Vance Brand (CAPCOM)

Okay. In answer to the battery-charging questions, I calculate it should be fully charged at 12:35. Play that one, though, the same as the waste vent. If you want to do it earlier because you're turning in, why that's fine with us.

Fred Haise (LMP)

Okay, we'll continue on with a few other things we got to get done, and just before turning in, we'll check with you, and you can remind us then.

Jack Swigert (CMP)

Houston, Apollo 13. Give me a call when you're ready for E-memory dump.

Vance Brand (CAPCOM)

This is Houston, 13. You are weak. Please repeat.

Jack Swigert (CMP)

Okay, Vance, give me a call when you're ready for our E-memory dump.

Vance Brand (CAPCOM)

Okay, 13. We're not quite ready yet. We'll give you a call when we're ready.

Jack Swigert (CMP)

Okay, Vance. I understand you're ready.

Vance Brand (CAPCOM)

Negative, GUIDO isn't quite ready yet.

Jack Swigert (CMP)

Okay. I thought I heard you call us.

Vance Brand (CAPCOM)

But we're ready now, Jack, so GUIDO says he's ready to take it.

Jim Lovell (CDR)

Okay, Vance. Requesting clearance now to turn the vent valve back to CLOSE again, and also the battery charge off.

Vance Brand (CAPCOM)

Roger. That's fine with us, Jim. Proceed.

Vance Brand (CAPCOM)

We think the spacecraft's looking in good shape. Nobody has any comment down here before you hit the hay.

Jim Lovell (CDR)

Okay. Row do they think we stand on the way of consumables so far?

Vance Brand (CAPCOM)

You're looking in good shape in all respects—consumables-wise.

Jack Swigert (CMP)

Okay, go ahead, Vance.

Vance Brand (CAPCOM)

Just the last comment, Jack. Would you clear Hal, please, so he doesn't burn his lights out there tonight?

Jack Swigert (CMP)

No, I—I was just—I'll do that for you.

Vance Brand (CAPCOM)

And we'll see you in the morning, huh?

Jack Swigert (CMP)

Okay. It'll be just a minute or 2 yet. We have to finish up a couple more chores.

Jim Lovell (CDR)

What do you mean? It is morning.

Vance Brand (CAPCOM)

It's been a long day, huh?

Jim Lovell (CDR)

Yes, it sure was.

No contact for 10:22:29
Joe Kerwin (CAPCOM)

Good morning, 13. This is Houston. How are you?

Jim Lovell (CDR)

Read you loud and clear. We had a fairly good night's sleep.

Joe Kerwin (CAPCOM)

Okay. Real fine. At your leisure, you can give us radiation reports, I guess. We are getting a consumables update together for you, and a few other little details whenever you are ready to talk. About the only major thing on the spacecraft is that it's been getting farther away.

Jim Lovell (CDR)

Okay. Well, that's to be expected, I guess.

Fred Haise (LMP)

And we're starting to charge battery A, Houston.

Joe Kerwin (CAPCOM)

Roger on battery A, Fred. EECOM says battery B looks real good.

Jim Lovell (CDR)

Okay. For information, Fred was on COMM last night; and he was over in the left-hand seat, and if you want our radiation readings, we just goofed. We left them all in the suits which are now nicely tucked away. We are going to get out Jack's suit in an hour or so anyway, and we'll get his dosimeter out if you wanted to get the reading on that one.

Joe Kerwin (CAPCOM)

Okay. That will be satisfactory.

Joe Kerwin (CAPCOM)

And in exchange for that, the surgeon would like to have a rough number of hours each of you slept and a qualitative verb to describe whether it was good, fair, or poor.

Jim Lovell (CDR)

Okay, Houston. We had an average of around 5 or …

Joe Kerwin (CAPCOM)

Jim, Houston. Your COMM got pretty garbled there just as you started to talk.

Jim Lovell (CDR)

Okay. Houston, Apollo 13.

Joe Kerwin (CAPCOM)

Okay, 13. You're loud and clear again.

Jim Lovell (CDR)

We averaged about 5-1/2 hours' sleep apiece, and we are estimating that the sleep was good.

Joe Kerwin (CAPCOM)

Okay. Copy that. Let's see what else we have for you, Jim. Midcourse-2 looks like about 23 feet per second, approximately retrograde and on time. And it's holding real firm now. For your information, and you don't need to copy this down, because it's still pretty soft, but we have an S-IVB impact of about 8.57 south and about 33.9 west, which is a little west and a little south of the flight plan value. We have it at a GET of about 77 plus 51 which is just before AOS, and the LOI pads are a little bit late, and as I say, it's still pretty soft, and we'll be updating you with firm numbers.

Jim Lovell (CDR)

That's fine, Joe. Just as long as it doesn't hit Cone Crater.

