PS4.2Vesta science and exploration by Dawn
|Convener: H. Hiesinger|
4Vesta is known to have a magmatic pyroxene-bearing crust, and thought to be the parent body of the HED class of meteorites. In July 2011 the Dawn spacecraft arrived at this asteroid, which is the second largest known body in the asteroid belt. Equipped with a framing camera (FC), a visible and IR spectrometer (VIR) and a gamma-ray and neutron spectrometer (GRaND), Dawn explores Vesta at unprecedented detail to characterize the conditions and processes of the solar system's earliest epoch by investigating one of the largest protoplanets remaining intact since its formations. This session will focus on the results of the Dawn mission, but contributions are welcome concerning complementary studies of Vesta, such as modeling, theory, 1AU remote sensing, or the study of HED meteorites.
