New Mercury surface composition maps illuminate the planet's history
Washington DC (SPX) Mar 17, 2015 - Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury's surface chemistry that reveal previously unrecognized geochemical terranes - large regions that have compositions distinct from their surroundings. The presence of these large terranes has important implications for the history of the planet. The MESSENGER mission was designed to answer severa ... more
