Jack Swigert (CMP)

… But we're in this wobble.

Fred Haise (LMP)

… pass … then it'll come back down.

Fred Haise (LMP)

Hey, Aquarius; Houston. How do you read me?

Joe Kerwin (CAPCOM)

Aquarius, Houston. Okay. Go ahead.

Fred Haise (LMP)

Okay, Joe. It—Our wobble in this PTC has picked up where the Moon is running by pretty high in the window and the Earth pretty low; so I expect—On the side where the Moon's present, we're having a little bit of trouble with the COMM … breakout there in a couple of places.

Joe Kerwin (CAPCOM)

Okay. Roger that, Fred.

Fred Haise (LMP)

… pressure gage as far as the noise … get the thing from the AFT. …

Jack Swigert (CMP)

Okay, Joe. I'm all set to copy that procedure for powering up the command module from the LM, whenever you want to give it to me. When did you, I guess you want to put battery A out of the CHARGE, huh?

Joe Kerwin (CAPCOM)

Jack, we're not certain when the best time is to implement this procedure, and what we want to do at this time is read it up to you, so you'll have it and understand it and we'll—We'll be able to do it quickly when the time comes. And I don't have it for you quite yet. Over.

Jack Swigert (CMP)

(Laughter) Okay. All right. I'll be standing by to copy it whenever you get it.

Jack Swigert (CMP)

Joe, I got to switch antennas here. Okay, Joe, I read you on the FORWARD antenna.

Joe Kerwin (CAPCOM)

Okay, Jack, I have the procedure now to read up to you. Before I do, I want to mention something that will be of interest to Fred. We are looking at the SHe tank pressure rise and we expect it to blow. We don't know exactly what time it will go, somewhere around 105 hours or perhaps later than that. We've got plenty of blowdown capability. We just thought you ought to be informed.

Jack Swigert (CMP)

Okay. Stand by. I'll tell him, now.

Jack Swigert (CMP)

Fred, they said they're looking at the SHe tank pressure rise, and they expect it to blow somewhere around 105 hours … Okay. Fred thought they did. …

Joe Kerwin (CAPCOM)

Okay. Real fine. Are you ready for the procedure, now, Jack?

Jack Swigert (CMP)

Yes. Joe, how long is it? Is it a big long one, or a short one, or a medium sized … about how many pages?

Joe Kerwin (CAPCOM)

It's about—I'd say 15 to 20 steps, Jack. Some of it is LM stuff, and the rest of it is in CSM.

Jack Swigert (CMP)

Okay. I got a fresh page here, and I'm ready to copy.

Joe Kerwin (CAPCOM)

Okay. I'll give you the LM steps first. They have to be done first, and the first step is on panels 11 and 16, circuit breakers ASCENT CA, ASC ECA, two to close.

Jack Swigert (CMP)

Okay. Panels 11 and 16 CBs ASCENT ECA to closed.

Joe Kerwin (CAPCOM)

Okay. Next step: panels 11 and 16 CB ASCENT ECA CONTROL, two, to close. Over.

Jack Swigert (CMP)

Okay. On 11 and 16 CBs ASCENT ECA CONTROLs to close.

Joe Kerwin (CAPCOM)

Okay. That's correct. The next step is BAT 5 and 6 NORMAL FEED to high; those are switches.

Jack Swigert (CMP)

Okay. BATs 5 and 6 NORMAL FEED, ON.

Joe Kerwin (CAPCOM)

That's correct. Next step: BATs 1 and 3 to OFF slash RESET. Over.

Jack Swigert (CMP)

BATs 1 and 3 to OFF slash RESET.

Joe Kerwin (CAPCOM)

That's correct. Next step: wait 30 minutes for preconditioning.

Jack Swigert (CMP)

Okay. That's wait 30 minutes for preconditioning.

Joe Kerwin (CAPCOM)

That's correct, and the last LM step for now is BATs 2 and 4 to OFF/RESET.

Jack Swigert (CMP)

Okay. BATs 2 and 4 to OFF/RESET.

Joe Kerwin (CAPCOM)

That's correct. Now we'll go to the CSM, and the first step there is connect LM/CSM umbilical. Over.

Jack Swigert (CMP)

Okay. Connect LM/CSM umbilical.

Joe Kerwin (CAPCOM)

Okay. The next step, on panel 5, CB LM POWER-1 MAIN B and LM POWER-2 MAIN B, both, closed. Over.

Jack Swigert (CMP)

Okay. On panel 5, CB LM POWER-1 MAIN B and 2 MAIN B, both, closed.

Joe Kerwin (CAPCOM)

That's correct. On panel 5, CB EPS SENSOR SIGNAL MAIN B to close. Over.

Jack Swigert (CMP)

EPS SENSOR SIGNAL MAIN B closed on panel 5.

Joe Kerwin (CAPCOM)

That's correct. Next step, panel 250: CB BAT C POWER ENTRY/POSTLANDING; closed. Over.

Jack Swigert (CMP)

Okay. On panel 250: CB BAT B POWER ENTRY/POSTLANDING, closed.

