Space Policy Edition #19: When did the private space age begin? Much earlier than you think.

Summary: Elon Musk. Jeff Bezos. Richard Branson. These are the names we tend to associate with the current era of private space exploration. But what about John Quincy Adams, James Lick, or Charles Yerkes? Space economist and historian Dr. Alex MacDonald joins us to discuss his book, "The Long Space Age," which chronicles the history of private investment in U.S. space exploration all the way back to the 18th century. Jason and Casey also discuss the consequences of the House GOP tax plan, which could raise taxes on thousands of graduate students. Also, the coming budget showdown and possible consequences for NASA projects.
