A spacecraft flyby of an asteroid reveals a high-density body that is more like a planetesimal than a rubble pile. The Visible, InfraRed, and Thermal Imaging Spectrometer (VIRTIS) on Rosetta obtained hyperspectral images, spectral reflectance maps, and temperature maps of the asteroid 21 Lutetia. No absorption features, of either silicates or hydrated minerals, have been detected across the observed area in the spectral range from 0.4 to 3.5 micrometers. The surface temperature reaches a… Expand
Images of Asteroid 21 Lutetia: A Remnant Planetesimal from the Early Solar System
TLDR
A spacecraft flyby of an asteroid reveals a high-density body that is more like a planetesimal than a rubble pile, which contrasts with smaller asteroids visited by previous spacecraft, which are probably shattered bodies, fragments of larger parents, or reaccumulated rubble piles. Expand
THE ONSET OF DIFFERENTIATION AND INTERNAL EVOLUTION: THE CASE OF 21 LUTETIA
TLDR
A numerical code is developed, used for studying the geophysical history of Vesta, to explore several scenarios of internal evolution of Lutetia, which differ in the strength of their radiogenic sources and in their global post-sintering porosity. Expand
Global spectrophotometric properties of Asteroid (21) Lutetia using Rosetta-OSIRIS images
Abstract We present a spectrophotometric analysis of the surface areas of asteroid (21) Lutetia that were imaged during the Rosetta flyby on July 2010 by the OSIRIS camera in the wavelength range 269Expand
Overview of Lutetia's surface composition
Abstract All available data regarding compositionally diagnostic measurements of asteroid (21) Lutetia are assembled. We review ground-based observations together with recent spacecraft missionExpand
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
A plausible link between the asteroid 21 Lutetia and CH carbonaceous chondrites
A crucial topic in planetology research is establishing links between primitive meteorites and their parent asteroids. In this study we investigate the feasibility of a connection between asteroidsExpand
Observations, Meteorites, and Models: A Preflight Assessment of the Composition and Formation of (16) Psyche
TLDR
Observations of Psyche with data from meteorites and models for planetesimal formation are combined to produce the best current hypotheses for Psyche's properties and provenance. Expand
The thermo-chemical evolution of asteroid 21 Lutetia
In the present study, we model the thermo-chemical evolution of Asteroid 21 Lutetia using new data obtained by the Rosetta flyby in July 2010. We investigate the dependence of the evolution on theExpand
Reconciling main belt asteroid spectral flux density measurements with a self-consistent thermophysical model
Abstract Thermophysical models consistent with Earth’s Moon and infrared and submillimeter measurements obtained during the Rosetta fly-by of Asteroid (21) Lutetia have been applied to computationsExpand
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
