NASA announced that it had approved the extension of operations for the twin Mars Rovers, Spirit and Opportunity, for up to 18 months. The robotic craft had already surprised engineers and scientists, having completed 11 months of extended activity beyond their successful three-month primary missions. Opportunity had driven more than three miles since arriving at Mars, eight times the distance originally planned, and, in March 2005, had set a new record of 722 feet (220 meters) in a single day's drive. Spirit had driven a shorter distance but was working in a much rougher terrain than Opportunity. Both rovers were exhibiting signs of wear and exposure, and scientists recognized that either mission could end suddenly because of a random part failure. James K. Erickson, Project Manager for the rovers at NASA's JPL, remarked that, despite the wear and the effects of exposure, both rovers remained in exceptional shape. Erickson said that NASA would work to get as much benefit as possible for as long as the craft were capable of producing worthwhile scientific results. Director of NASA's Mars Exploration Program J. Douglas McCuistion added that the rovers' successes had strengthened NASA's commitment to achieving the ambitious goals of returning samples from Mars and eventually sending a human expedition to the planet.
