NASA is commemorating 40 years since one of the US space programmes most significant missions to the moon.
The three-man Apollo 16 mission saw astronauts spend 20 hours on Descartes Plateau, known as the "lunar highlands", roving 27 kilometres in their moon buggy and taking high resolution images of the landscape.
Eleven days after the launch, the astronauts performed a perfect splashdown in the Pacific, but the near-perfect mission was followed by just one further manned expedition to the moon's surface.
