History of Mars’ water, seen through the lens of Gale Crater

The surface of Mars today is cold, dry, and inhospitable to life. But was it always so? Past research indicates that the Red Planet may have been a very different world more than 3 billion years ago, with warmer weather, … Continue reading

Dormant microbial life in Atacama Desert goes active when wet — true for Mars, too?

It may rain once a decade or less in South America’s Atacama Desert, but tiny bacteria and microorganisms survive there, hinting at the possibility of similar life on Mars, researchers said Monday. [Their report was published in the Proceedings of … Continue reading

Mars: not as dry as it seems

When searching for life, scientists first look for an element key to sustaining it: fresh water. Although today’s Martian surface is barren, frozen and inhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely. … Continue reading

Clays quickly cooked in early Mars steambath

New research suggests that the bulk of clay minerals on Mars could have been formed as the planet’s crust cooled and solidified, not by later interactions with water on the surface as has long been assumed. (…) There are thousands … Continue reading
