Caption: Bouguer gravity map of Mars. Animation of a rotating Mars globe showing a Bouguer gravity map. A free-air gravity map was created by studying small variations in the orbits of Mars Global Surveyor, Mars Odyssey, and Mars Reconnaissance Orbiter spacecraft. The Bouguer gravity map subtracts the gravitational effects of the uneven Martian surface, revealing the gravity anomalies caused by underlying material. These gravity anomalies can be explained by variations in the thickness of the Martian crust. Local increases in gravity (reds and whites) indicate places where the crust is thinner and the denser mantle is closer to the surface.
