Collection Item Summary:
The Mercury capsule #10 was one of 20 Mercury spacecraft built, but was never flown. It was used as an unmanned flight qualification vehicle by the manufacturer, McDonnell Aircraft Corporation of St. Louis, in an orbital test series in the vacuum chamber. It was later used for testing by the NASA Manned Spacecraft Center (now Johnson Space Center) in Houston.
In 1967, NASA transferred the spacecraft to the Smithsonian Institution. Around 1980, the Kansas Cosmosphere restored the spacecraft to its orbital configuration.
