Exposures taken through separate red, green and blue filters are used to create a color image of Mars. The red filter shows the best surface detail. Mars' atmosphere scatters blue light, much like that of Earth, thus Martian surface detail is obscured in the blue filter exposure which permits clouds to be seen easily. A polar hood of clouds over Mars' north pole is evident and a thin sheet of morning clouds can be seen on the western limb.
