— 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.

-
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.
-
Michael Collins (CMP)
-
Roger. I expect you probably have about nine CAP COMMS and 11 Flight Directors with no place to plug in.

Michael Collins (CMP)

Glycol evaporator outlet temperature is 50 degrees and the comfort in here is just fine.

Apollo—Columbia, this is Houston. Your map coordinates are Papa decimal 2 and 6 decimal 3 on the LAM 2 chart. Over.
-
Bruce McCandless (CAPCOM)
-
Columbia, Columbia, this is Houston. If you read we request high gain antenna, yaw 180, pitch 0. I say again, yaw 180, pitch 0 on the high gain. Over.
-
Bruce McCandless (CAPCOM)
-
Well, what's new is I think we have some more coordinates for you on the LM location. Over.
-
Michael Collins (CMP)
-
Okay. What you are saying is, if you look at the cat's paw, then that's just about, oh—his middle finger, a little bit—one to two o'clock from his middle finger. Is that right?
-
Bruce McCandless (CAPCOM)
-
Roger. About one to two o'clock from the middle finger if you are using 12 o'clock being to the west. Over.
-
Bruce McCandless (CAPCOM)
-
Roger. Your LOS at 107 plus 23 plus 03. AOS at 108 plus 09 plus 06. The next pass for COAS tracking: your time of closest approach is 108 35 28. That's 3 miles south of track. Over.
-
Michael Collins (CMP)
-
I understand all that, but with this new information would you like me to try P22 and look for him in a different spot?
-
Michael Collins (CMP)
-
Okay. Because I was looking in the wrong place last time. AUTO optics was not pointing me at the coordinates you gave me.
-
Bruce McCandless (CAPCOM)
-
On your next pass, Columbia, rather than performing a P22 as such, we would like you to look in the vicinity of the coordinates that we gave you, which is our best analysis based on map physics and the trajectory, and we also have another set of coordinates that we would like you to search in the vicinity of. This last one being based on all interpretation of the geological features that were seen by the crew on their way down. The coordinates of this second site are Mike 0.7 and 8.0. I say again, Mike 0.7 and 8.0. I say again, Mike 0.7 and 8.0. Over.
-
Michael Collins (CMP)
-
Roger. Copy. Mike 0.7 and 8.0. The only thing is, my best tool for looking is the sextant and if I'm going to crank the sextant up, I might as well let P22 go at the same time, or don't you think so?
-
Bruce McCandless (CAPCOM)
-
Roger. If you want to go that way, crank it up and then you can drive it around and look where you want. Over.
-
Bruce McCandless (CAPCOM)
-
And if you can find the LM, then by all means, track it or make a note of where it was and we can track it on the next REV. If you are ready, we have a REFSMMAT update that we can pass up to you at this time, if you will give us P00 in ACCEPT. Over.
-
Michael Collins (CMP)
-
Okay. P00 in ACCEPT you got. And this is an updated landing site RESFMMAT. We still believe that a plane change is not required. Is that affirmative?
-
Bruce McCandless (CAPCOM)
-
Columbia, this is Houston. We are through with the uplink. It's your computer.
