Apollo 11, the first manned lunar landing mision, was launched on 16 July 1969. Four days later, at 10.56.15pm EDT on 20 July 1969, astronauts Neil Armstrong and Edwin 'Buzz' Aldrin climbed down the steps of the Lunar Module to become the first humans to set foot on another planetary body. "One small step for man, one giant leap for mankind", were Armstrong's famous words as he reached the surface. The third member of the crew, Michael Collins, remained in lunar orbit.
