. This wide-angle image (spanning 320 miles [510 km]) shows different compositions in the material on MercuryтАЩs surface. The camera used three of the 11 filters available to take this image. (The wide-angle camera can image in 11 filters across the range of visible to near-infrared radiation.) This image combines data taken at 1,000 nanometers (red), 750nm (green), and 430nm (blue) to create a color image.
