sends this quote from Universe Today:
"With her most recent drive of 482 feet on June 1, 2011 (Sol 2614), NASA's Opportunity Mars Rover has zoomed past the unimaginable 30 kilometer mark in total odometry since safely landing on Mars nearly seven and one half years ago on Jan 24, 2004. That's 50 times beyond the roughly quarter-mile of roving distance initially foreseen. And Opportunity is still going strong, in good health and has abundant solar power as she continues driving on her ambitious overland trek across the martian plains of Meridiani Planum. She is heading to the giant Endeavour crater, some 22 km in diameter."
