Each week, Planetary Radio’s Mat Kaplan 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. We hit the road now and then to produce a Planetary Radio Live show in front of an audience.

It’s the only long form public radio program devoted to the final frontier. Along with top-flight production quality, every episode relies on the deep expertise of the Planetary Society, founded by Carl Sagan, Lou Friedman and Bruce Murray, and now run by CEO Bill Nye the Science Guy! Bill has a weekly segment on the show.
