Joe Kerwin (CAPCOM)

13, Houston. Wonder if you could zoom in on that S-IVB for us a little bit?

Joe Kerwin (CAPCOM)

Yes, yes. More like that. That's nice. It's off our screen to the right, now.

Joe Kerwin (CAPCOM)

Oh, that's very nice, very nice.

Jack Swigert (CMP)

Okay, Joe. Is EECOM monitoring the O2 FLOW HIGH light again? We haven't yet started the venting yet.

Joe Kerwin (CAPCOM)

Okay. Stand by. I'll check.

Joe Kerwin (CAPCOM)

Jack, your cabin REGs are still making up, but you're GO to open the waste management vent again at this time, and we'll delta the time to close it by the appropriate amount for you.

Jack Swigert (CMP)

Okay. Real fine. Well, we'll wait till the S-IVB does its maneuver here.

Fred Haise (LMP)

Okay, Joe. We just had a momentary dropoff in signal strength again there.

Joe Kerwin (CAPCOM)

Roger, Fred. We had an LOS for a minute and we lost our TV picture. It looks like—yes, we Just got it back. It looks great again.

Joe Kerwin (CAPCOM)

13, Houston. You might stop the f-stop down one more notch, if you got any left.

Joe Kerwin (CAPCOM)

And, 13, Houston. We'll be commanding the evasive maneuver in about 17 seconds.

Jack Swigert (CMP)

Okay, Joe. We can see it start to move. However, it doesn't seem to be a lot of debris or vapor coming out of it.

Joe Kerwin (CAPCOM)

Roger that, Jack. Booster says that's great. He says the booster's doing its thing normally. Concur. We don't see much on the television at all.

Joe Kerwin (CAPCOM)

And, Apollo 13, Houston. We'd like to change the S-band and antenna configuration. Like you to go OMNI Delta. Like you to go MANUAL mode on the high gain with pitch of minus 60 and yaw of 90. Over.

Fred Haise (LMP)

Okay. You want us to OMNI Delta and MANUAL on the high gain to minus 60 and plus 90. Is that correct?

Jack Swigert (CMP)

Okay, Houston. How much longer would you like the television?

Joe Kerwin (CAPCOM)

Stand by on that. We'll get a word.

Joe Kerwin (CAPCOM)

Okay, 13; this is Houston. You can turn the TV off anytime you're ready. We've enjoyed the show.

Joe Kerwin (CAPCOM)

13, Houston. Before you secure the TV, we'd like to know whether that was in maximum zoom, just for information.

Fred Haise (LMP)

That's affirm. Jim had it in MAX zoom.

Joe Kerwin (CAPCOM)

Okay. Good deal. That was a real good picture.

Joe Kerwin (CAPCOM)

And, 13, Houston. The APS evasive maneuver appeared to be nominal. The LOX dump time is now 4 plus 39 plus 20, about 3 minutes late.

Jack Swigert (CMP)

Okay, Joe. We are right now opening the WASTE STOWAGE VENT.

Jack Swigert (CMP)

Okay, Houston. We are charging battery B.

Joe Kerwin (CAPCOM)

Roger, 13. We see it. Looks good.

Joe Kerwin (CAPCOM)

Apollo 13, Houston. Request OMNI Alfa now. Over.

John Young (CAPCOM)

Roger. They are having trouble verifying that the high gain is doing its thing. Like to verify that the pitch is minus 10, the Y is plus 350, you're in WIDE BEAM WIDTH and AUTO.

Fred Haise (LMP)

Okay. Minus 10 pitch, plus 350 yaw, and WIDE BEAM WIDTH and going into AUTO. You want HIGH GAIN, John?

Fred Haise (LMP)

Okay. Here, it's coming at you.

Fred Haise (LMP)

All right, Houston; 13.

Fred Haise (LMP)

Is the S-IVB doing something different now?

Joe Kerwin (CAPCOM)

Well, I don't know. It should be—let's see, it should have started the LOX dump at least quite a while ago. I guess that's complete. Why do you ask, Fred?

Fred Haise (LMP)

I'm looking out window 5 at what I think is the S-IVB, and I'm seeing what looks to be double plumes, going in two very narrow bands maybe about 3 degrees that are streaming out from it. And then there is a less dense band that covers maybe a 40-degree swath through the sky that continues out, also, in two directions.

Jack Swigert (CMP)

Hey, Joe, what it looks like, kind of, is if you pull up behind a guy that's pulling a contrail, and you get in his contrail, like he's going away from you—there's a long contrail -

Joe Kerwin (CAPCOM)

Okay; stand by. Let me see what Frank's got to say about that.

Fred Haise (LMP)

Except we're between—Looks like we're between two contrails, one guy above and one below.

Fred Haise (LMP)

It's a very pretty sight.

Joe Kerwin (CAPCOM)

Okay, 13; Houston. The booster says that the propulsive dump is concluded; he now has the nonpropulsive vents open and what you see is a normal phenomenon and it should go on for another 5 minutes or so.

