Gemini SC6 Capability: Human transportation to low Earth orbit. Maiden Flight: 1964-04-08 Flight Life: Between a few hours and multiple days (14 day is the maximum achieved). Crew Capacity: 2 Gemini SC6 is the Gemini capsule used for the Gemini 6 mission launched on December 15, 1965 and crewed by astronauts Walter M. Schirra, Jr. (command pilot) and Thomas P. Stafford (pilot). History The Gemini crew capsule (referred to as the Reentry Module) was essentially an enlarged version of the Mercury capsule. Unlike Mercury, the retrorockets, electrical power, propulsion systems, oxygen, and water were located in a detachable Adapter Module behind the Reentry Module. A major design improvement in Gemini was to locate all internal spacecraft systems in modular components, which could be independently tested and replaced when necessary, without removing or disturbing other already tested components. The spacecraft was 18 feet 5 inches (5.61 m) long and 10 feet (3.0 m) wide, with a launch weight varying from 7,100 to 8,350 pounds (3,220 to 3,790 kg). Agency National Aeronautics and Space Administration Type: Government The National Aeronautics and Space Administration is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA have many launch facilities but most are inactive. The most commonly used pad will be LC-39B at Kennedy Space Center in Florida.
