In an impressive ceremony at the White House, commemorating the 40 years of the Moon mission, Obama honoured Apollo 11 Mission Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin 'Buzz' Aldrin and hailed them as 'three iconic figures'.
Fifty years ago on July 20, 1969 with these words American astronauts Neil Armstrong, Michael Collins, and Edwin "Buzz" E Aldrin made history by becoming the first human beings to set foot on another world -- the moon. It was an event that was watched by millions on television and one that remains etched in all our memories. Collected here are 17 images of that historic mission, a "giant leap for mankind".
