TL;DR: Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs, and present the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle.

TL;DR: The mineralogy of Vesta, based on data obtained by the Dawn spacecraft’s visible and infrared spectrometer, is consistent with howardite-eucrite-diogenite meteorites, which suggests a complex magmatic evolution that led to a differentiated crust and mantle.

TL;DR: The Framing Camera (FC) as discussed by the authors is the German contribution to the Dawn mission, which will map 4 Vesta and 1 Ceres through a clear filter and 7 band-pass filters covering the wavelengths from the visible to the near-IR.

TL;DR: Dawn observations confirm the large impact basin at Vesta's south pole and reveal evidence for an earlier, underlying large basin (Veneneia), underscoring Vesta’s unique role as a transitional solar system body.

TL;DR: C Ceres’ dry exterior displays hydroxylated silicates, including ammoniated clays of endogenous origin, which suggest a mechanically strong lithosphere with a weaker deep interior.
