Scientific paper

The Dawn mission will rendezvous with asteroid (4) Vesta in July 2011. We have developed criteria for classifying terrains on Vesta by using the Dawn Framing Camera (FC) spectral bands and laboratory spectra of meteorites that are related to Vesta. Howardite-Eucrite-Diogenite (HEDs) meteorites and, for example, pallasites, and mesosiderites are likely representative for the composition of these terrains. We implemented the classification of terrains in a program called DawnKey, which allows ingesting Dawn FC color cubes consisting of 7 filters. The software then returns the meteorite type that best fit the spectrum for each pixel.
