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 ...

For the first time on a global scale, 20 years of observations on Mars have been condensed into a single study led by Francisco Brasil and Pedro Machado, both researchers from the Faculty of Sciences ...

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 new study revealed that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. The findings, based on long-term atmospheric data, ...

Mars just gave up one of its oldest secrets — and it took a decade, a spacecraft, and a cosmic cannonball to catch it in the act. For the first time, NASA’s MAVEN mission has directly observed a ...

Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture ...

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 ...

A new study published in the Advances in Space Research journal suggests that moisture in the Martian atmosphere could serve ...

The thermal impact of dust storms on Mars is significant, and is thought to play a similar role to that of water vapor in Earth’s atmosphere. A new study by researchers including those at the ...
