Memoranda from the Associate Administrator for Manned Space Flight describe the planned four-day mission with James McDivitt and Edward White, including a spacewalk, a rendezvous with the booster second stage and thirteen experiments. Later letters and telegrams from NASA's Manned Space Science office concern the astronaut debriefing and requests for GT-4 photography and film for scientific analysis.
