Each week, Planetary Radio visits with a scientist, engineer, project manager, advocate or writer who provides 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.

Throughout 2009, Planetary Radio's Emily Lakdawalla and Mat Kaplan are contributing to the IYA 365 Days of Astronomy podcast.

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