Sally Ride (May 26, 1951 – July 23, 2012) was an American physicist and astronaut. She joined NASA in 1978, and in 1983 became the first American woman in space. She was the third woman in space overall, after Soviet cosmonauts Valentina Tereshkova (1963) and Svetlana Savitskaya (1982). Ride had completed eight months of training for her third flight when the Space Shuttle Challenger disaster occurred. She served on the two panels that investigated this accident and the Space Shuttle Columbia disaster.Photograph credit: NASA; restored by Coffeeandcrumbs
