of hope for them at this point. 

NEAL If you could get to them though, Bruce or Bob, how 

would you feel aoout trying to pull something like that in, 
something that doesn't have any grapple? 

SPACECRAFT The face that it doesn't have a grapple fixture, is 
not in itself a problem because as you saw on both of our EVA's, 
with a device such as the trunnion pin attachment device, 
affectionately known as the TPAD. We can attach a grapple 
fixture to just about anything using the maneuvering unit. More 
permittable is the fact that these satellites were, and I presume 
still are, rotating at approximtely 50 rpm. They're spin 
stabilized satellites so that we would have to develop a 
technique for attaching to them, and I'm not sure that 50 rpm is 
within the capability right now of the maneuvering unit to match 
rates and attach a grapple fixture. That's a little bit 
speedy. The other thing is that we would then need some sort of 



STS-41-B AIR/GROUND TRANSCRIPT t415j 041:12:11 2/10/84 PAGE 2 



special cradle or support equipment in the payload bay so we 
could bring them back to Earth. I think when you add all this 
up, you would say that it was technically feasible, although 
difficult, and of course, difficult translates into expensive, so 
that it probably isn't something we're going to go do. 

PAO CHRIS PETERSON, KTRH Radio. 

PETERSON For Vance Brand. Vance, you've sounded like you've 

really been enjoying yourself up there. Are you going to get 
back in the back of the line and get in line for another flight 
when this is all over? 

SPACECRAFT Well, that's really up to NASA management, but I'd 
really like to. I can't tell you how great it is up here. I 
think a lot of you would really enjoy it. We sure do. 

PAO LYNN SHERR (ABC News) 

SPACECRAFT Hey, Vance isn't the only one that's enjoying 
himself up here. 

SCHEAR This is for Bruce and Bob. Gentlemen, when you 

were on the MMU's, you were variously described on Earth as being 
human satellites, as being Buck Rogers people. Can you tell us 

how you thought of yourself while you were out there? 

SPACECRAFT Well, I thought of myself as an engineering test 
pilot evaluating a very high and fast flying machine of a quite 
unusual design. 

SPACECRAFT But in the cabin here, they call each other Flash 
Gordon and Buck Rogers. 

PA0 Craig Covault, Aviation Week. 

COVAULT Another one for Bruce and Bob. One of the 

questions we had before you flew was whether or not spending some 
time in zero g before going out and flying MMU's would bias your 
ability to tell how fast you were going. Did you notice any 
change? J 

SPACECRAFT No, Craig. I didn't notice any change. You've got 
to bear in mind, of course, that what we were using as our 
reference was the Orbiter - - 



END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t416j 041:12:16 2/10/84 PAGE 1 



COVAULT ...before going out and flying MMU's would bias 

your ability to tell how fast you were going, did you notice anv 
change? J 

SPACECRAFT No, Craig, I didn't notice any change. You've got 
to bear in mind, of course, what we were using as our reference 
was the Orbiter and concentrating on landmarks on the Orbiter and 
things of that sort to judge our relative motion. I guess I 
would have to say though that I think that, apart from the zero- 
g, spending a day or so up here and getting used to the fact that 
you can see the Earth going by at great speed and random 
attitudes before setting out into the maneuvering unit certainly 
made me feel a lot more comfortable while I was flying around out 
there. And that's a visible effect that we have not reproduced 
on any of our simulators. 

PAO Mark Kramer, CBS News. 

KRAMER For Vance Brand. There's been a lot of coverage 

down here on earth talking about a trouble-plagued mission, and 
I wonder if the dif f iculities you've faced with the satellie 
failures, the IRT, and yesterday the arm, have led to a pall on 
the part of the crew. Have you had to fight off a depression 
from these diff iculities, or have you carried on without that 
hanging over your head. 

SPACECRAFT Well, of course, up here we, we don't know what is 
m the papers and what is being said so I guess we find that out 
when we get back. I must say the first couple of days, we were 
thinking of a satellite deployments, we were very disappointed to 
hear that the satellites didn't get into high orbit and somewhat 
surprised because everything appeared to have gone perfectly 
through the whole operation, from our viewpoint. The — we did 
get into other things immediately, the rendezvous. I think we 
didn't get everything done we wanted to but we, we really were 
pleased the way the equipment worked, the radar and the sensors 
we have that we used, like the star tracker. Finally, really the 
E Y*'?' 1 think we've been on top of the world, since they came 
off because those were very exciting things to pull off up here. 
I think we feel threr's been some adversity but a lot has been 
accomplished. 

PA0 Susan Starnes, KPRC Television. 

STARNES Past crews have reported sights they felt were 

amazing or shocking looking back at the planet. For the flight 
crew, could one of you or all of you describe anything that you 
have seen, that you felt was shocking about the planet, perhaps 
amazing or strange? 

SPACECRAFT We're all shaking our heads and trying to see if we 
can think of anything that we've seen that was strange or 



STS-41-B AIR/GROUND TRANSCRIPT t416j 041:12:16 2/10/84 PAGE 2 



shocking and none of us are, I don't think, coming up with 
anything that was like that, I think the one impression that we 
do get is just how much beauty the Earth does have. Looking at 
the oceans and the cloud patterns and the continent and, as Bruce 
and Bob have referred to, the magnificant view that you get from 
up here. I guess that's probably been the most striking thinq 
that we've seen. 

PAO Jules Bergman ABC News. 

BERGMAN This is for Bruce and Bob and then Vance and, 

that's not legal John? 

PAO Two . 

BERGMAN You two have the only time in the MMU. How anxious 

are you to go up and fly it again and do you feel NASA should put 
you ahead of the next crew since you're experienced in flying it? 

SPACECRAFT Well, of course, that's a, a call for NASA 
management to make; however, perhaps in a self-defeating mode, 
let me say that we have endeavored in the development of the MMU, 
myself and Ed Whitsett in crew systems division and others, to

RODRIGUEZ This is also for Flash and Buck. The MMU at the 

beginning I think there was a little rattling described down here 
on Earth, can you provide us with a little more detail on that 
and did anything at all go wrong with the MMU, a thruster 
sticking, or any problems at all.

RODRIGUES The MMU, at the beginning I think there was a 

little rattling described down here on Earth. Can you provide us 
with a little more detail on that, and did anything at all go 
wrong with the MMU, a thruster sticking, or any problems at all? 

SPACECRAFT With regard to the rattling, when you translate 
you've put four thrusters, and since the center of gravity of the 
unit varies depending on the weight of the person, his size, and 
whether you have something like the trunnion attachment device 
hung the front or not, in order to keep your attitude pointed in 
the right direction, the system automatically turns appropriate 
thrusters off for 40 ot 50 milliseconds, and then back on. It 
does this on the simulators also, but the cue lights stay on 
constantly since there are some thrusters on, at least at all 
times, and the response of the simulator is slow enough so we 
have not put that in. Basically, it was just a little bit of a 
surprise that we felt this rattling as the system performed its 
intended job of saving propellant, and holding attitude. The 
second part of your question, no we really haven't found anything 
on the MMU's that was performing of f -nominally , and we've had no 
rears . 



PAO John Getter (KHOU Television) 

GETTER Along the lines of what Hoot addressed earlier. 

Those who have come before you have come back and said they 
gained unique insights. Dick Truly said he was struck by the 
fact there were no borders visible from space. Paul Weitz came 
back and said that he was struck by how small the Earth is and 
that we had better do something about the environment. For 
anyone who would care to address it, have any of you from your 
unique perspective gained any new insights that you perhaps did 
not expect. ^ 



SPACECRAFT I guess one reason they were kind of hesitant to 
answer that question is that we've benefitted from the 
experiences and the debriefings of all the crews that have flown 
before us, and trying to report on a new significant insight that 
these guys haven't seen and reported and we were expecting is 
quite challenge. 

SPACECRAFT I think - I've had a chance to be up here before, 
and I think it's - each time is just like the first time, 
almost. I'm so amazed at how the world is put together. It's - 
you know we talk about overcrowding, yet we crossed vast oceans 
and deserts and mountain areas (garble), the largest cities 
looked like very small areas on a continent, and it really puts 
me to thinking that our problems on Earth aren't that we're short 
of land, it's that we're short of water to make things grow in 
the deserts, and we're short of electrical power to pump the 
water uphill perhaps, and to (garble) water. If we had unlimited 
electric power and a lot more technical capability. We've got a 



STS-41-B AIR/GROUND TRANSCRIPT t417j 041:12:21 2/10/84 PAGE 2 



lot of land on Earth that presently is unusable, which we can see 
from our windows here in the spacecraft, that would really help 
mankind. I don't know how you get this technoloy, but unlimited 
electric power would make it possible for several times the 
population of the Earth to exist on the Earth. 

PA0 Sounds like we have less than 30 sec. Olive 

Talley, UPI, 

TALLEY Well, I hate to end it on this note, but Hoot or 

anyone else, how troublesome have the toilet problems been during 
the flight, and would you recommend any design changes in that 
piece of equipment? 

SPACECRAFT We have had, I guess what we'd have to characterize 
as perhaps a minor problem with the WCS or Waste Control 
System. It's presently operating very nicely and it's the sort 
of thing that I guess it takes a little bit of attention to keep 
up with it and keep the thing operating properly. I think it 
could bear a couple of changes that would make it a whole lot 
more reliable and a lot more long lasting, but it has served us 
relatively well, I'd have to say. 

PA0 We'll take one last question. Roy Neal, NBC 

NEAL All right. Ron McNair, we haven't heard very - - 

END OF TAPE 



STS-41-B AIR/GROUND TRANSCRIPT t418j 041:12:25 2/10/84 PAGE 1 



NEIL All right, Ron McNair, we haven't heard very much 

from you and I wonder if perhaps you could give us your 
evaluation of this mission? I'm looking at the fact that you are 
a scientist, you've been there and, of course, I'm not looking 
for the application to solar max, we've already heard that, but I 
mean the overall applications as you see it to this mission? 

SPACECRAFT Okay, the, of course I too, I was envolved with the 
PAM deploy and was very shocked and surprised that they did not 
function properly. That was a disappointment at the beginning, 
however, as the mission progressed, we had a great deal of 
success in the areas of experiments, we have a number of 
experiments on this mission that have sort of taken a back seat 
to the more photogenic and media catching events such as the 
MMU's and so forth but the experiments have gone very well with 
lots of promise for the future in applications. We've also flown 
the SPAS 01 satellite which has a lot of experiments, they have 
gone very well, and the EVA's were a great success as I was 
personally envolved with the first checkout of the manipulator 
foot restraint in which we drove Bruce around in the work station 
which will also be applied to the solar max mission. That proved 
to be a very, very well designed, well thought out piece of 
hardware, it's going to be very useful to us and it was fun 
testing it and maneuvering it around the bay. In general, my 
perspective as are other crewmen is that we've had a really 
useful, we've had a really productive mission in spite of the 
failures and minor setbacks that we have undergone. All in all 
we've accomplished some good science, we accomplished that, we 
demonstrated the solar max mission is a viable endevear and we 
think that our main objectives were accomplished allowing the 
fact that though we had a good deploy, the satellites did not 
reach orbit, but all in all we had a good mission, we think. 

PA ° Crew aboard the Challenger, thank you. Ladies and 

gentlemen of the press, thank you, we're ajourned.

downlink and we're just standing by whenever you can get started 
with the unberthing of the SPAS. 

SPACECRAFT Okay, John, I'm just upstairs getting ready to 
start throwing some of the switches on that and the expression 
unberth the SPAS is probably not what you mean to say, is it?

