NASA’s Perseverance rover has uncovered powerful new evidence that Mars’ Jezero Crater once hosted multiple rounds of flowing water, each creating conditions that could have supported life.

A new AI-driven global survey shows Mars’ dark slope streaks form through dry dust avalanches, not liquid water.

For years, scientists have been intrigued by mysterious dark streaks running down the slopes of Martian cliffs and craters. These marks, called slope streaks and recurring slope lineae (RSLs), have ...

According to a deep-learning analysis, most dust avalanches on Mars are driven by wind and dust, not by impacts or quakes.

Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth? A discovery made by a NASA rover has offered a clue to this mystery, new research said ...

Satellite images of the Red Planet suggest scientists were wrong about these strange Martian features. First identified in the 1970s by NASA's Viking mission, long, dark markings snake down Martian ...
