Co-Founder and Executive Director Emeritus, The Planetary Society
Planetary Society Executive Director Louis Friedman has just returned from China, where he got a first-hand look at that nation's growing space program. He talks about his impressions on this week's show. Emily Lakdawalla explains why we don't see even the biggest individual components of Saturn's rings on Q&A, and Bruce Betts gets obtuse in this week's What's Up look at the night sky. A new space trivia contest and space headlines, too.
