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?

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

Okay.

Okay. I'm ready now.

Okay. We're predicting that you still have more water than you need. And one thing we'd like for you to do is when you're going to sleep up there in the command module take a look through the optics and see if you can see any stars.

Okay, Jack, I will do. Jim and I were able to spot constellations from the windows of the LM when there's no venting taking place. Could you give me some time on these consumables, what you're predicting they're good for? I think you started to give them times, didn't you, or was I just hearing things.

We started to give you some times. We think we might be able to give you some better ones pretty soon. But it looks like your water is good through 154 hours, and you've got takusan O₂ through 272 hours, plenty of lithium hydroxide, and your amp-hours ought to be good through 199 or 200 hours. Over.

Okay; good. Copy that.

We expect that your water rate is going to drop off and at the time, DELTA will go up to 160—165 hours quite shortly. Another thing we're interested in is what's your status on rest and medication.

Okay. None of us, I know of, had any medications, and right now as far as rest, I suppose we're no tireder than normally in this situation. I'm going to relay the work-sleep cycle.

Okay. And don't forget to look through the optics when you go up in the command module.

(Laughter) Okay. I'll do that.

Jack, as luck would have it, we just now started to vent a little from the command module …

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.