8 minutes mission elapsed time. Information for those of you in 
the Houston area about the visibility of the Orbiter as it 
crosses over. We expect that the Challenger will be visible in 
the Houston area beginning at approximately 5:58 am central 
time. The azimuth on that is 260 degrees. During its pass over 
the Houston area we'll achieve a maximum elevation of 21 degrees 
with the azimuth about 170 and should be going out of sight 
almost due east at approximately 6:05 am. Just to repeat that 
now in case you didn't get it, it'll first become visible at 
about 5:58 coming out at about 260 degrees. It will achieve the 
high point in the sky that crosses over the Houston area of about 
21 degrees with the azimuth about 170 degrees and it will 
disappear over the eastern horizon almost in a due easterly 
direction at approximately 6:05. We'are standing by for the

CAPCOM Okay, Bruce, first one is, be advised we're going 

to TMBU the H20 align temp parameter that we - continues to 
trigger the caution and warning messages on us. We'll be 
watciing it on the ground, it appears the heater's working fine, 
it just happens to be controlling to the wrong temperature 
band. Second item, on panel Rl, we'd like to take cryo 02, tank 
2, heater alpha to off, reason for this we're seeing a divergence 
between tanks 1 and 2, in quantity, approximately 3 1/2 hours 
from now we'll give you a call back to turn that back on. 

SPACECRAFT Okay, it's off, and we'll turn it back on, on your 
call. We've inhibited the pressure caution and warning parameter 
so we can talk to you this pass and we're proceeding into the 
manual cabin pressure regulations.

CAPCOM And Challenger, if you're ready to copy we have a 

S-band test we'd like you to perform, if we don't acquire you 
within 10 minutes on TDRS. 



SPACECRAFT Okay, stand by just a second, Jerry. Okay, Jerry, 
go ahead. 1 ' 

CAPCOM Okay, guys, if we don't acquire you within the 1st 

10 minutes of the TDRS pass this time, we would like you to go on 
C3, the S-band PM rotary, select each of the positions, pause for 
at least 2 seconds, and at the conclusion of that go back to 
GPC. We're trying to get some engineering data to help us post 
flight. 



SPACECRAFT Okay, understand, if you do not acquire us by 10 
minutes after predicted TDRS AOS we should cycle the S-band PM 
rotary switch through each of the 8 positions, pausing for 2 
seconds. Do you want us to work for signal strength at each 
position also? 



CAPCOM That's not required, Bruce, if you'd like to, just 

for your own information, it could help us also. 

SPACECRAFT Okay, at the end of that back to GPC what if we 
still haven't required you? 

CAPCOM We'll I imagine just like in the past, we'll 

finally acquire you sometime in the pass. 

CAPCOM As we cycle through these 8 positions, are you 

going to try to grab us when you see signal strength or 
something? 



CAPCOM That's a negative, Bruce, we won't, this is more 

just an engineering evaluation right now.

AOSlock, I've got (garble) 7 1/2 minutes from AOS right now. 

CAPCOM Roger, 03:35:29 predicted AOS TDRS. Challenger, 

Houston, 30 seconds LOS Hawaii, TDRS at 03:35. 

SPACECRAFT Okay, Houston. Houston, this is Challenger on S- 
band over. 



CAPCOM 



Roger, Bruce, loud and clear. 



SPACECRAFT Okay, Jerry, we didn't get you at 3 (garble) so I 
started to sweep, I'm now on lower right forward, which has the 
highest signal strength, so I can read the numbers off to you, 
and then go back to GPC or whatever you wish. 

CAPCOM Okay, we'd just like you to go back to GPC, Bruce, 

thank you. 

SPACECRAFT Okay, lower right forward is the magic one riqht 
now. 3 



CAPCOM

switch selecting the various antenna's to see which works in v:hat 
manner. The INCO, the communication officer here in the Control 
center, wanting to get some data on what the various readings are 
from those antennas. The TDRS acquisition lately has not been 
quite up to par. And they're checking out all the various

PAO - - what the various readings are from those 

antennas. The TDRS acquisition lately has not been quite up to 
par and they're checking out all the various Orbiter antennas to 
see what the performance is on each of those. 

CAPCOM Challenger, Houston. Got a couple notes for you. 

SPACECRAFT Roger, Jerry. Go ahead. 

CAPCOM Okay, Vance. First one we'd like to go over on 

panel LI, take the rad controller outlet temp to normal and then 
cycle the flash evaporator control primary alpha off then back to 
on. 

SPACECRAFT Okay, that's complete. 

CAPCOM Okay, second item. We would like to send you 

several teleprinter messages at Hawaii, next pass, at 05:01 
approximate so if you can have it configured for us. 

SPACECRAFT Okay, Jerry. 

CAPCOM And the third item, tell Ron that will be prepared 

on the next TDRS pass to take some live TV if you'd like to ship 
some to us. 

SPACECRAFT Sorry, Jerry, would you repeat that, please. 

CAPCOM Okay. For Ron, if he would like to send us some 

live TV the next TDRS pass we would be glad to get it from him. 

SPACECRAFT Okay. Anything in particular you're most 
interested in or just let him, let us select. 

CAPCOM We'll let the selections be Ron's choices. 

SPACECRAFT Okay, very good. Jerry, once again, where would 
you like to see that TV again? 

CAPCOM Okay, Vance, it'll be next rev, the first portion 

of TDRS while we can have high gain and this is per Ron and my 
discussions premission on what he would like to show us. 

SPACECRAFT Houston, Challenger. 

CAPCOM Go ahead, Vance. 

SPACECRAFT Roger. We are in the middle of packing up here. 
We could send some stuff down to you and, but we might make it 
fairly short and Ron's had other discussions since those he had 
with you so he might be sending you some different stuff. 



STS-41-B AIR/GROUND TRANSCRIPT t426j 041:16:49 2/10/34 PAGE 2 

CAPCOM Okay, there's no need to send us anything. We just 

thought that he might want to send us something. Otherwise, he 
can disregard. 

SPACECRAFT Okay, thanks. 

SPACECRAFT Houston, Challenger. 

CAPCOM Go ahead, Vance. 

SPACECRAFT Okay, since we're not too far from presleep and 
pretty busy packing up, why, we won't send you anything down at 
ai; then. We're going to put the VTR to bed. 

CAPCOM Roger, we concur on that and let us know when the 

r.eior\. : riti-r's configured. 

AC£C;<AFT Okay. How about sending a test now. Bruc* lust 
c it configured. 

CAPCOM Vance, I guess we're not going to be able to do it 

u.itil we gut to Hawaii so hopefully it'll work. 

'ACKORAFT Okay. We'll be watching for it. 

CAPCOM Challenger, Houston. We're 7 minutes till LOS

to send you and I've got several notes also. 

SPACECRAFT Okay, stand by 1. Go ahead, Houston. 

CAPCOM Okay Vance, several presleep activity notes for 

you. The first one, Rl 02 tank 2, heater alpha to auto. 

SPACECRAFT Okay, I'll go over and get it. Okay, 02 tank 2, 
heater alpha to bravo, I mean alpha on, to auto. 

CAPCOM Roger that, Vance, second item, we would like to 

change the A DAP to alpha 6 and the normal deadband we'd like 
sent to 10 degrees. 

SPACECRAFT Okay, I got it. 

CAPCOM Further, we'd like to turn manifold L3 R3 drivers 

off, and on 016, RJDA, to barvo, L3R3 manifold driver to off. 

SPACECRAFT Okay. 

CAPCOM Further on that activity, also we'd like to 

override the left and right manifold 3 status to close on spec 
23. We'd like to do these activities after the IMU align. 



STS-41-B AIR/GROUND TRANSCRIPT t427j 041:17:21 2/10/84 PAGE 2 
SPACECRAFT Okay. 

CAPCOM Okay, IMU align is meant to - intend to include 

also the COAS work. We'd like a status on the GAS activities 
today, times of doing those, and also I've got a vernier hotfire 
test if you're ready to copy? 

SPACECRAFT Okay, go ahead. 

CAPCOM Okay, Vance, as last evening, the last thing prior 

to sleep, we'd like to do DAP A manual vern, DAP rotations excel, 
excel, excel, and the RHC + pitch for 10 seconds, as opposed to 5 
last night, and after you've performed that, we'd like to 
reconfigure DAP, A auto norm, rotations discrete. 

SPACECRAFT Okay, Jerry, let me get some of this back to you. 
On auto 1, I got the heater, called that to you. You'd like soon 
the DAP to A6 10%, incidentally, when did you want that again? 

CAPCOM Okay, we can reconfigure the DAP and do the 

manifold work after you've done the IMU and COAS work and that 
was 10 degrees normal deadband. 

SPACECRAFT 10 degrees deadband, so everything that follows is 
after the final COAS thing. 

CAPCOM That's affirm. 

SPACECRAFT Okay, you'd like RJDA 2 to bravo - -

activities for today now. 

CAPCOM Okay, ready to copy. 

SPACECRAFT Okay, Jerry, we got group golf 4+54, and that was 
the only GAS activity for today, 4+54 for group golf. 

CAPCOM Okay, copy that, thank you, Ron. 

SPACECRAFT And Jerry another development, we managed to get 
the VTR to work for us a bit. it was able to do some 
L^ttnc! 6 ^ still unwilling to try any of our flight tapes 
on it because it's still in somewhat of an uncertain condition. 
However, I did manage to get some recording of the AEM state. I 
did not have to go to 16 millimeter, but I got it on tape, I took 
a fresh tape and put it in, so just wanted to alert you - inform 

£h^°L ** tm hl l°L *: nin 9 s aboufc a week ago, we were unable to do 
what we discussed before I left, thanks.

SPACECRAFT Jerry, just did an IMU align did you copy the 
numbers? 

CAPCOM Roger, Vance, it looks to us like we may have not 
seen the torquing of the IMUs. 

SPACECRAFT Okay, might have miskeyed it. Okay, Jerry, just as 

I was about to hit item 16 execute, we got a RM fail IMU 1. I 

guess, with your permission, I'll hit the execute and we'll align 

CAPCOM Okay, stand by, Vance. Okay, Vance, we concur with 

that, go ahead and align all three, do not reselect 1. 

CAPCOM Challenger, Houston, after a comm drop. 

SPACECRAFT Roger, we have you now. 

CAPCOM Okay, Vance, did you copy you're go to align all 

three, but do not reselect number one? 

SPACECRAFT Okay, and did you, if you observed that one, I 
don't guess you need the data, huh? 

CAPCOM That's negative, Vance, we'd like you to go ahead 

and read us the data anyhow. 

SPACECRAFT Okay, okay, stars 31 and 12, angular error .02. 
Delta X going across -.07, -.03, -.10. Delta Y, +.05, -.14, 
+.09. Delta Z, -.12, -.09, +.06. Torqued at 7 days, 5 hours, 52 
minutes, and the reason you didn't see the item 16, or the 
alignment on the first attempt was that the alignment was 
performing with no astrisk after item 10, 11, and 12. They must 
hava been taken away when we went to OPS 8 and back today. And 
we we're so use to having them there, we missed them. 

