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.

## CONFIDENTIAL

optics pointing down the Z-axis and then you could be free to pass that test and still have the spacecraft pointing 180 degrees out from where you want it to be. It will still pass that test, so in our view that wasn't particularly good. You were really just checking your alignment of the platform, which is really not what you're trying to do. You're trying to check that the spacecraft is pointed the way you want it pointed so that was the reason for our request for additional star checks.

6.17 ADEQUACY OF CSM/MSFN COMM PERFORMANCE AND PROCEDURES FOR COAST DURING AGA REFLECTIVITY TEST

NS Okay. Adequacy of all this stuff for the AGA reflectivity test. I understand we didn't have that and we cancelled that.

## COLLINS

I thought in general the onboard color television system was well designed and was easy to operate. Buzz, you got anything to say about that?

## ALDRIN

It was quite easy to hook up and put together. We ended up putting the two together making use of tape instead of the Velcro that was on there, to get the monitor right close to the camera. I think initially we were a little
