(PhysOrg.com) -- Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side.
The large structure near the south pole that showed up so prominently in previous images is visible in the center of the illuminated surface. Compared to other images, this one shows more of the surface beneath the spacecraft in the shadow of night. Vesta turns on its axis once every five hours and 20 minutes.
Dawn entered orbit around Vesta on July 15, 2011, and will spend a year orbiting the body. After that, the next stop on its itinerary will be an encounter with the dwarf planet Ceres.
