Just completed at the T minus 1 hour and 30 minute mark were a simulated first motion signal test. During this test the simulated signal indicating first motion is sent to the Eastern Test Range and also to the Mission Control Center in Houston. During the actual lift-off this first motion signal starts the countdown clock in the plus time at those two areas. Recently completed were checks of the emergency detection system. This is a system that is designed to sense and react to any emergency situation resulting from a launch vehicle malfunction during the early portion of the powered flight. During most of the first stage flight the EDS, as it's called, provides the capability for automatically aborting the mission. The auto abort system is turned on at lift-off and disabled by the crew about 2 minutes into the flight. The system senses such things as loss of thrust in first stage engines or excessive rates in pitch or yaw. The test takes about 30 minutes, it's conducted with the spacecraft commander, Pete Conrad, and the launch vehicle people here in the firing room. During the test, simulated emergency conditions are sent to the vehicle and lights in the spacecraft light indicating what the nature of the emergency is. We have one more hold planned in the countdown, that's at the T minus 15 minute mark. Nominally that will be for 2 minutes duration. AT that time the clock will be updated to correspond with the orbiting Skylab overhead. The close out crew at the white room area is securing now for their cabin purge and leak checks. Every­ thing continues to move along smoothly there. Now for a status report from the Mission Control we go to Houston. PAO This is Skylab Control at Houston at minus 1 hour 24 minutes and continuing with the count. In the Mission Control Center two teams of flight controllers now on station at their consoles proceeding toward the launch of Skylab 2. The crimson team of flight controllers headed by Flight Director Don Puddy managing the orbital workshop systems, and the purple team headed by Flight Director Phil Shaffer, which will be in control for the manned launch and rendezvous phase of the flight. The Saturn workshop is presently in an orbit of 239 nautical miles by 234 nautical miles. An average workshop cabin temperature now reading 120 degrees. At the time of ignition, the workshop will have passed directly overhead and should be approximately 780 nautical miles downrange at the time of ignition. Flights Dynamics advises that Skylab 2 will be launched with an azimuth of 47.58 degrees. CAECQM^for our launch will be Astronaut Dick Truly.... We're at 1 hour 23 minutes, continuing with the count at Mission Control Houston, this is Skylab Control. END OF TAPE �SL-II MC2/1 Time: 07:02 a.m. CDT, T-00:55:00 GET 5/25/73 PAO This is Skylab Launch Control we're at T minus 55 minutes and counting. T minus 55 and counting in the first manned mission in the Skylab program. The closeout crew at the pad is now clearing the pad area. Before leavinq, the pad leader confirmed that the white room area had been com­ pletely secured, all loose equipment removed and stowed and the tool and supply cabinet secured. There is an environ­ mental control hood which attaches between the white room area and the spacecraft. That's also now been secured. He reported back that the white room now ready for swing arm retract. This will happen at the T minus 45 minute mark in the countdown and actually the swing arm will come back to what is called the 12 degree position. This is the standby or park position. And it will remain there until the final minutes in the launch. At T minus 5 minutes it will swing back to the fully retracted position. Also underway at this time the superintendent of range operations calling in to Bill Schick the Test Supervisor indicating that the launch danger area has been declared clear for a launch. In the spacecraft itself pilot of the mission, Paul Weitz been working with ground controllers on spacecraft communications fre­ quency and power readouts. Weitz selected as an astronaut in 1966 was a member of the astronaut support crew for Apollo 12. That Apollo 12 mission also commanded by Pete Conrad. Weitz ^ \,degree tn aeronautical engineering. He's a Commander in the Navy with approximately 4000 hours of flying time. Our weather at this time is generally cloudy in the launch area, however, some of that cloud is expected to dissipate during the next hour. For launch time the weather men are predicting broken clouds. These will be in several layers. 5 5uPSv.° upper layers expected to be about 15,000 feet and the base of the lower layer is about 6,000 feet. Winds at launch time are expected to be approximately 10 knots from the southwest and the temperature about 78 degrees Fahrenheit. Closeout crew now cleared the area. T minus 53 minutes 40 seconds and counting this is Kennedy Launch Control. END OF TAPE �SL-II MC3/1 Time: 07:13 a.m. CDT, T-00:45:00 GET 5/25/73 PAO This is Skylab Launch Control; we're at T minus 45 minutes and counting. We'll expect the swing arm to be retracted shortly. Mark there comes the swing arm, moving back to the park position; this is a 12 degree park position, approximately 10 to 15 feet from the vehicle. It will remain there now until approximately 5 minutes in the countdown, and at that time it will be moved back to the full retract position. Also underway at this time are interroga­ tions of the C-band beacons. These are two beacons aboard the instrument unit of the vehicle. During this test these are simply checked, the beacons are checked to insure that they are being tracked and will be tracked during the powered phase of flight. During powered flight the beacons give position data as well as speed and acceleration. Now that the swing arm has come back, the launch escape system atop the command module will be armed. Stoney, Astronaut Bob Crippen, will position the mobile launcher elevators at the 320-foot level in what is called the egress mode. The - Bob Crippen is the Astronaut communicator name that is called, he is called Stoney, will be in the Launch Control Center. Crippen was also a member of the crew which entered the altitude chamber for the Medical Experiments Altitude Test, 56-day test run in Houston last July. A short time from now we expect the science pilot, Joseph Kerwin. We'll begin arming the service module reaction control system. To do this, he actually opens valves and allows the hypergolic fuels to flow down through the lines down to the engines. The countdown has proceeded very smoothly this morning. Now at T minus 43 minutes 4 sec­ onds and counting, this is Kennedy Launch Control. END OF TAPE �SL-II MC4/1 Time: 07:30 a.m. CDT, T-00:27:00 GET 5/25/73 PAO This is Skylab Launch Control. T-27 minutes 59 seconds and counting. Preflight command system tests for the mission control center in Houston have just been completed. Also just completed at this time was a final level adjustment of RPl, the fuel used in the first stage. RP1 is actually loaded prior to the countdown demonstration test and replenished last night before cryogenic loading. This level adjustment made here during the final hour of the count is necessary to take into account temperature and humidity and to assure us a full flight load. Cryogenic loading of course, also completed earlier this morning and topping continues. The astronaut crew completing their preflight check list in the command module at this time. Now we'll switch to Houston for a status from the Mission Control Center. PAO This is Skylab Control Houston at -27 minutes and counting. Flight director Don Puddy of the workshop team is going around the Horn with his team in the mission control center for a GO/NO GO for Skylab launch based on orbital workshop data. Given a GO at this time for the launch of Skylab II. The workshop is now passed out of range of the Honeysuckle tracking station. The next station to acquire will be Texas on this the 156 revolution. Meanwhile the Shaffer team of flight controllers has been given a GO for the start of the terminal count which is now in progress. The displays of mission control center in Houston now selected for the launch of Skylab II. At -26 minutes and continuing with the count, this is Skylab Control Houston.

Science Pilot Joseph Kerwin at this time reading out temperatures, pressures, and quantities in the service module reaction control system quadrant. Cryo­ genic fuels aboard the launch vehicle continue to be topped. We have one more hold as we aim toward our 9:00 a.m. lift-off. That's a nominally 2 minute hold and we're coming to the T minus 15 minute mark. Our countdown continuing to go smoothly at this time, T minus 21 minutes 30 seconds and counting, this is Kennedy Launch Control. END OF TAPE �SL-H MC6/1 Time: 07:42 a.m. CDT, T-15 min GET 5/25/73 PAO This is Skylab Launch Control we're now at the 15 minute mark in the count, T minus 15 minutes and holding this is a planned hold period nominally for 2 minutes. It's a final clock adjustment to assure lift-off at the proper time in conjunction with the orbiting Skylab overhead. Interrogation of radar beacon number 1 has just been com­ pleted. When we come out of this hold at the T minus 15 min­ ute mark the spacecraft will go to full internal power. Actually the fuel cells have been supporting the spacecraft at this time but they have also had a backup of ground support power. In the command module the crew completing their checks They actually on their display panels have some 24 instru­ ments, 566 switches, 40 event indicators and over 70 lights. Inside the command module they have approximately 70 cubic feet per man. This is a little larger. A little more room than one would have in a compact car. Once they get into Skylab, however, that will change considerably. They will actually have about 59 times the volume in Skylab that they have to work in in the command module. At this time Stony, the astronaut communicator Bob Crippen here in the Launch Control Center, the Launch Operations Manager, Paul Donnelly and the Spacecraft Test Conductor, Bob Reed have switched to the astro launch circuit for communications checks. This is the circuit which will be used by the astronaut crew and these members at launch time. When he came aboard this morning Astronaut Pete Conrad commented that he hoped the launch team planned to blow the clouds away by 9 a.m. The clouds, in fact are breaking up somewhat at this time. Bob Reed, the Space­ craft Test Conductor, indicated that if the clouds weren't all blown away he was sure that they would do it as they lifted off. We're preparing to pick up the countdown now.

Various personnel now reporting in to the spacecraft test supervisor Bill Schick that they are ready and GO for launch. Bob Reed the spacecraft test conductor has indicated that the spacecraft is GO. Launch operations manager Paul Donnelly reports GO and the director of launch operations Walter Kapryan also has reported GO for a launch. Final computer programs are now being run to place the launch vehicle in a launch mode. In the space­ craft the final action to be taken there will be at the T minus 4 minute mark. Paul Weitz will turn on the spacecraft batteries and at T minus 45 seconds, the last action to be taken by the crew will be taken by Pete Conrad when he makes a final guidance alinement. We're coming up now to the 5 minute mark. At that time the swing arm, swing arm number 9 will come back to the full retrack position. Actually for the Saturn-IB there are only 5 swing arms. The number 9 designation comes from the earlier launches using this same mobile launcher, using the Saturn-V. Swing arm now coming back to the full retrack position. It will remain in that full retrack position now for the rest of the countdown. At T minus 3 minutes and 7 seconds the count will go on the automatic sequencer and will be carried out automatically from that time on.

The launch sequence has started. We're now on the automatic sequencer, and the countdown will be run now by that automatic sequencer. The number of functions are carried out by the sequencer, and they must be carried out in the proper order, or they would be automatically shut down. Also, at the same time, the launch crew here in the firing room will continue to monitor their various readout temperatures, checking the gages for pressures and rates. They could override the sequencer if necessary. At the T-3 minute and 6 second mark, the automatic sequencer terminated the liquid oxygen and liquid hydrogen replenishing. These cryogenic fuels have been being replenished since fueling was actually completed early this morning. After this termination the fuel tanks will be pressurized. Actually pressurization has now started. The second stage liquid oxygen tank has now been pressurized, and the first stage fuel tank also has been pressurized. Now passing the 2 minute mark in the countdown. The vents closing and the pressurization is taking place on the 2 stages of the Saturn IV. At the T-l minute 15 second mark, Paul Weitz will trip two switches in the command module, placing the spacecraft batteries on line. These batteries will give added support to the fuel cells and also act as a backup to the fuel cells. Fuel cells also on line at this time. T-l minute 30 seconds and counting. Our count­ down continues to go smoothly. Also during the automatic sequence we'll switch to internal power. We've been carrying the power from a ground source up to this point to save on the flight batteries.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

Stand by one, we're trying to get the PB on the VTR and Pete will have a chat Wlth c°U* C Skylab, Houston. We've got about 4 min­ utes left on this pass. Can you give us a report? CDR Be right with you, Houston. Okay, Houston. We had a clean deploy­ CDR ment as far as rods clearing and e^ryhthing, but it s not laid out the way it's supposed to be. And we ve gotpic tures of it on the VTR for you. Now right at the moment, we've operated voided the rod in and out a couple of inches short stroke-wise rapidly, which has improved the deploy­ ment. But the problem seems to be that the folds in material have taken too much of a set. And it is more fully deployed in the front across the upper skirts. But, there are two folds emanating from the set, 3 folds emanating from the center deployment plate; one to each side an one towards the base skirt. So, in effeet,we 1have a trap­ ezoid which is the smallest dimension toward the base of the vehicle. Now, that's as far as we We gone. We:re open for suggestions. I have the feeling that if we pulled it all the way in close to the vehicle that it would touch in the back and along the sides. It might possibly "SlP the folds out of the material and if we did push her back out again and gently oscillate it in and out, as we have in the past, which seems to improve it. But, I think we ve gotten about as much out of it as we're going to get. My guess is we've only got about 12 to 14 feet at the back end with perhaps 18 to 20 at the front end.

