Researchers from the European Space Agency (ESA) reported on the discovery of a network of salt reservoirs under the glacier at the southern pole of Mars.
Science Alert writes about the discovery, pointing out that new natural water reservoirs were found near the already known large underground Martian polar lake.
It was discovered back in 2018. At that time, the researchers did not even think that under the surface of the Red Planet may be a whole network of reservoirs.
All of them are at a depth of about 1.5 kilometers. To date, found seven lakes, the largest of which is about 20 kilometers long.
The surface temperature at the South Pole is estimated to be minus 113 degrees Celsius and is gradually getting warmer with depth.
According to calculations, at a depth of one and a half kilometers, the temperature hardly rises above minus 68 degrees Celsius. However, water in lakes still remains liquid – most likely due to the high concentration of salt, which affects the freezing temperature.
The presence of water increases the probability of microbial life on Mars or under its surface. It is believed that four billion years ago Mars was warm and humid, but eventually turned into a desert world because of the disappearance of the magnetic field.
The researchers believe that the found lakes can preserve individual life forms. In the future, the scientists are going to send special vehicles to the poles of Mars to better study the liquid water on the planet.
As reported by TOP NEWS, in late July, NASA sent to Mars Atlas V rocket with the Mars rover Regess, which will search for traces of life on the Red planet. According to calculations, the landing of the spacecraft on the Martian surface will occur on February 18, 2021.
