  This image provided by NASA shows a view of the north polar ice cap on Mars taken by NASA's Mars Reconnaissance Orbiter. New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought. The findings suggest any liquid water that might exist below the planet's surface, and any possible organisms living in that water, would be located deeper than scientists had suspected. "We found that the rocky surface of Mars is not bending under the load of the north polar ice cap," said Roger Phillips of the Southwest Research Institute in Boulder, Colo. "This implies that the planet's interior is more rigid, and thus colder, than we thought before," he said. (AP Photo/HO - NASA)