There's to be the poles that are pointed back toward the ATM should be the ones that have a length without fabric on them. CDR That's the way it is. CC That's the way it should be. CDR If you are able to dump our TV we, I think, give you a pretty good TV of it. It just does look to me like the end aft toward the aft skirt has got three wrin­ kles. One coming between the aft skirt line and one on each side running along you know running outboard to the side. And that it's pinched the fabric, you know. It's taken a permanent set. And the front end, which has the strings on it, that's pretty well deployed. CC Okay, we're about 15 seconds from LOS. We'll think about it and we'll talk to you at Vanguard. We hope to have a plan then. Vanguard is coming up at 30. CDR Three zero, Roger. CC Skylab, Houston. If you can still read, we'd like to terminate that Bat A charge and get Bat B to charging. And also, if anybody is free, we'd like to start them on the water flight servicing. CDR Okay, we were just going to ask you that. PAO This is Skylab Control. We've had loss of signal through the Hawaii tracking station. Coming up on Vanguard in 21 minutes. There was considerable applause in the viewing room from the people who are involved in designing, fabricating, testing the parasol when it was re­ ported that it had deployed with a few wrinkles in the after end of it - end pointing - facing toward the telescope mount. Meanwhile, here on the ground, discussion is underway on how would be the best way to try to shake the wrinkles out. And, hopefully, over Vanguard, some word will be passed up to the crew on how would be the best way to correct the problems and get the full 22 by 24 foot dimensions out of the parasol for the optimum solar shading.

Skylab Control standing by. CC Skylab, Houston through Vanguard for 9 minutes. CDR Go ahead. CC Roger. First off, we'd like to get Joe to tell us what he saw out the window. We would like to know if the rods are approximately in the same plane. SPT Well, we don't think so, Houston. We can see the ends of all the rods. It's completely free of anything and there's nothing hanging it up. SPT And if you want to know what it looked when it deployed I can see the thing stickin up, bunched in the middle, billowed a little bit at the top and at the bottom, and when they deployed it, all four legs came up. The front legs, that is, the forward ones closest to the command module, came up smartly. It looks as if they actually went over center a little bit, then bounced back. The back ones did not come up, it looked like, all the way - didn't come to 90 degrees. They went slowly and they just kind of drifted to a stop. CC Okay. What kind of an angle do you think they made with the plane of the first two rods? SPT It's your guess, but I guess 30 degrees, something like that. CC Okay, we would like for the CDR and the PLT to go back in the workshop and pull her in and we'd like for you to pull as many rods in at one whack. Undo the rod break and bring in about three at a time and them remove them and we want you to complete the procedures down to step 43 so you've done a full retraction and got the rod A configuration proper. And we're going to be doing a nominal H-cage at the end of this pass and we want to get it in close. SPT It worked. CC Skylab, Houston. We'll give the time for that reset so that you can be sure and have the rod brake on when we start it. �SL-II MC-111/2 Time: 20:28 p.m. CDT, 1:12:28 GET 5/26/73 r£T Skylab, Houston the time for the reset is 01:36.

Skylab cluster crossing the east African coast in the straights between the Island of Madagascar and the continent of Africa. Here in the Mission Control Center there's a great deal of confidence that the recently deployed Skylab parasol will have a good effect on the internal temperatures of the Skylab workshop. Johnson Space Center Technical Services Division Chief Jack Kindsler just spoke to the group of people in his division and other elements of the center and support contrac­ tors in the viewing room, and expressed the belief that as the parasol gets warmed up by the Sun during the next couple of dayside passes, the wrinkles in the after end of the canopy which apparently were set by the cold soak during the early part of the deployment will indeed flatten out. And that the parasol will provide the designed effect of lowering the temperatures, and acting as a parasol in name and indeed for the Skylab workshop. 37 minutes to Hawaii.

And flight controllers will be observing the workshop temperatures during the next couple dayside passes to see if there is a trend of temperature reduction in the workshop structure and in the atmosphere. It will probably take at least 2 revolu­ tions for the temperatures to begin a downward trend. And hopefully through the night, the workshop will be in a comfortable temperature, by the start of tomorrow's crew workday. People here in the Control Center are well sat­ isfied with the deployment of the Skylab parasol. And as the inventor of the parasol mentioned in his pep talk to the people in the viewing room who had built and tested the device, he felt that the wrinkles seen in the after end were a result of cold soak and that as the Sun warmed up the canopy, the wrinkles would flatten out.> We're looking now at a handover from Flight Director Neil Hutch­ inson to Milt Windier at about 10:15 central time. And anticipating a press conference shortly there after, per­ haps 10:30 p.m. central. Participants will be William C.

We'll see how the solar sunshade or Skylab parasol is working as we read temperatures on this pass. See if they're coming down. SC See you over Hawaii for 10 minutes. CC Okay, we got a lot of things we want to talk about on this pass. I guess I'll get on with it. First off we're planning a medical conference at Vanguard, which is about 03:04. That will be the next station contact after this one. The next item is that we have a requirement that one of you wear the OBS tonight, since we don't have any (garble) in the Command Module, and depending upon the CSM fan, we're recommending the SPT. CDR Okay. CC And for the SPT, we'd like to get his opinion on - we can only - we can't dump all of the VTR tape to get that pictures back of the parasol, and we'd like to know whether it would be better to lop off the first part or the last part. In other words, about where in there was the pictures of the deployed parasol? SPT Hank, if you might get the pictures of the actual deployment at the beginning, and the pictures most actually representative of the configuration in which we ditched it down are at the end, and you can take your choice. CC Okay, thank you. SPT Hey, Hank. CC Go ahead. SPT I got to apologize profusely, but I inadvertently opened the circuit breakers to the amp hour integrator number 8, and it's reset to zero onboard. CC Roger. Copy. CC And our maneuver plan is here, we're going to take a look at the temperatures, and we think they're coming down. We're prepared to command a solar inertial here over Hawaii. Just let you know, and we're also prepared to back that up at Vanguard as a last choice. SPT You say you think they're coming down or if they're coming down. CC Well we're looking at them now to see what they look like. SPT We just finished weighing all the mol sieve heat exchanges. What do you do with them? Just stand by until tomorrow. �SL II MC-114/2 Time: 21:36 CDT 01:13:36 5/26/73 CC Okay, while we're getting an answer on that, we'd like to know how far you got in the - your checks, have you done the quiescent panel yet?

The rest of it's done. BAT B is being charged. I just did an 02 purge. CC Okay, what we're getting at, Pete, we we're wondering how you feel about trying to get the VCS dump in tonight, and get some circulation going. CDR Boy, you bet, we can do that. CDR Hey, if you think those temps are coming down, and that will help any, that's no strain. We're in good shape up here. CC Okay, then, in that case, we'd like fot you to do Step 1 & 2 on Page 2-62, and following that, on Panel 390, I'd like to get all four OWS heat exchanger fans on. Just place all four of them to'on'. And tomorrows flight plan, of course, we'll delete that part of it ahd do Steps 3 & 4. CDR You say you wanted the OWS heat exchanger fans on or off? CC On. O N.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

CC Okay, we've got a pass probably in about oh. Vanguard coming up. We'll be trying to work that then at around 4:46. SPT Okay, what is the temperatures doing in the workshop there? CC I'll try to get a report for you on that. Meanwhile, we'd like to find out if you did put the SEVA report on channel A or B. We're dumping A right now. We didn't see it there last dump. SPT We haven't gotten to the evening reports. It is still about the middle of the afternoon for us. Pete and Paul are working pretty hard on the condensate system They're dleaning up the command module and stuff like that. CC Okay understand. We just want to make sure you did know that we were recording channel A. And you will be putting the medical status report on channel A for us later. Is that correct? SPT Yes, and we're going to have a couple of large (garble) I think because we have enough other problems coming up. We're going to stick with it. We are in good shape andwe've had our private medical talk. And we don't have any­ thing to report. CC Roger. I think all we are interested in there is the food and, you know, whether you took any drugs or not and that kind of stuff. SPT We are eating like hogs and drinking lots of water. CC Very good. SPT - this evening status report and we'll get as much of this to you as we can. CC Roger Joe, understand. If you could also put down, we would like sort of a relative amount of time spent between the airlock module MDA and the workshop today. I guess they're kind of interested in what kind of tempera­ tures you were experiencing. You can put that on channel A. SPT My off the cuff answer (garble) they can apparently get thatby looking at my biomed tonight. CC Okay, they were kind of interested in that for the other guys too though Joe. Okay, the skin tents have dropped about 70 degrees. We're going to have LOS here in about 1 minute. We're going to be over Vanguard at 4:46. We were kind of hoping that you guys were going to bed. Do you want us to give a call there or not? �SL-II MC-116/3 Time: 23:32 CDT 1:15:32 GET 5/26/73 SPT yes cc You'want us to give you a call at Vanguard understand.

