PS: Thank you for your support!

On Mars, it is undoubtedly quite difficult to carry out large-scale construction on the surface because of the environmental problems on the surface, especially because of the extreme storm on the surface here.

Not to mention how expensive the various raw materials required for large-scale construction are to transport, and even if they are actually built, they may not be able to live in them.

The daily red sandstorms here are extremely fast and mixed with large amounts of iron particles, and once swept down, they are extremely strong grinding wheels that can grind and polish the surface of buildings.

If it is an ordinary reinforced concrete building, it will not take two days after it is completed here, and the strong storm will polish all the edges and corners of the appearance to be extremely rounded, and in less than a week, the appearance of the reinforced concrete structure will be cut into pieces of round depression visible to the naked eye, and the thickness of the wall will be reduced by a few centimeters, and even the steel bars in the wall will leak out, and then it will be polished and polished by the storm, and the polished will shine, as if it has just been freshly baked, and it may even be hot.

Such a building, which cannot be maintained on the surface of Mars for a year, will be thoroughly worn through and worn out, and will move infinitely closer to the flat surface of Mars.

Therefore, if you want to build a house on the surface of Mars, unless you build a high-strength alloy house, it is not reliable, and even if you build an alloy house, it may not be comfortable to live in.

After all, a house is for rest, even if you live in a solid and reliable alloy house. But all day long, I listened to the grinding sound of iron sand and alloy houses outside. It's as noisy as a construction site. The roar of cutting steel bars is loud, even if the house is soundproofed, I am afraid it will be uncomfortable to sleep.

Especially considering that the number of humans living on Mars in the future is not a small number, even in a short period of time, and the long-term accommodation requirements of such a huge number of cutting-edge talents determine this residential project. It is necessary to meet a certain high standard and a high level of comfort.

In addition to the furniture and equipment required for general family life, the environment and ecological construction that meet the public's aesthetics are also needs that must be taken into account.

After all, the large-scale population on Mars, their life on Mars, is not a day or two, not a month or two months, and the harsh environment in a short period of time, maybe it is still feasible to overcome it a little, but. If you settle a large population for a long time, the environment is harsh. It is undoubtedly difficult to retain talent.

Even if short-term migrants are forced by organizational pressure and choose to bear silently, this will undoubtedly greatly affect the efficiency of these staff, and fundamentally speaking, the gains outweigh the losses.

Therefore, large-scale construction under the surface has become the only reliable and most feasible solution.

Under the surface of the earth at a certain depth, a large amount of underground space has been opened up, and after the underground space has been sealed, with the help of the vast underground space environment here, it can not only create a huge, safe and comfortable underground living space, but also form an air environment suitable for human life in the sealed environment, and carry out large-scale ecological transplantation.

With the scientific and technological level of modern society, in a certain scale of environment, through scientific regulation, real-time analysis and adjustment of various elements in the environment, forming a semi-natural and semi-artificial underground ecological environment, this is not unimaginable, but a completely feasible way.

In this way, not only does it avoid the huge trouble of building on the surface of Mars, but also the overall ecological environment construction will also minimize the cost of simulating the living environment in the living space.

Although it is also difficult to excavate a shallow underground space suitable for a large number of people, this difficulty is undoubtedly too difficult compared with the large-scale construction of underground buildings.

What's more, anyway, in the future of the Mars geomagnetic activation project, the underground engineering that should be dug will also be dug after all, combining the two major projects to form an integrated engineering scheme, that is, the use of the earthworks required in the excavation process of the Mars underground magma power station, and greatly reduce the cost of living for residents, which is undoubtedly a double thing.

Anyway, the people who carried out Martian immigration at the beginning were only a few parts, and in a short period of time, there was no need for a huge space similar to the planetary environment, so the underground space construction was carried out first, and a huge Martian underground space was artificially opened up, and in the Martian underground space, an underground artificial ecosystem was established to form a quasi-natural ecological environment, and after this kind of natural ecology formed a certain scale, large-scale migration to Mars was officially started, and the progress of the entire Mars project was accelerated。

Such a Mars development plan is the general development direction of the implementation route of the Mars project organized by the earthlings.

Since the large-scale construction plan of Mars engineering began around 2035, today, after more than ten years of construction, the entire underground building complex of Mars has formed an incomparably huge scale, and the permanent population of Mars alone has broken through the 100,000 mark, and countless materials are sent to the Mars base by a steady stream of clouds every day to support the large-scale construction of the Mars base.

Although after more than ten years of high-intensity construction, the surface of Mars seems to have almost no major changes except for some large-scale space stations in high-altitude orbit, but in fact, huge changes have occurred below the surface of Mars.

On a carefully selected lowland plain, in the midst of the endless red soil, huge man-made structures have begun to rise.

These man-made structures are relatively low and open, slightly protruding from the ground, and the shape looks like a huge circular platform.

As can be seen on the surface, these platforms are used for entry and exit to and from the Martian underworld, and large-scale material entry and exit are all entered from these platforms.

Aside from these alloys, which are used to pass in and out of the material, there are few traces of man-made structures on the surface of Mars. Some earthworks and rocks are transported to the surface on a large scale during underground excavations. It has long been swept away by the winds that rage on the surface of Mars from time to time. Almost evenly distributed to all sides of the Martian surface.

