Science Payload/Data Return

 
Science Payload:

Framing Camera : German Aerospace Center, DLR, Institute of Space Sensor Technology and Planetary Exploration, Berlin.

Mapping Spectrometer : The Institute for Astrophysics in Space (IAFS), Rome

Gamma Ray and Neutron Spectrometer : Los Alamos National Laboratory, Los Alamos NM


Data Return:


  • Full surface imagery of Vesta and Ceres images in seven colors at Vesta and in three at Ceres
  • 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.
