Spacelog Apollo 13

Okay. I was kind of holding off on this. We're dumping a little waste water now.

Okay, Vance. We've got quad C and B disabled.

Apollo 13, Houston.

Go ahead.

It may be awhile before your rates are settled down. We're still observing fairly high rates and deadbanding. Over.

Apollo 13, Houston.

Go ahead, Vance.

Okay. We've got about three items. First one is, all of your P23 batch—two marks have been evaluated and—Hey, congratulations. Looks real good; they're very happy with it. You're down to 4 arc-minutes on the substellar-point aspect of it, and that's the first thing to mention. The second is, unless you see a need, I don't see any need for you to read back the information we gave you on the solo book and so forth. Do you concur?

Roger. I think I got it. I remembered a lot of it, and so I think with what you gave me and what I remember, I'm pretty sure we got it right.

Okay, and the third item, I was just about to call that your rates were stabilized to start the PTC, but it looks like they're jiggling around again from a dump, so we'll stand by some more.

Okay.

No secrets around here.

Say again. Hey, that's right.

I said there's no secrets around here.

Yes. Big Brother is watching.

13 —

I can just see EECOM telling FIDO.

Yes. You really have to watch that pair, all right. By the way, we have a maneuver pad for you, a fly-by pad, whenever you're ready to copy.

Okay. Stand by.

Go ahead, Vance.

Our pad as follows: fly-by, SPS/G&N; 63385; plus 0.97, minus 0.23; 072:24:33.08; plus 0212.7, minus 0141.7, minus 0254.8; 148, 316, 050; NA, plus 0022.5; 0360.9, 0:53, 0356.3; 33, 352.7, 15.0; NA, NA, NA; minus 23.26, minus 165.00; 1147.7, 36172; 166:54:02; set stars 31, 23; roll is 288, pitch 205, yaw 034; no ullage; SPS docked; and LM weight, 33499.

Roger. That's correct. Want to verify under NOUN 81 that DELTA-V_X is plus 02127. You cut out right there.

Roger. DELTA-V_X is 02127.

Roger. And your rates are low. Looks like you can start the PTC.

Okay. In work.

Okay. And when the computer is available, request P00 and ACCEPT and we'll ship you your state vector.

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.

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.

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.
