The Thermal Emission Imaging System (THEMIS) on Mars Odyssey has produced infrared to visible wavelength images of the martian surface that show lithologically distinct layers with variable thickness, implying temporal changes in the processes or environments during or after their formation. Kilometer-scale exposures of bedrockare observed; elsewhere airfall dust completely mantles the surface over thousands of square kilometers. Mars has compositional variations at 100-meter scales, for… 
Evidence for extensive, olivine-rich bedrock on Mars
Color infrared observations of an area around the Nili Fossae acquired by the Mars Odyssey thermal emission imaging system have been used to map the regional distribution and geologic context of
New Views of the Martian Polar Regions: The Latest Results from the Mars Odyssey THEMIS Investigation
One of the many questions of Martian exploration is to uncover the history of Mars, through analysis of the polar layered deposits (PLD). Martian polar ice caps hold most of the exposed water ice on
Global distribution of bedrock exposures on Mars using THEMIS high‐resolution thermal inertia
[1] We investigate high thermal inertia surfaces using the Mars Odyssey Thermal Emission Imaging System (THEMIS) nighttime temperature images (100 m/pixel spatial sampling). For this study, we
Evidence for magmatic evolution and diversity on Mars from infrared observations
Observations show that the martian crust, while dominated by basalt, contains a diversity of igneous materials whose range in composition from picritic basalts to granitoids rivals that found on the Earth.
Survey of TES high albedo events in Mars' northern polar craters
Following the work exploring Korolev Crater (Armstrong et al., 2005) for evidence of crater interior ice deposits, we have conducted a survey of Thermal Emission Spectroscopy (TES) temperature and
Analysis of Properties of the North and South Polar Layered Deposits
One of the many questions of Martian exploration is to uncover the history of Mars, through analysis of the polar layered deposits (PLD). Martian polar ice caps hold most of the exposed water ice on
Pretty Green Mineral--Pretty Dry Mars?
Spectra of the Martian surface from the Mars Global Surveyor Thermal Emission Spectrometer (TES) have been matched with laboratory spectra of olivine. Todd Hoefen and Roger Clark (U. S. Geological


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 are
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,
Thermal and albedo mapping of Mars during the Viking primary mission
Measurements of Martian emission and reflection reveal wide variations of surface properties and indicate the presence of a larger atmospheric contribution to the observed radiances than was
Exposed Water Ice Discovered near the South Pole of Mars
The Mars Odyssey Thermal Emission Imaging System (THEMIS) has discovered water ice exposed near the edge of Mars' southern perennial polar cap, indicating that surface H2O ice may be widespread around and under the perennial CO2 cap.
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 at
"White Rock": an eroded Martian lacustrine deposit(?)
The existence and location of ancient lake sites and sediments have important implications for Martian paleoclimate and exobiology. White Rock, an enigmatic crater interior deposit, may be the eroded

Mars Global Surveyor Mars Orbiter Camera: Interplanetary cruise through primary mission
More than 3 years of high-resolution (1.5–20 m/pixel) photographic observations of the surface of Mars have dramatically changed our view of that planet. Among the most important observations and
Sedimentary rocks of early Mars.
Affinity for impact craters suggests dominance of lacustrine deposition; alternatively, the materials were deposited in a dry, subaerial setting in which atmospheric density, and variations thereof mimic a subaqueous depositional environment.
Mineralogic and compositional properties of Martian soil and dust: Results from Mars Pathfinder
Mars Pathfinder obtained multispectral, elemental, magnetic, and physical measurements of soil and dust at the Sagan Memorial Station during the course of its 83 sol mission. We describe initial
