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.

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. 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?
