Earth's outer space is very lively.

Thanks to the possession of anti-gravity spaceships, the cost of traveling between humans and space has been reduced to the extreme, and the large size of anti-gravity spaceships can transport large equipment, instruments, parts and components, etc.

Therefore, in just a few years, all kinds of man-made space buildings have bloomed everywhere in space, like a spring breeze blowing across the earth, and a hundred flowers are vibrant.

The number of satellites is so large that it is difficult to count, and sometimes there are more than a dozen satellites in an important orbit, with the same speed, direction, etc., but evenly distributed in orbit.

There are many enterprises with private satellites and global positioning and navigation around the world, and satellites that were once unattainable have entered 'thousands of households'.

Space station, almost all powerful countries have built huge space stations in space, as for the former International Space Station, it has long been lowered to the sky over the Pacific Ocean, burned out in the friction between speed and air.

Tiangong Space City, Galaxy Science and Technology City, Huaxia Space City, Huaxia Mining United Space City, Huaxia Space Energy United Space City, Huaxia Space Agriculture United Space City...... The huge space cities belong to large and small units, institutions, enterprises and so on in China.

In addition, there are also space castles built by some world powers, such as Uncle Sam's 'Bald Eagle Castle', the Japanese 'Yaki Orochi', the Indians' 'Sun Palace', and the Polar Bear's 'Kremlin'.

Although these are also hung with the name of the space station, they are no different from a huge space castle, and they have a lot of functions.

Scientific experiments, space observation, space ports, lunar mining transit, space business transit, etc., play a very many roles, and each space city is a huge complex.

Only some weak countries, and with great ambitions in the field of space, can only lease some anti-gravity spacecraft of other countries to build some space stations similar to the previous International Space Station.

But even so, these stations are still very large, much larger than the International Space Station.

Satellites, space stations, space cities, and in addition to the vast space, there are also huge space solar power stations.

At present, the space solar power generation industry is almost monopolized by Chinese enterprises, because of the large-scale popularization and promotion of private anti-gravity vehicles, the world's power has become more and more tight.

In such a situation, the profit of the space solar power station is very considerable, and the capital that tastes the sweetness is desperately expanding in space in a few years.

One after another, huge space solar power stations are built in the sky, the scale is larger than the other, like a huge space field, and the solar panels are constantly absorbing the sun's rays and converting them into huge electricity.

The development of space farms is also very rapid, and the advantages of space agriculture have greatly made up for the shortcomings of agriculture in space, under the management mode of science, science and technology, and mechanization.

A huge space farm often needs only one person to manage, and the output of vegetables, grains, etc. is enough to exceed the output of tens of thousands of acres of land on the ground, which is incredibly efficient.

Thanks to the large-scale development of space farms, China has also begun to implement large-scale policies such as returning farmland to forests, lakes, and grasslands.

In many regions, there is no longer agricultural production, and of course this is not a random implementation, because of the rapid economic development in recent years, it is difficult for traditional agriculture to continue.

There are fewer and fewer people engaged in agriculture, and there are more and more barren fields in the vast rural areas, so it is just the right opportunity to take advantage of this opportunity to upgrade and integrate agriculture.

The entire outer space of the earth, although the air space is very large, is now almost occupied by all kinds of space objects of human beings.

As far as the eye can see, no matter which direction you look, you can see a large number of space buildings, as if in the sea next to a beautiful coral reef, a variety of marine life is roosting freely.

The earth is this beautiful coral reef, and the various space structures created by humans are the marine creatures that inhabit the coral reefs.

In addition to these massive space buildings, there are also huge anti-gravity spaceships, and spaceships are constantly coming and going in space.

The price of anti-gravity spacecraft is too expensive, so these scientists abroad have also come up with their own ways to use their own spaceships in space.

These spaceships use conventional propulsion technology, and although they cannot travel to and from Earth, they can only fly between buildings in space.

However, it can also greatly save the use of anti-gravity spacecraft, and transport and carry a large number of materials and personnel in space.

