Spacelog Apollo 13

Okay. Go ahead, TK.

Yes, sir. Understand you have a question.

Yes. I guess I didn't understand what the letter and the number was behind some of these photo targets.

Okay —

Does that refer to the pages?

Yes, sir. That's the map. Each fold is lettered in the lower—or upper right-hand corner if you work your way from east to west and the charts are labeled D, E, and F and the solo stuff will all be the D and E, and they change with the plane change 1. That's the time they change the two maps.

Okay. I got it. Thank you.

Yes, sir. You're doing good work, hey.

Well, I had a good prime crewman that taught me all I know.

Don't run out.

Hey, when FIDO gets a good hack on our trajectory, will you let us know?

How long you willing to wait?

He's looking at his calendar, if that means anything.

(Laughter) All right.

Okay. I'm back at the attitude here, and I'll wait for rates to damps and you let me know when we're stable again.

13, Houston.

Go ahead, Vance.

Roger. Just a reminder you have to disable Charlie and Delta here as you've done in the past. Over.

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.

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.
