MIT observations give precise estimate of Mars surface ice

A team of planetary scientists from MIT has found that the southern pole of Mars contains the largest deposit of frozen water in the inner solar system (not counting Earth). According to Maria Zuber (MIT professor of geophysics), the results showed that water, not carbon dioxide, is the predominant frozen liquid found in the southern polar region of Mars. Zuber said scientists have suspected that the southern polar cap of Mars is comprised of a thin veneer of carbon dioxide that rests atop a layer of dust and ice. However, scientists have also observed a surrounding area that is much larger than the polar cap that is dark and smooth, and it wasn’t determined whether the region was also composed of dust or ice, or even both.
