It shows a thin coating of water ice / on the rocks and soil. The time the frost appeared corresponds almost exactly with the / buildup of front one Martian year (23 Earth months) ago. Then it remained on the / surface for about 100 days. Scientists believe dust particles in the atmosphere pick up / bits of solid water. That combination is not heavy enough to settle to the ground. But / carbon dioxide, which makes up 95 percent of the Martian atmosphere, freezes and / adheres to the particles and they become heavy enough to sink. Warmed by the Sun, / the surface evaporates the carbon dioxide and returns it to the atmosphere, leaving / behind the water and dust. The ice seen in this picture, like that which formed one Martian year ago is extremely thin, perhaps no more than one-thousandth of an inch thick. / PHOTO CREDIT: NASA or National Aeronautics and Space Administration
