Last man to walk on moon dies at 82

US astronaut Eugene Cernan, the last man to set foot on the moon, died Monday at age 82, Nasa and his family said. Cernan was the spacecraft commander of Apollo 17 -- his third space flight and the last scheduled US manned mission to the moon -- in December 1972. Cernan spent 566 hours and 15 minutes in space -- logging more than 73 hours on the moon's surface.
