Jim Lovell (CDR)

Okay. Continue, Vance.

Vance Brand (CAPCOM)

Okay. Next page, power 7, panel 16. First row, close the four QUAD TCA circuit breakers, that is, QUAD 1, TCA; QUAD 2, QUAD 3, and QUAD 4 TCA. Okay. Rows 2, 3, and 4 are okay.

Fred Haise (LMP)

Okay. Panel 16, top row, we want to close QUAD 1 through 4 TCA breakers, and you're saying the other three rows are as is. Again, I have the exception the ASCENT ECA CONTROL on 16 should also be open.

Vance Brand (CAPCOM)

Okay. We concur on that, and we have a late arrival in row 3. Stand by.

Vance Brand (CAPCOM)

Okay, Fred. One addition, third row. The S-BAND POWER AMP. Request that you pull that circuit breaker and leave the switch in PRIMARY.

Fred Haise (LMP)

Okay. Yes, that's the way we were doing it before. I'll pull the POWER AMP CB, and then I'll go back to the first stage and put the POWER AMP to PRIME.

Vance Brand (CAPCOM)

That's correct; that should be changed back to PRIME. And that's—that's it.

Fred Haise (LMP)

RESET, OFF and LOW. Okay. Lighting bus off; EXTERIOR LIGHTING is off. Okay. You want to get your breakers, Jim? We ought to probably go back to that wide deadband.

Jim Lovell (CDR)

Okay. The BUS TIE INVERTERs are coming off the line.

Jack Swigert (CMP)

Yes. Go ahead. Sorry, I put the switch off, that'll kill caution and warning.

Jim Lovell (CDR)

Okay. Let's see. So we're going to lose the ball again.

Fred Haise (LMP)

I'll get 16 NOUN 20 out.

Jim Lovell (CDR)

Do you have me move AUTO TRANSFER this time?

Jim Lovell (CDR)

Why do I still have a VHF-A receiver off?

Jim Lovell (CDR)

Let's give them a call, panel 11.

Fred Haise (LMP)

Okay, Vance. I'm on—Do you read me now, hot mike?

Vance Brand (CAPCOM)

Roger. Loud and clear, Fred.

Fred Haise (LMP)

Okay. Jim just noticed we got a VHF breaker in on panel 11 still, I think, that probably should be opened.

Vance Brand (CAPCOM)

Okay. That's affirmative. Pull the VHF-A receiver.

Jim Lovell (CDR)

I got it already. Okay. Now, why are we putting the cabin fan on?

Jim Lovell (CDR)

Oh, oh, oh. Oh, yes. Okay.

Jim Lovell (CDR)

Okay. I'm going to pull inverter 1.

Fred Haise (LMP)

Okay. Not very long since they had the switch off on you, anyway.

Jim Lovell (CDR)

— but my only question is, I got the CROSS TIE BUS circuit breaker in? Could be—Yes, this one right here.

Fred Haise (LMP)

Good line. It's on. Because that line is open.

Fred Haise (LMP)

I'll look over at that caution in a minute.

Fred Haise (LMP)

Yes. We've managed the first 30 hours or so here without the caution and warning; we don't need to keep it up now, do we?

Vance Brand (CAPCOM)

Okay, Fred. That's one that we're leaving up until the PTC is established. We have a procedure for PTC to try with you, which we're hopeful will work pretty well. And I'll read that up as soon as you get what you're doing now done.

Jim Lovell (CDR)

Why don't you go ahead, and I'll get this PTC procedure. It's by the photo log, and I'll just get that.

Fred Haise (LMP)

And one other question, Houston. You really want to pull the ASA breaker? You want to give up the AGS probably for good now, huh?

Jim Lovell (CDR)

Houston, I'm standing by to copy the PTC procedures.

Vance Brand (CAPCOM)

Okay. I'll get back with you on your question in a minute, Fred. New, here comes the PTC procedure. Step 1, GUIDANCE CONTROL to PGNS; two MODE CONTROL, ATT HOLD; VERB 76, ENTER; maneuver to PTC attitude; and that incidentally is roll 0, pitch 90, and present yaw. We realize you can't monitor that on your FDAI, but you can on a verb, with a VERB 16 NOUN 20.

Jim Lovell (CDR)

Roger. GUIDANCE CONTROL, PGNS; MODE CONTROL, ATT HOLD, VERB 76, ENTER; maneuver to PTC attitude which is roll 0, pitch 90, and yaw, which is the present yaw. Is that correct?

