Scientists find evidence of multiple underground lakes on Mars

After observing an area of ​​about 75,000 square kilometers, they found locations that reflected those signals in a way that indicates the presence of water trapped under a kilometer of ice. The main lake, the one discovered in 2018, measures 30 kilometers or 19 miles in diameter, while each of the three smaller lakes surrounding it is only a few kilometers in diameter.

Although the scientists’ findings are promising, some experts still believe we won’t find lakes on the red planet at all. Jack Holt, a planetary scientist who is part of NASA̵

7;s Mars Reconnaissance Orbiter program, does not believe that there is enough heat flow beneath the planet’s surface for water to remain liquid. And even if we find liquid water under the Martian ice, that doesn’t automatically mean we’ll find life too. You see, lakes have to be very salty to stay liquid, but their salt content doesn’t have to exceed five times that of seawater to be able to sustain life. As John Priscu, an environmental scientist at Montana State University said Nature:

“There is not much active life in the … brackish pools in Antarctica. They are only in brine. And it could be so. [on Mars]. “
