Neil Armstrong: First man on the moon

Apollo 11 astronaut Neil Armstrong, right, trudges across the surface of the moon leaving behind footprints, July 20, 1969. The U.S. flag, planted on the surface by the astronauts, can be seen between Armstrong and the lunar module. Edwin E. Aldrin is seen closer to the craft. The men reported the surface of the moon was like soft sand and they left footprints several inches deep wherever they walked. (AP Photo)
