Now, new research has found more evidence of lakes, and also revealed many smaller saline “lakes” nearby – more likely to have life on the Red Planet.
Scientists were able to gather more specific details about the lake – for example, they estimate that the area is 30 by 20 kilometers (18.6 by 12.4 miles).
“The presence of subglacial lakes could have significant consequences for astrology and the presence of habitable structures on Mars,” the statement added.
These lakes – which the study describes as “patch chi water pools or slightly wet areas” – are of different sizes, and are separated from the main lake by dry land strips.
The discovery is important because it gives us a better representation of the Martian climate and chemical makeup. For example, the fact that the lake and the surrounding lakes are still liquid indicates that they are “hypersalin,” the study said – meaning they contain a lot of salts. This lowers the melting point that prevents water from cooling despite the colder climate and perhaps allows them to “survive geographically extended for a longer period of time.”
And, of course, the question of life in the outside world.
A study last year suggested that between two billion billion years ago, Mars – now cold and inhabited – could be warm enough to share rainstorms and running water, creating an environment that could support a simpler life. As the temperature later decreases, the water will freeze.
The latest research shows that life on Mars cannot just be a thing of the past.
“The potential for extended hypersalin water bodies on Mars is particularly exciting due to the possibility of the existence of microbial life,” the study said.
If this salt water really has life, it can take many forms. Scientists speculated that there may be anaerobes – small organisms – that do not need oxygen – or extreme files, which can withstand extreme cold or heat.
There may also be a robot – an organism that needs oxygen. Saline brins, such as lakes or ponds, require the least amount of oxygen for microbes to breathe, the study found.
“Water bodies based on the south (polar polar deposits) therefore represent potential astrological interests and areas of planetary security concern,” the study concluded, targeting the polar lake region to collect additional data. Requested the mission.