These spaceships have become the mainstream of transportation in outer space on Earth, and there are a lot of them, and even many domestic enterprises, companies, and institutions in China also like to use this kind of spaceship.

Because this kind of spaceship is generally relatively small, it is very convenient and simple to moor in the space port and space castle, and there is no need for a special berth.

I have to say that human wisdom is infinite, as long as you can have cheap tools to travel to and from space, this is in space, and human thoughts begin to fly constantly.

Not only between outer space, but also between the Earth and the Moon.

Foreign scientists have also developed a new tool, a large spacecraft, a spacecraft using traditional rocket thrust, which can only fly in space, and there is no way to land on the earth and the moon.

This kind of spacecraft has a very strong transportation capacity, and undertakes a large part of the transportation of materials between the earth and the moon, but because there is no anti-gravity engine, it is not as safe as an anti-gravity spacecraft, and it has to be slowed down for a long time in advance every time, and the transportation speed is far inferior to that of anti-gravity spacecraft.

At this time, one after another anti-gravity spaceships took off from the ground into space, and these anti-gravity spaceships were branded with the logo of Galaxy Technology Group.

Among the first anti-gravity spaceships, Wu Renjie looked at the bustling space, and he couldn't remember how many times he had been in space.

As the first batch of astronauts recruited by Galaxy Technology Group, in just a few years, he has traveled back and forth to space, and to and from the Earth and the Moon hundreds of times.

He was the first person to mine on the moon, starting the era of lunar mining, and the rock he brought back is now in the Lunar Mining Museum.

This time, he once again took on the role of commander-in-chief of the construction of the space factory in space.

"Time flies, but the world changes faster."

Wu Renjie's eyes couldn't help but start to turn back time.

A few years ago, Wu Renjie was eliminated as an Air Force pilot in the astronaut selection, and at that time he was extremely eager to go to space.

Later, he was recruited by Galaxy Technology Group to become one of the first astronauts of Galaxy Technology Group, and after just a few months of training, he went into space and became an astronaut.

He still clearly remembers the first time he flew into space, at that time the outer space of the earth was still very empty, deserted, there were no space buildings at all, the only International Space Station and Tiangong space station that could be seen, as for the small satellites, although there were many of them, it was difficult to see.

At that time, the moon was very deserted, and it was difficult to find the breath of human beings except for the footprints left by Armstrong.

However, just a few years have passed, and it feels as if centuries have passed for Wu Renjie, and the development is really space.

Wu Renjie couldn't help but take out his camera again to take pictures of everything in front of him, this is a habit he maintains, every time he travels back and forth to space, he will do so.

In the past, his dream was to be able to walk and take a look in space, but now, Wu Renjie feels that he is probably inseparable from space in his life, and the dream in his heart has become to go to a broader sea of stars to take a walk and take a look.

Anti-gravity spaceships continued to fly out of the earth one after another, and the anti-gravity spacecraft led by Wu Renjie flew towards the Lagrange point between the earth and the moon.

The Lagrangian point is a relatively magical point, which is the five special solutions to the restrictive three-body problem in celestial mechanics. A point in space where a small object is gravitationally pulled by two large objects, at which the small object remains essentially stationary relative to the two large objects, is called a Lagrangian point.

Theoretically, there are 5 Lagrangian points between any two massive objects, but only 2 of them are stable.

The space factory that Qin Yi wants to build is very huge, far beyond these space castles, space farms, etc. in outer space on the earth, so it is necessary to be very cautious in site selection, and a sufficiently stable point must be selected, and the Lagrange point between the earth and the moon is the most ideal point.

Of course, this is because the speed of anti-gravity spaceships, spaceships, and so on is too slow, and space buildings in space cannot be separated from the earth, so this must be done.

If the speed of the spacecraft is fast enough, the entire solar system is so large and the space is so vast that you can choose at will.

But not now, in the absence of a fast enough spaceship, the transportation of materials will become a problem, not to mention that compared to the vast universe, even the entire solar system, human beings are still just beginning.
