Today my guest is author and historian Dr. Margaret Weitekamp. Margaret is chair of the Space History department at the Smithsonian Institution's National Air and Space Museum where she curates the Social and Cultural History of Spaceflight Collection encompassing some 5,000 pieces of space memorabilia and science fiction objects. She is also the author of Right Stuff, Wrong Sex: America’s First Women in Space Program. I was fascinated with the idea of chatting with a space historian and I knew Margaret would be a great choice, so I hope you are sitting comfortably and happy to stay with us.
