Mars has experienced six to twenty ice ages over the past several hundred million years. This is the conclusion geologists have come to based on the analysis of images of lobed alluvial margins, according to the journal Proceedings of the National Academy of Sciences.
Today it is believed that once in the past, a favorable climate could prevail on the Red Planet, and liquid water could exist on its surface. However, such conditions on Mars did not exist for long, and already at the beginning of the Hesperian period, that is, about 3.7 billion years ago, the celestial body turned into a dry, cold desert. Why such a radical change took place remains a matter of debate, as well as how exactly the climate has changed throughout the history of the planet.
