Spacelog Apollo 13

And if—if you can now go into your eat period or do something else while the rates are stabilizing, why, we recommend you relax somewhere and get some chow.

Aquarius, Houston. Over.

Go ahead.

Okay, Jim. Looks like your rates are damped sufficient. Recommend that you go ahead with the VERB 25, NOUN 07, ENTER bit on down through the VERB 34, ENTER, and then wish you'd stand by for us to look at it again before you go beyond that. Over.

Okay, Houston. I'll go through VERB 25, NOUN 07, down through VERB 34 ENTER, and I'll stand by.

Right-o.

Okay, Houston. That's complete.

Roger. Houston copies, and we'll —

You … monitor our rates?

Roger.

We —

You want to monitor the rates; we're 16 20.

Roger. That's the way it should be done, and we're standing by for the rates to dump out some more.

Okay.

How you coming?

Oh, we're taking stock of how much we got there, maybe sort of think about rationing some of it. I mean just to make sure we've got enough to last us and that we get enough water out. I'd hate to run out of water on the last day. Take a look and see how much we got, and fill them up and just hold them there. Yes, and I'll tell you the stuff that's good to eat now will be the candies, the sandwich spreads. Maybe the freeze—the dehydrated stuff. If you have to rehydrate it, it'd be kind of difficult. No, wet packs are good.

As a matter of fact, we might use those little—Well, how about the PLSSs?

Yes, I know, but I mean the PLSSs are bombs, too.

…

We're damping rates.

…

You guys moving around?

Okay.

Apollo 13, Houston. Over.

Go ahead, Vance.

Jim, just a reminder. Any waste water dumped at this point would really jiggle up the PTC preparation, so request you save that until we're spun up. Over.

Right. I don't think we're doing any.

No. No, I don't think so, but I just wanted to make sure you were aware of it—I thought you were.

… for a minute?

With the new space. … we're … We've just about slowed down. You're damping right.

There she is.

And, Houston, Aquarius.

Houston. Go ahead.

Okay, Vance. A couple of items we uncovered for that cartridge MOD. One is the special dust covering bag that we were going to use on the tote bags, that is pretty thick and nonporous; and we went up to the upstairs kitchen and drained water a couple of more times, and made up a whole bunch of drink bags, again; and from the pantry, we retrieved a fairly large—enclosed—enclosure made of plastic that those drink bags are in that I think we can scissor and also make do for a cover, taping it on, if that's appropriate.

Okay. Jack Lousma here has a refined version of the procedure on how to make these the easy way, and I think before too long he ought to be reading that up to you. If —

Okay.

It's not time critical to get this up to you. It's just that, before you get too far in assembling these on your own, we'd kind of like to give you the benefit of experience down here.

Okay. Who—Who built them back there.

Tony did some of it, and Jack's been working on it, too. So we've had a big effort on it.

Great.

We would encourage you to wait until tomorrow to receive that procedure, but we can send it up sooner, if you insist. Over.

No, that's all right, Vance. Before we have to worry about that I guess we got another primary and three secondaries to go through.

That's right.

You know, sometimes those cartridges have—I guess they rejuvenate.

Aquarius, Houston. Over.

Man, that's a wicked low pressure down there. I wish I was on it. (Laughter).

We're with you.

Roger. In the LM, you have 215, that is 2 1 5, pounds of water, usable. That would average out over 61 hours to 3.5 pounds per hour available. Okay.

Okay. And after you power down, we expect that you will be using water at the rate of 3.2 to 2.7 pounds—That's at 14 amps per hour electrical usage rate. One note, this does not—When we speak here of water available, this does not include CSM water and PLSS water, so that's add on. Okay, next, LiOH. Using the CSM cans, you will have 16 cans at 12 hours per can to give you 1 9 2, or 192 hours, of LiOH. And, in the LM, using its cans, you have 44 hours remaining.

Vance, is that with the PLSS secondaries?

That's affirm. That's affirm. That includes PLSS secondaries.

Okay; oxygen. You have remaining 44 pounds in the LM. At a usage rate of 0.36 pounds per hour, that leaves you 120, or 1 2 0, hours of oxygen. Okay. Next, RCS. RCS A stands at 6 2 percent and B at 6 2 percent. We only expect 2 percent to be used for the PTC, so you're in good shape for RCS. Next, DPS DELTA-V. You have 1190 feet per second remaining. And, finally, CSM EPS. We estimate that you have 99 amp-hours. That's an estimate. And that's it. Over.

Okay. I copy.

Okay. And just a question. It would be interesting to hear from Jack to see if he thinks that main B bus is good. If he has any idea of how, if whether it's good or not, this would influence our steps in the future; for example, we might want to try to test main B to see if it is, in fact, good so that we'd know how to set switches for entry.

Roger. Just a minute. They want to know whether you think main bus B is any good for the command module.

Vance, while Jack's got on the loop, let me pose the question of how we're planning on doing this midcourse, if we are going to power down the PGNS.

Would you stand by on that, Jim? We'd like to give you a procedure for that later on.

Okay. Got a midcourse at 104 hours, he's going to give us a procedure for that later on.

In short, Jim, we don't expect any problem, but we'll explain further later on.

Okay.

Deke says get a night's sleep. He says you've been working hard, and you ought to relax a little bit and be ready for tomorrow.

Vance, this is Jack.

Go ahead, Jack.

Okay. Let me give you my observations on main bus B. Things happened pretty fast there, and we first heard the impact or explosion or whatever caused it, I'm not sure. The next—About 1 second later, there was a MASTER ALARM which was the MAIN BUS B UNDERVOLT. I looked at the voltage, and the voltage was good at this time so I'm suspecting it was a spike. Fuel cell 3 was also good, with good flow. However, Fred, at that point, was coming into the command module and got over into his seat. At that time, we shortly had an AC BUS 2 light about the time he got into his seat. He looked at the MAIN BUS B and the MAIN BUS B was reading ZERO. It, however,—and the fuel cell flows were ZERO. I'm kind of suspecting that perhaps we do have a MAIN—a current MAIN BUS B. But that's merely a guess. I never did try to reset it. We were having other problems with the MAIN BUS A, having an UNDERVOLT and a few other things like that. I'd kind of like to hear what your feelings are down there.

Well, Jack, we copy your information. And we'd like to hold off because we're still working the problem. So we'll have to give you information later.

Thank you.

Aquarius, request AFT OMNI.

Vance, are you back with me?

Roger. We're with you.

Okay. We lost lock there. We switched OMNIs. Just for my own—kind of to get my thoughts in order, I'd kind of hear what—I'd like to hear what kind of entry you're planning. EMS or PGNS or what ?

Okay. PGNS entry is being planned, and people are at work on checklist changes and that sort of thing.

Okay. Real fine.

And—we'll—We'll give you the CSM stuff tomorrow, but basically we expect that main bus B is good and we're going to work up a procedure to test it.

Okay. Those are my thoughts, too.

But —

You think main bus B is good, don't you?

That's affirm.. We think it is, but we want to check it out anyway. We think you guys are in great shape all the way around. Why don't you quit worrying, and go to sleep.

Oh, that—That's our boss, Deke.

Well, I think we just might do that—or part of us will.

I mixed up. How many more of those—Are we hot mike? —

Yes.

Yes, I'm mixed up. You had 15? I mixed up seven more. So we got 22. By the way, there's still some water that's- it's not enough pressure to mix up another drink, but there is some water out of there, if you want to get some water out of the drink cup.

That's good; I could use some.

We ought to use that oxygen up and not waste it. (Cough)

You monitoring right now?
