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 ...

What happens to Mars’ atmosphere when it gets hit with space weather? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated novel methods ...

A small team of planetary scientists, astrophysicists and space flight researchers affiliated with several institutions in the U.S. and one in France has made the first direct detection of atmospheric ...

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 ...
