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 with any of the brighter areas we saw in the sunlit portions say on the back side; it didn't look like it was the same thing at all. Not having anything to compare it with in the way of earthshine illumination, we really couldn't tell much. ARMSTRONG We could say the effect was there, and it was a very pronounced effect. It's a more obvious effect than looking at the Earth's zodiacal light. It's a more pronounced effect than zodiacal light which is also observed easily with the eye. Our post-LOI-2 P52 option 3 was a good one with an extremely low torquing angle (torqued at 81.05). After this, we prepared the tunnel for LM ingress. ALDRIN Let's go back to the first time we went into darkness on the front side, in higher orbit before LOI-2. This was before we got to the region of the landing site. It wasn't illuminated at that point. I guess it's a question of your eyes being light-adapted to the lighter things that you are looking at that are in sunlight. The contrast when going into the terminator was very vivid. There was just nothing to be seen, yet you would wait a short while and then you'd pick up earthshine, and you could see quite well. As soon as the sunlit portion of the Moon disappeared from your eyes, you could get dark-adapted. Then we could start looking at things like ## CONFIDENTIAL
