Brainerd Holmes, Director of Manned Space Flight, sought to justify a $42,638,000 increase in Project Gemini's actual 1963 budget over that previously estimated. NASA signed an almost half-billion-dollar contract with McDonnell Aircraft Corporation for the Gemini spacecraft, with a cost-plus-fixed-fee estimate of $456,650,062 ($428,780,062 plus fixed fee of $27,870,000).

Italy created its first space agency, the Istituto Nazionale per le Richerche Spaziali (IRS) (National Institute for Space Research). The caves at Lascaux were closed to the general public after fifteen years, in order to protect cave paintings dating from more than 17,000 years ago. The paintings had been rediscovered on September 12, 1940, in the caverns in southwestern France. After the complex was opened to the public in 1948, the works began to erode from carbonic acid produced by the exhalations of the visitors. The Department of Dordogne would create a replica of the paintings in another cave hall, opened as "Lascaux II" in 1983. The 1963 Pan American Games opened in São Paulo, Brazil.

Bendix Corporation completed the design and fabrication of an air lock for the Mercury spacecraft. This component was designed to collect micrometeorites during orbital flight. The air lock could accommodate a variety of experiments, such as ejecting objects into space and into reentry trajectories, and exposing objects to a space environment for observation and retrieval for later study. Because of the modular construction, the air lock could be adapted to the Gemini and Apollo spacecraft.

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.

NASA announced a number of improvements to the Mercury pressure suit for the upcoming Mercury 9 flight. These included a mechanical seal for the helmet, new gloves with an improved inner-liner and link netting between the inner and outer fabrics at the wrist, and an increased mobility torso section. 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. References
