This is an early mineral map derived from the different reflected light, or spectral, signatures, measured by NASA’s Moon Mineralogy Mapper on board the Indian Space Research Organization’s Chandrayaan-1 spacecraft. The green, purple and blue areas are covered with iron-rich lava flows. These are similar to the lava flows of Hawaii. The red and pink regions contain the mineral plagioclase. Plagioclase is one of the minerals found in granite rocks on Earth, such as the granite of Yosemite National Park.
