Spacelog Apollo 8

Go ahead, Houston.

Okay, Apollo 8. We would like to update your LM state vector, CSM state vector, and target point. If it is convenient now, why, we will go ahead and do that if you will go to P00 and ACCEPT.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay. The loads are in and verified, and the computer is yours.

Okay.

You can take it back to BLOCK, and for Bill's information, latest guess from the main bus post-SEP voltage to 27.5

Guess! You mean the EECOM's are guessing?

At least, they are honest for a change.

That is more than you can say for the computers.

Apollo 8, Houston.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay, 8. We have an entry PAD for you.

Good. Just a minute.

Ready to copy, Houston.

Houston, Apollo 8. Entry PAD as follows: mid-Pacific, 357 152 359 146:29:30 268 plus 0813 minus 16503 065 36221 645 12122 36301 146:46:14 0028, next block not applicable, 400 0212 0025 0334 0814 16059 312, Zeta Persei, up 165, right 35 up, use nonexit EMS pattern, backup alignment; Sirius, Rigel, roll 308, pitch 209, yaw 357, and we won't need P65.

Okay, Apollo 8. I would like to verify sextant star shaft 0590, and the boresight star.

Roger.

The last one is right 34. Over.

Roger. Boresight star is right 34. And I have the sextant shaft; that's 0590.

Apollo 8, Houston.

Apollo 8, Apollo 8, Houston.

Go ahead, Houston.

Okay, Apollo 8. Can you tell us if you've done anything with your potable water? We've noticed our readout has gone from 100 percent down to 56 in the last couple of minutes.

We're reading about 50 percent right now.

Roger. That correlates with what we see. Have you done anything to change configuration? Over.

Yes, we noticed the venting here, too, Houston.

Jim, did you mean you could visually see it?

Yes, we're—oh, stand by, Ken. Bill just dumped urine, so that might have been urine we were seeing.

Bill just shut the potable inlet, Ken.

Houston, Apollo 8.

Go ahead, 8.

Apollo 8, Apollo 8, go ahead.

Roger, Houston. We're still showing about 52 percent, and we had our switch on waste so we don't know whether it dropped from a higher value or not. Has yours been stabilized now?

That's affirmative; ours has stabilized now. It was reading full just a few minutes ago.

Roger. I don't think—we can't account for any sudden drop in water.

Okay. We looked in the malfunction procedures, and number 28 doesn't reveal anything very startling.

Okay. I'm looking at malfunction 28, and it takes you to box 6, but I don't really think that's the problem because the waste tank quantity hasn't changed any. Over.

Okay. I concur. We're watching the same thing.

Look, we don't care about the potable tank, but we do about the waste tank, so just in case there is a problem somewhere, I'm going to shut the potable tank off and leave the waste tank inlet valve open. How does that sound to you?

Stand by. Okay, 8. We concur.
