Mars is covered in a fine dust that’s rich in iron oxides. You might know these compounds better as rust, the same stuff that forms when you leave an old bicycle out in the rain too long. On Earth, ...

NASA’s Perseverance rover found pale rocks containing kaolinite on Mars, a mineral that forms in warm, wet conditions.

“Early Mars has historically been thought of as either ‘cold and dry’ or ‘warm and wet,’” says Alberto Fairén, an astrobiologist at the Center for Astrobiology in Madrid and at ...

These conditions were very different from the dry, cold environment of Mars today." "The study is really a door-opening opportunity," study co-author Jack Mustard said in a statement. "As exciting ...

A new study claims that a mineral found in Mars' dust called ferrihydrite, which forms in the presence of cool water, is ...

The presence of ferrihydrite implies that rather than the dry land we think of when we think of Mars, the planet had a period of cold and wet conditions. Previous research did not detect water in ...

This in turn suggests that the ferrihydrite “formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current hyper-arid environment.” ...

“The small deformation rates indicate that the upper mantle of Mars is cold, highly viscous and much stiffer than Earth's upper mantle," comments Ana-Catalina Plesa, geophysicist at DLR and co-author ...

"Mars is still the Red Planet ... into the planet’s past environment — was it once warm and wet, or always cold and dry? And, more importantly, did it ever support life?
