Emily Lakdawalla is touched by a tribute to fallen astronauts on Mars.  Bill Nye presents more evidence that the time has come for commercial space development. Bruce Betts and Mat Kaplan think there's a bowl over our heads that is pretty super. They also present the chance to win a Planetary Society hoodie.  NOTE THE LINK TO THE NEW WHAT'S UP!
