Crater Down Below
Scientists believe the circular feature in this image to be a crater near the Mars Exploration Rover Opportunity. The rover landed at Meridiani Planum on Mars at approximately 9:05 p.m. PST on Saturday, Jan. 24. This image was taken at an altitude of 1,986 meters (6,516 feet) by the descent image motion estimation system camera located on the bottom of the rover. The image spans approximately 1.6 kilometers (1 mile) across the surface of Mars.
