Image display for discovery #2

GLOBAL MINERAL MAPS produced from TES data gave the first detailed picture of Mars' mineralogical diversity. This image, one of many, maps the locations of high-calcium pyroxene, an igneous mineral indicating the presence of basalt. Additional mineral maps are available from the TES ASU Data Archive.
