Sally Ride, 1951 – 2012

America's first woman astronaut died Monday at the age of 61, of pancreatic cancer. Sally Ride was an inspiration to millions, and not just girls and women. I remember what a triumph it felt to me, back in 1983, when she rode Challenger into space, ending once and for all the perception that American space travel was solely the domain of men. Nowadays, women fly missions all the time, and sometimes command them. It's easy to forget that as recently as the early 1980's, women were simply not part of the NASA equation. The Soviet Union had sent a woman, Valentina Tereshkova, into space twenty years earlier, but that had not signaled a general welcome of women into the Soviet space program. In the case of Sally Ride, it really was the shattering of a glass ceiling. After the loss of Challenger in 1986, Dr. Ride was named to the presidential commission that investigated the cause of the tragedy. She later went on to found Sally Ride Science, an organization devoted to supporting girls’ and boys’ interests in science, math and technology.

Here was a woman who made a difference. It's sad to see her passing. Godspeed, Sally Ride.
