Ever wonder what goes on at an international meeting of planetary scientists? Who hasn’t?! This special episode of Walkabout comes to you from a hotel room in Geneva Switzerland following the joint meeting of the American Astronomical Society’s planetary science division and the European Planetary Science Congress. Josh and Addie are joined by original Top Quark Dr. Tracy Becker and Dr. Bonnie Meinke for a free-wheeling discussion of highlights from the meeting, the solar system’s most recent visitor from interstellar space, and new findings about how an ancient asteroid collision helped diversify life on planet Earth.
