Spacelog Apollo 13

Okay. Real good, Jack. Our S-band signal strength has been fluctuating. Does it seem to be going all right up there in the AUTO TRACK mode?

Yes. Right now; yes, it's dropped off to about the 70-percent point, Joe, and it was before up about 85.

Okay.

And, Houston, do you have a TV picture?

Not at the moment, Jim. We had a garbled one there for a few seconds, and we don't have one at this moment.

Okay. I can see the S-IVB now out the hatch window and it's —

Okay, Jim. Suddenly we have a very good picture.

Okay.

And, Houston, I can see the gold shroud around the IU, and it looks that it's all intact.

Roger, Jim. We copy that. Incidentally, the APS evasive maneuver will be about 4 minutes late. It'll be at about 04 plus 18.

Roger.

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

Okay.

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

Oh, that's very nice, very nice.

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

Okay. Stand by. I'll check.

13, Houston.

Go ahead.

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.

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

Okay.

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

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.

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

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

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.

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.

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.

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

That's affirmative.

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

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

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

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

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

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

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.

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

Okay, Jack. We copy.

Okay, Houston. We are charging battery B.

Apollo 13, Houston.

Go ahead, Joe.

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.

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

That's affirm.

All right, Houston; 13.

13, Houston. Go ahead.

Is the S-IVB doing something different now?

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?

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.

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 -

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

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

Roger.

It's a very pretty sight.

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.

Okay.

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.

Stand by.

Okay.

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.

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.

Sounds good.

Yes, sure does.

Apollo 13, Houston.

Go ahead, Joe.

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

Okay. Stand by.

Okay.

Okay. I'm P00 and ACCEPT, Joe.

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

Okay, Joe.

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

Okay. Going to BLOCK.

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

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

13, Houston. Okay. We got them.

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

Hello, Houston; Apollo 13.

13, Houston. Go ahead.

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.

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.

Okay.

Okay, Houston. Go ahead with the pad.

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

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

Apollo 13, Houston.

Go ahead, Jim.

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.

Yes; okay.

Thank you.

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

Apollo 13, Houston.

Go ahead, Houston.

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

Okay. Stand by.

We're in HIGH GAIN.

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

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

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

Houston, you copy 13?

Hello, Houston; Apollo 13. Over.

13, Houston. Go ahead.

Hey, were you copying my P23 results?

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

Okay.

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

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

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