Striking discovery: components for life on Mars are underground

NASA’s Perseverance roverWhile searching for life on Mars, discovered new findings. The vehicle that searches for the old life, Life under the Red Planet found the necessary components for. Researchers believe that these life forms microbial life He said there might be chemical reactions to support it.

Study in the journal Astrobiology published. ABD’deki Brown University researchers examined meteorites. Bouncing off the surface of Mars and landing on Earth Mars meteoritesThey looked at the chemical composition of. Analysis, these rocks if they are in consistent contact with water chemical energy it will produceHe showed me. These components are similar to reactions that support surviving microbial communities in the undiscovered depths of the Earth. Because these meteorites represent large areas of the Martian crust, the findings suggest that much of the Martian subterranean could be habitable.

There is enough energy to sustain life on Mars

From NASA’s Jet Propulsion Laboratory Dr. Jesse Tarnas he said:

“Wherever there is water on Mars’ surface, it is likely that there is sufficient chemical energy to support microbial life beneath the surface. We don’t know if life arose beneath the surface of Mars, but if so, we think there will be enough energy to survive to this day. “

In recent years, scientists have discovered that the depths of the Earth are home to a large biome. Deprived of sunlight, these creatures survive using components similar to chemical reactions produced when rocks come into contact with water. One of these reactions is radiolysis, which occurs when radioactive elements inside rocks react with water trapped in pore and crack spaces. The reaction splits water molecules into its constituent elements, hydrogen and oxygen. Then the liberated hydrogen dissolves in groundwater, while minerals such as pyrite (iron sulfide) absorb oxygen to form sulfate minerals. Microbes digest dissolved hydrogen as fuel and use the oxygen preserved in sulphates to burn this fuel.

Life is sought on Mars

Scientists found that sulfate-attenuating microbes at Canada’s Kidd Creek Mine, For over a billion years without seeing the light of day discovered that it lives in water. Tarnas is also working with Brown University professor Jack Mustard and Professor Barbara Sherwood Lollar from the University of Toronto to better understand these underground systems. The team is looking for similar habitats on Mars and elsewhere in the Solar system.

Researchers searched for life components

Researchers investigated whether components of radiolysis-induced habitats were found on Mars. These; radioactive elements such as thorium, uranium, potassium, sulfide minerals that can be converted to sulphate, rock units with sufficient pores to hold water. Of NASA Curiosity as well as data from navigators and other spacecraft Meteorites from marsThey also examined.

Study, several different Mars meteorite type produced the same result. Accordingly, all components exist in sufficient quantities to support Earth-like habitats. Especially for meteorites derived from shell rocks older than 3.6 billion years, which have the highest potential for life. Because, unlike Earth, Mars does not have a plate tectonic system that constantly recycles crust rocks. So these ancient plots remained largely intact.

Previous research has found evidence of active groundwater on Mars in the past, the researchers said. There are now reasons to believe that groundwater exists. For example, one study revealed that Mars may have an underground lake under the southern ice cover. With this new work, the team Energy for life wherever there is groundwater showed that it was.
