Jack Lousma (CAPCOM)

We're considering powering down the PGNS but we want to know what capability you have to do a coarse and fine aline. We read your conversation about being unable to see out the window very good. How about out the AOT?

Jack Lousma (CAPCOM)

Okay. And the other thing we thought you might try is to put the service module between you and the Sun and then to see if you can see anything out the window in that attitude.

Jack Lousma (CAPCOM)

The reason that we think that that would work is that it worked on Apollo 10. It made the constellations all recognizable when we put the the service module—in our case a LM, between us and the Sun.

Fred Haise (LMP)

You're down in the mud again, Jack. It appears that some other circuit is feeding through on there with you.

Fred Haise (LMP)

Okay. You're down in the mud again, Jack. Lots of background static.

Fred Haise (LMP)

Okay, Houston; Aquarius. How do you read?

Fred Haise (LMP)

Hello, Houston; Aquarius. How do you read?

Jack Lousma (CAPCOM)

Hello, there, Aquarius. Loud and clear. How me, now?

Jim Lovell (CDR)

Okay, we're reading you loud and clear, Jack. I hope it stays this time.

Jack Lousma (CAPCOM)

Okay. We'd like to brief you on what our plan is. We're, at this time, water critical in the LM. So we'd like to use as little as possible. To do this, we're going to plan to make a free-return maneuver of 16 feet per second at 61 hours, which is 37 minutes from now. Then we're going to power down the PGNS, and then we'll—at 79 hours, we'll go ahead and make another abort maneuver to kick what we got. But we'd like to get that PGNS powered down as soon as possible. That would be after the midcourse and—so how do you feel about making a 16-foot-per-second burn in 37 minutes?

Jim Lovell (CDR)

Well, we'll give it a try, Jack, if that's all we've got. That's a 16-foot-per-second DPS burn in 37 minutes?

Jack Lousma (CAPCOM)

Roger. We're working up a pad for it, but we'd want to know what you think about doing it at that time.

Jim Lovell (CDR)

Well, we'll do it. Could you give us a little bit more time?

Jack Lousma (CAPCOM)

Okay, Jim. We'd like to get a suggested time from you. We can figure out a free-return maneuver for any time you want to give us, so if you'll give us the time you'd like to shoot for, we'll figure out a pad.

Jim Lovell (CDR)

Okay, that sounds good. I think if we have a little bit more time; we want to do it right. Stand by 1.

Jim Lovell (CDR)

Let's shoot for an hour if we can, Jack. How's that.

Jack Lousma (CAPCOM)

Okay, Jim. How about 61 hours and 30 minutes? That's an hour and 5 from now.

Jim Lovell (CDR)

Okay. We'll do it and we want to be sure we talk back and forth now to make sure we get this burn off right.

Fred Haise (LMP)

Okay, in the interim, Jack, I looked around again and I saw that we have a radar and a landing-radar heater breaker in. Can I pull those out?

Jack Lousma (CAPCOM)

Affirmative. Pull them both out.

Jack Lousma (CAPCOM)

And now we want to ask you a question about alinements, and so forth. We wanted to know if you can see any stars out of the AOT. We also wanted to know if you could use the service module to cast a shadow on the LM windows and then look out the windows to see stars for a PS1 COAS alinement.

Jim Lovell (CDR)

Okay, in this attitude, Jack, that we're pitching around, I cannot use the AOT to see stars. We—we're just not able to see them at all. Now we may be able to maneuver off in yaw or—and/or roll and see stars. Right now, we haven't been able to. The AOT is useless. The command module structure is just radiating too much light into the—into the telescope.

Jack Lousma (CAPCOM)

Okay, and how about using the service module to cast a shadow on the commander's window? If you do that, can you see stars for a COAS alinement?

Jim Lovell (CDR)

We could give that a try, Jack, although I don't know how successful it will be. We tried to do it—The light shines off our quads which makes it difficult to see stars. We do have the Earth and the Moon, if that can be of assistance.

Fred Haise (LMP)

Another problem—Right now, Jack, I'm looking out the right window and it's pretty dark out that window but there are about a thousand or so false stars out here from—left over from some of the debris. It's hard to discern what's real and not real.

Jack Lousma (CAPCOM)

Okay. That's good information and during the time that we see you're continuing to pitch, if you ever get in a position where you think the AOT might be of some use, we'd like you to periodically look out of it and see if you can see some stars that would enable us to get a P52.

