Essentially, it’s rust. That red-tinted iron oxide disintegrated into dust and spread across the planet on wind currents for billions of years—as it continues doing today. However, different ...

Dust swept from the Sahara desert provides life at the bottom of the marine food chain with a critical nutrient. Without the ...

Now a startup called Stardust seeks something more ambitious: developing proprietary geoengineering technology that would ...

Over billions of years this rusty material – iron oxide – has been eroded down into dust and spread all around the planet by winds, a process that continues today. Exciting new research ...

Together, orbiters and landers have provided scientists with data showing that Mars’ red color comes from rusted iron minerals within the dust that coats the planet. At some point, iron within ...

Most critically, there is an abundance of silica dust in addition to iron dust from basalt and nanophase iron, both of which are reactive to the lungs and can cause respiratory diseases.

The red coloration comes from iron minerals in Mars’ dust—no surprise there. But a team of ESA and NASA scientists now think that Mars rusted earlier in its ancient past than previously known ...
