The primary objective of the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS‐REx) mission is to return to Earth a pristine sample of carbonaceous material from the primitive asteroid (101955) Bennu. To support compositional mapping of Bennu as part of sample site selection and characterization, we tested 95 spectral indices on visible to near infrared laboratory reflectance data from minerals and carbonaceous meteorites. Our aim was to determine… 
Weak spectral features on (101995) Bennu from the OSIRIS-REx Visible and InfraRed Spectrometer
Context. The NASA Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission has obtained thousands of spectra of asteroid (101955) Bennu with the
Phase reddening on asteroid Bennu from visible and near-infrared spectroscopy
Context. The NASA mission OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) has been observing near-Earth asteroid (101955) Bennu in close
Thermal metamorphism of CM chondrites: A dehydroxylation‐based peak‐temperature thermometer and implications for sample return from asteroids Ryugu and Bennu
A peak‐temperature thermometer based on dehydroxylation as measured by analytical totals from electron probe microanalysis (EPMA) of matrices in a number of heated and aqueously altered (but not further heated) CM chondrites is proposed.


Evidence for widespread hydrated minerals on asteroid (101955) Bennu
Evidence for abundant hydrated minerals on the surface of near-Earth asteroid Bennu is revealed in the form of a near-infrared absorption near 2.7 µm and thermal infrared spectral features that are most similar to those of aqueously altered CM-type carbonaceous chondrites.
Relation of the spectroscopic reflectance of olivine to mineral chemistry and some remote sensing implications
Using high-resolution visible and near-infrared diffuse spectral reflectance, we have systematically investigated apparent wavelength shifts as a function of mineral chemistry in the Fe/Mg olivine
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
Reflectance Spectroscopy of Organic Matter in Sedimentary Rocks at Mid-Infrared Wavelengths
Reflectance spectroscopy is a rapid, non-destructive technique capable of characterizing mineral and organic components within geologic materials at spatial scales that range from μm to km. The
Near-Infrared Spectral Variations of Martian Surface Materials from ISM Imaging Spectrometer Data
Abstract Imaging spectrometer data from the ISM instrument on Phobos 2 were used to characterize spatial variations in near-infrared spectral properties of the martian surface, to determine the
