PASADENA, Calif., March 25 (UPI) -- NASA scientists say the Mars Exploration Rover Opportunity has surpassed 12.4 miles (20 kilometers) of total driving since it landed on Mars Jan. 25, 2004.
On a Wednesday drive that occurred on the 2,191st martian day, or sol, of the mission, the rover covered 220 feet southward as part of its long-term trek toward Endeavour Crater to the southeast, the space agency said.
