CC: Okay. I'm on 1-13 of the Activation Checklist.
CC: Okay, Jim. After the addition on that page which reads, "Circuit breaker 11, ECS CABIN FAN, closed," add: "Circuit bres_ker 11, EPS: DC BUS VOLT, closed."
CC: Okay; copy: "CB 11, EPS: DC BUS VOLT, closed."
CC: Okay, Jim. That's it fr_n down here for a while.
CDR: Houston, 15_ Go.
CC: Roger; Dave. The next time one of you floats past the LM/CM DELTA-P gage, could you get a read-out for us, please?
CC: Roger; no hurry. 35/5 Tape
CDR: 2.0.
CC: Copy 2.0. Thank you.
CC: Apollo 15, go to POO and ACCEPT, please, for a clock-sync update.
CDR: Roger. P00 and ACCEPT.
CC: Your computer, Dave.
CC: Dave, is that time okay?
CDR: Roger. We're within about - 1200 to the mission timer.
CC: Sounds pretty good to me.
CC: That's the old NOUN 65 trick.
CDR: Roger. I guess I should have said 12 mini- seconds.
CC: Yes. Mercy_ yes.
CC: 15, Houston. Requesting BLOCK on the UP TM.
CDR: Roger. Thamk you.
CMP: Hello, Houston, 15.
CC: Hello, 15, this is Houston.
CMP: Hey, Joe, I JUst did a DELTA-V and null bias check if you want to copy ...
CMP: Okay, the DELTA-V check was - test was satisfactory. It was a residual minus 21.0 in 10 seconds, and the null bias was .8 feet in 100 seconds.
CC: Okay, Al. We copy. Thank you.
CC: And, Al, this is Houston.
CC: Roger. Will You be starting into your lunch break now?
CMP: Affirmative.
CC: Okay. That sounds like a good idea.
CC: 15, Houston. If anyone by chance floats past the LM/CM DELTA-P gage, we'd like another read-out.
CMP: Okay, Joe. We'11 get that for you,
CC: Roger, Al. Would you tell Jim, please, that I've got a - a change Echo to his IR Activation Check- list, when he finishes with lunch and wants to copy it down. No hurry on it, but I don't want to for- get it.
CMP: Okay, Joe. I'11 tell him.
CC: Roger. The next time somebody goes down into the kitchen to mix up some food, could you read the DELTA-P gage for us, please.
CDR: Roger. It's 1.9.
CC: Copy 1.9. Thank you.
CC: Roger, Dave. As luck would have it, we lost our comm just as we got the DELTA-P number from you. We copied 1.9. Verify that for us, please. And, also, would you make sure that the valve is still in the VENT position.
CDR: Roger. I checked that. It's LM TUNNEL VENT and it's, well - 1.9 to 2 - pretty close. position.
CC: 15, this is Houston. We have a further question about the LM TUNNEL VENT valve.
CDR: Okay; go ahead, Joe.
CC: Roger, Dave. We should have had a much greater drop in pressure - during the - the time between these two readings. We want to confirm that you went to the DELTA-P position to read the meter this second time. Over.
CDR: Oh, no. I thought you Just wanted the reading in the LM position.
CC: No, sir. Apparently we have to go over to DELTA-P, get a reading, and then go - return to the VENT position.
CDR: Yes, that's absolutely correct, Joe. Thank you. We '11 do that.
CDR: Okay. In the LM/CM DELTA-P - it's 2.9, and then back to LM TUNNEL VENT is 3.5.
CC: Okay, Dave. We copy that. Sounds so much better.
CDR: Yes, it sure does, doesn't it.
CC: Roger, 15; go ahead.
LMP: Joe, I understand you have another change to the Activation Checklist.
CC: Roger, Jim, I had to change Echo for you. I'm up to change Foxtrot already, if you're ready to copy.
LMP: I'm ready to copy, Joe.
CC: Okay. Nothing very profound here. It - it has to do with the LM housekeeping cleaning procedures I read to you at 57 plus 45. And the procedures which I read were basically a cleaning of vacuum cabin fan filter. And it involved unsnapping a netting around the cabin fan filter, running the vacuum cleaner over it, and finally replacing that netting. And we've had second thoughts about that entire procedure down here - mainly, because the netting is in too cramped an area to get to com- fortably - it takes a long time to take the netting off and replace it, and the - the procedure is, actually, not too effective, anyway. So - we want you to delete this entire step, and I have two more to add instead of this particular step at 57 plus 45. Am I clear so far?
LMP: Ah, yes, you're clear so far. Do you still want us to turn the cabin fan on?
CC: Roger, Jim. In fact, the procedure now reads like this. Before you begin the LM Activation Checklist and you're entering the LM, we want you to vacuum all the LM accessible areas such as Velcro, places like that, where dirt and particularly glass parti- cles have accumulated. Then, when you've cleaned it to your satisfaction, tape the vacuum cleaner to the engine cover. Let it run while you'r_ do- ing the rest of the housekeeping activities. Over.
LMP: Okay; I understand, Joe.
CC: Okay, Jim. And then, finally when you're through with the housekeeping activities, clean the vacuum cleaner inlet screen with sticky tape. We think you'11 probably find there are glass particles there which you can remove conveniently with the sticky tape.
LMP: Okay; I copy.
CC: Okay, Jim. That's all I had for you, really.
LMP: Joe, this is 15 again.
LMP: Roger. Did you confirm that you still want us to turn the cabin fan on?
CC: That's correct. We - we confirm that. We want the cabin fan turned on. glass on the cabin fan filter, then I suppose we should try to get down there with tape and clean it off.
CC: Roger, Jim. That's right. It Just - we do not now want you to unsnap the netting around that cabin fan filter, in spite of what we told you earlier. It still might be possible to clean that area with sticky tape - without unsnapping the net- _ ting, though.
LMP: Okay; I understand.
CC: Basically, - I know you understand. We - we just want as much of the glass in the LM cleaned up as you can find.
LMP: Okay. I think we cleaned it up pretty well yester- day, but we '11 do it again.
CC: Roger. Just look around. It may not take much at all to take it.
CDR: Houston. Apol -
CDR: Yes, Houston. Go ahead.
