Spacelog Apollo 13

I just relieved the watch; just thought I'd find out how things are going.

Okay, Jim. Good morning; and understand you relieved the watch, and the rest was kind of blurry. Did you have any questions?

No questions, Joe. Just …

Aquarius, Houston. Over.

Go ahead.

Okay, Jim. It's about time, at your convenience, for another volts and amps reading on the command module. For your information, we put 6 amp-hours back in the battery already and we've got about 14 to go. It's looking real good, and I also just got the word that the entry weather tomorrow is looking better all the time. Really looks great.

That's good. When I went to bed last night, … a lot of rain …

Couldn't copy that, Jim. Sorry.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

Roger. 39.2 on the volts; 1.4 on the amps.

39.2 and 1.4. Thank you.

Aquarius, Houston.

Go ahead, Joe.

Roger. Just for your information, in case it happened when you were off watch, the master caution circuit breaker is still pulled, and we're seeing the—the malfunction indication on the descent battery now, but all the parameters still look just as good as ever, and that's just for information.

Okay. I see the battery light flickering now.

Okay. Recommend you ignore it.

Aquarius, Houston. Over.

Go ahead, Houston.

Jim, it's volts and amps time again, at your convenience.

Okay.

Houston, Aquarius.

Go ahead, Aquarius.

Aquarius, Houston. If you gave me those readings, I didn't copy them. Over.

Houston, Aquarius. Do you read?

Aquarius, Houston. Okay; go ahead.

Volts, 39.3; amps, 1.25.

Okay. Copied 39.3 and 1.25. Jim, did Jack tell you what your trajectory looks like? Over.

Haven't got up to … on it. How about giving me a rundown?

Okay. We are looking at a vacuum perigee right now of 23.6; flight path angle of minus 6.25; and if we decide we want to trim that up, we're looking at a midcourse of about 2 feet per second. Your consumables, of course, are getting better all the time; we've got 163 hours of water, 230 hours of oxygen, and 172 hours worth of electrical power. Over.

That sounds good.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. We would like to get another check from you on the propellant tank temperatures, as we did yesterday. And the procedure is to, on panel 16, circuit breaker PROPELLANT, DISPLAY/ENGINE, OVERRIDE/LOGIC to close. Then go to your display and read the tank 1 and tank 2 temperatures for us, and then open the circuit breaker again. Over.

Okay. I'm closing now—the DISPLAY/ENGINE, OVERRIDE/LOGIC.

Roger.

Okay. And the reaction control temperatures are 65 in A and 65 in B.

Okay, Jim. We'd like the descent tank temperatures, too. Over.

67; oxidizer is 63; descent tank 1 … is 64; the oxidizer is … Did you copy? Over.

Hello, Houston. Did you copy the—the DPS display temperatures?

Jim, I copied 63 and 64, which I think were the descent 1 temps, and that's all I got.

Okay. I'll go over it again. I'm on descent 1, now and fuel is about 64, and oxidizer is 65, and I'll go to descent 2 —

Okay. Thank you very much —

— our descent 2. Okay. I've got descent 2 now right up on 67 and 66.

Roger. We copy that, and once again we'd like to get the volts and amps check in the command module. Over.

Okay, Joe, we got the WATER warning light.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. The experts would like another volt and amp reading.

Okay; have them stand by.

Houston, Aquarius.

Aquarius, Houston; go ahead.

Voltage is 39.3, amps 1.26.

Copy 39.3 and 1.26.

Houston, Aquarius.

Aquarius, Houston; go.

Joe, you might pass to our friends in Crew Systems that lunar boots make great footwarmers.

I guess you need them up there, too. Is—is anybody sleeping in the command module right now, Jim?

Negative, Joe. It's just too cold in there. I got Fred stashed over here to my left. He's asleep and Jack's …

Roger.

You can eliminate the chilldown procedure for reentry.

Aquarius, this is Earth. Over.

Go ahead, Earth; Aquarius here.

Roger. Earth is here, also; and, Jim, it is time for another one of those volt/amp checks. For your information, we've got that battery back up to 30 amp-hours now. Over.

Hey, that sounds great. Jack's gone up to check it.

Roger.

Aquarius, Earth.

Go ahead.

You know, I think Aquarius is …

We've got garble now, Jim; I'm sorry.

I said Aquarius …

Roger.

Houston, Aquarius.

Go ahead.

Voltage 39.3, amps 1.26.

Okay. Copy that, Jim.

Jim, Houston. Have you guys put on any extra clothes to try and ward off the nip of Jack Frost? Over.

Well, the lunar boots and two pair of underwear, and everyone is … crawl into their sleep restraints.

Yes.

We're a little reluctant to break out the suits.

Yes, that's understandable. You can always use them if you have to. I guess it's pretty hard to get extra coveralls on, huh?

Well, Joe, I didn't think we had any extra inflight garments aboard, but we're going to check right now.

Aquarius, Houston.
