Clouds and sand on the horizon of Mars

Posted in: Gallery

View from Mars Victoria Crater taken by the Opportunity Rover (2006)1. The sand is rich in reddish iron oxides, which are also suspended as dust in the CO2 atmosphere, leading to pink-red light scattering. Water ice clouds move at ~10 meters per second and should lead to snowing in some areas.
