Society President Wes Huntress and a Little Guy Named Biff

A visit with Planetary Society President and former NASA Associate Administrator Wes Huntress this week, and then a decidedly different introduction to Biff Starling, one of two astrobots about to leave for the red planet on the Mars Exploration Rovers. You'll also hear the new names of those big rovers, given to them by a nine-year-old girl. Questions and Answers with Emily Lakdawalla returns next week.
