Spacelog Apollo 13

No. We don't want you to do that. Read me your FDAI angles, and let's compare them with what we have down here.

Okay. You're looking at them in the DSKY. I've got roll of 8.47; pitch of about 0.51; and yaw looking at about 3.750.

Okay, Jim. Those are very close—I guess all you need to do is trim them up a bit.

I plan to do a final trim—AUTO trim, and then a four-jet translation.

Okay, Jim. For fuel conservation, we'd prefer you to trim it up MIN IMPULSE, and there's really very little trim required; and then go ahead and do it AGS. We're on the expected fuel usage, but we're just being old ladies about it.

Okay. Understand. My only question, Joe, is the fact that both the roll and the yaw needles did not go to null when I did an AUTO maneuver. I'd tried to go manually to the attitude; and then went to AUTO, but the roll and the yaw do not come in at all.

Roger. I haven't got an answer on that yet, but your attitude looks very close.

Okay. I can take it on …

And, Houston, Aquarius. I'm not sure that if I follow and null the needles, that will be the proper attitude.

Okay. Stand by 1, Jim. We're talking about it. It's going to be very close; in any event, close enough.

Okay.

And, Jim, just for your information, I have the entry pad. I have the landing area weather summary, which you probably don't even have to copy, but which I'll read up to you when you're ready; and some stars for Jack that I'm holding for him for later on.

Okay.

And, Joe, Jack says all the injector temperatures, he just checked them again, and they're all over 3.9 —

That they're all over 3.9 now. Thanks a lot.

You can tell him that it's looking good to us. They were even happy with the previous ones.

Okay.

And, my only question, Houston, is do you want me to null the PGNS needle manually?

Okay. Stand by 1 more minute, Jim.

Houston, Aquarius.

Go ahead, Aquarius.

Yes. I guess the basic question is comparing the balls here and out the window it doesn't look too unreasonable, and I guess Jim says the COAS is yawed and roll slightly off from what he might eyeball; but yet, the FDAI air needles for PGNS are showing a full scale left in roll and full scale left in yaw. …

Okay. Go ahead.

Yes. It appears if we track those we, obviously, aren't going to be on the attitude that we burned the last midcourse.

Okay. Well, this attitude we passed you is not quite alined to the terminator, and stand by on this.

How you doing there, Houston?

Oh, we're getting there, Jim. We're—we're all agreed that you're almost, but not quite, in the proper attitude, and we're just trying to get you one firm recommendation on how to proceed from here.

Okay. I have nulled the null—roll needle and the pitch needle now and I'm yawed—rolled left now. I'm rolled left about 9 degrees.

Okay. Understand the needles are nulled.

He's getting along, all set to go. And I'm going to go into PGNS ATT HOLD.

Roger.

Aquarius, Houston.

Go ahead.

Roger. Again for fuel-consumption reasons, we'd like you to go back to the AGS mode you were in rather than PGNS ATT HOLD. Over.

Okay. I'm in PGNS MINIMUM IMPULSE right now while we're firing. And I'll go back to the AGS mode.

Okay, Jim. PGNS MIN IMPULSE is okay; AGS is okay too. It's your choice.

Soon as we get rid of the service module, Joe, I think I'll be able to maneuver a lot better.

Sure thing.

Okay, Jack just reported that all thrusters fired on both rings.

Real fine. Real fine.

And SM JETT at 138:12.

Roger. Understand; that's SM JETT, 138:12. It's not that time critical, Jim.

Can we do it at any time, Joe?

I think so, but let me check. Aquarius, Houston. That's affirmative. You can jettison the service module when you are ready; no big rush, but any time.

Okay. Sounds good.

Aquarius, Houston.

Go ahead.

Roger. We recommend that you use the AGS for the separation maneuver, because we'd like to get the proper weight in for the DAP before we use the PGNS again.

Roger. We will. Stand by.

Copy that.

Yes, it looks like it got to the SPS bell, too, Houston.

Think it zinged the SPS engine bell, huh?

That's the way it looks; unless that's just a dark brown streak. It's really a mess.

Okay, Jim. We'd like you to get some pictures, but we want you to conserve RCS. Don't make unnecessary maneuvers.

And, Jim; Houston. In particular, of course, we don't want any translation maneuvers.

Right on that. Joe, you realize that when I went up to the SM SEP attitude, I had to use TTCA to do it.

That's affirm. We know that. That's okay.

All right. She's drifting right down in front of our windows now, Houston.

Okay.

Okay, Joe, I'm now looking down the SPS bell, and it looks—looks okay on the inside; maybe it is just a streak.

Okay. Copy that, Fred. Was the bell deformed on the outside or just nicked or what?

I think the explosion, from what I could see, Joe, had—had stained it. I don't know whether it did any actual deformation or not.

Okay.

Man, that's unbelievable!

And, Joe, looks like a lot of—a lot of debris is just hanging out the side near the S-band antenna.
