Vesta to the Core Vesta is one of the largest bodies in the main asteroid belt. Unlike most other asteroids, which are fragments of once larger bodies, Vesta is thought to have survived as a protoplanet since its formation at the beginning of the solar system (see the Perspective by Binzel, published online 20 September). Based on data obtained with the Gamma Ray and Neutron Detector aboard the Dawn spacecraft, Prettyman et al. (p. 242, published online 20 September) show that Vesta's reputed… Expand

Pitted Terrain on Vesta and Implications for the Presence of Volatiles
TLDR
Analysis of data from the Dawn spacecraft implies that asteroid Vesta is rich in volatiles, suggesting that impactor materials are preserved locally in relatively high abundance on Vesta and thatimpactor composition has played an important role in shaping the asteroid’s geology. Expand
Exploring exogenic sources for the olivine on Asteroid (4) Vesta
Abstract The detection of olivine on Vesta is interesting because it may provide critical insights into planetary differentiation early in our Solar System’s history. Ground-based and Hubble SpaceExpand
Asteroid (4) Vesta II: Exploring a geologically and geochemically complex world with the Dawn Mission
Abstract More than 200 years after its discovery, asteroid (4) Vesta is thought to be the parent body for the howardite, eucrite and diogenite (HED) meteorites. The Dawn spacecraft spent ∼14 monthsExpand
Vesta's mineralogical composition as revealed by the visible and infrared spectrometer on Dawn
The Dawn spacecraft mission has provided extensive new and detailed data on Vesta that confirm and strengthen the Vesta-howardite-eucrite-diogenite (HED) meteorite link and the concept that Vesta isExpand
The composition of Vesta from the Dawn mission
Abstract Vesta’s surface composition has been of special interest since early, disk-integrated telescopic spectral observations indicated that it is basaltic, differentiated and similar to the HEDExpand
Dawn completes its mission at 4 Vesta
The Dawn mission was designed to test our hypothesis about the origin and evolution of the early solar system by visiting the largest differentiated basaltic asteroid, 4 Vesta, believed to be aExpand
Delivery of dark material to Vesta via carbonaceous chondritic impacts
NASA’s Dawn spacecraft observations of Asteroid (4) Vesta reveal a surface with the highest albedo and color variation of any asteroid we have observed so far. Terrains rich in low albedo darkExpand
Detection of new olivine-rich locations on Vesta
Abstract The discovery of olivine on Vesta’s surface by the VIR imaging spectrometer onboard the Dawn space mission has forced us to reconsider our views of Vestan petrogenetic models. Olivines wereExpand
The structure of the asteroid 4 Vesta as revealed by models of planet-scale collisions
TLDR
Three-dimensional simulations of Vesta’s global evolution under two overlapping planet-scale collisions closely reproduce its observed shape, and provide maps of impact excavation and ejecta deposition. Expand
Vestan lithologies mapped by the visual and infrared spectrometer on Dawn
We present global lithological maps of the Vestan surface based on Dawn mission's Visible InfraRed (VIR) Spectrometer acquisitions with a spatial sampling of 200 m. The maps confirm the resultsExpand

Spectroscopic Characterization of Mineralogy and Its Diversity Across Vesta
TLDR
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. Expand
Color and Albedo Heterogeneity of Vesta from Dawn
TLDR
Dawn's observations confirm that Vesta is a small differentiated planetary body with an inner core, and represents a surviving proto-planet from the earliest epoch of solar system formation, and reveal its color and photometric diversity are indicative of its status as a preserved, differentiated protoplanet. Expand
Dawn at Vesta: Testing the Protoplanetary Paradigm
TLDR
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. Expand
The Violent Collisional History of Asteroid 4 Vesta
TLDR
Dawn observations confirm that Vesta is a small differentiated planetary body with an inner core, and represents a surviving proto-planet from the earliest epoch of solar system formation, and presents the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle. Expand
The Geologically Recent Giant Impact Basins at Vesta’s South Pole
TLDR
Dawn’s global mapping of Vesta reveals that its observed south polar depression is composed of two overlapping giant impact features, which provide exceptional windows into impact processes at planetary scales, and spacecraft data provide a detailed characterization of the second most massive asteroid in the solar system.

Geochemistry of 4 Vesta based on HED meteorites: Prospective study for interpretation of gamma ray and neutron spectra for the Dawn mission
Asteroid 4 Vesta, believed to be the parent body of the howardite, eucrite, and diogenite (HED) meteorites, will be investigated by the Dawn orbiting spacecraft. Dawn carries a gamma ray and neutronExpand
Vesta’s Shape and Morphology
TLDR
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. Expand
Mega-ejecta on asteroid Vesta

"Solar-Wind-Rich" Howardite: True Regolith vs. CM-Implanted Components
Howardite, eucrite and diogenite meteorites (collectively HED) likely originate from asteroid 4-Vesta [1], one of two asteroids targeted by NASA’s Dawn mission. Many ho-wardites (polymict breccias ofExpand
HED Meteorites and Their Relationship to the Geology of Vesta and the Dawn Mission
Howardite-eucrite-diogenite (HED) meteorites, thought to be derived from 4 Vesta, provide the best sampling available for any differentiated asteroid. However, deviations in oxygen isotopicExpand
