Yesterday, the day before Amelia Earhart’s 115th birthday, Sally Ride joined the skies for a final time. At 61, she died of pancreatic cancer—a horrible disease. Back in 1983, it was thrilling to watch her smash the American gender barrier as she zoomed into space. When she headed off into the final frontier, it was not as it was with the subordinate Lieutenant Uhuru on the Enterprise—the closest analogue there was at the time—but as an equal astronaut. Ride strode up to the Challenger as if she belonged there—which, of course, she did. She had degrees in physics, astrophysics, and English—what an underachiever! When she saw a NASA newspaper ad seeking astronauts, she applied and got the job.
