Vesta Topography and Gravity Maps

Minesex: This video from NASA's Dawn mission shows that the gravity field of Vesta closely matches the surface topography of the giant asteroid Vesta. The video shows shaded topography from Dawn's framing camera on the left, with troughs and craters visible, and color-contoured data from Dawn's gravity experiment on the right. Red shows the areas with a higher than average gravity field and blue-purple shows the areas
where the field is weaker on average. The highest topography, on the rim of the Rheasilvia basindeep in the southern hemisphere, shows a particularly strong gravity field. The dashed line indicates the north-south axis. The topography model is derived from framing camera images from Dawn's high-altitude mapping orbit (420 miles or 680 kilometers above the surface), and the gravity data come from the low-altitude mapping orbit (130 miles or 210 kilometers above the surface). Vesta takes approximately 5.34 hours to make a rotation.,Source: Minesex
