NASA's Mars Reconnaissance Orbiter has discovered water that could be 99 percent pure in craters halfway between the north pole and equator of Mars. "We knew there was ice below the surface at high latitudes of Mars, but we find that it extends far closer to the equator than you would think, based on Mars' climate today," said Shane Byrne of the University of Arizona, a member of the High Resolution Imaging Science Experiment, or HiRISE, which runs the high-resolution camera on NASA's Mars...

HiRISE Reveals Rare Polar Impact Craters On Mars An odd, solitary hill rising part-way down an eroding slope in Mars' north polar layered terrain may be the remnant of a buried impact crater, suggests a University of Arizona planetary scientist who studied the feature in a new, detailed image from the HiRISE camera onboard NASA's Mars Reconnaissance Orbiter. HiRISE, or the High Resolution Imaging Science Experiment, headed by Alfred McEwen of the Lunar and Planetary Laboratory, is based at...
