Spacelog Apollo 8

Very good; we'll be there.

Yes, I'm sure you will.

I don't think those waves are too high. We're going to have to sit in this heap for about 45 minutes.

Okay. We'll put in a kit for some small waves.

Apollo 8, Houston.

Go ahead.

Okay. Why don't you drive it back over to the PTC attitude and put it back in ATTITUDE HOLD for the roll, and we're going back in and review the DTO requirement. You have about the same results, it looks like, on a cursory analysis all three times. So we're going to take another look and see if there is any reason to do it again. If so, we'll call you. You can go ahead and put it back in ATTITUDE HOLD now.

Houston, Apollo 8. Radio check.

Loud and clear, Apollo 8.

Okay, Ken. Thank you.

Roger. It is taking us a little longer to go through and rehash all of the entry checklist than I though, and we are just about to wrap it up now.

No problem. Just watch my gimbal angles for me, and give me a call if they get too close.

Apollo 8, Houston.

Go ahead.

We would like to look at a couple more DELTA-V tests on the EMS, and the general consensus is that we don't think there is any particular problem. We'd like to go ahead and take a look at what you get by running four or five more DELTA-V tests. And prior to that, we'd like to run one of these null bias tests; and since we don't have any way of monitoring any of this stuff on the downlink, I'd like to have you tell us each step when you turn the switch and different orders and things like that.

Okay.

Alright. I'll run a test.

Okay. The first thing we want is this null bias, 100 seconds.

You stand by, and I'll do a null bias for 100 seconds. Do you want me to put DELTA-V in AUTOMATIC and let it alone for 100 seconds?

That is affirmed.

Going to DELTA-V; going to AUTO -

Now.

Roger.

Went to one-tenth and back to zero.

Understand; plus one-tenth and back to zero.

One-tenth, now it's a minus one-tenth and back to zero; no, it's not zero yet; wait a minute.

Now it's up some, minus 4; 0.4, that is.

Roger.

Minus 25.

Roger.

Minus 26.

Minus 0.7, and there is 100 seconds; minus 0.7 at 100 seconds.

Roger.

Now what do you want?

Apollo 8, Houston.

You back, Ken?

Apollo 8, this is Houston.

Roger. Read you.
