NASA via ibiblio · 1969-07-31 · 251 pages · text by GLM-OCR

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

This was at the cost of probably double the amount of time that we normally would take for the bulk sample.

I want to inject a thought about spacecraft location in respect to lunar surface working location. Putting the area of the MESA in the shadow also put the cable in the shadow. The white cable, being covered with a little bit of this powdery stuff and being in the shadow, was very difficult to observe. Consideration should be given to keeping any cable or small object out in sunlight whenever possible. It leads one to think that if you're going to yaw one way or the other, it's preferable to put your working areas out into the sunlight.

We've discussed free-launch on a number of occasions and whether we wanted to yaw specifically for lighting at touchdown. There are obviously a lot of advantages, but I was very reluctant to do any fancy maneuvering on the first lunar touchdown for selected yaw for lighting considerations. I figured we'd just take what we got and we paid for that later, because we had a lot of operations in the shadow during EVA that would have been easier had we had better lighting.
