Spacelog Apollo 13

And, Jack, you still up?

Still here, Fred.

Okay, when I was upstairs, just a minute ago, I noticed what appeared to be some new venting from down the service module way. I noticed that out window 1, and also saw one chunk of metal—loose metal about 4 inches square that was tumbling around—silver in color, and it, looked like it had come from somewhere down in the service module.

Okay. You saw some venting out window 1 —

And I -

Go ahead.

Yes, that's where I happened to be looking. The lighting was such that it showed up out there. What reminded me of it was I'm looking out the LM window now and I sea a good part of the new star field it's created for us. There are about a thousand little sparklies out here.

Okay, so you're seeing some venting out window 1, and you saw a 4-inch-square piece of loose metal which was silver, and—Are you still seeing the venting or has it zeroed out now?

I don't know. I left upstairs, I'm down in the LM now, Jack. I guess when Jack goes up he can take a look and let me know. Okay, I'll think about switching aft here directly. I see the Moon, and the Moon looks pretty good, Jack, so I guess our PTC still doing pretty good.

Okay, and we won't have any COMM delay if the PTC stays good.

Yes, sure enough the Moon is getting smaller.

Good, and we want to ask you another question about the venting. Is this—would you suppose—some new venting or is this venting that you just hadn't—that's been going on all the time, but which you hadn't looked at recently?

I can't really say, Jack, we've been so tied up down in the LM, I guess we kind of forgot about the other half. But I've been upstairs several times and hadn't particularly noticed any flow by the windows before, so I—my first assumption was that it was some new venting. It really wasn't very heavy.

Okay. Copy. Thank you.

And Jack's going up to take a look now.

Okay. And for your information, all of our numbers are based on amperage usage of 14 amps. And we're using only 12.3, so we're a little fat on our analysis.

And we're in a —

I'll tell you, this Aquarius has really been a winner.

Well, that's one of several. And we want to tell you something that I told Jim earlier, and that concerns control. Right now you have control in hardover if you need it, but when we go to some normal control modes, since we have the quad heaters off. We want to have a 15-minute notice for attitude control request. Over.

Okay, Jack. Offhand, I can't imagine that since we got the platform powered down why we'd need to worry about the instantaneous control. But at any rate, we need 15-minutes warmup with the heaters before we can start using thrusters.

Right. And another thing we've done is to pull your ECS and EPC DISPLAY breakers and so—But we left your CAUTION and WARNING powered up. So if you get ECS-type or EPS CAUTION and WARNING you'll have to power up those meters with the DISPLAY breakers. And we are watching for you your PIPA temperatures, your ASA TEMP, your propellant temperatures except for the DPS propellant, and we're watching your quad temps for you.

Okay. That's very good, Jack. You're watching them. That's good enough.

And everybody's fine at home El Lago.

Great.

And, Fred, your CO₂ is building up. It's at 11 on our gage, and we've got a medical buildup to 15 millimeters, at which time we'll switch over to secondary. Looks like we've got plenty of lithium hydroxide, about 192 hours including the CSM cartridges. And as you know, we've got a way to use those. And as soon as we get them written in some good words, why, we'll pass; that along. You might be able to make one.

Okay. Yes, we'll sure give her a try. And I'm showing onboard about 12-1/2 millimeters of mercury.

Roger. And I have a flight plan update when you get a time to copy it sometime, I'll pass it along. There's no hurry on it.

Okay. Stand by 1. Jack's back now.

Okay. Jack just came hack and he said it's still coming out; it's only coming out on the commander's side. So he saw it out the same window I did, window 1. And it's between the minus Y and minus Z axis.

Okay. And of course —

Jack says it's definitely the service module which was—which was my impression, too.

Okay. So you're sure it's the service module, and, of course, the thing we're interested in knowing, is it something that is residual from before, or is it something new. And if you have any ideas about that, why we'd sure like to have them them.

Yes. Yes, Jack, I'll answer him your question in a minute, but make Jack's first impression here, is that it's not near the intensity that it was right after our mishap. And I'll have to agree with that. I'd say—he said it was a half and I said it was maybe down to a third. And Houston would like to know if you have any impressions as to whether it is still a residual from that or maybe something new.

I don't know why after I felt that. Yes, I felt it was some new something—new venting, too.

Okay. Switch to FORWARD OMNI.

Fred-o, if you think it's practical, we're ready to give you some—we're working on some camera settings for pictures of the venting. And, if you have a camera out and ready to go, let us know which one it is so we can get the settings for that camera. What do you think about that?

Okay. Jack's got the one with the 250-millimeter lens on it. That's the standard EL. And I have a surface camera out that I've been shooting hundreds of Earth/Moon pictures with, camera 1. And we also have the Reseau upstairs that's pretty handy. The command module DC camera. So you can about —

Okay. I copy that —

— take your choice, because —

I copy the 250 millimeter, the Reseau is available, but I didn't get what other one is.

Okay. I got my Hasselblad surface camera down in the LM here handy, too, camera 1.

And, Jack, if we're going to do any picture taking out the command module windows, I think we'd better do that pretty quick, or hold up until Jim and Jack get their rest done.

We concur with that.

Okay, Fred, we're not going to bother the skipper up there. We won't be taking any pictures out of the command module window until after rest period.

Shifting to FORWARD OMNI.

Okay. Fred, for your information, your CO₂ reading onboard is a little higher than what we're reading here on the ground, and so when it gets to 15 on your meter, switch to secondary. And we'd like to get a status about every 30 minutes—we'll give you a call on that. But just to let us know we're still thinking about you, we'd like you to go BIOMED RIGHT, please.

Okay, Going BIOMED RIGHT.

Hey, how do you read me on this COMM mode on S-band?