Jim Lovell (CDR)

Okay, will do. And also, let me ask you a question. In this configuration, docked, we have to use the TTCA to control pitch and roll. And, just how much can we use that without really changing our trajectory? We only have 60 miles to play with.

Jack Lousma (CAPCOM)

Roger, we'll put that to them.

Fred Haise (LMP)

Okay, Jack, are you ready to go to work with me on the 2-hour DPS activation and contingency book, page 1?

Jack Lousma (CAPCOM)

Roger, we're ready to go.

Fred Haise (LMP)

Okay. Item one, we can—one through five, we can scratch off, as done. Is that correct?

Jack Lousma (CAPCOM)

Okay, Fred, let's go ahead. Step 1, page 1. Everybody's listening.

Fred Haise (LMP)

Okay, I've looked around, and I've essentially done steps 1 through 5 with the exception of floodlights and utility lights and I think we'll just do without those.

Fred Haise (LMP)

Okay, on EPS activation, we're through step—we're through that—bottom of that page. That's all done.

Fred Haise (LMP)

Okay, in essence, we've circumvented step 4, and we're not sitting with all 4 aps—descent BATs on high-voltage taps, so I'll scratch off step 4.

Jack Lousma (CAPCOM)

Roger, and in step 5, we want to leave INVERTER 1 circuit breaker OPEN.

Fred Haise (LMP)

Roger. In step 5, we'll leave INVERTER 1 CB OPEN.

Fred Haise (LMP)

Okay, for the time being, our mission timer is the computer so, mission timer activation scratch off.

Fred Haise (LMP)

Okay. We've done the primary glycol loop activation.

Jack Lousma (CAPCOM)

Aquarius, we recommend you leave the caution and warning off on page 3.

Fred Haise (LMP)

Okay. I was going to say that next. Page 3, we'll just scratch item 1. And item 2, I've already got the RCS heaters on. And I don't know if I gave you the time or you got the time on the PRIMARY EVAP FLOW number 1, OPEN.

Fred Haise (LMP)

Okay. Let's go to the CB pages now.

Jack Lousma (CAPCOM)

Fred-o, did you close the engine control breaker in panel 11?

Fred Haise (LMP)

What control is that, Jack?

Jack Lousma (CAPCOM)

Did you close the S and C engine control breaker on panel 11? As we got step 1 there on page 3.

Fred Haise (LMP)

Okay. Okay, yes, the EPS DESCENT ECA CONTROL breaker is CLOSED on 11.

Jack Lousma (CAPCOM)

Roger, and how about the—on panel 11, S and C ENGINE CONTROL, CLOSED? AFT OMNI, Fred.

Fred Haise (LMP)

Okay. We're AFT OMNI, and we have the S and C ENGINE CONTROL breaker CLOSED.

Jack Lousma (CAPCOM)

Roger. Let's go on with the circuit breaker panel checkout.

Fred Haise (LMP)

Okay. I'll just give you—I think it'll be easier to give you what I got in. Okay, in the top row on 11, we have the four AC BUS TIE breakers IN and the AC BUS VOLTS breaker IN, and that's it. Second row, we have the four TCA breakers IN. We have the GASTA under FLIGHT DISPLAYS and COMMANDER's FDAI. And likewise under AC BUS A, we have a GASTA and a COMMANDER FDAI breaker IN. That's it. On row 3, we have a SIGNAL CONDITIONER 1. We have the ATCA (PGNS). We have the ENGINE CONTROL breaker, ATTITUDE DIRECT CONTROL breaker, and the—under LIGHTING, ANUN/DOCK/COMPONENT breaker IN. And one other, ED LOGIC POWER A—ED LOGIC POWER A is also IN.

Fred Haise (LMP)

Okay, under the fourth—fourth row, we got all the QUAD HEATER breakers IN, SUIT FAN 1. Under ECS, GLYCOL 1 and 2; and under COMM, we have COMMANDER AUDIO IN, and PGNSs LGC/DSKY, IMU STANDBY, IMU OPERATE, and that's it. Okay, in the bottom row, EPS, we have the BAT FEED TIE both IN, and we have the CROSS TIE BALANCE LOADS IN, the X LUNAR BUS TIE, DESCENT ECA CONTROL, DESCENT ECA, and the DC BUS VOLTs breaker.

