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 television, and the experiments, they looked as though they were right outside the window. In fact, on the surface, we had moved them a reasonable distance away. So I think distance judgment is not too good on first setting down. The tendency is to think that things are a good bit closer than they actually are. This says they are probably a good bit larger than what we might have initially estimated. ## ARMSTRONG ## 10.10 COLORS AND SHADING OF LUNAR SURFACE FEATURES Probably the most surprising thing to me, even though I guess we suspected a certain amount of this, was the light and color observations of the surface. The down-Sun area was extremely bright. It appeared to be a light tan in color, and you could see into the washout region reasonably well. Detail was obscured somewhat by the washout, but not badly. As you proceeded back toward cross-Sun, brightness diminished, and the color started to fade, and it began to be more gray. As we looked back as far as we could from the LM windows, the color on the surface was actually a darker gray. I'd say not completely without color, but most of the tan # CONFIDENTIAL
