Wes Huntress on the NASA Administrator's Resignation and a New Super Mars Rover

Former NASA Associate Administrator for Space Science Wes Huntress brings his expertise to two topics this week, the just announced resignation of Sean O'Keefe, and the selection of instruments for a huge new rover, the Mars Science Laboratory. Emily Lakdawalla considers the weird days and nights on Venus, and Bruce Betts presents plenty of planets and a new trivia contest on What's Up! Space headlines, too.
