Frederick D. Gregory - Space Flight Experience

Space Flight Experience

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, 47seconds.

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. 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.

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 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.
