Sally Ride was a very famous American physicist and an astronaut who also came to be the first American woman in space, thus breaking the gender barrier in science and space exploration. When she was the NASA mission specialist, she became a role model for many generations to come by being assertive, smart, and curious through the use of her very qualities. In fact, she was the first American female astronaut and a very great scientist, but she always remained a good mentor and facilitator for young people, especially girls, in the scientific fields. Her legacy is a symbol of equal opportunity, determination, and learning power that is no longer limited.
