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.