CC: I was informed that you called, did you call?
CDR: Roger. We were wondering if you've got the HIGH GAIN angles for us - -
CDR: Yes, we called you.
CDR: Okay. We are ready to cycle the cameras, now, if you've got some HIGH GAIN angles for us.
CC: Stand by on the HIGH GAIN angles.
CC: Roger, 15. Your HIGH GAIN angles are PITCH, minus 75; YAW, plus 36.
CDR: Okay; understand. PITCH, minus 75; and YAW, plus 346 [sic].
CC: Plus 36. Affirmative.
CDR: Okay; tell you what, Houston, we'11 go back to 50 degrees roll and pick up the UV for you ... up here.
CC: 15, this is Houston - -
CDR: And, Houston, 15. Did you copy the P527
CC: Roger. We got your torquing angles. Thank you. And they say down here that you don't need to roll at the present time. We'd Just as soon save the propellant.
CDR: Well, we'11 pick it up at the 50-degree mark, when we come around.
CC: Okay; that'11 be fine.
LMP: Okay, Houston. We've got you on the high gain now, and we'11 check our circuit breakers, be ready to cycle the cameras when you're ready.
CC: We copy, 15.
CDR: Okay, Houston; 15. If you've got telemetry, we'11 cycle the film on your cue.
CC: Roger. Stand by, 15.
CC: 15, this is Houston. Before we cycle the cameras, can we need to stop PTC. You either do that im- mediately - or else go through the - go through the 50-degree roll and use the angles that are in your Flight Plan. That's your choice.
CDR: Oh, we'11 Just press on to 50 degrees, and stop there. We thought you could pick it up on the way around.
CC: That will be fine. Thank you.
CDR: Okay. I'm taking a look at our attitude for the UV photos. We see we need a ROLL of 153, and your update today gave us a roll of 050 degrees. And, it seems like we probably ought to stop the roll at 153, and Just skip that 050-degree atti- __ tude so we can save the maneuver.
CC: 15. The high gain won't be available to us at the angle 153.
CDR: And, Houston, 15. For future reference, I - I guess we are to understand that you cannot do the camera cycling while we're in PTC, even though you have high gain. Is that correct?
CC: Dave, there are pros and cons to that. We could do it if we finessed it Just right. But since it's difficult, and we have to stop rolling anyhow, it's better to stop the roll this time.
CDR: Well, that - that's true. We were Just trying to save you a maneuver. We got to stop the roll and start the roll again to get back to another spot. But, we '11 go that way.
CDR: Okay, Houston; Apollo 15. Standing by for the MAP and PAN CAMERA, ON, on your cue.
CC: Roger, 15. We have a good high gain lock on, and we're GO for the cycling of the cameras.
CDR: Roger, Houston. We're standing by for your cue to cycle the map and pan cameras.
CC: Roger. We are ready to cycle the man and pan - the - the pan and mapping cameras. Go ahead.
CDR: Okay. The man [sic] and pap [sic] cameras are coming up now.
CDR: Houston, Apollo 15. That completes the man [sic] and pap [sic] camera operation. And if you're through, we'11 secure the high gain and maneuver to the UV attitude.
CC: Okay. You're GO to maneuver to the UV photo at - attitude.
CDR: Okay. On the way. Thank you.
CC: We wonder if you can give us an estimate of how long it takes between removing the Lexan shade and getting the cardboard shade back into the window, when you go into the UV experiment. We need something rough to, say, plus or minus 30 seconds.
CDR: Karl, this is 15. Looks llke you Just barely got started when we - when we lost the S-band. How about saying that over again, please.
CC: Roger. We'd like to have an estimate of how much time it takes between removal of the Lexan shade, and installation of the cardboard shade, when you go into the UV experiment. Something rough to, say, plus or minus 30 seconds.
CDR: Karl, we've kept the cardboard in the window up to now. We've had no need to put in the Lexan, so we can't give you the ... right now.
CDR: But we will - the next time we change it, keep it in mind, and we'11 give you the ...
CC: Okay. We'd like to have an estimate on that, when you get a chance.
CDR: Okay, Karl. We're through with the UV photos, and the window number 5 is still clear.
CC: Thank you very much for the report.
CC: 15, this isHouston. You can terminate the charge - charging of battery Bravo. And, when you have a moment, we'd like to get a readout on the I_M/CM DELTA-P. And, in about 20 seconds, we're going to have a handover and a loss of corem for i minute.
CDR: Okay, Karl. We're terminating battery B charge now.
CC: 15, we'd like to have OMNI Charlie, please.
CC: 15, this is Houston. We'd like to have OMNI Charlie, please.
CC: 15, this is Houston. Are you reading us?
CDR: Yes; Roger, Houston. We're 5 by. Our LM/CM DELTA-P is off-scale high. And I wonder if you're happy with the depressured LM, and may we get on with repressurizing it and go to our housekeeping?
CC: Roger, 15. You have a GO to proceed.
CC: And, Al, can you tell us how the - the shade on window 5 - how the hole is being blocked. Do you have the Lexan over it, or do you have the camera in there?
CMP: Okay. We have the cardboard on it and the metal shade behind that.
CMP: We've been keeping the metal shade on that window to try _nd keep the temperature in the cabin down b_.t. a little When the Sun is coming in the windows, i$ warms things up pretty well.
CC: 15, this is Houston. If you would go to a 5-degree med-dead band they say down here we might save a little bit of propellant.
CC: 15, this is Houston. If you got a little cry - CRYO PRESS light up there - we see that down here, and that's expected at the moment.
CMP: Roger, Houston. Falcon's all set up for data, and want to know if you're getting it.
CC: Roger. We're getting data from Falcon.
CMP: Roger. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CMP: Okay. If you'11 let me know - when you've gotten enough data from Falcon, then I can tell Jim to fire that down.
CC: 15, this is Houston. The batteries in the SHe all look to be in excellent shape, and we're ready to secure the instrumentation. They can go ahead to page 1-18.
LMP: Roger. Understand, Houston. We go on to 1-18. Thank you, sir.
CC: 15, Houston. Is it possible to get the ED BAT readings?
LMP: Stand by l, Houston.
LMP: Houston, the ED batteries are reading 37 on both.