CAPCOM Okay, Vance, copy all of that, we currently do not 

see anything wrong with IMU 1, however, we want to look at some

tlight controllers here in Mission Control will look at the data 
on that one and then advise the crew. They do not see anything 
wrong with that IMU. Flight Director Harold Draughon has said 
that he may put the crew to bed about an hour early today, so 
that would be about an hour from now. They are already in their 
scheduled presleep period and buttoning things down for the 
night, getting ready for tomorrow's entry. So we may be trying 
to put the crew to bed in about an hour from now. Things are 
otherwise very quiet here in Mission Control and we have about 4 
minutes remaining in this pass through the tracking data relay

H20 pump loop 1 to off, please. That's to make sure we don't get 
any alarms during the night on GPC cycles. We had an indication 

^hf^^^ y ° ur high PP02 alarm was Partially at least caused by

SPACECRAFT Okay, loop 1 water pump is off, and advise we've 
completed the star aline and then the COAS, you knew about the 
star alme but then the COAS cal, COAS cal went I think very 
well The first one was a - mark was a fluck, so I took 7, the 
last 6 were fairly consistent, and I can give you the numbers if 
you'd like.

others were 0.20, 0.10, 0.10, 0.10, 0.10, 0.12. 

C ^ P, T? M , Copy those ' Vance. And we're going to get the dump 

of the data around the time of your IMU RM fail and hopefully 
we'll have an answer for you by early TDRS.

SPACECRAFT I was just joking when we were talking about Buck 
Rogers and Flash Gordon, but I think it's too late, probably the 
names have stuck. 

CAPCOM it is too late, you're correct, Vance. 

lt° nn Mission Control Houston, we're losing contact with 

the Challenger through the Hawaii station. Be picking up again 
in about 7 minutes through the tracking data relay satellite. 
Little note there, post script from Commander Brand, as he went 
over the hill from Hawaii indicating that his nicknames applied 
to McCandless and Stewart about Flash, being Flash Gordon and 
Buck Rogers, just intended in jest, but apparently he said the 
names have stuck, so they may be known as that around the 
astronaut office for a while. Things are very quiet here at 
Mission Control, all the system officers have pretty well squared

the Orbiter systems for the night. The crew officially according 
to the timeline have about an hour and 15 minutes remaining in 
their day before they are put to bed for the night, but Flight 
Director Harold Draughon has indicated that he would like to get 
them to bed an hour early, give them plenty of sleep before the 
entry tomorrow. No Orbiter system problems being worked at the 
present time. We did get an IMU fault indication earlier, when 
the crew was doing an alignment that appears to have been some 
sort procedural step that may have been left out there, and they 
are going to back and look at the data on that, but the don't 
believe, don't see anything wrong with that IMU. And this is 
Mission Control at 7 days 6 hours 49 minutse, we have acquisition

CAPCOM Okay, Vance, if you can give us a GNC spec 1 for 

some variable parameter changes, I got a couple notes for you and 
then hopefully we can sign off for the evening. 

SPACECRAFT Okay, GNC spec 1. Ready to copy. 

CAPCOM Okay, Vance, first of all you are go to reselect 

your IMU number 1, we've looked at the data and we think all the 
problems associated with doing the alignment without having IMU 
selected. Another item, state vector that you have on board now 
is good through rev 122, be about another 2 hours before we 
uplink to one that will carry you through the rest of the 
night. We watched the temperatures on your jets after your 
hotfire. They look good they will carry you through the 
evening. And you DAP and jet configurations looks good to us 
also. 



SPACECRAFT Okay, very good. (Garble) we select MU1. 
CAPCOM Roger that. 

CAPCOM Challenger, Houston, you got our spec 1 before we 

could get finished, we'll have to have one back. 

SPACECRAFT Okay, we'll give you spec 1. 

CAPCOM Challenger, Houston, we're done with the spec 1, we 

don t anticipate any further calls up to you, we'll be standing 
by for any messages that you want to give us. Have a good 
evening and see you tomorrow. 

SPACECRAFT Okay, I guess we don't have anything to send up to 
you, so righto, see you in the morning, thank you. 

CAPCOM Roger that, have a good night's sleep. 

SPACECRAFT Will. 



PA0 , Th i s is Mission Control Houston, at 7 days 7 hours 

7 minutes, mission elasped time. We may have had the final 
communication with the crew for the night Fight Director Harold 
Draughon asked around the room if anybody had anything else, and 
nobody had any other things to relay up to the crew. Commander 
Vance Brand said he had nothing additional to talk with the 
ground about, so they said their goodnights, and we may not be 
hearing from them again, unless there is some item that comes up 
that requires their attention. We're actually putting them to 
bed almost an hour early tonight, to allow them plenty of time to 



STS-4I-B AIR/GROUND TRANSCRIPTS t433j 041:19:55 2/10/84 PAGE 2 

get good rest, before tomorrow's entry. Little earlier Vance 
Brand, made a comment about the nicknames that he had applied to 
the EVA crewman, Boh Stewart and Bruce McCandless, we ask for 
clarification as to which was which. He called one of them Flash 
the other Buck. It appears that he was refering to Bob Stewart 
as Flash and Bruce McCandless as Buck. Challenger is out over 
the continent of South America right now. Right about 60 degrees 
west longitude and at the bottom of the ground track, 28 and a 
half degrees south. Right about in the center of the southern 
third of the continent, and on the last quarter of orbit 118 
And this is Mission Control at 7 days, 7 hours, 10 minutes, 
mission elasped time. We have decided to cancel the next change

Draughon. We had all the entry figures and calculations and the 
necessary data for tomorrows entry at the Gary Coen change of 
shift briefing several hours ago, and the only thing that has 
been going on here in the Control Center with the crew has been 
some cabin stowage items, powering down getaway special 
canisters, and simply getting ready for sleep, and preparing for 
tomorrow's entry. So we see no need to hold this next briefing, 
and have conducted a poll of the news organizations, we don't 
believe it is necessary to have one. So repeating the change of 
shift press conference with off-going Flight Director Harold 
Draughon, originally scheduled for 3:30 pm central time has been 
cancelled. This is Mission Control.

PA0 and preparing for tomorrow's entry, so we so need 

to hold this next briefing, and have conducted a poll of the news 
organization, we don't think that it is necessary to have one. 
So repeating the change of shift press conference with off going 
Flight Director, Harold Draughon, originally scheduled for 3:30 
pm central time has been cancelled. This is Mission Control. 

p AO Mission Control Houston, 7 days 7 hours 16 minutes, 

mission elasped time. Just to repeat our announcement of a few 
minutes ago, a change of shift press conference with off going 
Flight Director, Harold Draughon, originally scheduled for 3:30 
pm central time, has been cancelled. The shift here has been 
very quiet, only cabin stowage and a few other activities have 
been going on since our last briefing this morning, and we have 
already made all the calculations and provided the numbers that 
apply to entry. So we have decided to cancel this change of 
shift press conference. This is Mission Control Houston. 

PA0 Mission Control Houston, the planning team has 

taken over from the orbit 2 team, and we would offer this 
reminder, we have changed and cancelled the Harold Draughon 3:30 
pm change of shift press conference. The next press briefing 
will probably be postlanding unless we hold one tonight at the 
end of the planning shift. We'll let you know about that as we 
get into the evening. At mission elasped time 7 days 7 hours 57 
minutes, this is Mission Control Houston. 

PAO Mission Control Houston, all quiet aboard the 

Challenger and here in Mission Control. The ground 
communications officer reports that on the next TDRS pass, on 
orbit 119, about 2 hours from now, there will be a test involving 
both the Landsat 4 spacecraft and Space Shuttle Challenger. Both 
will be transmitting through the tracking data relay satellite at 
the same time, which will be the first time that 2 orbiting 
spacecrafts have attempted that, to utilize the communication 
satellite that NASA has up there at the same time. And that will 
be coming the TDRS communication through - the Landsat 
communications through TDRS will be coming at mission elasped 
time 7 days, I'm sorry, GMT 41 days, 23 hours, 10 minutes. And 
it will go until GMT 41 days, 23 hours, 25 minutes, or about a 15 
minutes test transmission. At mission elasped time 7 days 8 
hours 14 minutes, this is Mission Control Houston. 

PA0 Mission Control Houston, we're AOS TDRS on rev 118, 

processing a little bit right data. A reminder we have cancelled 
the 3:30 pm press conference with Harold Draughon, at mission 
elasped time 7 days 8 hours 26 minutes, this is Mission Control 
Houston.

orbit 119, 119 orbits of the earth. Thus far in Shuttle mission 
41-B, currently m a 156- by 145- nautical mile orbit. Current 
altitude 152.8 nautical miles. A few numbers for you, if we do 
go for a nominal landing on KSC runway 15 tomorrow morning as is 
now planned, our touchdown time at this point would be 7 days 23 
hours 16 minutes and 6 seconds. The TIG time, well the entry 
interface time, would be 7 days 22 hours 45 minutes and 9

p ^O Mission Control Houston, all very quiet here in the 

Mission Control Center and aboard Orbiter Challenger, with about 
4 hours and 10 minutes left in the crew's sleep period, prior to 
landing days activities. Right now the Orbiter is on rev 121, 
121 over the South Pacific heading towards the coast of South 
America. Some updated landing time numbers, and these differ by 
only a few seconds from what you've heard before and what you'll 
probably hear again, but we'll go ahead anyway. Entry interface, 
according to the lastest numbers provided by FIDO, would be at 7 
days 22 hours 45 minutes and 8 seconds, begin S-band blackout 
would be at 7 days 22 hours 47 minutes 45 seconds, end blackout 
would be at 7 days 23 hours 2 minutes 46 seconds, and touchdown 
would be at 7 days 23 hours 16 minutes and 8 seconds. We also 
have some entry view angles for a few cities along the southern 
periphery of the United States, and there aren't that many good 
sighting opportunities for the Orbiter during its passage into 
Kennedy Space Center runway 15 for a nominal landing tomorrow 
morning. But we'll give you a brief rundown. For the Houston 
area, there's a marginal chance of viewing the Orbiter and that's 
more local weather than anything else. The highest elevation 
that one would see the Orbiter at tomorrow morning if it were 
visible from the Johnson Space Center would be 23 degrees and an 
azimuth of 172.7 degrees or almost due south, and that would be 
darkness, Orbiter sunrise above so if there was anything visible 
it would be briefly at about 23.1 degrees. Other cities across 
the sourthern U.S., Dallas has a poor chance of seeing the 
Orbiter, San Antonio a fair chance, Laredo has a good chance, a 
few others, Galveston, Texas, has a good chance of sighting the 
Orbiter and we will provide these numbers to the news center as 
soon as this is generated and you can get more information on 
these there. But generally speaking, there aren't that many good 
opportunities around the country because the Orbiter is moving so 
fast and the time at which it might be sunlit from one's 
perspective point, from one's viewing point, with S-turns and 
clouds and that sort of thing, is not going to provide as good of 
viewing opportunity as one might see on a pass during an orbit. 
But we'll get those numbers to the news center. Right now we're 
at Mission Elapsed Time 7 days 11 hours 52 minutes and this is 
Mission Control Houston.

in Mission Control and also aboard the Challenger. With about 50 
minutes left in the crew's sleep shift, we're on orbit 123 
passing through the Bermuda tracking station site. Again, we're 
wondering about the necessity of holding the regularly scheduled 
11:30 p.m. Change of Shift press conference with off-going Flight 
Director, Larry Bourgeois. Given the quiet nature of this shift, 
we rather doubt there's a need to hold that and we'd like to ask 
anyone who has opinions to the contrary to call the JSC newsroom 
or the KSC newsroom and we'll try to go ahead and cancel that in 
about a half an hour or so. At mission elapsed time, 7 days, 15

upcoming Change of Shift press conference at 11:30 is your last 
chance to get some numbers and information from a real live 
flight director during Shuttle mission 41-B. And if you do have 
an interest in holding that, please let the JSC newsroom or the 
KSC newsroom know. This is Mission Control, Houston.

director this flight. And if you do wish to have one, all 
members of the news media who would like to have one, please call 
the JSC newsroom or the KSC newsroom. If we don't hear anything,

PA0 This is Mission Control, Houston. 7 days, 17 hr, 

51 min Mission Elapsed Time. Entry team Flight Director Gary 
Coen just concluded a weather briefing at the — latest weather 
reports at the landing sites. We have a go for the forecasted 
landing at Kennedy Space Center. Weather shows winds of 85 
knots, westerly winds at 40,000 ft; at 20,000, winds from the 
southeast at 20 knots; at 10,000 ft, 10 to 15 knot winds. 
There s — the forecasted winds are expected to mix the air 
rather well around the landing facility and that reduced th* 
possibility of fog at that site. There are some isolated showers 
just offshore. There are no thunderstorms in that system. 
Maximum tops are at 9 to 10,000 ft. The weather people at 
Kennedy proposed to observe those storms all night. If they 
remain well offshore and, in fact, even if they do come within 30 
miles of the Shuttle landing facility, we will continue to have a 
go for landing, but they will be watching those — that weather 
formation. Northrup Strip is NO/GO for landing opportunities 
on 8 m£ ? y- Nortnru P has surface winds of 12 knots, gusting to 
20. That's an 8 knot gust and we have a flight rule which 
prohibits landing in circumstances where gusts exceed 5 knots. 
Edwards is good for landing opportunities today. Scattered

little bit early. Are we go for that? 

