Abstract The Medusae Fossae Formation (MFF) is one of the largest sedimentary deposits
on Mars. The origin of the MFF is uncertain, though several processes including volcanic …

Lacustrine sedimentary rocks of the Murray formation, Gale Crater, Mars, contain evidence
for early diagenetic mineral precipitation. High‐resolution MAHLI images permit detailed …

Mars' surface bears the imprint of valley networks formed billions of years ago. Whether
these networks were formed by groundwater sapping, ice melt, or fluvial runoff has been …

ChemCam has observed a wide range of diagenetic features along the Curiosity rover
traverse including pervasive Ca-sulfate veins. Observations by multiple instruments on …

Earth's most severe climate changes occurred during global-scale “snowball Earth”
glaciations, which profoundly altered the planet's atmosphere, oceans, and biosphere …

On a planet as cold and dry as present-day Mars, evidence of multiple aqueous episodes
offers an intriguing view into very different past environments. Fluvial, lacustrine, and eolian …

Oxygen and HCl gas releases detected by the Sample Analysis at Mars (SAM) instrument on
board the Mars Science Laboratory Curiosity rover in several Gale Crater samples have …

A thin, patchy layer of airfall dust covers rock surfaces examined by the Mars Science Lab
rover Curiosity and complicates interpretation of textures in Mars Hand Lens Imager images …

There is abundant evidence for aqueous processes on Noachian terrains across Mars;
however, key questions remain about whether these processes continued into the …

Identification of phyllosilicates and short-range ordered (SRO) materials on Mars has led to
new insights about the early martian climate and habitability. Phyllosilicates were first …