CC: 15, this is Houston. Would you please put 02 HEATERS l, 2, and 3 all to AUTO?
LMP: Roger, Karl. 02 HEATERS 1, 2, and 3, all AUTO.
CMP: Roger, Karl. Looks like the - the LM checkout's coming along pretty good. We've checked out all the batteries now. When do you want us to start in the PTC?
CC: Roger, Al. We - we want to get a few minutes, about 5 minutes of SIM bay data there at - it's 15:45 in your Flight Plan, and then we're - then we can go into PTC.
CMP: Okay, Karl. If you're ready, we'11 give you the SIM bay data, now.
CC: Hang on just 1 or 2 minutes. We're not completely set up down here.
CC: Al, we're ready for the SIM bay data.
CMP: Okay, Karl. Coming your way.
CC: 15, Houston. We'd like to have you turn 02 HEATERS i and 2 OFF at this time and leave number 3 AUTO. on
CMP: Okay, Houston. Coming OFF with 1 and 2 and leaving 3 in AUTO.
CC: 15, this is Houston. We have enough SIM bay data and you can terminate that procedure. And we're ready, then, to go into PTC, and we would like - Alfa and Delta for damping and Bravo and Delta for spinup.
CMP: Okay, Houston 15. Understand you've got enough SIM bay data so we'11 turn it off. Going into PTC and using Alfa and Delta for damping and Bravo and Delta for spinup.
CC: 15, this is Houston. How are we coming along on closing up the LM?
CMP: Houston, 15. We're coming along, taking our time doing it, Karl, while we're getting going on PTC.
UNKNOWN: And we'11 be a few more minutes - stabilizing the rates here for the PTC until we get all the dumps done.
CC: Roger. And be advised that we're prepared to read up a fairly extensive revision to the SPS burns, and we'd like for you guys to - let us know when you're ready to - discuss it and copy it.
CMP: Okay, Karl. It'11 be a while yet.
CMP: Okay, Karl. How do the rates look to you now?
CC: Okay. They - Okay, Al; they look good to us, and you can go ahead and spin her up.
CC: 15. We'd like to have OMNI Bravo, please.
CMP: OMNI Bravo. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: Al, this is Houston. Could we have HIGH GAIN, MANUAL and WIDE?
CC: We don't want to bring it up. We simply want to select MANUAL and WIDE.
LMP: Okay; you have it.
CMP: Houston, Apollo 15.
CMP: Roger. We're all up on the comm and ready to talk about the SPS. volved in hashing all of this out, and I'd like to have him read it up to you and argue with you about it.
CDR: I'11 do that, Go ahead, Richard.
MCC: Hello, Dave. No argument; what are you doing way out there?
CDR: Oh, we're Just sort of checking out the old LM - -
CDR: - taking a look at the pretty scenery.
MCC: Okay. Listen, we've been, as you might guess, been talking a great deal about P40 procedures, and we do have some changes to talk to you about and if you've got your G&N Dictionary [sic] handy and page 5-1 where the P40 thrusting goes, I'd like to go ahead and go through it and discuss it with you.
CDR: Okay, let us pull it out, Dick.
CDR: Okay. We've got 5-1 out; go.
MCC: Okay, Dave. Right below the "Verify the SIM powerdown" line there, I'd like for you to insert two lines. "Circuit breakers, BPS PILOT VALVES, two of them, open, and that should be a "Verify."
CDR: Okay. Should be "SPS PILOT VALVES, two, open; verify."
MCC: And then the next line would be "Circuit breakers EPS, GROUP 5, two of them, closed; verify."
CDR: Okay. "CB EPS, GROUP 5, two, closed; verify."
MCC: Okay. Right there in the same column, underneath "Test caution and warning lamps," insert "EMS FUNCTION, OFF; verify."
CDR: Okay. Beneath "Test caution and warning lamps," "EMS FUNCTION, OFF; verify."
MCC: Roger. Then the next line would be "Circuit breakers EM_ main A and B, two of them, closed."
CDR: Okay. "CB _S A and B, both, closed."
MCC: Okay, Dave. That'11 finish up that page. The next comment's on page 5-2, where it starts in with a TVC check and prep, second line, "Circuit breakers SPS 10, vice 12, close."
CDR: Okay; understand. "CB SPs 10, vice 12, closed," and those are the two PILOT VALVES?
MCC: That's affirmative. Okay. Page 5-3 at the 2-minute point - 58 with 2 minutes in parenthe- ses - like for you to scratch the line that says "DELTA-V THRUST A paren B, NORMAL" and substitute "Circuit breaker SPS PILOT VALVES MAIN B, closed." _
CDR: Okay. "CB BPS PILOT VALVE MAIN B, closed," instead of the "DELTA-V THRUST A and B to NORMAL."
MCC: We got an OMNI - -
CDR: Okay. Go ahead; we got it.
MCC: - Okay; we got an OMNI switch; Just hang on. Okay, Dave. The - the next one is on page 5-4 below the line that says "PRO at TFI greater than 0 seconds," insert "DELTA-V THRUST A and B, two of them, to NORMAL," and we'11 come back and discuss that in a minute.
MCC: Okay, Dave. Did you get that? DELTA-V THRUST A and B, two of them, to NORMAL right after the PRO at the flashing 99?
CDR: No, we - we lost you on the comm there, Dick. At minus 2 minutes and we verified we scratched the DELTA-V THRUST A or B, to NORMAL, and substituted CB SPS PILOT VALVE MAIN B, closed. That's the last we heard from you.
MCC: Okay. On page 5-4, I was Just talking about that line where you get the flashing 99, and the line Under that line, insert "DELTA-V THRUST A and B, two of them_ to NORMAL, and I'm sure we'11 want to discuss this in a little bit.
CDR: Yes, it sounds like it. Okay. After "Auto igni- tion, PRO at TFI greater than 7 - greater than 0 seconds," insert "DELTA-V THRUST" - Did you mean A or B or do you mean A and B? NORMAL?
MCC: I mean - I mean at this time A and B, and we'11 talk about different burns on this very subject a little la_er.
CDR: Okay. A an--:_ B, NORMAL.
