This July 24, 2011 image of the Asteroid Vesta, released by NASA/JPL, was captured by the Dawn spacecraft at a distance of 3,200 miles (5,200 kilometers). Dawn entered orbit around Vesta on July 15, 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. (AP Photo/ NASA/JPL)
