This chart illustrates comparisons among the distances driven by various wheeled vehicles on the surface of Earth's moon and Mars. Of the vehicles shown, the NASA Mars rovers Opportunity and Curiosity are still active and the totals for those two are distances driven as of Aug. 11, 2016.

Opportunity completed its first Mars marathon March 24, 2015 - 26.219 miles (42.195 kilometers) - with a finish time of roughly 11 years and two months.

Curiosity has been roving Mars since 2012. The mission is examining the lower slopes of Mount Sharp, a layered mountain inside Gale Crater, to learn more about how and when ancient environmental conditions in the area evolved from freshwater settings into conditions drier and less favorable for life.
