Clay minerals, or analogously phyllosilicates, are some of the most astonishing minerals
ever discovered on Mars due to their roles as indicators of water-rock interaction. Their …

Hundreds of ancient lake basins detected on Mars via orbital remote sensing represent rare
oases of hydrosphere–atmosphere–lithosphere interactions with great astrobiological …

The Perseverance rover landed in Jezero crater, Mars, to investigate ancient lake and river
deposits. We report observations of the crater floor, below the crater's sedimentary delta …

Before Perseverance, Jezero crater's floor was variably hypothesized to have a lacustrine,
lava, volcanic airfall, or aeolian origin. SuperCam observations in the first 286 Mars days on …

The presence and distribution of preserved organic matter on the surface of Mars can
provide key information about the Martian carbon cycle and the potential of the planet to host …

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

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 …

The SuperCam instrument on the Perseverance Mars 2020 rover uses a pulsed 1064 nm
laser to ablate targets at a distance and conduct laser induced breakdown spectroscopy …

Alluvial rivers are conveyor belts of fluid and sediment that provide a record of upstream
climate and erosion on Earth, Titan, and Mars. However, many of Earth's rivers remain …

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 …