MCC: Okay. Down in the next paragraph where it's got the 06 40 and the emergency procedures for the flash- ing 97 40 for the SPS thrust fail, scratch the line that re_ds "DELTA-V THRUST B paren A, NORMAL," and insert "Circuit breaker SPSPILOT VALVE MAIN A, closed."
CDR: Okay. On the flashing 97, scratch "DELTA-V THRUST B paren A, NORMAL," and insert "CB SPS PILOT VALVE B, closed."
MCC: That was SPS PILOT VALVE MAIN A, closed.
MCC: That was MAIN A, closed, Dave.
CDR: Okay. MAIN - Roger. Sorry about that, MAIN A, closed; right. an
MCC: Okay. What we're saying - if you don't get igni- tion on B, we want you to go ahead and use A.
MCC: Okay. The next change is at 3 seconds. Scratch the line that says "DELTA-V THRUST B parch A, NORMAL," and insert "Circuit breaker SPS PILOT VALVE MAIN A, closed."
CDR: Okay. At 3 seconds, scratch "DELTA-V THRUST B, A, NORMAL," and insert "CBS - CB SPS PILOT VALVE MAIN A, closed."
MCC: Okay. _n the bottom of the page, this is applica- ble to LOI only. And at 6 minutes into the burn, we want the line "Circuit breakers SPS PILOT VALVE MAIN A, open."
CDR: Okay. At 6 minutes into the burn, "SPS PILOT VALVE MAIN A, open."
MCC: Okay. And then a note there for Jim. At that point, we do - we no longer want any PUGS manipu- lation for fuel valves.
CDR: Okay; understand. No PUGS after 6 minutes.
MCC: Okay. We'11 talk about the reason for that in a second. I've got one more line in your Pd0 check- list, and then we can discuss some things. On page 5-5, it's in the cleanup column there, about halfway - no, almost to the PRO underneath the line that reads "Circuit breakers SPS PITCH i and YAW l, open," insert "Circuit breakers SPS PILOT VALVE MAIN B, open."
CDR: Okay. Beneath "CB SPS PITCH l, YAW l, open," insert "CB SPS PILOT VALVE MAIN B, open."
MCC: Okay. That cleans up the - the checklist items. Take the easy one first. And the reason we want to - to secure bank A during the LOI burn at 6 minutes is so we can get a handle on the single bank performance, and we anticipate making all of the other burns with the good bank, bank B, with the exception of TEI.
CDR: Okay; that makes sense.
MCC: Okay. And I guess the - the other things we might talk about Just - Just briefly is that the proce- dures that we Just gave to you are for LOI. For midcourse 4 and DOI, we'11 use the same procedures, but we'11 do it on bank B only, single bank burn; we'11 use the good bank. And we won't do anything with the PILOT VALVE for MAIN A or the DELTA-V THRUST A. We'11 Just go ahead and do these pro- cedures, but not use bank A at all.
CDR: Okay; understand. We'11 use dual bank for LOI and TEI, and all other burns will be on bank B only, with no manipulation of the DELTA-V THRUST A switch.
UNKNOWN: Okay. And after we do our LOI and DOI, we should have some real good visibility into bank B; and for Al's planning, when he's up there by himself for the CIRC and plane change burns, we'11 use normal procedures. The old procedures DELTA-V THRUST B, NORM3YL, at _. minus 2 minutes, with the exception lg that we will make those burns single bank, and we will not a_tempt to use bank A.
CDR: Oh, okay. Well, then, we - we've got three groups and when Al soloes, he's going to use single bank B Just like he's always done with the circuit breakers with CB SPS PILOT VALVE B in at the be- ginning of the procedures. Is that right?
MCC: That's correct. And for TEI, the only change we'11 probably make is the procedure we Just passed. We'11 probably let bank A - we'11 probably leave bank A in the burn until we get down to about 5 seconds to _o, and the reason for this - if something happens to the banks then, we're within our RCS capability for midcourses.
CDR: Okay, I guess - Okay; we - we can press on here, but we'11 probably talk it over with you before each burn anyway, too.
CC: Yes, I'm sure we will. And I guess the thing to talk about now is our reasoning, our thought processes on having you proceed at 5 seconds, and then having A1 throw on both the DELTA-V THRUST switches right after that. And let me go through it, and let you think about it then. The reason we want to do that now, even though we do have a great deal of confidence in bank B, but the SPS ENGINE THRUST light - we have no visibility into that system as long as that light is on. And, if for some reason, since we do have this suspect system here in A, we don't want to take the chance with B. And when that thing fires off, we want you to be on a good guidance. You won't have to do anything as far as your guidance is burn, concerned. You can continue the and press -- on even though it - it may have ignited prematurely. It does require procedure change, and I think you and Al think about how you might handle this, and - and come back to us. But those are the reasons we did want to turn either DELTA-V THRUST on earlier than the point where you'11 get good G&N- guided burns.
CDR: Okay. That sounds like you've been doing some good deep thinking on it all. That fits pretty well, Dick.
MCC: Okay, Dave. We'11 let you guys think about those - Hang on.
MCC: 15, Houston. !
CDR: Okay. We got signal strength back, also, Dick. Go ahead.
UNKNOWN: Okay, Dave. I guess we might talk about MCC 4 Just a little bit. We haven'% really gone into this - -
UNKNOWN: - - too deeply.
UNKNOWN: We haven't gone into MCC 4 too deeply yet. Right now, it looks like it's a DELTA-V of about oh, 4.2, and our intentions are at this moment to m_ke that single bank burn with bank Bravo. And if something happens there, we're looking at possibly finishing that up with - with RCS. But we're not definite on that, and Just wanted you to kind of have a feel for it.
CDR: Okay; that makes sense. I guess we've got one point here, and looking at the postignition sequence on the L0I burn. In order to monitor start tran- sients and retain Al's capability to take over in case we have a gimbal hardover at start or something circuit breaker, the SPS PILOT VALVE MAIN A, closed, as soon as we get ignition. And then that would enable A1 to get back over in the the in case he's got a problem there. How about that?
