Bowen has been on three spaceflights, all of which were Space Shuttle missions to the International Space Station. His first mission, STS-126, took place in November 2008, and his second was STS-132 in May 2010. In March 2011, Bowen completed his third spaceflight as a Mission Specialist on STS-133, which was Space Shuttle Discovery’s final planned flight. Having flown on both STS-132 and STS-133, Bowen became the first and only astronaut to fly on consecutive shuttle missions. Originally Tim Kopra was scheduled to fly on STS-133, but Kopra had a bicycle injury shortly before the mission, and so he was replaced by Bowen.LaunchesSpace Shuttle Endeavour / OV-105 | STS-126Space Shuttle Atlantis / OV-104 | STS-132Space Shuttle Discovery / OV-103 | STS-133National 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.
