Chapter 219 Hundreds of Iterations

The longest part of the asteroid is 89 kilometers, the widest part is about 40 kilometers, and the overall shape is a slightly curved hook.

In the star catalog compiled by the Itars, this asteroid also has no name, only a number.

However, Han Yang naturally does not intend to adopt the Itars' star catalog. He renumbered the asteroid and called it Star No. 2.

Star No. 1 is naturally Jade Star.

The probe launched earlier has shown that there are about 89 tons of gold and some other rare resources on this asteroid.

Because of the low total reserves, low quality, long mining cycle and difficulty, the Itars, including humans before the Itars came, have no interest in it.

But it is naturally different for Han Yang.

They have fallen to the point of relying on robbing Ceres to obtain supplies, so don't be dissatisfied with the poor quality and low reserves. It's good to have some mining.

Besides, isn't it just industrial capacity? The Itars find it troublesome, but I, Han Yang, have no shortage of industrial capacity.

What you don't want, I want, what you can't mine, I mine!

Under this circumstance, Cargo No. 1 went straight to Planet No. 2.

It has an acceleration of 0.8 meters per second squared. It will accelerate at this speed for a month, and the maximum speed will reach about 2070 kilometers per second. After that, it will immediately start to slow down, and when its speed drops to only tens of meters per second relative to the asteroid, it can just reach the vicinity of the asteroid.

The total voyage takes two months.

As for the return trip, Han Yang does not intend to let it return directly.

Two months passed in a flash. In the violent jet, Cargo No. 1 quietly stopped millions of kilometers away from Planet No. 2.

At this moment, it is not possible to approach it directly. Because there are also Itar probes around Planet No. 2.

Han Yang carefully manipulated the robot in the cargo ship, and also pushed out a large box, and then quietly approached it, and finally, like on Yu Shenxing, it also covered it.

In this way, Han Yang swaggered and unscrupulously operated the cargo spacecraft No. 1 to dock in the orbit of Star No. 2.

Next, it was mining.

Also in a canyon, Han Yang directly operated the landing spacecraft to go down, transported a batch of robots and a set of nuclear fusion reactor devices, as well as a batch of building materials, and began construction.

With energy and facilities, the construction progressed rapidly. However, the cargo spacecraft No. 1 did not stop here to wait, but set sail again and flew to Star No. 3.

Star No. 3 is larger than Star No. 2, with the longest point reaching 130 kilometers. According to previous detections, it has some heavy rare earth mines, in addition to some silver mines, copper mines and the like.

Silver and copper are not as scarce as rare elements such as gold and gallium, but they are also relatively scarce for Han Yang. Han Yang certainly did not let it go.

Following the same pattern, Han Yang once again released a large box to cover the Itar detector, and then released a set of nuclear fusion devices and base facilities again, and left again.

Then it was Star No. 4. On Planet No. 4, Han Yang controlled the Cargo No. 1 spacecraft to stay for a while longer. The main reason was that the fusion fuel of the Cargo No. 1 spacecraft was exhausted and had to be replenished here.

The route of the Cargo No. 1 spacecraft was planned in advance, and it was decided in advance to stay on Planet No. 4. Because Han Yang had detected before that there was more water ice on Planet No. 4. More water ice means more hydrogen. Although most of the hydrogen is protium, there will always be some deuterium, which is just right for fusion fuel.

Therefore, on Planet No. 4, in addition to the nuclear fusion power station and mineral smelting base, Han Yang also released an additional set of electrolytic hydrogen and deuterium gas purification facilities.

Under the black and gray earth of Planet No. 4, a large amount of hard water ice was collected in the cave.

That's right, whether it is Planet No. 2, No. 3 or No. 4, Han Yang still adheres to the concept when he developed Yushen Planet, that is, all mining operations must be carried out underground. All mining tasks must adhere to the most stringent environmental protection policies and must not change the geomorphic environment of the planet.

Only in this way can it be safe enough.

The mined water ice will then be melted by the heat of the nuclear fusion power station - it can be regarded as cooling the nuclear fusion power station, which is regarded as waste heat utilization. After that, it will be electrolyzed.

The protium-deuterium mixed gas produced by electrolysis is further centrifuged, and the relatively pure deuterium gas is produced and injected into the cargo spacecraft No. 1.

With the fuel replenishment, the exhausted cargo spacecraft No. 1 is revived again.

Leaving the facilities on Planet No. 4 to continue building the base and building a mineral smelting plant, the cargo spacecraft No. 1 went straight to the original Planet No. 2.

