Each week, Planetary Radio visits with a scientist, engineer, project manager, astronaut, advocate or writer who provides a unique and exciting perspective on the exploration of our solar system and beyond. We also showcase regular features that raise your space IQ while they put a smile on your face.  Host Mat Kaplan is joined by Planetary Society colleagues Bill Nye the Science Guy, Bruce Betts, and Emily Lakdawalla.
