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…
Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on Mars Reconnaissance Orbiter (MRO)
 The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a hyperspectral imager on the Mars Reconnaissance Orbiter (MRO) spacecraft. CRISM consists of three subassemblies, a gimbaled…
Sulfates in Martian Layered Terrains: The OMEGA/Mars Express View
Outcrops in Valles Marineris, Margaritifer Sinus, and Terra Meridiani show evidence for kieserite, gypsum, and polyhydrated sulfates, which constitute direct records of the past aqueous activity on Mars.
Mars Surface Diversity as Revealed by the OMEGA/Mars Express Observations
The OMEGA investigation, on board the European Space Agency Mars Express mission, has identified and mapped mafic iron-bearing silicates of both the northern and southern crust, localized concentrations of hydrated phyllosilicates and sulfates but no carbonates, and ices and frosts with a water-ice composition of the north polar perennial cap.
Phyllosilicates on Mars and implications for early martian climate
It is inferred that the two main families of hydrated alteration products detected—phyllosilicates and sulphates—result from different formation processes, which occurred during two distinct climatic episodes: an early Noachian Mars, resulting in the formation of Hydrated silicates, followed by a more acidic environment, in which sulphates formed.
Subsurface water and clay mineral formation during the early history of Mars
Clay minerals, recently discovered to be widespread in Mars’s Noachian terrains, indicate long-duration interaction between water and rock over 3.7 billion years ago, and available data indicate substantial Martian clay formation by hydrothermal groundwater circulation and a Noachia rock record dominated by evidence of subsurface waters.
Sulfates in the North Polar Region of Mars Detected by OMEGA/Mars Express
The observations of the northern circumpolar regions of Mars reveal that water alteration played a major role in the formation of the constituting minerals of northerncircumpolar terrains.
A synthesis of Martian aqueous mineralogy after 1 Mars year of observations from the Mars Reconnaissance Orbiter
Martian aqueous mineral deposits have been examined and characterized using data acquired during Mars Reconnaissance Orbiter's (MRO) primary science phase, including Compact Reconnaissance Imaging…
Hydrated silicate minerals on Mars observed by the Mars Reconnaissance Orbiter CRISM instrument
The diversity of phyllosilicate mineralogy is expanded with the identification of kaolinite, chlorite and illite or muscovite, and a new class of hydrated silicate (hydrated silica).
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…
