Each week, Planetary Radio visits with a scientist, engineer, project manager, advocate or writer who can provide a unique perspective on the quest for knowledge about our solar system and beyond. We also showcase regular features that raise your space IQ while they put a smile on your face.

Planetary Radio now airs on radio stations across the USA. We hope to add many more stations in the coming months. Let us know if there is a public radio station near you that should have Planetary Radio on its schedule.
