Sally Ride was born on May 26th, 1951, in California. She started to play tennis at the age of 10 and became a good tennis player. But later, she thought she was not good enough to become a successful tennis player and then gave it up.

At the age of 22, she got a doctor’s degree. She was looking for a job when she read about NASA’s call for astronauts. More than 8,000 people wanted to join in the space program, but only Sally and other thirty-four other people were accepted.
