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 through your earphone doesn't always lead you to the right conclusion and that's a little bit disconcerting. ## 6.21 S-BAND SQUELCH ## ARMSTRONG It worked very well, I thought. ## ARMSTRONG ## 6.22 DAYLIGHT IMU REALIGN AND STAR CHECK I think we already covered that by saying that with the LM on in the daylight the telescope is nearly useless and you have to rely on the sextant. Now, we never went into that mode that Apollo 10 discovered of pointing the plus X axis at the sun. We never had an occasion or need to do that. Therefore, we can't comment on it. Just staying regular PTC attitude, normal to the sunline, the telescope was just about useless. ## 6.23 VENTING BATTERIES AND WASTE ## ALDRIN When we started a battery charge, we would look at the vent and find it was usually down fairly low. I don't think there was any time when we saw it above 1.6 and as soon as we went to VENT, it would drop down to 0.2 or 0.3. I don't know how serious that is. Nobody seemed to be concerned about that. I'm sure that the ground has a readout, but they never indicated or suggested to us that we vent the batteries. ## CONFIDENTIAL
