* NASA Headquarters approved rescheduling of the Gemini flight program due to late delivery of the spacecraft systems. In the revised program, Gemini 1 was still set for December 1963 as an uncrewed mission but would be orbital rather than suborbital to flight-qualify the Titan II GLV subsystems and demonstrate the compatibility of the launch vehicle and spacecraft. Gemini 2, originally a crewed orbital flight, was set for July 1964 as an uncrewed suborbital flight to test spacecraft reentry under maximum heating-rate reentry conditions. Gemini 3, formerly planned as an orbital rendezvous mission, became the first crewed flight, a short-duration (probably three-orbit) systems evaluation flight scheduled for October 1964. Subsequent flights were to follow at three-month intervals, ending in January 1967. Gemini 4 would be a seven-day mission using a rendezvous pod. Gemini 6 was to be a 14-day long-duration mission with rendezvous with the Agena D target vehicle.

The boots were integrated with the suit to provide additional comfort for the longer mission, to reduce weight, and to provide an easier and shorter donning time. Another change relocated the life vest from the center of the chest to a pocket on the lower left leg. This modification removed the bulkiness from the front of the suit and provided for more comfort during the flight.
* After U.S. Secretary of Defense Robert McNamara implied that the U.S. Air Force would take over Project Gemini, NASA Associate Administrator Robert C. Seamans, Jr. stressed that although the U.S. Department of Defense had a vital role in Gemini management and operations, NASA had the final and overall responsibility for program success.
