Elon Musk is an entrepreneur and out-of-this-world thinker, who has shaken up two vital industries that were dominated by giant multinational corporations with companies that began life as startups. Tesla's breakthrough with electric cars is well-known, but many of Musk's most stunning innovations have come with SpaceX, which pioneered reusable rockets— slashing the cost of space launches— flew astronauts into space, and landed rockets on boats.

Next is the development of Starship. Musk also wants to send hundreds if not thousands of humans to Mars.

Our guest, Eric Berger, is a senior editor at space and technology news website, Ars Technica, and author of the new book, "Liftoff: Elon Musk and the Desperate Early Days that Launched Space X." He takes us on a fascinating journey, as we look at the remarkable changes in the space race, and what may be coming in the next few years.
