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 BS in chemistry (1963), and MS (1970) and PhD (1973) in biochemistry, from the University of Oklahoma. Selected by NASA in Jan 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 22 March 1996, aboard STS-76 and returning 26 September 1996 aboard STS-79).
