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 July 28, 2014. Opportunity passed 25 miles of total driving on July 27, 2014. A drive of 157 feet (48 meters) brought the mission's total, through that date, to 25.01 miles (40.25 kilometers).