Vance Brand (CAPCOM)

That's correct. Okay. Next. Mode—at—When you're established at the attitude, MODE CONTROL AUTO. Key in VERB 16 NOUN 20 to monitor rates; when less than 0.1 degree a second, rate in all—in each axis, then disable plus-X thrusters. Okay. Next VERB 25, NOUN 07, ENTER; 1257, ENTER; 252, ENTER; 1, ENTER; VERB 77, ENTER; VERB 48, ENTER; put in the DAR 22110 and PROCEED; VERB 34, ENTER; then VERB 16, NOUN 20; and monitor rates. On rates less than 0.01 degrees per second in all axis: VERB 76, ENTER; MODE CONTROL, ATT HOLD; then 30 clicks of right yaw to start the maneuver. Over.

Jim Lovell (CDR)

Okay, Vance. PTC procedure: GUIDANCE CONTROL, PGNS; MODE CONTROL, ATT HOLD; VERB 76, ENTER; maneuver to PTC attitude; roll 0, pitch 90, yaw 0; my ball now, of course, is inoperative, so I'll have to get that on the DSKY. The 5 is MODE CONTROL, AUTO; 6: VERB 16, NOUN 20, monitor rates; rates less that 1 degree per second in each axis, disable, and I didn't hear that last part. The next one was VERB 25, NOUN 07, ENTER; 1257, ENTER; 252, ENTER; 1, ENTER; VERB 77, ENTER; VERB 48, ENTER; 22110, PROCEED; VERB 34, ENTER; VERB 16, NOUN 20, ENTER; monitor rates. Rates less than 0.01 degrees per second in all axis. VERB 76, ENTER; MODE CONTROL, ATT HOLD; then 30 clicks of right yaw to stop—to start—maneuvers

Vance Brand (CAPCOM)

Roger. That's correct, Jim. To—to answer your questions and correct one point, yaw should be your present yaw, whatever it is, and that's up with roll 0, pitch 90, present yaw. The other thing is, you said disable and you didn't hear the rest. That's disable plus-X thrusters. And, finally, near the end, the 22110 referred to DAP loading.

Jim Lovell (CDR)

Roger. Now, to maneuver to PTC roll 0, pitch 90 and yaw in—and pitch in here, roll is here. Yaw—whatever yaw we have in. Okay, Vance. In our initial maneuver to PTC attitude, I am going to have to use—to display 16 20 and I'll have to use the TTCA to get there.

Vance Brand (CAPCOM)

Jim, Roger. Your use of the TC—TTCA and just a reminder that in maneuvering that—that—that roll is in R3 and yaw is in R1.

Expand selection up Contract selection down Close
Jim Lovell (CDR)

That's affirm. And I'm going to take out roll first to get it zero and then I'm going to take care of pitch.

Jim Lovell (CDR)

Okay. GUIDANCE CONTROL, PGNS; MODE CONTROL to ATT HOLD. VERB 73 clears. Okay. We've got to get that out. … it stopped moving.

Jim Lovell (CDR)

Do you know what the plus-X thrusters are?

Jim Lovell (CDR)

Yes, okay. I just wanted to make sure you do. I got them over here.

Vance Brand (CAPCOM)

Aquarius, Houston. Over.

Vance Brand (CAPCOM)

Okay. A couple of things, Jim. One is that you can use the TTCAs to maneuver, but you're going to save a lot of fuel if you'd try MINIMUM IMPULSE. So, that might be a better recommendation. The other thing is, we'd like to give you a GO before you disable the plus-X thrusters, and before you do a VERB 76, and MODE CONTROL to ATT HOLD. Over.

Jim Lovell (CDR)

Okay; understand. You want a GO before I—I'm—Of course, I just did a 76, and the MODE CONTROL is in ATT HOLD, at this time. But, this is later on down.

Vance Brand (CAPCOM)

Yes. All we wanted to do was take a look at things before you disabled the plus-X thrusters, and before you go to MIN IMPULSE at the end there—that VERB 76, ENTER; MODE CONTROL, ATT HOLD.

Jim Lovell (CDR)

Roger. Understand. And I'm maneuvering my roll now to zero.

Jim Lovell (CDR)

Yes. Those are the plus-X, right?

Fred Haise (LMP)

In what fashion did you want us to disable those plus-X thrusters? Just pulling those appropriate TCA breakers, or did you want to actually go in and mask those jets?

Vance Brand (CAPCOM)

Okay, Fred. We didn't explain that. The VERB 25, NOUN 07, ENTER sequence does that.

Fred Haise (LMP)

Okay. I didn't read the whole procedure. Jim just mentioned he wanted to disable plus-X.

Fred Haise (LMP)

And, Vance, are you still trying to get me an answer on that—pulling that ASA breaker?

Vance Brand (CAPCOM)

That's affirm, Fred. This—The word here is, pull it.

Fred Haise (LMP)

Okay. Sure didn't get much work out of the AGS this time.

