Although no life has been found on the surface of Mars, a new study by astrophysicist and scientist Dimitra Atri of the Abu Dhabi Space Center in NYU found that underground conditions could support it. The underground layer, which is less harsh and has traces of water, has never been studied. According to Atri, the constant bombardment of the penetrating space rays of the galaxy (GCR) can provide the energy needed to stimulate the organic activity taking place there.

Atri studied the biological potential of radiation-induced radiation-induced chemical equilibrium in the galaxy’s underground environment; the results are published in the journal Scientific reports.

There is growing evidence that there is an aquatic environment on ancient Mars, raising the question of the possibility of a life-sustaining environment. The erosion of the Martian atmosphere has drastically changed its climate: surface water has disappeared, the space of the planet has shrunk, and only surface water has remained in the form of brine and water ice deposits. Life, if it ever existed, would have had to adapt to harsh modern conditions, including low temperatures and surface pressures and high levels of radiation.

There are traces of water in the dungeon of Mars in the form of water ice and brine, and radiation-induced redox chemistry takes place there. Using a combination of digital models, space mission data, and deep cave ecosystems on Earth for its research, Atri offers mechanisms through which life, if it ever existed on Mars, could survive and be detected in the future ExoMars mission (2022). submitted by the European Space Agency and Roscosmos. He hypothesizes that galactic cosmic radiation, which can penetrate a few meters below the surface, will cause chemical reactions that can be used to metabolize energy for survival, and host organisms using mechanisms seen in similar chemical and radiation environments on Earth.

“It’s interesting to think that life could survive in such a harsh environment, just two meters below the surface of Mars,” Atri said. “When the Rosalind Franklin rover is launched in 2022 on the ExoMars mission (ESA and Roscosmos), which is equipped with a ground drill, it will be well placed to identify current microbial life and hopefully provide some important insights.
