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.

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.

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.

Well, it's got a new name now, because it is about 30 degrees cooler.

Roger. Returning to the deep freeze —

— Hey, Vance. One thing that I wanted to ask you—is on the stowage list where you have us putting the black-and-white TV camera on top of A-7 in an A … decontamination bag, I was wondering if it would be possible or if you—there would be any problem in putting it into B-6 along with the two 70-millimeter Hasselblad cameras?

Jack, I don't think there'll be any problem, if you can get it in, but let us get—work that and get back with you. Okay?

All right. I was just thinking. I'm trying to get as much weight as possible down there in that LEB. We have no SRCs and then our waste tank is—you know—rather depleted. I think it's about down to 40 percent or so. So I'm trying to get as much L over D as I can, and any heavy items we can get down there, I'd be greatly appreciative of you bringing it to our attention.

Okay. We copy that, and we owe you an answer on your last question.

Okay. And I'm in work, going to give you some telemetry.

Aquarius, Houston. We're receiving CSM data now.

Aquarius, Houston.

Say again, Vance.

Fred, we just lost data on Aquar—on Jack. Would you have him select best OMNI, please?

Aquarius, Houston.

All right. Go ahead.

Fred, we have enough data; recommend that Jack take off the TM and power back down again, using his backout procedure. Just let us know when he does it.

Okay.

And, after that, we'll start the battery charge, and we'll have to know when he starts that.

Okay. He's starting to back out now. Just out of curiosity, what—did you all get a readout on what the cabin temp was up there?

Yes, we're getting 45 to 46 degrees.

Now you see why we call it the refrigerator.

Yes, it's kind of a cold winter day up there, isn't it? Is it snowing in the command module yet?

Is it what, Vance?

Is it snowing in there yet?

Oh, snowing. No—no, not quite. The windows are in pretty bad shape, and I guess the service module—we'll be trying to shoot out of the LM window, because every window in the command module is just covered with water droplets. It's going to take a lot of scrubbing to get those cleared off.

Roger. Understand. Pete says to tell you that you'll have some time on the beach in Samoa to thaw out after this cold experience.

Hey, that sounds great.

Vance, have you all thought about what cameras you wanted to use? Right now, we've got configured a Hasselblad with a 250, and I've got the lunar-surface number 1 Hasselblad, and I've got the lunar surface sequence camera, also, rigged and ready to go. Did you have any other druthers about the …

You are referring to the photography of the service module, is that right?

That's right.

We have some procedures in work, and I've seen them, Fred. I think pretty soon we'll be shooting them up to you to specify which cameras and settings. But that—that sounds pretty close.

Okay, you might let them know that, if they hadn't thought of it, that we got this lunar-surface sequence camera on board which has its own battery pack setup, and to shoot quite a few pictures with, and that could also be used for this.

Roger. I know we are planning to use that camera, among others.

Okay, Houston; Aquarius. Jack has backed out of powering up the CM, and now he's proceeding to restart battery charge on BAT A.

Okay. And we are charging battery A now.

Roger. Charging battery A, Fred.

And, Fred, request now first reading of voltage—BAT A voltage and charger current. Over.

Okay, Vance. I can give it to you. I read it right after I started it. BAT A voltage was 39.4 and the current had jumped up to 1.4.