END OF TAPE cintrol �SL-II MC-117/1 Time: 23:47 CDT, 1:15:47 GET 5/27/73 CC Skylab, Houston. How do you read? CDR Loud and clear (garble). CC Okay. We're a little bit garbled. I'd like to talk about maneuvering here a little bit if I could, to Joe. SC (Garble) CC Roger. We are prepared to put a maneuver to try to reacquire solar inertial and there's some confusion on our part about whether we should go plus or minus Y. We understood you to say plus Y awhile ago. We think it's minus. Will you confirm that? SPT Okay, let's talk about it. Maybe I'm getting it wrong. It would appear to take - to require a pitch above the Y axis. I was going to say toward the CSM, if that makes any sense to you. As I stand facing the CSM and look up the Z-axis, the Sun is forward of the zenith. It's in other words, it's between the plus-Z axis and the plus-X axis. CC Okay, that's a plus-Y. That - we got up there on the top of the MDA - we got the plus-Y axis indicated and that still sounds like a plus-Y rotation to us. SPT Well, I thought it was. What have you got for X? CC Okay, about plus 15 degrees. SPT That sounds right. CC Let's go back and review that again. You say the Sun is between the CSM and the ATM? SPT Yes. That's right. CC That's a negative-Y rotation. CC You're right, you're right. Okay, it is a plus-Y rotation. SPT Nyaaa nyaaa. CC Okay. Okay, what we're going to do is put in a plus-Y rotation of 40 degrees and a plus-X rotation of 15 degrees. We got a maneuver time on it of 15 minutes. If we don't hack it this time we'll probably suggest turning it over to you. And before you would ever try to do it, you would need to - before you ever select solar inertial mode, you need to make sure that you put in a command to initialize your strapdowns because they're way off right now. SPT Understand. CC And for Pete or Paul, I guess maybe we'd like to ask a question. Is there any reason that duct 1 flow would be down now. We've got a substantial drop in it. SPT (Garble) MDA. Oh, duct 1. No, not that I know of. I can go check it if you want. SPT Talking about duct 1 in the workshop, right? �SL-II MC-117/2 Time: 23:47 CDT, 1:15:47 GET 5/27/73 CC That's affirm. SPT We didn't do anything. I'll go check it. SPT If you're ready, let me give you a status of our ECS, all right? CC Okeydoke, go ahead. SPT Okay, we presently are running both condensing heat exchangers A, and mol sieve A and B. We just finished a condensate dump into the waste tank. We have two ducts. Ducts 1 and 2 were running in the workshop. We got the airlock module duct fan on HIGH with all the mol sieve air going to the workshop through that diverter valve. We've got the MDA fans on low, the CSM fans on low, and the three AM circ fans we just turned on about 5 minutes ago on LOW. CC Okay, we copy. We got all four fans running in ducts 1 and 2. Is that affirm? SPT Hell I turned them on. I'll go check. CC Okay. SPT You still want to leave just ducts 1 and 2, leave 3 off, right? CC That's affirm. SPT Okay. You say duct 2 is the low one? CC Negative. Duct 1. SPT Okay. CC Joe. We have initiated a new one now. And it might be - if you got time, it might be wise to take a look out and see. Looks like we're going the right direction. SPT Roger. cc And CDR, Houston. If you got a chance, I guess maybe we'd like to get an idea about how much longer you guys are planning on working. CDR I'm trying to make dinner. I don't think we're going to work very much longer. I would like to go to bed, but everytime we do, something comes up. Duct 1 for 600 plus; CSM. cc Roger, understand. Duct 1 600 plus; CSM. CDR Duct 2 (garble) 550 and duct 3 (garble) 75; CSM. CC Roger, copy. CDR And, Crip, as soon as we get into sun­ shine, I'll give you a hack on the maneuver. I guess it'll be gone by then. CC Roger. Also be advised that we're starting to get a lot of feedback out of those SIAs. If you might could do a little adjustment. I don't know whether it's ringing there or not. CDR Yeah, it is. CDR Hey, Crip, how much temperature skid drop are you getting. Does it really look like that the shield's working? �SL-II MC-117/3 Times 23:47 CDT, 1:15:47 GET 5/27/73 CC That's affirm. It looks like it's really coming down. Did you hear my last call back when we were - at Guam I gave you a call that we'd dropped 70 degrees. CC That's skin temp. I'll probably get a hack for you - what the workshop temperature inside - what we think it is. Okay, the next pass is going to be coming up at Ascension at 05:00. And would you like us just to forget that call? CDR No, we're eating. We're trying to get to bed. I think that everybody shouldn't worry too much if we slipped a day, around here a little bit. Let us sleep in in the morning. (Garble) We're hanging in there. We've had a lot of (garble) come up today. You know - kind of held us back. CC Rog, Pete. I'm getting an awful lot of feedback there still. We're going to have LOS in about 1 minute. We will give you a call at Ascension and I understand that your recommendation is you'd like to sleep in tomorrow. CC And we concur. CC And we would like to make sure that we have the VTR MAIN POWER switch left on because we want to dump it and take a look at that dump - parasol deployment parasol, rather. CDR Okay, Crip, and how's that on the squeal now? That should be a little bit better. We've com­ pleted everything today, but with all the rest of the little master alarms and the few things that came up, we're running a little behind. We'll sleep in. We'll press on with the day 4 just like it is in the book and hopefully we can catch up. You know, somewhere along in there and then we'll screw our day back around to the right time. CC Rog, Pete. You're doing a fantastic job. (garble) sleep in. CDR and besides that (garble) completed (garble). PAO This is Skylab Control. We have loss of signal at Vanguard. The spacecraft is now traveling over the ocean on rev 181. We'll have acquisition of signal again at Ascension in about 3 minutes. During the conversation, one of the important points that was brought up is the pitch maneuver that has now been commanded at Vanguard. There was some question in the minds of flight controllers as to whether the crew had indicated that the craft was pitched up in their opinion or pitched down. And there was a question here whether they should do a 40 degree maneuver in one direction or the other. They did clarify that. The indication is that the crew - from the crew that there was a pitch up and we are pitched up 40 degrees, so we are now in the process of pitching down and we're also doing a roll of 15 degrees. And hope that we can get the spacecraft properly in solar inertial mode. They are not absolutely certain that 15 degrees is the right number, but �SL-II MC-117/4 Time: 23:47 CDT, 1:15:47 GET 5/27/73 it gives them a fairly wide range of latitude. They know that it's something a little over 10 and 15 should get them well within range and they have a range of about 9 degrees. They also indicated that there are figures here on - from telemetry data was that we had a 75 cubic feet per minute air flow through duct 1 in the orbital workshop. However, visual inspection there indicated that that indicator was not reading properly. And we have a 600 cubic feet per minute reading which is a proper reading for that duct with four fans operating. Some of the noise you may have noticed earlier was feedback from a speaker intercomm and they did clarify that. They reduced the sound levels there and we got good clear voice after that. No figures yet on what the temperatures are inside the orbital workshop. It's about 70 degrees reduction in temperature on the outside of the workshop, but the inside of the workshop still has it's temperatures now leveling out, all at off-scale high. As you know before we had a lot of temperatures that were below 120 degrees because of their location, but once you have air flowing that 120 degree level is now pretty well spread throughout the workshop with the exception of a couple of temperature scales. Crew is presently eating and trying to get ready for bed. They have now been given an okay to sleep in in the morning. There will be no wakeup call given, and they may be asleep promptly after this Ascension pass which is now 50 seconds away. This again puts them a little bit behind the Flight Plan, but they hope to catch up in the next couple of days. This won't be a problem now that they have the major task fulfilled. This is Skylab Control. We'll be staying live now. In 36 seconds you should hear acquisition of signal at Ascension. The Ascension pass is about a 9-minute and 48-second pass. And that's now just 27 seconds away. They should be finalizing because after that we have a period of over 40 minutes before we have acquisition of signal again at Guam. And during that period we would expect them to have gone to sleep. This is Skylab Control. CC Skylab, Houston. We're AOS over Ascen­ sion for the next 10 minutes. CDR Rog. Have you all found the Sun yet? CC We're waiting for you to tell us. CDR Did you get my (garble) on the first Skylab record? CC Negative. You faded out there.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

About a minute 50 seconds until acquisition at the Vanguard tracking ship, which is stationed off the southeast <~oast of South America. And hopefully we will have a positive statement from the crew that they have been successful in docking after the |-as^ procedure that they went through. Failing that, it looks like they go through a standoff maneuver for the evening, and regroup tomorrow for further docking attempts. We 11 wait and see what happens here over Vanguard. The Vanguard pass will last almost 8 minutes and the next station after Vanguard will be Vanguard again, an hour and 38 minutes from now. We'll stand by for the first call from sPac®~ craft communicator to the crew of Skylab II. We ve had AOS. Skylab Houston through the Vanguard. cc How do you read? CDR We got a hard dock out of it. CC Way to go. pA0 Considerable applause here on the re­ port of hard docking. ... we got a tunnel integrity CDR check in the work right now. CC Hey, way to go. Good show. CDR You can tell sim sup that we really would sure like to get some ... out of this thing after a while. CC You can bet your life I will Pete. CDR We're starting our quiescent switch configuration with the notes that you gave me some where back day before yesterday it seems like. CC Stand by for one on the quiescent check please, Pete. CC CDR Houston. We've got 6 minutes left in this pass. We do have about an hour and a half a whole rev before we get Vanguard back again. I do have just a few short notes that might help you go through the check­ list for the post docking this evening. Over. CDR Fire away. CC Okay, the first of course is get through the post docking work. And I'm not sure what of this you've done on the SEVA checklist on page L/Delta. Then go through the helmets gloves and PGA docking and stowage and that is on pages L/l-13, L/l-14 and 15 in the SEVA section. CDR Okay. �SL-II MC-60/2 Time: 22:50 CDT 14:50 GET 5/25/73 CC Okay, following that Pete, go through the presleep activity on SEVA section page L/Foxtrot. And we want to add one additional step in the presleep activity. We need to replace system Alfa LIOH canister, it's in Alfa 4 and stow the used canister back in Alfa 4. Over. CDR Okay. System A is the top system, right? CC That's affirmative Pete. CDR Okay, look we've had our problems and you've had your problems so we'll probably press on to get this thing completely configured according to the checklist that you gave us. We have eaten dinner, so whenever we get this thing done, we'll get to bed and press on first thing in the morning. I would, because of the docking like to go ahead, if we've got a good tunnel and verify all latches. It sounded to me like we got at least 10. But I would like to verify them and then we'll put the hatch back in and go to bed. Do you concur with it? CC Stand by one. CC Okay, you tell them you got anything else other than that you want to do tonight? Well he does that as far as the list. CC CDR Houston. On your question, we do concur that if you have a good hatch integrity check to verify the docking latches. Also one thing we want to be sure to catch is a fuel cell reactants valves to unlatch in a normal. And be advised that we will be going back to CMG control on the SWS. We expect you may get a little bit of movement out of it but we want to get out of TACS only. CDR Okay sir it is all yours. CC Roger that. CC Skylab Houston. CDR Go ahead Houston. CC Okay, Pete. One thing in the checklist that we were going to read you and just never had time and got in a hassle. During the quiescent panel check on panel 201, we do not want to inhibit items 9 Alfa Charlie and Delta. Over. CDR Do not inhibit 9 Alfa Charlie and Delta. 9^ That's right Pete. And where we're looking at our time line, we expect bed time will be some where around 18 hours or a little bit sooner and we think that ought to give us plenty of time to call you on this next Vanguard pass next time around, which is about an hour and a half from now, and if you don't have any objec— �SL-II MC-60/3 Time: 22:50 CDT 14:50 GET 5/25/73 tions we're going to call you at that pass and that will probably be the last AOS today. C°R Yes sir, we'll see how much we can get done in the next hour and a half. CC Okay real fine. We're about 30 sec­ onds from LOS now and we'll see you at Vanguard next time around. CDR Okay, sure glad we practiced those procedures on that probe. CC Yes sir, looking good. pAO This is Skylab Control at 15 hours ground elapsed time. We've had loss of signal out of the Vanguard tracking station. It's unlikely we will continue to pick up communications through the ARIA aircraft out east of Vanguard. The attempt at docking, hard docking was indeed successful. The crew believes that 10 of the 12 main latches did fire. They're proceeding with the tunnel pressure integrity check and going through their presleep checklist. There will be one more call in an hour and 30 minutes from now over Vanguard again. Then the crew will go to bed, and proceed with the days work tomorrow. Or going into the workshop and deploying the parasol thermal shield.

