Sally went to Stanford University, where she studied physics (laws of nature and universe). One day, Sally saw an ad in a school newspaper from N.A.S.A. (the National Aeronautics Space Administration), looking for future astronauts. Sally applied and was accepted. After a long time practicing, in 1983, Sally became the first woman astronaut to orbit Earth in space. She experienced weightlessness and even grew an inch because her spine was not compressed by gravity as it is on Earth. While in space, she performed many experiments, which help people to learn how to adapt to life in space.
