In July 2015, the New Horizons spacecraft flew by Pluto, revealing its surface to our view for the first time. In this program, Drs. Alan Stern and David Grinspoon give us an insider's view of how this complex mission came to be and what it discovered at the edge of our solar system.  Their recent book  (with the same title) tells the full story of the mission, its ground-breaking discoveries at Pluto, and where it's going next.  Here is the story of path-breaking exploration and new science, straight from the source, with insight into what it's like to be part of a  planetary mission that goes to a destination never before visited.  (Recorded May 15, 2018)
