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 a survivor from the earliest times of rocky body formation. Observations from orbit show that Vesta is the parent body of the Howardite, Eucrite, Diogenite meteorites. Vesta has an iron core and a eucritic–diogenitic crust. Its surface is characterized by abundant impact craters but with no evident… Expand
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
The primordial collisional history of Vesta: crater saturation, surface evolution and survival of the basaltic crust
Abstract The Dawn mission recently visited the asteroid 4 Vesta and the observations performed by the spacecraft revealed more pieces of the intriguing mosaic of its history. Among the first resultsExpand
Composition of the northern regions of Vesta analyzed by the Dawn mission
Abstract The surface composition of the northern regions of Vesta, observed by the Dawn spacecraft, offers the possibility to test several hypotheses related to impact-related processes. We usedExpand
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
Is Vesta an intact and pristine protoplanet
Abstract It is difficult to find a Vesta model of iron core, pyroxene and olivine-rich mantle, and HED crust that can match the joint constraints of (a) Vesta’s density and core size as reported byExpand
The late accretion and erosion of Vesta’s crust recorded by eucrites and diogenites as an astrochemical window into the formation of Jupiter and the early evolution of the Solar System
Abstract The circumsolar disc was the birthplace of both planetesimals and giant planets, yet the details of their formation histories are as elusive as they are important to understand the originsExpand
Detections and geologic context of local enrichments in olivine on Vesta with VIR/Dawn data
The magmatism characterizing the early history of the asteroid Vesta has long been investigated with the mafic and ultramafic meteorites howardite, eucrite, and diogenite (HED). The lack of geologicExpand
The Formation of Jupiter, the Jovian Early Bombardment and the Delivery of Water to the Asteroid Belt: The Case of (4) Vesta
TLDR
It is argued that the observational data are best reproduced if the bulk of the impactors was represented by 1–2 km wide planetesimals and if Jupiter underwent a limited (a fraction of au) displacement. Expand
Olivine on Vesta as exogenous contaminants brought by impacts: Constraints from modeling Vesta's collisional history and from impact simulations
The survival of asteroid Vesta during the violent early history of the Solar System is a pivotal constraint on theories of planetary formation. Particularly important from this perspective is theExpand
Differentiation of Vesta: Implications for a shallow magma ocean
Abstract The Dawn mission confirms earlier predictions that the asteroid 4 Vesta is differentiated with an iron-rich core, a silicate mantle and a basaltic crust, and supports the conjecture of VestaExpand

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 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. 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
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
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
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
Elemental Mapping by Dawn Reveals Exogenic H in Vesta’s Regolith
TLDR
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. Expand
