The National Geographic Channel’s “Mars” miniseries has begun. Mat Kaplan attended a kickoff for the ambitious docudrama last summer. You’ll hear from series technical advisor Bobby Braun, author of “The Martian” Andy Weir, Cosmos creator Ann Druyan and more. It took two years, but Emily Lakdawalla has completed an important visual document focused on Mars rover Opportunity. Bill Nye steps aside for Planetary Society Director of Space Policy Casey Dreier with a look toward Donald Trump’s NASA. One listener will win a spectacular new Pluto globe in the What’s Up space trivia contest.
