About The Apollo 11 Mission here.
It took 6 hours to prepare to exit the Lunar Module. At 10:56 p.m. EDT on July 20, 1969, Neil Armstrong became the first human to set foot on the Moon, marking the occasion with these words, "That's one small step for a man, one giant leap for mankind." Unfortunately, a minor break in communications caused the entire world to hear and remember the statement as "That's one small step for man, one giant leap for mankind." The Apollo lunar surface camera, mounted on one of the LM legs, broadcast this event to the world.
Aldrin joined Armstrong on the surface about nineteen minutes later, calling it "Magnificent desolation". As he left the LM, Aldrin said, "Now I want to back up and partially close the hatch - making sure not to lock it on my way out." "A particularly good thought." laughed Armstrong.
Asked later on why they bothered closing the hatch, Armstrong said it was to avoid having someone ask "Were you born in a barn?"
