Celebrating the anniversary of mankind's giant leap in 1969

It was 10:56 p.m. on July 20, 1969 when NASA astronaut Neil Armstrong prepared to become the first human to step foot on another world. 

With the world watching, Armstrong climbed down the ladder of Apollo 11 onto the surface of the moon and uttered the most famous words in space history: "That's one small step for a man, one giant leap for mankind."

Armstrong, along with fellow astronauts Buzz Aldrin and Michael Collins would splash down in Hawaii four days later. The only things they would leave behind would be an American flag, a patch honoring the crew of the fallen Apollo 1 and a plaque that read: "Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind."
