The program, Space Flight: A Human Perspective, begins at 7 p.m. at the Maxwell Theatre, 2500 Walton Way.
Thornton, a physicist, was selected by NASA to become an astronaut in 1984. She flew on the space shuttle Discovery in 1989, Endeavour in 1992 and 1993, and Columbia in 1995, logging more than 975 hours in space, including 21 hours of spacewalks.
Thornton is one of only three women to be inducted into the United States Astronaut Hall of Fame. For more information about Thursday’s event, which is sponsored by Augusta State’s Savannah River Scholars program, call (706) 667-4511.
