The first samples collected by the Mars 2020 mission represent units exposed on the Jezero
Crater floor, from the potentially oldest Séítah formation outcrops to the potentially youngest …

Fe-rich minerals are ubiquitous on the earth's surface and on Mars, and interactions of iron
minerals with chlorate (ClO3–) and/or nitrate (NO3–) may influence the redox cycling of …

Recent measurements from Mars document X-ray amorphous/nano-crystalline materials in
multiple locations across the planet. Despite their prevalence, however, little is known about …

Both high and low calcium pyroxene minerals have been detected over large portions of the
martian surface in addition to widespread salts in martian soils and dust. Calcium pyroxenes …

The availability of terrestrial sites that are martian analogs allows researchers to investigate
Mars using knowledge gained on Earth. Among the terrestrial analog sites for Mars is …

A diverse suite of carbonate minerals including calcite (CaCO 3) and magnesite (MgCO 3)
have been observed on the martian surface and in meteorites. Terrestrial carbonates usually …

Pyroxene minerals are a significant component of Shergottite-Nakhlite-Chassignite (SNC)
meteorites (eg,) and detected across large areas of Mars' surface (eg,). These minerals are …

Past aqueous conditions in the Murray formation at Gale crater, Mars contain important clues
to interpret ancient environments, potential habitability, and the biosignature preservation …

Salts and basalt are widespread on the surface of Mars. Therefore, basalt-brine interactions
may have significant effects on both the aqueous history of the planet, and near-surface …

Perchlorate salts and the ferric sulfate mineral jarosite have been detected at multiple
locations on Mars by both landed instruments and orbiting spectrometers. Many perchlorate …
