Data Return:
  • Images of Vesta and Ceres in three colors and black and white
  • Full surface with mapping spectrometer in three bands, 0.35 to 0.9 micron, 0.8 to 2.5 micron and 2.4 to
    5.0 micron
  • Neutron and gamma ray spectra to produce maps of the surface elemental composition of each asteroid, including the abundance of major rock-forming elements (O, Mg, Al, Si, Ca, Ti, and Fe), trace elements (Gd and Sm), long-lived radioactive elements (K, Th, and U), and light elements such as H, C, and N, which are the major constituents of ices.
  • Radio tracking to determine mass, gravity field, principal axes, rotational axis and moments of inertia.