END OF TAPE SL-II MC-61/1 Time: 23:27 CDT 5/25/73 15:26 GET PAO This is Skylab Control 15 hours 26 minutes ground elapse time in the Skylab 2 mission. The Skylab space station, with a successfully docked Command Service Module is presently over the Arabian Peninsula, and an hour and 3 minutes out of Vanguard for the final com­ munications of the evening, which will consist primarily of a status report on the presleep checklist and the final goodnight of the evening. In 10 <->r 15 minutes, a press conference will be held in the Johnson Space Center news room, small briefino room. Participants being, Mr. Bill Schneider, Skylab Program Director, NASA headquarters. The two Manned Space Flight Center Skylab Program Manaaers, Kenny Kleinknecht from Johnson Space Center, and Leland Belew from Marshall Space Flight Center. They should be arriving within the next 10 minutes, and at 15:27 ground elapsed time, this is Skylab Control. END OF TAPE �SL-II MC-62/1 Time: 00:27 a.m. CDT, 16:27 GET 5/26/73 PAO This is Skylab Control at 5 hours 27 minutes 54 seconds Greenwich mean time. We can hear the horn buzzing in Mission Control to announce acquisition of signal coming up in a little under 2 minutes. We'll have acquisition of signal at Vanguard. This period of pass is approximately 10 minutes and 17 seconds, and after that there will be another opportunity at Ascension at approximately 3 minutes later. At this time it appears that we'll not use that opportunity, that they'll allow the crew to go to sleep immediately after the Vanguard pass. That's still open however, at this time. Among the instructions we passed up - in this coming pass by the CAP COM are instructions to reset the clock that they're using now - the G.E.T. or ground elapsed time clock which will be reading 17:00 hours on the next even hour. They will reset that clock to read 06:00 Greenwich mean time and from now on the mission will be conducted on Greenwich mean time. They also will give instructions to the crew to go to sleep within the next hour before 17:00 GET or 6 o'clock Greenwich mean time and their wake-up will be left open. They can wake up when­ ever they like. At any case they expect to wake up no earlier than 9 a.m. central daylight time. There will not be a wakeup call given from the ground if present plans are continued. There are two reset maneuvers being scheduled during the night and the crew will be informed about this. The first reset maneuver may take place right immediately after the Vanguard pass at Ascension. That still is - has not been computed completely and they're going to try and compute that in time and let the crew know what - the exact details that reset maneuver will be. We're going to have acquisition of signal very shortly and you can listen in for the - - This is Skylab Control. CC Skylab, Houston. We're AOS over Van­ guard for the next 11 minutes.

You were a little bit garbled there. For your information I've got a few messages for you I'd like to give if you can copy. PLT Okay, Houston. CC Roger. Fine job today, Pete. Number 1 �SL-1I MC-62/2 Time: 00:27 a.m. CDT. 16:27 GET 5/26/73 I guess - PLT Okay, this is Paul, ready to copy. CC Number one, I guess we'd like to get over for G.m.t. so your checklist tomorrow will give you some good AOS times. We'd like you to set 17:00 GET, or BET rather, to set time at 06:00 G.m.t. CC Did you copy, Paul? CC Skylab, Houston. How do you read? CC Skylab, Houston. How do you read? PLT Loud and clear now. CC Okey doke, we lost you there for awhile. Did you get the time set at 17:00 BET time will be 06:00 G.m.t.? PLT No, we didn't get any of your messages at all. Bob. As soon as you said you had messages for us, you quit. CC Okay. Let's try it again. We would like to give you - set your timer so you can go back to G.m.t. and at 17:00 elapsed time the time will be 06:00 G.m.t. PLT Okay. CC Okey dokey. And we would also like if you got time meal status for day 1. CC Okay. We would also like to insure that VHF A and B are OFF before going to sleep. PLT Okay, we had them OFF and then I noticed that I had a barber pole in a power amplifier. And I'm still not sure what games that those guys can play with it down there so we left B DUPLEX UP just to make sure he wouldn't be able to get ahold of it. That's why it's ON now. CC Okay. Okay, we're taking care of that. You can turn VHF A and B OFF. CDR Okay, Bob, and for your information the CDR ate everything. CC All right. Okey doke, Roger. PLT The PLT dipped the first spoonful of his asparagus was half wood, so I only ate about one-third of it, mostly the non-woody part. CC Rog. PLT The SPT said he ate everything. I'm going to have eaten everything else. Bob. CC Okay, very good. Thank you, Paul. CDR Okay. We have the LiOH canister changed out. We've done the quiescent switch checklist. We got a couple of questions for you. What mode would you like to leave the computer in - you want to leave it in POO and ACCEPT? And while you're answering that one - let me - we had one on whether we're supposed to use this max power down. Do you want that or not? �• I. SL-II MC-62/3 Time: 00:27 a.m. CDT, 16:27 GET 5/26/73 V CC Stand by 1. We do want the computer left in POO and ACCEPT. CDR Okay, the computer's in POO and ACCEPT and on the max power down we've stopped most of that, but there are a couple of things that we have not done. Like, do you want the E/P spectrometer off? CC Okay, Pete. They really didn't want you to do the max power down, but ...*5 PLT RCS q uad Bravo temperature indicates off=scale high, associated CAUTION. At first we didn't know if it was real or not. We ... 2 - turned those heaters off on Bravo and I assume that it's safe to turn them back on again. CC Rog. I didn't get the which C&W you had there, Paul. PLT RCS quad Bravo. CC Rog. PLT And the reason we got - the reason we got it was for temperature - that it was high at the time and now it's off=scale high. CC Rog. Copy. CC We would like to - PLT Go ahead. CC Okay. We had not planned to give you a call over the ground station, however there's several mes­ sages here that we probably ought to talk about. So we are about a minute and one half to LOS and we'll have you again at Ascension and at 16:43. I'll go ahead and hit you with a couple of things here. They would like you to back out of that MAX POWER DOWN if you could and just have the quiescent POWER DOWN. PLT Okay. I think we can sort that out. CC Okay dokey. PLT Yeah, also, I got a popped circuit breaker I want to talk about next time on panel 5. It's last one in the second row, UTILITY. We're R/L station MAIN A. CC Rog. I understand that one's popped.

Our next chance for signal will be, as the Capcom indicated, in about 33 min­ utes and 40 seconds from now at Guam. And we expect to have no communications from the spacecraft at that time unless the crew has something they would like to say to the ground. They did indicate at Vanguard that they did not expect to be asleep by 1:00 a.m. central daylight time as they were to been instructed to go to sleep. They may be up a little later, you may hear from them at Guam. We're not quite certain about that. They are expecting to go to bed as soon as possible and will get up probably get up no earlier than 9:00 a.m. central daylight time tomorrow. They will not be awakened from the ground. They will give a call to the ground from their headsets whenever they are ready to get up and go to work. This is about an hour and a half, the 9:00 a.m. mininum sleep time will make it about an hour and a half later than the flight plan that was set up premission. That's to give them time to get plenty of rest after a very hard day. This is Skylab Control at 5 hours 54 minutes and 50 seconds Greenwich mean time.

The space station at this time is on its 167th revolution on a decending node, passing over Japan. And we're about 1-1/2 minutes from acquisition of signal. This acquisition of signal may not actually indicate any sort of discussion between the crew and ground. We don't know one way or the other whether the crew will still be awake. We will, how­ ever, be getting telemetry data. And we may hear something from the crew, since they indicated they may not yet be asleep. We have 1 minute and 20 seconds to acquisition of signal.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

The crew has closed out their 14th day in space as the Skylab space station passed over the Guam tracking island - tracking station on rev 338. The crew closed out the night by getting the daily news report from Astronaut Rusty Schweickart and Hank Hartsfield. The daily medical bulletin from Dr. Charles Ross, Skylab Flight Surgeon is as follows: "The Skylab crew is in good physical condition for tomorrow's EVA. The Science Pilot mentioned his complete lack of symptoms while conducting vigorous head movements during the Ml31 protocol and the fact that none of the crew has ever experienced any motion sickness. The crew's day tomorrow begins at 6:00 a.m. Houston time. The EVA preparations will run for about 3-1/2 to 4 hours. EVA hatch opening is scheduled for 10:37 a.m. central daylight time. A four-hour EVA is planned to accomplish five - four different activities: de­ ployment of the orbital workshop solar array panel, pin ning back the S054 door in the Apollo telescope mount and changing out the S082 film magazine. The crew will be wearing Apollo-type suits during the extravehicular activity. The crew will be attached to the vehicle by means of a 60-foot long tether in which lines are provided to carry w 3 er, electri­ cal power and oxygen. During the EVA, Dr. Kerwm, an£.Commander Conrad will be hard-suited while inside the vehicle in a pressurized portion of the vehicle, Pilot P a u l Weitz will be soft-suited. He will not be wearing helmet or gloves during this exercise. He'll be in the pressurized portion of what is referred to as the structural transition section, a portion between the multiple docking adapter and the air­ lock module. Pilot Weitz will monitor systems inside the STS, ud K the (garble) PA0 i �SL-II MC-622/3 Time: 21:46 CDT, 14:02:46 GMT 6/6/73 and will also read Out procedures to the other two crew mem­ bers as they perform the EVA.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

It is now past the 4 pound per square inch level, and will rise to 5 pounds per square inch in plenty of time for a crew wakeup and they're having no problems with any of those systems so far. The TACS consumable status right now is that we have 54.5 percent of the total amount of TACS gas originally carried still in the tank. Considerable amount of TACS gas was used last night but there still remains approx­ imately 30 percent more than is required for all experiments and maneuvers throughout an eight month period. This is about 8 percent at this time - about 8 percent more than was expected in the flight plan so that there's a - there's fortunately a very large pad in this area so that we have plenty of TACS gas remaining.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

As we last saw the Skylab vehicle over Honey­ suckle the multiple docking adapter hatch was just being opened and the pilot Paul Weitz was proceeding inside as the activation of the orbital workshop was at it's very beginning. Standing by now for acquisition. CC Skylab, Houston to Hawaii for 9-1/2 minutes. SC Okay Houston, we're in the MDA and we're pretty busy. I'm working on (garble) and we're jumping around a little bit to try and clean up the command module because we got so much stuff in it. So we're moving the probe and drogue at this place. Be advised that nobody has had any trouble so far in the MDA. And be advised to tell the doctors that we did not in fact try our motion sickness pills this morning because none of us felt like we needed them. CC Roger, copy. SC Also we've got a window shade dump. And the command module is really beginning to pick up water on the inside of it I noticed. Our side hatch has got quite a bit of moisture on it and so do our windows. Just generally picking up moisture all over. But now that we've got this MDA dry air I think maybe that will help a little bit. CC Roger, copy. CC Skylab, Houston. The pitch maneuver's in work, should be about 11 degrees. SC Okay, we're going to (garble) this up up here so you guys can maneuver away to your hearts content. SC So far we've collected one screw, one nut, and one piece of red thread floating around in the MDA otherwise it's clean as a whistle. It's very nice. CC Roger, copy. PAO That's commander Pete Conrad reporting on the status of the multiple docking adapter inside. PAO Sky lab Control Houston, the Skyled) crew now inside the multiple docking adapter as the activation process has started. CC Skylab, Houston, whenever it's con­ venient we'd like to get a reading on the CL seunple. SC Okay, Houston, it was about 5 parts per million. CC Roger, copy. PAO Very little conversation with the crew at this time. Apparently preoccupied and busy as - as they start through their checklist. CC Skylab, Houston, we're about 15 seconds from LOS. We'll be picking you up at Goldstone at 57. �SL-II MC-81/2 Time: 11:44 a.m. CDT, 1:03:44 GET 5.26.73 SC Okay Houston, the MDA Doc is in the command module and the suit circuit is deactivated.

