While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have […]
The identification of terrestrial analogs is a key strategy for advancing our understanding of the geological and geochemical evolution of Mars.
Every winter, a layer of carbon dioxide frost (dry ice) forms on the surface of Mars. At its greatest extent in mid-winter, this frost reaches from the poles down to […]
A Science Strategy for Human Exploration of Mars, charts a bold, scientifically based blueprint for humanity’s greatest cosmic adventure—sending explorers to Mars to answer the universe’s most profound questions: Is […]
Marine sediments host a vast deep biosphere, yet how microorganisms persist under severe energy limitation and govern long-term organic carbon (OC) preservation remains poorly understood.
Life thrives in Earth’s most inhospitable environments, from boiling hydrothermal vents to hypersaline lakes and frozen polar deserts, thanks to the remarkable adaptations of extremophilic microorganisms.
A discovery by a South Korean research team suggests that impact-generated lakes may have fostered early oxygen-producing life.
Over 3.5 years of exploration in Jezero Crater, the Perseverance rover has explored several geological units of diverse origins and natures, performing multi-technique remote analyses of the chemistry and mineralogy […]
The agency’s six-wheeled geologist took a self-portrait during its survey of an ancient landscape that may predate the formation of Jezero Crater itself.
Volcanic eruptions and glacial ice have occurred at virtually all latitudes and altitudes throughout Mars history.
