A well-traveled NASA Mars rover has found some of the best evidence yet that water flowed on the Red Planet's surface long ago, researchers announced Wed., Dec. 7. The Opportunity rover, which landed on Mars nearly eight years ago, has discovered a thin, bright mineral vein along the rim of a huge crater called Endeavour.
