Description	English: This image depicting the porosity of the lunar highland crust was derived using bulk density data from NASA's GRAIL mission and independent grain density measurements from NASA's Apollo moon mission samples as well as orbital remote-sensing data. Red corresponds to higher than average porosities and blue corresponds to lower than average porosities. White denotes regions that contain mare basalts (thin lines) and that were not analyzed. The 12 percent average porosity of the highland crust is a consequence of fractures generated by billions of years of impact cratering. The crustal porosities in the interiors of many impact basins are lower than their surroundings, a result of high temperatures experienced at the time of crater formation. In contrast, the porosities immediately exterior to many impact basins are higher than average as a result of fracturing by impact-generated shock waves and the deposition of impact ejecta.