The five parts per million CO referred to in that test is well within acceptable limits. SC Roger, Houston, and we may be off the air here. We're going through umbilical connect crap and so forth. CC Roger. PAO Skylab Control, Houston, at 17 hours 2 minutes Greenwich mean time. A very little conversation with the crew as they're continuing through the checklist as the activation inside the multiple docking adapter continues. END OF TAPE �SL-II MC-83/1 Time: 12:06 p.m. CDT, 1:04:06 GET 5/26/73 PAO Skylab Control, Houston. We've just had loss of signal. Our next station to acquire will be Newfoundland. PAO As the activation of multiple docking adapter proceeds. Commander Pete Conrad presumably is spending much of his time inside the command and service module, squaring things away at that point, while Kerwin and Weitz, we would expect, are mainly preoccupied with the MTA activities. We're at 17 hours 7 minutes ground Greenwich mean time. This is Skylab Control, Houston. CC Skylab, Houston through Bermuda for 7-% minutes. SC Okay, Houston. We're hooking up umbilical for SPS PT configuration check's been made; those guys are pressing on. CC Roger, Copy.

PAO Skylab Control, Houston, at 17 hours 13 minutes Greenwich mean time. About 2 minutes 45 seconds remaining on this pass over Bermuda. The activation of multiple docking adapter continuing with Kerwin and Weitz working inside, and meanwhile. Commander Pete Conrad remain­ ing in the command and service module. We'll stand by and continue to monitor the conversation that takes place during this pass. CC Skylab, Houston, we're about 1 minute to LOS. Be seeing you at Canaries at 17. SC Roger, Houston. CC Okay, no need to acknowledge. And for your info, we're playing back the data, now on the main A undervolt. We don't think it's a big problem at this point, but we are working on a plan. We'll have them for you later this morning and we may want to change some switches and bus setups in the command module. SC Yeah, that's what we finally concluded that it wasn't just sure we got too many heaters or some - PAO Skylab Control, Houston. We've had loss of signal with Bermuda. The next station to acquire is Canary in less than one minute. We'll stand by and continue to monitor. Meanwhile, the crew aboard Skylab continuing to press on through the activation, Weitz and Kerwin, presently in the multiple docking adapter; Pete Conrad communicating with the ground through the command and service module. It appears at this point, the Skylab Crew very much on their time line for the activation. END OF TAPE �SL-II MC84/1 Time: 12:17 p.m. CDT, 1:04:17 GET 5/26/73 PAO It appears at this point the Skylab crew very much on their time line for activation. CC Skylab Houston through Canaries for about 15 minutes. SC Okay, Houston. PAO Skylab Control, Houston, at 17 hours 23 minutes Greenwich mean time. Almost no conversation with the crew during this pass. The crew most preoccupied at this point as they go through their checklist for activation. PAO Skylab Control, Houston. The EGIL flight controller reports, looking at his data that the caution warn­ ing system is working in good shape aboard the MDA. Very little conversation over the flight director's loop at this point, controllers monitoring their consoles, watching data as it appears. SC Hello. CC Hello. CC Skylab, Houston, you called? PAO We heard the callup from Pete Conrad to conjecture here. He was CC Did you call? PAO The conjecture here that he was trying to reach Weitz and Kerwin via the comm loop in the workshop. SC Say Houston, Paul wanted me to tell you he's got a primary coolant temp low. Is that to be expected? CC Standby 1. Roger that's expected. Temps are running real low down there in the MDA. SC Okay the other thing is I've gone all the way through the complete hookup and includes panel 230 CSMs with (garble). It actually got in a barber pole and none of our SIA's need to talk to one another down there. CC Roger, we copy. During one of those checkouts we heard someone say hello, hello there on the trans­ mitter, I guess. SC That was me, Jim, sitting on VOX 98. That doesn't count. CC Okay. CC Houston. SC Go ahead. CC Those SIAs aren't going to work until you get down to the page 233 there for the PLT where he puts the 8 audiocircuits in; closes those. SC Okay. PAO The SIA is the intercom system aboard the workshop. SC We figured it was some place here. �SL-II MC84/2 Time: 12:17 p.m. CDT, 1:04:17 GET 5/26/73 SC Hey, Brad, SPT is about to start ATM panel Y activation. CC Roger, and I assume that all the items previous to that have been accomplished. SC That's affirmative. PAO That report from Skylab that the Science Pilot, Joe Kerwin getting ready to start the Apollo telescope mount activation, moving well along now into the time line. We presently show a Greenwich mean time of 17 hours 32 min­ utes. And 1 minute 45 seconds until loss of signal with Ascension. CC Skylab Houston we're about a minute and a half from LOS. Next contact is Carnarvon at 01 and at Carnarvon we plan to uplink a test message to the teleprinter and when you get that you can take a look at it and tell us if it looks all right and then we'll be all set to send the pads and the rest of the uplinks. SC Okay. SL-II MC-85/1 Time: 12:33 p.m. CDT, 1:04:33 GET 5/26/73 SC How do you read from the MDA, Houston? CC Okay, we're reading you, Paul. There's a little squeal in the background. Looks like you're getting some feedback from SIAs there. SC Yeah. That was one of them. Okay. CC Hey, you sounded real good then. SC Roger. We're getting there. SC PLT's on page 2-35. CC Roger, copy. SC The CDR's finishing up primary GLY ADAPT DRYOUT, and I'll (garble) where the glycol circ reads (garble), CC Roger. Copy. PAO We just heard from Pilot Paul Weitz, speaking through the intercom aboard the workshop. SC Houston, Skylab. CC Go ahead. SC Never mind, we'll catch you later. CC Okay. Well, I've got a few seconds to LOS. PAO Skylab Control, Houston, at 17 hours 34 minutes Greenwich mean time. We've just had loss of signal on this Ascension pass. The next station to acquire will be Carnarvon, and at that time, from the Mission Control Center, we will do an initial checkout of the teleprinter system aboard Skylab. This is Skylab Control, Houston. END OF TAPE �SL-II MC86/1 Time: 12:59 p.m. CDT, 1:04:59 GET 5/26/73 PAO Skylab Control, Houston, at 1800 hours Greenwich mean time. We're standing by now for acquisition of signal over Carnarvon. We presently show the workshop in an orbit of 240.5 nautical miles by 234.2 nautical miles. During this Carnarvon pass we should have the initial check­ out of the teleprinter aboard the workshop. We'll standby now and continue to monitor any conversations as they develop. CC Skylab Houston through Carnarvon and Honeysuckle for about 10 minutes. SC Roger, Houston. How do you read? CC Roger, read you loud and clear. SC GARBLE okay the CDR has completed the command module configuration through CM02 systems config and I just completed the caution and warning checkout on the GARBLE except for 392. And we're waiting right now to go into the lock and the OWS; we're configuring for that. CC Roger and we do have things we'd like for you to set up in the command module. Are you up there now? SC Yeah, but what do you want set up in the command module? CC Okay we've looked at this heater prob­ lem; we think you've already powered down enough things that you're probably not going to get that undervolt again. However, we would like to go ahead and reconfigure the heaters. We were going to do it tonight anyhow but we'll go ahead and do it and then we'll be doubly sure that we probably won't get another undervolt, if you want to do that now. SC Okay, if you'll wait 2 seconds I'll take you down into the command module and you can tell me what to do. CC And Skylab for information we're going to command the fill valves closed according to flight plan. SC Okay and I'm down in the command module now. Could you tell me what you want done? CC Okay, panel 226; circuit breaker 02 fiftywatt heaters Main A, tow; MAIN A OPEN. SC Was that two breakers? CC That is tank 2, MAIN A. SC Are you with us Houston? CC Okay, we're in a hole right now between Carnarvon and Honeysuckle. How do you read? SC You're right it was 251 OPEN, right, MAIN A? CC Positive, tank 2 MAIN A OPEN. On 50 watt. SC That's done. �SL-II MC86/2 Time: 12:59 p.m. CDT, 1:04:59 GET 5/26/73 CC Okay on panel 2. SC Yeah. CC Okay our H2 heaters, one, OFF. 02 heaters. one, OFF. And H2 fans, one, OFF and H2 fans, two, OFF. CC Skylab how do you read me? SC (static) are you going to (GARBLE) us 1? Hello, hello. CC Skylab Houston we're in a key hole now. If you'll hang on a second or two. SC GARBLE. CC Okay, I think we're pretty good now, how about you? CC Okay. On panel 2 that was H2 heaters, one; 02 heaters, one OFF. That was two switches. SC Okay, H2 heater, one, and 02 heater, one. are OFF. CC Okay and H2 fans 1 and 2, OFF. CC CDR did you copy that last on the H2 fans? SC Where'd you disappear to that time? CC I don't know. Did you get the H2 fans OFF? SC I got the H2 fans OFF, yeah. CC Okay. That's it. SC Houston, SPT. CC Go ahead. SC Okay on the panel activation I suppose you know, but I want to be reassured that we have a power system alert light, a bat charger alert light, the battery and charger lights on CBRN 15 are ON and the - our charger the bat charge bat volts"-and reg volts talkbacks are all barberpoled. Does that jive with the power problems that you've got? cc That's affirmative. That all jives, Joe. We've lost that CBRM. sc Okay and I did not connect the CBRM an­ tenna because my assumption is we aren't going to use the I don't mean CBRN or FNRBM, the noise burst monitor. Now I'm ready to do the DAS test if you are. cc Okay standby the DAS test. We agree with the other things you said. sc Glad you can understand them. CC SPT, Houston. CC SPT, Houston. sc (Static) (Garble). cc SPT, Houston. I'm reading you broken. We would like for you to go ahead and configure for the GARBLE. We are not going to use it. We'll correct that but we would like to get it connected up. �SL-II MC86/3 Time: 12:59 p.m. CDT, 1:04:59 GET 5/26/73 SC Oh. Houston are you there? CC Roger. How do you read? SC Okay. Do you want the EP spec on or off on the panel 16? CC Roger. We want it on - ON. CC SPT, Houston. SC Houston. CC Joe we'd like to make one last attempt on that CBRN number 15. We'd like you to hit the ALL/ON switch. SC You bet. Okay we did it Hank and the lights are out at the moment. CC Hey, looks like me may have it back. SC Whoopee. CC We'll know when we get some sunlight. SC That'll be soon, right? CC We've got about 3 minutes to go. And we're about 10 seconds from LOS. We'll be seeing you at Hawaii at 23 and we plan to dump the data recorder there. SC Okay. CC And your teleprinter message should be up there now. SC We'll take a look. PAO Skylab Control Houston at 18 hours 12 minutes Greenwich mean time. The next station we'll acquire will be Hawaii in approximately 11-1/2 minutes. The later portion of that pass over Honeysuckle that was Joe Kerwin the Science Pilot who was speaking with Hank Hartsfield while he was at the Apollo telescope mount control and display panel, going through the activation process there. Eighteen hours, 13 minutes Greenwich mean time this is Skylab Control Houston. END OF TAPE �SL-II MC-87/1 Time: 1:22 p.m. CDT, 1:05:22 GET 5/26/73 CC Houston through Hawaii for 9 minutes. SC Roger, Houston. Paul's down turning on the fans in the OWS at this time. Joe is monitoring him (garble) further word for you on that in just a minute. I can see Paul is on his way back up now. CC Roger; copy. PAO Hank Hartsfield talking to Skylab through Hawaii. SC Your teleprinter message came through. It's kind of faded at the end. I hope they come through better than that. CC Do you mean that all the message wasn't there, or it just printed rather weakly at the end? SC It printed rather weakly at the end. SC Okay, Paul is out. He's closing the (garble) lock hatch at this time. CC Copy. PAO Skylab Control, Houston. That's Paul Weitz who's taken off the airlock module aft hatch. Entered the orbital workshop and appears to have activated the fans. CC Skylab, Houston. For information we're going to have to do another CMG reset here. Be coming up in a couple of minutes. SC Okay, Houston. What's the problem? We've had two ACS^malfs here in the last couple of minutes. CC ~ Well, the CMGs are saturated now (garble). SC Okay, all right. Are you ready for the DAS test yet? CC Roger. SC Okay, here comes a (garble). CC Skylab, Houston. We just want him to TACS on the control mode. SC Did you do that? CC Negative, I think it went out 20 degrees in attitude to cause it, and we'd like for you to stay off the DAS while we command the system. SC Roger. CC Skylab, Houston. We're about 1 minute from LOS. Goldstone coming up at 35. SC Roger. Do you still want us to stay off the DAS? CC Okay, you can clear the caution on your ACS malf, and we'll be standing by for Goldstone for the DAS checks. SC Okay. PAO Skylab Control, Houston. We're about a minute and a half away now from acquisition by Goldstone. END OF TAPE �SL-II MC-88/1 |Time: 1:34 p.m. CDT, 01:05:34 GET w5/26/73 CC Skylab, Houston through Goldstone for 6 minutes SC Hello. SC Hello, Houston, we hear you. CC Okay. Read you loud and clear. SC Hey, Houston; PLT. CC PLT, go ahead. SC Okay, on our very quick inspection, the OWS appears to be in good shape. It feels a little bit warm, as you might expect. From the 3 or to 5 minutes I spent in there, I would say, subjectively, it's about - it's a dry heat, I guess. It feels like 90 to a 100 degrees in the desert. Hank, I could feel heat radiating from all around me, but in the short time I was in there, I never felt un­ comfortable. I had the soft shoes and the gloves on, and nothing I touched even felt hot to me. CC Roger; copy. PA0 It's Paul Weitz giving his first - cc SPT, are you ready for those DAS tests? SC That's affirmative. sc Okay, I'm going to give you 10,000. Please acknowledge. cc SPT, you got a GO on the first one. SC Okay, here comes 20,000. cc And, Paul, did you notice the duct flows when you turned the fans on downstairs? SC If you want numbers, I didn't notice numbers. They came up to what I expected to be normal. cc Okay; copy. And you have a GO on the second one, Joe. sc Okay, and did I get this fuse thing going? Turned on eight fans down there. SC You did want only eight fans turned on for this, right? cc And, SPT, you got a GO on the third one. We wanted all twelve fans, but that's okay. SC All right. PA0 We heard Paul Weitz's first assessment of the workshop. CC SPT, you got a GO on number 1. CC SPT, GO on number 2. PA0 Meanwhile, Science Pilot, Joe Kerwin, making an initial checkout of the ATM digital computer. CC j, A GO on number 3. cc JwpjV And you have a GO on number 4. All look good. SC >• 1 Okay, thank you. And, Hank, it looks as if CPRs 15 came off the line again. Is that right? CC Roger; we concur. I think we still got :roubles with it. SC Okay. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections. For more information see, http://dublincore.org/documents/dces/.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