UNKNOWN: Okay. We did discuss that a little bit down here about that time. We felt that we'd like to have the - the engines stable out - stabilize out to guidance sad the engine on bank B before he even goes over and tries to get that PILOT VALVE cir- cuit breaker in. That will give us visibility on - on the DME dump on how bank B is performing.
CDR: Okay, then. Why don't we move it down some time past 3 seconds, a little later. How would that fit you?
MCC: Well, we discussed that one, too, and 5 seconds was used. What would you like? sounds than
CDR: Well, 5 seconds a tad better 3, and it gives - gives us a chance to get stable in here, and gives A1 a chance to take a look at what kind of start transients we've got.
MCC: Okay. Dave, I guess our discussion around here - We had proposed 5 at one time, and it was a change to your normal procedures of putting the other _ bank on, so I guess it's really your choice in this regard; 5 seconds is Just as good as 3.
CDR: Yes, okay. Well, (laughter) A1 made the point that it's all changed anyway, because normally I bring on hank - the second bank in 3 seconds, and he doesn't have to worry about it. He's concentrating on the start transients and everything. So it's change a complete at any rate, and I think it might be a tad better to go to the 5 seconds with A1 on the circuit breaker.
MCC: Okay; that sounds good to us. Yes, Dave; the point's being made that it can be even longer than that, if you really feel like you need it.
CDR: Okay. Well, we'11 shoot for 5 seconds and if A1 feels uncomfortable about the start transients and wants to hang on to the T-handle, I think that ought to be his option.
MCC: I couldn't agree more.
MCC: Okay. Karl's got some things here, I guess, on the LEB lighting and stuff, and my question to A1 is how he w_ts to handle the timing if he doesn't have that LEB timer for P24s and those good things that he's doing.
CDR: He's thinking, Just a minute.
MCC: Okay, We don't need an answer now. Karl's got some things on - on that. We can use this as a discussion period, I guess.
MCC: Dave, I'm going to go get dinner. We'11 talk to you later.
CDR: Oh, okay. Thanks a lot, Dick; appreciate it.
MCC: Okay. We'11 be looking at you.
CDR: Okay; we're standing by for the rest of the com- ments you may have on the circuit breaker, et al.
CC: Roger. We'11 be with you in Just a couple of minutes.
CDR: Houston, 15; go.
CC: Just a quick note on the - on the circuit breaker on the illumination, and then a procedure that might clarify a couple of things for us. First of all, there's a - a number of numeric and won't go into all of that. The main thing is the panel 122 DSKY down there. The - As far as we can see at the moment, there is some possibility that we still have illumination on your status lights on that DSKY, and if we could go through a small procedure here, we may find out whether or not there will be illumination on this. Stand by.
CC: 15, this is Houston. Are you reading?
CDR: Go ahead, Karl.
CC: Right. Back to our lighting circuit breaker. Let me emphasize two main points to start with. I guess under no circumstances do we want to close that circuit breaker. And a second - problem is a - a - a second point is that we don't want to change the INTEGRAL LIGHTING, or the NUMERICS lighting rheostats on panel 100. Let's leave them just as they are. And then there's the - there is a possibility due to the fact that there is a very low amperage shunt going around that circuit breaker, there is a possibility that we do have lights on the DSKY status lights; that is, the UP-LINK ACTIVITY lights, et cetera. And if we can go through a quick procedure here, we'11 find out whether or not we do have lights there. Shall we go ahead?
CDR: Okay. Go ahead, Karl; we'11 take a look at it.
CC: Okay. First of all, on panel 100, again making sure that we do not change the NUMERICS and INTEGRAL lighting switches, can you tell us the position of those two switches, those two - rheostats?
CDR: Okay. We'11 tape them into position they are right now.
CDR: Houston, 15_
CC: Go ahead. 15, this is Houston. Go ahead.
CDR: Okay, Houston. We Just did a little checkout for your LEB DSKY, and the KEY RELEASE light doesn't work - for one - does not work.
CC: Roger. I guess you are a couple of steps ahead of us there. Can you tell us the position of - of the NUMERICS knob over on panel 1007
CDR: About 2 o'clock.
CC: Roger. I guess that's - that's one of our weak points. If - if that switch had - if that knob had been over close to full BRIGHT, we had some chance of getting er,ough energy into those lights to make them work, but in that position, that's probably not possible. And we should leave things as they are.
CDR: Well - well, I - I'm not sure those INTEGRAL lighting rheostats have not been moved since the circuit breaker popped. I guess if you want to, we could run it over to full BRIGHT, or I guess you probably prefer to leave it as it is, and if so, we'11 give up on the status lights.
CC: The word at the present time is let's leave them Just as they are, Dave.
CDR: Okay. We'11 put a piece of tape across so that we don't accidentally run into them.
CC: That's all we have on that subject, 15. You probably know as well as we what lights you're missing up there. We could give you a list if you would like.
CDR: Oh, no. We've got a good handle on it, Karl. Thank you.
CC: I've got one small comment for you, and then a small update to the Flight Plan. First of all, they've init - they've gone through a fairly thorough test on the range rate meter and how it operates under those pressures and in that pure oxygen atmosphere, and so far as we can see at the present time, there is no problem whatever in its operation, but we'11 continue that test. In the Flight Plan at 60 hours on the - on the SIM bay procedure to get some data from the cameras there, I have a small change, if you have the Flight Plan out. Karl.
CC: Right. That procedure should go in this order. First, the S-BAND AUX, TV to SCIENCE, as is already there. Then the PAN CAMERA POWER, on for 5 minutes, and then off. After the POWER goes off, wait for a MSFN cue because we want to pick up some data in t_at - in that state as well. After you get a MSFN cue, then we go to the PAN CAMERA, SELF TEST-off, the MAPPING CAMERA, ON switch to OFF, and then _he S-BAND AUXILIARY, TV-off, in that order. And we're going to need the HIGH GAIN ANTENNA for this Job. And we're going to have a PITCH, minus 30; and a YAW, of 90, and we're going to have to give you cue as to when to start this, so that everything will be lined up right.
LMP: Okay. We copied all that.
LMP: Houston, we copied that.
CC: Roger. And when we come close to the right time, let us know when you're ready to start, anrJ then we'11 let you know when we're ready.
UNKNOWN: 15; Roger.