Fred Haise (LMP)

Yes. You got a ways to go in pitch.

Jim Lovell (CDR)

You want to rest a little bit?

Fred Haise (LMP)

What time is it, 9:30? Yes. I got about what? I think I got about 10.

Jim Lovell (CDR)

We're now in the hands of tracking.

Fred Haise (LMP)

Yes. It looks different than before.

Fred Haise (LMP)

Hard to do P37s in the LM. Hard to do a P37 in the LM.

Jim Lovell (CDR)

Well, you can see where —

Fred Haise (LMP)

You almost can see —

Jim Lovell (CDR)

— See Ptolemaeus, Althonsus—There's Herschel.

Fred Haise (LMP)

Yes, you can barely see it in the corner there.

Vance Brand (CAPCOM)

Okay. Just some info. We're working up a procedure for you to use to—to use command module LiOH canisters to connect to your hoses—the outlet hoses in the LM so that, as time passes in the mission, you can continue scrubbing the LM atmosphere. And this whole thing requires modifying a kit so that you can attach the hose modifying a LiOH canister, so you can attach the hose to it. So, sometime in the future, we will be coming up to you with that procedure. Second point—Second point in, we're standing by to watch your maneuver for the PTC procedure. Over.

Jim Lovell (CDR)

Okay. I'm in process now, Vance, of maneuvering to zero yaw, 90-degree pitch, using MINIMUM IMPULSE.

Fred Haise (LMP)

And, Vance, I assume it had also been brought up that we got two extra secondary cartridges—one in each PLSS.

Jim Lovell (CDR)

We ought to start working on that MOD right now.

Vance Brand (CAPCOM)

Yes. We wish we could send you a kit and it would be kind of like putting a model airplane together or something. As it turns out, this contraption will look like a mailbox when you get it all put together.

Fred Haise (LMP)

What do we make it out of, Vance?

Fred Haise (LMP)

— How about planning a rendezvous procedure?

Vance Brand (CAPCOM)

— with a plastic roof.

Jim Lovell (CDR)

Just for information, Houston, during—just prior to going around the Moon, we saw a lot of debris that was floating by us, including some—one rather large piece looked like the wrapping off of a line of some sort that is—still is with us.

Jim Lovell (CDR)

Even after our free-return midcourse yesterday.

Jim Lovell (CDR)

No matter what I do, I can't stop that. Roll either way won't do it.

Fred Haise (LMP)

Well, I don't see any way around it, Jim. It sure doesn't seem to be doing much, does it? It won't go down.

Jim Lovell (CDR)

I don't know. I wonder if they tried that in the simulator. I can't seem to get roll to go up. It goes down on me, no matter how I hit the controllers.

Jim Lovell (CDR)

You can really see a change in rate?

Fred Haise (LMP)

… jar here, see if it'll couple in roll.

Jim Lovell (CDR)

I don't know what caused it.

Jim Lovell (CDR)

Here we still have 67-percent fuel level. I wonder how come they didn't … DELTA-V curve?

Vance Brand (CAPCOM)

Jim, we don't have any data on your movements right now. How does it look like this procedure's going to work out so far as getting an attitude set up, the first part of the procedure?

Jim Lovell (CDR)

Well, Vance, I've been trying to use MINIMUM IMPULSE only attitude control to get my roll and yaw—the roll and pitch, rather. But, with the attitude control only in this configuration, I—I can't command these—the roll the way I want to. So, I had to go to TTCA to get my roll to build up towards zero, it was going—decreasing towards 270. I really don't know what the combination is in the attitude control, that you can get the control to pitch and roll the way you want it to. You've got to use the TTCA.

Jim Lovell (CDR)

I now have both pitch and yaw—or pitch and roll going toward the designated amounts, now passing through 23 degrees in pitch, and I'm going up past 321 degrees in roll. And I am letting go that direction and when I get there, 90 in pitch and zero in roll, I'll go to AUTO and damp the rates.

Jim Lovell (CDR)

Get a little sleep? That's okay.

Jim Lovell (CDR)

We've got to rig up a method of using those lithium hydroxide canisters.

Fred Haise (LMP)

Okay, Houston. We just got a MASTER ALARM and an ECS light. I take it the partial pressure CO2 is—Yes—That's what tripped it.

Vance Brand (CAPCOM)

Aquarius, Houston. Say again.

Jim Lovell (CDR)

All right. CO2. Our CO2 value is getting high. We had a DPS ECS light and a blinking component light.

Vance Brand (CAPCOM)

Stand by on that PTC O2.

Jim Lovell (CDR)

Hello, Houston. How do you read? Over.

Vance Brand (CAPCOM)

Okay. Read you loud and clear now, Jim.

Jim Lovell (CDR)

Okay. Did you hear what I just said about the ECS light and the blinking CO2 component light?

