	Scientific imaging system of the Dawn Mission to the two complementary protoplanets, 1 Ceres and 4 Vesta. MPS + Framing Camera    Gallery + Lecture on    Framing    Camera		Accomplishes the Dawn mission's scientific and measurement objectives of producing spectral images INAF + NEW!! VIR    Interactive + VIR Gallery		Measures elemental abundances on the surface of Vesta and Ceres LANL + NEW!! GRaND    Interactive  + GRaND Gallery		Allows accurate measurements of the spacecraft's orbit from which scientists can determine the gravity fields of Vesta and Ceres Orbital

• 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.
