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 ...

Moisture extracted from the atmosphere of Mars could provide a valuable alternative water supply if humans are ever to inhabit the red planet, a study has found. However, the research from a ...

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 ...

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 ...

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, ...

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 ...

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 YORK) — Mars is a cold, dry, desert-like planet. But billions of years ago, scientific evidence suggests that it had a thick atmosphere, which kept it warm enough to support flowing water on its ...

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 ...
