Looking Back at the Phoenix Mars Polar Lander With Peter Smith

The Phoenix Lander is dead - probably - but it lives on in the reams of data it returned from the red planet, including data about the water ice it found. Principal Investigator Peter Smith reviews the mission. Bill Nye invites you to a celebration of the Mars Exploration Rovers. Emily Lakdawalla also takes us to Mars, and Bruce Betts joins Mat Kaplan for our weekly review of the night sky and a new space trivia contest.
