NASA sent the shutdown command to the Mars Spirit Rover on May 25, seven years after the exploration vehicle landed. Spirit was scheduled to operate for approximately three weeks and cover a distance of a couple hundred yards. Instead, it operated for more than five years and covered almost five miles. Spirit made its last transmission on March 22, 2010. Spirit‘s sister craft, Opportunity, is still operating.
