Curiosity may have spent a while limbering up for the mission ahead, but now it's found evidence of an ancient streambed on Mars that once had "vigorous" water flow. Photos of two rock outcroppings taken by the rover's mast camera between the north rim of Gale Crater and the foot of Mount Sharp reveal gravel embedded into a layer of conglomerate rock. The shape of the small stones indicate to NASA JPL scientists that they were previously moved, and their size (think from grains of sand to golf balls) are a telltale sign that water did the work instead of wind. Evidence of H2O on Mars has been spotted before, but this is the first direct look at the composition of riverbeds NASA has observed from above.
