Weird 'Endurance' Rock Ahead

This image taken by the Mars Exploration Rover Opportunity shows a bizarre, lumpy rock dubbed "Wopmay" on the inner slopes of "Endurance Crater." Scientists say the rock's unusual texture is unlike any others observed so far at Meridiani Planum. Wopmay measures approximately 1 meter (3.3 feet) across. The image was taken by the rover's panoramic camera on sol 195 (Aug. 11, 2004). Opportunity will likely travel to this or a similar rock in coming sols for a closer look at the alien surface.
