Genesis Rises From the Ashes/Planetary Protection

Incredibly, after a terrible impact, scientists believe some of the solar wind samples from the Genesis spacecraft can be saved. Genesis team member Roger Wiens updates us from the Dugway Proving Grounds in Utah. We also use the crash as the starting point for a discussion of planetary protection with ecologist Margaret Race. Emily Lakdawalla lets us know whether its better to have a big rock come down on land or in the ocean, and Bruce Betts has to contest with a leaf blower to deliver the new trivia contest.
