Planetary Radio, the weekly half-hour series about space exploration, has been available since Tuesday, July 20, 2004, the thirty-fifth anniversary of the Apollo 11 moon landing.

It’s the only long form public radio program devoted to the final frontier. Along with top-flight production quality, every episode relies on the deep expertise of the Planetary Society, founded by Carl Sagan, Lou Friedman and Bruce Murray. We are committed to the high standards your audience expects and deserves.

Whether it’s the launch of Burt Rutan’s SpaceShipOne or the arrival at Saturn of the huge Cassini probe, Planetary Radio is there. We also feature conversations with the men and women who lead the way, from Buzz Aldrin to Arthur C. Clarke, along with the scientists and engineers who provide unique perspectives on the quest for knowledge about our universe. Other regular features like “What’s Up!” raise your space IQ while putting a smile on your face. And you just might win their weekly space trivia contest.
