Thornton, who became an astronaut in 1985, most recently was payload commander in charge of microgravity experiments aboard the Space Shuttle Columbia last October. She was part of a seven-person crew that worked on a variety of experiments yielding new information in biotechnology, fluid physics and materials science. She helped repair the Hubble Space Telescope by outfitting it with new solar energy panels during a previous assignment aboard the Space Shuttle Endeavour in December 1993. A veteran space-walker, Thornton has logged more than 590 hours in space. A graduate of Auburn University, she earned two advanced degrees in physics from U.Va.: a master's degree in 1977 and a doctorate in 1979. Among Thornton's many honors are U.Va.'s Women's Center's 1994 Distinguished Alumna Award and a 1994 resolution commending her service that was passed by the Virginia state legislature. She is married to Stephen T. Thornton, a U.Va. physics professor. ### March 18, 1996
