New Surface Composition Maps of Mercury Provide Clues to the Planet’s History

Using data from the MESSENGER spacecraft, scientists reveal previously unrecognized geochemical terranes of Mercury. Washington, D.C. – 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 […]
