Preliminary Gemini 4 Crew Debriefing, Part II, 1965

This is a preliminary transcript of Part II of the Gemini 4 (GT-4) flight crew debriefing, prepared by NASA's Spacecraft Operations Branch, Flight Crew Support Division, and dated June 18, 1965. The debriefing began aboard the recovery ship USS Wasp and ended at the Manned Spacecraft Center. In it, astronauts McDivitt and White discuss how the spacecraft systems performed, including the platform, OAMS, RCS and control modes. They also cover operational checks, visual sightings, experiments, mission planning and training, and give recommendations for future crews.

White Okay, t he systems monitoring. I thought it was
satisfactory . We went through and monitored the
systems every time for the GO/NO GO checks, and
quit e a few times along the line in addition to
this. So I thought the method of monitoring was
satisfactory. I don't believe we really had any
way of monitoring the electrical power remaining.
McDivitt Yes, that ' s a draw back, and we all know it, I
guess .
White Right . That ' s an unsatisfactory conditionmd
I don ' t know what we're going to do about it.
I think it's too much of a job to try to think
that you ' re going to sit in there and calculate
all the things you have on,and try to keep an
onboard plot of what electrical power you have
remaining .
McDivitt Yes , I think this is a ground function . I don't
think that we can realistically do it onboard the
spacecraft .
White I don't believe we got any indication of how our
electrical power was going from the ground,except
