1965.11.29 - Gilruth requests concurrence of NASA Headquarters for doffing the G5C pressure suits during orbital flight in Gemini VII.


Director Robert R. Gilruth, Manned Spacecraft Center, requested the concurrence of NASA Headquarters in plans for doffing the G5C pressure suits during orbital flight in Gemini VII. Both astronauts wanted to remove their suits after the second sleep period and don them only for transient dynamic conditions, specifically rendezvous and reentry.

Primary concern was preventing the degradation of crew performance by maintaining crew comfort during the long-duration mission. Gemini Program Office had participated in the G5C suit program and certified the suit for intravehicular manned flight in the Gemini spacecraft on November 19. When Gemini VII was launched on December 4, the mission plan required one astronaut to be suited at all times, but on December 12 NASA Headquarters authorized both crew members to have their suits off at the same time.
