Spacelog Apollo 13

That's affirmed, Jim. We have you up to 10.6 now, and we're willing to go a little higher on that. We have another cartridge and we have a procedure for making the command module cartridges up. We'll pass that on later.

Oh, yes. I'm not worried about that. I just wanted to make sure that you —

Are they going to —

— that—We just don't want to go to sleep here and forget about the rise in CO₂.

Are they going to use … —

Roger. We're watching it for you —

Yes, they're getting it …

— We have it here. It's now 10.7 and we have a medical go to 15 millimeters.

That's a new one.

There's a new first for you.

Okay, Jim, we estimate we've got 1 more hour on the primary cartridge, and 6 or 7 hours on the secondary.

Okay. Fine. Say, it's a spare primary cartridge back there, too, isn't it? So that's good for another, how long?

Yes. Yes. That's yours though, isn't it?

And you're right, Jim. We've got another primary cartridge back there behind the ascent engine cover.

Right, yes. We know. Thank you.

Yes, yes, I just -

Okay. I guess you've done everything right on that panel. Let me check the middle one. Yes. You powered down and then you leave me. Tell me, I've got it.

Okay, Jack, we just thought it's about time you got a LM checkout.

But he's giving it to me inert. Of course, I'm giving him my command module, too, which is rather inert right now, too.

Aquarius, Houston.

Aquarius, Houston. Over.

Go ahead, Jack.

Roger. For your information, Jack —

You're loud and clear.

— all of our analysis is based on powerdown to 14 amps, but we're reading on you right now 12.3 and so we're better off than we were in our analysis.

That sounds good.

Jack, I thought you were going to get the sleep shift where there wasn't any excitement?

Well, I tried, but I didn't make it. I thought you were supposed to he sleeping now.

Well, Fred-o is getting something to eat, and Jim is starting to sack out so I'm taking the COMM here until Fred gets set.

Okay.

As I just—Yes, are you ready to take over? Well, he just—he just asked—said he thought I was supposed to be sleeping. And I told him that I was waiting for you to—Okay. You were off the NET when they explained the—But don't they—Can't we monitor our CDU's any more to tell when to switch antennas, so they've just—When they can see it switch—it will take a couple of minutes for them to get up. And they'll always make a voice check with you.

It came out here. I caught it. Okay. Now, are you getting squared, I'll give you the COMM here.

I don't know. […]

They're, they're showing right now 12.3 amps Their analysis is based on 14 so they're in better—Okay. Headset's yours

Okay, Jack. How do you read?

Hearing you loud and clear, Fred. OMNI.

Okay.

Okay, I heard the —

I see you luck out with all the good shifts.

Yes, I got all the good deals. I heard Jack brief you on the COMM mode so, you got any questions about that?

Okay.

And how is your PTC going? I heard Jack tell you that we can't see your CDU's. How's it going?

Well, let's see, we may be offsetting slightly, the Sun looks like it may be a little higher now. Here comes the Earth by and it looks about the same perspective. I'll have to wait to see the Moon on the other side, Jack. …

I can just barely, on the left corner of the Moon now, make out the foothills of Fra Mauro formation. We never did get to see it when we were in close, there.

Okay. I'm reading on my monitor here, Fred, that you're 16214 miles away from the Moon moving at about 4500 feet per second.

Okay.

From the sounds of all the work that is going on and is still going on, this flight is probably a lot bigger test for the system on the ground than up here.

Yes, you've been—you've been working it out a little bit.

Yes. I've really got a tough job right now switching OMNIs.

Well, everybody down here is 100-percent optimistic. Looks like we're on the up side of the whole thing now.

Yes, I guess we had better be in good shape, particularly ourselves, rested for that entry day. I think that is going to be a pretty busy one.

Right, and we're working on procedures for that. Ken's been doing quite a bit of work on getting ready for entry.

How's it going, Fred?

Okay. Just fine.

Okay. We're considering a midcourse correction at 104 hours—about 20 hours from now—18 hours from now, and it's only 7 feet per second. The other option is to keep PTC up, since we may not be able to get back into it again, and delay it. So, that's the type of thing we're thinking about, but—just wanted to let you know that you're pretty much right in the middle of the fairway there and our present tracking, with no midcourse, has you—with a Gamma of 7.11, as opposed to 6.51. So, you're already in the corridor. You're just a half a degree between the center and the outer limits and we're going to tweek that up.

Okay. That sounds good.

And—we don't—Well, we think there might have been a misunderstanding earlier on the potable water. Don't worry about drinking water. Drink all you want. There's plenty of it. There's 38 pounds, and the Surgeon recommends that you use some of the fruit juices as well. Over.

Okay. Yes, we went up and—and used the procedure to pressurize surge tank, and Jack and I made up a total of 22 drinks of—drinking water.

Okay.

And I assume that Jack is up there sleeping now too, right?

Yes. That's affirm. They're both up there.

I hate to say it, Jack, but I think our PTC is about to wobble off a little bit. I've noticed that the Earth is coming by somewhat lower in the window and the Moon is going by somewhat higher.

Okay. Understand. PTC, Earth is coming by lower and Moon is coming by higher.

Yes.

And, Fred, on this jerry-rigged command module lithium hydroxide canister, what we're going to do is we're going to have to make at least two up and use two at a time—one on each set of hoses. What we'll do is we'll connect one of these jerry-rigged boxes to the red fittings and air will be sucked through the lithium hydroxide and then blown out the blue fitting. And we're also going to, when we do this, remove the LM lithium hydroxide canister from the suit loop, either the primary or the secondary, and we're getting the words together to make it easy to build one of these things, and it looks like it will probably take two guys, so, I think we probably ought to plan to do that later. In addition, we have to go up and get a couple of canisters out of the command module, so it looks like maybe a smart idea would be to delay a little bit and have you build a couple of these later on. What do you think?

Yes. I agree, Jack. Jack Swigert and I went upstairs earlier and both got a canister, and we were scratching around for some material and thinking about using them, and that's actually why—when we made up all the water to drink because we needed the plastic container that they were housed in in the pantry, and we had that ready to use with some material plus some of the—the extra porous bags that were going to be used for the dump control that we may just cut up and use, too.

Did you come up with a design or —

Plus we got lots —

No. We just thought we'd see what we had in the way of material and stand by for your word. Of course, we also have lots of stiff-backed cardboard flight data.

Yes. We have decided to use a canister and, you know that the liquid-cooled garment has a bag around it that we think we can use, too, or that we know we can use. We've tried it. So what you have is the—a bag within a bag and inside that is the liquid-cooled garment. The bag that is closest to the liquid-cooled garment is the one we need, and we've got two of them. And then, of course, we've got to use some tape and, as you say, one of the backs to flight data file time line book or something like that, and, just using those materials, we can make this jerry-rigged canister. So, the bag that we're looking for is the one that is right next to the liquid-cooled garment, and, if we're very careful about where we cut it, we can make a pretty good rig.

Okay.

It looks like we'll have to use that bag over again, though, because we only got two of them, and I expect that we'll have to make more than two of these canisters up.

Roger.

Fred, in about 4 minutes, we're going to hand you over to a different communications site, and it's going to take us about a minute or so to reestablish uplink, so you can be prepared for that.

Fred-o, we've handed over now. How do you read?

Loud and clear, Jack.

Same here.

In fact, you're coming in a little louder.

Fred, you'll have to say again. Can't read you there. There's too much background noise. Maybe we need a new antenna.
