MAVEN Principal Investigator, University of Colorado Boulder
Mars was once a warm and wet world. Then its dense, protective atmosphere mostly vanished. Learning why was one of the greatest mysteries in planetary science. The answer has just been delivered by the MAVEN orbiter. Principal Investigator Bruce Jakosky will take us through it. Bill Nye the Science Guy co-chairs the March for Science. We’ll talk to him about this new effort and the successful relaunch of a SpaceX booster. Last chance to win a rubber asteroid is in this week’s What’s Up space trivia contest!
