NASA Extends Mars Rovers’ Mission NASA

NASA has approved an extended mission for the Mars Exploration Rovers, handing them up to five months of overtime assignments, as they finish their three-month prime mission.
The first of the two, Spirit, met the success criteria set for its prime mission. Spirit gained check marks in the final two boxes on April 3 and 5, when it exceeded 600 meters (1,969 feet) of total drive distance and completed 90 martian operational days after landing.
