Today, NASA scientists presented findings that prove water once ran across the surface of Mars. Though the rocks have yet to be analyzed, scientists say the photographs clearly indicate that these rock formations were smoothed and shaped by water. The next step, says NASA, will be drilling into the rock for evidence of carbon deposits. — rachel
