Taken by the Mars Reconnaissance Orbiter, this image shows the rover Opportunity (arrow) on the edge of Santa Maria crater with tracks visible on the left side of the picture. The windblown sand in the bottom of the crater is much more apparent in this incredible ground level shot from the rover itself.
Opportunity is nearly seven years into a drive that was designed last closer to seven months. Those tracks? Before long, they'll line out of the image to the right on the way to much, much larger Endeavour crater, the doughty rover's long term destination.
