Spacelog Apollo 13

Standing by for the 88-hour time hack.

Okay. We got a minute to go.

Okay. Coming up on the 88-hour mark. I'll give you a 2-second delay. Stand by to mark.

MARK.

How are you doing, Jim?

Pretty good, Jack. Say, you might have the people look at our DPS burn card to see what changes have to be made on it for the burn.

Heard you say look at the DPS burn; you'll have to say what about it again, please.

Roger, Jack. You might take a look at our DPS burn card, our checklist card that we have in the LM, and see what changes might have to be put in that checklist.

How're you doing there, Jim?

Okay, Jack. It appears that we're going—funny diversion here, the PTC attitude in—in pitch. I'm going to do a LPD check now, but the last time the Moon went around, it was above—way away above the LPD angle and I see the Earth coming around now which is going to be pretty low. They oscillate back and forth, but each time they seem to get a little farther away from the center line. You might think of some procedure to reestablish PTC, if it's necessary.

Okay.

Jim, the only way we know of getting the as good or a better PTC than you've got right now is to crank up the G & N and we—We don't want to do that. So our plan is to just take whatever we get out of this, and later on, it may turn out by the time you get to burn attitude, you'll be right where you want to be.

Houston, Aquarius.

Go ahead.

What's our course of action to set up PTC after this midcourse at 107?

We thought you'd ask that.

The only thing we can try to do, Jim, is to get the thing up manually and see what happens. There must be a better answer than that —

Okay.

— and one course of action is to omit the midcourse and make a total midcourse, say, about 8 hours before entry. We haven't decided yet.

Right now we're talking about a 7-foot-per-second midcourse at 104 hours. And extrapolate that down to about 8 hours before entry. We gave you a pad for that—that's about, only 19 feet per second, so if it doesn't change too much—and we can get all kinds of DPS.

Houston, Aquarius.

Go ahead, Aquarius.

Can you think of any normal venting phenomena that might occur like maybe—a hydrogen tank that's over-pressurized relieving in the window?

Yes, we thought of that, Jim.

That is one possibility that we've though of, Jim, because—We heated up that tank, and we haven't been using any hydrogen and, therefore, it could be venting in the overboard release.

Right. The only other thing I can think of when I look at it through the AOT is—it did appear to be coming from one spot; but that's the only difference although I can't see where it is coming from because it's beyond the curvature of the command module. But, it appears like it might be coming from more than this one spot.

Okay. Thank you. We hope that when we crank up the command module tomorrow that we'll be able to—or later on today—that we will be able to identify more closely what it's been coming from. But, the guidance guys say that they haven't been able to see the results of any venting in their data and it would take a very, very small amount to perturb their data.

Well, that's a note of encouragement.

(Music)

You got a Chinese band going up there?

Oh, sorry. I forgot all about hot mike.

Jim, we've had you scheduled for an eat period about an hour ago. I suppose you've taken care of that. The other thing is we're kind of interested in knowing how long you're going to be at stick there, or if you're going to go back to bed or what?

Okay, Jack. We're—We're going to set up a regular watch and sleep period here. Fred was up for a long time, so I got up a little bit early to relieve him. Jack and Fred are now asleep, so I'm going to let them sleep as long as they can, and then we'll have an eat period and then I'll go back to bed for a bit. And we'll separate the schedule.

Okay. We're right at the point now where, according to the flight plan that we had made up for you, that you would have all finished eating and you and Jack would have the duty while Fred went to sleep. So, essentially, according to the plan we've got, you got up about 3 or 4 hours early. And—The next time that we have that as a rest period for you is at 96 hours, which is 7 hours from now, and an hour before that, say at 95 hours, all three of you would eat, and then you and Jack would hit the sack again and Fred would have the duty until 102 hours. We'd be glad to take care of this work-rest cycle for you.

Okay. That's good. Let me—Let me wait until they get up, or at least Jack gets up. He should be getting up before Fred. And we'll try to get back on the schedule. I hate to wake everybody up right now though, if they're sleeping.

Okay. Your choice on that. As soon as Jack gets up, I'd suggest we go ahead and break up these lithium hydroxide canisters and make a couple of them. Jack could work on that. It's going to take four sets of hands, I think.

Aquarius, Houston. Over.

Go ahead, Houston.

Hi, Jim. We've got a flight handover in about 2 minutes, and we'll have a temporary loss of COMM. You don't need to switch antennas. Over.

Aquarius, Houston through Madrid for a COMM check. How do you read?

Loud and clear, Joe. How me?

Okay, now -

Okay. Now we've got to make the belt real taut here.

