Spacelog Apollo 13

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.

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.

Okay, Vance. I got the stowage list now.

Okay, I gave you two lists —

And Jack's got—and Jack said he's completed—the—secured the battery charge now.

Okay, and we're recording the time that that was complete. You have two lists there, one is LM to CM equipment transfer and the second list is the reverse. Request you scratch the last item on the first list, which is returning used bags to the CM.

Okay. We didn't have any of those, so that didn't pose any problem anyway.

Okay.

Aquarius, Houston.

Okay, Vance. Aquarius is back on.

Okay, Jack. Understand you completed securing the battery charge. Now if you are ready to copy, Jack, I would like to give you the two changes that we have to the powerup for the CM procedure. Over.

Okay. Stand by 1.

Okay.

Okay, Vance. You say you have some changes in the procedures that I used before to get telemetry and to check out the CSM system?

Yes, that's correct, Jack; they're pretty simple. About halfway through the procedure, we have a step on panel 3, which is POWER AMPL, HIGH; we'd like to change that to POWER AMPL, LOW.

Okay. Copy. POWER AMPL, LOW.

And the next change, Jack, is panel 275. Scratch the step “CB MAIN B, BAT B, close—BAT BUS B, close.”

Okay. You want to delete the step “CB MAIN B, BAT BUS B, close.”
