30 Years ago on June 18, 1983, Sally Ride flew into space aboard the Challenger mission STS-7. She was the first American woman to travel to space. She paved the way for 44 more American women who have so far become astronauts, in addition to countless more in the future. This year in 2013, four out of the eight astronauts are women. Sally Ride passed away last July, but she remains an inspiration to women in science. Mission patch for the STS-7 mission. #challengermission #N
