Science fiction writer and physicist Greg Benford joins his physicist brother Jim in talking about their work on microwave propulsion. They've already had success in the lab at NASA's Jet Propulsion Laboratory. Next might be the Planetary Society's Solar Sail!

Q&A describes how long you could stay alive in space (not long!). Finally, 'What's Up?' offers our first planetary trivia contest!


No trivia contest spoilers please!
