Vance Brand (CAPCOM)

Roger, You're coming in a little weak. Have a recommended roll rate for this PTC, if you could copy.

Vance Brand (CAPCOM)

Okay. Recommend that you put in R1 the following: 03750, and that should give you exactly a rate of 0.3 degrees per second. Over.

Jack Swigert (CMP)

Okay. Enter 03750. Is plus or minus our choice?

Vance Brand (CAPCOM)

Roger. The same direction you rolled the last time, which I believe is plus.

Jack Swigert (CMP)

Hey, Vance, would you monitor our rates and kind of give an idea of when you think they're stable enough to start PTC.

Vance Brand (CAPCOM)

Roger, Jack. We'll take a look and let you know as soon as they look stable enough.

Jack Swigert (CMP)

Okay. I've got quads A and B disabled here.

Jack Swigert (CMP)

Have they come up with an idea of how much fuel I used on the docking and also the P23 session at 5 hours or 6 hours.

Vance Brand (CAPCOM)

I think we can give you something. Stand by a minute.

Vance Brand (CAPCOM)

Okay. It's looking good so far as RCS consumables are concerned, Jack. You're standing about 20 pounds above the curve right now. Looking at the TD&E, you expended 65 pounds or—Stand by—55 pounds, correction on that.

Vance Brand (CAPCOM)

And 14 pounds on P23s. You used a little more out of quad A than out of the others.

Jack Swigert (CMP)

Hey, could you say again the TD&E fuel? We've got a different—we all heard different things.

Vance Brand (CAPCOM)

I said 65 and then corrected that to 55 pounds.

Vance Brand (CAPCOM)

Okay, Jim. Your rates look good. It's okay to start the roll again, if you'd like.

Fred Haise (LMP)

Hello, Houston; Apollo 13.

Fred Haise (LMP)

Okay. Ready for a little count here, Vance, and I'll shoot another picture. We found the Earth again.

Vance Brand (CAPCOM)

Okay. We'll be standing by, Fred.

Fred Haise (LMP)

Okay. Stand by for a mark on another picture.

Vance Brand (CAPCOM)

Okay. Standing by, Fred.

Vance Brand (CAPCOM)

Jim, Houston here. Two items: first of all, your PTC is looking very good and it should carry you through the night; second point, have a procedure to give you, if you're ready to copy. We'd like to set three bits in the computer, and I'll explain why.

Fred Haise (LMP)

Go ahead, Vance, we're ready to copy.

Vance Brand (CAPCOM)

Okay. The procedure is as follows: VERB 25, NOUN 07, ENTER; 1331, ENTER; 7, ENTER; and ENTER. Explanation as follows. During the P23s, there was one time when VERB 37 was entered into the computer at about 16 seconds after the OPTICS ZERO switch was flicked to ZERO. This is a very uncommon anomaly in that, if you do this during—0.4-second interval at around 16 seconds after you zero the optics, some OPT-mode bits are reset; and this would mean that, if you had a OCDU fail, it wouldn't be indicated; so all this procedure is doing is setting these three bits back again where they should be.

Fred Haise (LMP)

Okay, Vance, and I guess I'll try to be slower on that VERB 37.

Vance Brand (CAPCOM)

Yes. Actually slower or faster, either one, I guess. Well, yes, slower. It's a very unusual thing to have that happen.

Fred Haise (LMP)

Okay. And, Houston, stand by for a mark on another picture.

Fred Haise (LMP)

Okay, Vance; we've completed that procedure, and let me know if everything was okay.

Vance Brand (CAPCOM)

Okay, thank you. We'll let you know if anything isn't okay. I'm sure it's good now.

Fred Haise (LMP)

Tell GNC and GUIDO thanks a lot for keeping good track of me, there.

Vance Brand (CAPCOM)

Roger. They're right on the ball.

Vance Brand (CAPCOM)

And, 13, Houston. If you would like, we can let you know about every 2 minutes before the Earth should be coming into your window. We think we've got it pegged down pretty well now, and you won't have to look for it so much. You want that?

