Dawn Approaches Giant Asteroid Vesta

After three-and-a-half years of ion-propelled flight, Dawn is finally on final approach to Vesta. We'll get a mission status report from Marc Rayman. No one is more enthusiastic about Dawn than Emily Lakdawalla. Bill Nye appeals for space cooperation with China. Bruce Betts returns from saving the world in Romania to give away a Planetary Radio t-shirt and announce a new space trivia contest.
