Gemini 3
The first two-man American space crew lifts off in the first manned flight of NASA’s Gemini program. With a larger, more maneuverable spacecraft designed for longer stays in space, Gemini is intended to be a stepping stone on the path to the first lunar landing, allowing astronauts to practice rendezvous, docking, and orbital changes. Aboard the Gemini capsule are Mercury veteran Gus Grissom and rookie John Young; the capsule is unofficially nicknamed “Molly Brown” (a reference to Grissom’s sunken Mercury capsule). The flight lasts barely five hours and includes the first-ever orbital attitude changed made by a manned spacecraft.
