Life On Mars Is Not Habitable Due To The Presence Of Toxic Martian Soil

The soil present on Mars contains a harmful chemical called perchlorate which can make human survival on this planet difficult.

The scientists are planning to make the survival of human life on Mars habitable. One of the recent reports suggested that we have only a few years left on Earth and people may have to find another planet which is habitable.

Many of the researchers were not used to think that after Earth, Mars is the potential planet which can support the life on it. But the new research study conducted by the researchers from the University of Edinburgh says that the Martian soil has the presence of the toxic chemical compound which can make the survival of human life difficult. The deadly chemical compound present in the Martian soil kills the organic life when they are hit by the UV rays of the sun.

The harmful chemical is known as perchlorate which is also found in deserts present on Earth but the concentration of this chemical is comparatively low. The scientists have already started cultivating crops on Mars to make life habitable on it. One of the studies conducted by Phoenix Lander in 2008 discovered this harmful chemical substance called perchlorate.

The presence of perchlorate and its harmful effects was studied by the researcher by simulating the same environment on Earth using short-wave UV simulation. The effect of this chemical reaction was studied on the bacteria called Bacillus subtilis. The perchlorates chemical immediately killed the bacteria. If this chemical comes in contact with the iron oxides and hydrogen peroxide the bacterial death is increased by multiple times.

Hence it was proved that the Mars may not be habitable as it seems to be. As the Earth is largely affected due to the UV rays that strike the surface of Earth. These harmful UV rays are blocked by Ozone layer but a decrease in the ozone layer exposes this planet to harmful rays. The same scenario is seen on the surface of Mars as the Martian surface is hit by the harmful UV rays and there is limited ozone layer.

Further study is needed to determine the impact of perchlorates on other organic matter. The results of the study also do not indicate that the Mars is completely inhabitable and will not all sustain the life on it.
