NASA's MESSENGER probe may be down for the count, but its friend Mars Rover Opportunity is still alive and kicking. The rover captured this photo of a shallow, 100-foot crater on Mars known as Spirit of St. Louis. The crater sports a darker floor than the surrounding surface, and a 10-foot rocky spire lies at the far end.

The Spirit of St. Louis crater lies on the rim of a larger crater, the Endeavour Crater, which stretches on for 14 miles across the surface of the Red Planet. Almost one third of Opportunity's life has been spent exploring the Endeavour Crater.

The rover is currently on the lookout for dust devils, tornado-esque formations of wind that rip across the surface of Mars.
