GOOD EVENING: The show begins in Charlie Chaplin's studio in Hollywood -- he owned everything -- where he created the genius of The Great Dictator (1940), a mocking slapstick about the Hitlerites that was an accurate prelude to the horror. Then to the planet Earth without humans, asking how canines would fare without masters. To New South Wales after 13 days of rain, breaking records and welcoming a La Niña winter. To the asteroid belt, looking forward to a conversation in the coming weeks about a sample return mission to Bennu.
