As if extremes of temperature and lack of air weren’t enough! Some scientists believe it’s space radiation that will keep humans from venturing deep into our solar system. Not so, say three teams of NASA Innovative Advanced Concepts (NIAC)-funded researchers. Each is exploring a cutting-edge approach to protecting astronauts on their way to Mars and other destinations. Emily Lakdawalla proudly announces the new Planetary Society website, while Bruce Betts and Mat Kaplan look to the sky in our What’s Up segment as they announce a new space trivia contest. Bill Nye is away.
