This week's Please Explain is all about the National Aeronautics and Space Administration (NASA)! We pull back the curtain on the institution that explores the mysteries of our universe. Dr. Valerie Neal, curator, chair of the Space History Department at the Smithsonian National Air and Space Museum and author of Spaceflight: A Smithsonian Guide and Where Next, Columbus? The Future of Space Exploration, joins us to talk about the inner-workings of NASA and to answer questions from listeners.
