Okay, Deke. All the windows in the command module are heavily coated with water right now. So I don't know what kind of pictures we'll get out of them, but I'm going to try and clean them off and do the best I can with the 250-millimeter lens on the Hasselblad.
- Deke Slayton
-
Roger. That's why we have the top priority stuff in the LM. We figure you've got a much better chance of getting it through there.
- Vance Brand (CAPCOM)
-
Jack, before we start reading the procedure, we'd like—We find that BAT A is topped off and in great shape. Like to switch over and top off BAT B some more. Give it 2 more hours of charging. Have about a seven- or eight-step procedure here to give you, if you want to copy that. We're switching before we start recording the entry procedures.
- Vance Brand (CAPCOM)
-
Okay. Panel 3: switch BATTERY CHARGE to OFF. Panel 5; MAIN BUS TIE BAT A/C to BAT A/C; CB BATTERY CHARGER, BAT A CHARGE to open; CB BATTERY CHARGER, BAT B CHARGE, close. Next, panel 250; CB BAT B POWER ENTRY/POSTLANDING to close. Panel 5; MAIN BUS TIE, BAT B/C, off. Panel 3; BATTERY CHARGE to B. Advise; well, stand by. Jack, advise that we have a backout procedure for this, but we'll read that up to you later, in about 2 hours. And, also, that this procedure is a DELTA to your—the first battery charging procedure that we gave you. In other words, it's a DELTA from where you are right now.
- Jack Swigert (CMP)
-
Okay. This is the procedure for charging BAT Baker. Panel 3; BAT CHARGE, OFF; panel 5; MAIN BUS TIE, BAT A/C to A/C; CB BAT CHARGER, BAT A CHARGE, open; CB BAT CHARGER, BAT B CHARGE, close. Panel 250; CB BAT B POWER ENTRY and POSTLANDING, close. Panel 5; MAIN BUS TIE, BAT B/C, to OFF; Panel 3; BAT CHARGE to B. This is a DELTA for the first battery charging procedure; you'll give me the backout procedure in a couple hours.
- Jack Swigert (CMP)
-
Okay. I'll put it in work right now, then come back and stand by to copy the rest of—well, I—not the rest—everything.
- Jack Swigert (CMP)
-
Okay, Vance. I put BAT Baker on charge; I don't think it quite had stabilized. It was reading 1.1 amps, 39.6 volts when I left up there.
- Vance Brand (CAPCOM)
-
Jack, we're going to need readings on the BAT volt and charger amps about every 10 or 15 minutes for a while, so is there somebody else that can be reading them out while you're copying? Over.
- Jack Swigert (CMP)
-
Yes. Jim will take a run up there. Fred-o is sleeping right now. We're trying to get some sleep here, and Jim'll run up and take a look at voltage and current whenever you call.
- Jim Lovell (CDR)
-
Vance, we've got to realize that we've got to establish a work-rest cycle up here, so we just can't wait around here to just read procedures all the time up to the burn. We've got to get them up here, look at them, and then we've got to get the people to sleep. So take that into consideration when you get ready to send up the pads.
- Vance Brand (CAPCOM)
-
I know, Jim. We're very conscious of that. We—we should be ready to go in about 5 minutes. That's all I can say. Stand by.
- Vance Brand (CAPCOM)
-
And, might as well bring the COMM up to a higher fidelity for this long period of checklist reading. That requires, panel 16: CB PRIMARY S-BAND POWER AMP, closed.
- Vance Brand (CAPCOM)
-
Okay. And next step, panel 12: S-BAND FUNCTION to VOICE and RANGING FUNCTION to RANGING.
- Jack Swigert (CMP)
-
Okay, Vance. The S-BAND FUNCTION is at VOICE and the RANGING switch was at RANGING.
- Jack Swigert (CMP)
-
Okay. Can we—Since the first part of it, you're just going to read and I'm going to copy and we're going to have a question and answer period later, can we get started?
- Vance Brand (CAPCOM)
-
Okay. Procedure's coming back in again. Multicopies for distribution. And Ken's back. He's a local expert on this now, so we'll turn you over to him and he'll read it off.
- Jack Swigert (CMP)
-
Okay. Stand by. I'll give you volts and amps. Okay. The voltage is 39.1; amps, 1.75.
- Ken Mattingly
-
Okay. Let me take it from the top here. Just—there might be some overlap, but to make sure we're all on the same signal. We're starting off with a set of time line procedures that are going to give us—end up with the normal entry checklist. There will be some checklist changes into the book, but the bulk of what I have for you is the time line stuff. And it starts at 6 hours and 30 minutes prior to EI and assumes that we're getting LM power to MAIN B in the command module. I think you already have the numbers for the LM pads and the command module pads; I mean the types of pads we'll be giving you. And if you have a question on what they'll be doing or what they're for, I can go over those now or when we get through.