Joe Kerwin (CAPCOM)

That's Charlie. Verify MAIN BUS voltage; then, LM POWER switch on panel 2 to CSM. Over.

Jack Swigert (CMP)

Okay. That's verify the MAIN BUS voltage, and switch LM POWER to CSM.

Joe Kerwin (CAPCOM)

Okay. That's correct. Then go back to 275, CB MAIN B BAT BUS B to open. Hey, Jack, that's the step I skipped for you, I'm afraid. Before verifying MAIN BUS voltage, you have to, on panel 275, close CB MAIN B BAT BUS B. Over.

Jack Swigert (CMP)

Okay, Joe. How are you reading on the AFT OMNI.

Joe Kerwin (CAPCOM)

You're okay now. Go ahead.

Jack Swigert (CMP)

Okay. After putting the BATTERY B POWER ENTRY/POSTLANDING on, then I want to push the—on panel 275 MAIN B to BAT BUS B in, huh?

Joe Kerwin (CAPCOM)

That's right. Then you go to verify MAIN BUS voltage, LM POWER to CSM, and then, on panel 275, circuit breaker MAIN B BAT BUS B to open. Over.

Jack Swigert (CMP)

Okay. After verifying the MAIN BUS voltage connecting the LM POWER to CSM I want to pull MAIN B BAT BUS B, or MAIN B to BAT BUS B, open.

Joe Kerwin (CAPCOM)

That's correct. And then on panel 250, circuit breaker BAT B POWER ENTRY/POSTLANDING to open, and verify MAIN BUS B voltage.

Jack Swigert (CMP)

Okay. Panel 250 BAT B POWER ENTRY/POSTLANDING, open, and then verify the MAIN BUS voltage.

Joe Kerwin (CAPCOM)

Okay. That's correct. The last steps are to get the LM back on descent batteries. The first step is BATs 1, 2, 3, and 4, HI VOLTAGE, ON. Over.

Jack Swigert (CMP)

Okay. Then the next step is a LM step, BATs 1, 2, 3, and 4, HI VOLTAGE, ON.

Joe Kerwin (CAPCOM)

That's correct; and the last step in the LM, BATs 5 and 6 to OFF. Over.

Jack Swigert (CMP)

Say again; you cut out there, Joe.

Joe Kerwin (CAPCOM)

Okay, Jack. The last step in the LM, BATTERIES 5 and 6 to OFF. Over.

Jack Swigert (CMP)

Okay. BATs 5 and 6 go OFF.

Joe Kerwin (CAPCOM)

That's correct. That should configure you. Note that circuit-breaker protection on that circuit limits the available current to 15 amps. We think we can do quite a bit with it though. And the LM/CSM umbilical will be hot and MAIN BUS voltage may be monitored by selecting MAIN B on the gage. Over.

Jack Swigert (CMP)

Okay. And I'll be ready to implement this whenever you call it up.

Fred Haise (LMP)

And how do you read, Joe?

Fred Haise (LMP)

Okay. While Jack was on COMM, I was looking out the docking window here, and I could see another good shower of particles coming out of the service module. And the position this time appears to be on the other side. Before, we'd always seen them out of window 1, and where I'm looking at it from here, it looks like it'd be down below window 6 somewhere in the service module. Jack's going upstairs to see what it looks like up there.

Joe Kerwin (CAPCOM)

Okay. Good deal. We copy that, Fred. And to show you how relaxed we are about the entry, Ken is looking at—giving you guys a chance to—prior to going into entry, PREP to snap a few pictures of the service module.

Fred Haise (LMP)

Ken is, huh? (Laughter)

Joe Kerwin (CAPCOM)

Yes, he's got all that film up there, and he doesn't want to waste it.

Fred Haise (LMP)

Oh, I thought maybe you'd want me to do a PLSS EVA to go shoot pictures or something.

Fred Haise (LMP)

You're right; we got a lot of pictures.

Fred Haise (LMP)

I guess I agree it surely would be nice to document it someway if we can, but it doesn't look like …

Joe Kerwin (CAPCOM)

Yes, we think it'd be a lot of help.

Fred Haise (LMP)

Joe, how do you read me?

Joe Kerwin (CAPCOM)

Aquarius, Houston. Go ahead.

Fred Haise (LMP)

Okay. The condensate transfer worked great.

Joe Kerwin (CAPCOM)

Stand by a minute, Fred. We're in a bad COMM mode.

Fred Haise (LMP)

Okay. The waste transfer into the condensate can works real well, Joe.

Fred Haise (LMP)

So, I guess we can keep FIDO happy with no overboard dumps.

Fred Haise (LMP)

Yes, that brings up one more possibility, Joe.

Fred Haise (LMP)

Brings up another possibility. Now that we've got all of that stowed into the bags and the condensate can, we could probably blow all of that through the PLSS …, I wonder how the sublimator would work on waste water.

Joe Kerwin (CAPCOM)

It might work if we had to do it, Fred. Right now we're looking at a comfortable excess of water through the sublimator. We were talking among ourselves this morning about having you try out the PLSS to ascent tank water-transfer situation and we decided not to do it, not to recommend it, because we figure it'd take us 30 hours to empty one of the ascent tanks, which you have to do in order to get PLSS water to it, and we'd rather use the descent water and we don't think we've gotten any sweat. Over.