Vance Brand (CAPCOM)

Okay. We got that and—Stand by 1.

Jim Lovell (CDR)

Jack, we might have to have you rig up this CO2 rig they're talking about.

Vance Brand (CAPCOM)

Go ahead. Houston. Over.

Jack Swigert (CMP)

Oh! We've got a long ways to go.

Vance Brand (CAPCOM)

Okay, Jim. We're going to have to get back with you in a couple of minutes on whether or not we switch over at this time to your other canister. Second point, it might help in setting up this PTC if you concentrate on roll first, and get that going; and then work on pitch, when roll is established, and sort of take whatever yaw you get.

Jim Lovell (CDR)

Okay. Vance, I tried that but when I start doing roll only I get pitch coupled in with it. But both of them rolling up toward this desired amount, though. I'm up to 46 and in pitch and 326 in roll.

Vance Brand (CAPCOM)

Okay. Understand you've tried it.

Jim Lovell (CDR)

Once I get roll zeroed, I don't think it'll be too bad.

Unidentified crew member

(Laughter)

Jim Lovell (CDR)

So what did they put on my LEVA?

Fred Haise (LMP)

No. He didn't want it. There she goes, gang. The Moon.

Vance Brand (CAPCOM)

Okay, Jim. Since the first recommendation on how to maneuver PTC didn't work out, we have another one. And you might try this. Put yaw at zero, then start the roll, and the pitch after that.

Vance Brand (CAPCOM)

Yes. I do now. Go ahead.

Fred Haise (LMP)

Key moment Mission control describes the 'mailbox' CO2 scrubbers: Okay. You guys just tell me what sort of material you had in mind to build this mailbox out of, and Jack and I will go to work on trying to construct that thing. Assume we'll use the space-age baling wire or the gray tape?

Vance Brand (CAPCOM)

That's affirm. We have a lengthy procedure here; but, in short, you use plastic as a covering for the whole thing. You put some kind of a stiffener at the top so the plastic doesn't suck against the LOI—LiOH enter—entrance side. You'll—You need gray tape to stick the whole thing together, and you need something like a sock to put in the—the bottom so that the outlet side is plugged up. As it turns out, the flow is rather U-shaped through the cartridge, Fred. It, if you plug up the bottom, it comes in one side of the top and goes out the other.

Fred Haise (LMP)

Okay. (Sigh) Hold on a minute. Let—Let us go get a cartridge and with it in hand, I'll speak to you some more.

Vance Brand (CAPCOM)

Aquarius, Houston. Over.

Jim Lovell (CDR)

Okay, Vance. Go ahead.

Vance Brand (CAPCOM)

Okay. Really, I think we should give you a more detailed procedure on that; and, in general, those are the materials that are to be used, but let us get back with a detailed procedure on how to make this cartridge arrangement work.

Jim Lovell (CDR)

And to answer your question about PTC, Vance, it's rather difficult to use yaw in zero right away. So what I'm doing, yaw is working toward zero right now. Pitch is working toward 90, and roll is working toward—zero. So, we—We're just going to take some time to get there, that's all.

Vance Brand (CAPCOM)

Roger. Quite a bit of noise now. I understand you're still having a problem getting there with the PTC.

Jim Lovell (CDR)

We are getting there slowly.

Vance Brand (CAPCOM)

Aquarius, Houston. Let's try FORWARD OMNI.

Fred Haise (LMP)

I don't know, it looks …

Fred Haise (LMP)

I don't know, it looks that way.

Okay, Houston. How do you read, now?

Fred Haise (LMP)

Houston, how do you read?

Vance Brand (CAPCOM)

Loud and clear, now. Go ahead.

Fred Haise (LMP)

Okay. I switched to FORWARD OMNI, now.

Jim Lovell (CDR)

They're … off. They can't stop pitch.

Jim Lovell (CDR)

That would only use fuel.

Jim Lovell (CDR)

… and stick it around that way.

Jim Lovell (CDR)

Must have the wrong thing, there.

Fred Haise (LMP)

Oh, yes. That was pretty.

Fred Haise (LMP)

That didn't sound very good.

Jim Lovell (CDR)

They're a hell of a long ways away.

Jim Lovell (CDR)

Yes, we're not moving that fast to Earth.

Fred Haise (LMP)

Hey, we're already … this time, huh?

Fred Haise (LMP)

… to the trajectory.

Jim Lovell (CDR)

Yes, I've been trying to get roll out. Roll to zero. Just go ahead to zero, I'm going to put it in ATT HOLD. Then it'll take out yaw, leaving pitch the way it is; then we're going to pitch down.

Fred Haise (LMP)

We've got to think about when we have to start changing that canister.