LMP: Karl, this is 15. We're ready to do that now, or whenever you're ready.
CC: 15, we copied. And stand by; within i or 2 min- utes, we'11 be able to give you a GO.
CC: 15, this is Houston. It looks like we have a 2- to 3-minute wait yet.
CC: 15, this is Houston. You're GO to turn on the PAl! CAMERA telemetry. We need to bring up the HIGH GAIN ANTENNA first and then turn on the PAN CAMERA t el emet ry.
LMP: Roger. We copied.
LMP: PAN CAMETtA POWER is on now.
CC: 15, this is Houston. We're ready for the PAN CAMERA POWER switch, to off.
CDR: Oh, very well. PAN CAMERA POWER is coming off. _-_
LMP: PAN CAMERA POWER is off.
CC: 15, Houston. You can proceed with the rest of that procedure.
CDR: Roger. In work. 39/13 Tape
CC: 15, Houston. We'd like to have OMNI Bravo.
CC: At your convenience, give - give us the WIDE BEA_ on the HIGH GAIN ANTENNA. And the system down here says that your PTC is excellent. In fact, it's one of the best they've ever seen.
CDR: Oh, very good. Okay; you want HIGH GAIN, WIDE BEAM, huh?
CC: We - we don't want to bring up HIGH GAIN; we just want to select WIDE and MANUAL.
CDR: Oh, okay. Okay; we - we do that. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: 15, this is Houston. How are we set for the bistatic radar frequency check?
CDR: Well, we're just about ready for it.
CC: Okay; we're about ready down here, too. Let us know when you're GO.
CDR: Okay; we're configured.
CDR: Houston, this is 15- We're all configured up here.
CC: Roger. We copy, and stand by. 15, we're turning off the up-link now.
CDR: Five square_, Houston.
CC: Good; it sounds like we've got our up-link going again. That next bit down there about ground cue, it'11 be about 20 minutes before we get - get down to that. standing
CDR: Okay. We'11 be by.
CC: I guess we've got all the data we need down here. and You can go ahead turn the VHF off.
CDR: Roger; VHF coming off.
CDR: Houston, 15. GO.
CC: Looks like a very quite night tonight. About the only question we've got for you at the present time is your assessment of the glass cleanup. How did it go?
CDR: Well, we got a - a few more pieces just by looking around over there. Some of the smaller like - oh, I guess the largest piece we found was about a centimeter or so, and the vacuum cleaner picked up a bunch of small chips. I guess - In total, we may have 60 - 70 percent of the portion that broke, and I think we've really picked up all that is practical at this stage.
CC: Roger. Any special places this stuff seems to collect that you can tell?
CDR: I think, initially, we've found most of it was - up near the COAS mount and behind the panel on the left side - near - near the forward part of the window. We found several - several larger pieces there and also one large piece just above the data file, which was about an inch long or so. The small pieces seem to have been drifting all about.
CC: And 15, we didn't forget your state vector. It's just that the one you got on board is very good. We don't need - we feel we don't need an update.
CC: Just polishing off a hamburger and french fries down here. What's on the menu up there tonight?
CDR: Oh, stand by a minute, Karl.
CDR: Hey, Houston, 15.
CDR: Okay, we're just getting ready to do some chlorina- tion here, and we find we've got a leak around the chlorine port - with a cap on it - seems to be leaking water. And you might take a look at that real quick and see if you can come up with any ideas on the thing. The cap is on, and Jim was Just getting ready to take the cap off and noticed a little water; and, in trying to clean it up, it seems like we're accumulating a fair size - fair amount of water right now, right around the cap.
CC: Can you give an - give us an estimate of how many drips per second it is?
LMP: Yes, it's a - it's a pretty good flow right now. Drips per second, it's hard to measure; it's a whole ball of water right around that valve right now.
CDR: What we need is a check valve that we can close or get to, to isolate that port, if we could get one.
CC: Dave, I - I had a problem when I chlorinated on launch day. And, when I first took the valve off, I had about what you've got - quite a strong flow. The cap - the cap stops it from flowing when you and put it back on, after I chlorinated, the flow decreased down to a very slow drip, say once a minute.
CDR: This is a big run, Karl, and the cap is on tight, and it - you can _lmost feel something flowing beneath the cap.
CC: Okay, stand by. Lots of people thinking down here now.
LMP: Houston, 15. It seems to be leaking from behind that panel there, right behind where the waste tank servicing valve is, and the potable tank inlet - and it's accumulating at a pretty good rate.
CDR: Hey, Houston; 15. Got any suggestions yet? We need to isolate this thing pretty quick.
CC: In - just a minute.
CC: What was -
CC: 15, this is Houston. Our recommendation is that on 351, you turn the WATER & GLYCOL TANKS PRESSURE REGULATOR, OFF. On 352, turn the POTABLE TANK INLET, OFF. and
CDR: Okay. POTABLE TANK INLET is now CLOSED, say again the other one.
CC: Up on panel 351, WATER & GLYCOL TANKS PRESSURE REGULATOR, DFF.
CDR: Okay, WATER & GLYCOL TANKS PRESSURE REGULATOR is OFF.
CC: 15, Houston. That should - that should have taken the pressure off of the potable water tank; is it helping the situation any?
CDR: No, it's still leaking, Karl; pretty good rate.
CDR: Houston, looks like maybe we ought to start dumping out of the waste so we can dump out of the potable tanks. It's still leaking and we've got everything but the check valve between the potable tank and the chlorine nozzle isolated.
CC: We copy, Dave. No comments yet. Stand by.
CC: 15, Houston. We note the pressure in your tank coming down. In the meantime, we suspect that the - we suspect that the fitting there on your chlorine and injector outlet is loose, we have - we have a procedure here for tightening it up.
CDR: Okay; give it, quick. 40/5 rape
CC: Roger. We need tool number 3 and tool number W out of the toolkit.
LMP: Okay; 3 and W out of the toolkit.
CC: Right; put - put number 3 in the tool W ratchet, and insert - sert tool 3 in the hex opening in the chlorine injector port.
CDR: Okay. That's - that looks like where it's probably leaking.
