Amateur Astronomers Avoiding Armageddon: New Shoemaker NEO Grant Awardees

Shoemaker NEO Grant awardees get help with their search for and tracking of Near Earth Objects--asteroids that endanger our planet. The latest group of winners has just been named by the Planetary Society. Planetary scientist Dan Durda led the distinguished selection committee. Robert Holmes is the first double-awardee. Bill Nye is excited about plans for the first solar power satellite. A classic Q&A segment from Emily Lakdawalla, and Bruce Betts checks in from Spain for this week's What's Up and space trivia contest.
