Lucid, Shannon Matilda Wells (1943–)
Shannon Lucid is a retired American astronaut and the first woman to go into space more than twice. Lucid received a B.S. in chemistry (1963), and M.S. (1970) and Ph.D. (1973) in biochemistry, from the University of Oklahoma. Selected by NASA in January 1978, she became an astronaut in August 1979 and is qualified for assignment as a mission specialist on Space Shuttle flight crews. A veteran of five space missions, Lucid has logged 223 days in space – the most by any woman – including flights aboard STS-51G (1985), STS-34 (1989), STS-43 (1991), STS-58 (1993), and Mir (launching March 22, 1996, aboard STS-76 and returning September 26, 1996 aboard STS-79).
