Spacelog Apollo 13

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.

Okay.

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.

Yes, Ken. It was, I heard about it.

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.

Okay. Panel 8: SEQ PYRO ARM, two, to SAFE.

Okay. And following this, we take SEQUENTIAL, LOGIC, two, to OFF.

Okay. LOGIC, two, to OFF.

I'm sorry, Jack. I'll have to ask you to repeat that.

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?

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.

Okay, real fine.

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.

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.

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.

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.

That's affirmative. Okay, now we're going to panel 5, and it's circuit breaker G&N, COMPUTER, MAIN B, closed.

Okay. Panel 5: CB G&N, COMPUTER, MAIN B, closed.

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.

Okay. You're saying that I will probably get a PROGRAM 06 with a VERB 37 ENTER flashing.

I expect that you —

ENTER 06.

I expect you are —

Say again, Ken.

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.

Okay. Is there anything else I could get?

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.

Will you be getting it on downlink?

No, sir. We don't have that powered up yet.

Okay. I'll yell to Jim, and Jim will give you a call.

Okay. The basic thing, Jack, is just to get the computer in standby to save power.

Okay.

And we need another battery B readout.

Okay. He is on his way. Go ahead.

Okay. Now, we're at EI minus 2 plus 30; we're going to panel 5: circuit breaker ESSENTIAL INSTRUMENTATION, MAIN A, closed.

Okay, CB ESSENTIAL INSTRUMENTATION, MAIN A, closed.

That's correct. Now circuit breaker G&N, IMU HEATER, MAIN A, closed.

CB G&N, IMU HEATER, MAIN A, closed.

That's correct. CB LM POWER-1 and -2, open.

CB LM POWER-1 and -2, open.

That's correct. CB G&N, COMPUTER, MAIN A, closed.

CB G&N, COMPUTER, MAIN A, closed.

Okay, Jack. And that's correct. I got it out of sequence. Would you put that COMPUTER, MAIN A, ahead of LM POWER?

Okay, Ken. That's CB G&N, COMPUTER, MAIN A, closed, goes before CB LM POWER-1 and -2, open.

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.

All right, and POWER, PMP, to NORMAL.

POWER, PMP, to NORMAL.

That's correct, and UP TELEMETRY, COMMAND RESET to RESET and then NORMAL.

UP TELEMETRY, COMMAND RESET to RESET, then NORMAL.

Okay. On panel 2: UP TELEMETRY, CMC, to ACCEPT.

UP TELEMETRY, CMC to ACCEPT.

On panel 275: circuit breaker FLIGHT/POSTLANDING, MAIN A and MAIN B, closed.

A panel 275: CB FLIGHT/POSTLANDING, MAIN A and MAIN B, close.

That's correct. And configure for COMM on panels 6, 9, and 10.

Okay.

Okay, are you with me?

All right. I assume you got that. Panel 5: circuit breaker IMU, MAIN A and MAIN B, closed.

CB IMU, MAIN A and MAIN B, close.

That's correct. Circuit breaker OPTICS, MAIN A and MAIN B, closed.

Okay. CB OPTICS, MAIN A and MAIN B, close.

That's correct. CB G&N, POWER, AC1 and AC2, closed.
