Planetary Radio

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. We hit the road now and then to produce a Planetary Radio Live show in front of an audience.  Drop us a line or enter the weekly space trivia contest at planetaryradio@planetary.org.

Please support your local public radio station that airs the show! Check the station's online schedule or review our online list of affiliates. Satellite radio listeners can hear us Sunday evenings on the Sirius XM Public Radio channel.  Want to hear Planetary Radio on your local station?
