Opportunity celebrated the driving milestone this week as it headed toward its next destination, Endeavour crater.
The aging but plucky rover still has another 7 1/5 miles to go to reach the crater.
Since landing in 2004, Opportunity and its twin Spirit have outlasted their original three-month mission.
Unlike the freewheeling Opportunity, Spirit is stuck in a sand trap.
Its power has been declining with the coming winter and is expected to go into hiberation mode.
Before it became stuck, Spirit had logged nearly five miles on its odometer.