This is Skylab Control; 21:22 Greenwich PA0 mean time, in a gap now between Ca:rnarvon 'Track*"9 and the Guam Island Tracking Station in the western Pacific. Some discussion over Carnarvon on deployment of the parasol through the solar scientific airlock. It was mentioned that TV would be desirable through the command module window as the parasol is extended up above the workshop wall. However, the eyeball observation was prime. TV would be nice, but not to let it interfere with Kerwin's visual observation of the parasol. However, it was mentioned that after it was successfully deployed, it would be highly desirable to have a television picture. The parasol that is being carried was the brain-child of Jack Kinzler, who is Chief*°VidwIre fo? Services Division at Johnson Space Center. The hardware for the parasol, all of the telescoping tubing up, and all or the deployment mechanism adapted to the TO-27 canister we all built in the Tex Services Machine Shop.

Crew at this time making preparations for attaching the canister containing the Skylab parasol to �SL-II MC99/2 Time: 4:25 p.m. CDT, 1:08:25 GET 5/26/73 the solar airlock (scientific airlock), a rather tedious job of extending the parasol, attaching one section of rod at a time to the central core rod, the main shaft of the parasol. This main shaft is actually part of the hardware for the T027 experiment, and the parasol four diagonal ribs and central hub were simply attached to the existing experiment hardware. The outer ends of the telescoping ribs are attached by screws to the inner plate, end plate, of the canister, and as the canopy is fully extended by successive attachments of rods, much like going down in a hole with drill stem in an oil well, the four screws will be released at the end plate, allowing the ends of the rods to pass on out through the canister past the wall of the workshop and rotate 90 degrees into the four corners, taking the folded parasol canopy with it. At 21:37, up again at Goldstone in 13 minutes, this is Skylab Control.

They first have to move a water tank from the floor of the workshop up to it's permanent resting place lashed down up in the - near the dome. During this stateside pass the final discussion of the changes in the deployment procedure for the parasol will be carried out. Just one more stateside pass after this one. And then we are pretty much on the back side of the orbit which takes us through the Hawaii station and Vanguard for several REVs before we start coming back on the main part of the network.

And in all(garble) instances, ^fcthey were transient, lasting less than two seconds. However, ^Rhe first time it does give you a start. And for right now we got Bus 1 powered off on that detector. CC Okay. Would you say again the location? SC The detector in the center sleep compartment. Sleep compartment number 2. SC Roger, copy. SC Work is progressing. We've relocated the (garble) holding tank, and that went like a piece of cake, just like two thousand and in one. We've done the tripod move. We got the foil off the SAL. It is in good condition we're in a process of moving the T027 down now, while Joe hunts for the (garble) bags. CC Roger, copy. CC Skylab, Houston. Paul, we're having to manage this momentum and do maneuvers here pretty often as you know and we feel that we can't afford to have a maneuver while you're pushing this thing out. Now you can work all the way up to step 22A, but we'd kind of like to a feel for, later on in the pass here. We got about 12 more minutes. About when are you going to get to that so we can manage the momentum? SC Okay, Hank. Paul heard that and tells me that they don't have a field yet for what they are going to be at that - We'll let you know. �SL-II MC-100/2 Time: 16:48 p.m. CDT, 1:08:48 GET 5/26/73 okay, I just wanted to make you cc aware.

SC Okay, I got you on the speaker box (garble). 1 got one of my hot gloves back on again. The speaker box is about 130. We're taking the tape off the box and we're taking our time right now, and if we have any questions on the pro­ cedures, we will wait to ask you. CC Roger; copy. SC It occurs to me, the question I had was why did you want to reverse the sleeves on the SAL tripod? CC Say again, please? SC On the SAL tripod, why did you reverse the speed on it? You know, I just couldn't figure out why (garble). CC That's the screws that - the way the thing is mounted there for launch, Pete, you know, you turn those around, as part of activation. CC SPT, Houston. SC He's down in the workshop. CC Okay. SPT, just give us a call when you're ee for a minute. • SC Can I relay you. Hank? CC Negative.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

