Mars Finds a Giant Liquid Lake Under the North Pole

This may be our greatest chance of finding life on the Red Planet.

We finally know where all those waters on Mars are hidden up to now!

This latest discovery was made with the use of a spacecraft radar device that is orbiting Mars. Italian scientists have found a gigantic liquid reservoir, 20 kilometers wide, hidden under 1.5 kilometers of the ice layer in the north pole.

The researchers say it looks like glacial lakes trapped beneath the North and South Pole glaciers in the world. Also, as in the glacial lakes around the world, there may be unexpected life here as well.

The glacial lake was supposed to be one of the places where water is likely to be found in the long-suffering Red Planet, but researching the glaciers is not an easy task on Earth.

Scientists have used radar-equipped satellites in recent years to uncover the mysteries of the secret waters of our planet.

A team of researchers from a number of institutes in Italy used a similar technology to study Mars's polar glacier in Mars. The European Space Agency's Express-named space vehicle, which has been turning around Mars since 2003, has a specially designed vehicle for underground surveys.

Mars Underwater and Ionosphere Advanced Radar Measurements (MARSIS) is a vehicle named, trying to find Mars surface characteristics using radar. For more than 12 years he was searching for signs of underground liquid water.

The research team has been conducting a serious research in a region named Planum Australe in May, 2012, and in December 2015, some 200 kilometers wide of the southern glacier layer.

They took 29 waves of radar profiles, dividing radio waves from the depths of Mars and gathering the returning signal with a receiver.

Scientists are working on subterranean qualities by measuring the changes between the transmitted signal and the returned signal. The radar returning from the water returns stronger or 'brighter' than the radar returning through the rock or trough.

The research team found this in their radar results: There was an abnormally bright spot in Planet Australe.

A subliminal anomaly reflected in such a brilliant manner can be explained by other things, such as bubbles or carbon dioxide, which are very cold and pure water. However, the research team carried out various animations and discovered that the reflection profile did not match up well with liquid results as the corresponding results.

But there was another major problem: the temperature of the water mass was estimated to be around -68.15 Celsius.

This amount is well below the freezing temperature, even compared to the South Pole lakes of the hypertrophic South Pole. These lakes are kept in liquid state at -13 Celsius due to the salt they contain.

However, the water can still hypothetically still remain liquid. We know that sodium, magnesium and calcium salts are abundant in Mars; they were found on the surface.

If these substances enter and dissolve in the water, they may fall below the freezing temperature below -74 Celsius when they are joined by the pressure of the upper glacier layer.

Life in the glacial lakes of the world was found. It has already been suggested that life can also be accommodated by a glacier on Mars. This discovery, again, makes the prospect more evident than ever before.

Brendan Burns, an astrobiologist at the University of New South Wales who does not participate in the study, says: "There is evidence that microbial life exists in the waters below the poles in the world; moreover, there are even microbes that can live in ice vessels "

"This finding, which shows that similar scenarios have been experienced on Mars, not yet experimentally determined, but that potential liquid water can be found under the surface of Mars, opens doors to the fascinating areas of space exploration."

There is good reason to remain calm in this regard. It is highly probable that the salt concentration needed to remain hydrated is too high to allow for the sheltering of life.

At this point or near future, we have no vehicle to sample this water.

But it is much more accessible than the other candidates Europa and Enceladus in search of life in the Solar System; Moreover, the water itself may provide some clues as to what Mars might have been about the climate history and what happened to the ocean that had long since disappeared.

In addition, because the team now demonstrates the method they use, other researchers know how to investigate water deposits like this on the Red Planet.

But let's take a minute to get excited about the possibility of Martian micros.

Brad Tucker, an astrophysicist at the Australian National University who does not participate in the survey, says: "This discovery by Mars Express is incredible"

"For decades, we were finding evidence of liquids flowing either in ice or in the past. We now know that there is liquid water on Mars, and just like the underwater lakes in the South Pole on Earth, there are also those lakes on Mars."

"Every month, new discoveries are made that bring us closer to answering that basic question. That question; Is there life beyond the world? "
