Scientists recommend that NASA "go deep into the depths" in search of an extraterrestrial life on Mars.
Experts believe there could be a better chance of finding living organisms beneath the surface of the red planet, and urge the space agency to start digging No evidence of life has been found on Mars.
Well, that's the view of Joseph Michalski, an associate professor of earth science at the University of Hong Kong who spoke with Live Science.
Michalski believes that humans are If we think that life must lurk on the surface of a planet, it is our own existence on earth.
When Mars was a young planet, he explained that its surface was very similar to Earth.
Eventually, however, the planet lost its magnetic field and exposed it to intense radiation that made life on the surface difficult.
Life on Mars may have already cooked before this happened, Michalski suspects and is simply adapted to life underground. [1
In fact, we have already seen plenty of evidence that lurks a lot of life in the depths of the Earth's biosphere.  According to Michalski, "deep-rooted microorganisms" account for nearly half of our entire life on our blue planet.
And this discovery could be transferred to Mars.
"We are at the point Now that there really is a limit to understanding what" deep biosphere "really means, and how this is related to exoplanets and other planets of our solar system, the professor explained.
" There is a window in our own origins. " Michalski believes that it is" even more habitable "on Mars than on the surface.
In fact, he suspects that the cooler core of Mars is even better suited for life than its own on Earth.
"We could have single organisms that could be inactive for a long time but could survive by metabolizing hydrogen, methane and possibly sulfur," he told Live Science.
"Without being too specific, we believe that there are many possibilities."  But under Mars Surfa ce is no easy task.
Due to the distance from Earth and Mars (about 33.9 million miles), exploring the fourth planet from the sun is difficult. That's why NASA uses satellites, probes, telescopes, rovers and lander to study the surface of Mars.
However, NASA has already begun investigating the subsoil with its InSight lander, which hit the planet in 2018.
One InSight's instruments are designed to dig 20 feet into the ground of Mars to measure the planet's temperature.
This should give scientists a better idea of whether the red planet can support subsurface life.
