High spectral resolution reflectance spectroscopy of minerals
The reflectance spectra of minerals are studied as a function of spectral resolution in the range from 0.2 to 3.0 {mu}m. Selected absorption bands were studied at resolving powers…
Reflectance spectroscopy - Quantitative analysis techniques for remote sensing applications. [in planetary surface geology]
Several methods for the analysis of remotely sensed reflectance data are compared, including empirical methods and scattering theories, both of which are important for solving remote sensing…
Imaging spectroscopy: Earth and planetary remote sensing with the USGS Tetracorder and expert systems
[1] Imaging spectroscopy is a tool that can be used to spectrally identify and spatially map materials based on their specific chemical bonds. Spectroscopic analysis requires significantly more…
Detection of Adsorbed Water and Hydroxyl on the Moon

Space-based spectroscopic measurements provide evidence for water or hydroxyl (OH) on the surface of the Moon and imply that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.
Character and Spatial Distribution of OH/H2O on the Surface of the Moon Seen by M3 on Chandrayaan-1

Analysis of recent infrared mapping by Chandrayaan-1 and Deep Impact, and reexamining Cassini data obtained during its early flyby of the Moon, Pieters et al. reveal a noticeable absorption signal for H2O and OH across much of the surface, implying that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.
Identification of hydrated silicate minerals on Mars using MRO‐CRISM: Geologic context near Nili Fossae and implications for aqueous alteration

The Noachian terrain west of the Isidis basin hosts a diverse collection of alteration minerals in rocks comprising varied geomorphic units within a 100,000 km2 region in and near the Nili Fossae.…
Orbital Identification of Carbonate-Bearing Rocks on Mars

- 19 December 2008
The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.
Identification of a basaltic component on the Martian surface from Thermal Emission Spectrometer data
