Spacelog Apollo 13

Aquarius, Houston.

Go ahead.

Jim, when you get finished moving your stowage around and it's convenient, we'd like to terminate the battery charge for a little while to bring up the CM TM so we can take a look at the temperatures again, like we did yesterday. Advise that right now on your batteries, you have 111 amp-hours; and, eventually, we hope to have them up—peaked up to about 116. One other point, we—we can either read that procedure up again which involves cranking up the telemetry, or, if Jack still has it, we can use his notes and—but I have one or two changes to—to make on them. Over.

Okay, understand that you'll want us to terminate battery charge for a while, and crank up the CM TM to read out temperatures. And you have a few changes to Jack's checklist, and I'll turn the COMM over here to Jack shortly, as soon as he's finished, and we'll get along with it.

Houston, Aquarius.

Go ahead, Jim.

Just out of curiosity, Vance, what's our distance and velocity now?

Hey, stand by 1. You're speeding up, I think.

Jim, we have you 101 000 miles out, and your velocity is 5848. Starting to speed up.

Okay. Thank you.

Okay, Houston; Aquarius.

Go ahead, Jack.

Okay, Vance. Jim said that you want to terminate battery charge on battery A.

That's affirm, Jack. Request to—Before you terminate it, get the usual readout on voltage and current; and we'd also like a time of termination, and understand you have the termination procedures. Is that affirm?

Okay. That's affirm. Stand by. Let me just make sure I've got everything here before I go off on a tangent.

Okay, Jack, and your battery-charge termination procedure remains unchanged, but when we go to power up the CM and look at your TM, we have a couple of additional steps.

Okay. Vance, I do have the procedure for stopping the battery charge. And do you want me to copy this procedure now, or do you want me to come back and give you the volt, amps, and time and—after I complete this termination?

Okay. Just—just give us the volts and amps just before you start the termination of the procedure, and understand you say you have the charge—the procedure for taking the charge off. Is that affirm?

That's affirm.

Okay. And just give us a hack on the time —

And you want to—you want to review it at all?

Negative. Unless you want me to. I'll tell you what; I could run through it very quickly just to verify that we're getting started off on the correct path here.

Yes. Okay, the first four or five things that I have is panel BAT CHARGE to OFF on panel 3; AC INVERTER 2, OFF; panel 5: MAIN BUS TIE, BAT A/C ON; panel 250: CB BAT A POWER ENTRY/POSTLANDING, open; panel 275: INVERTER POWER 2, MAIN B, open; and then, the—just to go ahead and reverse the position of the switches and circuit breakers that I started out with, and these don't have to be in reverse order. Is that Charlie?

Roger, that's—that's Charlie. Have at it.

Okay, we'll get a volts and amps right now.

Okay.

Okay, Vance. The volts and amps: 39.4; amps, 1.25.

Okay, Jack. We copy that. Incidentally —

Okay. We're going up to termin—Go ahead, Vance.

Never mind, Jack. I'll bring this up later when you've finished the procedure.

Okay. I'm going off the air; I'll put Fred-o on. I'm going to stop the battery charge.

Okay.

Now, how do you read, Vance?

Hey, loud and clear, Fred. Understand you've been doing some spring housecleaning, moving stowage around up there.

Boy, you wouldn't believe this LM right now; it's nothing but bags from floor to ceiling.

Hey, that brings up a question. We were wondering where you guys plan to stow the probe and drogue? It occurred to us that one possibility was to stow it in the LM, down about where the LMP normally stands, underneath the IS—ISAer. Perhaps you have a better idea. Over.

Yes, I do, Vance. … would go in the LM, but I thought maybe we ought to stow it where the CDR stands. How's that?

Okay. I can tell that you're just getting—getting that one over because Jim just got off the loop.

Yes, he's sleeping. No, that's—that's actually where we normally had been stowing it for normal LM JETTs.

Okay, and—Hey, we just—we'll record that, and figure that you'll stow the probe and drogue over in the—where the CDR stands. We have a—a change to this—equipment transfer list that I just read up to Jim. Why don't you make a note of this one item? Forget about the LM —

Stand by; stand by 1.

Okay.

I think Jack hauled off the piece of paper with that—all that on it. Why don't you hold it until Jack gets done doing the battery charge?

Okay.

And, Fred, request PCM on LO bit rate, now.

Okay. And there was one piece of flight data that we needed that we didn't bring along this time.

What was that?

That's a big book with a lot of just plain old blank pages in it.

Yes, when you—when you get off nominal, why you just need scratch paper, don't you?

Yes.
