When you consider Mars, also known as the Red Planet, frigid temperatures, thin air and harsh radiation are the first conditions that come to the mind. The scientists believe that these conditions are the reason why there has been no existential life on Mars detected.
Had there be any sort of life on Mars, it would have to deal with extremely harsh radiation. Yet, the scientists have not given up on the possibility of finding life on Mars and are digging up the soil to find any traces of it.
LIFE OF MARS
Mars shares a lot of similarities with Earth along with sharing proximity. This is the reason why scientists have been trying to find evidence of life on Mars. They need to recognise life signs on Mars because it would uncover more secrets about the universe. It would also tell whether or not the varied life forms can be hazardous to humans. To eliminate any such chances of human risks, scientists are investigating more deeply into the matter.
The Curiosity rover has already unveiled a lot of things about Mars and now the scientists are trying to examine more. In a situation where the scientists are aiming to colonise Mars by 2030, it becomes more important to see the challenges posed for living things.
Mars is said to have lost its magnetic field billions of years ago which made the solar wind destroy the planet’s atmosphere. Owing to the erosion of atmosphere, the planet’s surface was affected by the harsh radiation. Mars appears to be the early form of planet Earth.
It has been already proved that during ancient time, Mars had liquid water on its surface and might have supported life forms. In 2016, there was a discovery of a huge chunk of underground ice of Mars in its Utopia Planitia region.
In 2017, the Curiosity rover helped the scientists in the detection of boron on Mars. Boron is a vital ingredient for life on the Earth. This strengthens the possibility of habitability of Gale Crater on the Mars.
Even though extremophile lichen could survive for 34 days in Mars Simulation Laboratory, there is no evidence shown for its reproduction, evolution and sustainability in the Martian environment. This is the reason why the scientists are looking for the signature of life on Mars. So far, there has been no evidence supporting or denying the possibility of life on Mars.
