Full Name: Sally K. Ride.
Born on May 26, 1951 in Los Angeles, California
In 1968, she graduated from Westlake High School, Los Angeles, California. She received a Bachelor of Science, in Physics, and a Bachelor of arts, in English from Stanford University in 1973.

In January, 1978, Sally Ride was chosen as an astronaut candidate by NASA. Just over a year later, In August 1979, she completed a one year training and evaluation period, which made her eligible for an assignment as a mission specialist on future space shuttle flight crews. Sally performed as an on-orbit capsule communicator on the STS-2 and STS-3 missions.
On June 18, 1983, she was accompanied by Captain Robert L. Crippen, Captain Frederick H. Hauck, the commander and pilot, as well as two fellow mission specialists, on STS-7. She was later chosen to perform the first formation of the flying of the orbiter with a free-flying satellite. Sally Ride was part of the largest crew to fly to date. As of July 2006, she has received a number of honors and awards.

Interesting Fact: In 2001, she pursued her life dream, to teach young girls and women to work as hard as they can to get what they want, and someday they might be as accomplished as her.
