Chasing New Horizons to Pluto with Alan Stern and David Grinspoon

The New Horizons mission was a triumph, revealing Pluto as an utterly unique and beautiful world. But the mission first had to survive challenge after challenge, fighting to be developed, meeting a nearly impossible launch deadline, and then narrowly avoiding disaster when it was barely a week from its destination. The entire dramatic tale has now been told by Principal Investigator Alan Stern and his co-author, astrobiologist David Grinspoon.  They join Mat Kaplan to talk about their book, Chasing New Horizons—Inside the Epic First Mission to Pluto.  A signed copy of the book will go to the winner of this episode’s space trivia contest.  Emily Lakdawalla has returned from an international gathering of Mercury scientists with a special report.  The Planetary Society’s Senior Editor also marks the launch of a Chinese lunar orbiter.  Learn more about this week’s topics and see images here: more about your ad choices.
