On the morning of August 18, Beijing time, it is reported that the grand goal of human landing on Mars is exciting, but due to many scientific and technological limitations, it still stays in the imagination of science fiction. At present, American scientists have invented a technology to make oxygen on the surface of Mars, and NASA is confident that this dream can be realized in the 1930s.

▲ scientists have invented a new plasma-based technology that can generate and separate oxygen in the Martian environment, creating living conditions for future human landings on Mars.

It is reported that one of the main obstacles to human landing on Mars is the lack of sufficient oxygen. with the unremitting efforts of scientists, a new technology based on plasma has been developed, which can generate and separate oxygen in the Martian environment. The system can not only play a key role in the development of life support systems, but can also be used to process fuel, building materials and fertilizers on Mars.

Mars is the fourth planet in the solar system from the sun, the red planet is "near death", the surface is covered with dust, cold climate, desert and wasteland everywhere, and the atmosphere is very thin.

After years of survey and analysis by scientists, in fact, Mars is not silent, it is a dynamic planet with seasons, polar ice caps, canyons and extinct volcanoes, and there is evidence that Mars was more active in ancient times. Mars is one of the most explored planets in the solar system, and it is also the only planet to launch a rover to explore. Mars takes a little more than 24 hours a day, and a year is equivalent to 687 earth days.

The Martian atmosphere is mainly composed of carbon dioxide, which can be broken down to produce oxygen and carbon. However, researchers from the University of Lisbon in Portugal, the Massachusetts Institute of Technology in the United States, the University of Sorbonne in France, the Eindhoven University of Technology in the Netherlands and the Netherlands Institute of basic Energy say there are two major obstacles to oxygen production on the Martian surface.

▲ the system can not only play a key role in the development of life support systems, but can also be used to process fuel, make building materials and fertilizers on Mars.

Dr Vasco Guilla (Vasco Guerra) of the University of Lisbon, author of the study, said: "first, it is necessary to break down carbon dioxide molecules to extract oxygen, which is in fact a very difficult molecule to decompose; second, the separation of oxygen from a mixture of gases such as carbon dioxide and carbon monoxide is a very complex process. We are considering implementing these two steps in a holistic way and addressing both technical challenges at the same time, and plasma can give full play to its advantages. "

Plasma is the fourth natural state of matter, and the other three are solids, liquids and gases, which contain freely charged particles, such as electrons, which are light in mass and can easily accelerate to a very high energy state in an electric field.

"when bullet electrons collide with carbon dioxide molecules, they can directly decompose into carbon dioxide molecules or transfer energy to cause them to vibrate, and this transfer of energy can be converted to carbon dioxide decomposition to a large extent," Guilla said. Our experiments with our colleagues in France and the Netherlands have proved that this theory is valid. "

He also pointed out that in addition, the heat generated by the plasma is also conducive to the separation of oxygen, and the oxygen generated by the plasma technology may be a key link for human immigrants to create a breathable extraterrestrial environment, at the same time, it can also be used as a basis for the production of fuel and fertilizer, enabling human settlers to grow crops on the Martian surface and solve food problems.

Plasma technology also has a lot of room for application on Earth, researchers say. It can make green fuels and recover chemicals by separating carbon dioxide molecules. It can also help solve the problem of climate change on Earth. The study was conducted ahead of the completion of NASA's Artemis 1 mission, which is scheduled to be launched on August 29 to lay the foundation for future missions to the moon and Mars.

The atmosphere of ▲ is mainly composed of carbon dioxide, which can be decomposed to produce oxygen and carbon, but based on traditional technology, it is difficult to extract oxygen directly from Martian carbon dioxide.

According to NASA, the Artemis-1 lunar exploration mission is an unmanned flight test, which will provide a practical basis for future human deep space exploration, and the mission will prove the commitment and ability of human space exploration. it will help to expand human living space to the moon and more distant planets.

It is understood that if the Artemis I mission is successful, NASA will launch astronauts to Mars in the late 1930s or early 1940s.
