CAMBRIDGE, Mass. — Three and a half billion years ago, Mars underwent a dramatic transformation. Its thick blanket of air ...

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 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, ...

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 ...

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, ...

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 ...

Mars entry vehicle aerothermodynamics encapsulates the study of fluid dynamic and thermal phenomena encountered when a spacecraft penetrates the thin, predominantly CO₂ atmosphere of Mars. This field ...

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 ...

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a ...
