People are about to turn Mars into colonies?

A few months before his death in December 1996, the famous American astronomer Cark Sagan recorded a hopeful message to future Mars explorers: 'Whatever the reason you set foot What is going on to Mars, I'm glad you were there. And I wish I could go with you. '

Seventeen years later, the Dutch company Mars One has launched a project to turn Sagan's dream of setting foot on Mars. Mars One plans to take four astronauts to the Red Planet to establish a human 'colony' on it.

These 4 people will be the first group to permanently settle on Mars in 2023. After that, 4 more people every 2 years on this planet.

However, this plan has encountered some great difficulties. First, we have to mention gravity. When on Mars, the human body will have to adapt to gravity just by 38% of the force on Earth. It is thought that this will cause the body to change some things such as bone density, muscle strength and blood circulation. Once transformed to adapt to Mars, people will no longer be able to survive in Earth's condition. The second difficulty is directly related to the first difficulty. It is the astronauts who have to say goodbye to the whole family of friends because the journey to Mars is a no return.

The website of the Mars One company said, it is impossible to predict or hope to have a trip back to Earth. If they want to go back, they will need a fully fueled rocket, capable of escaping the Mars gravitational field; Sufficient conditions are needed to survive the 7-month journey to Earth. And the ship that takes them back must be able to connect to a space station around the Earth or can make a safe landing. Mars One emphasized: Each of the above conditions is not simple, requires not much technical ability, money.

But according to Mars One's medical director, Norbert Kraft, the company's Mars project attracted 10,000 people "applying" via phone messages. Mr. Kraft said the number of candidates to date is between 18 and 62, including women, although men are the majority.

The reason they want to Mars also seems to be. A 32-year-old American woman named Cynthia said that going to Mars was her childhood dream when she was taken by her mother to listen to astronomer Sagan preaching at the University of Wisconsin and had the opportunity to talk to him. about Mars.

However, Mars One's primary goal is to find someone over the age of 18 with persistence, adaptability, curiosity, trustworthiness and resourcefulness.

Mars One has developed a feasible roadmap and a financial plan for the project based on existing technologies. According to them, this mission is fully feasible. The basic elements needed for life are available on the red planet. For example, water can be taken from ice on the surface of Mars. The planet also has nitrogen, which accounts for 78% of the Earth's atmosphere. And energy will be taken from specially designed solar panels.

In March, Mars One signed a contract with the US Paragon Space Development Group to take the first steps in developing a life support system and spacecraft for this project.

The project will cost about 6 billion USD. The Mars One hopes that some of it will come from broadcast royalties on the trip. It is predicted that the event of settling on Mars may be the world's largest press event.

However, the project received a lot of skepticism and concern about how humans exist on Mars and their health. According to Dr. Veronica Bray of the Planet and Moon Laboratory of the University of Arizona, Earth is protected by strong magnetic fields in the solar wind. Without this strong magnetic field, it is difficult for humans to exist. She analyzed further: The surface of Mars is very harsh. Without liquid water, atmospheric pressure is no different from vacuum, high radioactivity and large temperature difference. High radiation may increase the risk of cancer, reduce the immune system and potentially cause infertility.

To reduce radiation, settlers will first have to dig a few meters of soil to make shelter below and shelter the property with special equipment.

Mars One hopes that the project to settle on Mars can inspire generations to believe that everything is possible and nothing is beyond human reach.
