SUMMARY: NASA's Spirit Rover has found a rock that seems to have been acted on by water in the past. The rock is called "Mazatzal", and lies partially buried near the rim of the Crater Bonneville; its light-toned appearance caught the eye of NASA scientists. Spirit used its rock abrasion tool to grind under the surface, and found a darker interior with a bright stripe that cut across both layers. This seems to indicate a fracture that water flowed through. More data about the rock is being transferred back to Earth while Spirit drives to Columbia Hills, located 2.3 kilometres away.
