Leaders of the quest to find, understand and protect ourselves from the asteroids and comets called Near Earth Objects gathered with host Mat Kaplan for a live conversation about this existential threat from space. This special episode presents excerpts of that lively discussion with JPL Senior Research Scientist Amy Mainzer, Manager of NASA/JPL’s Center for Near Earth Object Studies Paul Chodas, and NASA’s Planetary Defense Officer Lindley Johnson. Also on stage was Planetary Society Director of Science and Technology Bruce Betts. Bruce stayed for this week’s What’s Up segment.
