She was the first Black woman to get onto the training program in 1987. After more than a year training in Texas, she went to the Kennedy Space Centre in Florida. In 1992, Jemison finally got to go into space on the Endeavour space shuttle. The space shuttle orbited Earth for eight days; Jemison carried out experiments on the spaceship.
