Spacelog Apollo 13

Well, it's time for a little grits again here, Vance.

Apollo 13, Houston.

Go ahead, Houston.

Roger. Just expect that same CAUTION AND WARNING to come on again. And you want us to keep warning you of that thing?

Go ahead, Houston.

Roger, Jim. Just expect a CAUTION AND WARNING to come on the same as it did about an hour ago.

Go ahead, Houston. We've lost …

Roger. How are you reading me now, Jim?

Houston, Apollo 13.

13, Houston. How do you read now?

Okay. Read you good now. Seems like we've had a little trouble with the COMM today.

Yes. I guess it's partly because you are further out. We just wanted to tell you that you were going to get that CAUTION WARNING that you just got.

Right. We just got.

And I won't bother you with those calls anymore, unless you especially want them.

That's okay, Vance. You don't have to call us about that, unless it's something serious.

Okay.

We just ate a can of ham salad and that was an experience.

Roger. Copy.

It's really kind of like eating on the sly. Chasing it around.

Right. Copy.

…

Houston, Apollo 13.

13, Houston. Go ahead.

Right, we're not doing anything right now, Vance, we're just getting curious, we could start the LM entry procedures, and get everything squared away, and then when the TV comes up at 55 hours, we can just use it for the TV, and we wouldn't be worrying about checking out the SHe tank pressures and everything like that.

Okay, let us mull that one a minute here, and I'll get right back with you.

Also, Houston, Apollo 13. We'd like to move up the waste water dump and maybe the O₂ fuel cell purge a little bit early, if we could.

Apollo 13, Houston.

Go ahead, Houston.

Jim, you're clear to go on into the LM, and just advise though that the TV time is still fixed at 55 hours, and—so we'll be standing by to support your entry and we'll get back with you on a minute—in a minute on the O₂ fuel cell purge and the waste water dump.

Okay. Sounds good.

And also request your LM/CM DELTA-P which was on the flight plan for 53 hours. What did you vent it down to? Over.

We have 1.7 now. We vented it down to that figure.

Okay, you vented down to 1.7, and what did it start at?

It was about 1.1, Vance.

Houston, 13.

Go ahead, 13.

What do you read for suit pressure down there?

We're reading 4.3, Fred.

Houston, 13.

Go ahead, Apollo 13.

We'd like another confirmation, when we closed the tunnel vent valve back to LM/CM DELTA-P, we were reading about 1.7—1.75, and it slowly went up now to about—oh, I'd say a little less than 2.2. Seems to be holding there—Is there a lag in the gaging system?

Okay. We'll—we'll ask that question. Stand by.

Apollo 13, Houston.

Go ahead, Houston.

Okay, to answer your question, Jim, that increase in pressure is normal, because it was just tracking an increase in cabin pressure.

Okay. Okay.

We're not thinking today.

And, 13, from Houston, it's okay with us if you want to move the O₂ fuel cell purge and the water dump up to this time. Over.

Okay. We'll work it in shortly. Thank you.

Right.

Apollo 13, Houston.

Go ahead.

Jim, recommend you stay in the PTC until we stop it for the TV at 55 hours, in case you were thinking of —

Go ahead, Houston.

Roger. Recommend you continue PTC until 55 hours. Over.

You were calling, Houston?

That's affirmed, Jim. How do you read now?

Okay. We read you loud and clear.

Okay. The only comment that we just made was that, in case you were thinking of stopping PTC, there's no need to stop it until 55 GET when TV starts.

Right. We'll stop it when we're setting up our TV.

Okay, Houston, the waste water dump and O₂ fuel cell purge are complete.

Okay, Houston, the LM/CM DELTA-P is constant. We're going to go ahead with hatch removal.

Houston. Roger.

Is that you, Jack?

Okay, Houston; 13.

Houston, go ahead.

Go ahead, 13.

Houston, Apollo 13.

This is Houston. Go ahead, 13.

Okay, Houston; Apollo 13.

Roger. Go ahead, 13.

Okay. The LMP has entered the LM.

Roger.

Is that Big John?

It sure is. How're you doing?

Fine.

Yes, you're doing great, man.

Thank you. I had a good CDR.

You're doing it on your own now.

Yes, it feels like I'm back at home, again, John, down in here.

I hope you did a good job, John.

Roger.

Okay, Houston, we want to take the FM and bring up TV here for our own use. Then we'll go to TRANSMIT 1—at 55 hours.

Okay, Houston, we've transferred to LM power; the time was 54 hours 46 minutes 15 seconds.

Roger, Jack. Transfer to LM power. Thank you.

And the docking-tunnel index, Jack, was minus 2 degrees.

Say again, Fred, you're coming in with a lot of background noise.

Okay. The docking-tunnel index mark was minus 2 degrees.
