 This is CBS Eye on the World, Hotel Mars, Episode N. I'm John Batchelor. David Livingston, Dr. Space of the Space Show, is here as my colleague and co-host. And we're very, very privileged to welcome Eric Berger of Ars Technica, the author of Liftoff, Elon Musk and the Desperate Early Days that Launched SpaceX. It's an exciting story. It has a great punchline.
