On April 16, 1972, Charlie Duke, John Young and Ken Mattingly lifted off in their Saturn V on the fifth manned lunar landing mission. Duke would spend three days on the moon, collecting rock and soil samples, and driving the Rover over its surface. On this 40th anniversary of the first moon mission, Larry talks with Duke about the first landing mission to the moon and his own moonwalk.
