Ride was born on May 26, 1951, in Encino, California. Growing up, she excelled at tennis and went on to play in college. Her other great passion was science.
“I was fascinated by whether there might be life on Mars,” Ride told Scholastic News in 2008. “I was fascinated by the stars.”
Ride eventually chose science over tennis. At the time, that wasn’t a common career path for a woman. In 1970, women held only 7 percent of the STEM (Science, Technology, Engineering, and Mathematics) jobs in the U.S.
Still, Ride was determined to follow her dream. By 1977, she had earned three college degrees from Stanford University. She was working on a fourth when she saw an ad in the school newspaper. NASA was looking for new astronauts—and for the first time, women could apply.
“I always dreamed of going into space,” Ride said. “The moment I had that chance, I jumped at it.”
More than 8,000 people applied, and only 35 were selected for astronaut training. Ride was one of the six women chosen.
