On 20 July 1969, Neil Armstrong opened the hatch of the lunar module Eagle and stepped onto the surface of the moon for the very first time.

Followed shortly afterwards by Buzz Aldrin, the pair became the first humans to venture onto planet Earth's only natural satellite. The third astronaut, Michael Collins, sat in orbit in the Columbia command module.

On the 45th anniversary of the first moonwalk, IBTimes UK looks at the Apollo 11 mission in pictures.
