We’ve already brought you Planetary Radio Live from the 2015 PDC near Rome, Italy. Now you’ll hear a small sampling of the scientists, engineers, policymakers and media experts who spent five days considering how humanity will respond to a potentially disastrous threat. Bruce Betts celebrates the great Jupiter-Venus conjunction in What’s Up. Bill Nye and Emily Lakdawalla return next week.
