Project Gemini (IPA: / ˈ dʒ ɛ m ɪ n i /) was the second United States human spaceflight program to fly. Conducted after the first American crewed space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966.
The Gemini Lunar Surface Rescue Spacecraft [17] was intended to fly a direct ascent mission, launched by a Saturn V. Descent stages, built from either the descent stage of the Apollo Lunar Module, or from the Apollo Service Module, would have reduced the spacecraft's velocity as it approached the Moon.
Gemini was the second phase in the United States space program's larger goal of "landing a man on the Moon and returning him safely to the Earth" before the end of the 1960s, as proposed by president John F. Kennedy. As an intermediary step, Gemini afforded its astronauts the opportunity to gain critical spaceflight experience, performing tasks ...
Gemini 3 was the first crewed mission in NASA's Project Gemini and was the first time two American astronauts flew together into space. On March 23, 1965, astronauts Gus Grissom and John Young flew three low Earth orbits in their spacecraft, which they nicknamed Molly Brown .
Gemini 3 launched at 9:24 a.m. from LC-19 and entered in a 122 × 182 km (76 × 113 mi) elliptical orbit. [7]: 223 [8] Twenty minutes into flight, Young recognized multiple anomalous system readings and determined that there might be issues with the instrument power supply. He switched from the primary power supply to the backup, which solved ...
Gemini 11 (officially Gemini XI) [2] was the ninth crewed spaceflight mission of NASA's Project Gemini, which flew from September 12 to 15, 1966.It was the 17th crewed American flight and the 25th spaceflight to that time (includes X-15 flights over 100 kilometers (62 mi; 54 nmi)).
A Titan II launch vehicle lifts Gemini 4 into orbit, June 3, 1965. Launched from LC-19 at Cape Kennedy Air Force Station, Florida, Gemini 4 was the first flight to be controlled by the new Mission Control Center at the Manned Spacecraft Center in Houston, Texas, which had to conduct three-shift operations due to the flight's long duration.

The Gemini spacecraft was launched into an 86-by-147-nautical-mile (159 by 272 km) orbit by a modified Titan II on March 16, 1966 (coincidentally the 40th anniversary of the launch of the world's first liquid-fueled rocket by Dr. Robert H. Goddard), at 10:41:02 a.m. EST. Gemini 8's launch was nominal and no significant anomalies occurred with ...