Jack Swigert (CMP)

That completes it for panel 11. Okay. Stand by. Okay.

Fred Haise (LMP)

As I see it, some of the short ones are—we need the DECA GIMBAL in sooner or later.

Jack Lousma (CAPCOM)

That's affirmed. Close the DECA GIMBAL.

Fred Haise (LMP)

And probably—Okay, DECA GIMBAL, and sooner or later, we're going to need DECA POWER, I guess, also.

Jack Lousma (CAPCOM)

All right, DECA POWER will come up later in the procedure, Fred-o.

Jack Lousma (CAPCOM)

Aquarius, Houston. On your circuit breaker checklist, on panel 11 and 16, we want you to configure the panels as outlined in the checklist.

Fred Haise (LMP)

Okay. You want us to configure as per checklist. Okay. We'll do that.

Jack Lousma (CAPCOM)

That's right. Close the black ones and open the white ones.

Fred Haise (LMP)

Yes. I think we can manage that.

Jim Lovell (CDR)

With the activation power up, we're starting right now.

Jim Lovell (CDR)

Houston, we might as well leave our RCS TCAs IN, right?

Jack Lousma (CAPCOM)

Affirmative, Jim. Leave your RCS TCAs in —

Fred Haise (LMP)

— Yes. I used my Pentel pen and made those white ones black ones.

Jack Lousma (CAPCOM)

Roger. Same on 16, Fred.

Jim Lovell (CDR)

And you might look there, Houston, to see what circuit breakers aren't required, like the tape recorder.

Jack Lousma (CAPCOM)

Okay, Jim. On panel 11 over there, you can also leave open the RENDEZVOUS HEATER breaker and the LANDING RADAR HEATER breaker, in addition to the tape recorder.

Fred Haise (LMP)

I'm leaving a few in, Jack, too, like the SUIT FAN 1 is still IN, RCS SYSTEM is still IN, the TCAs. ATTITUDE DIRECT CONTROL is IN.

Jim Lovell (CDR)

How about if I leave the VHF A and B OFF?

Jack Lousma (CAPCOM)

Okay. We can leave the VHF powered down, too.

Jim Lovell (CDR)

And, do you want the SECONDARY S-BAND?

Jack Lousma (CAPCOM)

Negative on SECONDARY S-BAND. Leave them open.

Jim Lovell (CDR)

UP DATA LINK is IN. Do you want that in or out?

Jack Lousma (CAPCOM)

Leave the UP DATA LINK open. We'll call for it when we want you to put it in.

Fred Haise (LMP)

Okay, Jack, on panel 11 on the top row, do you really want the PROPULSION PQGS and ASCENT HELIUM REGs in?

Fred Haise (LMP)

And, also the SYSTEM ENGINEER X- POINTER breaker.

Jack Lousma (CAPCOM)

Roger. Negative on the PQGS. Negative on the ASCENT HELIUM REG, and negative on the CROSS-POINTER.

Fred Haise (LMP)

Okay. On the second row, I'm going to leave the FLOODLIGHT breaker open.

Fred Haise (LMP)

And we're again up to—Do you want the CWEA enabled?

Fred Haise (LMP)

Okay. Since we're—are we going to power up the AGS or should I concern myself with the ATCA breaker?

Jack Lousma (CAPCOM)

Negative on the AGS. However, Fred, we need the ATCA breaker in.

Fred Haise (LMP)

Okay. ATCA breakers IN. Yes. I guess for the backup power supply. Hey, how about ATCA AGS.

Fred Haise (LMP)

And I'm leaving the SUIT FLOW CONTROL breaker open.

Jack Lousma (CAPCOM)

Let's close the SUIT FLOW CONTROL breaker —

Jack Lousma (CAPCOM)

— so it doesn't take any current.

Fred Haise (LMP)

Okay. Without suits, it doesn't do us much good either though.

Fred Haise (LMP)

Okay. And are we going to continue to be able to operate off the OMNIs, Jack. So can I leave the S-band antenna powered down?

Jack Lousma (CAPCOM)

Okay, Fred-o. We don't plan to use the steerable antenna, although we want to leave the heaters on. So it looks you ought to open up COMM S-BAND ANTENNA, but leave S-BAND ANTENNA HEATERS closed.