Because the air quality on Mars does not meet the needs of human beings, there are not many air exchange facilities above the surface, only a few large gas exchange hubs, which occasionally emit some excess air gas components to the outside world, but on the contrary, some air components for industrial purposes are extracted from the Martian air more often.

Aside from these few surface structures, there is no sign of manifies on the surface of Mars.

But if someone is able to build along those small amounts of surface as the midline. If you cut through the underground world of Mars and take a closer look, you will find that this is already an incomparably large underground world jungle.

The layers of the underground world, the height of each layer, are tens of meters high, and one after another huge underground cavities are connected to each other like sugar gourds, forming the basic style of the underground world.

In such an underground world, the scale of each layer has a huge size of more than ten square kilometers, and similar underground space. Now there are more than a dozen layers.

In these huge underground worlds, there is a connection between the layers. It is connected by an extensive transportation network.

In the underground space of each floor, houses, factories, residential areas, commercial areas, entertainment areas, and all kinds of humanistic living environments are readily available.

In addition to these social environments, there is also a three-dimensional ecosystem that is deliberately managed.

In this large underground ecosystem, in addition to the soil quality is native to Mars, including hundreds of beneficial bacteria and decomposing bacteria living in the soil, earthworms burrowing in the soil, various bees, ants and other insects on the surface, all kinds of lichens, fungi, weeds, a large number of plants in the vine woody grasses, as well as various small organisms and small animals stocked in the natural ecology, it can be said that each of them is transferred from the earth's native area.

More than 10 years of Mars construction time, from the beginning of a few people, living in a ground station, relying on the earth to transport supplies little by little, operating remote control construction robots, began to dig to the Mars underground, and then to a piece of industrial machinery and equipment was transported and installed to Mars, a simple underground factory was established, a variety of Martian self-produced resources were used, until now, hundreds of thousands of employees stationed on Mars, forming a huge industrial complex, in accordance with the established construction plan of the Mars project, constantly moving forward and forward。

During this period, a large number of industrial chains have been copied and rebuilt on Mars, and many daily necessities and industrial raw materials have been developed in Mars, although more than 100,000 Martian residents, all kinds of living needs, resource needs, are still more than 90% still need the input of local resources, but relying on the self-reliant development of the Martian industrial chain, it still greatly reduces the amount of local resource supply on the earth.

You must know that the long distance of space cargo leads to the cost of every gram of foreign materials imported here, which is as high as several hundred yuan, and the living and production needs of 100,000 people are also a huge expense for the earth civilization.

However, due to the lack of population, resources and equipment on Mars, complete import substitution is still far away, but some simple production links, such as agricultural production, self-sufficiency in grain and vegetables, have reached a very high level, which is a great relief for the pressure on transportation and supply on the earth.

In addition to agriculture, there are some of the simplest basic industrial manufacturing field development, Mars is now the most important development direction, is the recycling of various materials, at this point, Mars has reached a peak, all kinds of materials transported on the earth, all worn, damaged items, have been recycled, without a little waste, which is undoubtedly much stronger than the recycling industry on the earth that is still slow to progress.

However, these things are all side jobs, and the various manpower and material resources used on Mars are less than one-third at most, and more personnel are still used in various engineering construction, infrastructure development, base operation and maintenance, and continuous underground expansion of the Mars base.

More than a dozen Martian underground spaces with a large number of people are just the most important living spaces today, and under these living spaces, there are even more vast and boundless underground spaces.

For example, under the underground living space, up to dozens of floors of new living space have been roughly opened up, the main underground space framework, the decoration and improvement of the underground space, the construction of some residential buildings, etc., have been roughly completed, and a large number of people are busy in these new living spaces, all kinds of support and maintenance systems, the staff of the base operation system, are in accordance with the requirements of the overall plan, continue to improve these spaces, carry out the construction of various ecosystems, etc., every day is a busy mess。

Mars is a large base with an increasing population, and the average annual population has been increasing in the past few years, and now it has reached the point of adding tens of thousands of new residents a year, so the new living space must be prepared in advance, and all kinds of supporting projects are ready before the new staff will be equipped.

So, just to cope with these upcoming new job migrants, several new underground living spaces have to be created in the Mars base every year.

In addition to the dozens of new living spaces that are still being improved, there are also underground spaces that are several kilometers deep under this huge Martian base.

These underground spaces, at the deepest level, are far less complete and safe than the inhabitants that have been opened up and reinforced.

The depth has reached the most cutting-edge underground engineering part of the underground engineering several kilometers underground, which is the most important development direction of the entire Mars project, and it is also the most dangerous place, where some of the most core machinery and equipment in the Mars base are concentrated, and it is also the most high-tech job.

Advanced geological detector, with a strong underground detection function, can provide the most urgently needed underground environmental data for the progress of the project, mining efficiency is amazingly powerful underground mining robot, once fully started, can even dig hundreds of meters deep underground every day, but, although the equipment is advanced, but in this deep underground structure, it will collapse at every turn. Water seepage, the staff can only catch up with the progress little by little, while working to strengthen the roadway, the advance into the deep underground is extremely slow, and the powerful equipment is often difficult to work at full strength.

It can be said that the entire Mars project has been advanced little by little, full of hardships and difficulties.

But this is the future of civilization on Earth, and the Martian immigrants, each of whom is not afraid of hardships and dangers, fights at his post. (To be continued.) )
