In December 1972, two men went for a drive on the moon. They were Apollo 17 astronauts Eugene Cernan and Harrison ¡°Jack¡± Schmitt of the United States¡¯ National Aeronautics and Space Administration (NASA).

The 20-km round trip took over seven and a half hours, and ventured no more than under 8 km from the lunar module, the spacecraft that allowed the astronauts to land on the moon. Yet it remains the furthest any human has traveled across a celestial body other than Earth.

The distances that robots have covered are only slightly longer. The winning rover is NASA¡¯s Opportunity, which between 2004 and 2018. On the lunar surface, the Soviet Union¡¯s Lunokhud 2 rover holds the record with 39 km traversed in 1973.
