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

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 …

INTRODUCTION Remote observational data suggest that large bodies of standing water
existed on the surface of Mars in its early history. This would have required a much wetter …

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 …

INTRODUCTION The primary goal of NASA's Curiosity rover mission is to explore and
quantitatively assess a local region on Mars' surface as a potential habitat for past or present …

The rover Opportunity has investigated the rim of Endeavour Crater, a large ancient impact
crater on Mars. Basaltic breccias produced by the impact form the rim deposits, with …

Precipitated minerals, including salts, are primary tracers of atmospheric conditions and
water chemistry in lake basins. Ongoing in situ exploration by the Curiosity rover of …

The surface of Mars is cold, dry, oxidizing, acidic and inhospitable to life. Similar conditions
may have persisted for billions of years, suggesting that the best place to search for …

Clay minerals provide indicators of the evolution of aqueous conditions and possible
habitats for life on ancient Mars. Analyses by the Mars Science Laboratory rover Curiosity …

The composition of the ancient martian crust is a key ingredient in deciphering the
environment and evolution of early Mars. We present an analysis of the composition of large …
