Ralph Lorenz

Planetary Scientist for Johns Hopkins University Applied Physics Lab

Planetary scientist Ralph Lorenz has co-authored a great new book about Saturn's moon and the Cassini-Huygens mission that has revealed its amazingly Earth-like surface. Emily Lakdawalla reaches for robotic arms on Mars, and there's a sweet edition of What's Up with Bruce Betts and Mat Kaplan that will give away another Planetary Radio t-shirt in a new space trivia contest.
