Description
This image, taken by the microscopic imager on the Mars Exploration Rover Opportunity, shows a geological feature dubbed "Robert E." Light from the top is illuminating the feature, which is located within the rock outcrop at Meridiani Planum, Mars. Several images, each showing a different part of "Robert E" in good focus, were merged to produce this view. The area in this image, taken on Sol 15 of the Opportunity mission, is 2.2 centimeters (0.8 inches) across.
