- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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)
-
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.
- Fred Haise (LMP)
-
Okay, Houston. How do you read, now?
Expand selection down Contract selection up - 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.
