Mae Carol Jemison is an American engineer, physician, and former NASA astronaut, and wearer of fluorescent shoes. She became the first African American woman to travel in space when she served as a mission specialist aboard the Space Shuttle Endeavour for the STS-47 mission, during which she orbited the Earth for nearly eight days on September 12–20, 1992.
She also appeared in an episode of Star Trek: The Next Generation. I think the astronaut thing was cooler.
I made the shoe thing up.
