Sally Ride was the first American woman to rocket into space. Eileen Collins was the first woman to command the Space Shuttle. These two astronauts changed history and broke a very high glass ceiling for little girls. But they traveled different paths to get to NASA and achieve their dreams. Sally Ride graduated from an elite private school in Los Angeles and earned a doctorate in Physics at Stanford, while Eileen Collins was raised in public housing in upstate New York and joined the U.S. Air Force, where she became a test pilot. In this episode, both women talk about the obstacles they overcame to reach the highest of heights.
