Can live on mars

Live in mars

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 Mangalyaan in 2018 itself. 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 definitely aroused enthusiasm, but the practical situation is that everything has to be carried here from the air and water and radiation is so terrible due to the proximity to the sun that the imagery of staying for two-four days is deep. 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 calculations, 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 such deep digging device has been sent to Mars yet, but even X-ray spectrography can be done.

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 destroyed its geomagnetism, the water flew 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.

Keep in mind, so far, only six missions have been successful in landing a rover vehicle on Mars, and all of these have been operated by the US government body NASA. A European Space Agency (ESA) vehicle was damaged just before it landed on Mars. Later it was discovered that one of his retro rockets, which reduced the speed of the vehicle due to a slight disturbance of the calculation,

Was stopped just half a second ago. As a result, the ESA vehicle fell shattering from the height of just a two-storey building. Earlier, Russia had successfully landed one of its vehicles on Mars, but it lost contact with the earth just 14 minutes after landing on the surface.

These failures point to a difficult problem. Tuning of sensitive telecom equipment becomes very difficult due to the distance of Mars and Mars changing continuously in the long gap of 556 million to 40 crore 10 lakh kilometers and when the sun comes in between the two. Even if there is no obstacle in the middle, it takes several minutes to reach Mars from Earth. At the same time, it takes time to know whether the instruction has been implemented or not. In the middle, there was the cover of the sun, then for several days, the contact of the vehicle on the surface of Mars completely breaks with the Earth.

Some things should also be done on the difficulties related to sending manned vehicles on Mars, which is being discussed a lot here. The first is that the window to send a vehicle opens only after 26 months. No matter how much science can progress, it will not change. The reason is the same. Changing distances between the two planets. If you want, then within ten to fifteen days, many of the vehicles will leave for Mars, but the next convoy will leave only after 26 months. More time to reach? 115 to 180 days. American entrepreneur Elon Musk says that it can be reduced to one month in the future through advance technology. Till then, a four-five-month unilateral space trip can kill humans with radiation. In the International Space Station, it can be prepared only to an extent, because the Earth's magnetic field is shielded and protects it from solar storms.

However, if you reached Mars by purchasing a ticket worth crores of rupees, then you will feel less than a third of your weight there. There are 75 kg adults here, then they will move like a 25 kg child. Oxygen for breathing and water for drinking will be there to some extent, but like the 'martian' movie, give up the dream of growing potatoes and spinach. Nitrogen is more important than everything else for root plants, which is just two percent in the atmosphere of Mars, compared to 78 percent of the Earth. The day there, that is, the time between one sunrise to another sunrise is about forty minutes longer than ours. Although the year is almost double our year. The permanent weather on the center of Mars is also colder than the polar regions of the Earth, but if it is hot enough, it becomes like winter in Ladakh. In between, the sandy storms are so fierce that very strong houses have to be built to avoid them.

Elon Musk has rightly said that early Marsatris must first answer the question, 'Are you ready to die? With food to stay alive for nearly two years, water for emergency and oxygen, strong camp to stay together, when you reach this desert planet in the afternoon and in the morning and evening in the dark black sky, only your curiosity and livelihood will be there. Only she will keep you alive. Do not expect any help from the earth, because apart from a few broken messages from here you will not get anything. Excluding the rest of the expenses, Musk has reported only two million dollars in rent, although enthusiastic entrepreneurs of the United Arab Emirates have expected it to be $ 20,000 by 2117. Keeping the challenges in mind, the proposal of Mangal Yatra would seem childish at first glance, but what would be better if it could raise an expectation of an alternative life in a world surrounded by fears of pandemics, religious turmoil and nuclear destruction?
