This composite image is a simulated true color image of part of asteroid Vesta's northern region, which contains the 'snowman craters.' Images such as these greatly help the process of understanding Vesta's geological history.

NASA's Dawn spacecraft used its Visible and Infrared Imaging Spectrometer instrument to produce these three different composite images of the same region of asteroid Vesta's surface.
