Abstract The Mars Science Laboratory Curiosity rover arrived at Mars in August 2012 with a
primary goal of characterizing the habitability of ancient and modern environments. Curiosity …

The search for evidence of extraterrestrial life in our Solar System is currently guided by our
understanding of terrestrial biology and its associated biosignatures. The observed …

Observations from orbital spacecraft have shown that Jezero crater on Mars contains a
prominent fan-shaped body of sedimentary rock deposited at its western margin. The …

Establishing the presence and state of organic matter, including its possible biosignatures,
in martian materials has been an elusive quest, despite limited reports of the existence of …

Geological evidence shows that ancient Mars had large volumes of liquid water. Models of
past hydrogen escape to space, calibrated with observations of the current escape rate …

Collocated crystal sizes and mineral identities are critical for interpreting textural
relationships in rocks and testing geological hypotheses, but it has been previously …

Abstract The Glen Torridon (GT) region in Gale crater, Mars is a region with strong clay
mineral signatures inferred from orbital spectroscopy. The CheMin X‐ray diffraction (XRD) …

The composition and physical properties of martian regolith are dramatically better
understood compared to just a decade ago, particularly through the use of X-ray diffraction …

Mars' sedimentary rock record preserves information on geological (and potential
astrobiological) processes that occurred on the planet billions of years ago. The Curiosity …

Perseverance explored two geological units on the floor of Jezero Crater over the first 420
Martian days of the Mars2020 mission. These units, the Máaz and Séítah formations, are …
