Now, new research has found more evidence of the lake, and many smaller salty “ponds” have also been discovered nearby – there is a possibility that there may be life on the red planet.
Scientists were able to collect more specific details about the lake – for example, they estimate that it is 30 kilometers to 30 kilometers (18.6 miles by 18.6 miles) in the area.
“The presence of a satellite lake may have important consequences for astronomy and the presence of habitable remains on Mars,” the statement said.
The pond – which the study describes as “patch water pools or to a lesser extent wet areas” – are of varying size, and are separated from the mainland by strips of dry land.
The discovery is important because it gives us a better idea of Mars’ climate, and chemical makeup. For example, the fact that the lake and its surrounding ponds are still liquid suggests they are “hypersaline”, the study says – meaning they contain a lot of salts. This lowers the melting point, prevents water from freezing despite the cold climate, and may allow them to “survive for extended periods on a geological scale”.
And, of course, there is the question of supernatural life.
A study last year suggested that from 3 to 4 billion years ago, Mars – now cold and inhumane – may have been warm enough to host raindrops and flowing water, which would have created an environment that would Could support a simple life. As the temperature later drops, the water will freeze.
The latest research says that life on Mars cannot simply be a thing of the past.
The study noted, “The prospect of expanded hyperesaline water bodies on Mars is particularly exciting because it is likely to exist for microorganisms.”
If there is indeed life in these salty waters, it can take various forms. Scientists speculate that there may be anaerobes – small organisms that do not require oxygen – or extrophiles, which can survive extreme cold or heat.
There may even be aerobes – organisms that require oxygen. The study noted that salty fishes like lakes or ponds have six times the minimum amount of microbes to breathe.
“Water bodies based on (south polar layered deposits) therefore represent areas of potential astronomical interest and planetary safety concern,” the study concluded, collecting additional data from future Mars missions to the Polar Lake region. Urged to target.
