Mars isn’t just dusty—it crackles with electricity. Scientists discovered that dust devils can generate tiny electric sparks, ...

NASA's MAVEN spacecraft, which has orbited Mars since 2014, went quiet abruptly in early December. Efforts to reestablish a ...

Artist's rendering of a solar storm hitting Mars and stripping ions from the planet's upper atmosphere. Mars' atmosphere, once as thick as if not thicker than Earth's today, is leaking into space. "We ...

NASA engineers are working to restore communication with the MAVEN Mars orbiter after the spacecraft went silent in December 2025.

A NASA rover that launched from Florida detected electrical sparks igniting within small dusty tornadoes whirling on Mars' surface.

For decades, scientists treated Martian dust storms as mostly mechanical events, driven by wind and sunlight rather than ...

Mars wasn’t always the cold desert we see today. There’s increasing evidence that water once flowed on the Red Planet’s surface, billions of years ago. And if there was water, there must also have ...

A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded ...

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a ...

Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from freezing or quickly evaporating. However, geological evidence has led scientists to conclude ...

A new study may solve a central mystery of the planet’s 4.6-billion-year history. Despite increasing evidence that water flowed on Mars billions of years ago, scientists have been mystified by what ...
