Study: Mars Once Was Wet All Over
Minerals in the soil of Mars show it was once covered by lakes, rivers and other bodies of water that could have supported life, U.S. researchers reported on Wednesday, July 16, 2008. Last month the Mars Phoenix Lander found ice on the surface of the planet, but it is frozen hard. A team of scientists shows that the ice is left over from warmer, wetter times. The team used the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on board NASA's Mars Reconnaissance Orbiter to look at colors in reflected sunlight.
