When did Gemini 3 make its first manned space flight?

1965 On March 23rd, Gemini 3 made its first manned space flight. Astronauts Virgil I Gleason and John W Young completed the flight. During the flight, the astronauts started the propeller to change the orbit shape and implemented a slight inclination change. Two months later, astronauts James A. McDivitt and Edward H. White flew into space on Gemini 4 for five days. In the third orbital flight, White achieved the first spacewalk in the United States. When leaving the cabin, it is connected by pipes and cables, and the space maneuver is realized by small hand-held rockets.

An important task of Gemini project is to realize orbital rendezvous and docking. On February 4th, 1965, 15, 12, 15, "Gemini 7" and "Gemini 6" respectively went into space and met in space, flying continuously for more than 7 hours, with a distance of only 40 meters, and the latest flight was only 0.3 meters. Later, the missions of Gemini 8 and Gemini 9 were to dock with the Aquinas rocket, but they didn't come true.
