The thin air of Mars has long been treated as a problem to be solved, a hostile mix of carbon dioxide and dust that stands ...

All evidence points to Mars having had a carbon dioxide-rich atmosphere billions of years ago, but insufficient carbonates in Martian soil challenge this theory. Now, a new study using data from ...

Mars' missing atmosphere may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested. According to the researchers, ancient water trickling through Mars' rocks ...

Researchers say they have gathered evidence of Mars' atmosphere sputtering for the first time. Understanding how Mars' atmosphere has changed over time will undoubtedly help us discover more about the ...

Creating a composite photograph of the images taken by the Color and Stereo Surface Imaging System (CaSSIS) aboard the Trace Gas Orbiter, ESA scientists found that the dust and gas layers of Mars' ...

New research suggests Mars' missing atmosphere -- which dramatically diminished 3.5 billion years ago -- could be locked in the planet's clay-covered crust. Water on Mars could have set off a chain ...

Martian dust creates frictional electricity that can change the planet's chemical composition.

We've learned a great deal about Mars over the last two decades, thanks to the long-term success of multiple orbital missions and rovers. It's now considered likely that liquid water once flowed ...

NASA's Curiosity rover has uncovered evidence of a past carbon cycle on Mars. This breakthrough provides scientists with new insights into the Red Planet's potential to have hosted life. Data ...

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