Spacelog Apollo 13

Jim, we—you were able to get those voltage—BAT A voltage and current readings?

Oh, yes. Fred's—Fred's up there now.

Okay. And we're ready to read you the first checklist installment. This will—What we're going to readup is going to be a LM time line, a CSM time line, and checklist changes to conform with these. And right now I have the first installment of the CSM time line ready to read up. Over.

Okay, Jack. I'm going to get—Vance, I'm going to get Jack on the line for that; and so stand by.

Okay. And he'll need a lot of paper.

Okay. Volts are 39.5; amps, 1.24. Stand by.

Okay. We got it.

Aquarius, Houston.

Okay, Vance. I'm on and ready to copy.

Aquarius, Houston.

Okay, Vance. Go ahead.

Okay, Jack. Do you have any of that CM water—bagged water, left? Over.

Negative. I went up and tried to repressurize the surge tank and get another shot of water, and was able to repressurize the surge tank okay, but there was no water that came out of the water tank.

Yes. We understand that there isn't any more in the potable tank, but we understood that you had put some water from that tank into bags, and I wondered if any of the bags were left.

Negative.

Okay, Jack. Ready to copy?

Okay, Vance. Ready to copy.

Okay. Start at EI minus 6-1/2 hours. You're going to re—get LM pads and CSM pads, and I don't know if you want to copy them or not. This is something I can just read off to you. Over. Without you copying unless you especially want it.

Okay.

Okay. LM pad, SM jettison —

Okay. Go ahead; read which ones we're going to get.

Okay. I'll read them fast first here so you get a general idea. LM pad, service module JETT attitude, Moon viewing attitude, Sun viewing attitude, and LM JETT attitude. The CM pads are coarse aline angles for LM attitudes during Moon and Sun sightings, coarse aline angles for entry REFSMMAT, and CMC angles on entry REFSMMAT for LM JETT. Moon viewing, and entry. Okay. That—That's general pad information. If you want, I'll read it slowly so you can copy it all down; otherwise, I'll go ahead.

I got—I was trying to copy it as you were reading it, Vance. The LM pads are service module jettison attitude, Moon viewing attitude, Sun viewing attitude, and LM jettison attitude. Is that correct?

That's correct. Okay. I'll read the CM pads now, slowly. Coarse aline angles for LM attitudes during Moon and Sun sightings.

Okay. The next coarse aline angles for entry REFSMMAT. Okay. The next, CMC angles on entry REFSMMAT for (1) LM JETT, (2) Moon viewing, (3) entry. Okay. I'll stand by until you read that back.

Okay. The CSM pads will be coarse aline angles for LM attitudes during Moon and Sun sightings. Coarse aline angles for entry REFSMMAT. CMC—CMC angles on entry REFSMMAT for (1) LM jettison, (2) Moon viewing, (3) entry.

Okay. That's correct.

Okay, Jack. Going to hold up 1. All the hordes of people that devised this procedure are going to be coming into the room in a minute, and they'd like to hold up until everybody can listen in.

Get that, Jack?

Okay, Vance. We're ready to go.

Okay. We lost you there briefly while you were in an attitude where we couldn't receive you. Jack, we'd like to hold off for about 5 minutes. We have some more people coming in to listen to this, and it took a lot of people to devise this procedure, and a few people have been testing it out, so we'd like to have them all on hand while we give you the rest.

Okay.

How's the temperature up there, Jack? You guys chopping wood to keep warm?

Deke, it's about 51, I think, or 50 in the LM, and it's about—I don't know—45 or little bit less in the command module.

Oh, it's a nice fall day, huh?

Okay, Vance. While we're waiting, do you have there also what I can expect ground to uplink me?

We'll have that, Jack, but—Stand by for that.

Okay.

Jack, probably—probably the thing to do is to give you all of the checklist, and it will include things like this. Then we'll have a big question and answer session afterwards, if that's okay by you.

Okay, Vance. While we're waiting, just for your information, the command module has been stowed per your checklist with the exception of the two Hasselblad cameras.

Roger. Got that, Jack.

And the LM is pretty well stowed with the exception when we have yet to bring in the probe and the drogue.

Roger. Got that.

Relative to your water situation, Jack, we're going to have a pretty good hack on the LM here in the next few hours, and we anticipate letting you fill your own tanks before we transfer over, so you should be in reasonably good shape there.

Okay. We have a number of juice bags all out and ready to go, and we tried to get the water out of the command module about 20 minutes ago and found out that the command module's potable tank was empty. So we have no bags made up now, so we're dependent on LM water, PLSS water.

Okay, Deke. All the windows in the command module are heavily coated with water right now. So I don't know what kind of pictures we'll get out of them, but I'm going to try and clean them off and do the best I can with the 250-millimeter lens on the Hasselblad.

