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 ...

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 ...

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 ...

For years, scientists have puzzled over how Mars lost the thick atmosphere it once had. That atmosphere was essential for liquid water to exist on the planet’s surface, billions of years ago. Today, ...

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 ...

Mars' atmosphere is one of the planet's most scientifically controversial characteristics. We know that the Red Planet's atmosphere is incredibly sparse, but mounting evidence suggests it once ...

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 ...

During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as ...

It's not entirely clear how neighboring planet Mars went from a presumably life-supporting planet to a place as dead as all others in the solar system. We do know, however, that whatever water and ...
