Spacelog Apollo 13

Okay. I'll stay this mode, if it's all right, so we won't be hot miked.

Aquarius, Houston. You're cleared to open the POWER AMPLIFIER circuit breaker and go to LOW BIT RATE, leaving the POWER AMP switch in PRIMARY.

Houston, Aquarius.

Go ahead, Aquarius.

About how far out are we now, Jack?

Okay, Aquarius. You're 150 000 miles and you're coming in at 4500 feet a second. That's from the Earth.

Okay. We're at 100—Yes. 150 K, 4500 feet a second.

And, Aquarius, how much TTCA control did you have to do in the burn?

How much—What was that, Jack?

How much control of the TTCA did you have to do during the burn?

I wasn't noticing Jim too much. I'd say I put in maybe about six or seven inputs. I don't think it ever got off more than a couple of needle widths.

Roger, Fred. Thank you.

I think it's probably the same for Jim. I wasn't noticing his input but the—his needle was hanging in there pretty good.

Aquarius, Houston. How do you read?

I read you loud and clear, Jack.

Okay, Jack. What's your status, who's sleeping, and who's working?

Well, right now we're all three kind of working. Do you have any recommendations?

Yes, looks like to us from here that you and Fred ought to get some sleep, and that you ought to eat in about 6 hours. And that the Skipper ought to go to bed about 113 hours.

Okay.

I've got some other information. We shouldn't have some good dope on your trajectory for about 2 hours. Looked like to us that the burn was real good, however, and we're taking a close look at it, and we'll get back with you on that in about 2 hours from now. Another thing that we're expecting to have happen is that the SHe tank is going to reach its burst limit. The earliest time we predict this will happen will be at 107 hours on about 25 minutes. And the latest probable time is at 110 hours, and this is supposed to be a nonpropulsive vent, but you might hear it and you might see something.

Okay. That's good news. We were wondering about that. And I'll relay all the other information you gave me.

Okay. And if the SHe tank does burst during this time frame before we get trajectory info, why, that will delay our trajectory info somewhat. Your consumables, your water is now good through 152 hours.

Jack, wait a minute. Let me copy some of this down.

Aquarius, Houston. Sorry about that but there's too much background noise to read you. I think we'll have to wait until you come up on a new antenna. Over.

Okay, Aquarius. Go ahead now. I think I can hear you.

Okay. Okay, Jack. I was going to say, as luck would have it, the command module picked this time to start venting again, so I probably won't be able to get a good hack out of stars out of the telescope.

Okay. Thank you. And if you can think of it, when the time comes up, when you're not venting how about remembering to take a look through them and give us a word?

Houston, Aquarius.

Go ahead. Over.

Aquarius, Houston. Did you call?

Yes, Jack. I just got a question. How long are you predicting our command module canisters to last in here?

Okay, Jack. We've got 14 cartridges that'll last 157 hours, plus we've got the LM primary cartridge with 23 hours, and we've got two PLSS cartridges with 7 hours apiece.

Okay. I was just curious as to how much time we've got out of these two cartridges.

Stand by 1. I'll get a prediction on that. By the way, I hope you're keeping track of the ones you've used and the ones you've not.

Yes, right now, we have numbers 7 and 8 in the LM here.
