Gemini Capsule 

A vital stepping stone between the Mercury and Apollo programs, the Gemini capsule on display showcases NASA’s efforts to prepare for extended missions in space. Used between 1961 and 1966, the two-man Gemini spacecraft allowed astronauts to perform the first American spacewalks, practice docking with other vehicles, and test systems critical for Moon missions. Visitors will notice the roomier interior compared to Mercury, though still extremely confined by modern standards. Through interpretive displays, you can learn how Gemini missions taught astronauts to live and work in space for longer durations, control orbital mechanics manually, and conduct precise maneuvers that would later prove essential for lunar landing procedures.
