Spacelog Apollo 11

Roger, Columbia. You're sounding much better now.

Columbia, Houston. Request P00 in ACCEPT, and we'll uplink another state vector. Over.

Roger. Going P00 in ACCEPT.

Columbia, Houston. Suggest you put BATT A on your BATT relay bus. Over.

Okay.

Columbia, Houston. We're through with your computer. You can go to BLOCK.

Roger. BLOCK.

Tranquility Base, Houston. Over.

Go ahead, Houston. Tranquility Base.

Tranquility Base, Houston. We've reviewed the checklist, and about the only change in order to advance the EVA that we've found is that you'll want to delay your lithium hydroxide change until after the EVA rather than before. Over.

Roger. We'd just as soon make a change and jettison the old one. Over.

Tranquility Base, Houston. We would like to delay that LOIO—LiOH change until after the EVA. There is a possibility you could jettison the canister when you jettison your PLSS. Over.

All right. We'll plan it that way. Over.

Roger, Tranquility.

Columbia, Houston. Over.

Houston, Columbia.

Columbia, Houston. We show your EVAP OUT temperature running low. Request you go to manual temperature control and bring it up. You can check the procedures in ECS MAL 17. Over.

Roger, Houston.

Columbia, Houston. I have a P22 update for you.

Columbia. Go ahead.

Columbia, Houston. Your P22 AUTO—AUTO optics landmark ID on LM. T1, 106 plus 30 plus 31; T2, 106 plus 35 plus 41, 2 nautical miles south. Your TCA, 106 plus 37 plus 16. Shaft angle 357.9 and trunnion angle 44.3. Over.

Roger. Thank you.

Columbia, Houston. We have your LOS in 3 minutes. AOS will be 106 plus 11. Over.

Houston, Tranquility. Over.

Tranquility, Houston. Go ahead.

Roger. This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. Over.

That's about ready to fall off.

Tranquility Base, Houston. We'd like some estimate of how far along you are with your eating and when you may be ready to start you EVA PREP. Over.

I think that we'll be ready to start EVA PREP in about a half an hour or so.

Houston, Columbia. How do you read?

Columbia, Columbia. This is Houston.

Houston, this is Tranquility Base. We are beginning our EVA PREP.

Tranquility Base, this is Houston, Roger. Copy. You're beginning EVA PREP. Break. Break. Columbia, Columbia, this is Houston. Reading you loud and clear. Over.

You're loud and clear. The waste water dump is down to 10 percent. I have a question on the P22. Do you want me to do another P22, or is all that information just for my own use in tracking the LM for photographic purposes?

Columbia, this is Houston. We request that you perform another P22. We'd like you to let the AUTO optics take care of the tracking and devote your energies to trying to pick out the LM on the lunar surface. If you can find the LM, of course. We're looking for marks on it; but tracking of geographical features doesn't do us all that much good. Over.

Okay. Fine. I'll do it. And on the ECS system, the—Whatever the problem was, it seems to have gone away without any changing of J52 sensors or anything like that. My glycol evaporator outlet TEMP is up above 50 now, and it's quite comfortable in the cockpit; so we'll talk more about that one later.

Roger, Columbia. Did you shift into manual control, or did the problem resolve itself under AUTO control? Over.

The problem went away under AUTO.

Roger. That's the best type. Out.

I did cycle out of AUTO into—I did cycle out of AUTO into MANUAL, back into AUTO.

Tranquility Base, Tranquility Base, this is Houston. Over.

Go ahead, Houston.

Tranquility, this is Houston. We need a second set of PRD readings so that we may establish a rate. Over.

Houston, Columbia. I'm coming up on my time for the first pass when I may —

Now while we've got time, you can.

— be able to see the LM. Do you have any topographical cue that might help me out here? AUTO optics is tracking between two craters. One of them, as the LM sees it, would be long at 11 o'clock. The other would be short and behind him at 5 o'clock. They're great big old craters—depressions.

Stand by.

Columbia, this is Houston. The best we can do on topo features is to advise you to look to the west of the irregularly shaped crater, and then work on down to the southwest of it. Over.

Columbia, Houston. Another possibility is the southern rim of the southern of the two old looking craters. Over.

Roger, Houston. Columbia … I kept my eyes glued to the sextant that time hoping I'd get a flash of reflected light off the LM, but I wasn't able to see any of my scan areas that you suggested.

Roger. On that southern of the old craters, there's a small bright crater on the southern rim. One plot would put him slightly to the west of that small bright crater, about 500 to 1000 feet. Do you see anything down there? Over.

Its going past now, Bruce, but I scanned that area that you are talking about very closely, and no, I did not see anything.

Roger. Out.

Columbia, this is Houston. Over.

Go ahead.

Columbia, this is Houston. On your LAM 2 map, we'd like to confirm the topographical area in which you were looking on this last period of sightings. As we understand you, you were looking in the vicinity of Papa 7 to November 8. Is that correct? Over.

Stand by one.

Roger.

Houston, Columbia.

Go ahead, Columbia.

One of the craters I was talking about is located exactly at Mike 6.7.

Roger. We found that one.

The other one is located at 7—The other one is located at 7.2, two thirds of the way from Mike to Nan.

Roger. We believe you were looking a little too far to the west and south. Over.

Roger. Understand. I was looking where auto optics was tracking, on the average, and understand that it should have been more to the north and more to the west; actually a tiny bit outside the circle, huh?

More to the north and a little more to the east. The feature that I was describing to you, the small bright crater on the rim of the large, fairly old crater, would be about Mike 0.8 and 8.2. Over.

Well, just give me your best estimate as to his location and his coordinate system, and I'll plot it on my map and go from there.

Tranquility Base, this is Houston. Can you give us some idea of where you are in the surface checklist at the present time? Over.

Okay. We're at the top of page 27.

Roger. Out

Houston, Columbia. Over.

Go ahead, Columbia.

Roger. I finally got you back on OMNI D. I've been unsuccessfully trying to get you on the high gain, and I've gone COMMAND RESET to PROCESS. How do you read me now?

Roger. Reading you loud with background noise. Understand that's OMNI Delta or OMNI Bravo? Over.

OMNI Delta and you were cut out. I never got your coordinates on estimated LM position. Over.

Columbia, this is Houston. Estimated LM position is latitude plus 0.799, longitude over 2 plus 11.730. On your chart we would place it—Stand by on the charts and readback on the latitude and longitude.

Yes. The latitude and longitude over 2, 799 and 11730 are the ones that I been using in P22. But what I'm interested in is—is grid coordinates on that map we're using.

Roger. We'll have them for you in a second.

Thank you.

Houston, Columbia. Could you enable the S band relay at least one way from Eagle to Columbia so I can hear what's going on?

Roger. There's not much going on at the present time, Columbia. I'll see what I can do about the relay.

Columbia, this is Houston. Are you aware that Eagle plans the EVA about 4 hours early? Over.

Affirmative. When's hatch open time in GET estimated?

Roger. Somewhere around 108 hours. We'll have an update for you on that a little later.

Okay. I haven't heard a word from those guys, and I thought I'd be hearing them through your S band relay.

Roger. They're on about page Surface 27 in the checklist, proceeding in good time.
