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 does not have Earth's kind of magnetic shield, so it has often been treated as the solar system's more exposed world. It is a planet left to take the sun's blows with far less protection. But ...

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 is the fourth planet from the sun and has a distinct rusty red appearance and two unusual moons. The Red Planet is a ...

(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 ...

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 ...

A new study by researchers including those at the University of Tokyo revealed that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high ...

In December 2023, scientists looking at Mars data stumbled across something completely unexpected—observations of an atmospheric effect never before seen in the Red Planet's atmosphere. Using ...

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 ...

A veteran spacecraft has sniffed the Martian atmosphere for the last time. More than a decade after the MAVEN orbiter arrived at Mars and six months after it unexpectedly went quiet, NASA has ...
