Spacelog Apollo 8

Roger. We'd like high bit rate. We have dumped your DSE, and we'd like to stick with high bit rate for a while.

Roger.

Well, we're just about over Maskelyne B (Marsh Of Sleep) now, and our target is just directly below us.

Apollo 8, this is Houston. If you want the recorder now, it's yours.

Roger. Thank you.

Apollo 8, Houston. MSFN tracking is comparing very well with your onboard NAV.

Roger. We concur.

Are you sure you didn't turn off the transmitters at that time?

Honest Injun, we didn't.

While these other guys are looking at the moon, I want to make sure we have a good SPS. How about giving me that report when you can?

Sure will, Frank.

We want a GO for every REV please; otherwise, we'll burn in TEI 1 at your direction.

Apollo 8, this is Houston. Are you eating?

Say again.

Apollo 8, this is Houston. Are you eating dinner?

Negative. We'll have breakfast in a little while here.

Roger.

Apollo 8, this is Houston. When you go into the dark in about 7 or 8 minutes, I have some words for you on the filters for the wide-angle lens, for your TV camera. Over.

We are in the dark now.

Roger. Let me know when you are ready to copy.

Apollo 8, Houston. Any words on earthshine? Over.

Earthshine is about as expected, Houston. Not as much detail, of course, as in the sunlight, but you can see the large craters quite distinctly, and you can see the albedo contacts quite distinctly. And, also, the—there's a good three-dimensional view of the rims of the larger craters.

Roger, Bill.

I think our high-speed film will be able to pick some of this stuff up quite well.

Go ahead with your information on the filter, Houston.

Apollo 8, Houston. Roger. We recommend you use a wide-angle lens on this particular TV run. You can use a telephoto lens with the same setup as yesterday's TV show. However, we recommend a wide-angle lens. Step number 1, tape the single red filter to the red filter on the red/blue 0 filter holder; do it so that the filter slide still functions. Over.

Go ahead.

Roger. Step number 2, attach the filter holder to the lens with the tape on the top and bottom; do this with the slide forward. Over.

Go ahead.

Roger. Then at the end of your second REV TV pass, or on request from here, we would like you to remove that red filter from the holder and transmit briefly with it that way, then slide it over the blue side for your final transmission. Over.

We got you.

Okay, Frank.

Houston, Apollo 8. Standing by to record TEI 1 and TEI 2.

Apollo 8, this is Houston. Your TEI 1 and TEI 2 PAD's you received last pass are still good. Using these PAD's, your next midcourse will be less than 20 feet per second. Over.

Roger. Understand.

Apollo 8, Houston. We have all the SPS experts looking at your data now. The preliminary look is very good, and we will give you some final words later.

Roger. We could feel the chug when we threw in BANK B, not a chug, but we could feel additional thrust.

Roger. Copy.

Houston, be advised on this red/blue filter technique on the TV. You cannot slide the two filters out of the way with them taped onto the TV camera; so I suggest we do red, blue, and then take them off.

Roger. We concur, but make sure the little red filter is taped over the big one. Over.

Alright, you don't want the red fil—you want the blue by itself. Is that correct?

That's affirmative, Bill.

Bill, we'd like you to use the double red filter for the first transmission. Over.

Roger. It worked.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.
