Spacelog Apollo 13

Okay, the Moon at minus 14.

That—that's correct.

Okay. Your landing in—your weather in the landing area, which is about 560 miles south of Samoa, is now predicted to be about 1500, scattered, high broken. Waves are going to be 5 feet, the winds are going to be 15 knots, visibility 20 miles, showers in less than 10 percent of the area, and you will be landing at 08:00 local, roughly.

Say, Fred, did you get the dope on the Saturn IV impact—S-IVB impact?

Yes. Just as we came around the corner, Vance, they told us that it hit—I don't recall the position now, but it was a … impact … and recorded it on the … seismometer.

Yes. It impacted 74 nautical miles from the ALSEP and the passive seismic detected major seismic activity on all long period channels and this was—this activity was detected for 4 hours afterwards with decreasing amplitude. And the impact also was detected by the high-energy channels … The high-energy channel of the SIDE.

Yes. That ought to add …

Okay. The Earth LPD number that time was 32.

How do you read now, Jack?

I'm reading you, Fred. I've got a lot of background noise, though.

Jack, I can definitely tell we're moving away from the Moon, now. I got it all in the monocular at one time. We're right over the top of FPA 8 right now.

You're right over the top of what?

On a point between it and Censorinus—FPA 8 and—the point halfway between there and Censorinus.

Fred-o, would say the checkpoint over which you're right now?

Okay. And incidentally, the LPD on the Moon was zero, so it's coming back down. The point looks like we're just about straight over is around Censorinus and the point between it and FPA 8.

Okay. And, Jack, the Earth LPD angle is 24 degrees.

Roger. Earth at 24. And it looks like you're getting up to about 15 on the CO₂, so we want you to select SECONDARY and swap out the primary cartridge. Over.

Okay. I'll select SECONDARY and swap out the primary cartridge.

Okay, Fred. And when you select—When you swap out the primary cartridge, don't reselect PRIMARY. Stay on SECONDARY until we use the secondary up. Over.

And the change out is complete, Jack.

Okay. Copy the changeout complete, and we're reading 4.5 on the CO₂ here.

Okay. And the Earth LPD was 8 degrees.

Did you—Did you say 8 degrees, Fred?

Affirmative.

Well, I missed the Moon on that one, Jack. But I would guess—estimating back a little bit, the LPD angle was somewhere around 42.

Fred, I'm having a hard time reading you, but I think you're giving me a LPD angle.

Roger. That's it, Jack. The Moon is about 42.

You say the Moon is at 22?

Four two, 42.

How you doing there, Fred?

…

Okay, Fred. I can just barely hear you saying something in the background and I can't make out what it is.

Hello, Houston; Aquarius.

Hello there, Aquarius. Go ahead.

Roger. And Fred is being relieved now. He's—went back to get some rest. This is Lovell here who's got the duty.

Gee whiz. You got up kind of early, didn't you?

It's cold back there in the command module.

Well, what we were really thinking about doing was letting you sleep a little bit longer because we figure you're pretty worn out.

Well, I'll go back and forth once in a while to get a …

Is Jack up there with you?

No, Jack's still sacked out.

Okay, Jim. We're kind of watching this PTC a little bit. Fred's been giving us a few LPD angles as we swang by the center of the Earth—center of the Moon. We noticed that the COMM has been degrading just a little bit so you might have to talk up.

Roger. Understand.
