Spacelog Apollo 8

Jim is getting to know the objects.

Are you receiving the data, Houston?

Affirmative.

Okay.

Keeping you honest.

Right.

Okay, Apollo 8. We have looked at the data and it looks good and they feel like you can go back to PTC attitude anytime you are ready to. And if you can—go ahead.

What attitude do you want to use? The same one?

That's affirmative.

Thank you.

Okay, if you can reach over Bill there and get to panel 3, I believe we would like to cycle the oxygen fans. And also like to get the BIOMED switch over to CMP.

Okay.

If you have to bother Bill to do that, why, we can hold off on the cryo fans.

No, he moved. We already chased him under the seat. Okay, now you want just the oxygen fans on?

That's affirm. Turn one on for about 2 minutes and when we turn it off, then we will turn the next one on. We don't want to turn them on simultaneously though.

I know that. I mean you don't want hydrogen though?

That's affirmative. Just the oxygen.

Houston, Apollo 8.

Go ahead.

Ken, just recap a little explanation here on your maneuver PAD, something which I'm really not knowledgeable about, the way it was presented to us, you mentioned fast return P37 DELTA-V of 8750, just briefly clarify that, will you please?

Ken, can you give us a little report on how our trajectory looks and the tracking is going and things like that?

Okay, sure will. I will put a summary together here.

And the pericynthian sign.

Roger, we will get all that together for you in just a few minutes.

And we never did get the news.

You are the news.

Come off it, come off it.

Okay, the fans have been cycled 2 minutes each and they are back off.

Houston, Apollo 8 is back in the PTC attitude, reads MHPTC.

Okay, thank you. And in reference to your question about the P37 DELTA-V, 8750, that's the number that goes into the option at P37 for your minimum time return. That gives you a target for the Indian Ocean. And in this case, we are going to have to use the high-speed procedures that were worked out for you to use some minus number for the major axis.

Roger. Understand. I'm going to give that a try, Ken, in a run through. I tried it yesterday, I wasn't getting too much in the way of results. I will give it a try today.

Okay. And on the—your tracking that we have now, it still looks like the time we gave you last night for time of pericynthian is still good, 69 plus 10 and right now your flyby earth pericynthian altitude is 65.8. Looks like the midcourse number 3 is going to be something less than 1 foot-per-second. And all trajectory parameters are still holding real fine.

That's the things we like to hear. We would like to keep those holding very much.

Houston, Apollo 8.