How's that?

Okay, Joe.

Okay, Jack. Did you have —

— Hey, Houston, are you reading?

Jack —

— We've got the two belts around the top and the one around the bottom all done.

Okay, fine. The next step now is to anchor that tape, and the way we want you to do that is to cut about a 2-foot length off the roll and then tear it lengthwise so that you have two strips about 2 feet long and about a half an inch wide. And you'll wrap those around the canister at right angles, more or less, to the tape that you've got so that it goes across the top and across the bottom; and when it goes across the top and the bottom, put it so that it's outboard of the center hole and try to get it over one of the ridges between the screens, so that it won't block the flow. Is that clear? Over.

Yes, Joe. Very good.

Okay. Press on.

Okay. I've got a cut length right here and we'll tear it lengthwise … and I'm going to go around right here at this ridge all the way around at right angles and anchor it …

Yes.

Joe, just to clarify that, sticky end down. Right? On the tape that I am putting on now?

I didn't quite copy that, Jack. Say again.

Okay. That will be the sticky end down on the container, right?

Oh, that's correct. I forgot to say that. That's right.

… hold that one right here, if I can set it.

Okay, Joe; Aquarius. We've got that done.

Okay, Jack. The next step is to get the EVA cue card and use it to form an arch over the top of the canister; just tuck one short end under one ridge on the top the other one against the ridge on the other side so that it forms a rounded arch over the top of the canister. You see, Jack, what we're going to do is slip the bag over this whole assembly and the cue card will serve to keep the bag from being sucked down against the screen. Over.

Okay. I got the idea.

Okay. And when you've done that, to hold the arch in place, just run a strip of tape across the side of the—that is, across the top of the arch, and anchor it down to the sticky strips along each side.

Okay. I got the idea. Okay. Let me just repeat it here. Take a cue card, form an arch over the top, bringing it under the side here. When we're through, run a piece of tape from the sides across the top of that to anchor to the other side.

That's correct.

Okay. It worked.

The top. … Across the top.

Looks like you're going to have to cut the cue card slightly.

Doesn't have to be really … over that the only thing we're … we can just take the scissors and cut off the edge here. The only thing this does, Jim, is prevent this from being sucked down into the container.

Okay, Joe. We've got that arch built, and it's all taped in securely.

Okay, Jack. The next step is to stop up the bypass hole, which is the hole in the center of the bottom of the canister; we want to stop that up because we don't want to bypass the flow; and I forgot to tell you to get something to stick in that hole. We recommend that you either use a wetwipe, or cut off a piece of sock and stuff it in there, or you could probably even crumble up some tape and use that. Over.

Okay. We'll start plugging up the bypass hole.

Okay.

Plug that hole. We can either—we can put some either—Let's cut a piece of your towel there.

Okay, Houston; Aquarius. We have the bypass hole all plugged up.

Okay, Aquarius. The next step is take the inner LCG bag that you cut open, and slip it over the top of the canister, when you do that, orient it so that the ears of the bag, that is, the corners should stick out on the closed end—are oriented along the open ends of the arch, because we're going to snip one of those corners to stick the hose in. Pull it down until it fits snugly over the arch. Over.

Okay, Joe. Slip the bag over the canister so that the arch is at the bottom of the bag and that the ears are along oriented along, let's see—I guess it would be—would be at the sides of the arch.

Depends on what you mean by sides—over the—the open ends of the arch.

Right, the open ends of the arch.

Okay.

Okay, Joe. We've got that done.

Okay. Now press the bag against the sticky belts that we put on the sides of the canister. If there is any excess material, just kind of pleat it, so that it makes a fairly tight seal, and then take another 3-foot strip of sticky tape and wrap it around the outside of the bag opposite the bottom—the bottom sticky belt—to make a nice tight seal.

Okay, Joe. We've got the canister inside the bag, two strips around the sides of the bag, real tight, and both sealed.

Okay; real fine. Now there's probably a couple of inches of excess bag sticking our around the bottom of the canister. To prevent this from sucking in against the bottom screen, we'd like you to trim it off with the scissors, and when you've done that, we'd like you to cut two more strips of tape about 12 inches long or so, cut the—tear them lengthwise to get four pieces 12 inches long and 1/2-inch wide, and then use those four strips to secure the bag by passing the strips from the sides of the canister outside the bag around the bottom of the canister and back up the other side, and when you do this, just as you did on the top, make them go outboard of the hole and in between the screens. Over.

Okay. You want me to trim the excess material that's sticking off here; trim it at the edge of that canister? Or do you want any excess left over?
