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. Ullage two jets, 10 seconds, CSM weight 62480, LM weight 33452; DPS throttle profile the same, 5 seconds idle, 40 percent at 21 seconds. Remainder at MAX.

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.

Monitor plane change plus 2; NOUN 81 minus 21.65 minus 165.00, 1163.5, 36292, 142:39:22.

Roger. That was starting with NOUN 61, and that's correct.

Yes, I'm sure —

— Go ahead.

I say I'm sure glad we didn't have a LM impact, too.

Right. Just wanted to verify—We had poor reception when I was talking to you before—I wanted to verify that you understand that the Sun check you made earlier in the AOT was good, and that's what we're riding on. Anything that we told you in the past about looking at the Sun in the front left window or looking at stars, like Nunki through the AOT, why, we want to forget.

Roger. Understand, Vance. I think Nunki would be kind of hard to see anyway with the Moon right here.

Right.

And, Vance, we plan to start powering up at 78:12. Is that a good time or do you think we ought to hold off a little longer?

Jim, we think that's very good.

Apollo 13, Houst—Aquarius, Houston.

Go ahead.

Fred, after the burn, we'll get the powerdown instructions, or checklist changes to you. At the same time, we'd like to get a consumables status to you. All I'll say right now is that we think you look in reasonably good shape.

Okay. Very good.

Okay. Houston, Aquarius.

Go ahead.

Okay. One CAUTION AND WARNING light here showing that you didn't call out—it's the PRE AMPS—I suppose because we don't have the ATCA breaker in yet.

Houston, are you planning to give us a state vector update.

That's—That's affirm, Jim. All we need is UPDATA LINK circuit breaker closed on panel 11, and P00 and ACCEPT and we can ship it up to you. P00 and DATA.

Okay, Vance. We're in DATA and P00 and the circuit breaker's in. Go ahead.

Aquarius, Houston.

Go ahead, Houston.

Jim, request verify RANGING FUNCTION switch is in RANGING. We need that, if it's not there now.

You got it, Vance.

Thank you.

Aquarius, Houston. Did you call?

We didn't call, Houston.

Okay.

Aquarius, Houston. Over.

Houston, are you calling Aquarius?

Roger, Fred. I would like to confirm that you are getting drinking water out of, potable water out of the command module and, if you can make any estimates of how much you use as time goes on, and how much you have used, we would appreciate it for our consumables analysis.

Okay.

Okay, Jack. Tried the procedure and out of that pressure, we got 10 drinks made. That's roughly 80 ounces.

Okay, Fred, we had a little static on that one, but I think you said that 80 ounces of water has been used out of the CM. Is that right?

Yes. Jack worked the procedure and filled as many of the drinks as he could, and he made up ten bags of approximately 8 ounces a bag.

Aquarius, Houston.

Go ahead, Houston.

Jim, just a bit of information, if for any reason you had to slip T_ig, our people here feel it wouldn't do much harm if you slipped it up to 30 minutes. The procedure, of course as you know, is not to PRO on the flashing 99 and we thought you might like to be aware that T_ig time isn't all that critical.

Okay, Vance; Aquarius.

Go, Fred.

Okay. I think it's finally coming through to us here, what you said just a little while ago. Were you suggesting that we move the T_ig up 30 minutes?

No, not at all. We're just giving you excess information. Just saying if you had any problem at all it could be slipped.

Oh, okay. Slipped 30 minutes. Okay. That's better.

Right.

You guys are pretty fast, though.
