The Physicist Who Flew

On June 18, 1983, the Space Shuttle Challenger lifted off from Kennedy Space Center carrying five crew members, including Sally Ride, a 32-year-old physicist from Los Angeles. She became the first American woman in space. Twenty years after Valentina Tereshkova flew solo for the Soviet Union, the United States finally put a woman in orbit. The delay was not technical. It was cultural.

Ride earned a PhD in physics from Stanford in 1978. That same year, NASA dropped the test-pilot requirement. She applied with 8,000 others and was one of six women selected. Journalists asked questions no male astronaut faced -- about her reproductive system, whether she cried on the job. Ride answered with precision and focused on the work.

The six-day mission deployed two satellites and tested the robotic arm. Ride operated it to release and recapture a satellite -- the first retrieval in space. She flew again in 1984 and was scheduled for a third when the Challenger disaster in 1986 grounded the fleet. She served on the Rogers Commission, asking critical questions that exposed NASA's decision-making failures. She later became a physics professor at UC San Diego and founded Sally Ride Science.

Ride was intensely private. When she died of pancreatic cancer in 2012 at 61, her obituary revealed a 27-year relationship with Tam O'Shaughnessy -- making her the first known LGBTQ astronaut. What she left was a record of competence so clear it became its own argument. She proved gender was irrelevant to spaceflight. The path she cleared has been traveled by dozens since.
