'Tuktoyuktuk' Up Close
This image taken by the Mars Exploration Rover Opportunity shows a target dubbed "Tuktoyuktuk" on a rock called "Inuvik" in "Endurance Crater." Opportunity dug a hole into the target with its rock abrasion tool, then captured this picture with its microscopic imager on sol 188 (Aug. 4, 2004). The image mosaic is about 6 centimeters (2.4 inches) across.
