If you were asked to name the early astronauts, you probably wouldn’t have much trouble; Neil Armstrong, Buzz Aldrin, John Glenn come to mind easily enough. But what if you had to name women astronauts, besides Sally Ride? It’s a question that even space nerds might have trouble answering.A new book from space reporter Loren Grush centers those women’s stories. The Six: The Untold Story of America’s First Women Astronauts goes deep into the histories, triumphs, and tragedies of Sally Ride, Judy Resnik, Rhea Saddon, Kathy Sullivan, Shannon Lucid, and Anna Fisher. The National Aeronautics and Space Administration excluded women from its astronauts in the 1960s and ‘70s. The agency changed course in 1978, when it selected these six women from a candidate pool of 8,000.Ira sits down with Loren Grush, space reporter for Bloomberg News, to talk about why NASA delayed their inclusion, the agency politics the women had to navigate, the pressure they faced from the media, and how they made their mark on the space program.To stay updated on all things science, sign up for Science Friday's newsletters.
