The Journey To Palomar -- A New Documentary

We journey to the Palomar Observatory to visit with filmmakers Robin and Todd Mason who have created a great new public television documentary about George Ellery Hale, builder of what were the largest telescopes on Earth. Bill Nye looks back over the Phoenix mission with hope for the future. Emily Lakdawalla's Q&A brings a page from the Martian calendar to our own planet. And you'll learn how to win PlanRad's sixth anniversary contest on What's Up, as Bruce Betts tells Mat Kaplan about the night sky. A new weekly space trivia contest, as well.
