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.

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

“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 ...

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 ...

A new study by researchers including those at the University of Tokyo revealed that atmospheric gravity waves play a crucial ...

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 by researchers including those at the University of Tokyo revealed that atmospheric gravity waves play a crucial ...

If you’ve ever looked at Mars through a telescope, you probably noticed its two polar ice caps. The northern one is made largely of water ice—the most obvious sign that Mars was once a wetter, warmer ...

A new international study partially funded by NASA on how Mars got its iconic red color adds to evidence that Mars had a cool but wet and potentially habitable climate in its ancient past.

A groundbreaking study, financed in part by NASA, reveals the mystery behind Mars' iconic red color, linking it to the presence of water-rich iron mineral ferrihydrite, suggesting a cooler, wetter, ...

“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 ...
