Spacelog Apollo 13

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.

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?

Yes, sir. Loud and clear.

Okay. It's perform CM—CSM RCS preheat, and could you say again all after?

Okay. I'm referring to the entry checklist, page E/1-5, steps 35 and 37.

Okay. Perform CSM RCS preheat per entry checklist, page 1-5, steps 35 and 37.

That's affirmative. Now back to panel 5: circuit breaker CAUTION AND WARNING, MAIN B, closed.

CB CAUTION AND WARNING, MAIN B, closed.

That's affirm. On panel 2: CAUTION AND WARNING POWER to 1.

Panel 2: CAUTION AND WARNING POWER to 1.

That was POWER to number 1, Jack.

CAUTION AND WARNING POWER to 1.

Okay. On panel 5: circuit breaker EPS SENSOR UNIT, DC BUS A and B, closed.

Okay, Ken. The COMM from you is awful weak—awful weak, I—I can't—it's CB EPS SENSOR UNIT. Say again, after that.

All right, Jack. That's CB EPS SENSOR UNIT, DC, that's Delta Charlie, BUS A and B, closed.

Okay. CB EPS SENSOR UNIT, DC BUS A and B, close. And I'll give you the volts and amps.

Okay, that's correct. Go ahead.

Okay. Volts are 39.1; amps, 1.5.

Okay. On panel 3: MAIN BUS A and B, go to RESET and leave it in the center.

Okay, panel 3—Stand by; got to change OMNI's.

Okay. MAIN BUS A and B, RESET, then center.

That's affirmative. Okay, now we're at EI minus 5 plus 05. And, as far as you're concerned, Jack, the command module is using this for information only. This will be the LM doing an Earth-terminator AGS alinement; and at the time of 5 plus 05 is the time they'll be going ahead and releasing their ball. And this will be covered in the LM checklist; it'll be uplinked after this one. At EI minus 5, we perform midcourse number 7. Over.

Okay. At EI minus 05:05, the LM is making an Earth-terminator aline; and at EI minus 05:00, we perform MCC-7.

That's correct. At the completion of midcourse 7, the LM will maneuver to a separation attitude. And this attitude will be sent up on one of the pads that you're going to get before all the sequence starts. And it'll be flown to the LM ball angles on that pad.

Okay. Understand.

All right. At EI minus 4 plus 40, we want to perform page 1-6, step 39 of the entry checklist.

Ken, I—I didn't get it. We had to change OMNI's again. Could you say it—the EI minus 4 dash—or 04:40, we do something.

Okay. And at that time, you'll want to perform step 39 of page E/1-6. Over.

Okay. Perform step 39 of entry checklist page E/1-6.

That's correct. Okay. The next is the command module RCS activation, and that's step 4-1 of page E/1-6.

Okay. The next is perform CSM—or CM RCS activation for step 4-1 of page E—E/1-6.

That's correct.

All right, Jack. The next is at EI minus 4 plus 30. We want to verify that the LM is configured for command module RCS hotfire.

Okay. Verify LM configure for RCS hotfire at EI minus 04:30.

That's correct. Now to panel 5: circuit breaker G&N IMU HEATER, MAIN B, closed.

Okay. Panel 5: CB G&N IMU HEATER, MAIN A and MAIN B, closed.

That's negative, Jack. That's MAIN B only.

Okay. MAIN B only.

I'm sorry; I lost you that time. Say it again.

Okay. Let's repeat it. Stand by. Cut out. We've really got a strange attitude, so this is why we are having the COMM problem. Panel 5: CB G&N IMU HEATER, MAIN B, closed.

That's affirmative. On panel 1: ROTATION CONTROL POWER, NORMAL. That's two of them, to AC/DC.

Okay, panel 1: RHC, NORMAL, two to AC/DC, two controllers.

That's correct. On panel 7: SCS, LOGIC POWER 2/3, ON.

SCS, LOGIC POWER 2/3, ON, panel 7.

That's affirm. Back to panel 2: RCS COMMAND, ON.

Panel 2: RCS COMMAND, ON.

That's correct. Now the command module RCS check per step 4 of page E/2-1.

Okay. Perform the command module RCS check per step 4, page 2-1.

That's correct. Okay, at this point, we want to lock the rotation hand controllers.

Okay. After that, lock both rotation hand controllers.

That's affirm. On panel 8: SEQUENTIAL, PYRO ARM, two to ARM.

Okay. Panel 8: set PYRO ARM, two, to ARM. Do I get a MSFN GO for that?

That's negative, Jack. We haven't powered up any of the downlink at this time. You'll be doing this and the command module RCS pressurization both by yourself.

Okay.

Okay. Now, the next event is going to be the separation of the service module, and these are some LM steps, but so that you will know what is going on, I'll read them to you. The LM will do a LM plus-X of one-half foot per second. Then you'll be hitting the CM SM SEP on and up, on their command. As soon as we are free of the service module, the LM will do another LM minus-X for 0.5 feet per second. This is called the push-pull maneuver. I think it was described this afternoon.

Yes, Ken. It was, I heard about it.

Okay. I just wanted you to know that's the sequence you're in. Okay. At the completion of that, we go back to panel 8, and it's SEQUENTIAL, PYRO ARM, both of them, to SAFE.

Okay. Panel 8: SEQ PYRO ARM, two, to SAFE.

Okay. And following this, we take SEQUENTIAL, LOGIC, two, to OFF.

Okay. LOGIC, two, to OFF.

I'm sorry, Jack. I'll have to ask you to repeat that.

Okay. Panel 8: SEQ LOGIC, two, to OFF. Are they ON now, Ken? I don't remember turning them—I guess that's part of one of the other sequences, huh? That we turned them ON?

That's affirm. The reason we're turning the logic off, Jack, is a power savings. So we'll be turning them off, and I'll be getting them back on when we go to get off of the LM; and then turn them back off, then we'll be turning them on prior to entry. Just so you know what's coming.

Okay, real fine.

Okay. Then following this, the LM will pitch up to acquire the Moon—Excuse me, they're going to pitch up and acquire the service module and photograph, and they'll be using the ACA for rotations from now on. And you may see the LM out of window number 5 at the same time they pitch up to acquire it.
