A gorgeous introduction to the twelve brave men who have left footprints on the moon, just in time to celebrate the fiftieth anniversary of the first lunar landing.

Over the course of the next three-and-a-half years, twelve lunar explorers, including Alan Shepard and Gene Cernan, touched down on the moon's surface.
