Can live on mars, just have to .

This extraordinary time is going on to explore the fourth-ranked planet Mars in order to move from within to outside in the solar system. This year, the spacecraft of the United States, China and the United Arab Emirates, orbiting Mars, are sending information continuously orbiting it. This list may also include our own Mangalyaan, which ISRO had said last February to correct and send data continuously. However, something worth releasing the news was last heard in 2018, quoting Mangalyaan. The American vehicle Percerence has been on the surface of Mars for two and a half months, while a small two-kilogram small helicopter Ingenuity with powerful camera has been flown on this alien planet in the last fifteen days. China's rover is also looking for a place worth landing for three months. Its news can come anytime from the middle of May to the end.
Why is there so much violence about Mars?
Mainly for three reasons. For one thing, apart from the earth, the only place inhabited by humans is going to be none other than this in the next thousand years. The news of water on the moon has certainly aroused enthusiasm, but the practical situation is that everything has to be carried here from air and water and radiation is so terrible due to its proximity to the sun that the imagery of staying for two-four days is a deep one. Can be done only in caves or in cells with very special designs. However, the moon is a better place for robots. A person's visit to and from there will be good only for things like planning and coordination. In contrast, Percision has just done a few days ago to make oxygen from the thin air of Mars and the water is seen coming out at every landing site there, even though it has to be a lot of effort to make it drinkable.
The second reason is the search for life on Mars, which according to the calculation, seems almost impossible. Keep in mind, the distance of Mars from Earth always changes. Its minimum measurement has been recorded to be 56 million km, while the maximum measurement can go up to 40 crore 10 lakh km. Staying so far away, it is still a far-fetched thing for us to say any sure thing about whether there is life on Mars or not. But if there is life and its nature is as cell based as that of life on Earth, then its presence should be at least 25 feet below the surface, given the radiation on Mars. We can expect that if the soil extracted in a very packed state by digging 25-30 feet deep can be brought to the earth, then we can encounter very old, archaea-grade dormant bacteria from its investigation. No digging device so deep has been sent to Mars,
The third reason is to understand the evolution of the Earth through the study of Mars. There are four epochs of development of the Earth, which Ion has a tendency to say. Keep in mind, the age of the Earth was measured at 4 billion 54 million years and its first era ends some four billion years ago, i.e. about 60 crore years after the Earth was formed. In this era named Hydian, the initial 120 million years are without the moon and no form of life is beyond imagination. The end of this era is believed to have coincided with the rise of early forms of life on earth. Based on these creatures, this era, which lasted about one billion years, was named Archean era. Even there is no big difference in planetary history of Earth and Mars. Rather than being away from the sun than the earth, there is a possibility of developing life there quickly. But in the middle of the Archean era, the two worlds separated.
The assumption about the Earth is that certain varieties of bacteria have transformed the planet to the current form by creating oxygen through photo-synthesis, while large meteorites on Mars have destroyed its geomagnetism, caused water to blow up and the atmosphere. The dilution became almost insignificant. A major objective of the scientists behind the study of Mars is to test their concepts about the initial nature of the Earth. In this, the biggest screw is associated with finding some form of life on Mars or its archaeological remains. What are the things responsible for being near or failing on a planet in terms of life? Whether life was born anywhere other than Earth or not, and if it was born anywhere else, like Mars, then why is the phenomenon of its survival being recorded only on Earth?
In the investigation related to all these questions, Perseverance has done a very important work and it has all the necessary materials and fuel to do this work with full capacity for the next two years. It has collected a lot of samples from the surface to the bottom by digging two meters. The data sent by Perseverance about the disappearance of water shows that this work was not done in one stroke. A prolonged drought, then a humid climate for some time, then a drought again, and then several episodes of moisture are reflected in its sent pictures. Details about the destruction of magnetism are yet to be revealed, although there are relatively more arrangements for its study in the Chinese Rover.
