Spacelog Apollo 13

What's that?

We DOWN VOICE BACKUP?

Yes.

Houston, Aquarius.

Go ahead, Aquarius.

Roger. We still want an activation start time for a burn.

Understand. You want a powerup time, is that affirm?

That's affirm.

Okay. Stand by.

Okay. Look it. Let's get the cameras squared away; let's get all set to burn. We got one chance now.

Okay.

We're not going to hack it at 152 hours.

Aquarius, Houston. Over.

Go ahead, Houston.

Jim, regarding the start time for the powerup, you mentioned an hour and 15 minutes. We think that is adequate. This is crew preference depending on how much time you think you need. We would go along with an hour and 15 minutes —

Okay—Okay, sounds good.

Okay, Fred-o. You been through most of that checklist for an hour? Let's get it out and …

78 hours and …

Okay. Let's …

Hey, Jack. Did you … camera back up …?

Okay. Page 1.

Okay,

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. We have about three items for you. We have a maneuver pad, P30 LM maneuver, again; and the maneuver pad for the CM for splashdown. We also have a checklist change with contingencies,—LM contingencies checklist. And, I'll stand by while you're gathering the books.

Okay. I'm at—I got the contingency book, so give me that one first.

Okay. Page 18 …

Okay. I'm at page 18.

Okay. About half-way down. When propellant quantity equals 30 percent, or rather 37 percent, we would like to change that line to read—when time to go is equal to 10 seconds—Of course, the line under that remains the same then, DESCENT HE REG 1 to CLOSE.

Okay. When time to go equals 10 seconds, DESCENT HELIUM REG 1, CLOSE.

That's affirm. Before I start on the pads, another comment. The general indications that we gave you before about the Sun being in the commander's window and about stars in the AOT, such as that might be used as general indication for your attitude for the burn, that's all out the window. We are just going on the Sun check that we made earlier and we don't feel that we have information that is good enough to give you the star and the Sun in the window information.

…

Okay. You're very weak now. When you are ready to take the P30 LM maneuver pad, I'll be reading it up.

Okay. Go ahead with the …

Okay. This is P30, LM maneuver pad, PC plus 2 hours, starting with NOUN 33, 079:27:38.30, plus 0833.0, minus 0050.9, minus 0213.9, N/A, plus 0020.5, 0861.5, 4:24, 272, 081, and the rest is N/A except for comments as follows. Ullage, two jets, 10 seconds; CSM weight, 62480; LM weight, 33452 and the DPS throttle profile is the same as before, 5 seconds at minimum, 21 seconds at 40 percent, and the remainder of the time at MAX. Over.

Okay, Aquarius; Houston. You're coming in about 1 by 1 now. Advise that I heard everything except the beginning NOUN 33 values and the comments. Please repeat the readback on those.

Okay. I'm going to UP with the POWER AMP here, Vance.

Houston, how do you read Aquarius now?

Hey, you're loud and clear now.

Okay. I got the POWER AMPS now, PC plus 2 hours, 079:27; 38.030, plus 08330, minus 00509, minus 02139, N/A, plus 00205, 08615, 4:24, 272, 081; rest N/A.

Roger. Forty percent for 21 seconds, I believe is what you read back. And all the rest is correct. Now, for the maneuver pad for the CSM. Over.

Okay. Stand by.

Okay. Go ahead.

Okay, Fred-o. This is maneuver pad monitor PC plus 2 hours; all N/A until you get to NOUN 61, latitude minus 21.65, minus 165.00, 1163.5, 36292, 142:39:22. Over.
