The Martian subsurface as a potential window into the origin of life
Few traces of Earth's geologic record are preserved from the time of life's emergence, over
3,800 million years ago. Consequently, what little we understand about abiogenesis—the …

Aqueously altered igneous rocks sampled on the floor of Jezero crater, Mars
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 …

Temperature trends for reaction rates, hydrogen generation, and partitioning of iron during experimental serpentinization of olivine
A series of laboratory experiments were conducted to examine how partitioning of Fe among
solid reaction products and rates of H 2 generation vary as a function of temperature during …

Modern water/rock reactions in Oman hyperalkaline peridotite aquifers and implications for microbial habitability
Abstract The Samail ophiolite in Oman is undergoing modern hydration and carbonation of
peridotite and may host a deep subsurface biosphere. Previous investigations of …

Paleo-rock-hosted life on Earth and the search on Mars: a review and strategy for exploration
Here we review published studies on the abundance and diversity of terrestrial rock-hosted
life, the environments it inhabits, the evolution of its metabolisms, and its fossil biomarkers to …
