These two maps of the giant asteroid Vesta show patterns of brightness from NASA's Hubble Space Telescope (top) and NASA's Dawn spacecraft (bottom). Hubble's view is from an orbit around Earth. Dawn went into orbit around Vesta from 2011 to 2012. Scientists have been able to correlate several bright and dark features originally identified in Hubble images with features imaged at high resolution by the Dawn spacecraft's framing camera.