What have you got for us on the probe. I'm scared we're going to get all this stuff in and not get the probe stuff where we can get in there. CC Okay we've only got a couple items, Pete, and then Rusty has got some words for you on the probes. SC Okay. CC Okay on page 2-50 we don't want you to close the hatch channel. We'd like for that to read Don CHARCOAL MASS and then just place the hatch over the opening. SC Okay. CC And the last one is on page 2-60. On the circuit breaker configuration, panel 614, on the righthand side on duct 3 fans we want to keep all those open - the four duct 3 fan circuit breakers, we'll only use 8 fans. SC That's affirm. CC Okay and Rusty has got some words for you on the probe. CC Okay Skylab we've got 3-1/2 minutes here left in the pass for your information and let me tell you what we want on the probe. There is a general caution note - I don't know who is going to do it - but when you collapse the probe for removal be aware of the fact that it may come com­ pletely free of the drogue right at that time. SC Okay we are guessing that it will. CC Right. That's what we're guessing also. Okay when you get up in there Pete what we're interested in finding out is what is the clocking of the center shaft latch on the aft end of the probe relative to the CSM axes. If you what we're recognizing is pressing on with a normal probe removal checklist but before you do anything look at the flats on the center shaft and give us your orientation. And a good reference, by the way, is systems checklist page 2-10, gives you a look at the back end of that whole probe and you can reference the flats to that. SC Okay. Now you don't want us to put the pyro cover back on with all the handles, huh? CC Pete, we don't want it to go back on permanently at this time but if that helps to determine the orientation go ahead and do it, then take it off and then go through the rest of the probe collapsing and removal. Okay. SC Okay now CC Rusty, the picture I'm looking at has the SC cover on and I'm not sure I know what flats you're talking about? Okay, Paul, the shaft - it's a circular CC shaft with a flat on each side and what we're recommending �SL-II MC75/4 Timei 10:17 a.m. CDT, 1:02:17 GET 5/26/73 in a way is if you can draw a perpendicular through those flats and then give us the clocking of that line with respect to the command module or that diagram on 2-10, either one. SC All right. CC Okay. Now the only other things we want, when you vent the probe, is when you press the button to bleed the nitrogen out keep watching that shaft and let us know if it rotates. There is a possibility that it may rotate 30 to 40 degrees. We don't think it will but we would like to know if it does. SC Unfortunately we vented it last night. CC You vented the probe itself or the tunnel? SC No we checked the docking latched, by the way it made all 12 of them and in the process of doing that we went ahead and bled the probe. And I have the feeling that you're right. Joe said the probe was quite free in there after he bled it and I have the feeling that the whole probe is just loose in there and we do not have any capture latches. CC Roger. If you did then all we can get from you is the clocking of the shaft before you - Okay we're going to have LOS in about 15 seconds. We'll pick it up GARBLE in about 1 minute. CC Skylab Houston how do you read? END OF TAPE �SL-II MC-76/1 Times 10:30 a.m. CDT, 1:02:30 GET 5/26/73 CC Skylab, Houston. SC Go ahead. CC Okay, we got about 5-1/2 more minutes now through Bermuda, and for your info, the med conference over Madrid has been scrubbed. SC Okay, we're all healthy. And let's hear from Rusty some more on that probe. We didn't catch your last remark. CC Okay. CC All right. It sounds as though, since you've already vented the probe, that the thing we're looking for is the clocking on the center shaft, and other than that - and the caution about the probe being free, you're to press on with a normal probe removal as per the activation checklist. SC All right. And what's your opinion on if we had to undock? How we'd go about doing it? Do you think we could get the capture latches to cock? CC Okay, we're thinking about that, Pete, and we have a considerably longer procedure on verification of the probe capability, that will come later in the mission that'll answer that question specifically. One further comment on the probe removal, and that is: In your judgment you'll have to look at the back end of the probe, and if you feel that it's going to be safer removing it with the pyro cover back on, that is avoiding sharp edges, feel free to do so and let us know. SC Okay. Stand by for the clocking. Pete's looking at it. CC Roger. SC Houston, Skylab. CC Go ahead. SC Okay, the line perpendicular to the flatch on that rod is rotated 15 degrees counterclockwise from the plus-Z axis as we view it. Or from the Z-axis, I should say. CC Okay, understand. If you stand by just 15 degrees counterclockwise from the Z-axis, and that's counterclockwise looking up at the probe from down in the command module? SC That is correct. SC (garble) talking about the removal (garble) CC Roger. It has systems 2-10. Let me just verify. In other words, you're saying that the - that that line is essentially over the ratchet handle. By the extension of the line you just talked about, it's over the ratchet handle. SC That's right (garble). �SL-II MC-76/2 Time: 10:30 a.m. CDT, 1:02:30 GET 5/26/73 CC Okay, fine. Thank you. We have it, and go ahead and proceed with the removal then. SC Okay, but that now. Rusty, is the line perpendicular to the flat. CC Roger; we understand. That's the line perpendicular to the flat. Thank you. PAO Skylab Control, Houston. We've been listening to Backup Commander Rusty Schweickart chat with the crew about the probe. Presently sitting at the CAP COM' console - CC Skylab, Houston. We're about 40 seconds from LOS. We'll pick you up over Madrid at 40. SC Return at 40. SC Did you read comm check on that one? CC Roger. We heard Houston's comm check; we read you loud and clear, thank you. CC Copy. END OF TAPE �SL-II MC-77/1 Time: 10:39 a.m. CDT, 1:02:39 GET 5/26/73 CC Skylab, Houston, through Madrid for 7 minutes. SC Okay. We've got the probe out and the capture latches were not engaged. CC Roger. Understand. PAO That's CAP COM Henry Hartsfield speaking to the crew aboard Skylab on this Madrid acquisition, Paul Weitz responding to that call. SC Okay, Houston. Here's a data plate for you, 2 capture latches are out and one capture latch is stuck in. CC Roger. Copy. SC Hey, Houston. CC Go ahead. SC Another data plate on that probe. It turned out that that one was squashed and the little ear, when I kicked it, it came up. It looks, to me, like 2 of them had captured and this one, for what ever re- you can tell better on the ground than I can. It would not come up and allow the little lever to trip and lock it. It looked like something was out of sequence with the trigger on that latch. CC Roger. Copy. SC Now. We've got all three capture latches latched and if I push on the end of the probe, it will re­ lease all three capture latches, they'll all fold and then pull them all down. Now let's push that up. Now let it go, they should all lock. SC All down? Yeah. Two of them are up and the third one is stuck down and I can't answer for you, why, and so is the little center button stuck down. CC Pete, let me make sure I understand you. You went through your little sequence there, at one point you had all three capture latches out and you then tripped it again, and they went in and one of them stayed in and the button is - on the end of the probe is also staying depressed. SC With me Rusty? CC Pete, do you read? SC Yeah, go ahead. CC Yes. Did you read my summary there? Did it agree with what had happened? SC No, I didn't read your summary, let me give it to you again. When we took the probe out, 2 latches were out and they were out, but appar - (loss of comm) Push the plunger in the end of the probe - SC Capture latch released. �SL-II MC-77/2 Time: 10:39 a.m. CDT, 1:02:39 GET 5/26/73 SC Capture catch released, but left side button, it sticks in now; and the one latch, capture latch stays flush and the other two pop up. cc Okay, Pete. At one point you mentioned also, that the one that was flush, popped out when you kicked the trigger on it, is that correct? SC Well, that's what I thought, but that s what's not doing it now. SC Yes it is, too. SC I take that back, it is. Paul just did it and it came up. CC Okay. I'll tell you what, we're going to digest all that, Pete, and the boys in the backroom will be working and we'll probably come back to you at some later point. I suggest just going ahead with the time line. CC And one further question. What's the status of the pyro cover? Did you put it on, or do you still have it off? SC It's off. CC Okay, fine. We'll assume it'll stay off, then and you're going to let us know where you stow it temporarily? SC Yeah. We'll put the pyro cover in with the probe in the bag. CC Okay, thanks. CC Skylab, Houston. We're about 40 seconds from LOS. We'll pick you up again at Honeysuckle at 2.5. SC Okay. PAO Skylab Control, Houston, at 15 hours 52 minutes Greenwich mean time, our next station to acquire will be Honeysuckle.

Did you read my summary there; did it agree with what had happened? SC No, I didn't read your summary. Let me give it to you again. When we took the probe out, two latches were out. Add they were out, but apparently not locked. One was flush. Okay. Now, if we push the plunger in the end of the probe - SC Capture latch release - SC - - capture latch release left side, but it sticks in now, and the one latch, capture latch, stays flush, and the other two pop up.

CC Skylab, Houston, to Honeysuckle for about 9 minutes. CC Skylab, Houston, to Honeysuckle for 9 minutes. SC Roger, Houston. And be advised we had a MAIN A undexvolt, which sucked the voltage down to about 25 volts, and it turns out to be a heater cycle, as best we can determine it. We must have had all the heaters on at one time. If you ^ can look at your low bed rate, if you'd add that on, maybe you can come up with a better scheme for configuring these heaters for us. We just spent 10 minutes sorting that one out. CC Roger. SC And we've got about 5 minutes to go on the TDI sampling. We've gotten out sample and we're waiting the 15 minutes. CC Roger; copy. And we got a couple of things for you too. It looks like we missed a couple of checklist changes here that we should have gotten. SC Okay, hold it, and let me bring you up. We've got the secondary glycol evap dried out and the primary evap is on its way. Would you like E-memory dumped? CC Stand by. CC While we get set down here, we're - just for your information, we're going to do a CMG reset at 16:33 at about 6 minutes from now. Maximum excursion, we expect, is about 35 degrees in roll and 5 degrees each in pitch and yaw. SC Okay. Go ahead with your checklist changes. CC Okay, on page A-9, we had a comment earlier about whether you want to close the latch handle, the hatch handle, and that same comment applies there. On panel 312, we just want that to read to close the hatch. SC Okay, just close the hatch; don't lock it, is what you're saying. CC We don't - well, we had you closing in the hatch handle then laying the hatch over on the dogs. We didn't want to do that, we just want to strick that out so it just says close the hatch. SC Oh, okay. CC But don't lock the hatch. And we're ready for the E-memory dump any time. CC And the only other checklist change we got for you is on page 2-51. �SL-II MC-79/2 Time: 11:24 a.m. CDT, 01:03:24 GET 5/26/73 •t SC Who's it for? CC That's for the PLT. SC Ready. , CC Okay, there on panel 390 in the aft lock activation, we want to turn heat exchanger pans 1 ON. And the reason we're doing that, Paul, is we want to stir up the air there prior to getting a sniff sample there. SC The E-MOD's coming at you. CC Roger. SC Okay, JOB, you want the number 1 fan, or do you want them all on? CC Just the number 1. SC Okay. And we chose - like you to look at how we got that great big load on MAIN A because, as we remember at it, it just sort of kinda of took care of itself there. We were turning heaters on and off. But whatever heater cycle^ it was on, or maybe you'll see something on the data, but I 11 tell you, we had one big load on that bus for a minute. CC Roger. We'll take a look at it. CC And, for info, our attitude plan is, after we do the CMG reset here at Honeysuckle - at Hawaii, we're going to command a small pitch maneuver to get a little more power in preparation for activation. CC Roger. SC And, Pete, we got one more probe question for you here in trying to psyche this one out^ SC Go ahead. CC Okay. If the probe is not bagged yet, if you'll look, minus X along the probe and using the strut with the yellow end on it as a 12 o'clock reference, I wonder if you could give us the clocking of the capture latch which is sticking in. SC Hey, Rusty, on page 2-11 is the one you can't see on that picture. CC Okay, I've got it. And let me ask you another question. Jlave you rotated the head of the probe? Or do you think it's the same as it was for docking attempts? SC We haven't touched that, and I'm sure it's the same. It's just the way we took it out of there. Okay. Fine. So that's - looking in the CC I was saying that's something like 7 or 8 o'clock. direction, I don't know. It's in the bag now. SC Okay, fine. We've got it. Thank you. CC (Garble), Houston. SC Go ahead. CC Okay, we passed the TDI monitor check SC It's pure white. Nothing that we could with flying colors, see at all. �SL-II MC-79/3 Time: 11:24 a.m. CDT, 01:03:24 GET 5/26/73 CC Roger; copy. That's good news. SC And we're on our way to the MDA. I wish I had a poloroid picture to send down to you guys from the inside of this command module with three suits, all that gear, a drogue, a probe, and a hatch, Joe, Paul, and Pete. CC Roger. I'd like to see that myself. SC It's unbelievable. CC Okay, the CMG maneuver is coming up and we got the E-memory dump; you're cleared to do the power down now. SC Okay, going to P06.

At that point they proceeded to open the hatch to the multiple docking adapter. You heard the remarks that it was quite cold in there, in the order of 50 degrees. The lights in the multiple docking adapter apparently working. The main A undervolt, referred to as in the command service module, Conrad speculating that possibly a configuration of all the heaters on at once could have caused this. This data will be looked at on the ground. Meanwhile, as we approach Hawaii, a maneuver is planned to pitch the vehicle down 11 degrees to an attitude of 36 degrees, and this providing for a better electrical power system, which will be utilized in the course of the activation today. This pitch-down maneuver has been computed by the EGIL flight controller in the Mission Control Center, and the command will be given by the ASCO console. We're at 16 hours 37 minutes Greenwich mean time, and this is Skylab Control, Houston.

Skylab had three manned missions: Skylab 2, launched May 25, 1973, lasting 28 days, Skylab 3, launched July 28, 1973, lasting 60 days, and Skylab 4, launched November 16, 1973, lasting 84 days. Crews on Skylab conducted a variety of experiments during their missions, including experiments in human physiology, circadian rhythms, solar physics and astronomy, and material sciences. Important earth resources studies were conducting including studies on geology, hurricanes, and land and vegetation patterns. Two of the more important components for conducting research on Skylab were the Apollo Telescope Mount (ATM) and the Earth Resources Experiment Package (EREP). The ATM was a multi-spectral solar observatory, and NASA’s first full-scale manned astronomical observatory in space. The ATM yielded a significant number of images and provided useful data for understanding our sun. The EREP provided thousands of images of the Earth’s surface in visible, infrared, and microwave spectral regions. Skylab remained in orbit, unoccupied after the Skylab 4 mission, until July 11, 1973, when the space station reentered Earth’s atmosphere.