Joe Kerwin (CAPCOM)

And, while I've got you, 13, at your convenience, we'd like to have the results of the EMS bias tests that you did pre-TLI and pre-SEP.

Jack Swigert (CMP)

Okay, Joe. The TLI—the DELTA-V no bias test prior to TLI, we had a 0.8, and post-TLI, it was 1.0.

Joe Kerwin (CAPCOM)

Okay, Jack. Copy that. Thank you very much. Incidentally, as your tracking gets better and better, the size of MCC-2 is getting lower and lower and figures to be somewhere between 20 and 30 feet per second now.

Joe Kerwin (CAPCOM)

Okay. We have a PTC REFSMMAT ready, if you're ready to go P00 and ACCEPT, we'll stick it in there.

Jack Swigert (CMP)

Okay. I'm P00 and ACCEPT, Joe.

Joe Kerwin (CAPCOM)

Apollo 13, Houston. We'll have a handover in half a minute or so. You may get a momentary loss of strength.

Joe Kerwin (CAPCOM)

Apollo 13, Houston. The computer is yours. Over.

Fred Haise (LMP)

Okay, Houston. Do you copy 13's torquing angles on the P52?

Joe Kerwin (CAPCOM)

13, Houston. Leave them up just a second, and we'll get them down.

Joe Kerwin (CAPCOM)

13, Houston. Okay. We got them.

Jim Lovell (CDR)

Okay. The time of torquing was 5 hours 30 minutes and 40 seconds.

Jim Lovell (CDR)

Hello, Houston; Apollo 13.

Jim Lovell (CDR)

Okay. I just got all hooked up to get in my COMM system here, and I just wanted to check out. I've got my suit stowed, a few other odds and ends done, and I'm back in business again.

Joe Kerwin (CAPCOM)

Okay. Good deal. We're kind of hanging loose down here. I've got a lift-off plus 15 pad. There's no hurry to read it up, so let us know when you're ready.

Jim Lovell (CDR)

Okay, Houston. Go ahead with the pad.

Joe Kerwin (CAPCOM)

Okay, Jim. Lift-off plus 15 pad: GETI 015:00, DELTA-VT 5622, longitude minus 165, and GET 400K 047:04. Over.

Jim Lovell (CDR)

Okay, Houston. Lift-off plus 15: GETI 015:00, 5622, minus 165, 047:04. Is that correct?

Joe Kerwin (CAPCOM)

Roger. We'd like to have the ATTITUDE SET switch back to GDC, if you're finished with your aline. It gives GNC down here a telemetry problem.

Jack Swigert (CMP)

I'm just going to give them one more aline here.

Joe Kerwin (CAPCOM)

Roger. Would you please verify or tell us what S-band antenna configuration you're in, please?

Joe Kerwin (CAPCOM)

Roger. Stand by a minute, Jim. Our signal strength is getting a little low. We may have a recommendation.

Joe Kerwin (CAPCOM)

13, Houston. Are you in MANUAL or AUTO in HIGH GAIN?

Jim Lovell (CDR)

Stand by. We're in AUTO TRACK, Joe, and HIGH GAIN.

Jack Swigert (CMP)

Hello, Houston; Apollo 13. Over.

Jack Swigert (CMP)

Hey, were you copying my P23 results?

Joe Kerwin (CAPCOM)

That's affirmative, Jack. We followed you through the whole thing. You're ahead of schedule.

Jim Lovell (CDR)

And, Joe, we confirmed there is no midcourse-1. Over.

Joe Kerwin (CAPCOM)

That is affirmative as far as I know. Let's get a final check on it, Jim.

Jim Lovell (CDR)

Okay. Because we're standing by. We want to do a fuel cell purge and a waste water dump.

Joe Kerwin (CAPCOM)

Okay, Jim. We confirm there will be no midcourse-1.

Jim Lovell (CDR)

Okay. It sounds good.

Joe Kerwin (CAPCOM)

And, 13, Houston. You can go ahead with the purge and dump at your discretion.

Jim Lovell (CDR)

Roger, Houston. What we're going to do is, we're going to get rid of Fred's suit here. Fred's suit has been right in the commander's slot here for the last half hour. So we're going to try and get it stowed.

Jim Lovell (CDR)

You did a pretty good job.

Joe Kerwin (CAPCOM)

Apollo 13, Houston. We'll have a handover in about 1 minute.

Jim Lovell (CDR)

Hello, Houston. Apollo 13.

Joe Kerwin (CAPCOM)

Roger, Jim. We'll have a handover from Hawaii to Goldstone in about 30 seconds.

Joe Kerwin (CAPCOM)

We'll be handing over from Hawaii to Goldstone in a few seconds. You may get a temporary loss of COMM.

Jim Lovell (CDR)

Okay, Houston. We've got a whole bunch of noise, too.

Jack Swigert (CMP)

Hey, Joe. Do you want to dump waste water down to 25 percent. Is that right?

Jack Swigert (CMP)

Do you know we're also purging fuel cells O2 now.

