Spacelog Apollo 13

Okay. I'm on the other OMNI now. I just said that you're coming in even louder than previously.

And, for your information, Jack, I'm just going to tear into some beef and gravy and other assorted goodies.

I presume that you're doing this with the full permission and—of the commander.

And this—at this moment, who do you think is the commander?

If I was him, I'd make you sign out everything you ate, so I'd know.

Well, I'm sneaking inside of the LM where he doesn't have … Incidentally, this PTC must have some—must have a wobble mode around our X-axis there because now the Moon and Earth are back in the right perspective.

Good. Let's see if it goes the other way.

These guys down here are saying they knew it all the time.

Well, that's right. They do good work. Whoever heard of doing a P52 in the LM?

Say, Fred, sometime when you're not too busy chewing on that beef, how about telling us what the CO₂ reads?

Okay, I'm reading 13, 1 3.

Yes. It appears the wobble is going the other way, Jack, because the Earth is now rising and the Moon is starting to get lower in the window.

Roger. Could you give us an LPD number periodically?

LPD number? Yes, okay.

In fact, if you could give it two or three REVs in a row, why then we could predict where it's going and maybe help us set it up again if we have to.

Okay.

Okay. The center of the Earth has just gone by at an LPD number of 4.

And the center of the Moon is about LPD 21.

Okay. LPD 21. Is that the center of the Moon, you say?

That's affirm.

And, Fred, we're doing a little better on our water than we had anticipated. Our numbers were designed for 3.5 pounds per hour; we're using about 3.0, and expect to go a little bit less.

Beautiful.

When this flight's all over, we'll really be able to figure out what a LM can do.

Maybe it'll make the …

Okay. The Earth went—just went by about—clear above the LPD index. It was—it was, if it were extended, the number would be minus 6.

Okay. Way up there at minus 6.

Yes, there's actually no such number. I just extended the line beyond zero which, for a negative rate, is what it would be if there was one.

Right. If minus 6 was there, that's where it would be. Right?

That's right.

Do you still have that super-dense star field?

It's still there. I'm looking at it right now. I can look at—the Sun is right behind me, then all these sparklies show up. Yes. It kind of looks like I'm right in the middle of the—of the Milky Way. There are several thousand little sparklies at various ranges out as far as I can see …

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.
