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.

or how well you measured that, because it's relative to how well the gravity was measured.

We had an update concerning the position to leave the radar for ascent. We were instructed by the ground not to turn the radar on during ascent and to leave it in SLEW.

I think we left the circuit breakers out. This was to keep from overloading the computer, in a similar way to what had happened during the previous day during descent. I think that's unfortunate that we do have to deprive ourselves of one additional check for insertion confirmation. There was one more venting of the descent tanks at insert lift-off minus 30 minutes. I had the radar in SLEW and the circuit breakers off.

I'm quite sure they were off.

Well, I didn't want us to use the tape meter in PGNS. Now that would have given us altitude and altitude rate out of the PGNS, right? So they didn't want to burden down the PGNS with doing that. Here I have on the circuit breaker card, leaving both radar circuit breakers open.
