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

I think that they retained their present position pretty well. When I decided that I wanted to change the slope of the package one way or another, I found that I had difficulty in getting it to sink down a little more on one side. Even by scraping it back and forth, I couldn't seem to lower one edge as much as I would have liked to have.

ARMSTRONG There was no difficulty in the laser reflector installation. It worked as we expected.

10. 41 DOCUMENTED SAMPLE COLLECTION

## ALDRIN

Let's discuss the documented sample. We were obviously running out of time at the end of the EASEP deployment. We had limited time to conduct the documented sample. A figure of 10 minutes was used. I thought we might actually progress in a formal excursion and get something started anyway.

As the box was opened, we got the report that they wanted two core tubes and it looked like that was probably going to take most of the time. While I proceeded to that — because that's essentially a one-man operation — Neil went around the backside of the LM and picked up what rocks he could identify, getting as wide a variety as possible. In unpacking the box with the core tubes, I was quite careful to try to identify where the caps were. In some simulations, we had misplaced them or they had dropped to the surface.
