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.
From the source:Release of 2026-06-12 Incident: 6/9/65, North Atlantic Ocean. This document is a preliminary transcript (Part II) derived from voice recordings of the Gemini 4 flight crew debriefing taken aboard the recovery ship, USS Wasp, on June 9, 1965. Part II of this document contains the “Visual Sightings” section of the debriefing (pages 196-224), where astronauts James McDivitt and Edward White describe their observations while aboard the spacecraft.
19 McDivitt White time . It started right after a night cycle . It seemed rather natural to me that there wasn't really something wrong, but that we actually had a cold RCS thing out there and it did need some heat . After heat was applied it did appear to go away. I decided to go ahead and set up a slow roll rate in the daytime, and I kept that roll rate in for several orbits. Whether this actually helped to get the light off or not, I don't know. We didn't get anymore lights after this time . I think there ought to be one other comment on the RCS , and that is the temperatures and the pressures stayed up pretty well except when we actuated the system. The pressures then went down further than we had expected them to go . They went down to 2400 to 2500 p~i. This was a little lower than I expected to see. I think the pressures in the RCS A and B dropped by about 100 pounds throughout the four-day period. They were slightly over 3000 pounds and they got down to slightly under 3000. The lowest temperatures I noted were in the neigh borhood of about 63 to 64 degrees. They started out at 75 degrees.
