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.

Terrestrial cosmogenic-nuclide production systematics calculated from numerical simulations
Jozef Masarik,Robert C. Reedy +1 more
TL;DR: In this article, the production of cosmogenic nuclides in the Earth's atmospheric and in-situ in the surface is discussed and the production rates of 3 H, 7 Be, 10 Be, 14 C, 21 Ne, 26 Al, and 36 Cl agree well with experimental measurements for certain minerals in surface samples.
Journal ArticleDOI

TL;DR: Analysis of data from the Dawn spacecraft implies that asteroid Vesta is rich in volatiles, and models of Vesta’s evolution based on studies of howardite, eucrite, and diogenite meteorites are tested, finding that global Fe/O and Fe/Si ratios are consistent with HED compositions.
Journal ArticleDOI
Dawn’s Gamma Ray and Neutron Detector

TL;DR: The Gamma Ray and Neutron Detector (GRaND) was used in the NASA Dawn mission to map the surface elemental composition of Vesta and Ceres at regional spatial scales as mentioned in this paper, including the constituents of silicate and oxide minerals, ices, and products of volcanic exhalation and aqueous alteration.
