Phoenix May Have Discovered Ice Crumbs on Mars

The NASA Phoenix Mars Lander has reportedly found dice-sized ice crumbs that may have melted after being uncovered more than four days ago. As Phoenix dug around and took images of the Martian soil, scientists noticed several small cubes that vanished over a span of a several days.

"It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question whether the bright material was salt. Salt can't do that."
