Evolution of Occator Crater on (1) Ceres
(The Astronomical Journal, 2017-02-17)The dwarf planet Ceres (diameter 939 km) is the largest object in the main asteroid belt. Recent investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body which ... -
Manganese-rich olivines: Identification from spectral reflectance properties
(Journal of Geophysical Research, 1997-11-25)Reflectance spectra of manganese-rich olivines were examined to determine which spectral features allow these minerals to be distinguished from forsteritic-fayalitic olivines. The results indicate that manganese-rich ... -
Mineralogic constraints on sulfur-rich soils from Pancam spectra at Gusev crater, Mars
(Geophysical Research Letters, 2007-07-06)The Mars Exploration Rover (MER) Spirit excavated sulfur-rich soils exhibiting high albedo and relatively white to yellow colors at three main locations on and south of Husband Hill in Gusev crater, Mars. The multispectral ... -
Optical and radiometric models of the NOMAD instrument part I: the UVIS channel
(Optics Express, 2015-11-09)The NOMAD instrument has been designed to best fulfil the science objectives of the ExoMars Trace Gas Orbiter mission that will be launched in 2016. The instrument is a combination of three channels that cover the UV, ... -
Optical and radiometric models of the NOMAD instrument part II: the infrared channels - SO and LNO
(Optics Express, 2016-02-16)NOMAD is a suite of three spectrometers that will be launched in 2016 as part of the joint ESA-Roscosmos ExoMars Trace Gas Orbiter mission. The instrument contains three channels that cover the IR and UV spectral ranges ... -
Pyroxene reflectance spectra: Minor absorption bands and effects of elemental substitutions
(Journal of Geophysical Research, 2002-06-13)Reflectance spectra of a suite of compositionally diverse pyroxenes exhibit variable spectral properties which are associated with various elemental substitutions. Those associated with transition series elements, such as ... -
Pyroxene spectroscopy revisited: Spectral-compositional correlations and relationship to geothermometry.
(Journal of Geophysical Research, 1991-12-25)Pyroxene reflectance and transmittance spectra have been examined in a search for systematic relationships between spectral features and compositional variations and to assess the applicability of reflectance spectroscopy ... -
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 ... -

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 ... -
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 ...