CAPCOM Roger, you're go for that, Bob. 

^^f R ^ T * nd we would also like to stow the Ku-band antenna 
right after the sunshields come closed if you're agreeable. 

SPACECRAFT Houston, Challenger, John, I didn't copy. Are w^ 
go for the sunshield opening? 

CAPCOM Roger, you are and stand by for the answer for 

Bruce . 

CAPCOM Challenger, Houston. Bruce, from INCO, you're go 

for that Ku antenna stow but give us a call right before you do 
it because we'll get an LOS and then have to reconfigure. 

SPACECRAFT Okay, we'll be ready in just a minute or so. Right 
after the sunshields come open. 



CAPCOM 



Understand, just give us a call, please. 



This is Mission Control, Houston. Mission elapsed 

«iSn 1* YS ' i? ^ UrS ' 47 minutes - It's, of course, necessary to 
open the sunshields on the Payload Assist Modules which embrace 

£mUh<o?£! lll e es J! in ? e the P a y load bav <3oors won't close over the 
sunshields. So they've got to be retracted in order to 
facilitate door closing. Likewise, before you can close the 

«h?£h £L C ?iJ rSe, . yOU have to stow th ~ at Aboard Ku-band antenna 
which was the nature of Bruce McCandless' question. Payload bay 
door closure would nominally begin at 19 hours, 10 minutes which 
is roughly 20 minutes from right now. We are 3 and 1/2 hours 
away from deorbit burn, 3 hours and 56 minutes away from entry 
interface and 4 hours and 27 minutes away from touchdown at 
Kennedy Space Center, Florida. Presently, mission elapsed time, 
7 days, 18 hours, 48 minutes, this is Mission Control, Houston.

SPACECRAFT Okay, John, we copy. Thank you. 

CAPCOM Challenger, Houston, we're going LOS TDRS. See you 

at Yarragadee at 19 plus 04. 

SPACECRAFT Okay John, see you there. 

PA0 This is Mission Control, Houston. Just before we 
went LOS at TDRS, the payloads officer affirmed that the 
sunshields on the Payload Assist Module that had contained PALAPA 
have opened and, of course, it's a unnecessary to open those 
sunshields before we can shut the payload bay doors. Wp're LOS 
presently. We'll acquire voice only through UHF station at 
Yarragadee m 9 and 1/2 minutes. Payload bay door closinq will 
commence during that Yarragadee pass. However, there'll be no 
downlink data so we will have to rely upon the crew's

p AO This is Mission Control, Houston. Just before we 

went LOS at TDRS , the payloads officer affirmed that the 
sunshields on the Payload Assist Module that had contained PALAPA 
have opened. And, of course, it's necessary to open those 
sunshields before we can shut the payload bay doors. We're LOS 
presently. We'll acquire voice only through the UHF station at 
Yarragadee in 9 and 1/2 minutes. Payload bay door closing will 
commence during that Yarragadee pass. However, there'll be no 
downlink data so we will have to rely upon the crew's voice 
verification that the door closure has at least begun. The 
closure should be complete by the Hawaii pass and we'll get some 
data there and be able to determine that the doors have closed. 
And certainly by TDRS AOS, we will have some high fidelity 
information about the nature of the door closure and whether the 
latch mechanisms have securely engaged. At mission elapsed time, 
7 days, 18 hours, 56 minutes, this is Mission Control, Houston. 

CAPCOM Challenger, Houston is with you at Yarragadee for 7 
minutes . 

SPACECRAFT Yes, we got you Houston, we're halfway through 

payload bay door closing here. 

CAPCOM Roger that. Good show, Bruce. 

PA0 This is Mission Control, Houston. We have voice 

only through UHF at Yarragadee and no data so we're going to have 
to rely on the crew's commentary having to do with the payload 
bay door closure and whether we've got the good motors working 
and how the latch mechanisms operate. 

p AO This is Mission Control, Houston, we're going to 

try to get some data through Orroral after we're LOS at 
Yarragadee. There's a very brief AOS period through Orroral for 
less than half a minute. 

CAPCOM Roger, go ahead Vance. 

SPACECRAFT Roger John, we're looking ahead to the IMU align 
verification, alignment and verification. Are you going to give 
us a PAD for that? 

CAPCOM Vance, the data you have is good and we're going 

LOS here at Yarragadee in 40 seconds. See you at Hawaii for a 
one minute pass at 19 plus 33. 

SPACECRAFT Yes, does that mean we do not need an alignment? 

CAPCOM Negative, Vance, that means the attitude data you 

have for the align on FS1-3 in the deorbit prep is good. 



SPACECRAFT Thank you.

PAO This is Mission Control, Houston. We've lost 

signal through Orroral and it's about 2 minutes here before, I'm 
sorry, lost signal through Yarragadee. And it's about 2 minutes 
before we pick up through Orroral and, again, it's a very brief 
pass and maximum elevation is 4 degrees, meaning that the line of 
sight between the earth station and the Orbiter will be just 4 
degrees over the horizon at the highest point, which accounts for 
the brevity of this pass and certainly no assurance of the 
quality of the data or the voice we'll get. But we'll see if we 
can get some data take from it. And take a look at the downlink 
of payload bay door closure and see how that was going. Mission 
elapsed time, 7 days, 19 hours, 13 minutes, this is Mission

PA0 This is Mission Control, Houston. The landing 

condition winds at Kennedy Space Center have been dialed into the 
Shuttle mission simulator here in Houston, and Astronaut Ken 
Mattingly, the commander of the STS-4 mission, has been flying 
simulated entries in that machine to see if the Kennedy winds 
have any current expected affect on the programmed flight 
characteristics of the Orbiter. Findings of that function, if 
they are unique in any regard, will be uplinked to the crew as an 
advisory. Additionally, John Young, chief of the astronaut 
office, is flying Shuttle training aircraft at Kennedy, a 
modified Gulfstream which is configured to duplicate the 
aerodynamic characteristics of the Space Shuttle Orbiter. John 
Young will be flying that Gulfstream into the Shuttle landing 
facility at Kennedy to, again, measure the effects of the winds

PA0 This is Mission Control, Houston. The data gain 

from the Shuttle Mission Simulator Tests and the Shuttle Training 
Aircraft approaches to Kennedy will constitute an advisory that's 
going to be made to the crew in advance of the landing at Kennedy 
Space Center. We're standing now, standing by now for a start of 
the auxilliary power unit onboard Challenger. These are the 
units which provide hydraulic power to the aerodynamic 
surfaces. Mission elapsed time, 7 days, 21 hours, 29 minutes. 
We're 46 minutes away from deorbit ignition. Challenger's in a 
burn attitude now, essentially flying upside down and 
backwards. Backwards because the OMS burn is retrograde or in 
the direction of flight in order to reduce forward velocity. And 
the vehicle is flown upside down during this maneuver in order to 
provide the crew with horizon reference so that they can look out 
the panoramic front view of the Orbiter, see the earth's horizon 
and, although of course they have instruments, it's always of 
additional comfort to air crew to be able to look out the windows 
and see that the horizon is where the instruments say it's 
supposed to be. 45 minutes from deorbit ignition. An hour and 
14 minutes from entry interface and an hour, 45 minutes from

p AO Flight Director Gary Coen said we're going to press 

on ahead with plans to land at Kennedy Space Center. It's 
Mission Elapsed Time, ~ days 21 hours 45 minutes. John Young, 
Chief of the Astronaut Office has been flying the shuttle 
training aircraft into the shuttle landing facility and has 
advised that the clouds and storm formations that were present 
offshore earlier have dissipated. The only concern remains to be 
patchy ground fog in the vicinity of the shuttle landing facility 
moving east to west across the runway in patches. John Young 
advises that he would land under these conditions. Weather 
advises tnat che fog will probably not get thicker than it i? 
presently and that the sunrise at the Kennedy Space Center a.id 
the increasing temperatures expected immediately before landing 
would probably promote the dissipation of that fog. So based on 
John Young* s assessment, based on the weather assessment that the 
fog will probably not worsen, Flight Director Gary Coen has 
determined to press on for a Kennedy landing. Flight directors 
are going around the room presently polling each of the flight 
controllers to get a GO-NO/GO for deorbit burn and has uniformly 
received go votes. We are 29 minutes away from deorbit ignition 
and 1 hour 28 minutes away from expected touchdown at Kennedy 
Space Center Florida. At Mission Elapsed Time 7 days 21 hours 47 
minutes, this is Mission Control Houston. Flight director Gary 
Coen instructed CAPCOM John Blaha to advise the crew of go for 
deorbit burn. Mission Elapsed Time, 7 days 21 hours 48 
minutes .

SPACECRAFT Roger. We understand. 

PAO This is Mission Control at Houston. Everything on 

control center data displays and the Crbiter Challenger continues 
to look good for nominal landing operations and deorbit burns. 
The deorbit burn will occur out of sight of the control center 
here. Ignition will occur in 14 min. The next acquisition will 
be through Yarragadee, but we don r t have data through there, of 
course, we have voice only through UHF channels, so we'll have to 
rely on the crew's assessment and report of that burn. The 
Yarragadee pass will be 6 min in duration. Following Yarragadee, 
we acquire Guam on orbit 128 at Mission Elapsed Time, 7 days, 22 
hr, 30 min. The Guam pass is very brief, only 3 min in duration, 
at a fairly low elevation of 3.4 deg over the horizon. Get a 
long pass to Hawaii oeginning at Mission Elapsed Time, 7 days, 22 
hr, 42 min. Acquisition for 4-1/2 min through the Hawaii 
station, then entry interface where the Orbiter encounters a 
sensible atmosphere, occurs at 7 days, 22 hr, 45 min. S-band 
blackout begins 7 days, 22 hr, 47 min. It will be about 15 min 
long, when, of course, we aren't able to acquire voice or data 
due to the ionization that builds up around the spacecraft as it 
accelerates through the atmosphere and is encompassed in a very 
thick plasma environment that prohibits radiation of telemetry or 
voice. The Orbiter, again, as a reminder, will be visible in the 
Houston area here at 5:58 a.m., at a maximum elevation of 23 deg 
over the southern horizon moving west to east. Orbiter will be 
at an altitude of 195,000 ft, traveling at Mach 16 during that 
period. We'll exit ... 



