According to a triplet of new studies, the proof of ‘subsurface lakes’ far beneath the ice cap at Mars’ south pole could be because of clay. Referring to proof gathered from a radar instrument on board the European Space Agency Mars Express orbiter, a group of researchers from Italy proposed that the chance of subsurface lakes underneath the ice caps at Mars’ south pole.

As per NASA, the radar signals change when they are reflected off various materials. After analysts from Italy’s Istituto Nazionale di Astrofisica published the paper on lake, around 80 Martian polar researchers met for a worldwide conference in Ushuaia. There were bunches of discusses the subsurface lakes. They additionally talked about the chance of brine bringing down the freezing point of the water enough to keep it fluid.

Jeffrey Plaut of Nasa’s Jet Propulsion Laboratory and Aditya Khuller, a doctoral student, examined 44,000 radar echoes across 15 years of MARSIS data. They likewise turned up handfuls all the more splendid reflections like the 2018 investigation. A considerable lot of those nearby signals in regions near the surface were discovered, where it ought to be excessively cold for water to stay fluid.
