This is Volume 1 of NASA's Apollo 11 Technical Crew Debriefing, dated July 31, 1969. The Mission Operations Branch of the Flight Crew Support Division at the Manned Spacecraft Center in Houston prepared it, and it was originally classified Confidential. In it Armstrong, Aldrin and Collins go phase by phase through suiting, launch, powered flight, Earth orbit and lunar surface activities. They comment on suit fit, vibration, checklists, lunar dust, footing and poor sleeping conditions in the lunar module. A section titled Visual Sightings appears in the table of contents.

## CONFIDENTIAL ARMSTRONG (CONT'D) you're getting a lot of local reflection from earthshine. That certainly — ALDRIN You talking about once when we were in lunar orbit? ARMSTRONG Yes. I would certainly agree, particularly with the highly illuminated parts of the inside of the crater wall. I think it was also true that the area around Aristarchus, that is in the plains, was also more illuminated. ALDRIN It wasn't just the crater, it was the whole general area. ARMSTRONG It's not necessarily obvious that this also would happen to agree with the zero phase point of earthshine. COLLINS It could. We had nothing to compare it with. ALDRIN This was not in sunlight; it was in earthshine. That wouldn't have been zero ... ARMSTRONG Offhand, it doesn't agree with anything I can think of, and it seemed to extend for quite a distance around that area. Although I called that a fluorescence, it's probably not a very good term. It certainly did not have any colors that I could associate it with. There was just a higher local illumination level over the surface at that point. ALDRIN It was a brighter area than anything else we could see in either direction. I don't know if you could compare that ## CONFIDENTIAL