CAPCOM Challenger, Houston. We're going LOS TDRS in about 

2 min. Configure LOS. We'll see you at Yarragadee at TIG. 

SPACECRAFT Roger. Yarragadee at TIG. 

PA0 We'll exit S-band blackout at Mission Elapsed Time 

of 7 days, 22 hr, 47 min, and we should be acquiring data through 
the TDRS system at that point. The ground track of the Orbiter 
will bring it across Baha to the northern part of Mexico, right 
across the tip cf the Big Bend National Park, past San Antonio, 
south of Houston, south of New Orleans, about 150 miles south of 
Mobile, Alabama, 175 miles south of Tallahassee, and will 
encounter the Florida peninsula just north of Tampa. Guidance 
navigation and control officer in the control center has verified 
that the Orbiter is in the deorbit burn attitude which is 
essentially flying backwards and upside down. Backwards because 
of retrograde burn where the OMS engines burn against the line of

instrumentation readings. Deorbit ignition occurs in 9 minutes, 
40 seconds. We'll get voice through Yarragadee at approximately 
that same time and look forward to the crew's assessment of the 
deorbit burn. We are 1 hour and 9 minutes away from expected

PA0 Mission Control, Houston. We're about a minute 

away from acquisition of signal through Guam. Weather at the 
Cape advises that there's still some patchy ground fog at that 
location, but nothing that's going to be problematic. It — fog 
has kind of retreated to an area of 50 feet and below and the 
weather forecast suggests that it should be transparent by the 
time the Orbiter arrives there and should not in any way 
seriously obscure their view of the runway. The Guam pass will 
give us data and we'll be able to assess the Orbiter 's rate of 
descant. Of course, the burn doesn't have a very profound effect 
on a velocity, altitude or sync rate this early on. But by the 
time we get to Hawaii, we should have some very noticeable 
measurements to report. The Guam pass is very low elevation, 
only 3.4 degrees maximum elevation over the horizon. So that may 
affecc the quality of the data and of voice.

23 minutes, 33 minutes, Mission Elapsed Time. Data take over 
Guam during that pass, the Guidance Navigation and Control 
officer affirmed to the flight director that the ship's 
configuration looks good and all systems appear in order for 
entry and landing. Guidance officer reported that the onboard 
vectors compared well with the nominal and the flight dynamics 
officer reported that the delta V's, the changes in velocity, 
were at the expected levels. We will acquire signal again 
through Hawaii in 7 minutes 54 seconds. Entry interface occurs 
at 10 minutes 48 seconds from now and we're roughly 41 minutes 
from touchdown in Hawaii. Our NASA Select video shows sunrise at 
the Kennedy Space Center, the runway lights, and weather thinks 
that the sunrise and resulting increasing temperatures are going 
to promote dissipation of that ground fog that the chief of the 
astrounaut office, John Young, reported early. The ground fog 
stays within 50 feet of the ground and is expected to be 
transparent to the crew as they arrive. We are 40 minutes away 
from expected landing at Kennedy Space Center. There will be the 
blackout period as we go through the period of ionization 
buildup. The blackout will begin at, in terms of mission elapsed 
time, 7 days 22 hours 47 minutes and we'll exit blackout 15

15 for its final approach. During its flight across Florida, 
Challenger will be at a very high altitude, above 90,000 feet as 
it passes over the west coast, drop to about 84,000 feet by the 
time it's parallel with Orlando. And still be above 40,000 feet 
as it passes the end of the shuttle runway for the first time, 
although the speed will have dropped to less than the speed of 
sound at that point. Approximately 5 minutes and 26 miles remain 
at that point. And during it's turn to the right over the 
Atlantic Ocean, or turn to the left over the Atlantic Ocean, it 
will drop to an altitude of 10,000 feet. At this point, it'll be 
7 miles from the end of the runway and on a final approach of a 
22 to 24 degree approach which dissipates the remaining energy 
with a preflair and flair maneuver. It takes only about a minute 
to come down the glide slope from above 9,00C feet to flair. 
Then the landing gear will be dropped when it's just 200 feet 
above the runway. Although weather forecasting is becoming a 
more and more exact science, forecasters still have trouble with 
small areas and to help ensure the proper visibility is 
available, two T-38 aircraft in the Shuttle Training Aircraft 
have been aloft several times to see what's happening across 
Florida in general and in the vicinity of Kennedy Space Center, 
in particular. Astronaut John Young who is the head of the 
astronaut office and has been the commander on STS-1 and 9, was 
the one who made a final determination that the landing strip was

KSC This is the Shuttle Landing Facility at the Kennedy 

Space Center. All elements of the landing team are ready and 
standing by for the first landing at the Kennedy Space Center. 
Actually, preparations have been underway at KSC since before the 
first Shuttle flight back in April of 1981. The Shuttle Landing 
Facility has been ready for all of the contingency landings on 
each mission and has practiced hundreds of times for the landing 
which is now minutes away. Many of the people involved have 
participated in landing and ferry operations in California as 
well. At about an hour before the landing, the convoy commander, 
Bill Williams, moved the forward elements of the convoy, called 
the mini-convoy, down to the south end of the runway so that they 
can approach the vehicle from the nose. At the present time, the 
helicopters, department of defense helicopters, are coming in. 
They stand by in case of any contingency where they would have to 
help rescue the astronauts if the vehicle should go off of the 
runway. The remainder of the convoy is at the midpoint of the 
runway and will immediately follow the Orbiter as it passes by 
during the landing. It will then pause at a point about 1,000 
foot away from the Orbiter. As soon as the wheels stop after 
landing, the mini-convoy will move out to a position a few 
hundred feet from the nose of the Orbiter. Ordinarily, they 
would be a little closer than today, but we have heard there* s 
just a slight tail wind of about 2 knots. At that point, a 
safety inspection team will begin immediately to look at the 
front end of the Orbiter using a sniffer which automatically 
analyzes the air for any traces of toxic chemicals. Once an all 
clear is given, the stair truck moves into position at the hatch 
and the astrovan, which is now in place with that convoy, will 
take up its position to take the flight crew back to the crew 
quarters. The shuttle Orbiter, Challenger, will be cutting 
almost directly across the center of Florida. It'll cross the 
west coast at a point near Bayport and follow a general s-curve 
over Brooksville, swing gently to the northeast over Webster and 
Centerhill and then will pass over Lake Mary across the St. 
John's River Valley to a point just north of Mim. It'll soar 
over the Indian River and north of the Shuttle Landing Facility, 
making a left turn over the Atlantic Ocean to line up with runway

PAO This is Mission Control, Houston. There was some 

concern that we might be able to penetrate S-band blacKout with 
the TDRS system, and we've had no success in that endeavor and we 
are still in the blind and awaiting the termination of S-band 
blcickout. This is Mission Control, Houston. NASA Select video 
being shoicn from a T-38 chase plane at Kennedy Space Center beina 
piloted by Charlie Justice of Houston's aircraft operations. 
We're still 5 min away from the predicted end of S-band 
blackout. The patchy fog that was earlier reported at the 
Shuttle landing facility has essentially been reduced into 
intermittent whisps, and is almost completely transparent, no 
problem seeing through it at all. There will be three roll 
reversals performed by the Orbiter to reduce velocity. The roll 
reversals are performed as a factor of velocity when velocity 
reaches 12,960 ft per sec at an altitude of 179,000 ft. There's a 
right roll reversal performed at 139,000 ft f a left reversal and 
a final roll reversal and right reversal at 97,000 ft. Those are 
all done in the automatic mode. The Orbiter will come in under 
auto pilot all the way until it encounters the heading alignment 
cone at Kennedy Space Center, at which time Mission Commander 
Vance Brand will take manual control of the ship. About 3 min 
remaining until the predicted end of the S-band blackout and we 
will resume communications. Mission Elapsed Time now is 7 days, 
23 hr even. About 2-1/2 min remaining until we reestablish voice 
with the crew. This is Mission Control, Houston. According to 
predicted digitals, the Orbiter should have crossed — come 
across Texas by now and just be encountering the Gulf of 
Mexico. And again, according to predictions of travel, the 
vehicle should be travelling at a speed of about Mach 16 at 
195,000 ft. And we have Acquisition of Signal data now coming 
into the control center. We should have voice momentarily. And 
vehicle's traveling at Mach 14. No communications yet due to the 
inability of a good strong forward link through the TDRS 
system. They are getting data. Velocity is Mach 13.7, altitude

of the vehicle. The convoy is made up of; a number of specialized 
vehicles, the mini-convoy coming toward the nose has the convoy 
commander's vehicle, which is modified to provide command and 
communications capability with the control room, mission control 
in Houston and the Orbiter. Four consoles are installed and are 
manned by the commander, his backup, the purge cooling test 
director and the Department of defense on-scene commander. Some 
of the more recognizable vehicles in the convoy are the escape 
van for the technitions who do the initial checkout of the 
Orbiter, wearing self contained atmospheric breathing 
apparatus. A vapor dispersal unit is a mobil wind machine on a 
trailer modified from the standard agricultural wind machine and 
that would be used to blow any toxic propellant vapors away from

the Orbiter. We have a very, very calm day here at the Kennedy 
Space Center and it looks like the — there's going to be no 
problems, the emergency equipment coming up now, the people from 
the escape van getting out to begin their check with the sniffers 
which analyze the air around the Orbiter to ensure that there are 
no toxic fumes which are being released by the Orbiter. The two 
largest trucks in the convoy to the rear of the Orbiter have long 
brooms with trailing lines which makes them look a little bit 
like friendly dinosaurs. The one is a tractor trailer carrying a 
refrigeration unit that provides freon to the Orbiter's cooling 
system to cool the electronic components. The other is a tractor 
trailer carrying an air conditioning unit to provide cool 
humidified air to the payload bay and the fuselage cavities to 
remove any residual hazardous fumes. And also very important to 
the crew is the access vehicle carrying stairs similar to those 
used for aircraft, this one has a small...

and the fuselage cavities to remove any residual hazardous 
fumes. And also, very important to the crew is the access 
vehicle carrying stairs similar to those used for aircraft. This 
one has a small white room at the top to maintain clean 
conditions in the Orbiter. The Or biter is going to be on the 
runway for approximately 8 hours. Right now the camera focusing 
in on the exhaust from the auxiliary power unit, which will be 
powered down approximately 15 minutes after landing. Meanwhile, 
the crew is going through their postflight operations, 

PA0 This is Mission Control, Houston. All the energy 

levels and vehicle performance throughout the landing mode were 
completely nominal. The snip won't be moved until the brakes are 
examined and they're pulled for shipment back to the 
manufacturer. The exhaust fumes visible from the aft end of the 
ship are nominal from the auxiliary power units which are still 
running at speed. Inside Challenger, the crew is throwing 
switches, and going through a postflight configuration to safe 
the vehicle in preparation for egress. Propulsion systems 
officer in the control center verifies that the propulsion 
systems have been secured. 

CAPCOM Houston. Copy. 

PA0 Mission Control now preparing to give the flight 

crew a go for reconfiguration of the data processing sytem 
onboard the ship. 

SPACECRAFT And Houston, if we need any (garble) activation, we 
presume you'll give us a call. 

CAPCOM Roger Wilco, Vance, and you're go for the DPS 

transition. 

