Mars has ice caps on the south polar, according to the new study Mars is hiding liquid water under all that ice.

In case, if liquid water is proved to exist under the cap, then it is expected that microbial life will exist on the red planet.

Scientists of the European Space Agency are expecting that salty subglacial lake is excited under the thick ice layer.

In 2021, According to NASA, the patch could contain liquid water in places where any water could be expected to remain frozen.

Volcanic activity could explain the mystery behind salt water, however according to the researchers volcanism at the pole was doubtful.

This team used topographic measurements of the south pole surface and computer modeling to back up the case for liquid water.
