Timothy Spahr

NEO Sciences LLP CEO and Shoemaker NEO Selection Committee Chair

There’s a place to go when you find a space rock headed our way, or headed any which way.  Tim Spahr directs the Minor Planet Center, the global clearinghouse for all information about asteroids, comets and other relatively small bodies like moons.  Tim also coordinates the Planetary Society's Shoemaker Near Earth Object Grant program. Jason Davis shares his thoughts about a proud return to space, while Bill Nye the Science and Planetary Guy begins his segment with a bang. What’s Up tells you where to look for night sky goodies, and you might win the new Planetary Radio t-shirt.