SPACECRAFT Roger. 

PA0 This is Kennedy Space Center. Out on the runway, 

the escape suited crew people have been surveying the nose of the 
Orbiter to determine whether or not there was any toxic 
propellants. They have been holding their probes up towards the 
reaction control system which is used for maneuvering the Orbiter 
in space, and would be one of the most likely places to have any 
fumes coming up. They are also now checking around the rear of 
the Orbiter. Everything appears to be going very well as far as 
the function of the APU's, those Auxiliary Power Units, which are 
powered by turbines, and which had a problem on the last mission 
right at the time of landing. As soon as the crewmen with the 
(garble) have completed their work, they will go ahead for the 
truck carrying the stairway to move in. It has a white room 
attached to it, and the crew then will be able to proceed with 
getting ready to open the door in the Orbiter, and have an 



STS-41-B AIR/GROUND TRANSCRIPT t462j 042:12:20 2/11/84 PAGE 2 



exchange of the crew with the support crew. Their support crew 
astronauts today are Shannon Lucid and Mike Smith, and they'll 
take the flight crew's place in the Orbiter to complete 
procedures and to help move the Challenger to the OPF. One of 
the first people who will go into the Orbiter once they are 
allowed to move closer will be the flight surgeon who will check 
over the crew and make sure that they're ready to leave. The 
crew generally will leave the Orbiter somewhere between 40 and 50 
min after the landing. The escape suit personnel can detect 
concentrations of any toxic propellants down to just a few parts 
per million, and are an essential ingredient in the operations

STS-41-B AIR/GROUND TRANSCRIPTS t463j 042:12:27 2/11/84 PAGE 1 



p AO ... of any toxic propellants down to just a few 

parts per million and are an essential ingredient in the 
operation, to just ensure that there is no danger for any of the 
other people in the landing crew as they approach the vehicle. 
The convoy commander stays in constant touch with them as they 
move around the Orbiter, checking each area. Often, they are a 
little more worried about having a very very calm wind sucn as we 
do today because the, any vapors would not be blowing away as 
they normally do. As soon as the crew closes down the gas 
turbines which are part of the auxilliary power units, then the 
rest of the convoy will be able to be moved in position, although 
the APU shutdown comes at approximately 15 minutes after landing 
or just a few minutes from now. The first truck which will 
approach the rear will be the freon truck which is connected 
first and that's followed by the purge truck which flows air 
conditioned air through the cargo bay. The hatch will be opened 
at about 22 minutes after the landing. Appears that the 
technicians in the rear of the Orbiter are moving off, they've 
been checking the area back there and we have the convoy 
commander moving forward. A GO has been given that it's safe to 
be moving closer to the vehicle. Just a few minutes from now, 
right now the stair truck moving up to the Orbiter and then the 
backup astronauts, the flight surgeon and the technicians will be 
able to get busy with getting the door open and getting in and 
checking the crew members. Everything going smoothly with the 
return of the Orbiter here at the Kennedy Space Center. 

CAPCOM ... okay Vance, under GPC 234 power down, we'd like 

to leave GPC 2 up. And so, just that you can scratch out the GPC 
2 reference there. When you do the restringing, we still want 
you to restring them all to GPC 1, GPC 2 will just go to OPS 0 
and we just want to leave up and when you turn one CRT off, we 
would like to make sure that is not CRT 2. What we're doing is 
looking at GPC 2 and CRT 2, so we'd like to leave both those on. 

SPACECRAFT Okay and would you like me to, then I will plug it 
all but GPC 1 but I'll leave 2 on per your instruction. 

CAPCOM That's affirmative, Vance.

peparing the egress from their seats, and should leave the ship 
shortly. 

PAO This is Mission Control, Houston. The propul- 

sion's systems officer here in the control center has affirmed 
that the pressures and temperatures in the forward reaction 
control system are all at normal levels, and there's no evidences 
of leaks from those systems, and they had done their problematic 
during the flight, and of course, accordingly, took extra 
attention during the checkout process here, but they have been 
verified as of healthy and not leaking propellants, or fumes. 

This is (garble) Kennedy Space Center. The change- 
out-crew, getting ready to go up the steps, they've been up to 
the bottom of the steps, and now back at the van. The TV 
camera's taking a look at all of the important areas of the 
Orbiter just after landing. One of the reasons for that is, that 
the, directors here in the firing room, and the technicians who 
have to work on the Orbiter are anxious to know what kind of 
shape it's in. The first consideration, of course, is the safety 
and then they want to get a look at it, because the turn around 
time between flights is getting shorter and shorter as we get 
into this year. The next flight of the Challenger is scheduled 
tentatively for the first week in April. The team from the 
cooling trucks up on their walkway now attaching the freon lines 
to the aft of the Oroiter. This is a cooling system which is 



STS-41-B AIR/GROUND TRANSCRIPT t4G4j 042:12:32 2/11/84 PAGE 2 

used to keep the electronics in the Orbiter cool just after 
landing. The Orbiter kept powered up, so that may of those 
systems are operating. Just in front of the wing of the Orbiter 
is the astrovan which will be used to transport the crew back to 
the crew quarters. People in readiness, photographers for the 
crew (garble) from the Orbiter. The hatch is open now on the

getting out somewhere around 40 min after landing, or about 15 
min from now. People in the firing room, or the control room at 
the Kennedy Space Center, the members of the landing team all 
very happy about the way that the first landing here at the 
Kennedy Space Center has been going.

KSC The crew walking up to the steps now to go up to 

the hatch which has been opened. And they will be going in and 
seeing the crew right now. The change out crews, Shannon Lucid, 
the astronaut Shannon Lucid bringing up the rear there. The 
flight surgeon first who will examine the crew members, Medical 
of checks of the crew are made immediately after landing or as 
soon as possible after landing. And then once they go back to 
the quarters here at v.he Kennedy Space Center, they will be going 
through another physical examination which will include such 
things as checking their blood pressure and then some tests which 
will include checking their vestibular responses to see how their 
adaptation from 0-g back to life in 1-g is progressing. This is 
part of an ongoing study of all the aspects of the adaptability 
of human beings to space flight and then their return. 
Everything preceeding very smoothly here at the Kennedy Space 
Center as the Orbiter is prepared for its return to the Orbiter 
Processing Facility and the turn around for the next launch of 
Challenger. This is Control at Kennedy Space Center, the red 
carpet has been put in place on the runway leading out to the 
steps and it says, "Welcome back to the Kennedy Space Center" and 
it has STS-11 printed there and then that hus been crossed out 
and it says 41-B. This is in tribute to the new numbering system 
which has been put into effect for the Shuttle flights. For the 
first nine flights we used the numerical sequence of the flights, 
STS for Space Transportation System and then 1, 2, 3 through 9 
for the actual number of the flight. And the last flight under 
that system was STS-9 which was the Spacelab mission with 6 
astronauts aboard last November. We have now gone to a new 
system for numbering flights which are keyed to the fiscal year 
in which they fly. If you look at 41-B as the number of this 
flight, 4 stands for the fiscal year which is 1984, 1 stands for 
the Kennedy Space Center. If there was a 2 there that would be 
for Vandenberg Air Force Base out in California and B means it's 
the second flight of this year. So the red carpet actually has 
been ready ever since last summer. It was prepared originially 
to say welcome back KSC for STS-7. Because of weather problems 
there was a waveoff and the Orbiter landed at the Edwards Air 
Force Base in California and had to be ferried back. But this 
should be the first in a long, long string of landings here at 
the Kennedy Space Center. The vast majority will come back. It 
saves turn around time and cuts down on the cost of doing 
business in space. Kennedy Space Center, everything in readiness 
now Lor the crew to emerge from the Orbiter when they're ready. 
They have to undergo a brief examination by the doctor. They 
have to make sure that they're feeling comfortable after getting 
back into 1-g and then they'll come out, come down the steps into 
the astrovan and back to the crew quarters. This is the Control 
Center at Kennedy Space Center. 

SPACECRAFT Okay, it's coming off. And Houston, Challenger.

This is Control Center at the Kennedy Space 
Center. We have the unofficial numbers as far as the touchdown 
and rollout on the runway is concerned. The touchdown time was 
7:15 and 53 seconds Eastern Standard Time. The wheels first 
touched down at the 2,000-foot mark on the runway, the nosewheel 
let down at 5,800 feet, and the stop was at 12,700 feet. So the 
total rollout time was, or distance was 10,700 feet. That's 
unofficial, the chemists have been sweeping over very carefully 
all of the various areas of the tile, taking a look now at the 
nose of the Orbiter to take a look at any damage that might be 
detected. The engineers and the managers who turnaround the 
Orbiter, who oversee that, like to find out as soon as possible 
after each phase of the mission, what has happened. This helps 
pinpoint what caused any knicks or any dinges, or any missing 
tile. There are just a little bit of missing tile back on the 
left OMS pod which they looked at, there is a little, few scorch 
marks. This is something that has been seen before in that 
particular area. But sweeping over the other parts, looks like a 
very very clean Challenger has come back to the Kennedy Space 
Center from space. The, occasionally there's some debris that is 
kicked up at landing. It doesn't appear that there was any. And 
it looks like the crew, headed by Vance Brand, about to come out.

will circularize the orbit at 165 nautical miles. That burn will 
be coming up in about 23 minutes. That will be a 205-foot per 
second change in velocity. Crew completed the check of the 
thrust vector controls, the primary and the secondary systems. 
Those are the controls which tilt the NOSL's of the OMS engines 
to change the direction of thrust that is the method of 
controlling the direction in the spacecraft during that burn. 
The crew completed the vacuum inerting of the main propulsion 
system, the 3 main engines, clearing out all the residual

Elapsed Time. That discussion there between the crew and Mission 
Control about the temperature indication on one of the auxiliary 
power units. It was noticed prelaunch that there was a bias in 
one o£ the transducers, one of the pieces of equipment that sends 
readings to the instruments on what the temperatures are, and 
that is believed to be a faulty piece of instrumentation. And 
there is no action required on the part of the cr*w.

SPACECRAFT Okay, go ahead, Guy, on the APO's. 

CAPCOM Ok, Hooter, we'd like to get a little more cooling, 

so we'd like you to take the APU fuel pump valve coolant bravo to 
auto also. 

SPACECRAFT Ok, Guy, that's done I got the B going also, 

CAPCOM Thank you. And Challenger, Houston, you can ignore 

the last thermal APU message you got, that is due to the pump out 
temps going up, and that's why we had you turn the bravo valve to 
auto. 

SPACECRAFT Ok, we copy that, Guy.

Director Gary Cohen indicating that they would pool the room very 
shortly to get all positions opinion as to whether the spacecraft 
is go for orbit operations, but there seem to be very few things 
out of the ordinary on the flight so far, so we fully expect that

PAO This is Mission Control, we can see the sunshield 

on the Palapa satellite closing over to protect that satellite's 
delicate electronics and other parts from the direct radiation of 
the Sun prior to the time that it will be opened again for the 
deployment of that satellite, which will come about a day or so 
into the flight. The Westar there in the foreground, the 
sunshield is still open on that satellite, and I'm sure they will 
be closing that one shortly. That will be the first one which 
will be deployed and that is later today. In the foreground 
before the, in front of the Westar satellite, you see the top row 
of instruments on top of the shuttle pallet satellite. That 
piece of hardware later on in the flight will be handled by the 
remote manipulator system, the mechanical arm. And off to the 
left of the picture there is the grapple fixture which is the 
point, at which the arm will attach itself and move the SPAS out 
of the payload bay. 

