This is the first color image of Mars from the High Resolution Imaging Science Experiment (HiRISE) on NASA’s Mars Reconnaissance Orbiter. This is not natural color as seen by human eyes, but infrared color, shifted to longer wavelengths. The image has been processed to enhance subtle color variations. Seen in the image is what appears to be early-morning fog in the atmosphere. Large-scale streaks are due to the action of wind on surface materials. The blankets of material ejected from the many small fresh craters are generally brighter and redder than the surrounding surface, but a few are darker and less red.
