MELBOURNE, Fla. — Sally Ride shattered the glass ceiling on June 18, 1983, in dramatic fashion aboard NASA’s space shuttle Challenger to become the first American woman in space.

Now on the 40th anniversary of her first historic spaceflight and 11 years after her death from pancreatic cancer, NASA is preparing to launch the first mission to the moon with a woman onboard.

While going to space is what thrust Ride into the spotlight, it was her advocacy for improving the safety of human spaceflight and her effort to make high-quality scientific education available to more young people that cemented her legacy.

Becoming an astronaut

In 1977, before becoming an astronaut, Ride was a doctoral student studying physics at Stanford University in California. She thought she might end up as a physics professor after earning her Ph.D. in 1978.

“She followed her interest. She followed her heart. And when she got interested in something, she really dove in and gave it her all,” said Tam O’Shaughnessy, Ride’s longtime business and life partner.

Pursuing a career as an astronaut never crossed her mind.

“Many people think that she was like a type A personality, mapped out her whole life, and that couldn’t be further from the truth,” O’Shaughnessy said. “It was really serendipity.”

Until Ride was selected in 1978 alongside five other women, all of NASA’s astronaut candidates had been white men that were test pilots or scientists, often with military experience.

“She was eating breakfast one day in the student cafeteria, and she saw the Stanford Daily, the student newspaper, had an article about NASA recruiting women and women scientists for the very first time,” O’Shaughnessy said. “She thought: I’m a woman. I’m a scientist. I want to go to space.”

She was selected by NASA as part of the agency’s eighth astronaut class, the first to assign astronauts to fly aboard the space shuttle and the first to include female candidates. The six women accounted for just 17% of the 35 newly selected astronaut candidates.

They were among fifteen mission specialist-astronaut candidates who joined one of the pilot astronaut candidates for the training. (1978)

Future astronaut Eileen Collins was a pilot in the Air Force at the time with her sights set on space. She followed Ride’s selection and the attention she received from the media.

“She was breaking barriers and making it more possible for me,” Collins said.

Another woman who found lifelong inspiration in Ride is National Test Pilot School Flight Test Engineer Kate Gunderson.