CC: And, once we have the number 3 tool in the hex opening, it should go in about a quarter of an inch to really engage. It also says "Use caution when inserting the tool because it comes in contact with a rubber diaphragm."
CC: We've agreed down here it's a good idea to take the water gun to fill up a food bag or something of that sor_.
CC: Once you've got tool number 3 well engaged in that injection port, turn it about a quarter turn.
CDR: Okay, Houston. It looks like that did it.
CDR: Nice to have the quick response you guys have down there.
CC: Well, you'11 never believe it, but after we had the leakage on the morning of the 26th, somebody sat down and wrote up a special procedure, just in case.
CDR: Well, that was good thinking because we about had a small flood up here.
CC: 15, Houston. We're looking now at the best pro- cedure for getting the water system operating again. In the meantime, we trust you have your hands full of water up there.
CDR: Yes. All we have to do now is hang out a few towels to dry, but looks like we're in good shape.
CC: 15, Houston. We'd like for you to turn the REGULATOR back ON, on panel 351.
CDR: Okay. REGULATOR coming back ON.
CC: 15, Houston. Is everything looking all right on the ]eak now?
CDR: Yes; it locks okay. That fitting there that we tightened Up went somewhere between - 180 - 270 de- grees of turn. And that - that was where the water was coming from, and it looks like it's secure now.
CMP: Hey, Karl, we just ran a little check with our slide rule here, and it was something like 3000 drips per minute.
CC: Okay; glad to hear that good news. I - I guess up there you don't get drips, do you; that's an interesting fact.
CC: Okay, Dave. We're ready to open the INLET valve to the POTABLE WATER TANK.
CDR: Okay; POTAt_LE WATER INLET coming OPEN.
CC: Incidentally, Dick was over at Lurton's and they called up to say, "Hey, it's about time you take a bath up there."
CDR: Well, we were sort of discussing that a little earlier tonight anyway. And, as a result, well, I guess we all got cleaned up.
CDR: And, Houston, with the fitting secure now and everything shipshape, what do you think about proceeding ahead with the chlorination?
CC: Okay, Dave. Go ahead.
CC: 15, this is Houston. The word here is to go ahead.
CC: 15, this is Houston. Are - are we in comm now?
CDR: Roger. We've got you. With everything looking shipshape down here, what do you think about pro- ceeding with the chlorination?
CC: 15, this is Houston. Is Jim doing some exercising now? We're doing a little medical detective work down here.
CDR: Well, yes, as a matter of fact, he is. He's trying to get one of the compartments open.
CC: ... with you.
CC: 15, this is Houston. Please disregard.
CDR: Okay, I'11 disregard.
CC: 15, Go ahead.
CDR: Okay; we've got the presleep checklist if you're ready to copy.
CDR: Okay; crew status is good. No medication today. Onboard read-outs: BAT C, 37.0; pyro BAT A, 37.2; B, 37.2; RCS A, 89; B, 86; C, 89; and D, 86. And the H 2 fans have been cycled, and the potable water has been chlorinated, and the vents and switches are all set. The cabin's at 5.7, and I'11 give you an E-memorydump any time yo_'re ready.
CC: We copy; and stand by on memory dump.
CDR: Okay; you might be interested in another little item. All the meals have been consumed on sched- ule, and the - the pantry's even had a pretty rigid test so far.
CC: Excellent.
CDR: Here, our trusty LMP came up with an interesting analogy relative to the last event. He wondered if the original Endeavour had ever sprung a leak like that.
CC: Okay; thatTs a good question. We'11 get our his- torians ou$ to check that one. Hey, what did you do with all that extra water, stick it overboard
CDR: Oh, no; we_ve got a bunch of towels hanging up in the tunnel right now. It looks like somebody's laundry.
CC: Cy's down here guessing that you hosed some of it overboard.
CDR: Well, you probably saw the motion of the spacecraft. We were Just in that process when you came up with a procedure.
CC: (Laugh) Okay; fine. The PTC's still looking great.
CC: Okay, Dave. We're ready for the E-MOD dump.
CDR: Okay; here it comes.
CC: 15, Houston. We finished the E-memory dump. The surgeon - the surgeon says that it's - it's your turn in that biomed harness. And, otherwise, we - don't have any - anything more down here. And, we're ready to secure - the - the voice communica- tions any time you like.
CDR: Okay; very well. By the way, how are the biomed harnesses working out for the surgeons?
CC: The word is that we're getting good clean data, and they're very happy with it.
CDR: Okay; very well. See you in the morning.
CC: Roger, Good night. E_O OF TAPE 42-45/1 Tapes REST PERIOD - NO COMMUNICATIONS APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: Roger. Good morning, Dave. It's time to rise and shine.
CDR: Okay, Bob. Good morning.
CC: And we've got the usual quota of checklist changes, Flight Plan updates, et cetera. When you guys are ready, give me a call. Look like yo u g_s had a good night's sleep last night, for you anyway, Dave.
CDR: Okay. Felt pretty good. We'11 get organized and give you a call here in a few minutes.
CDR: Good morn:!ng. I have a consumables report for you, and sleep report.
CC: Okay. We're ready to copy.
CDR: Okay. On the Commander: PRD 7 and 1/2 hours sleep; CMP: 25012, same sleep; LMP: 08013, same amount of sleep. On the consumables: 70:15; RCS, 90, 87, 84, and 88. On the H2_ 90, 89, and 60. 02; 88, 89, and 65. Over.
CC: Roger. And, before I read that bac_we did not catch the commander's PRD reading.
CDR: That was 23046.
CC: Roger. Copy. Understand we have Commander's PRD, 23046; 7 and a half hours sleep for all three crew- men; 25012 for the CMP; and 08013 for the LMP. And we have consumables update, based on our figures from the ground. For 70:00, we have 84 percent total. And we have 85, 84, 84, and 85. And for H2, we have 91, 90, and 60. For 02, we have 89, 90, and 73. Over.
CDR: Roger. I ... I'm ready for any Flight Plan update you might have.
CC: Okay. First we have Flight Plan update for the day. We'11 start out at - Stand by.
CC: 15, Houston. You back with us again?
CC: Roger. We've been here all along, Bob.
