Today, forty years ago, mankind took a giant leap and stepped foot on the surface of our moon. It's a perfect time to celebrate with a look back at the Apollo 11 mission.

In the gallery below, we'll take you through the delivery of the Saturn V to the launch pad, the Earth rising over the moon, to the landing on the lunar surface and the return back to Earth. Enjoy this monumental day as you never truly know where we'll step foot next.
