NASA's Mars rover Opportunity has found an unusual  pattern of cracking on a rock it discovered inside a Martian crater -- evidence, perhaps, that water may once have soaked parts of the crater bed, researchers said yesterday.

NASA's Opportunity Mars rover has come across  an interesting object&nbsp;-- perhaps a meteorite sitting out in the open at Meridiani  Planum. Initial data taken by the robot's Mini-Thermal Emission Spectrometer  (Mini-TES) is suggestive that the odd-looking rock is made of  metal.

NASA's Mars rover Opportunity is closing in on what may be the grandest overlook and richest science trove of its long mission. During the next two weeks, the robotic geologist is likely to reach the rim of a hole in the Martian surface wider and deeper than any it has visited.