Roger. That's why we have the top priority stuff in the LM. We figure you've got a much better chance of getting it through there.

Aquarius, Houston.

Are you ready to send it up, Vance?

Jack, before we start reading the procedure, we'd like—We find that BAT A is topped off and in great shape. Like to switch over and top off BAT B some more. Give it 2 more hours of charging. Have about a seven- or eight-step procedure here to give you, if you want to copy that. We're switching before we start recording the entry procedures.

Okay. Stand by and let me get out my other checklist.

Okay, Vance. Ready to copy.

Okay. This is the procedure for charging BAT Baker. Panel 3; BAT CHARGE, OFF; panel 5; MAIN BUS TIE, BAT A/C to A/C; CB BAT CHARGER, BAT A CHARGE, open; CB BAT CHARGER, BAT B CHARGE, close. Panel 250; CB BAT B POWER ENTRY and POSTLANDING, close. Panel 5; MAIN BUS TIE, BAT B/C, to OFF; Panel 3; BAT CHARGE to B. This is a DELTA for the first battery charging procedure; you'll give me the backout procedure in a couple hours.

That's affirm.

Okay. I'll put it in work right now, then come back and stand by to copy the rest of—well, I—not the rest—everything.

Everything is right.

Okay, Vance. I put BAT Baker on charge; I don't think it quite had stabilized. It was reading 1.1 amps, 39.6 volts when I left up there.

Okay. We got that.

Okay. I guess now is as good a time to start as any.

Just a second, Jack.

Aquarius, Houston.

Okay, Vance. You're kind of weak, but readable.

Jack, we're going to need readings on the BAT volt and charger amps about every 10 or 15 minutes for a while, so is there somebody else that can be reading them out while you're copying? Over.

Yes. Jim will take a run up there. Fred-o is sleeping right now. We're trying to get some sleep here, and Jim'll run up and take a look at voltage and current whenever you call.

Okay.

Houston, Aquarius.

Go ahead, Aquarius.

Vance, we've got to realize that we've got to establish a work-rest cycle up here, so we just can't wait around here to just read procedures all the time up to the burn. We've got to get them up here, look at them, and then we've got to get the people to sleep. So take that into consideration when you get ready to send up the pads.

I know, Jim. We're very conscious of that. We—we should be ready to go in about 5 minutes. That's all I can say. Stand by.

Aquarius, Houston.

Okay, Vance. We're ready to go.

Okay. We need a—Sorry (laughter). We need a readout. Volts and amps.

Okay. In work.

And, might as well bring the COMM up to a higher fidelity for this long period of checklist reading. That requires, panel 16: CB PRIMARY S-BAND POWER AMP, closed.

Okay, PRIMARY S-BAND POWER AMP closed now. How do you read?

Okay. And next step, panel 12: S-BAND FUNCTION to VOICE and RANGING FUNCTION to RANGING.

Okay, Vance. The S-BAND FUNCTION is at VOICE and the RANGING switch was at RANGING.

Okay. That makes it so we can hear you better, Jack.

Okay. Can we—Since the first part of it, you're just going to read and I'm going to copy and we're going to have a question and answer period later, can we get started?

Okay. Procedure's coming back in again. Multicopies for distribution. And Ken's back. He's a local expert on this now, so we'll turn you over to him and he'll read it off.

Okay. Stand by. I'll give you volts and amps. Okay. The voltage is 39.1; amps, 1.75.

Okay.

Hello, Aquarius; Houston. How do you read?

Okay. Very good, Ken.

Okay. Let me take it from the top here. Just—there might be some overlap, but to make sure we're all on the same signal. We're starting off with a set of time line procedures that are going to give us—end up with the normal entry checklist. There will be some checklist changes into the book, but the bulk of what I have for you is the time line stuff. And it starts at 6 hours and 30 minutes prior to EI and assumes that we're getting LM power to MAIN B in the command module. I think you already have the numbers for the LM pads and the command module pads; I mean the types of pads we'll be giving you. And if you have a question on what they'll be doing or what they're for, I can go over those now or when we get through.

Okay. Yes, I'll make a little note there, and we'll discuss it when we get everything copied, huh?

All right. And the first item, then, after you get ready to start this checklist, is to install lithium hydroxide canisters and to stow ORDEAL. On panel 8, we want to turn the FLOODLIGHTS to FIXED.

Okay. Wait a minute. You're going too fast, here.

Okay. I'll tell you. I'll go line at a time and wait for your verification before I go on to the next one. I have panel 8, FLOODLIGHTS, FIXED,

Okay. Install LiOH canisters, stow ORDEAL, FLOODLIGHTS, FIXED.
