6. Apollo 11
It's probably the most obvious choice on this list, but the simple fact is Apollo 11 was the first mission to put a man on the Moon. The Moon, man! The Moon!
The problem these days is that science-fiction TV shows and movies have spoilt us. We assume that messing around in space is as easy as it looks in Star Trek. But the fact is, humans are pathetically weak and require a ludicrous amount of molly-coddling in order to stay alive.
Apollo 11 not only managed to keep its crew alive, plonk them on the surface of the Moon and take off again, it also returned them safely to the surface of the Earth so they could tell us how amazing the view is up there and make us all sick with jealousy.
