Ruby-forming mineral found by Mars rover hints at violent impacts
So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across the Martian surface seem to hint at a different geological history—carrying t...
