The purpose of this expedition was to test for NASA a meter called a Tissue Equivalent Proportional Counter (TEPC): testing at different altitudes (17,000 ft, 19,000 ft and 21,000 ft) would reveal how people’s bodies would be affected, including the way bodily tissues behaved, when struck by radiation, and this was important for the planning of long duration space missions.LaunchesSpace Shuttle Challenger / OV-099 | STS-51-FNational Aeronautics and Space AdministrationType: Government Abbreviation: NASA Administration: Administrator: Jim Bridenstine Founded: 1958 Launchers: Space Shuttle | SLS Spacecraft: Orion Country: USAThe 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.