Fred Haise (LMP)

Roger. COMM S-BAND is OPEN, S-BAND HEATER breaker is still CLOSED.

Fred Haise (LMP)

And, on the bottom row, Jack, I'm going to leave the HEATER DISPLAY breaker out, which we had pulled before, and EPS DISPLAY. But I question, do we want the ASCENT ECA breaker in, as prescribed?

Jack Lousma (CAPCOM)

Stand by. That's a negative on the ASCENT ECA breaker. Leave it open.

Jack Lousma (CAPCOM)

And, Aquarius, we need P00 and DATA —

Jack Lousma (CAPCOM)

— and we'll give you state vector and target load.

Fred Haise (LMP)

Okay. We need the UP LINK breaker in then now.

Jim Lovell (CDR)

Okay. And, Jack, will you give us that—how about the ORDEAL breaker? Can I pull that? We don't need that, do we?

Jack Lousma (CAPCOM)

Negative on the ORDEAL. Leave it open.

Fred Haise (LMP)

And how about the ASCENT ECA breaker on panel 11? Jim has it in over there.

Jack Lousma (CAPCOM)

And panel 11 ASCENT ECA can be open.

Jack Lousma (CAPCOM)

Okay, Aquarius. We're GO on the circuit breaker configuration as you have it now.

Unidentified crew member

Roger.

Jack Lousma (CAPCOM)

And, Aquarius, tests in the simulator just showed that if you want to let the PGNS DAP hold your attitude for you, it will.

Jim Lovell (CDR)

And, Jack, because it will take quite a while to get back to the attitude, I think we ought to think about going there very shortly.

Jack Lousma (CAPCOM)

Roger. I have a pad for you. I have a P30 maneuver pad.

Fred Haise (LMP)

Go right ahead, Jack.

Jack Lousma (CAPCOM)

Okay. We want you to hold your maneuver until we finish making the load. We haven't completed it yet. Are you ready to copy P30 maneuver pad?

Jack Lousma (CAPCOM)

Okay. Here we go. The purpose is midcourse correction for free return. NOUN 33: 061:29:42.84; minus 0021.3, plus 0004.1, minus 0031.2; HA and HP are NA; DELTA-V 0038.0; 031, 120, 298, minus 00213, plus 00041, minus 00312; COAS NA. And I have your LM GDA angles. Pitch 5.86, roll 6.75. Your DPS throttling, 5 seconds at 10 percent, burn the rest at 40 percent. Your ullage will be two jets for 10 seconds.

Fred Haise (LMP)

Okay, Jack, we have a P30 maneuver pad, a midcourse for free return. NOUN 33: 061:29:42.84; minus 0021.3, plus 004.1, minus 0031.2; HA and HP N/A; DELTA-VR 0038.0; 031, 120, 298; minus 00213, plus 00041, minus 00312. COAS N/A; GDA angles; pitch 5.86, roll 6.75; DPS throttle 5 seconds at 10 percent; burn the rest at 40 percent. And we need a two-jet, 10-second ullage.

Jack Lousma (CAPCOM)

That's a good readback, Fred. I'd like to verify, however, in NOUN 81, in VY, it's plus three balls 41.

Fred Haise (LMP)

Okay. NOUN 81, VY is plus 0004.1.

Jack Lousma (CAPCOM)

Good readback. Let's press on with the checklist.

Jim Lovell (CDR)

Okay. And, Jack, find out about using TTCA to maneuver with.

Jack Lousma (CAPCOM)

Okay. We're finished with the computer, it's yours, and we recommend using the TTCA to maneuver with.

Fred Haise (LMP)

Okay, I'm back on the checklist, page 6. Jack, under PGNS turn-on and self-test. We've done everything except the self test here on this page. Do you want to do that at this time?

Jack Lousma (CAPCOM)

Okay. Aquarius, negative on the PGNS self test.

Fred Haise (LMP)

Okay. I'll scratch page 6 and on page 7, we're not going to activate the—or rather we had the S-band activated, ECS Activation I have all done. And, at the bottom of the page, the docked IMU coarse aline is done.

Fred Haise (LMP)

We've—Okay, we've also completed, I guess in essence, all of page 8.

Jack Lousma (CAPCOM)

That's affirmative and page 9 to boot. Scratch VHF. We've done the Tephems.

Fred Haise (LMP)

Okay. You've updated it, that's right. We cranked in the time.

