The Odyssey of the Plutophiles: Alan Stern and David Grinspoon on the Voyage of New Horizons

In July of 2015, a spacecraft called New Horizons gave humankind its first close-up view of a small, misunderstood world called Pluto. It took almost 10 years for New Horizons to soar across more than 3 billion miles of space and give us our first meeting with Pluto and its family of moons.

But that journey is just a small part of a much bigger and more harrowing story of how New Horizons came to be. It was a mission that was decades in the making, an endeavor that endured several near-death experiences, from its early planning stages all the way to the eve of its encounter with Pluto.

Our guests are now telling this incredible story in the new book Chasing New Horizons: Inside the Epic First Mission to Pluto, having experienced this adventure first-hand and from two very different perspectives. Alan Stern is the principle investigator of the New Horizons mission, and his co-author, David Grinspoon, is an astrobiologist, author, and advisor to NASA who witnessed the New Horizons saga as it unfolded and helped to bring its story to life.
