Ann Druyan on New Honors for Carl Sagan

NASA has just announced the Carl Sagan Postdoctoral Fellowships in Exoplanet Exploration. His widow and longtime collaborator, Ann Druyan, was part of the celebration, and tells us how she is continuing their work. Bill Nye was one of Carl's students! He shares memories in his own tribute. Emily Lakdawalla is listening for the first live sounds from Mars, and Bruce Betts is on the road for this week's What's Up view of the night sky. He and Mat give away yet another Planetary Radio t-shirt in the space trivia contest.
