Spacelog Apollo 13

Hey, for a change, I took the … LM … this morning, Joe.

Okay. Go ahead.

I got …

I'm afraid I didn't copy that, Fred, and while I was listening, EECOM told me that he'd like another battery charge … readout.

Houston, Aquarius.

Aquarius, Houston. Go.

You want us to start on this lithium right now, Joe, or is it necessary?

It's not time-critical, Fred, but if you have the people awake now, you might go ahead and do it. Incidentally, you probably know this, but the next several hours are going to be pretty quiet from our point of view. We're working on the entry procedures and should be ready to read them up to you in about 8 hours; and between now and then there's not an awful lot going to be going on, so you guys could be catching up on your sleep schedule. Over.

Okay, Joe.

And we would like another readout on the amps and volts.

Roger.

Okay. The volts, Joe, are 38.9 and the amps are 1.9.

Okay. Copy that, Fred. Thank you very much; 38.9 and 1.9. And EECOM is simply making as smooth a plot as he can to verify the amount of amps we're putting back into the battery. That's why he wants it at half-hour intervals. If that schedule begins to interfere seriously with your rest cycle or so, give us a call. Over.

Okay.

Yes. Jim's sleeping now, and Jack and I are awake and I just finished sleeping around, I guess, about another 5 or 6 hours, so I'm not particularly inclined to go back to sleep right now.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

Okay. We've got one of them ready to go, and it looks like we could do a pretty good job just using the tape strips. First combining them together and then just using a piece of paper and the bag … get a pretty good seal …

Hey; okay, Fred. We suspected that you'd gotten at least one on. We've noticed a partial pressure drop from the 1.8 to 0.8, which is real good.

Okay. You might run that by the CPCB and see if they approve our in-house …

Roger that.

Aquarius, Houston.

Aquarius, Houston.

Go ahead, Joe.

Roger. We're convening the CPCB on that change, Fred, but FLIGHT has given you an interim go-ahead. Over.

And, how do you read now?

Not too bad, Fred.

Okay. We've got both canisters completed now.

Okay. Roger that, Fred. And you're reading 0.1 again on the CO₂. Incidentally, are you guys having good luck getting water out of the command module?

We—We haven't tried that yet today.

Okay.

Yes. This is quite an apparatus hanging on to these hoses now. And that ECS design engineer … because it sure seems to work.

Roger that.

And, Aquarius, Houston. At your convenience, we'd like another volts and amps readout.

Okay.

How do you read, Joe?

Pretty good, Fred.

Okay. Volts, 39.0; amps, 1.7.

Aquarius, Houston. Go ahead. You're pretty weak.

Okay. We'll get it for you.

Good show.

Joe, did our sticky MOD on that—those CO₂ canisters work? I'm sorry—…

Jack, I think you asked if the canister MOD was working and the answer is, it sure as hell is.

Okay, Joe. I got the voltage. It's 39.0 amps and 1.75.

Houston, do you read Aquarius?

Aquarius, Houston. That's affirmative.

Okay. We had a dropout there for a few minutes. … on either antenna.

Gee whiz, Jack, I—when did it happen? Over.

Just now. I just got you back.

Okay. We had a handover, but that was about a half an hour ago, and I didn't call you on it. Let me check with INCO and see if he thinks everything's okay. Your COMM sounds just as good as it's ever been.

Yes. I'm in real good shape.

Jack, Houston. Over.

Go ahead.

Roger. We're checking into it. We think we lost lock in Madrid for a while, and we've got it back now.

Okay. Real fine …

Okay.

You might also check with FIDO whether we … perigee …

You're getting a little weak. Did you say you wanted to verify what—what your vacuum perigee is? Over.

Yes. …

Jack, Houston. Over.

Go ahead.

Okay. The good FIDO gives us a vacuum perigee at the present time of 23.6 with a flight path angle of minus 6.25 degrees. That's without a midcourse. He's kind of tossing around the idea of doing a midcourse-7 maneuver at 5 hours before entry. If we do it, it looks like it won't be more than 2 feet per second. Over.

Okay.

And, Jack, Houston. We verified that that COMM problem was a ground problem.

Okay. Thank you. That FIDO is really cooking today.

Oh, he's having a ball.

It must be because we haven't made any waste water dumps.

(Laughter)

You can tell Jay and David that I went for a whole flight and didn't use the bathroom.

Aquarius, Houston. Over.

Go ahead.

Jack, we'd like another volts and amps reading at your convenience.

Okay, Houston. It's 39.2 volts; 1.6 amps.

Okay. Thank you. We copy; 39.2 volts, and 1.6 amps.

Houston, Aquarius.

Aquarius, Houston. Go.
