Originally, NASA excluded women from space flight. Eventually, NASA relented and opened the application process to everyone, regardless of race or gender. From a 1977 candidate pool of 8,000, six elite women were selected--Sally Ride, Judy Resnik, Anna Fisher, Kathy Sullivan, Shannon Lucid, and Rhea Seddon. Journalist Loren Grush shows these brilliant and courageous women enduring claustrophobic--and sometimes deeply sexist--media attention, undergoing rigorous survival training, and preparing for years to take multi-million-dollar payloads into orbit.
