Spacelog Apollo 13

Okay.

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.

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.

That's affirmative. Circuit breaker EPS SENSOR SIGNAL, MAIN A and MAIN B, closed.

EPS SENSOR SIGNAL, MAIN A and MAIN B, closed.

Okay. On panel 275: circuit breaker MAIN A, BATTERY C, closed.

Okay, Ken. Wait on that one here. I'm just about to lose you here. Just—I've got to change OMNIs.

Okay.

Okay. Could you give me that one again, please.

All right. On panel 275: circuit breaker MAIN A, BATTERY C, closed.

Okay. MAIN A, BAT B, closed on 275.

That's MAIN A, BATTERY C, Charlie.

MAIN A, BAT C, Charlie.

That's affirm. No—Negative on battery Bravo.

Okay. Negative on battery Bravo. That's MAIN A, BAT Charlie, closed.

Okay. Good. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.

Would you say that one again, Ken?

All right. On panel 276: circuit breaker INSTRUMENTATION POWER CONTROL, 3 and 4, open.

Okay. Panel 276: CB INSTRUMENTATION POWER CONTROL, 3 and 4, open.

That's affirmative. Okay. Panel 5: circuit breaker CENTRAL INSTRUMENTATION POWER, MAIN B, closed.

Okay. On panel 5: …

Okay. I'm sorry, Jack. Would you read that again, please?

Okay. On panel 5: CB CENTRAL INSTRUMENTATION POWER, MAIN B, closed.

Okay. That's correct. PRIMARY EVAPORATE WATER CONTROL valve to AUTO.

This is on 382?

That's affirmative.

Wha—Wha -

Okay, Jack. We want to put the PRIMARY and the SECONDARY EVAPORATED WATER CONTROL valves to AUTO.

Okay.

And, Jack, can you give us a readout on BAT B and the charger current?

Okay, Ken. That was the PRIMARY and SECONDARY H₂O CONTROL valves to AUTO on 382.

That's affirmative, and did you copy about the readout on the battery and charger?

Yes. Jim's on his way up.

Okay. Thank you. All right, the next little step after your water control valves is to perform the CSM RCS preheat. We'll do that on page E/1-5, steps 35 and 37.

Okay, Ken. We're having a problem with the COMM. You read now?
