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 ...

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 ...

Electrical sparks inside Martian dust devils have been detected for the first time, reshaping how scientists understand the ...

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 ...

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 ...

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, ...

Billions of years ago, Mars is hypothesized to have been a much warmer and wetter planet featuring active volcanoes and vast liquid water oceans. However, something happened that caused the Red Planet ...

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 ...

Mars’s atmosphere may have once been hundreds of times thicker than it is today, acting as a blanket that protected it from frequent asteroids that ravaged other planets. While the sun and most ...
