Hans Wilhelm Schlegel (Überlingen, 3 August 1951) is a German physicist, an ESA astronaut, and a veteran of two NASA Space Shuttle missions. From 1995 to 1997, he trained as the backup crew member for the German-Russian Mir'97 mission, and afterwards received additional training in Russia to become qualified as a second board engineer for the Mir space station. In 1998, he became a member of the European Astronaut Corps. Schlegel was a Mission Specialist on the STS-122 Space Shuttle mission. The mission was charged with the responsibility of putting the Columbus laboratory in orbit, in addition to its connection to the International Space Station.
STS-55 (Space Transportation System 55), or D-2 was the 55th overall flight of the US Space Shuttle and the 14th flight of Shuttle Columbia. This flight was a multinational Spacelab flight involving 88 experiments from eleven different nations. The experiments ranged from biology sciences to simple earth observations.Low Earth Orbit
STS-122 was a NASA Space Shuttle mission to the International Space Station (ISS), flown by the Space Shuttle Atlantis. STS-122 marked the 24th shuttle mission to the ISS, and the 121st space shuttle flight overall. The mission was also referred to as ISS-1E by the ISS program. The primary objective of STS-122 was to deliver the European Columbus science laboratory, built by the European Space Agency (ESA), to the station. It also returned Expedition 16 Flight Engineer Daniel M. Tani to Earth. Tani was replaced on Expedition 16 by Léopold Eyharts, a French Flight Engineer representing ESA. After Atlantis' landing, the orbiter was prepared for STS-125, the final servicing mission for the Hubble Space Telescope.Low Earth Orbit
The European Space Agency is an intergovernmental organisation of 22 member states. Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,000 employees. ESA's space flight programme includes human spaceflight (mainly through participation in the International Space Station program); the launch and operation of unmanned exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana.
