P42A:
Vesta and Ceres as Seen by Dawn and Earth-Based Instruments I


Session ID#: 10401

Session Description:
Ceres and Vesta are the largest bodies in the main asteroid belt. Unlocking their geological histories will advance our understanding of how proto-planets form and evolve. This session is focused on Dawn mission data and its three onboard instruments: two framing cameras (FC), the visible and IR spectrometer (VIR), and the gamma-ray and neutron spectrometer (GRaND). First results from Ceres based on approach, survey, and high-altitude mapping campaigns constitute the highlights of this session supplemented by thorough investigations on Vesta geology. Complementary Earth-based (ground and orbital) observations along with laboratory, numerical, and theoretical applications and analyses are particular welcome.
