Meteoritics &Planetary Science, EarlyView.Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Meteoritics &Planetary Science, EarlyView.Abstract This study investigates the petrography and mineralogy of three L‐type ordinary chondrite meteorites: Northwest Africa (NWA) 4137 (L6), Homestead (L5), and Kunashak (L6). We studied the shock‐related deformation features in the matrix and the characteristics of the melt veins, including the presence or absence of high‐pressure (HP) phases. Our

A mineralogical instrument for planetary applications [PDF]
, 1994 The mineralogy of a planetary surface can be used to identify the provenance of soil or sediment and reveal the volcanic, metamorphic and/or sedimentological history of a particular region.

Meteoritics &Planetary Science, EarlyView.Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

The Branched GDGT Isomer Ratio Refines Lacustrine Paleotemperature Estimates
Geochemistry, Geophysics, GeosystemsBranched glycerol dialkyl glycerol tetraethers (brGDGTs) are membrane‐spanning lipids synthesized by bacteria in numerous substrates. The degree of methylation of the five methyl brGDGTs in both soils and lake sediments, described by the MBT′5Me index ...

Meteoritics &Planetary Science, EarlyView.Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

The Planetary Science JournalThe analysis of micrometer-sized ice grains emitted into space by Saturn’s moon Enceladus suggests that the moon’s subsurface ocean may be habitable. However, the formation conditions of these ice grains are largely unknown.
