Spacelog Apollo 13

Standing by for ENTER ENABLE.

ENTER ENABLE.

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.

Jack, you're in the shadow right now; we have a little bit of interference from your window, which is very bright, so we can't—I think you're smiling, but it's a little hard to tell.

…

Hey, there we go. Incidentally, we've been getting all kinds of bits of information to pass up to you. We've had baseball scores coming in, basketball. Somebody said there's 220 days, shopping days left until Christmas.

Yes. Who won the Masters, Vance?

It was a tie in the Masters and stand by. It was a tie between Littler and Casper after 72 holes, and there is going to be a playoff Monday, we understand.

Oh. Sounds good.

One thing the world might be interested in knowing is what you do after the burn in the way of configuring switches back. We—We heard you go through the checklist. But, I guess right now, basically, you probably have all the switches back in position and you're in the mode to continue on with—Okay. What does the flight plans say? You're going to be doing cislunar navigation. So, Jack you're going to be down in the LEB. Is that correct?

That's right, Vance. Be going down there shortly.

Okay. The TV now is all but black. Looks like it must be pointing into a shadow.

What he's doing, he's trying to give you one more shot of the Moon, and right now I'm setting to maneuver pad and the optics calibration attitude.

Roger.

And what I wanted to point out, I don't know if it's apparent, but … to show the advantage of doing all the dumps just before the burn, we're looking again at the same scene over quad 1 at the Moon. And now you don't see all the sparkly frozen particles outside there any more. We've sort of run off and left them.

Roger. We—We don't see anything out there anymore in the way of particles leaving the spacecraft. We'd suggest, maybe you zoom the Moon in a little bit again so we can see the shape of it better.

Okay. That brings the Moon in. We can see the terminator at the top of the melon-shaped disk.

Okay. Now you can see a few of the spark—sparkling particles going across the screen. Those are being emitted from the thrusters. Jack's maneuvering the spacecraft now.

Okay. We can see those very poorly. Well, actually, they are coming in better now. It looks like little specks going from the upper left part of the screen across to the right, and understand those are from the thrusters.

That's affirm.

Okay, 13; Houston. Just as an item of interest, advise your speed with respect to the Earth is now 4667 feet per second.

Okay. Thanks, Vance.

Okay, Apollo 13; Houston. The Moon has been in and out of the—the—our screen here. Right now it's off at the bottom side, but we can still see the particles coming off of the spacecraft.

Okay. I am going to have to pull it out the window now, Vance. The Sun's coming up on the right side.

Roger. Understand. You —

Do you want to see any shots down in the LEB, Vance?

Say again.

Do you want to see any of the photographs or do you want the TV down in the LEB?

That's right, Jim. It would be good to see what you are doing down in the LEB or the far corner of the spacecraft where the optics are. Might be interesting to describe what you will do in the next few minutes in the way of sighting.
