Spacelog Apollo 13

Yes. Just stand by.

What'll it take to …

Yes.

You only got two … there, so …

I will.

We'll pull one out someways, I guess. We've gotta watch that one right there.

It's decreasing now. It'll—it'll—It's cold. I noticed that in the command module. It'll wobble.

Houston, Aquarius.

Switch OMNIs to TRANSMIT.

Houston, Aquarius.

Go ahead, Aquarius.

Roger. Are you planned to set up here very shortly—a powerdown procedure?

That's affirmative, if you'll take out your contingency book and turn to page Power 6. Over.

Roger. Stand by. Contingency Power 6. Get the book over here. Contingency Power 6.

Well, I hope this …

And while you're doing that, let's put ATTITUDE CONTROL, three, switches to MODE CONTROL.

All three ATTITUDE CONTROL switches have been in MODE CONTROL.

Okay. And when you get to Power 6, you ought to see a circuit breaker page, panel 11.

Have a pencil? Let's see it—thank you.

Okay. I have Power 6, panel 11.

Okay. On Power 6, panel 11—The top three rows, configure them as you see them.

Okay, now, Jack … We have put the TCAs in for the previous procedure. Do you want those out, now?

That's affirmative, Jim, Pull them out. TCAs open.

Okay. I'm changing those to … back again. First three rows. And you're pulling the ATCA PGNS, huh?

That's affirmative. Pull ATCA PGNS open.

Okay. I've done that.

Okay. Are you ready for the fourth row?

Affirm.

Okay. Now when we get in the fourth row, we're going to open the IMU OPERATE circuit breaker; and what that means is that we're going to lose the capability to watch your CDUs, so we're not going to be able to see your attitude. Therefore, we will not be able to advise you on which antenna to select for communications. The way we want you to handle that is to turn the LM UPLINK SQUELCH off, and when you hear the noise, switch antennas. We'll be able to see you switch antennas, and it's going to take us about 3 to 5 minutes to establish a lockon again after you switch. After each time that you switch antennas, we will initiate a voice check. And basically when you see the Earth out the window, you can be on FORWARD antenna, and when the Moon's up in the window use the AFT antenna. You copy?

Okay. We're going to pull the IMU OPERATE circuit breaker, so you won't be able to see our attitude. Therefore, you won't tell us how to switch antennas and we'll enable the—I will turn the—up the SQUELCH OFF so that when we start getting any static, we'll switch antennas and as a thumb rule we could use—with the Earth forward, we use the FORWARD antenna and when we see the Moon we use the AFT antenna.

That's affirmative, Jim. In other words, we're leaving the antenna switching up to you, and after you switch antennas it's going to take 3 to 5 minutes for us to establish a lockon again, and we'll initiate a voice check. And I'm ready to go on panel 11, row 4.

Okay.

Okay. On row 14, under HEATERS RCS SYSTEM A/B-1: open QUAD 1 through 4; under ECS, the only change is—under GLYCOL PUMP close AUTO TRANSFER; under COMM, the only change is: open VHF A RECEIVER, open COMMANDER AUDIO; under PGNS, the only change is: close and leave closed IMU STANDBY circuit breaker, so we can have heaters. Read back.

Okay. On row 4, we're going to open all four of the heaters—the RCS SYSTEM A and B—the first four circuit breakers. We're going to close the AUTO TRANSFER. We're going to open the VHF A RECEIVER and the COMMANDER AUDIO. And we're going to close the IMU STANDBY. The LGC DSKY and the IMU OPERATE will be open.

That's affirmative, Jim. All other breakers in that row are as you see them in the checklist. And on row 5, the only change is that we want you to, under EPS, open ASCENT ECA CONTROL. Over.

Roger. I think we already have that opened—ASCENT ECA CONTROL is probably already open.

Okay. So let me confirm. We'll have one COMM system, that will be the LMP system, and we'll have to do our own antenna switching; therefore, we'll have to wait about—Okay, why don't you switch? Aft antenna.

We'll have to wait for you to get a lockon again. Is that correct?

That's affirmative, Jim. You'll be working off of the LMP's panel over there.

Okay. What else do you have for me?

Okay. Panel 16, that's on page Power-7. Top row, the only change is: under RCS SYSTEM B, open PQGS/DISPLAYS. Over.

Okay. I may go over this with you, Jack, because this checklist has been written over two or three times now on our various procedures. Top row, the first two are open, the next three are closed, and we're going to open now the QUAD TCA's 1, 2, 3, 4; CROSSFEED will be closed, and the TEMP/PRESS DISPLAYFLAG will be opened, and we're going to open up the PQCS, MAIN SOV will be closed, and the … will be opened.

That's affirmative, Jim. And there's no change to the second row. Over.

Okay. Again let me go through this with you. The first four are going to be closed. The next sev—eight will be—the next nine will be open from LOGIC POWER B through DESCENT ENGINE OVERRIDE How about the CWEA? Is that going to be closed?

That's affirmative, Jim. We want the next five closed.

Okay.
