Sharpest map of Mars surface properties

A heat-sensing camera has provided data to create the most detailed global map yet made of Martian surface properties. Surface properties tell geologists about the physical nature of a planet or moon's surface. Is a particular area coated with dust, and if so, how thick is it likely to be? Where are the outcrops of bedrock? How loose are the sediments that fill this crater or that valley? A map of surface properties lets scientists begin to answer questions such as these.
