    • Closeup Of Asteroid Vesta

      By
      AVIATION WEEK
      Vesta is seen from 3,200 mi. by NASA's Dawn spacecraft at a point 115 million mi. from Earth. The south pole (lower right) is the center of a 300-mi.-dia. basin, perhaps from a huge impact that nearly destroyed Vesta, leaving signatures such as troughs near the equator (lower left) and mountains that may be among the tallest in the solar system. A triplet of craters is nicknamed the Snowman. Bright and dark areas are visible, including some in craters (above center). Credit: Marc D. Rayman Jet Propulsion Laboratory, Pasadena, Calif.
