Mars’s red dust may contain ferrihydrite, an iron mineral that forms in water. This suggests ancient Mars had water for ...

While the car-sized spacecraft flew around the Mars system, flight controllers on Earth temporarily lost communication with ...

Mars has been red for millions of years longer than previously thought, suggests new research. The study has "transformed" ...

"We eagerly await the results from upcoming missions like ESA's Rosalind Franklin rover and the NASA-ESA Mars Sample Return, which will allow us to probe deeper into what makes Mars red," adds Colin.

A study suggests Mars takes its red hue from a type of mineral that forms in cool water, which could reveal insights about whether Mars was ever able to support life.
