Mars has an active, electrically charged surface where dust storms and spinning dust devils regularly move and reshape the ...

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 ...

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 ...

(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 ...

WASHINGTON (Reuters) – NASA’s Perseverance rover has obtained evidence that the atmosphere of Mars is electrically active, detecting electrical discharges – what one scientist called “mini-lightning” ...

The study presents the first in-situ evidence of electrical activity in the Martian atmosphere, identifying 55 distinct triboelectric discharge events. These electrical discharges, unlike terrestrial ...

Mars is cold, parched, and extremely dusty. Powerful gusts of wind kick up literal tons of reddish dust that often takes the form of whorls known as dust devils. These winds also shroud the planet in ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were carved by rivers, so it was once warm enough for liquid water. How—and ...

Scheduled to launch late this year, the Mars Atmosphere and Volatile Evolution (MAVEN) will be the first mission devoted to understanding the upper atmosphere of Mars. The goal of MAVEN is to ...
