Spacelog Apollo 13

Okay. Good deal.

So, I guess we can keep FIDO happy with no overboard dumps.

Roger that.

Yes, that brings up one more possibility, Joe.

Say again, Fred.

Brings up another possibility. Now that we've got all of that stowed into the bags and the condensate can, we could probably blow all of that through the PLSS …, I wonder how the sublimator would work on waste water.

It might work if we had to do it, Fred. Right now we're looking at a comfortable excess of water through the sublimator. We were talking among ourselves this morning about having you try out the PLSS to ascent tank water-transfer situation and we decided not to do it, not to recommend it, because we figure it'd take us 30 hours to empty one of the ascent tanks, which you have to do in order to get PLSS water to it, and we'd rather use the descent water and we don't think we've gotten any sweat. Over.

Okay, Joe. I don't think there's any question about it from the plumbing standpoint that we could do that if we had to.

And, how do you read, Joe?

Read you pretty good, Fred. Go ahead.

I think our PTC wobble is growing worse. The Earth now is really up to the top of the window. I have to get way down almost to the floorboards to view it. Conversely, the Moon is way down at the bottom of the window.

Okay.

A lot more wobble.

Roger —

Far more wobble than I noticed on my previous watch.

Okay. Copied that, Fred. And our thermal people will be looking at it. One of the things we're talking about relative to the midcourse correction is we'd like not to do it before the SHe tank goes, if it's going to go, just so it won't give us a problem reestablishing PTC. And right now our people think that the burst disk will pop around 106 hours.

Aquarius, Houston. Over.

Go ahead.

Okay, Fred. Since you went ahead and used the PLSS condensate container, we got the procedure in for using it. I'm not going to read it up to you except that it cautions a little bit about shaking it too much or about filling it too full, because they feel that if you do that the vent valve might unseat and the bag might leak a little bit. Over.

Okay. We haven't removed it from its stowage spot. We just left it right in place, and just—he mated the tank at the end of the cable and hooked right into that.

Understand. That's satisfactory and recommended that you leave it in the stowage spot. That should help the situation.

Roger.

We got a—we got another flow shower going on outside. Particles, seeing them vented against the service module. Jack thinks it may be an H₂ vent. …

Okay. Copy that. What window are you looking at it out of, Fred?

Out the LM docking window.

The docking window. Roger that. Somebody just handed me your latest consumables status report, and you're using between 11 to 12 amps an hour real steady, and it looks real good.

Joe, what are you showing for GET now?

I think you wanted the GET, Jack, and the present GET is 96 hours 21 minutes. Over.

Okay, thank you.

Okay.

And Jack, Houston. For your information, FIDO tells me that we are in the Earth's sphere of influence and we're starting to accelerate.

I thought it was about time we crossed. Thank you.

Roger.

We're on our way back home.

There's something that puzzles me, Joe. Vance mentioned yesterday that the planned entry is a CMC-guided entry, so I'm kind of curious as how are we going to get the alinement.

Did you say how we're going to get guidance? Over.

No. How are we going to get a platform alinement?

Okay. We got a number of interesting ideas on that and the latest one I've heard is to power up the LM platform and aline it, and aline the CM platform to it.

Okay. That sounds good.

Okay. And we're working out detailed procedures on that, Jack.

Aquarius, Houston. Over.

Go ahead, Joe.

Okay. We are taking our final look at the mid-course procedures and we have a question as to the present position of one of the switches. The switch is the AGS STATUS switch on panel 6. We'd just like to know where it's at.

Okay. Stand by.

Okay, Joe. The AGS STATUS switch is OFF.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

Okay, Vance. I just heard a little thump, sounded like down in the descent stage, and I saw a new shower of snow flakes come up that looked like they were emitted from down that way. We've already decided though—I wonder what the SUPERCRIT pressure looked like now.

Okay. Understand you saw a thump in the descent stage and a few snow flakes. We'll take a look down here, see if we see anything.

Aquarius, Houston.

Aquarius, Houston.

Go ahead.

Fred, we don't see anything wrong. For example, your SHe appears to be okay as far as we can see. The thing we don't have data on, is the … tank down there.

Okay. And I doubt if it would have been that anyway.

Okay. While we have you on the horn —

We're still getting -

Roger. Still getting it.

Go ahead.

While you're on the horn, be advised our calculations show you might be running out of potable water in the CSM pretty soon. Also, that you might start to have hydrogen tank venting in the CSM and a question. Next time Jack looks through the sextant and telescope, we'd like him to see how it looks. Do you have anything on the optics, any specks or anything?