- Jack Swigert (CMP)
-
Okay. Yes, I'll make a little note there, and we'll discuss it when we get everything copied, huh?
- Ken Mattingly
-
All right. And the first item, then, after you get ready to start this checklist, is to install lithium hydroxide canisters and to stow ORDEAL. On panel 8, we want to turn the FLOODLIGHTS to FIXED.
- Ken Mattingly
-
Okay. I'll tell you. I'll go line at a time and wait for your verification before I go on to the next one. I have panel 8, FLOODLIGHTS, FIXED,
- Ken Mattingly
-
Okay. That's the panel 8 floodlights. Now we're going to take panel 5 and put the FLOODLIGHT rheostat to FLOOD and the LEB, that's panel 100, FLOODLIGHTS are also going to FIXED. And the purpose of this is to balance up buses A and B.
- Jack Swigert (CMP)
-
Okay. Panel 5; FLOODLIGHTS; you want the rheostat on. Panel 100, FLOODLIGHTS; you want FIXED.
- Ken Mattingly
-
That's affirmative. Okay. On panel 8: circuit breakers EMS, MAIN A and MAIN B, that's two, open.
- Ken Mattingly
-
Okay. That's correct. On panel 5: circuit breaker BAT CHARGE, BATTERY A CHARGE, closed.
- Ken Mattingly
-
All right. Like to take MAIN BUS TIES, two of them, on and up. That's probably a verify.
- Jack Swigert (CMP)
-
Okay, Ken. Wait on that one here. I'm just about to lose you here. Just—I've got to change OMNIs.
- Ken Mattingly
-
Okay. Good. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.
- Ken Mattingly
-
All right. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.
- Ken Mattingly
-
That's affirmative. Okay. Panel 5: circuit breaker CENTRAL INSTRUMENTATION POWER, MAIN B, closed.
- Ken Mattingly
-
Okay, Jack. We want to put the PRIMARY and the SECONDARY EVAPORATED WATER CONTROL valves to AUTO.
- Ken Mattingly
-
Okay. Thank you. All right, the next little step after your water control valves is to perform the CSM RCS preheat. We'll do that on page E/1-5, steps 35 and 37.
- Ken Mattingly
-
That's affirmative. Now back to panel 5: circuit breaker CAUTION AND WARNING, MAIN B, closed.
- Jack Swigert (CMP)
-
Okay, Ken. The COMM from you is awful weak—awful weak, I—I can't—it's CB EPS SENSOR UNIT. Say again, after that.
- Ken Mattingly
-
All right, Jack. That's CB EPS SENSOR UNIT, DC, that's Delta Charlie, BUS A and B, closed.
- Jack Swigert (CMP)
-
Okay. CB EPS SENSOR UNIT, DC BUS A and B, close. And I'll give you the volts and amps.
- Ken Mattingly
-
That's affirmative. Okay, now we're at EI minus 5 plus 05. And, as far as you're concerned, Jack, the command module is using this for information only. This will be the LM doing an Earth-terminator AGS alinement; and at the time of 5 plus 05 is the time they'll be going ahead and releasing their ball. And this will be covered in the LM checklist; it'll be uplinked after this one. At EI minus 5, we perform midcourse number 7. Over.
- Jack Swigert (CMP)
-
Okay. At EI minus 05:05, the LM is making an Earth-terminator aline; and at EI minus 05:00, we perform MCC-7.
- Ken Mattingly
-
That's correct. At the completion of midcourse 7, the LM will maneuver to a separation attitude. And this attitude will be sent up on one of the pads that you're going to get before all the sequence starts. And it'll be flown to the LM ball angles on that pad.
- Ken Mattingly
-
All right. At EI minus 4 plus 40, we want to perform page 1-6, step 39 of the entry checklist.
- Jack Swigert (CMP)
-
Ken, I—I didn't get it. We had to change OMNI's again. Could you say it—the EI minus 4 dash—or 04:40, we do something.
- Ken Mattingly
-
That's correct. Okay. The next is the command module RCS activation, and that's step 4-1 of page E/1-6.
- Ken Mattingly
-
All right, Jack. The next is at EI minus 4 plus 30. We want to verify that the LM is configured for command module RCS hotfire.
- Jack Swigert (CMP)
-
Okay. Let's repeat it. Stand by. Cut out. We've really got a strange attitude, so this is why we are having the COMM problem. Panel 5: CB G&N IMU HEATER, MAIN B, closed.
