Spacelog Apollo 13

Okay. Vance, are you there?

Roger. Go ahead.

Okay. The picture that Jim gave me on his view through the COAS was within the—the partial Earth, the lit portion laying in the top half of the COAS with the cusp laying right on the Y-Y line. And so the—The whole dark part of the Earth would be at the bottom part of the Earth, except a very thin crescent of the dark part to a line—line above the Y-Y line.

Okay. That is correct.

And that in essence—that in—Yes, that in essence would put our X-axis pointing toward the Sun.

That's correct. The plus X-axis pointing toward the Sun and perpendicular to the terminator of the Earth.

Okay.

Two other points, Fred. One is that we don't expect hardly any misalinement of your engine for the burn, so we don't really expect any rates throughout the length of the burn, especially since it's at very low thrust. Second point, request you verify that your suit temperature rheostat's in FULL COLD. That—if it—If it were in FULL COLD, that might help your cabin temperature situation. It might bring the temperature up.

Okay.

Okay. The latter was a good point. We had it in FULL HOT.

Very good.

And Roger on the—Roger on the rates, too.

Okay.

Okay, Vance. Is the T_ig time going to be approximately—Is it 105 or 105:30?

It's 105:30.

Okay. Your 104:30 time to start in is—sounds pretty good. That'll give us lots of time to get set up with the attitude business, in case we have any trouble stopping PTC and getting there and—That will give us a little time to be sitting and waiting, all set up.

Aquarius, Houston. Over.

Are you calling, Vance?

Right, Fred. We just noticed a 2-pound drop in your water quantity. Have you guys had a drink recently or do you know any reason why it might have dropped? Over.

Negative.

Thank you.

Aquarius, Houston.

All right. Go ahead, Vance.

Fred, that may be a funny in the data. The rate's gone back to normal; and we'll keep an eye on it, but we don't think you should worry about it too much.

And, Houston, Aquarius.

Go ahead, Aquarius.

Are we going to get any sort of a pad on this?

That's affirm, Fred. Estimating we'll have it to you in about 15 minutes.

Okay.

And, Houston, you might just let us know if there's any chance it's going to slip further down the road, because we're going to kind of hold to that 104:30 start time. And if you're going to delay any, we'll delay accordingly.

Roger. We won't have any trouble making that, Fred, I'm told.

Hello, Houston; Aquarius.

Go ahead, Aquarius.

Roger. We have about 104 degrees now. How does that …?

Okay. FIDO's hustling here. We'll try to get it right up to you. Stand by.

…

Aquarius, Houston. Over.

We have …

Aquarius, Houston. Over.

Vance, we have the quad heaters on, now.

Roger. Copy, Jim. And the—Jack's going to read you the pad right now, so I recommend you go ahead and get started. You shouldn't be delayed by the pad at all.

Aquarius, Houston. I've got your burn pad.

Roger, Houston. Stand by. Are you ready—Stand by to copy. Okay. Ready to copy.

Okay. A P30 maneuver pad on the DPS: purpose is midcourse 5, NOUN 33, 105:30:00.00, NOUN 81 is N/A, H_A is N/A, perigee, plus 0019.8, 0.007.8, 0.15, the rest is N/A. Shut down the engine at 1 second prior to the end of burn time. Shut down at 14 seconds manually. Ullage is four jets for 10 seconds, 10-percent throttle. Go ahead.

Okay, Jack. We've got a DPS midcourse 5: NOUN 33, 105:30:00.00; NOUN 81, N/A; H_A N/A; plus 0019.8, 0007.8, burn time 0.15, the rest of the pad, N/A. Shut down manually at 14 seconds, ullage four jets for 10 seconds, and the entire burn is at 10-percent throttle.

Okay, Fred. I want to verify that your DELTA-V_R is 0007.8.

Good readback.

And you should have high bit rate now, Jack.

Houston, Aquarius.

Go ahead, Aquarius.

Did you have readouts on our quad temps to know when we can start? We're taking a time hack. We'd just like a verification with you.

Okay, Houston; Aquarius. We're going to stop PTC at this time.

How about if you do —

Say again, Jack.

Negits on my last, Fred.

Okay, Jack. How do you read now?

Go ahead, Aquarius.

Okay. I thought you called, Jack. We're maneuvering around here to fish for the Earth.

And, Houston, Aquarius. How's the ASA package temp look now?

Okay, Fred. The ASA package temp is looking good. It's around 98 degrees, and we'd like to see it go up about 15 to 20 degrees.

Okay. Why don't you give me the word before I proceed with the AGS. We really don't need it right this instant.

Aquarius, Houston. The ASA package temp is up now so you can activate the AGS.

Okay, Jack. So we can make sure and get our timer set here, I wondered when your—you've got about 48 minutes to the burn which should be coming up pretty quick—you'd give us a hack so we could set our event timer at 12.

Roger, Fred. I understand you want a mark at 17 minutes prior to the burn. Is that affirm?

Roger. We think we got it set now. We just wanted to check it. If we don't, then I'll set it to 13, and you can give me another hack at 47 to go.

Okay. We got 33 to go.

MARK.

My mistake. It was 33 —

Right on.

Roger. It was reading 33 on my mark. Right?

Okay. You got about 105:03 GET now down there?

That's affirmative, Fred. Going through 105:03:45.

MARK.

Okay.

Okay, Jack. Give me the next number you want me to set then, and I'll take another hack here.

Roger. You're counting up, right?

Roger.

Okay, Fred. On my mark, be 35 minutes to the burn.

Standing by.

We missed her, Fred. Let's get it on the next minute.

Okay.