After this period of waiting, the base on Planet No. 2 has been built and mineral smelting has begun. At this stage, some materials have been produced, which is just right for the cargo spacecraft No. 1 to take back.

After running all the way, it finally arrived.

When it finally entered the orbit around Planet No. 2, the landing spacecraft also came to it with standard cargo boxes.

This batch of materials totaled about 5,000 tons. Among them, 260 kilograms of gold, more than 20 tons of copper, and more than 100 tons of tin were divided into 60 cargo boxes.

Cargo No. 1 returned half-loaded.

At this moment, Cargo No. 2, No. 3, and No. 4, manufactured by Han Yang, have also set sail and embarked on a journey to visit these asteroids.

They are loaded with nuclear fusion power station equipment and various industrial facilities. Like hens laying eggs, they release a batch of materials when they arrive at an asteroid, let them operate on the asteroid, and then immediately go to the next asteroid to lay eggs again.

They will not get some fuel supplies from the last asteroid until the equipment is released, and then return. When they return, they will also bring back the materials that have been produced by the first asteroid.

Under this circumstance, a large number of materials that are relatively scarce or extremely scarce on Yushenxing began to gather here continuously.

Han Yang's spirit became more and more excited.

"Finally, there is a stable channel for obtaining materials, and I no longer rely entirely on the supply of materials from the inner solar system. The shackles that restrict my performance have disappeared, and I can finally do a big job."

In the space around Yushenxing, docks appeared one after another, and in the end there were five.

These docks are specially used to build cargo ships of various tonnages.

As for small spaceships or combat spaceships, Han Yang plans to continue to adopt a modular construction method and not build a whole ship for the time being.

In this way, the ground base can be manufactured and the space dock is not needed for the time being.

Han Yang spent almost two years to build the original 100 cargo ships. At this moment, the asteroid farthest from Yu Shenxing, Star 153, was also visited by a cargo ship, releasing the fusion power station and other facilities, and began construction and production.

Han Yang does not plan to develop asteroids farther away. The distance is too far, and the transportation of materials requires a long journey, which is too time-consuming and not worth the loss.

At this moment, a total of 152 asteroids, with Yu Shenxing as the core, weave a large network. Each asteroid is a node of this large network.

There is at least one nuclear fusion power station on each asteroid, at least three different mineral smelting plants, more than six other plants, and at least 10,000 robots busy on it.

With the expansion of the mineral base, more robots are expected to work here in the future.

Under the cover of the asteroid's appearance, tunnels that extend in all directions gradually begin to appear inside the asteroid. They are like tree trunks hollowed out by pests. Their appearance still maintains its previous appearance, but their interior has already changed.

Han Yang's computing power radiates to these surrounding asteroids with the Yushen Star base as the core, and uniformly regulates and controls them, making them as if they have become one.

Each asteroid has different outputs, different distances, and different coordinates. Han Yang compiled an operation diagram, just like compiling a train operation diagram, combining the carrying capacity and speed of the cargo ships he built, as well as the material output speed of each asteroid, so that different spacecraft can run different routes and visit different asteroids. It can always make every spacecraft transportation, while using up the capacity as much as possible, just transport the output of the asteroids on the way during this period, consuming the least time and achieving the highest efficiency.

At this time, the materials from Ceres were about to be consumed. At this time, the asteroids began to produce on a large scale, and cargo ships came back one after another with full loads, and the material consumption was just connected.

In this vast space, in this place that is almost unnoticed by anyone, hundreds of cargo ships shuttle back and forth.

At this time, Han Yang's main energy was once again placed on the manufacture of modular spacecraft and the research and development of technology.

Smaller reactors with higher fusion efficiency, smaller and more reliable ion thrusters with greater thrust, more advanced electromagnetic guns and laser guns, more powerful interstellar mines and interstellar missiles, and satellites with wider detection range, more sensitivity, and higher survival rate, as well as the most important chip technology...

And so on, everything is within the scope of Han Yang's research and development.

The rebels in the solar system relied on such backward equipment provided by themselves to fight desperately with the Itars, attracting the attention and energy of the Itars and creating space and time for themselves to develop.

The looting of Ceres provided themselves with initial start-up funds, allowing them to develop surrounding asteroids and have a stable source of materials.

I must make good use of this time and go all out to develop, regardless of cost and consequences. Otherwise, when this strategic opportunity period is over, it is hard to say when the Itars will set their sights on the outer solar system.

By then, I really won't have a chance.

In the weapons test center, the electromagnetic cannon is roaring. In the propulsion experiment center, the new ion thruster is violently spraying light. In the computing center, tens of thousands of robots and intelligent machines are researching more advanced chip manufacturing technology.

