Global mosaic of Vesta (created from images taken from DAWN)
density and homogeneity of two complementaryprotoplanets, 1 Ceres and 4 Vesta, one wet and one dry
Determine shape, size, composition and mass
Study surface morphology, cratering
Determine thermal history and size of core
Understand role of water in controlling asteroid evolution
Test the current paradigm of Vesta as the howardite, eucrite, and diogenite (HED) parent body
Study which, if any, meteorites come from Ceres
Provide a geologic context for HEDs
Dawn uses a solar ion propulsion system for its interplanetary journey. It has arrived at Vesta on Jul 2011 and orbited the body for one year. Presently it is en route to Ceres, where it is expected to arrive by Feb. 2015.
The DLR Institute of Planetary Research has contributed to developing and building, under the leadership of the Max Planck Institute, Lindau, the two Framing Cameras onboard the Dawn Mission. The Asteroids and Comets Section is also represented in the Dawn Science Team by a Co-Investigator.
