Spacelog Apollo 13

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.

Okay. That's the panel 8 floodlights. Now we're going to take panel 5 and put the FLOODLIGHT rheostat to FLOOD and the LEB, that's panel 100, FLOODLIGHTS are also going to FIXED. And the purpose of this is to balance up buses A and B.

Okay. Panel 5; FLOODLIGHTS; you want the rheostat on. Panel 100, FLOODLIGHTS; you want FIXED.

That's affirmative. Okay. On panel 8: circuit breakers EMS, MAIN A and MAIN B, that's two, open.

Okay. Panel 8: EMS MAIN A and MAIN B, open.

Okay. On panel 250: circuit breaker BATTERY A POWER ENTRY and POSTLANDING, closed.

Okay. Panel 250: CB BAT A POWER ENTRY and POSTLANDING, closed.

Okay. The same for circuit breaker BATTERY B POWER ENTRY and POSTLANDING.

Okay. BATTERY B POWER ENTRY and POSTLANDING, closed.

Okay. And add BATTERY C POWER ENTRY and POSTLANDING.

BATTERY C POWER ENTRY and POSTLANDING, closed.

Okay. That's correct. On panel 5: circuit breaker BAT CHARGE, BATTERY A CHARGE, closed.

Okay. Panel 5: CB BAT CHARGE, BAT A, close.

Okay. And the same for circuit breaker for BATTERY CHARGE, BAT B/CHARGE, closed.

Okay, BAT CHARGER, BAT B, closed.

All right. Like to take MAIN BUS TIES, two of them, on and up. That's probably a verify.

MAIN BUS TIES A/C and B/C, on, verify.

That's correct. Circuit breaker BATTERY RELAY BUS, BATTERY A and B, closed.

Okay. CB BAT RELAY BUS, BAT A, and BAT RELAY BUS, BAT B, closed.
