This image taken by the microscopic imager instrument located on the Mars Exploration Rover Opportunity's instrument deployment device, or "arm," shows the crater floor at Meridiani Planum, Mars, before the rover dug a trench on sol 23 (February 16, 2004). Grains of soil on the floor appear sand-sized with millimeter-sized pebbles on top. The area in this image measures approximately 3 centimeters (1.2 inches) across.
