The European Space Agency’s magnificent Rosetta mission ended last week as the spacecraft gently touched down on the comet it has revealed. You’ll hear highlights of the final countdown, and Emily Lakdawalla’s impressions gained at the European Space Operations Center. Bill Nye was there to hear Elon Musk explain his plans to colonize Mars. Bruce Betts gets the comfy chair in this week’s What’s Up segment.