At this moment, Han Yang's computing technology has reached the level of being able to produce 3-nanometer process chips in the laboratory, which is almost close to the limit of silicon-based chips. If it is manufactured on a large scale, it can already produce 5-nanometer process chips.

This has greatly improved Han Yang's computing power compared to the past.

Not only has his own computing power improved, but the computing power of the hundreds of secondary supercomputing centers he built has also been greatly improved, which has more effectively supported the construction and development of the Yushenxing base.

"The limit of silicon-based chips is 2 nanometers. I am almost approaching the limit. Now, it's time to develop a new generation of computing chips."

Han Yang thought secretly.

Once the silicon-based wafer process is smaller than 2 nanometers, the circuits will fail due to the quantum tunneling effect, rendering the wafer unusable. At this time, we can only develop new computing technology and find a new path.

Han Yang knew very well what that new road was.

Quantum computing.

Long before the arrival of the Eta people, human scientists had already conducted a lot of research on quantum computing, but they had never been able to make it practical.

The Eta people definitely have perfect quantum computer technology, but they will definitely not disclose it to humans. Even myself, a "good comrade" personally approved by Marundin, is unlikely to obtain relevant technology.

You can only rely on your own research.

"But I'm not in a hurry right now. I don't need to go all out on research and development. Just do preliminary research first. The most important task at this stage is to develop other technologies, such as advancement technology, fusion technology, and weapons technology."

Under such circumstances, a new generation of combat spacecraft manufactured in a modular manner was quickly produced, and soon enough parts were produced to assemble 100 ships.

Compared with previous combat spacecraft produced by Han Yang, their structures are more reasonable and their performance is more powerful. At the same time, the weapon system and armor defense capabilities have also been greatly improved.

"Well, this batch of spaceships should be supplied to the resistance forces in the Jupiter system."

Han Yang arranged for a cargo ship to deliver them, and then immediately began to develop a new generation of technology based on this batch of spacecraft.

"Based on previous development and construction experience, this batch of spacecraft may be able to improve armor defense to a certain extent."

Han Yang thought carefully and immediately controlled the robot to conduct experiments in the laboratory.

He planned to use some special process to give the spacecraft armor a certain degree of stress. In this way, once the external electromagnetic gun projectile breaks through the outer armor, the internal stress can be released immediately and annihilate each other with the kinetic energy of the electromagnetic gun projectile, thereby reducing its damage to the spacecraft armor and improving the overall defense.

"This idea is similar to the idea of ​​implosion armor, so it should be feasible."

Through special firing, bending and chemical processes, a plain steel plate is produced. Han Yang summoned a small electromagnetic gun and fired a projectile directly at it.

Under normal circumstances, electromagnetic gun projectiles with a speed of up to 300 kilometers per second will easily penetrate it. This was indeed the case during the test, and the steel plate was successfully penetrated.

But Han Yang was keenly aware that after penetrating the steel plate, the kinetic energy of the plasma mass transformed by the electromagnetic gun projectile was unusually weakened.

"Is it because of stress relief?"

Han Yang regained his energy, immediately collected data, conducted detailed research, improved the technology, and started testing again.

This time, when the electromagnetic gun projectile hit the steel plate, a violent flash of light suddenly erupted from the hit part of the steel plate, and the area around the blazing high-temperature impact point turned black.

But this time, the steel plate was not penetrated!

A thin layer of steel plate actually withstood the bombardment of electromagnetic gun projectiles!

"That's right. Although the stress is released now, and the next time it is bombarded, it will be unstoppable, but it has improved the ability to survive and resist attacks. Also, wait for me to improve the craftsmanship, increase the stress intensity, and reduce the area. , the ability to withstand attacks will be stronger.”

Now the stress of almost one square meter of steel plate has been released, and it has resisted an electromagnetic gun projectile. In the future, if the stress contained in one square centimeter of steel plate can withstand a projectile, assuming the surface area of ​​a spacecraft is 100 square meters, ideally, wouldn't this spacecraft be able to withstand the bombardment of one million electromagnetic gun projectiles? ?

In this way, the survivability will undoubtedly be greatly improved.

Han Yang was in high spirits and immediately decided to continue in-depth research on this road.

However, the technology currently mastered is enough to complete a technological iteration of the spacecraft.

In addition to armor defense technology, the electromagnetic gun's power, energy consumption, power, and nuclear fusion have all been more or less improved compared to the previous batch of spacecraft.

Han Yang unified it and used a full set of new technologies to produce 100 combat spacecraft again.

"This time supplied to the rebels on Saturn."

