"One small step for man, one giant leap for mankind." That sentence, uttered by NASA astronaut Neil Armstrong from the surface of the moon 45 years ago, signaled the dawn of a new age.

This month marks the 45th anniversary of the epic Apollo 11 flight that landed the first humans on the moon and safely returned them to Earth. Armstrong, Buzz Aldrin and Michael Collins launched from Florida on July 16, 1969. Armstrong and Aldrin ventured out onto the lunar surface on July 20, 1969. The two men spent 21.5 hours on the moon before taking off from the lunar surface to meet up with Collins in the command module and fly back to Earth.
