The dinosaurs regret their lack of a space program. 200 million years later, humans are gearing up to defend themselves from a species-ending rock. The many challenges involved are addressed in a new strategic action plan created by sixteen agencies of the US government. NASA’s Planetary Defense Officer, Lindley Johnson, and his associate, Kelly Fast, take us inside the plan. Planetary Society CEO Bill Nye the Science Guy applauds the growing worldwide attention to Near Earth Objects. By the time you read this Hayabusa2 will have reached asteroid Ryugu. Senior editor Emily Lakdawalla has a mission update. And Bruce Betts is all over Asteroid Week in a new What’s Up segment.