CAPCOM Challenger Houston, be advised you are go for 

vernier jets. And you can go ahead at your convenience Vance, no 
need to wait till 2 + 05. 

SPACECRAFT Okay, go for verniers and we'll do that right 
away. 

PAO This is Mission Control, 1 hour 41 minutes, the 

crew has begun punching the buttons to start closing the 
sunshield on the Westar satellite and we see that beginning to 
move at the present time. Both of the satellites are similar to 
ones which we have taken up earlier on the space shuttle. They 
are the cylindrical design satellites which are carried aloft for 
their first stage of their ride in the space shuttle's cargo 



STS-41-B AIR/GROUND TRANSCRIPT tl6j 034:14:36 2/3/84 PAGE 2 



bay. And then at an appropriate time, they are ejected from the 
cargo bay of the Shuttle, clamps are released and a spring 
mechanism will eject the satellite and its upper stage from the 
Shuttle's cargo bay and then about 45 minutes later, the attached 
solid rocket motor on the satellite then boosts it up to its high 
point of it's geosynchronous Orbit and then later when engineers 
of the companies that own those, or the foreign governments that 
own those satellites are satisfied that they are in the proper 
transfer orbit, then they fire an additional motor which 
circularizes their orbit, and the spacecraft then drift over a 
period of a few days usually into their parking orbits over the 
locations on the points of the earth's surface that they will be 
serving as communications satellites. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston, go ahead.

on, and warmed up and ready for use in the communications. 
Spacecraft communications coming through the Yarrgadee tracking 
station, Western Australia, we have about 3 1/2 minutes remaining 
in that pass. The spacecraft will catch just the edge of the 
Guam station at the beginning of Orbit number 3.

we'll see you for a short pass at Guam, at 4 2. 

SPACECRAFT Okay, Guy, see you there. 

PA0 And this is Mission Control Houston, 2 hours, 36 

minutes mission elasped time. Challenger is passing out of range 
of the Yarrgadee tracking station and we'll pick up again in 
about 5 1/2 minutes or so over Guam. Crew has now moved into the 
regular crew activity plan. The document which lists all there 
activities in detail. Now that most of the set-up preparations 
for on-orbit operations have been completed. Crew is preparing 
to do their alignments of the inertial measurement units. Those 
are part of the system which helps the Orbiter to know its 
position. And they are proceeding with unstowing cabin equipment 
and the assembly of some of the cabin television eguipment. The 
first major event of the flight will be the deployment of the 
Westar satellite. The crew begins to review the deploy 
activities and procedures at about 6 hours, 20 minutes into the 
flight. And the actual deployment takes place at 8 hours into 
the flight. That's the point at which the satellite is ejected 
from the shuttle payload bay and it moves away from the 
shuttle. The shuttle on its own then, does a separation 
maneuver, by firing orbital maneuvering system engines to give it 
a safe distance from the satellite when its own solid rocket 
motor fires off to put it in its transfer orbit. We're about 4 
minutes away from a brief pass over the Guam station and then 
we'll catch Hawaii and that will be, Hawaii will be about 15 
minutes from now. At 2 hours, 38 minutes, this is Mission 
Control Houston.

until we pick up over Hawaii. The crew is continuing to clean up 
all the leftover items from the ascent, and will be continuing to 
set up equipment, unstow the items around the cabin that they 
will be using in flight, and then very shortly be getting into a 
meal preparation time. They will be doing that in about an 
hour. And after that they will be picking up with reviewing the 
procedures and checking out the equipment prior to the deployment 
of the Westar satellite. This is Mission Control Ho^st-on.

Challenger on orbit #3. Things thus far in the mission have gone 
very well, very few problems or even minor system things to 
work. The crew was given some instructions on the manual 
management of the cabin atmosphere. The procedures will be 
somewhat different on this flight, for the management of the 
cabin atmosphere, due to the 2 planned EVA's, in order to help 
cut down on the prebreathe time that has been required on a 
earlier EVA, as shuttle flight 6 where 3 or 3 1/2 hours of 
prebreathe time was required, cabin pressure will be allowed to 
decay and down to a point where there will be much less 
prebreathe time required before the crew goes on pure oxygen at 
the reduced pressure, that is, those members of the crew, Bruce 
McCandless and Bob Stewart who will be doing the spacewalk on 
flight day 5, and the other EVA on flight day 7.

SPACECRAFT WCS EMU mode fan sep 2 makes what you'd call a 
normal sort of a whining noise. I mean the fan makes a normal 
noise with the fan sep in the 2 position. In 1 position it 
doesn't sound like it's coming up to full speed. 

CAPCOM Roger, we copy and concur. It looks like number 1

CAPCOM Challenger, Houston, with a note on the Palapa. 

SPACECRAFT Go ahead, Houston. 

CAPCOM Roger, we have some concern in the data we're 

seeing, we saw rather, on the Palapa heaters, what we'd like you 
to do is, at your convience v iere, perform a depree-deploy PAM ASE 
thermal test. And use the procedure there on page 2-5 of the PAM 
deploy checklist. 

SPACECRAFT Ok, I'll do that, the pre-deploy thermal test on 2- 



CAPCOM Roger, and that's just on the Palapa. 

SPACECRAFT Palapa, copy. 

p AO Mission Control Houston at 3 hours, 32 minutes 

Mission Elapsed Time. Payloads Officer here in Mission Control 
has requested that the crew perform a temperature check on the 
airborne support equipment associated with the Palapa 
satellite. That is all the equipment that stays behind in the 
Shuttle's cargo bay after the satellite is deployed, all the 
cradle and handling equipment that is associated with keeping the 
satellite mounted in place. There was some inidication earlier 
that there might not be - the heaters on that system might not be 
on. They are concerned about, of course, keeping that equipment 
warmed up while there is no Sun shining on that to keep that 
warmed up, it does get very cold and if it's not up to a 
reasonable temperature, they sometimes could have difficulty 
operating some of that equipment which is very important in the 
deployment of that satellite. 



STS-41-B AIR/GROUND TRANSCRIPT t21j 034:16:27 02/03/84 PAGE 2 



SPACECRAFT Houston, this is Challenger, temperature check is 
underway, are you picking anything up? 

CAPCOM Challenger, Houston. Roger, we're getting the data 

and it looks good. 

SPACECRAFT Ok, I understand it looks good 

CAPCOM That's affirmative, Ron. And Challenger, 

Houston. Ron, the data looks good, you can terminate the temp 
check, thank you. 

SPACECRAFT Ok, we copy that. 

Pft O This is Mission Control, 3 hours, 35 minutes. The 

payloads people are satisfied with the data they've seen from the 
temperature check of that airborne support equipment associated 
with the Palapa satellite. They had been concerned that the 
heaters were not functioning, or at least we weren't getting any 
indication from the data that the heaters were functioning and 
keeping that equipment warm. Now after this check they are 
satisfied that those heaters are working and that equipment is 
all in good order. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston, go ahead. 

SPACECRAFT Guy, I'm getting ready to deactivate the APU steam 
vent heaters, do you need them to run any longer?

Botswana though for another 8 minutes if you need us. 

SPACECRAFT Okay, copy. And advise we have the usual small 
cloud of particles flying with us outside the spacecraft. 

CAPCOM Roger, copy. 

PA0 , This is Mission Control, Houston. Challenger's 

attitude right now presents an antenna pointing configuration 
which is less than optimal so we will be in contact through the 
ground station at Botswana for another 6 minutes and at LOS 
Botswana there will still be another about a minute remaining of 
marginal communication capability through TDRS. 

CAPCOM Challenger, Houston. Going LOS here at Botswana. 

Will see you at Guam at 4 plus 15. 

SPACECRAFT Okay Guy. We'll see you there. 

PA0 This is Mission Control, Houston. We've lost 

capability to communicate through Botswana and we're just moments 
away from being out of sight of the TDRS but due to the bad 
pointing angle it's unlikely there'll be any attempt at 
communicating with the vehicle very effectively at LOS. At 
mission elapsed time 3 hours, 52 minutes. The early onorbit 
activities are continuing onboard the Challenger. Commander 
Vance Brand's been stowing cabin equipment at this point and 
setting up for orbit operations. And the other members of the 
crew join in that activity. Pilot Hoot Gibson would be 
performing tests of several alarm lights and fire suppression 
system and deactivating the auxiliary power unit (garble) vent 
heaters. We'll acquire again in about 22 minutes through Guam. 
This is Mission Control, Houston. 

PA0 This is Mission Control, Houston, at 4 hours, 12 

minutes mission elapsed time. We'll have signal through Guam in 
about 3 and a half minutes. Handover has been completed in the 
Mission Control Center and Flight Director Harold Draughon and 
the Crystal Team have assumed duties in Mission Control. The 
handover debriefing was remarkably free of problems as Harold 
Draughon and his team inherited flight control of this mission. 
Discussion principally concerned the LANDSAT Earth station at 
Hawaii which is expected to be recovered shortly and will 



STS-41-B AIR/GROUND TRANSCRIPT t22j 034:16:42 2/3/84 PAGE 2 



ceL'tainly be recovered by ce\ y 6 at which time we're scheduled to 
have downlink television of the Westar predeploy activities that 
is to occur at mission elapsed time 7 hours, 42 minutes. The 
anticipation is that the Earth station will be back online for 
that event and in the event it may not be for some reason they're 
looking at worK-around procedures to recover that. Also, of 
course, camera delta - the color camera mounted on the starboard 
side of the forward bulkhead has proven to be troublesome. It 
doesn't appear to be, have the ability to tilt. The pan 
mechanism operated slowly, more slowly than nominally expected 
and the color wheel is under suspicion and, of course, there's 
discussion on how to check out and alleviate that problem.

SPACECRAFT Hello, Houston. We've got you through Hawaii with 
a squeal in the background. 

CAPCOM Challenger, Houston. We got you loud and clear. 

CAPCOM And Challenger, Houston. The squeal is probably 

due to our uplink of a teleprinter message. We're sending you a 
test message if you want to check it after we get it up there. 

SPACECRAFT Houston, Challenger. 

CAPCOM Challenger, Houston. 

SPACECRAFT Okay, we'd like to explain that we have not as of 
yet hooked up the teleprinter. Reason is that MS panel is hooked 
up to receive deploy audio for the VTR and we haven't quite 
gotten around to realigning all of our comm units so that we can 
devote one unit to the teleprinter, or one plug in to the 
teleprinter which would have to be the PS station. 

CAPCOM Challenger, Houston. No problem with that at 

all. We just want to make sure we can check it out before you 
hit the sack tonight. 

SPACECRAFT Yes. We'd much rather, if you don't mind, we'd 
rather leave the comm configuration the way it is until after the 
deployment and then in the presleep set up for the teleprinter. 

CAPCOM Roger, we concur with that. 

CAPCOM Challenger, Houston. 

SPACECRAFT Go ahead, Mary. 

CAPCOM Roger. This next TDRS pass we'd like to check out 

the encrypted mode. Therefore, when you're ready, it doesn't 
have to necessarily be LOS. We're just going to lose you for a

encryption selection switch to transmit/receive and we'll pick 
you up encrypted through TDRS.

malfunctioning. It, of course, is supposed to be a color camera 
but we're getting only a black and white image from it. The tilt 
mechanism is still inoperative and pan operations appear to be 
slower than nominal. In using aft cameras, the INCO is visually 
inspecting that delta camera presently - seeing if there's some -

inspecting that delta camera presently, seeing if there's some, 
seeing if there's some action that might be taken to recover full 
capability with that unit. Mission elasped time 5 hours 3 
minutes, this is Mission Control Houston. 

