Global Mineralogical and Aqueous Mars History Derived from OMEGA/Mars Express Data
Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new…
Dawn at Vesta: Testing the Protoplanetary Paradigm
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.
The Cassini Visual And Infrared Mapping Spectrometer (Vims) Investigation
The Cassini visual and infrared mapping spectrometer (VIMS) investigation is a multidisciplinary study of the Saturnian system. Visual and near-infrared imaging spectroscopy and high-speed…

The Surface Composition and Temperature of Asteroid 21 Lutetia As Observed by Rosetta/VIRTIS
Lutetia is likely a remnant of the primordial planetesimal population, unaltered by differentiation processes and composed of chondritic materials of enstatitic or carbonaceous origin, dominated by iron-poor minerals that have not suffered aqueous alteration.
VIRTIS: The imaging spectrometer of the Rosetta mission
Composition and Physical Properties of Enceladus' Surface
Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys in 2005, and upper limits of 140 kelvin are derived for the temperatures in the tiger stripes.
Dawn Mission to Vesta and Ceres
The initial exploration of any planetary object requires a careful mission design guided by our knowledge of that object as gained by terrestrial observers. This process is very evident in the…
Surface composition and temperature of the TNO Orcus
Aims. The aim of this paper is to investigate the surface composition of the Transneptunian Object (TNO) Orcus. Methods. High quality observations have been carried out with the new instrument…
The organic-rich surface of comet 67P/Churyumov-Gerasimenko as seen by VIRTIS/Rosetta
The VIRTIS instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of the comet 67P/Churyumov-Gerasimenko, and no ice-rich patches are observed, indicating a generally dehydrated nature for the surface currently illuminated by the Sun.
