Größe: ca. 25,5 x 20,5 cm Gregory was selected as an astronaut in January 1978. His technical assignments included: Astronaut Office representative at the Kennedy Space Center during initial Orbiter checkout and launch support for STS-1 and STS-2; Flight Data File Manager; lead spacecraft communicator (CAPCOM); Chief, Operational Safety, NASA Headquarters, Washington, D.C.; Chief, Astronaut Training; and a member of the Orbiter Configuration Control Board and the Space Shuttle Program Control Board. Notably, he was one of the CAPCOM during the Space Shuttle Challenger disaster. A veteran of three Shuttle missions he has logged about 456 hours in space. He served as pilot on STS-51B (April 29 to May 6, 1985), and was the spacecraft commander on STS-33 (November 22–27, 1989), and STS-44 (November 24 to December 1, 1991).[5] STS-51B Main article: STS-51B STS-51B/Spacelab-3 launched from Kennedy Space Center, Florida, on April 29, 1985, with Gregory serving as pilot. The crew aboard the Orbiter Challenger included spacecraft commander, Robert Overmyer; mission specialists, Norman Thagard, William E. Thornton, and Don Lind; and payload specialists, Taylor Wang and Lodewijk van den Berg. On this second flight of the laboratory developed by the European Space Agency (ESA), the crew conducted a broad range of scientific experiments ranging from space physics to the suitability of animal-holding facilities. The crew also deployed the Northern Utah Satellite (NUSAT). After seven days of around-the-clock scientific operations, Challenger and its laboratory cargo landed on the dry lakebed at Edwards Air Force Base, California, on May 6, 1985. Mission duration was 168 hours, 8 minutes, 47 seconds.[7] STS-33 Main article: STS-33 When STS-33 launched at night, from Kennedy Space Center, Florida, on November 22, 1989, Gregory became the first African-American to command a space flight.[8] On board the Orbiter Discovery, Gregory's crew included the pilot, John Blaha, and three mission specialists, Manley (Sonny) Carter, Story Musgrave, and Kathryn Thornton. The mission carried Department of Defense payloads and other secondary payloads. After 79 orbits of the Earth, this five-day mission concluded on November 27, 1989, with a hard surface landing on Runway 04 at Edwards AFB, California. Mission duration was 120 hours, 7 minutes, 32 seconds.[9] STS-44 Main article: STS-44 STS-44 launched at night from the Kennedy Space Center, Florida, on November 24, 1991. During 110 orbits of the Earth, the crew successfully deployed their prime payload, the Defense Support Program (DSP) satellite. They worked on a variety of secondary payloads ranging from the Military Man in Space experiment designed to evaluate the ability of a space borne observer to gather information about ground troops, equipment and facilities, and also participated in extensive studies evaluating medical countermeasures to long duration space flight. The crew aboard the Orbiter Atlantis included the pilot Tom Henricks; three mission specialists, Story Musgrave, Jim Voss, and Mario Runco Jr.; and Army payload specialist Tom Hennen. The mission concluded on December 1, 1991, with a landing at Edwards Air Force Base in California. Mission duration was 166 hours, 50 minutes, 42 seconds.[10] NASA administration During his time at NASA Gregory served at NASA Headquarters as Associate Administrator for the Office of Safety and Mission Assurance (1992–2001), and was Associate Administrator for the Office of Space Flight (2001–2002). On August 12, 2002, Mr. Gregory was sworn in as NASA Deputy Administrator.[11] In that role, he was responsible to the Administrator for providing overall leadership, planning, and policy direction for the Agency. The Deputy Administrator performs the duties and exercises the powers delegated by the Administrator, assists the Administrator in making final Agency decisions, and acts for the Administrator in his or her absence by performing all necessary functions to govern NASA operations and exercise the powers vested in the Agency by law. The Deputy Administrator articulates the Agency's vision and represents NASA to the Executive Office of the President, Congress, heads of Federal and other appropriate Government agencies, international organizations, and external organizations and communities.[12] From the departure of Sean O'Keefe on February 20, 2005, to the swearing in of Michael D. Griffin on April 14, 2005, he was the NASA Acting Administrator. He returned to the post of Deputy Administrator and on September 9, 2005, submitted his resignation. He was replaced on November 29, 2005, by Shana Dale. Quelle: Wikipedia Wichtig: Aufgrund der unsicheren Versand- und Zollbedingungen versende ich aktuell nicht in die USA.
