Sally Ride was a pioneering American astronaut and physicist who became the first American woman in space in 1983 aboard the Space Shuttle Challenger. Before her historic flight, she earned a Ph.D. in physics and worked as a mission specialist, playing a crucial role in operating the shuttle's robotic arm. After retiring from NASA in 1987, Ride dedicated her life to science education, particularly encouraging young girls to pursue careers in STEM fields. She authored several children's books about space and founded Sally Ride Science, a company dedicated to creating engaging science programs and resources. Her legacy continues to inspire generations of scientists and astronauts.
