Construction of immigrant base

With the continuous development of human space science and technology, many countries have been able to launch space probes. For example, Israel, China and the United States successfully launched a Mars probe this summer. The purpose of human exploration of extraterrestrial planets is to find a livable planet and then establish an immigration base on it. At present, Mars is promising. Before establishing a base on Mars, human beings need to establish a base on the moon, because the base on the moon can be used as a transit point for human beings to land on Mars.

The natural environment of the moon and Mars is not suitable for direct living, so human beings need to build bases on these two planets that can resist harsh environmental conditions. Many scientists have put forward various design schemes. According to reports, research teams from the University of Bologna and the University of Padua in Italy investigated and analyzed the lava pipelines under Mars and the moon, and finally concluded that these lava pipelines are the best choice for human construction bases.

How did the research team find lava tubes on the moon and Mars?

Researchers from the University of Bologna and the University of Padua found the linear structure on the surface of the moon and Mars from the high-definition images taken by the planetary probe, which reminded them of the lava tubes on the earth. Long ago, geologists discovered the existence of lava tubes in Hawaii, Australia and other areas. After long-term research, human beings have understood the formation and characteristics of lava tubes on the earth. So after seeing the linear structure on the surface of the moon and Mars, they immediately reacted that there might be a hollow structure underground.

So the researchers collected a large number of detection data about the surface of Mars and the moon, and then used these data to build a digital terrain model. Through this model, the researchers found that there are indeed structures similar to lava tubes in the underground of the moon and Mars. In order to further prove this speculation, the researchers scanned the inside of the lava tube on the Galapagos Island on the earth with laser, and then compared the scanning results with the digital model, which improved the possibility of lava tubes on the moon and Mars.

What are the characteristics of lava tubes on the moon and Mars?

After initially determining the existence of lava tube, researchers began to estimate the lunar lava tube by using the latest method, and found that the widest part of the lunar lava tube reached about 300 meters and the length exceeded 40 kilometers, which was enough to accommodate a small space base. A similar situation exists in the lava tubes of Mars. The lava tubes of Mars and Moon are much larger than those of Earth, with stable structure and open space.

The biggest feature of these lava tubes is that they are underground and can shield almost all cosmic radiation, so if humans build their bases in lava tubes, they don't have to worry about space radiation at all. Why are the Moon and Mars smaller than the Earth, and the lava tubes they form are larger than the Earth? The researchers explained that this is because the gravity of the moon and Mars is weaker than that of the earth, which leads to their limited influence on the flow of molten slurry, so the molten slurry can obtain a larger flow range.

The discovery of lava tubes provides a new choice for human beings to build immigrant bases.

Although it is still a long time before human beings begin to build lunar bases and Mars bases, many scientists have begun to imagine where to build what kind of bases. Due to the harsh natural environment of the moon and Mars, many raw materials cannot be directly used as building materials, so some people propose to print out the materials needed to build the base with 3D printing technology. It has also been suggested that the base be made into a honeycomb shape to resist meteorites and radiation.

If the latest research conforms to the actual situation of the moon and Mars, that is, there are lava tubes with open space under both planets, then human beings will save a lot of trouble on the road to building interstellar immigration bases. It is understood that the European Space Agency and some European universities have jointly launched a special astronaut training program, which will train astronauts who can move in underground caves, and the training place will be selected in the lava tube on Lan Sarot Island, which shows that the lava tube has become a choice for mankind in the future.
