Liquid lake under the ice cap on Mars - the result of volcanic activity

Specialists from the University of Arizona (United States of America) argue that Mars is a geologically active space object, in the depths of which there are igneous chambers. Thus, it is possible to explain the presence of water in a liquid consistency under the southern ice cap of the fourth planet of the solar system.

American scientists said that the statement of European colleagues about the existence of water under a crust of ice at the south pole of Mars was true. They determined the conditions under which water can remain in a liquid state for a long period of time.

One of the hypotheses explains this heat, which comes from the depths of the planet, due to which ice is melting. The other is associated with the salt contained in the ice in an amount that lowers the melting point.

However, the simulation carried out eliminated the option with salt, because it is not able to give such a volume of liquid water. Thus, magmatic chambers under the surface of Mars, which just help the ice to melt, became the main version.

About 300 thousand years ago, molten rocks began to rise to the surface, but the power of the flow was insufficient to break through the crust. Magma did not find a way out and simply accumulated in the voids, and the heat from it subsequently came out at the base of the Red Planet ice sheet. Scientists say that this process has not stopped yet.

From 2012 to 2015, the South Polar Cap Planum Australe was scanned with the aid of the ESA-launched MARSIS radar, the purpose of which was to search for liquid water and water-ice under the surface of Mars. The hard work produced fruit: at a depth of 1.5 kilometers, signs of the existence of water were found under a thick layer of ice.
