A high-resolution free-air gravity map based on GRAIL data, overlaid on terrain based on LRO altimeter (LOLA) and camera (LROC) data. The view is south-up, with the south pole near the horizon in the upper left and the crescent Earth in the distance. The terminator crosses the eastern rim of the Schrödinger basin. Gravity is painted onto the areas that are in or near the night side. Red corresponds to mass excesses and blue to mass deficits. Credit: NASA