- Ken Mattingly
-
That's affirmative. On panel 1: ROTATION CONTROL POWER, NORMAL. That's two of them, to AC/DC.
- Ken Mattingly
-
That's negative, Jack. We haven't powered up any of the downlink at this time. You'll be doing this and the command module RCS pressurization both by yourself.
- Ken Mattingly
-
Okay. Now, the next event is going to be the separation of the service module, and these are some LM steps, but so that you will know what is going on, I'll read them to you. The LM will do a LM plus-X of one-half foot per second. Then you'll be hitting the CM SM SEP on and up, on their command. As soon as we are free of the service module, the LM will do another LM minus-X for 0.5 feet per second. This is called the push-pull maneuver. I think it was described this afternoon.
- Ken Mattingly
-
Okay. I just wanted you to know that's the sequence you're in. Okay. At the completion of that, we go back to panel 8, and it's SEQUENTIAL, PYRO ARM, both of them, to SAFE.
- Jack Swigert (CMP)
-
Okay. Panel 8: SEQ LOGIC, two, to OFF. Are they ON now, Ken? I don't remember turning them—I guess that's part of one of the other sequences, huh? That we turned them ON?
- Ken Mattingly
-
That's affirm. The reason we're turning the logic off, Jack, is a power savings. So we'll be turning them off, and I'll be getting them back on when we go to get off of the LM; and then turn them back off, then we'll be turning them on prior to entry. Just so you know what's coming.
- Ken Mattingly
-
Okay. Then following this, the LM will pitch up to acquire the Moon—Excuse me, they're going to pitch up and acquire the service module and photograph, and they'll be using the ACA for rotations from now on. And you may see the LM out of window number 5 at the same time they pitch up to acquire it.
Expand selection down Contract selection up - Jack Swigert (CMP)
-
Okay. The LM pitches up, acquires the service module and photographs it, and I should expect to find—might possibly see the service module out of window 5.
- Ken Mattingly
-
That's affirmative. Okay, now we're down to EI minus 3 hours, or the next time-event, and the LM starts a maneuver to what we call the Moon-view attitude. This maneuver is designed to place the command module optics pointing with zero zero at the Moon, and it will be flown to on the LM ball angle.
- Jack Swigert (CMP)
-
Okay, the LM maneuvers to the Moon-viewing attitude which would place the Moon in the center of the command module optics with them at zero zero.
- Ken Mattingly
-
That's affirmative. Okay, now we're going to panel 5, and it's circuit breaker G&N, COMPUTER, MAIN B, closed.
- Ken Mattingly
-
That's affirmative. Now you're going to come up with a 37 ENTER 06 ENTER most likely on the computer. And what we want to do is to put the computer to standby; if you come up with a 37 06, you'll have to do an ENTER in order to get the code 62. If it's got 62 on it, you can do a PROCEED until the DSKY blanks. You might remember that the AC is still off at this time so you won't be getting the STANDBY status light, and your cue that the computer is indeed in standby is when the DSKY goes blank.
- Jack Swigert (CMP)
-
Okay. You're saying that I will probably get a PROGRAM 06 with a VERB 37 ENTER flashing.
- Ken Mattingly
-
Yes. We think that you're going to come up with a 37 06 already in the DSKY. If you do, do an ENTER and that should take you to the code 00062, which is the request for standby. And when you get that, hit PROCEED until the DSKY blanks. If you come up with something else, that's where we want to end up anyhow. With either, when you get the code 62 when it comes up, just do a PROCEED on it.
- Ken Mattingly
-
I don't believe so, Jack. That's one that when you get to that step, if you do get something else, we will be standing by to see that you see. The whole scheme is to go to standby.
- Ken Mattingly
-
Okay. Now, we're at EI minus 2 plus 30; we're going to panel 5: circuit breaker ESSENTIAL INSTRUMENTATION, MAIN A, closed.
- Ken Mattingly
-
Okay, Jack. And that's correct. I got it out of sequence. Would you put that COMPUTER, MAIN A, ahead of LM POWER?
- Jack Swigert (CMP)
-
Okay, Ken. That's CB G&N, COMPUTER, MAIN A, closed, goes before CB LM POWER-1 and -2, open.
- Ken Mattingly
-
That's correct. Jack, what we're doing is we've had the LM powering MAIN B, and we've had all these particular loads on it, and we're getting ready to secure LM power so we wanted to make sure that essential things like the computer, the platform, and all have dioded power supplies before we remove the LM power.
- Ken Mattingly
-
Okay. Thank you. All right, now panel 275: circuit breaker MAIN B, BATTERY BUS B, closed.
