We pay another visit to the queen of planets with Cassini Mission Project Scientist Linda Spilker. She always brings us fascinating news from Saturn, its moons and rings. Emily Lakdawalla says John Carter really is on Mars…sort of. Bill Nye celebrates some good news for planetary science in the form of Plutonium, and Bruce Betts provides another guided tour of the current night sky. Another listener will win Bill Nye’s voice on his or her answering system!