PA0 This is Mission Control Houston, the INCO has just 

restated to the Flight Director the nature of the problem 
associated with delta camera, affirmed that the delta camera will 
not tilt, that pan operations are slower than nominal, and that 
the camera appears to hang up at various points, one panning, the 
colorwheel does not run. They took a closer look using the alpha 
camera, to make a closeup inspection of a delta camera, its mount 
and cables, initial visual check didn't reveal any obvious 
discrepancy in that harness or cables, but, some of the backroom 
people will be taking a closer look at that, those pictures, to 
see if they can determine what might be causing that problem. 
They are now discussing whether cycling the circuit breaker that 
controls the tilt motor might have the effect of resetting that 
logic, and might be useful in recovering that function. Mission 
elasped time is 5 hours 11 minutes, this is Mission Control 
Houston.

going to be troubleshooting it again - - 

SPACECRAFT Mary, please repeat. 

CAPCOM Roger, we have at this time on camera delta, no 

color, limited pan, and no tilt, we'd like you to help us out by 
cycling a circuit breaker on R15 Echo. 

SPACECRAFT Okay, standby. 

CAPCOM Roger and on R15 Echo, that's circuit breaker 

camera delta pan tilt, we'd like you to open it for 30 seconds 
and then close it. 

SPACECRAFT Okay, that's camera delta, camera pan tilt, I'll 
open it for 30 seconds and then close it. 

CAPCOM That's affirmative.

CAPCOM Roger, the small, all the small magazines, film 

magazines for that camera, the ASA 400 have been loaded with a 
thin base ASA 400 film and that extends the film run time from 3 
point five minutes and it was previously 2 point five minutes, so 
unfortunately your photo TV checklist for the interior scenes 
show incorrect run times, but you can get the correct run time by 
going by the decals on the tilm magazines.

Bruce McCandless. And plan is to attempt another picture we will 
take with the delta camera which will be the first utility of 
that instrument since we cycled the circuit breaker on it on the 
last rev. 

CAPCOM Challenger, Houston. We're getting a real good 

picture of the GAS can now and as soon as you're finished showing 
us everything you want to show us in the payload bay, INCO would 
like to take control of the cameras back and keep troubleshooting 
the problems on camera delta. 

SPACECRAFT Okay, yes, we're just about through here. We'll 
give it to you in a minute. 

CAPCOM Okay, thanks a lot. The TV shots really help. 

SPACECRAFT Okay, it's all yours. 
CAPCOM Thank you, we copy that.

control of INCO here in the Control Center. The Manned 
Maneuvering Unit now visible in the picture, of course, in its 
stowed position along the starboard bulkhead. And at the top of 
the screen camera delta as being photographed by camera alpha. 

PA0 This is Mission Control, Houston. This is the 

delta camera and clearly it's still providing only a black and 
white image. The kind of half moon affect that darkens the upper 
1/2 of the picture is a product of the inoperative colorwheel in 
that camera which is obscuring the upper quadrant of that lens. 
So initially it would appear that having cycled the circuit 
breaker on the last rev has had no effect at least on the color- 
wheel and we'll stand by to see what's happenned to the tilt and 
pan mechanism.

PAO ~ and as a by-produce of the antenna location and 

pointing. We're now 1 hour from payload deploy and the Mission 
Control Team here recognizing some keystrokes and commands that 
the crew is performing in preparation for those deploy 
activities. For the deploy, the crew will be located as 
follows. Mission Commander Vance Brand will be at the aft 
starboard station in the flight deck from where he can control 
the Orbiter's attitude with the rotational hand controller. 
Pilot Hoot Gibson will be in the forward right seat. MS-1 which 
is Ron McNair will be in the forward left seat, and MS-2 Bob 
Stewart will be at the aft crew station with Vance Brand. 
Stewart will be at the aft port or the payload station. Mission 
Specialist Bruce McCandless will be in the flight or in the mid 
deck of the Orbiter and will not be performing activities 
associated with the payload deployment, but in fact will be 
working on student experiments. This is Mission Control Houston, 
Mission Elapsed Time of 7 hours, 1 minute. The gimbal check 
proved nominal. Mission Specialist Bob Stewart is performing 
sequence control assembly power up and also making a backup check 
of the sequence. 

CAPCCM Challenger, Houston. 

SPACECRAFT Houston. 

CAPCOM Roger, Challenger, Hooter, that gimbal check looked 

real good to us. 

SPACECRAFT Ok, thank you, Houston. 

PAO To continue, Bob Stewart is also making a backup 

check on the sequence control assembly that is associated with 
the payload assist module. That CRT-3, in the co-nnander's seat 
of the flight deck, Mission Specialist Ron McNair will be making 
some keystrokes preparing the vehicle's computer system for the 
deployment activity. The deployment, of course, is a sequence 
that is affected by those 4 crewmen working in concert together 
rather than any one member of the crew. Payloads Officer 
advising the Flight Director that they've been watching Bob 
Stewart perform the check out of the sequence control assembly 
and all those functions and temperatures looked very good. The 
end of deploy procedures officer in the Mission Control Center 
has reported to the Flight Director that the pre-deploy checkout 
operations are proceeding on schedule and that the data shows 
approximately where they are in the PAM-deploy checklist, and for 
those of you following along in that document, they're on pages 
3-8 and 3-9 and holding. This is Mission Control Houston, it's 7 
hours, 8 minutes, Mission Elapsed Time, we're LOS through TDRS, 
50 minutes from deployment of, scheduled deployment of Westar at 
about 10 minutes from now, the pilot Hoot Gibson will be at his 
position on the starboard, forward seat in the flight deck. 
He'll be making some keystrokes inserting commands in the digital

auto-pilot onboard the vehicle and the pilot and the commander 
will then configure the cabin light for TV to facilitate optimum 
viewing of the deployment sequence on the video tape process. At 
25 minutes before the deployment there will be some critical 
temperature checks made of the payload assist module and the 
payload bay flood lights will be configured for the TV recording

deployment, there will be some critical temperature -hecks made 
of the payload assist module. And the payload bay floodlights 
will be configured for the tv recording of the deployment 
process. And again we do expect to get tv through Hawaii but the 
quality of that video is suspect at this point. This is Mission 
Control Houston, at 7 hours, 19 minutes, Mission Elasped Time, 
were now 40 minutes from that deployment and according to the 
timeline we'd be picking up activities once again on the 
deployment checklist. We've had some keystrokes principally by 
Pilot Hoot Gibson at this time, but in as much as were in the 
blind why we will have to wait until we acquire at Guam to verify 
that adequacy of preparations up to this point. Mission Elasped 
Time 7 hours, 19 minutes, and we'll acquire through Guam in 10 
minutes, this is Mission Control Houston. 

PA0 This is Mission Control Houston, at 7 hours, 28 

minutes, Mission Elasped Time, 2 minutes away from AOS through 
Guam, and we'll be able to determine the success of predeploy 
preparations up to this point and are probably going to give a 
reminder to the crew that we will be taking television through 
Hawaii during for that 8 minute duration over the islands, and 
watch predeploy checkout activities on NASA select. This deploy 
will be the 6th use of payload assist module deployment on Space 
Shuttle, 2 on STS-5 for the Satellite Business System and ANIC, 
on STS-7 an ANIC and a Palapa, and on STS-8 and INSAT IB. So 
Westar will be the sixth in that series, of course, all prior to 
previous ones have been nominal and in addition to these of 
course, there have been a little series of 10 or so PAM 
deployments they used on delta vehicles dating back to 1980, on 
the unmanned side of the house. Should be getting voice 
momentarily through Guam, and get the crews report on status of 
deployment preparations. At Mission Elasped Time 7 hours, 29 
minutes, this is Mission Control Houston.

activating payload bay floodlights to prepare for visual 
verification of predeployment operations. And Mission Specialist 
Ron McNair, at approximately this time will be checking the 
batteries aboard Westar which of course had been supplemented by 
Orbiter power and assuring they are in a fully charged state by 
deployment. And Mission Specialist Bob Stewart will be 
deactivating the PAM heaters on the airborne support equipment. 
And at this point verification has been made of, concerning the 
deploy configuration, the IMU's has been aligned prior to the 
start of deployment

concerning the deploy configuration, the IMU's have been aliqned 
prior to the start of the deployment checkout. The deploy and 
reparation, the pads, their preliminary advisory data have been 
voiced up, the deploy time in Greenwich Mean Time has been set in 
the General Purpose Computers by a table maintenance buff t 
update from the ground. TV cameras and motion picture cameras 
have been configured, closed circuit TV's have all been 
activiated and positioned by now and the crew will have selected 
the best closed circuit camera for deployment monitoring. 

CAPCOM Challenger, Houston, we're about 30 seconds LOS 

nere at Guam, we'll talk to you through Hawaii at 7+42, and we'll 
be taking live TV there. 

SPACECRAFT Ok, we'll see you then, and we'll have some TV for

PA0 , This is Mission Control Houston, we're LOS, we'll 

acquire at Hawaii in about 7 minutes. Mission Elapsed Time at 7 
hours, 34 minutes, and we're just less than 25 minutes from 
deployment. We expect TV through Hawaii, and the expectation is 
that the crew will select camera alpha to monitor the 
deployment. Cassettes, video cassettes will have been installed 
in the video tape recorders onboard. 70-mm Hasselblad is mounted 
in the aft starboard window, and its proper exposure settings to 
record the deployment. A 16-mm motion picture camera is also 
mounted in the aft window and another l'e-mm will be hand held by 
3ob Stewart for photography of the deployment out the overhead 
windows, and the Cinema 360 camera, there are 2 carried onboard 
one in the get-away special cannister in the payload bay, and 
another in the flight deck. And the flight deck camera will have 
been mounted on a panel for in-cabin scenes during this 
deployment, and window shades will have been removed and stowed 
by this point. We're 22 minutes from deployment, and the pre- 
.♦eploy sequences begin in earnest at about 15 minutes. Ron 
McNair executes an ITEM 2 on the Cathode Ray Tube Displays in the 
commanders seat onboard the vehicle, that sequence, that execute 
has the effect of starting the sequence. The sunshields which 
have been closed to this point will open. Restraints will be 
removed from the payload assist module, and spinup will occur, a 
nominal spinup of 50 revolutions per seconds is considered is to 
be the objective, of course, and the speed will be monitored to 
be sure there are no over speeds or under speeds. This is 
Mission Control Houston, at 7 hours, 40 minutes, we're just a 1- 
1/2 minutes away from Acquisition Of Signal through Hawaii, 18 
minutes remaining to deployment, and shortly after AOS , Mission 
Specialist Dr. Ron McNair will perform that ITEM 2 execute 
commanding the mechanical sequence of the initial deployment 
activities including opening of the sunshield and spinup of the 
stabilizing mechanism at a rate of 50 revolutions per minute. TV

the affect of opening the sunshield on those payload bay, on the 
payload assist module and begin the spinup activities Safety 
restraints are presently affirm to be in by the Payloads Officer 
in the Control Center. That item 2 execute will remove those 
restraints so we'll be looking for verification that the 
sunshield has opened, that the restraints have been removed and 
that spinup has commenced and affirmation of the spinup of 50 
revolutions per minute.

to the OMS separation burn that Challenger will perform to remove 
it to a safe distance from the Westar and Payload Assist Module 
as the perigee kick motor is fired. That burn occurs at 13 
minutes, 13 and 1/2 minutes from now.
