💨 Abstract

A new study suggests that the rusty dust on Mars is older than previously assumed, formed during volcanic eruptions when water was widespread on the planet's surface. The dust best matches a mixture of basalt, sulphites, and ferrihydrite, a form of rust that forms quickly in the presence of cool water. The discovery has important implications for understanding Mars' past and present climate, chemical history, and potential for life.
