"More than seven years into what was planned as a three-month mission on Mars, NASA's Mars Exploration Rover Opportunity has driven more than 20 miles, which is more than 50 times the mission's original distance goal.
A drive of 407 feet (124 meters) completed on July 17 took Opportunity past the 20-mile mark (32.2 kilometers). It brought the rover to within a few drives of reaching the rim of Endeavour crater, the rover's team's long-term destination since mid-2008. Endeavour is about 14 miles (22 kilometers) in diameter, and its western rim exposes outcrops that record information older than any Opportunity has examined so far. The rover is now about eight-tenths of a mile (about 1.3 kilometers) from the site chosen for arriving at the rim.
'The numbers aren't really as important as the fact that driving so much farther than expected during this mission has put a series of exciting destinations within Opportunity's reach,' said Alfonso Herrera, a rover mission manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. who has worked on the rover missions since before launch in 2003."
