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.

10/07/2016 | 1:03:18

Guests

We take a deep dive into new space legislation working its way through the US Senate. It embraces Mars and NASA's big rocket.

Space Policy Edition #3: Plutonium-238, Europa via SLS, Cost of the Next Mars Rover Rises

08/05/2016 | 1:03:06

Guests

In our third episode, we debate the risks and rewards of tying the future of a Europa mission to the fate of NASA's massive Space Launch System rocket. Also, NASA just announced that the next Mars rover will cost $2.4 billion—$900 million more than initially thought. But the mission is not considered over budget. Why not? Lastly, the U.S. just generated 50 grams of Plutonium-238, the largest amount in nearly thirty years. We celebrate the successful effort to create this critically important, though highly toxic, power source for deep space spacecraft.
