Ever wonder exactly what sort of rocks litter the Moon’s surface in countless bright and dark blotches? Check out the U.S. Geological Survey’s new Moon map covering the entire surface of Earth’s satellite in extraordinary detail. The Unified Geologic Map of the Moon will “serve as the definitive blueprint of the Moon’s surface geology for future human missions and will be invaluable for the international scientific community, educators and the public at large,” says the USGS. The new map is based on images and data from six Apollo regional maps and observations from more recent missions, including laser altimetry for the north and south polar regions, provided by the Lunar Orbiter, and stereo observations of equatorial areas by Japan’s SELENE spacecraft. Researchers developed a unified description of the moon’s stratigraphy and resolved inconsistencies in earlier maps.
NASA’s Dawn spacecraft, cruising in its lowest and final orbit at dwarf planet Ceres, has delivered the first images from its best-ever viewpoint. The new images showcase details of the cratered and fractured surface. Dawn is now approximately 240 miles (385 kilometres) above Ceres, which is where it will remain for the rest of its mission.
