For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today. A new study published online on September 2, ...

A remarkable image captured by ESA’s Mars Express orbiter has brought renewed attention to a complex and heavily eroded crater on Mars. The Deuteronilus Cavus, a nearly circular 75-mile-wide (120 ...

A European Mars probe captured a stunning view of a Martian crater that's rich in many of the features that help scientists reconstruct the planet's dynamic history over billions of years. Located in ...

NASA's robotic rover on Mars has found signs that a vast and hospitable lake once spread over the now-desolate Martian surface, providing a potential home to past life for centuries or longer. The ...

Jezero Crater’s rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseverance’s discoveries guide future sampling and strengthen ...

New research using NASA's Perseverance rover has uncovered strong evidence that Mars' Jezero Crater experienced multiple episodes of fluid activity—each with conditions that could have supported life.

Mars has experienced multiple ice ages, with each one leaving less ice than the last. By studying craters that serve as “ice archives,” researchers traced how the red planet stored and lost its water ...
