                        Gamma-Ray Readings from Eros

          This chart shows the gamma-ray spectrum from the surface
          of Eros. These scientific data -- the first ever
          collected on the surface of an asteroid -- result from 7
          days of measurements following NEAR Shoemaker's historic
          landing on February 12.

          The gamma-ray instrument has two detectors -- marked
          above by the red and blue traces -- which picked up
          clear signatures of key elements in the composition of
          Eros. These data, which surpass in quality all the data
          accumulated by this instrument from orbit, will help
          NEAR scientists relate the composition of Eros to that
          of meteorites that fall to Earth.
          Built and managed by The Johns Hopkins University
          Applied Physics Laboratory, Laurel, Maryland,
          NEAR-Shoemaker was the first spacecraft launched in
          NASA's Discovery Program of low-cost, small-scale
          planetary missions. See the NEAR web site for more
          details (http://near.jhuapl.edu) .