Jack Swigert (CMP)

Okay, Houston. The fuel cell purge and waste water dump are complete.

Vance Brand (CAPCOM)

Roger, Apollo 13. And this is your relief CAP COMM shift on now.

Jim Lovell (CDR)

Well, good evening, Vance.

Jack Swigert (CMP)

Boy, you sure made it back fast.

Vance Brand (CAPCOM)

Yes. You guys had a beautiful launch, there. Really nice.

Jack Swigert (CMP)

Could you follow it all the way up, Vance?

Vance Brand (CAPCOM)

No, I didn't see staging. It was too hazy for that, but we could see it for a few miles anyway.

Jack Swigert (CMP)

I'll tell you, it's sure an interesting ride.

Jim Lovell (CDR)

Roger. We're at that stage now where we're going to take some Earth weather photography. If you're standing by, I have the camera aimed at the Earth right now, and I'll give you a mark when I take this first picture.

Vance Brand (CAPCOM)

Roger. We copy, Jim. We'll be standing by for the mark.

Jim Lovell (CDR)

Okay, Houston. 3, 2, 1 -

Vance Brand (CAPCOM)

And Apollo 13, Houston. Over.

Vance Brand (CAPCOM)

For the PTC, recommend that you disable quads A and B. Over.

Jim Lovell (CDR)

Okay. Disable quads A and B, will do; and soon as Jack gets finished thrashing around, we'll be going to that PTC mode.

Jim Lovell (CDR)

Okay, Houston. We're starting PTC. We're disabling quads A and B now.

Vance Brand (CAPCOM)

Roger, Apollo 13. Houston copies.

Vance Brand (CAPCOM)

Apollo 13, Houston. Over.

Vance Brand (CAPCOM)

Jim, we'd like to verify that the high gain is secured, that the S-BAND antenna is on OMNI, and OMNI B should be the right antenna. Over.

Jim Lovell (CDR)

Okay. You want the high gain secured and you want the OMNI on OMNI Charlie, huh? Or Baker?

Vance Brand (CAPCOM)

That's affirm. And this'll be maintained in the PTC.

Vance Brand (CAPCOM)

And the high gain angles for stowage—or for stowing—are pitch minus 52, yaw 270.

Jim Lovell (CDR)

Stand by for another Earth weather picture. I'll give you a mark.

Vance Brand (CAPCOM)

Houston here. Your rates look very stable. It looks like your rates are damped out completely here. As far as we can see, it would be alright to start the PTC.

Jim Lovell (CDR)

Okay. We'll give it a try.

Fred Haise (LMP)

Hello, Houston. This is 13. How do you read?

Vance Brand (CAPCOM)

Hello, 13; Houston. Loud and clear. 13, Houston is reading loud and clear. How do you read?

Fred Haise (LMP)

Okay. And do you have any estimate, Vance, on how long we'll be charging battery B?

Vance Brand (CAPCOM)

We'll be charging for 4-1/2 to 5 hours yet, Jim.

Vance Brand (CAPCOM)

Fred, recommend that, when your window comes around facing the Earth again, that you catch another one of those pictures, and at the same time, you should probably start PTC again. We might have sent a confusing bit of info up to you. The “disable two quads” only applies to an early step in the procedure. We didn't mean that for the latter part of the procedure where we have the statement “enable all jets.” Over.

Vance Brand (CAPCOM)

Apollo 13, Houston. Go ahead.

Jack Swigert (CMP)

Vance, Fred said that you had some more information about PTC and a different way of establishing it or something, huh?

Vance Brand (CAPCOM)

Roger. Referring to the procedure on G/8-2, if you have that open, I'll tell you what we had to give you.

Jack Swigert (CMP)

Okay. Stand by and I'll get it out.

Vance Brand (CAPCOM)

Okay. On checklist G/8-2 under step 5, there's a statement, “disable all jets on two adjacent quads,” and that's what we were referring to when we called up saying “disable quads A and B.” So that's all fine; however, going down now to step 7 where it says “enable all jets,” we hoped that you didn't think we meant leave A and B disabled there. In that case, it's as written. All jets should be enabled. Over.

Jack Swigert (CMP)

Okay. Our checklist has “all jets” scratched out, and it says “enable couples on all axes.” So what we'll do is—we'll reestablish this thing and come down to that step 7, and we'll enable all jets. That means enable quads A and B. Is that right?

Vance Brand (CAPCOM)

That's affirm. You'll have A, B, C, and D enabled for step 7.

Jack Swigert (CMP)

Okay, real fine. I'll start on it now.

Vance Brand (CAPCOM)

Okay. Understand you're going to reestablish it.

Fred Haise (LMP)

And Vance, on that picture, I was all set to shoot it just a little before you called, and the Earth hasn't showed up in the window yet. I don't know if we got too far off the bellyband or what.

Vance Brand (CAPCOM)

Roger. On the photo, you'll probably have to reestablish the attitude for PTC and then whenever it comes into the window again, why we'll just be standing by for the photo.