Fred Haise (LMP)

Yes. That would be fine, Vance.

Vance Brand (CAPCOM)

And, 13, Houston. GUIDO says the bits are reset—rather, are set.

Vance Brand (CAPCOM)

It's time for Fred to start looking for the Earth, should be coming by in about a couple of minutes.

Jim Lovell (CDR)

Okay. He's got his head out there right now.

Fred Haise (LMP)

Yes. You've got that pretty well pegged, man. There it be.

Vance Brand (CAPCOM)

Doesn't that give you confidence?

Fred Haise (LMP)

Yes. I guess so. In a minute, you're going to hear my kitchen timer ding, and that also says the Earth is there.

Fred Haise (LMP)

Okay. Stand … countdown.

Vance Brand (CAPCOM)

Apollo 13, Houston. Over.

Vance Brand (CAPCOM)

Roger. We're enjoying Fred's music there.

Fred Haise (LMP)

Yes, I kind of like it too, Vance.

Vance Brand (CAPCOM)

Yes, we didn't hear much of it, though.

Jack Swigert (CMP)

Okay, Vance, we did another EMS null bias test and the—it went from 100.0 to 101.8 in 100 seconds.

Vance Brand (CAPCOM)

Jack, like to verify, was that 100 to 100.8 or 101.8?

Jack Swigert (CMP)

It was plus 100 to plus 101.8.

Vance Brand (CAPCOM)

The Earth's coming up in the window again in 1 to 2 minutes.

Jack Swigert (CMP)

He's got it. You're right again.

Jack Swigert (CMP)

Okay, stand by for a mark here.

Jack Swigert (CMP)

Okay, ready? 3, 2, 1 -

Vance Brand (CAPCOM)

Apollo 13, Houston. We have a CSM state vector to send you. Request P00 and ACCEPT at your convenience.

Jack Swigert (CMP)

Okay, Vance. There's P00 and ACCEPT.

Vance Brand (CAPCOM)

Okay, it's coming up.

Vance Brand (CAPCOM)

13, the computer is yours again.

Jack Swigert (CMP)

Okay, going back to BLOCK.

Fred Haise (LMP)

Key moment The crew take some photographs of Earth: Looks like picture-taking time again.

Vance Brand (CAPCOM)

Okay, Earth should be coming into view.

Jack Swigert (CMP)

Okay. Stand by, Vance. 3, 2, 1 -

Vance Brand (CAPCOM)

Earth starting to look pretty small now?

Jack Swigert (CMP)

Well, looking at here, Vance, it's hard to be convinced it's even the Earth. All we see is water and clouds.

Vance Brand (CAPCOM)

Well, I guess that's what we want. We want pictures of weather, right, clouds.

Jack Swigert (CMP)

Yes, about half of it's covered with clouds.

Vance Brand (CAPCOM)

This is Houston. Go ahead.

Jack Swigert (CMP)

Okay, Van. Ready to copy in the torquing angles of the P52 option 3?

Vance Brand (CAPCOM)

That's affirm—that's affirm, but stand by.

Vance Brand (CAPCOM)

Okay. We've got them. Go ahead with the torquing, Jack.

Jack Swigert (CMP)

Okay. That was stars 20 and 27 and star-angle difference is five balls, and the time at torquing would be 10 hours 40 minutes 15 seconds.

Vance Brand (CAPCOM)

1 hour 40 minutes and 15 seconds; 20 and 27, stars; and five balls. Roger.

Vance Brand (CAPCOM)

Time to look out your window for us again.

Vance Brand (CAPCOM)

Jim, we're coming up on a handover between sites. You might lose COMM momentarily.

Jim Lovell (CDR)

Okay. Understand handover, we might lose the COMM.

Vance Brand (CAPCOM)

You should have the Earth coming into view here shortly.

Fred Haise (LMP)

We got a new CAP COMM now.

Jim Lovell (CDR)

Negative, Houston. Say again.
