Sen— This image of Cornelia Crater on the giant asteroid Vesta was taken by NASA's Dawn mission from about 420 miles (680 kilometres) above the surface during a high-altitude mapping orbit. The dark material that speckles the surface of the asteroid is helping scientists to understand the impact environment early in Vesta's evolution. Scientists under the lead of the Max Planck Institute for Solar System Research (MPS) in Germany have shown that impacting small asteroids delivered dark, carbonaceous material to the protoplanet.
