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 Aristarchus. There was as much earthshine on the dark side of the terminator as there was later on, but your eyes could just not adapt to it, and it was just pitch black. After a short while you would be able to pick up fairly reasonable lighting coming from the Earth. I don't know what you would relate that to, or if you'd say that's at all adequate for any landing operations. I doubt that. It certainly did enable you to make observations. I think that adequately states it. We didn't do an extensive amount of observing in earthshine. ARMSTRONG I thought it was about 5 to 10 minutes past the terminator before I was really observing things in earthshine very well. ALDRIN I think earthshine is four or five times as bright as moonshine on the Earth. ARMSTRONG I don't remember making the comparison. It was done on previous flights. Some of the people on previous flights thought it might be conceivable to make landings into earthshine. I don't guess I would be willing to go that far yet. It looked like the amount of detail that you could pick up, at least from orbital altitude, wasn't consistent with what you really need in order to do a descent. ## CONFIDENTIAL