Jim Lovell (CDR)

And, Houston, let's go to activation—or get into page 10 and see what we did there.

Jack Lousma (CAPCOM)

Okay. The only item on page 10 is to deploy the landing gear.

Jim Lovell (CDR)

Okay, we'll do that now.

Fred Haise (LMP)

Okay. The landing gear are down and locked, Jack, and looking ahead now at page 11, we've done all of that.

Jack Lousma (CAPCOM)

We verify that. Page 12.

Fred Haise (LMP)

Okay, and I assume in amongst all those numbers you pumped up, we got a REFSMMAT and STATE VECTOR, is that correct?

Jack Lousma (CAPCOM)

That's affirmative. You've got that. So you can delete page 12.

Fred Haise (LMP)

Hey, on 13, you've read us up the fine aline angles and we've cranked those in.

Fred Haise (LMP)

Okay, so now we're up to—we've got to do DAP set, the gimbal/throttle test.

Jack Lousma (CAPCOM)

That's—Okay, Aquarius. We recommend omitting the DAP set, gimbal/throttle test—just make sure the gim—DECA POWER and DECA GIMBAL circuit breakers are closed.

Fred Haise (LMP)

Okay, we're going to proceed now with the DAP set, gimbal/throttle test, is that correct? Or did you say delete it?

Jack Lousma (CAPCOM)

Aquarius, delete the DAP set, gimbal/throttle test. Just ensure that the DECA POWER and the DECA GIMBAL are closed.

Jim Lovell (CDR)

Okay. Houston, DECA POWER is OPEN at this time. Do you want me to close it?

Jack Lousma (CAPCOM)

Affirmative, Jim. Close the DECA POWER.

Jim Lovell (CDR)

It's CLOSED. We deleted that.

Fred Haise (LMP)

Okay. Also out of that list, Jack, we need the COMMANDER's THROTTLE set to THROTTLE and MIN.

Fred Haise (LMP)

Houston, if I recall the launch set of the gimbals, the GDAs are not correct here, and where are we going to get those set for the burn?

Jack Lousma (CAPCOM)

Okay. Here's the word on the DAP set, gimbal/ throttle test. Let's do step 1 and step 2, and that'll get our gimbal set.

Fred Haise (LMP)

Okay, Jack, we're going to have to back up on this, if we're going to follow the procedure here, which has us go MODE CONTROL; PGNS, AUTO, we're going to have to pull the TCA breakers to keep from firing jets.

Jack Lousma (CAPCOM)

Stand by on step 1, Fred. We're getting the word for you. How do you like this SIM?

Jack Lousma (CAPCOM)

Okay, Aquarius, we recommend you do the DAP set and gimbal/throttle test as per the checklist. Go PGNS AUTO and proceed.

Jim Lovell (CDR)

Well, we're going to fire our thrusters as soon as we go to AUTO because we've got those thrusters in—the thruster circuit breakers. Do you want us to do that and stop?

Jack Lousma (CAPCOM)

Okay, Aquarius, we're recommending you go to AUTO. Let the thrusters fire and settle down and proceed with the test.

Jack Lousma (CAPCOM)

Roger, your DAP is set, you're in wide deadband. That ought to do the trick.

Jack Lousma (CAPCOM)

Okay, we're looking at it, Aquarius. We're ready to proceed with the test.

Fred Haise (LMP)

Okay, we're proceeding.

Fred Haise (LMP)

Okay, and Houston, you—you're looking at the weights now. Those are still good, right?

Jack Lousma (CAPCOM)

You're GO on the weights.

Jack Lousma (CAPCOM)

Aquarius, Houston. We'd like you to recycle on the DAP load and change your DAP to 32021. Over.

Jack Lousma (CAPCOM)

Okay, Aquarius. We're looking at your gimbal and we notice that we got a four-jet ullage loaded in the DAP and we gave you two jets on the pad. But, let's go with what we've got loaded. It'll be a four-jet ullage.

Fred Haise (LMP)

Okay, Houston. How does the GDAs look now?

Jack Lousma (CAPCOM)

The GDAs are GO as they are. Press on.

Jim Lovell (CDR)

Okay, Houston, we're going to do the DPS pressurization and checkout.

Jack Lousma (CAPCOM)

Okay, your gimbals are within 0.3 and we're ready for the DPS pressurization and checkout.
