Reflectance spectra of "featureless" materials and the surface mineralogies of M- and E-class asteroids
(Journal of Geophysical Research, 1990-01-10)The 0.3- to 2.6-μm reflectance spectra of meteoritic enstatite (nearly pure MgSiO3), iron meteorite metal, magnetite and amorphous carbon, and various mixtures of these materials with mafic silicates have been measured in ... -
Small-scale methane dispersion modelling for possible plume sources on the surface of Mars
(Geophysical Research Letters, 2012-10-11)Intense interest in the characteristics of a methane source on Mars has been spurred by recent observations of a plume structure. The current NASA Mars Science Laboratory and future landers and orbiters will be tasked with ... -
Spectral reflectance properties of zeolites and remote sensing implications
(Journal of Geophysical Research, 2002-09-25)The 0.3- to 26-μm reflectance spectra of a suite of 28 zeolites were measured and analyzed to derive spectral-compositional-structural relationships. Below ~7 μm, the spectra are largely dominated by absorption features ... -
Spectroscopic approaches for studying faint text on a wooden tally from Invincible (1758)
(International Journal of Conservation Science, 2013-01-01)In this study we describe the application of X-ray fluorescence, variable pressure scanning electron microscopy and visible (420-720 nm) hyperspectral imaging to assess the surface properties of a wood tally stick that was ... -

Stability of hydrated minerals on Mars
(Geophysical Research Letters, 2007-10-20)The validity of recent identification of various hydrated minerals (kieserite, gypsum, hexahydrite, nontronite, chamosite, and montmorillonite) on Mars was assessed by exposing these minerals to simulated Martian surface ... -

Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ... -
Surface albedo and spectral variability of Ceres
(The Astrophysical Journal Letters, 2016-01-29)Previous observations suggested that Ceres has active, but possibly sporadic, water outgassing as well as possibly varying spectral characteristics over a timescale of months. We used all available data of Ceres collected ... -
Temporal observations of bright soil exposures at Gusev crater, Mars
(Journal of Geophysical Research, 2011-01-27)The Mars Exploration Rover Spirit has discovered bright soil deposits in its wheel tracks that previously have been confirmed to contain ferric sulfates and/or opaline silica. Repeated Pancam multispectral observations ... -
Visible/near-infrared spectral diversity from in situ observations of the Bagnold Dune Field sands in Gale Crater, Mars
(Journal of Geophysical Research: Planets, 2017-12-13)As part of the Bagnold Dune campaign conducted by Mars Science Laboratory rover Curiosity, visible/near-infrared reflectance spectra of dune sands were acquired using Mast Camera (Mastcam) multispectral imaging (445–1013 ...
