Spacelog Apollo 13

Jack, read you loud and clear.

Okay. Fine.

We show minus 8-1/2 minutes.

Roger. Houston copies.

Close —

Is that too close, Vance, or can you make out the SPS engine panel now?

We can see your fuel and oxidizer gages and hydrogen/oxygen gages at the top of the picture and the PUGS, but it isn't coming in in focus too well. It's a little dim.

Yes. I think the problem is I'm about 2 feet and it doesn't go down but to 4.

Right. We understand that's the panel right in front of your face.

Okay. Vance, stand by for the main …

Okay. We're minus 7 minutes.

Roger.

Fred, the focus is good enough that we can see the position of your four ball valves at the top of the picture for the big SPS engine.

What would you like to watch, Vance?

Hopefully, you'll see the—or we'll see the two on the left here, set A, go on here directly —

Minus 6 minutes.

MAIN BUS TIES, two, ON, Fred. Okay. SPS HELIUM VALVE, two, AUTO and checked AUTO barber pole. TVC SERVO POWER is 1, AC1/MAIN A; 2, AC2/MAIN B.

AC1/MAIN A, AC2/MAIN B.

MAIN BUS TIES, ON.

Okay. ROTATIONAL POWER NORMAL no. 2, AC.

Number 2, AC.

DIRECT, two, OFF.

DIRECT, two, OFF.

BMAGs, three, ATT 1/RATE 2.

ATT 1/RATE 2.

SPACECRAFT CONTROL, SCS.

SCS.

And arm your hand controller.

RHC armed.

Okay. Let's do a primary TVC check.

Fred, are you ready to start primary?

Okay. Go ahead on primaries.

Okay. PITCH 1, START.

Good.

YAW 1, START.

That one's good.

Thumbwheel control. 0.96 plus 0.96 minus 0.23.

That's affirm. Check MTVC.

MTVC checked. Okay.

Okay.

THC —

… C —

— TRIM returns to NEUTRAL.

Clockwise on the translation controller.

Mine? No MTVC.

No MTVC. Okay.

Starting …

Okay.

Okay.

Two balls.

Okay. Shutdown.

…

Okay. Let's get the residuals. Okay, Houston, there are the residuals.

Okay; gimbal motors.

Okay. Copy residuals.

… secondaries.

Okay. Go.

Okay. YAW 2.

Good.

PITCH 2.

That's good.

Primary.

On LOW BIT RATE. Start. Go with the primaries.

Okay. YAW 1.

That's good.

PITCH 1.

Okay.

TVC SERVO POWER, OFF.

— is OFF. Okay. Record the DELTA-V_C. You got that?

Okay. You got the—You got the DELTA-V_C in minus 3.7.

Okay. FUNCTION, OFF. MODE STANDBY.

Proceeding now.

OFF. MODE, STANDBY —

TRANSLATION HAND CONTROL POWER, OFF.

Okay. POWER OFF.

ROT POWER DIRECT, two, OFF.

Two OFF.

RATE 2.

BMAGs, RATE 2.

I'm already in low bit rate.

Okay.

Yes, we were on those … so that we had less than 0.2.

Okay. Houston copied your residuals, very low.

Okay. Fuel is 1.0; oxidizer 0.25; the OX unbalance is reading on the decrease, which doesn't mean very much, and I guess that wasn't too much for a push there, Vance. I didn't see the accelerometer do a whole lot and it was a little surprising how slowly the injector valves opened, at least on the indicators.

Roger. That was a very short burn. Request you give us a sweep across the panel when you get a chance, Fred. Let us see Jack and Jim again. Over.

Okay.

Okay, Vance, I was going to show you on—wonder if the folks might—down there might be interested in how we find out how far we're away from the Moon. Going to do that right now in program 21 here.

Okay.

I'm asking the computer how far away we are. And the computer is telling me we're 121 490 miles out.

Okay. That agrees fairly closely with our map on the wall.

I'm glad. That means you're tracking us too.

And if you didn't see our residuals, it was 0.1 X, 0.2 on Y, and 0.1 Z, and DELTA-V_C was minus 3.8.

Jack, Houston. We show you down here 121 thousand miles 520 out. So I guess we all agree.

Okay. Real good, Vance. What I'm going to do is give you a shot of Fred.

If we can get all the wiring out of the way.

The big problem here is, when you move the TV around, this wire follows you like a snake here.

Yes, we have Fred now. Looks like he has a lariat there, getting ready to rope the checklist.