Joe Kerwin (CAPCOM)

Okay. And I'll have a consumables update for you in a little while, and I have a small flight plan update for you sometime a little later on when you're ready to copy. There's no big deals in it.

Joe Kerwin (CAPCOM)

And, 13, Houston. We'd like to verify that you cycled the O2 cryo fans. We saw the H2, but we didn't see the O2 get stirred up.

Jack Swigert (CMP)

Yes, Joe. We did, and it kind of looked like we might have had a little stratification because right after we put them on, we had a CRYO PRESS light.

Joe Kerwin (CAPCOM)

Okay. EECOM told me that might happen, and he was right.

Jack Swigert (CMP)

Okay, Joe. We're ready to copy a flight plan update and your consumables.

Joe Kerwin (CAPCOM)

Okay, Jack. The flight plan update has a couple of items in it, and the first one we'd like to do is to update the Tephem values in the G&C checklist on page G/9-2. These are fairly small changes, but in case you need them, we'd like you to have the exact numbers. Over.

Jack Swigert (CMP)

Okay. Just a minute. I'll get it out.

Jack Swigert (CMP)

Joe, was that the G&C checklist, page 9-2?

Joe Kerwin (CAPCOM)

That's affirmative. G&C, page G/9-2.

Joe Kerwin (CAPCOM)

Okay. On that page in line 04, column B, change the number from 03366 to 05253. Over.

Joe Kerwin (CAPCOM)

Okay. And in line 05, column B, change from 11000 to 33661. Over.

Joe Kerwin (CAPCOM)

Okay. That's right. The only other thing I've got for you, Jack, is three additional questions for the booster systems debriefing, which is to take place at about 25 hours, and we thought we'd pass these questions up to you early so you can consider them. Over.

Jim Lovell (CDR)

Okay. We're ready to copy.

Joe Kerwin (CAPCOM)

Okay. The first extra is, and let me get the original question because this question says, “More specifically on item 2,” and item 2 says, “Were there any significant changes in the noise vibration level during the single stage of powered flight?” Specifically, describe your observations during the early S-II center engine out-off, and approximately 90 seconds prior to TLI cut-off, you reported a high vibration in the S-IVB. We'd like you to describe the buildup of this vibration and its behavior through cut-off. Over.

Jim Lovell (CDR)

Okay. Essentially, what you'd like us to talk about is vibration sequence during the early S-II cut-off of the center engine and also describe the vibrations that we encountered during the S-IVB TLI burn. Is that correct?

Joe Kerwin (CAPCOM)

That's it. Okay. The second extra question is for you, Jim, and it says, “Comparing this flight with your ride on Apollo 8, were there any significant differences in the powered flight environment?”

Jim Lovell (CDR)

Okay. We'll describe a comparison with 8 and 13 as far as powered flight goes.

Joe Kerwin (CAPCOM)

Roger. And the last additional question is what did the ORDEAL ball look like during TLI? As you know, we passed you an update to that setting, and we'd like to know whether it was riding right on zero or what during the burn. Over.

Jim Lovell (CDR)

Okay. Will do. We'll describe the ORDEAL ball.

Joe Kerwin (CAPCOM)

Okay. That's it, and that's the whole flight plan update. I have a consumables update now if you want to listen to that.

Jack Swigert (CMP)

Okay, Joe. We're ready to copy.

Joe Kerwin (CAPCOM)

Okay. At 23 hours the total RCS is 1121, quad A is 274, quad Bravo is 286, quad Charlie is 274, quad Delta is 287, and the cryos are as follows: H2 tank 1, 83 percent; H2 tank 2, 86 percent; O2 tank 1, 87 percent; O2 tank 2, 87 percent. Over.

Jack Swigert (CMP)

Okay, Joe. We got all those, and how do we compare them with where we should be in the time line?

Joe Kerwin (CAPCOM)

As I understand it, Jack, you're running slightly ahead of nominal in both those areas.

Joe Kerwin (CAPCOM)

And, 13, Houston. That's all the business I got right now. I have a little news and plan of the day for you, if you feel like listening to that a little later on.

Jim Lovell (CDR)

Just hold off a little bit there, Joe if you don't mind. …

Joe Kerwin (CAPCOM)

Stand by one, Jim. You're coming in garbled again.

Joe Kerwin (CAPCOM)

Okay, 13; Houston. Loud and clear again. Go ahead.

Jack Swigert (CMP)

Okay. Joe. On the news, Jim would like to hold off a little bit on that, and I want to make a request to FAO, if he will at sometime during the day, when we get a flight plan update with those activities we agreed to make optional during lunar orbit and the few activities we were going to delete, I think that I forgot and left that card back during the press of suiting, I left it in the suit room.

Joe Kerwin (CAPCOM)

Okay, Jack. I understand FAO's working on that and we'll have something for you later on.

Jack Swigert (CMP)

Okay. We're not in any hurry.

Joe Kerwin (CAPCOM)

Roger.
