Ice On Mars

NASA scientists have identified the mysterious white substance uncovered by the Phoenix Lander as ice. Using Phoenix's stereo camera the substance was caught in the act of disappearing under the martian sunlight. The substance "sublimated", or transformed directly from a solid to a gas without passing through the liquid state. Sublimation is a characteristic of how water behaves on Mars according to spaceweather.com.
