Mae Jemison is an American engineer, physician, and former NASA astronaut. She became the first African-American woman to travel into space when she served as a mission specialist aboard the Space Shuttle Endeavour in 1992. She is also a trained medical doctor, served as a Medical Officer in the Peace Corps and currently runs BioSentient Corp, a medical technology company. Since Mae wanted to be a scientist, she faced double discrimination as an African-American woman. There had also been few African-American astronauts and no African-American female astronauts prior to Mae’s selection in 1987. She overcame all of these obstacles.
