Zhang Xinghang was still immersed in the anti-load cabin, but at this time, the spacecraft formation had slowed down and switched to using ion engines as the main power.

Through the retina screen, he saw the star map around the spacecraft formation, although there are millions of asteroids in the asteroid belt, but in fact, the density of asteroids in the asteroid belt is not as large as imagined.

Just like the star map in front of Zhang Xinghang, in the range of 0.1 astronomical units in diameter, the number of asteroids appears sparse, and the asteroids marked in red are asteroids that cannot be mined by the government, and the rest can be mined.

However, not all mineable asteroids are unowned, and many have been marked in yellow, which means that the asteroid has been purchased by a private company, and the remaining asteroids that flash green are mineable.

The ones who can buy asteroids are all large companies, after all, after the purchase, if they don't mine, they will generate an idle tax of 1% of the total value of the ore star every month after three months, that is to say, if they don't mine after purchase, the idle tax can make the buying company bleed.

This is to prevent someone from maliciously applying for a large number of asteroids to hoard Juki.

Although there are millions of numbered asteroids in the asteroid belt, many asteroids with a diameter of less than 500 meters are mostly black households that are not registered, and these asteroids are Chang Dashan's targets.

There are many small companies doing this kind of gold panning in the sand, and so far, there are 3,764 space mining companies registered within the alliance, including more than 1,500 companies with mining licenses and mining spacecraft.

In less than ten minutes, Chang Dashan encountered two waves of mining spacecraft, which shows that there are not a few gold diggers in the asteroid belt.

The spacecraft's scanning equipment constantly monitors the surrounding asteroids, targeting iron-nickel asteroids or rock-iron asteroids with diameters of less than 500 meters.

For those asteroids with a diameter of less than 500 meters, only some iron-nickel planets or rock-iron asteroids are more valuable, and as for the ice asteroids with the largest number, unless there are rare elements or special minerals on them, the economic value is very low.

As for the two waves of mining spacecraft that have passed through here just now, why Chang Dashan still continues to explore this area, the main reason is that the accuracy of the civilian detection system is not high, and for those asteroids with a diameter of less than 100 meters, they need to get close to about 500 kilometers to be discovered.

This leads to the phenomenon of incomplete prospecting, plus the asteroid itself is flying at all times, and the position of the asteroids in the entire asteroid belt changes all the time, maybe there were no asteroids here an hour ago, and there are an hour later.

[Big mountain, have you found any valuable asteroids?] Zhang Xinghang asked.

[Not at the moment, but three of them were normal, all of them were of the Ice and Earth type.] Chang Dashan replied as he looked at the detection system.

Zhang Xinghang also understands the current situation of this industry to some extent, asteroid mining requires more or less luck, many people may not be able to touch a valuable asteroid for ten days and half a month, and some people will encounter a valuable asteroid as soon as they enter the asteroid belt.

If you encounter a mineable asteroid as soon as you enter the asteroid belt, it will be really profitable, obviously this is not an impossible thing, and space mining is risky.

In the case of low-speed cruise, the spacecraft formation can operate in the asteroid belt for more than ten days, of course, provided that the living materials are fully prepared.

The prospecting work spaceship was boring, and after Zhang Xinghang looked at the navigation log, he no longer paid attention to this matter, but browsed the network information of Blue Star through the quantum communication system.

[Oceania Daily: The Council of the Alliance held a global ecological conservation conference in Tokyo, and decided that in the next 10 years, all marine fishing within the alliance will be cut, and the waters within the alliance will be completely banned from fishing, and Antarctica and nearby waters and the Arctic Ocean will be mandated as nature reserves, and any exploitation of natural resources and excessive commercial development in the protected areas is strictly prohibited...... ］

Zhang Xinghang looked at the news, in fact, he is very supportive of this bill, the demand for meat within the alliance can now be solved by artificial meat and imitation natural farming, and there is no need for marine fishing.

For example, the alliance has recently diverted some young fishermen to work as ocean patrol officers, while many fishermen over the age of 60 have been forced to undergo genetic enhancement and re-education, which is a major trend within the alliance, and the genetic enhancement and re-education of the elderly can re-energize social productivity.

After genetic enhancement, the life expectancy of human beings has increased to the limit of 450 years, and now 100 years old is not a teenager, 100~200 years old is youth, 200~300 years old is the prime of life, and 300~450 years is old age.

That is to say, after the strengthening, the alliance is generally composed of teenagers and a small number of young people, and this terrible increase in the life expectancy of the whole people has brought a new impetus to the development of the alliance.

In fact, the re-education of the alliance is very hot now, and the learning ability of the genetically strengthened people is very terrible, and the ability to remember is standard.

Zhang Xinghang's parents went to participate in re-education training after being genetically strengthened, and it seems that after decades of fighting in the shopping mall, his father was also tired, and he chose to study cosmic astronomy and nuclear physics.

After watching the news for a while, Zhang Xinghang also entered a holographic classroom, and he himself was also studying, the alliance not only has the knowledge of human civilization, but also the knowledge of the Anluo civilization and the Sosi civilization.

The engineering, mechanics, physics, mathematics, silicon-based life sciences of the Soth civilization, and the genes, viruses, environmental modification, quantum communication, and biological computers of the Anluo civilization.

This is very fortunate for human civilization, when it is not strong, it encounters a civilization seed ship, a declining wandering civilization, and they can just be used by human beings and become the nourishment for human beings to thrive.

Zhang Xinghang took the courses of nano-atom smelting, quantum communication, and the history of Soss civilization, which are unique to human beings.

[Mr. Zhang, good news, an iron-nickel asteroid with a diameter of 20~30 meters has been discovered. Chang Dashan excitedly reported the news.

Zhang Xinghang, who had just taken two classes, had to quit the holographic class, and his attention was once again focused on the spaceship.

[Is it an unowned asteroid?] Zhang Xinghang hurriedly asked.

[I've checked, and there's no planetary encoder on it, it's an unowned asteroid.] Tokoyama returns.

[Then get ready to mine!] Zhang Xinghang happily commanded, he didn't expect that he would meet a good start when he went out for the first time.

Providing a holographic projection model, he saw that the asteroid looked a bit like a capsule, with a length of about 34 meters, a width and height of 18~20 meters, and a total volume of about 8,400 cubic meters, which was a typical iron-nickel asteroid.

A worker bee-class mining spacecraft approaches the "capsule asteroid", and lasers cut the planet into blocks of 1 cubic meter.

Zhang Xinghang looked at the information fed back by the detection system, and he suddenly smiled, the density of this capsule asteroid is 4.9 tons per cubic meter, and the mass of the entire asteroid is about 42,000 tons.

It not only contains common iron-nickel elements, but also has a fairly high content of lithium and zinc elements, and after a comprehensive evaluation, it is estimated at 440 yuan per ton of ore, and the asteroid is worth about 18 million.

In the asteroid belt, wealth and opportunity spur countless mining ships to search here and there, hoping to become the lucky one who gets rich overnight.
