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.
- CapCom
-
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.
- Buzz Aldrin (LMP)
-
All right. We'll plan it that way. Over.

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.

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. 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.
- CapCom
-
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.
- CapCom
-
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.
- Michael Collins (CMP)
-
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?
- CapCom
-
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.
- Michael Collins (CMP)
-
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.
- CapCom
-
Roger, Columbia. Did you shift into manual control, or did the problem resolve itself under AUTO control? Over.
- Michael Collins (CMP)
-
I did cycle out of AUTO into—I did cycle out of AUTO into MANUAL, back into AUTO.
- CapCom
-
Tranquility, this is Houston. We need a second set of PRD readings so that we may establish a rate. Over.
- Michael Collins (CMP)
-
Houston, Columbia. I'm coming up on my time for the first pass when I may —

— 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.
- CapCom
-
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.
- CapCom
-
Columbia, Houston. Another possibility is the southern rim of the southern of the two old looking craters. Over.
- Michael Collins (CMP)
-
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.
- CapCom
-
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.
- Michael Collins (CMP)
-
Its going past now, Bruce, but I scanned that area that you are talking about very closely, and no, I did not see anything.
- Bruce McCandless (CAPCOM)
-
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.
- Michael Collins (CMP)
-
The other one is located at 7—The other one is located at 7.2, two thirds of the way from Mike to Nan.
- Bruce McCandless (CAPCOM)
-
Roger. We believe you were looking a little too far to the west and south. Over.
- Michael Collins (CMP)
-
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?
- Bruce McCandless (CAPCOM)
-
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.
- Michael Collins (CMP)
-
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.
- Bruce McCandless (CAPCOM)
-
Tranquility Base, this is Houston. Can you give us some idea of where you are in the surface checklist at the present time? Over.
- Michael Collins (CMP)
-
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?
- Bruce McCandless (CAPCOM)
-
Roger. Reading you loud with background noise. Understand that's OMNI Delta or OMNI Bravo? Over.
- Michael Collins (CMP)
-
OMNI Delta and you were cut out. I never got your coordinates on estimated LM position. Over.
- Bruce McCandless (CAPCOM)
-
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.
- Michael Collins (CMP)
-
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.
- Michael Collins (CMP)
-
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?
- Bruce McCandless (CAPCOM)
-
Roger. There's not much going on at the present time, Columbia. I'll see what I can do about the relay.
- Bruce McCandless (CAPCOM)
-
Columbia, this is Houston. Are you aware that Eagle plans the EVA about 4 hours early? Over.
- Bruce McCandless (CAPCOM)
-
Roger. Somewhere around 108 hours. We'll have an update for you on that a little later.
- Michael Collins (CMP)
-
Okay. I haven't heard a word from those guys, and I thought I'd be hearing them through your S band relay.
- Bruce McCandless (CAPCOM)
-
Roger. They're on about page Surface 27 in the checklist, proceeding in good time.
