This weekend marks 50 years since the historic first moon landing of 1969.
On July 16, 1969, Apollo 11 lifted off from NASA's Kennedy Space Center in Florida, rocketing astronauts Neil Armstrong, Buzz Aldrin and Michael Collins into space.
Four days later, on July 20, 1969, Armstrong and Aldrin landed Apollo 11's module, the Eagle, on the moon and stepped onto the lunar surface (July 21, NZ time).
An estimated 650 million people watched the televised moon landing and heard Armstrong declare the moment as "one small step for man, one giant leap for mankind", according to NASA.
Here's what mankind has achieved in the five decades since that iconic moment.