T minus 1 hour 7 minutes and counting toward lift off in the second manned mission in Skylab. At this time checks are underway on the radar beacon aboard the space vehicle. There are two of these beacons actually located in the instrument unit of the Saturn IB. They're used in conjunction with ground radars to track the velocity position and the acceleration vehicle during the power phase of flight. Up at the 320 foot level at the pad launch complex 39, the close out crew are making their final preparations. They are taking down some connector panels which connect the white room to the space craft and sealing off the boost protective cover hatch, which has now been pulled closed. We're continuing to aim for a lift off time of 7:10:50, that is 10 minutes 50 seconds after 7:00 a.m. eastern daylight time this rooming. Now T minus 1 hour 6 minutes and countinq, this is Kennedy Launch Control. END OF TAPE SL-III MC—2/1 Time: 05:10 CDT 09:10:11 GMT 7/28/73 LCC This is Skylab Launch Control. T minus 56 minutes 58 seconds and counting. Just completed was a very critical power transfer test. During this test the power is transferred from the ground source, which has been being used up to this point to conserve on the flight batteries. Transfer to those flight batteries to ensure that all systems are operating during and after that transfer. Transfer was made, the various elements of the launch team reported in that systems continued operating correctly. We switch back then to the ground source and we'll stay on that ground source down to a T minus 50 second mark in the countdown at which time we'll switch finally to the flight batteries and stay on the flight batteries from that point on. Coming up in the countdown are checks of the digital rain safety receivers aboard the space vehicle. These receivers are part of what's called the secure arrange safety systems aboard the Skylab. A range safety officer could send a destruct signal to the rockets if it became erratic or straight off course. He would do this by initiating the emergency cut off, and if necessary, the propellant dispersion command. The systems are located on each stage of the Saturn IB. The two receivers in each stage and they receive the signal from the range safety officer, and then send them through the proper channels to perform the propellant dispersion. These actions of course will be taken only if the vehicle were so erratic that it endangered land areas, and also only after the crew has been advised and has used one of the escape options that is open to them. Countdown proceeding smoothly now in the final hour. T minus 55 minutes 23 seconds and counting, this is Kennedy Launch Control. END OF TAPE �SL III MC3/1 Times 05:23 CDT 09:10:23 GMT 7/28/73 LCC This is Skylab Launch Control, T-minus 45 minutes and counting. Chief Staff Supervisor, Bill Schick advises that the swing arm, swing arm number 9, with the environmental chamber will be coming back, it's coming back now to the 12 degree or park position. Schick advises also this and other aspects of the count continue to go well. All on time or actually running somewhat ahead of schedule. The environmental chamber at the end of swing arm 9, will remain at the park position here. This is about 10 to 12 feet from the spacecraft. It could be quickly moved back to the spacecraft in an emergency. Swing arm number 9 is somewhat of a misnomer, the facilities here at complex 39 were designed for the larger Saturn V vehicle, 365-foot tall. Specially designed 127-foot pedestal adapts the smaller Saturn IB so that it does use the same upper swing arm. Actually this is the fifth of the five swing arms used for the Saturn IB, but it does continue to carry that swing arm 9 designator, which it gained back in the Saturn V program. Once the swingarm is moved back, launch escape system is armed. That's the small rocket tower that can be seen perched on top of the command module. That system could be used by the astronauts in an emergency to pull the command module free of the space vehicle. It would lift it up in an arcing path, high enough so that the parachutes could deploy and it could come down for a normal landing. That launch escape system, interestingly enough, develops a 147,000 pounds of thrust, that's about twice that developed by the Mercury Redstone rocket, which launched our first two astronauts into suborbital space. However that's a rather short duration burn of 3.2 minutes for the launch escape system. The escape system itself is 33 feet long, weighs about 8,000 pounds. Now, T minus 42 minutes 57 seconds and counting. This is Kennedy Launch Control. END OF TAPE SL-III MC-4/1 Time: 05:00 CDT 9:10:00 GMT 7/28/73 LCC This is Skylab Launch Control. T minus 34 minutes 59 seconds and counting. The closeout crew, which left the pad area just a short time ago, has now cleared that area. And the test supervisor. Chuck Henchel has announced that the KSC area is now cleared for launch. Range safety command receiver checks now have been completed and also the replenishing of the liquid oxygen and liquid hydrogen is continuing. Liquid oxygen and liquid hydrogen, the cryogenic fuels for the Saturn IB, were loaded earlier this morning. Actually completed loading at about the T minus 4 hour mark in the countdown. These are continuing to be replenished down through the countdown until we get into the terminal sequencer; the replenishing is then stopped. £t is necessary to replenish these because there is some bci ff that takes place. T minus 34 minutes 11 seconds and co ~.r.g, this is Kennedy Launch Control. END OF TAPE �SL-III MC 5/1 Time: 05:45 CDT, 09:10:45 GET 7/28/73 LCC This is Skylab Launch Control, we are T minus 23 minutes 48 seconds and counting toward the lift off of the second manned mission in the Skylab program. Count continuing to go smoothly here at Launch Complex 39. Preflight command checks with the Mission Control Center in Houston have just been completed. These are the checks of the systems which are used to remotely command various functions in the vehicle. Checkout of radar beacon number 1 has been completed. Checkout of radar beacon number 2 underway as all continues to go well. Science pilot Owen Garriott at this time is completing some checks of the service module reaction control system. He's armed that system which in a sense means that he has opened valves allowing the hypergolic fuels to flow down to the engine area. Hypergolic fuels are ones that ignite on contact. In this case, for the service module reaction control system, these fuels are monomethyl hydrazine and nitrogen tetrocide. The system has been pressurized, Garriott is now reading off the different temperatures and pressures and the fuel quantities. Hypergolic fuels are actually loaded aboard the service module well before the countdown began. Service module reaction control system provides stabalization and control of the spacecraft during Earth orbit and docking. It can also be used for minor course changes or the backup system for deorbiting the spacecraft. We're continuing to look for 7:10 lift-off. Actually to be more accurate 07:10:50, 50 seconds after 07:10. We have a window which extends to 07:19:27, that's a.m. eastern daylight time. Weather continues to look good. The sun is about to come here at Kennedy Space Center, it's coming up through some cloud cover, we expect some of that to blow off and at lift-off time, approximately 22 minutes from now, we'll be looking for some scattered clouds, surface winds at 6 knots, temperature is approximately 76 degrees farenheit, and a visibility of about 8 miles. There is a possibility of some ground fog but 8 miles visibility should be good in most areas. T minus 21 minutes 44 seconds and counting, this is Kennedy Launch Control. END OF TAPE �SL-III MC 6/1 Times 05:53 CDT 09:10:53 GMT 7/28/73 MCC This is Skylab Launch Control. T minus 15 minutes and we're in a planned brief hold at this time. This is actually a clock adjustment hold. It's to insured that we are lifting off at the proper time to get us in the best trajectory toward the orbiting laboratory. We'll resume our countdown at 6:55:50 seconds. That's 6:55 am and 50 seconds. Chief Test Supervisor Bill Schick just reported to us before going into the hold that all systems are in good shapem the countdown has been running very smoothly. As we lift off at 7:50 this morning the orbiting Skylab will be some 300 nautical miles South of Newfoundland. Predicted lift-off time 7:10:50 at this time. The orbiting lab of course was launched back on May 14. Flight controllers out at Houston report that all systems aboard there are in good shape and ready for the second crew to move in and set up housekeeping. That crew aboard the command service module this morning eager to get there. When the count resumes at the T minus 15 minutes mark the ?Launch operations manager Paul Donnelley here in the firing room he has the abort advisory responsibility up to the point when the space vehicle clears the tower. He'll make some communi­ cation checks with the astronauts on the special astro launch circuit. This is a circuit on which the spacecraft test conductor, the astronaut communicator Bob Crippen here in the firing room and Donnelly use with the astronauts during the final 4 minutes of launch. This is essentially to isolate them from any other discussions which might be going on in the operational intercom system here in the firing room which link together the various members of the launch team. Also as the count resumes spacecraft will be going to full internal power. Up to this point it has been powered by the fuel cells aboard the space­ craft but also it has had a ground source fed to it as a backup. We're about to resume the count. MARK. T minus 15 minutes and counting now. Preparations under way at this time now to chill the systems in the second stage which will be receiving the very cold liquid hydrogen after first stage burnout and as the second stage ignites. T minus 14 minutes 45 seconds and counting. This is Kenneday Launch Control. END OF TAPE �SL-III MC-7/1 Time: 06:01 CDT 01:11:01 GMT 7/28/73 LCC This is Skylab Launch Control. T minus 8 minutes 59 seconds and counting. Bean, Garriott and Lousma are now finishing up their checks inside the spacecraft. Final launch vehicle checks also being made now before going on the automatic sequencer. There is not an ignition switch or button for the Saturn launches either the Saturn 5 or the Saturn IB. An automatic sequencer takes over the count at T minus 3 minutes and 7 seconds. And that sequencer then initiates all action from that time, including the ignition. There are some 91 cameras out at the pad that will cover the action at ignition detailing the sequence of events for engineers to study after the launch. A number of visitors here at Kennedy Space Center have jammed the entire space center. 35000 guests have taken all available space on the space center and this does not include thousands of people who are lining the highways nearby. T minus 8 minutes 8 seconds and counting. This is Kennedy Launch Control.

At this time various elements of the Skylab team reporting in to the test supervisor with their go or no go status. This team includes the mission controllers in Houston. The Program Director who is watching from here at Kennedy Space Center for this launch. The Air Force Eastern test range who will perform tracking during the powered phase of the flight, and of course the launch team here in the firing room, all reporting in at this time. Houston flight just reported in that they are go for the start of the automatic sequencer. The Program Director William Schneider also reports we're go for launch. Swing arm number 9, that's the access arm that reaches across the launch tower to the spacecraft, will be swinging back to the full retract position just a few moments from now. Up to this point it's been in a park position for about the last 40 minutes in a stand by park position about 10 to 15 feet from the spacecraft. T minus 5 minutes. And sswing arm number 9 coming back now. It will swing back 180 degrees, and a fully park position beside the launch tower and it will remain there now through launch. Safety and test support now reporting to the test supervisor Chuck Henschel that we are go for launch. The range also says we are go for launch. Launch Operations Manager, Paul Donnelly has given his go and Walter Kapryan, Director of Launch Operations gives us a go for launch.

T minus 3 yes, 3 minutes 30 seconds and continuing to count. Launch Vehicle Test Conductor Norm Carlson has reported to the Test Supervisor that the launch vehicle is cleared for launch. Essentially what he is saying is the launch vehicle is ready to go on the automatic sequencer. The automatic sequencer comes into play at T minus 3 minutes 7 seconds in the count­ down. Launch sequence has started now we passed the three minutes 7 seconds mark and we're on the automatic sequencer. Liquid oxygen and liquid hydrogen have been being replenished up to this point. That replenish now will be terminated, the vents will be closed and the fuel tanks will be pressurized. This replenish has been necessary since these are cryogenic or extremely cold fuels which do boil off. They were fueled. Fueling was completely about 5 hours before launch and it's necessary to continue to replenish them on down through the final portion of the countdown. Various elements of the launch team now reporting in. All coming in on a go condition. T minus 2 minutes 20 seconds and continuing to count. Here in the firing room we are having what's called operational silence. The men have reported in that they're go. There will be no further reporting in now except when they see a problem. If they saw a problem they could report in. Could request an override to this automatic sequencer and stop the count. Bob Crippen the Astronaut Communicator here in the firing room is reporting the countdown clock times to the crew. Chuck Henschel the test supervisor reporting - END OF TAPE �SL-III MC-10/1 Time: 06:08 CST 09:11:08 GMT 7/28/73 LCC - - supervisor reporting the countdown clock times here to the firing room team.