Fred Haise (LMP)

Okay, Joe. I don't think there's any question about it from the plumbing standpoint that we could do that if we had to.

Fred Haise (LMP)

And, how do you read, Joe?

Joe Kerwin (CAPCOM)

Read you pretty good, Fred. Go ahead.

Fred Haise (LMP)

I think our PTC wobble is growing worse. The Earth now is really up to the top of the window. I have to get way down almost to the floorboards to view it. Conversely, the Moon is way down at the bottom of the window.

Fred Haise (LMP)

Far more wobble than I noticed on my previous watch.

Joe Kerwin (CAPCOM)

Okay. Copied that, Fred. And our thermal people will be looking at it. One of the things we're talking about relative to the midcourse correction is we'd like not to do it before the SHe tank goes, if it's going to go, just so it won't give us a problem reestablishing PTC. And right now our people think that the burst disk will pop around 106 hours.

Fred Haise (LMP)

The L-shaped bag is …

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Okay, Fred. Since you went ahead and used the PLSS condensate container, we got the procedure in for using it. I'm not going to read it up to you except that it cautions a little bit about shaking it too much or about filling it too full, because they feel that if you do that the vent valve might unseat and the bag might leak a little bit. Over.

Fred Haise (LMP)

Okay. We haven't removed it from its stowage spot. We just left it right in place, and just—he mated the tank at the end of the cable and hooked right into that.

Joe Kerwin (CAPCOM)

Understand. That's satisfactory and recommended that you leave it in the stowage spot. That should help the situation.

Fred Haise (LMP)

We got a—we got another flow shower going on outside. Particles, seeing them vented against the service module. Jack thinks it may be an H2 vent. …

Joe Kerwin (CAPCOM)

Okay. Copy that. What window are you looking at it out of, Fred?

Fred Haise (LMP)

Out the LM docking window.

Joe Kerwin (CAPCOM)

The docking window. Roger that. Somebody just handed me your latest consumables status report, and you're using between 11 to 12 amps an hour real steady, and it looks real good.

Jack Swigert (CMP)

Joe, what are you showing for GET now?

Joe Kerwin (CAPCOM)

I think you wanted the GET, Jack, and the present GET is 96 hours 21 minutes. Over.

Joe Kerwin (CAPCOM)

And Jack, Houston. For your information, FIDO tells me that we are in the Earth's sphere of influence and we're starting to accelerate.

Jack Swigert (CMP)

I thought it was about time we crossed. Thank you.

Jack Swigert (CMP)

We're on our way back home.

Jack Swigert (CMP)

There's something that puzzles me, Joe. Vance mentioned yesterday that the planned entry is a CMC-guided entry, so I'm kind of curious as how are we going to get the alinement.

Joe Kerwin (CAPCOM)

Did you say how we're going to get guidance? Over.

Jack Swigert (CMP)

No. How are we going to get a platform alinement?

Joe Kerwin (CAPCOM)

Okay. We got a number of interesting ideas on that and the latest one I've heard is to power up the LM platform and aline it, and aline the CM platform to it.

Jack Swigert (CMP)

Okay. That sounds good.

Joe Kerwin (CAPCOM)

Okay. And we're working out detailed procedures on that, Jack.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Okay. We are taking our final look at the mid-course procedures and we have a question as to the present position of one of the switches. The switch is the AGS STATUS switch on panel 6. We'd just like to know where it's at.

Jack Swigert (CMP)

Okay, Joe. The AGS STATUS switch is OFF.

Unidentified crew member

Houston, Aquarius.

Vance Brand (CAPCOM)

Aquarius, Houston. Go ahead.

Unidentified crew member

Okay, Vance. I just heard a little thump, sounded like down in the descent stage, and I saw a new shower of snow flakes come up that looked like they were emitted from down that way. We've already decided though—I wonder what the SUPERCRIT pressure looked like now.

Vance Brand (CAPCOM)

Okay. Understand you saw a thump in the descent stage and a few snow flakes. We'll take a look down here, see if we see anything.

Vance Brand (CAPCOM)

Fred, we don't see anything wrong. For example, your SHe appears to be okay as far as we can see. The thing we don't have data on, is the … tank down there.

Fred Haise (LMP)

Okay. And I doubt if it would have been that anyway.

Vance Brand (CAPCOM)

Okay. While we have you on the horn —

Fred Haise (LMP)

We're still getting -

Vance Brand (CAPCOM)

Roger. Still getting it.

Vance Brand (CAPCOM)

While you're on the horn, be advised our calculations show you might be running out of potable water in the CSM pretty soon. Also, that you might start to have hydrogen tank venting in the CSM and a question. Next time Jack looks through the sextant and telescope, we'd like him to see how it looks. Do you have anything on the optics, any specks or anything?

Fred Haise (LMP)

Houston, Aquarius. How do you read?

Vance Brand (CAPCOM)

Aquarius, we read you 4 by 4. Go ahead.
