In pictures: Remembering the last man to walk on the Moon
American astronaut Eugene Cernan was the last man to leave a footprint on the Moon's surface during NASA's Apollo 17 mission in December 1972. Cernan was one of only three people to go to the Moon twice. En route to Moon, Cernan's crew captured an iconic photo of Earth with an entire hemisphere fully illuminated, popularly remembered as 'Blue Marble'.
