Before going to Mars, the first thing to consider is the resources needed to maintain normal life. Interestingly, under the dusty Southern Martian ice sheet, there may be a large pond full of water. A new study, led by researchers at Rome tre University in Italy, not only reinforces the evidence for this hidden lake, which was first discovered in 2018, but also extends the scope to three new areas. The researchers used radar data from the European Space Agency’s Mars Express orbiter to initially monitor the red planet’s liquid water, which was published in the journal Nature astronomy on Monday. < / P > < p > at the same time, ESA said in a statement: “now, considering more data analyzed in different ways, researchers have found three new Martian ponds again.”. < / P > < p > research shows that Martian lakes appear to be hidden under thick ice, with the largest of nearly 19 miles (30 kilometers) and surrounded by a series of smaller ponds. < / P > < p > secondly, to remain liquid at low temperatures, the water here must be extremely salty. However, another study in 2019 suggests that volcanic activity may help prevent the freezing of groundwater on Mars. Although the current Martian surface has been unable to store water stably, the new study has laid a theoretical foundation for the possibility that ancient lakes may have existed underground (millions, even billions of years ago), according to ESA.
