A Global View of Martian Surface Compositions from MGS-TES
Thermal Emission Spectrometer (TES) data from the Mars Global Surveyor (MGS) are used to determine compositions and distributions of martian low-albedo regions. Two surface spectral signatures areExpand
Global mineral distributions on Mars
[1] Determining the mineralogy of Mars is an essential part of revealing the conditions of the surface and subsurface. A deconvolution method was used to remove atmospheric components and determineExpand
A thermal emission spectral library of rock-forming minerals
A library of thermal infrared spectra of silicate, carbonate, sulfate, phosphate, halide, and oxide minerals has been prepared for comparison to spectra obtained from planetary and Earth-orbitingExpand
Mars Global Surveyor Thermal Emission Spectrometer experiment: Investigation description and surface science results
The Thermal Emission Spectrometer (TES) investigation on Mars Global Surveyor (MGS) is aimed at determining (1) the composition of surface minerals, rocks, and ices; (2) the temperature and dynamicsExpand
Global mapping of Martian hematite mineral deposits: Remnants of water‐driven processes on early Mars
Near-global (60°S to 60°N) thermal infrared mapping by the Thermal Emission Spectrometer (TES) on Mars Global Surveyor has revealed unique deposits of crystalline gray hematite (α-Fe2O3) exposed atExpand
Identification of a basaltic component on the Martian surface from Thermal Emission Spectrometer data
The Mars Global Surveyor Thermal Emission Spectrometer (TES) instrument collected 4.8×106 spectra of Mars during the initial aerobraking and science-phasing periods of the mission (September 14,Expand
Chloride-Bearing Materials in the Southern Highlands of Mars
The identification of chlorides in the ancient southern highlands suggests that near-surface water was available and widespread in early Martian history. Expand
Spectroscopic Identification of Carbonate Minerals in the Martian Dust
Thermal infrared spectra of the martian surface indicate the presence of small concentrations of carbonates, specifically dominated by magnesite (MgCO3), which may have been an important sink for a thicker carbon dioxide atmosphere in the martians past. Expand
Discovery of Olivine in the Nili Fossae Region of Mars
We have detected a 30,000-square-kilometer area rich in olivine in the Nili Fossae region of Mars. Nili Fossae has been interpreted as a complex of grabens and fractures related to the formation ofExpand
Spectral data set factor analysis and end-member recovery: Application to analysis of Martian atmospheric particulates
A method is described that uses target transformation factor analysis techniques to determine the number of independently variable components and recover the spectral end-members present in a set ofExpand
