Spacelog Apollo 13

Well, it was varying lengths. Is it suppose to be a long-time PROCEED?

We think it may be, Jack. We think it may be 15 to 20 seconds, and our recommendation is that you PRO and hold it down for a good period of time, probably half a minute or more, and see if the DSKY blanks.

Okay. All right, I didn't hold it in that long. Maybe 2 or 3 seconds is the longest I held it.

Okay.

Okay, Jack just came down the tunnel again and said the computer's okay.

Okay. Good to hear it. And did you ever get that BAT C MAIN A reading for us?

I guess in the heat of the battle, I forgot to to give it to you, I guess. Stand by.

Okay.

BAT C current was 2 amps and BAT A voltage, 30.2.

Copy, 2 amps, 30.2. And that sounds good to us, Jim.

Aquarius, Houston.

Go ahead.

Okay. We'd like to have Jack verify that the PYROs in LOGIC are SAFE, and we'd like to remind him to do no further powerup of the CSM until EI minus 2 plus 30.

Roger. He reports that the PYROs are SAFE, and we're standing by for 02:30.

Okay. Real good.

Well, I can't say that this week hasn't been filled with excitement.

Well, James, if you can't take any better care of a spacecraft than that, we might not give you another one. Hey, Jim; Houston. You might ask Jack, while he's down there, to take a peek through the telescope and tell us whether he can see any stars. Over.

Okay.

Joe, Jack tells me that there's still a lot of particles floating around and he's—he can't pick out any constellation that he recognizes so far. But it might clear here in a little while.

Aquarius, Houston. Over.

Go ahead.

Okay. EECOM is looking at that battery amperage that you gave us awhile ago. He'd like to see it about a half an amp to an amp lower. Like you to ask Jack to just check the circuit breakers and switches that he's pulled in so far and make sure he doesn't have any extra loads on MAIN A; specifically, the FLOODLIGHT configuration, and his CAUTION AND WARNING circuit breakers, and his ESSENTIAL INSTRUMENTATION POWER circuit breakers. Over.

Okay.

Okay. Jack reported that he turned out all the floodlights.

Okay. Okay, we copy that. Like to have him check the amperage on there; see what you have now, and give us a voltage reading, too.

Okay, will do.

Go ahead.

Okay. I've been not reading any voltage at all on BAT C, and the amperage looks like about 2 amps, but that could be kind of noise-level stuff. I've got all the floodlights off and I—Can you think of anything—I could power down to lower MAIN A.

Okay. How about reading the voltage off of MAIN A?

Okay. Oh, this is Ken. Okay. Ken, it was 30.2.

Okay. We're checking out the floodlights we gave you. Actually, Jack, you ought to be able to go ahead and use the lights we gave you. There's no reason to sit in the dark. They're supposed to be coming off of MAIN B, and we're checking that now.

Okay. It's not bad down there. We're in—got plenty of light. But should I be reading the voltage on BAT C?

Jack, you should be reading BAT C voltage. That circuit breaker should be open.

Okay. Okay, can you think of anything else you want to get turned off to lighten load on MAIN A?

Okay. We're perusing that subject right now, Jack. It's really not that big a thing, just something we wanted to dress up.

Okay.

Okay, Aquarius; Houston.

Go ahead.

Say, Jim, as something to try, you might have Jack turn off the RING 1's AUTO coils, which are probably on MAIN A. Have him turn those off and take a look at the readings.

Okay.

Okay. Jack has turned off RING 1 that was on MAIN A, and he's still reading 30.2 volts.

Roger that, Jim. What's his amperage? Did he read that off?

I guess. He says it's down in the mud; it's less than 2 amps.

Down in the mud. Okay, understand that. Request he turn them back on and—Okay, Jim, that's the AUTO coils back on RING 1, MAIN A, and when you get that done, I'd like you to copy the entry pad.

Okay, Joe. Standing by to copy the entry pad.

Entry pad as follows: Mid-PAC, 000153, 000; 142:38:17, 178; minus 21.66, minus 165.37; 06.7; 36211, 6.51; 1168.9, 36292; 142:40:40; 00:28. Next four columns are N/A; D_O is 4.00, 02:04; 00:17, 03:22 08:14; 33, 353.1, 29.9. Zebra Libra, or something like that, Beta Libra is down 08.8, left 0.4; lift vector up; GDC entry alined, stars 31, 33. Roll 041, pitch, 045, yaw 024. EMS nonexit pattern to be used; maintain Moon-check attitude until moonset. and if all else is lost, the constant g entry is right—Roll is right.
