Planetary Radio

Let The Planetary Society’s weekly podcast take you to the outer reaches of the solar system and beyond. Host Mat Kaplan visits with scientists, engineers, mission leaders, astronauts, advocates, and writers who provide their unique and exciting perspectives on the exploration of our universe. New episodes are published every Wednesday.

We are proud to feature Planetary Radio: Space Policy Edition on the first Friday of every month. Mat and The Planetary Society's Chief Advocate, Casey Dreier, dive deep into the policy and politics behind what we do and where we go in space.
