Researchers based millions of kilometres from Mars have unveiled new evidence for how contemporary features are formed on the Red Planet. Their innovative lab-based experiments on carbon dioxide (CO2) sublimation - the process by which a substance changes from a solid to a gas without an intermediate liquid phase - suggest the same process is responsible for altering the appearance of sand dunes on Mars.
