Spacelog Apollo 13

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.

Well, I hope you had a good meal.

It wasn't too bad.

(Music)

Sounds like you guys are really living it up up there. All that music, food. I didn't say drink.

Yes, it is pretty nice. Not bad at all. You're right; you didn't say it. This PTC we're in is a pretty—pretty nice merry-go-round, Vance. Every 10 minutes alternately I get to look at the Earth and the Moon.

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.
