In 2015, the New Horizons Spacecraft flew past Pluto. Because Pluto is so far away, it took nearly 10 years of travel for the spacecraft to reach that distant dwarf planet — and that was after a decade of work to get the spacecraft to the launch pad. Planetary scientists Alan Stern and David Grinspoon have written a new book, called: “Chasing New Horizons: Inside the Epic First Mission to Pluto”. The book tells the story of developing and operating the New Horizon mission.
How on Earth’s own Joel Parker is also a scientist on the New Horizons mission, and he had a chance to chat with Alan and David about their book. Last week we heard the first part of this interview. In today’s show, we present Part 2 of that interview. You can also listen to the full extended interview.

Planetary science budget (start time: 15:49). Despite the successes of the Mars missions and voyages to our other planetary neighbors, the White House decided that NASA’s planetary science budget should be drawn down. The hit would be substantial, a twenty percent reduction from 2012. 300 million dollars would be removed from a baseline one and a half billion dollars. We ask Dr. Alan Stern, who has served as the chief of the Science Mission Directorate at NASA, about why the planetary science budget should be restored.
