Spacelog Apollo 13

Okay. Continue, Vance.

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.

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.

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

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

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.

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

Good work, Vance.

Thank you.

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.

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

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

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

Yes.

I'll get 16 NOUN 20 out.

Do you have me move AUTO TRANSFER this time?

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

You don't, do you?

Yes.

Let's give them a call, panel 11.

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

Roger. Loud and clear, Fred.

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

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

Okay. Pull it, Jim.

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

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

Okay. I'm going to pull inverter 1.

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

Okay.

Roger. —

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

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

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

Vance, Aquarius.

Roger. Go ahead, Fred.

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?

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.

Okay.

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.

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?

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

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.

With me?

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?

Here we go.

… the battery. …

Do you know what the plus-X thrusters are?

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

Aquarius, Houston. Over.

Go ahead.

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.

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.

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

Roger.

Yes. Those are the plus-X, right?

Houston, Aquarius

Go ahead, Aquarius.

Ah -

Go ahead.

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?

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

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

I just did.

Okay.

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

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

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

It's going slightly.

So is this one.

Yes. You got a ways to go in pitch.

Yes.

… 80.

You want to rest a little bit?

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

We're now in the hands of tracking.

Yes. It looks different than before.

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

Well, you can see where —

You almost can see —

— See Ptolemaeus, Althonsus—There's Herschel.

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

Aquarius, Houston.

Go ahead, Houston.

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.

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

Okay.

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

Roger.

We ought to start working on that MOD right now.

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.
