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 ...

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 between human explorers and long-term settlement. A growing body of research ...

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 ...

NASA’s Curiosity rover has found evidence that chemistry in the surface material on Mars contributed dynamically to the makeup of its atmosphere over time. It’s another clue that the history of 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 ...

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, ...

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 ...

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 ...

Mercury, Venus, and Mars sit within the same general neighborhood as Earth, yet each has followed a radically different path. One kept a magnetic field against the odds. Another trapped so much heat ...

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 ...
