Spacelog Apollo 13

Okay. In the third row, under COMM: DISPLAY, open; SE AUDIO, closed; VHF A TRANSMITTER, open—That's a change—VHF B RECEIVER, open; PRIMARY S-BAND, POWER AMPLIFIER, open; TRANSMITTER/RECEIVER, closed; S-BAND ANTENNA, open; PMP, closed; TV, open. Under ECS: DISPLAYS, open; GLYCOL PUMP SECONDARY, open; LOC PUMP, open; CABIN FAN CONTROL, open; CABIN REPRESS, closed; and all the next four closed also. Read back.

Okay. We have DISPLAY, open; SE AUDIO, closed; VHF A TRANSMITTER, open; VHF B RECEIVER, open; POWER AMP's going to be open; TRANSMITTER/ RECEIVER, closed; S-BAND ANTENNA, open; PMP, closed; TV, open; DISPLAY is open; next three are open; CABIN REPRESS, closed; and all the rest closed.

That's affirmative, Jim. And in row 4, under HEATERS, we want them all—Correction—we want all the QUAD HEATERS open. Correction—we want all the QUAD HEATERS closed.

All the —

We want DISPLAY, open; S-BAND ANTENNA, closed—to avoid a MASTER ALARM, CAMERA—SEQUENCE CAMERA, open; And under EPS, we want DISPLAYs, open; DC BUS VOLT, closed; INVERTER 2, open; ASCENT ECA, closed; ASCENT ECA CONTROL, open; DESCENT ECA, closed; DESCENT ECA CONTROL, closed; TRANSLUNAR BUS TIE, close; we want the CROSS TIE BUS, open; the BAL LOADS, closed; BAT FEED TIEs, closed. How do you read?

Okay. The four RCS HEATERS will be closed; DISPLAYS, open; S-BAND ANTENNA, closed; CAMERA SEQUENCE will be open; DISPLAY will be open; DC BUS VOLT will be closed; INVERTER 2 open; ASCENT ECA will he closed, but the ASCENT ECA CONTROL, open; DESCENT ECA, closed; DESCENT ECA CONTROL, closed; TRANSLUNAR BUS TIE, closed; and CROSS TIE BUS, open; and BALANCE LOADS, closed; and the BAT FEED TIEs, closed. I have one question, Jack. On panel—on the second line there under LIGHTING, why are we keeping: the FLOODS and TRACK closed? Or are they going to be open?

Negative. We have the, LIGHTING breakers all closed. Control the lighting with the switches and rheostats. Over.

Okay. We don't need the floodlights, I don't think, but we can do it that way, I guess.

And under row 4, under RCS SYSTEMS A/B-2, QUAD HEATERS, you notice that we've closed those circuit breakers, but what we want you to do is to—on panel 3, turn the RCS A/B-2 QUAD switches 1, 2, 3, and 4, off. Over.

And we're going to watch your quad temps for you, and when we need to warm them up a little bit, we'll tell you to throw those four switches on—on panel 3.

Okay. Now are we sure that this PTC mode is good enough so we don't … get crossed up later and get out of configuration.

Stand by 1 on that, Jim. Okay, Jim, as far as we can tell right now, the PTC looks as good as any PTC we've ever seen in a CSM, so we're going to go with what we've got.

Okay.

Okay, and if you turn over the page on Power 8, we have the spacecraft functions remaining to you. We've got low bit rate TM. However, we don't have any VHF. We have CWEA. We have GLYCOL PUMPS. We have SUIT FANS. We have CABIN REPRESS for you, and stand by in ATTITUDE CONTROL here. Okay, in ATTITUDE CONTROL, we'll have hardovers for uses in emergency, and for normal usage we want to have a 15-minute delay to get the heaters on to warm them up be before use. How do you read?

Okay. For emergency, we have the hardovers and for normal use it requires a 15-minute request to get the heaters on.

That's affirmative.

Okay, Jim, that concludes our powerdown procedure, and we're waiting for you to get with it.

Okay, Jack, we'll start. I sure hate to lose the PGNS. I sure hope that procedure for the midcourse is a good one.

It is.

You want me to help you here?

Yes, you can—Okay. First we power down, panel 11. All of them open.

Closed.

Yes.

Stand by for a MASTER ALARM. …

Okay.

Here it comes.

LTG. You just did it.

I'll give you this when I'm finished. After we go through this, then you can go through it again and doublecheck it.

Right.

Now, the flood lights are on, right? No, I kind of don't think we need them though, do you?

Okay. We'll do it right there.

Okay. And I'm closing the HEATERS on panel 4, QUAD 1 through 4, OFF.

Okay. It's time for you guys to get to bed and get Fred up.

(Laughter) I still have one question, Jack. I still think that—I still say that the—on the LIGHTING in our panel 16, the FLOOD lights and the TRACK should be open. We're not using them.

Do you have any argument about -

No problem, Jim. Go ahead and open them, TRACK and FLOOD, that's all right.

Okay, TRACK and FLOOD are OPEN.

Now, why don't you go through that, Jack, and make sure those —

Yes.

—

Okay, I'll take this.

Okay, Jack, my only other concern now is the CO₂ rise in the spacecraft. I guess you're keeping a handle on that?
