This map depicts the crustal thickness of the near side of the moon. It was derived using gravity data from NASA's GRAIL mission and topography data from NASA's Lunar Reconnaissance Orbiter. The measurements match those found via seismic data at the NASA Apollo mission 12 and 14 landing sites, where crustal thickness is 19 miles (30 kilometers). The average thickness of the crust is 21 miles (34 kilometers), which is almost 12 miles (20 kilometers) thinner than values from previous studies. Regions of crustal thinning in blue are associated with several large impact basins several hundreds of kilometer in diameter.
