Not of this Earth
This sweeping look at the unusual rock outcropping near the Mars Exploration Rover Opportunity was captured by the rover's left panoramic camera. Scientists believe the layered rocks are either volcanic ash deposits, or sediments laid down by wind or water. Opportunity landed at Meridiani Planum, Mars on January 24 at 9:05 p.m. PST.