After this batch of spaceships were transported away, Han Yang resumed research and development of spacecraft-related technologies.

In addition to implosion armor, Han Yang also simultaneously began to develop another armor defense technology.

Active reactive armor.

The defense idea of ​​this kind of armor is actually very simple.

Han Yang specially developed a precision high-speed scanning radar and installed it in the armor of the spacecraft, allowing it to fully automatically monitor the outside of the spacecraft at all times under the control of a computer, paying special attention to the movements of small high-speed targets.

At the same time, Han Yang also developed a set of low-rate, low-power electromagnetic guns that can turn quickly.

What Han Yang wants to achieve is that once it detects that the electromagnetic gun projectile is approaching oneself, the electronic system will immediately calculate the trajectory and speed of the incoming projectile, and at the same time control one's own low-speed, low-power electromagnetic gun to launch projectiles for impact. Incoming projectiles.

It is not required to completely change the trajectory of the incoming projectile, as long as it can impact it slightly deflected.

Because compared to the vastness of space and the long distances between them, the target of a spacecraft is still too small. As long as the incoming projectile can be deflected even slightly, it will fail to hit the target.

However, the development of this technology caused Han Yang to encounter great difficulties.

No way, this technology requires too high performance from the radar - how easy is it to capture the trajectory of such small and fast electromagnetic cannon projectiles in real time?

Han Yang tried his best to develop this system, but in the last test, the comprehensive interception efficiency was only about 10%.

This is still under the premise that he used low-rate electromagnetic cannon projectiles as incoming projectiles. If it is replaced with a guard ship or even an Ita warship projectile, the interception rate will be even lower.

"But it's better to have it than not. Apply it first. In addition, there have been some updates in the ion propulsion and electromagnetic cannon technology during this period. If we integrate them, it can barely be regarded as another upgrade."

Han Yang produced another 100 warships based on these technologies and sent them to the inner solar system.

But this time, Han Yang did not adopt a modular manufacturing method.

At this stage, the spacecraft is too complicated to be simply assembled or disassembled, and can only be manufactured as a whole in the dock.

To this end, Han Yang also built two combat spaceship docks in advance, and specially modified several Hope cargo spaceships. Some steel bars were extended on both sides of their hulls, like a "Feng" character. These combat spaceships were hung on these steel bars and followed them to the inner solar system.

In the next generation of spaceships, Han Yang finally developed his own long-distance communication equipment, so it was another upgrade. When Han Yang developed a new sophisticated radar technology, it was upgraded again.

In this way, it was constantly upgraded. Various technologies related to spaceships, from hatch control to electromagnetic guns, were slowly improved at the speed of ants biting elephants.

Han Yang did not supply all these spaceships to the asteroid belt where the struggle environment was the most dangerous and difficult, although he knew that the rebel fighters there needed support the most.

He still adopted a dispersed approach, and did not let go of the four gas planets and the four rocky planets, truly achieving rain and dew.

Because Han Yang knew very well that even if all the spaceships he had built during this period were supplied to the asteroid belt, it would not change the environment there.

Because if there is a head-on conflict, the performance of their own spacecraft is still far from enough and can be easily annihilated.

However, if they are dispersed to other planets, the Itar people will have to divide their forces to defend and withdraw their forces in the asteroid belt back to their original planets.

The Itar fleet will also have to disperse its forces and even run around.

In this way, the pressure in the asteroid belt will be reduced and the situation of the rebels can be changed.

Under this circumstance, in about 20 years, Han Yang has built a total of 10,000 combat spacecraft and thrown them all into the inner solar system.

With 100 spacecraft as a batch, the performance of each batch of spacecraft will be improved compared to the previous generation of spacecraft - either thrust or endurance, not endurance or defense, not defense or reliability, not reliability or weapon system, or perception and detection capabilities, in short, there will always be room for improvement.

In these 20 years, Han Yang has iterated 100 times!

When Han Yang's work on improving the craft of the spacecraft finally came to an end, when he turned back to observe the situation in the solar system, he could clearly see that the solar system at this moment was already a raging fire, with smoke rising everywhere!

Every planet, whether it is a large planet, a dwarf planet or a satellite, and even in interstellar space, has traces of the activities of the rebel spacecraft everywhere!

The guard ships and the Itar warships attacked everywhere and put out fires everywhere.

Although the guard ships and the Itar warships were invincible, whenever they arrived at a place, the war there would subside, and the rebel warships would evacuate in a panic like a stray dog, and they did not dare to fight them head-on.

However, in more places where the guard ships and the Itar warships did not arrive, the rebels' resistance was in full swing!
