On July 20, 1969, at 10:56 p.m., half a billion people across the globe -- or a full one seventh of the Earth's population at the time -- tuned into their televisions to watch the climax of a very long journey. The footage was grainy and the sound scratchy, but the planet was gripped by the live images of astronaut Neil Armstrong descending a ladder from the Apollo 11 lunar module to become the first human being to step foot on a surface that wasn’t Earth’s. It was to this rapt international audience that Armstrong uttered the famous words: "That's one small step for man, one giant leap for mankind."