CC: Roger. We had the usual signal break when we went around in PTC there. Let me ask you one question. The EECOMs are interested in getting a verification on the 02 tank 3 readout, since there's a difference of 8 percent there. And, then after we get that, we'11 proceed with this update. It's a very long one, so I guess you might as well - -
CC: - - drag out your Flight Plan.
LMP: Okay. We're reading - 74 on board.
CC: Roger. Understand 74. Okay, Jim. And we'11 start this Flight Plan update at 71 hours, so you can tell me when you get there.
UNKNOWN: Okay. I'm there.
CC: All right. At 71 houra, we want to add the follow- ing information. "HIGH GAIN ANTENNA on MSFN cue," and note that we won't stop PTC. We'11 have to give you the nt.mbers, depending on where you are - in PTC, as we come around at this point. Second line is "S-BAND AUX TV to SCIENCE, PAN CAMERA MODE to STANDBy. '' That's a "Verify." "PAN CAMERA POWER, on. PAN CAMERA SELF TEST to HEATERS. MAPPING CAMERA, ON to STANDBY. Then after 5 minutes, PAN CAMERA POWER, OFF, and S--BAND AUX TV, off." Copy?
LMP: Okay. Here's the readback, Bob. At 71 hours, "HIGH GAIN ANTENNA on MSFN cue, S-BAND A_UX TV to SCIENCE, PAN CAMERA MODE to STANDBY." That 's a "PAN "Verify." CAMERA POWER, on; PAN CAMERA SELF TEST to HEATERS; MAPPING CAMERA, ON to STANDBY; after 5 minutes, PAN CAMERA, OFF, and S-BAND AUX TV, off." 71:15.
CC: Roger. That's good. Okay. Next item at This will be a line added in after the "CM/LM pressure equalization decal." And the line says, "PRESS equal valve, close." Over.
CC: Roger. At 71:15, "PRESSURE equalization valve, close."
CC: Roger. And next one is on 73 hours and 15 minutes.
LMP: Okay. Go. An
CC: Okay. d at 73:15, we will delete the line re- ferring to waste water dump. "Waste water dump" will be deleted.
LMP: Okay. I copy. Delete the "waste water dump."
CC: Okay. Next one will be at 81:42, 81:42.
CC: Okay. And, in the configuration for the camera there, we're changing that from "CM 4" to "CM 3,¥' on the second line.
LMP: Okay. "CM 3" is ... to "CM 4."
CC: Roger. Next one's on 84:24, 84:24.
LMP: Okay; go.
CC: Roger. Also, configuration of the camera, and we'11 change that one also to "CM 3" instead of "CM 4."
CC: Roger. And then over on the other side of the page at 84:40, again terminator photos. The first one, the first line there, 84:40 will now read "EL, on," and the time will be "T-START minus 1:40," 1:40.
LMP: Okay. I copy.
CC: And then at 84:42, "EL, off" will now be at "EL, off, parenthesis, T-START."
CC: I copy.
CC: Okay. And we have two general notes. One refers to SIM door JETT, and it's a reminder that we verify that the Lexan shield is mounted in - window 5, with the cardboard shade off, for a photograph of the SIM door JETT. At - this is about 74 hours.
CC: Okay. I understand.
CC: Okay. And second one is with respect to the optics CALs. And I guess we should explain here that - people who are wringing their hands down here about the fact that we looked at a little bit of a bias drift when you guys zeroed the optics the first sent day, and we up some procedures yesterday say- ing to be careful when you are doing it for P23. And then everybody else got - decided that we ought to be careful when we did it for other things be- sides P23. And so, we have the following procedures, which are, basically, to avoid trunnion rates for all optics zeroing, so that we don't get any - pos- sible shift on the mirror calibration. And the procedures are nwofold. First I guess you might write them down some place -- if the OPTICS power is off, place ZERO switch OFF before turning the optics power on. And then, after the power is on, drive the optics manually to a trunnion of less than 10 degrees before placing the ZERO switch on. Over.
CC: Okay, Bob. If OPTICS power off, then OPTICS ZERO switch, ZERO?
CC: Roger. It really is, if OPTICS power off, place the ZERO switch to OFF before turning the optics power on.
CC: 15, Houston again.
LMP: Bob, would you read that procedure again? I want to make sure I have it correct. I have OPTICS power off, then OPTICS ZERO switch, ZERO.
CC: Okay, Jim. The thing is, if your optics power is_ off, we - as it will be like this morning, is OFF_, we - as it will be like this morning, and the ZERO switch is already on, as it probably is this mornr ing, we want you to place the ZERO switch to OFF before you turn the OPTICS power on, because, otherwise, it will then automatically zero withou_ you having control over it. Do you understand?
CC: Okay. And - the corollary - -
LMP: Read the - read the rest of it after the 0P - -
CC: Okay. And then after, - Okay; I'11 - I'11 read it through from the beginning again. If OPTICS power off, place ZERO switch OFF before turning OPTICS power on. Then, drive OPTICS manually to TRUNNION less than 10 DEGREES before placing ZERO switch ON. Over,
LMP: Okay. That was after the OPTICs power ON. Drive optics until trunnion is less than 10 degrees be- fore ZERO switch ON.
CC: Roger. And the corollary to that is if the optics power is already ON, then we drive the OPTICS power manually to a trunnion of less than 10 degrees before placing the ZERO switch ON. That's the sec- ond part.
LMP: Okay. We copy.
CC: Okay. And then I have an update to your Contingency Checklist, page 4-3 which pertains to LOI burn rubles, if you can get that out.
UNKNOWN: LMP Okay, Bob. I have the Contingency Checklist.
CC: Okay. I got 4 - page 4-3.
LMP: Okay; I have 4-3.
CC: Okay. And these changes are basically in the table there. - We'11 start out under the heading of "Burntime." And that first one will be change from "00 to 1:36," now, instead of "1:35." So, it'11 be 1:36 in the first burn time. The second line will be "1:36 to 1:57." And the third line will be "1:57 to 2:13." And the fourth line will be "2:13 to 3:11." Over.
CC: Okay, the next one in the second Coll,mn, "DELTA-VM," the lines will be 0 to, or "0-640, 640-784, 784-900, -- 900-1313." Over.
UNKNOWN: I copy.
