Decades after we last set foot on the Moon, and several years after the Space Shuttle was retired, space activity is finally leaving the doldrums.  Permanent bases on the Moon and Mars are now within reach, and a new Space Race is brewing, with Asian countries ascendant. Dr. Impey (University of Arizona) reviews the history and landmarks of the international space program, gives a snapshot of the current situation, and plots the trajectory of the future of space travel.  Recorded on Feb. 15, 2017.  (Dr. Impey has written a book with the same title as this talk.)
