Planetary scientist and author Jim Bell has just written “The Interstellar Age—Inside the Forty-Year Voyager Mission.” He talks with Mat Kaplan about the magnificent grand tour of the outer solar system that is now headed toward the stars. Emily Lakdawalla shares the latest news about dwarf planet Ceres and the Dawn mission. Bill Nye fondly remembers Leonard Nimoy. The space trivia contest generates a bit of cosmic potty humor on What’s Up.
