Planetary Radio opens a spacetime rift enabling us to talk with Robert Zubrin. Not the Robert Zubrin of our own time who heads the Mars Society, but the one who lives in the 22nd century and has written How to Live on Mars: A Trusty Guidebook to Surviving and Thriving on the Red Planet. Bill Nye's muse is the Moon. Emily Lakdawalla also looks up at our planet's satellite and says there's a whole lotta shakin' goin' on. Bruce Betts and Mat Kaplan have a special prize to award the winner of their latest space trivia contest.
