10th Anniversary of 9/11 on Mars

This picture shows an American flag on metal recovered from the site of the World Trade Center towers shortly after their destruction on September 11, 2001. The aluminum component bearing the image of the flag serves as the cable guard of the rock abrasion tool (RAT) built and operated by Honeybee Robotics of New York. Opportunity took the component images that went into this picture on Mars on the 10th anniversary of the attacks on the towers, September 11, 2011. The rover used both its stereo panoramic cameras to record several exposures during its Sol 2713, which were then combined into this one picture. The image is approximate true Martian color, or color as the human eye would see it on Mars. The black-and-white portion of the view, providing context, comes from the rover's navigation camera.
