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.
- 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.

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.
- 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)
-
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.
- 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?

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.
- 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)
-
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.
- 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.
- Jim Lovell (CDR)
-
All right. CO2. Our CO2 value is getting high. We had a DPS ECS light and a blinking component light.
- 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, 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.
