Mars, the red planet, owes its iconic color to a very specific chemical process. But new research suggests that this rusty ...

Currently gliding through Gemini’s stars, Mars has fascinated humanity for millennia—from ancient cultures who named it for warriors and gods, to modern scientists discovering its hidden waters and ...

Previous analyses of iron oxide on Mars, based only on observations by spacecraft, didn’t detect any evidence of water, which led researchers to believe that the iron oxide must be hematite.

It seems Mars is another such chromatic case. Until recently, scientists had theories which would explain the planet’s rust-red hue ― they thought a dry, powdery substance called hematite coated our ...

The full disc of Mars is seen with the polar ice caps slightly off-center to the top left and bottom right. Clouds wrap around the planet’s curved horizons. Dark surface markings are clearly ...

The finding offers a tantalizing clue to Mars' wetter and potentially more habitable past because unlike hematite, which typically forms under warmer, drier conditions, ferrihydrite forms in the ...

Planetary researchers had therefore concluded that this particular type of iron oxide must be hematite, formed under dry surface conditions through reactions with the Martian atmosphere over billions ...
