An amazing photo mosaic gives a rover's-eye view of a dust devil that swirled across Mars last month.
Opportunity photographed the dust devil with its navigation camera on April 1, as the six-wheeled robot explored steep slopes along the rim of the Red Planet's Endeavour Crater.
New Jersey-based scientist and journalist Ken Kremer and his imaging partner Marco Di Lorenzo colorized six of Opportunity's navcam images, rotated them 10 degrees and stitched them together to create the mosaic.
The duo also made a new route map, showing where the golf-cart-size Opportunity has gone since it landed on Mars in January 2004, a few weeks after its twin, Spirit.
Spirit and Opportunity set out on three-month missions to hunt for signs of past liquid water on Mars. Both robots found plenty of such evidence, and just kept rolling along; Spirit stopped communicating with its handlers in 2010, and Opportunity is still going strong.
To date, Opportunity has covered 26.58 miles (42.78 kilometers) of Martian terrain — the greatest distance ever traveled by a vehicle on the surface of another world.
