The analysis of six landing sites that were candidates for the two NASA Mars Exploration Rovers (MER) benefited from recently available image data from the Thermal Emission Imaging Spectrometer (THEMIS) onboard the 2001 Mars Odyssey spacecraft. The c

The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and MiniâThermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coa

[1] This study presents the first global compositional maps of plagioclase, the most abundant mineral in the Martian crust. Linear deconvolutions of spectra from the Thermal Emission Spectrometer (TES) allowed calculation of average plagioclase compo

During 2015, a unique launch opportunity exists that allows for a New-Frontiers-class mission to discover a compositional gradient of small bodies in our solar system. The proposed seven year mission includes a flyby of main belt asteroid (108144) 20

[1] The compositions of plagioclase, the most abundant mineral in the Martian crust, reflect changing conditions during magmatic evolution. Plagioclase contains spectral features at thermal infrared wavelengths that permit its detection by thermal em

[1] Morphologic, morphometric, and thermophysical aspects of domical structures in a restricted part of the Mars northern plains were characterized using Mars Odyssey and Mars Global Surveyor data. The majority of domical structures consist of relati

[1] Four definitive and three probable rayed craters have been identified on Mars using 100-m resolution thermal infrared images obtained by the Mars Odyssey Thermal Emission Imaging System (THEMIS). These seven craters are similar to the previously
