Spacelog Apollo 13

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?

Okay. Aquarius, negative on the PGNS self test.

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.

Roger.

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

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

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

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

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

Okay, we'll do that now.

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

We verify that. Page 12.

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

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

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

Affirmative.

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

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.

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

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

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

Affirmative, Jim. Close the DECA POWER.

It's CLOSED. We deleted that.

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

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?

Stand by 1.

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.

Roger.

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.

Stand by, Fred.

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

It's a beauty.

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

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?

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

We're in PGNS AUTO.

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

Roger.

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

Okay, we're proceeding.

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

You're GO on the weights.

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.

Okay.

Okay, Houston. How does the GDAs look now?

The GDAs are GO as they are. Press on.

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

Stand by 1.

And, in the event that you have to do a manual takeover, turn the ENGINE GIMBAL OFF, MODE CONTROL to ATTITUDE HOLD, and use the hand—use the TTCA.

Roger.

Okay, 1 plus 30 to burn.

Roger.

Okay, MASTER ARM's ON; 1 minute.

Roger, Aquarius. You're GO for the burn.

40 percent.

Okay, Aquarius. You're looking good.

AUTO shutdown.

Okay. You're looking at 1685 now, Jack.

Okay. You're GO in the residuals, proceed.

Okay. When you say GO on the residuals, you mean don't trim them. Is that right?

That's affirmative. No trim required.

Roger.

Okay.

Aquarius, check your MASTER ARM OFF, please.

Okay, Houston. Burn's complete. Now we have to talk about powerdown, and what do you want us to do with the PGNS?

Roger. We're looking at that right now, and you'll be the first one to get the word.

And, Houston, it's doubtful right now whether we'll be able to see the stars in this configuration. The only way we could possibly get alinement is with the Earth and the terminator or the Moon and its terminator and I'd sure like to have you look at a powerdown—keeping the PGNS if at all possible.

Roger, Jim. We'll get the word for you.

And, Houston, we're in an ATT HOLD mode, can we turn off the buses?

Okay, Aquarius. We're working on what's going to happen next. In the meantime, we'd like to take some high-power items off the line, so on panel 11, open DECA POWER, and open DECA GIMBAL. On 16, open the ATCA breaker.

Okay, on 11, we got DECA POWER, DECA GIMBAL, OPEN. On 16, we got the ATCA breaker OPEN.
