Spacelog Apollo 13

Wait until I get PTC going first, Vance, then we'll give it to you.

Okay, Vance. We're P00 and ACCEPT. The computer's yours.

Roger. Here it comes.

You know, somehow, everytime I do a set of P23s, you guys uplink me a state vector. I don't think I do too well.

No —

I could get a complex.

No. You know—you know how the FIDOs are. They like to load in their own data, no matter what.

But our state vectors take into account the waste water dumps.

Yes, that's -

Apollo 13, Houston. It's your computer again.

Okay. Going to BLOCK.

And as a matter of interest, understand that the downrange comparison between the MCC and the computer is within 35000 feet, and that's on the last sighting, which people think is pretty good.

Okay. Maybe that gives us a little more confidence that if we had to do P23s on the way home, we'd make it.

Apollo 13, Houston.

Go ahead, Houston.

Just info on your PTC, Jim. It's looking very good. Just—excursions in pitch and yaw are very low.

Okay, thank you. And we're going to change another lithium hydroxide canister now.

Okay.

And, Vance. Has FIDO come up with any observations on the trajectory?

Well, a minute ago, he said that to tell you that he was pacified now after your past comments on his trajectory and so forth, and he hadn't seen any waste water dumps or anything and he's pretty happy.

Okay. I just wondered if we're going to need any more midcourse.

He says, seriously, it's looking probably like you won't have any more.

Hey, that's real fine.

FIDOs never guarantee anything, however.

Houston, 13. I have the onboard read-out, if you're ready to copy.

Roger. Go ahead.

Okay. BAT C 37, PYRO BAT A 37, PYRO BAT B 37, RCS A 97 percent, B 97 percent, C 96 percent, D 97 percent.

Apollo 13, Houston.

Go ahead, Vance.

Jim, just an item for you and Fred to be thinking about in case you haven't been briefed on this, something that's now being talked about a little bit. These conservative people would like to have you read the SHe tank pressure when you go into the LM for the LM familiarization at 58 hours. If there's no midcourse-3, and it looks like there's a good chance that there will not be, why, they might want to move the LM familiarization up from 58 to 55 hours. Over.

Okay. If we don't have a midcourse-3, then we'll probably move LM FAM up to 55 hours, in which case we'll go in there and read SHe tank pressure.

Roger. Along with the other FAM stuff, and it's not certain that we want to do this, it's just being talked about, so this is just the information for you.

Okay. This is beginning to sound like the SIM that we ran not too long ago.

Okay. Houston, 13.

This is Houston. Go ahead.

Okay, Vance. Our LM/CM DELTA-P is 0.9.

Roger. 0.9.

Apollo 13, Houston.

Go ahead, Vance.

Are you guys hacking into your presleep checklist yet?

Oh, we just finished eating and cleaning up a bit afterwards. Jim's going around collecting debris off of all the inlet hoses. And, I guess you might say we're kind of thinking about getting ready to go to sleep.

You couldn't ask for anything more than that. Just so it isn't so fast you —

No, it's a lot—a lot better. I remember from 8 when they didn't hardly ever get to look at either one.

That's right. They were tumbling about another axis, weren't they.

Yes.

It's pretty cloudy down there tonight. About the only land I can see again is a portion of Australia and Korea and looks like a part of China. Just about clouds covering everything else.

Can you still see that clearly with the naked eye, or do you have to look through a glass?

I can see Australia with the naked eye and the China landmass, but I—It took the monocular to pull out the Korean Peninsula.

How about the Moon? Is it looking very big yet?

No, not really. Bigger, but we've got a ways to go.

I understand that they're estimating your pericynthion—lunar pericynthion is now 62 miles.

Well, that's not bad.

That's supposed to be just right.

Yes.

Okay, Houston; 13.

Go ahead, Jack.

Okay. We're into the presleep checklist now. As far as the crew status report, as far as medication goes, we've had no medication. And we're all feeling really good. I've given you the onboard readouts. Jim is chlorinating the potable water now. I'm ready for an E-memory dump whenever you're ready.

Stand by 1 on the E-memory dump, Jack. I think we'll be ready in about a minute.

Okay.

And EECOM says that as soon as you stir your cryos, request you go back to AUTO on that one tank.

Okay. We'll do that.

Hello, 13; Houston. We're ready to take your E-memory dump.

Apollo 13, Houston. Were you trying to call?

Go ahead, Houston.

Houston, 13.

Apollo 13, Houston. We thought you were trying to call. Were you?

I don't believe so unless we inadvertently hit the microphone button.

Must have been some other guy trying to call, Jack.

Just trying to get some words in, eh Jack?

Roger. We saw the downvoice subperiod come on. We thought maybe you were trying to call. Sorry. I hope we haven't disturbed you and from where I sit, it looks like you're running a rest home up there. Good night.

We're all going to bed now just after we play the last rendition of “With Our Eyes on the Stars.”

(Music)

Okay, Jim. And we'd like you to check your S-BAND NORMAL voice switch, OFF.

Houston, 13. We'll be off COMM; so if you need us, send a crew alert, please.

Okay, Jim. If we need you, we'll send a crew alert, and we'd like to know who's got the duty tonight on the BIOMED. Is that you?

Yes. I'll be on the BIOMED.

Okay. We copy, and you're spoiling my good record of two watches without saying anything.

Just want to keep you busy, Jack.

You're waking me up.

Houston, Houston, Apollo 13. Over.

Good morning, 13. You're early.

Ah so. I just thought I'd be waking up. And we are awake and getting the spacecraft shipshape. …

Roger. Spacecraft is in real good shape as far as we're concerned, Jim. We're bored to tears down here. We do have a few little items for you, like a P37 update and a couple of flight plan updates. But there's no rush about them. Over.

Okay. Gig us again in a few minutes. We're breaking out some food, and we'll copy them then.

Okay. And the surgeon will be ready for your sleep report whenever you get that together.

Righto. If he's listening, LMP had a solid 9 hours of sleep; I couldn't wake him up this morning. The CMP had 6 hours, and the commander about 5 intermittent.

Okay —
