An Imminent Asteroid Encounter
Spain’s La Sagra Observatory discovered Asteroid 2012 DA14 just a year ago. Now it’s nearing Earth once again. Jaime Nomen of La Sagra is back to prepare us for this very close flyby. 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!
