Spacelog Apollo 13

Houston, Aquarius.

Aquarius, Houston. Go.

Volts, 39.3; amps, 1.2 zip.

Okay. We copy 39.3 and 1.20. And, Jim, I've got one more item for information for you. At—In about 45 minutes or so, you will get an H₂O quantity caution light on the descent tank. We expect this. It occurs at 16 percent. And it's no problem, because we intend to run the tank dry just for drill. To reset the—the light, on panel 2, just set the O₂ H₂O QUANTITY MONITOR to the CAUTION/WARNING RESET position and the light will go away. Over.

Okay. I understand. We're going to get a H₂O warning light here shortly, and I'll reset it.

Houston, Apollo 13.

Aquarius, Houston; go ahead.

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.

Roger. Jim, we noticed you just went to AUTO and back to CLOSE on the SUIT RELIEF valve. Is everything okay?

We didn't do that intentionally. Stand by.

Okay, maybe you didn't. Incidentally, you're less than 24 hours to go.

Roger. What happened was, our lithium hydroxide device here got caught in the suit relief valve. It is closed now. That's where you want it, right?

Okay.

Okay.

And, Joe, just a reminder; now that you mention it—that it's less than 24 hours to go, what I'd like to do, and I have aboard all the procedures that you are working up; so I can run through them with the crew, and make sure that we get all our signals straight.

Roger that, Jim. We are trying to get the procedures finished and up to you as quickly as we can. They exist. What's going on now is the guys are running them in the CMS/LMS, integrate, to make darn sure that the attitudes are correct and the time line is nice and relaxed and all that good stuff. And they won't be finished that run for another few hours. However, we expect to have an overall time line and a sequence of events for you before that time, and we'll start with the procedures as soon as they get ready. Over.

Okay. That's good. I think … ought to go back to the original procedures we have on board and modify them as we have the time to.

Okay, Jim. Roger. We're going to do that to the maximum extent possible. And it looks reasonably feasible. To begin with in the command module we're going to have to send you some separate sequences for powering it up a little bit at a time. The closer we get to entry the more we get on the checklist. By the time we're about at EI minus 45 we're on the checklist all the way.

Okay.

And just as a reminder, don't forget our stowage problem. We—We still have to do quite a bit of stowage of the drogue and probe in the LM, and, et cetera.

Roger that. We've got a team working on that, and incidentally, one of the information items that they want to know is which lithium hydroxide containers in the command module are empty. They just want to know that for weight and balance—and there's no rush about it —

Aquarius, Houston.

Go ahead, Aquarius.

Another note of interest to the crew systems people—Tell them that they don't have to bother putting the refrigerator onboard. I just brought out some hot dogs, and they're practically frozen.

Aquarius, Houston.

Go ahead.

Okay. We'd like another volt, amp reading, Jim.

Okay. Stand by, Joe.

Roger.

Houston, Aquarius.

Go ahead, Jim.

Volt 39.4, amp 1.23.

Aquarius, Houston. Over.

Go ahead.

Guess what.

What?

Your volts and amps time, Jim.

That goes like the Amos and Andy show.

Houston, Aquarius. Guess what.

Aquarius, Houston. What? Over.

39.4, 1.27.

Are you really going up there, and looking at them?

That's what the meters say.

Aquarius, Houston. Over.

Go ahead.

Okay, Jim. We show the SUIT CIRCUIT RELIEF valve is back in the AUTO position, and we'd like to have it off for good scrubbing. Over.

Have you seen … out there?

Okay. Thank you, Jim.

… up there—about … of the scrubbers. If you think …

Roger. No sweat. Jim, in a few minutes I'm going to be coming at you with the—with the overall time line for tomorrow morning. You might want to think about taking a few notes, although we don't have detailed procedures for you at this time. Maybe you want to have Fred or Jack listen. Over.

Right. We're all set to copy.

Aquarius, Houston. Over.
