Chapter 334: Attack

In space, a huge fleet of 667 spaceships such as the arrow of the off-string, galloping freely, their destination is: the asteroid belt.
The asteroid belt is a dense area of ​​asteroids between the orbits of Mars and Jupiter in the solar system. It has been calculated from more than 120,000 asteroids that have been numbered. 98.5% of the asteroids are found here. Since this is the densest area of ​​asteroids, with an estimated number of 500,000, this area is therefore called the main belt, usually called the asteroid belt.
Some astronomers believe that, according to the calculation of gravity, what appears in the asteroid belt should not be a group of asteroids, but a complete planet. Therefore, there is a saying in the scientific community that the Big Bang, the tenth largest planet in the solar system, decomposed into millions of asteroids, forming an asteroid belt, and the mass of the small row belt at this time should be It is only a small part of the original asteroid belt. According to the results of computer simulation, the original mass of the asteroid belt should be comparable to that of the earth. However, due to the gravitational disturbance of the sun and Jupiter, most of the material is thrown away and remains. The quality is only about one thousandth of the original.
After continuous acceleration, the fleet's speed has reached 110 kilometers per second, which has far exceeded the speed of the third cosmos. It can get rid of the sun's gravity and escape from the solar system into a wider universe.
However, compared to the vast universe, this speed is still too slow. Scientists define the average distance between the earth and the sun as one astronomical unit, which is approximately equal to 149.6 million kilometers, and the average distance of Mars from the sun is 1.5 astronomy. Units, the asteroid belt is within the space area of ​​about 2.17-3.64 astronomical units from the sun. At a speed of 110 kilometers per second, it can only advance 0.095 billion kilometers per day, about 0.064 astronomical units, placed in the background of the universe, just as slow as a snail crawling, but the spacecraft can continue to accelerate, according to supercomputers The results of the simulation can enter the asteroid belt in about 27 days.
However, don't think that you can encounter countless asteroids at any time after entering the asteroid belt. On the contrary, it is difficult to encounter.
The reason is very simple. Although there are many asteroids and meteorites in the asteroid belt, there are more than 120,000 asteroids that have been numbered, and the number of small crushed stones like a few centimeters or a few millimeters is definitely an astronomical number, but the asteroid The belt is about 200 million kilometers wide, which is larger than the distance between the earth and the sun. Therefore, the density of the asteroid belt is small. Several probes launched by the United States all passed through the asteroid belt unharmed, and these probes had no defense at all. According to calculations, in the asteroid belt, the probability of collision between the probe and the asteroid is less than one part per billion.
However, although the probability of collision with an asteroid or meteorite in space is very low, there are also occasions.
After the fleet flew for more than 3 hours, the artificial intelligence on each spacecraft suddenly issued a warning sound: "Warning! Warning! An asteroid with a diameter of about 107 meters and a distance of 670,000 kilometers was found in front of it, just in front of the spaceship. The way forward. "
670,000 kilometers, it sounds very far away, but at the current speed of the fleet, it is more than an hour away. If this fleet of spacecraft has the technical level of the United States, it must definitely adjust the flight direction urgently to avoid this asteroid, but this fleet is equipped with an electromagnetic orbital gun and also has an energy shield, which can be completely rigid. To boost morale!
"Spacecraft 7, spacecraft 11, spacecraft 12, spacecraft 16, and spacecraft 23 are preparing to launch orbital guns and destroy asteroids."
In a "Tiangong II" spaceship, Yang Rui calmly gave orders.
The "Tiangong class" spaceship is a spaceship designed by the state itself. Since entering the space, the state and the future technology company have "separated", basically playing each one separately. Future Technology Company designed the "Starry Sky" spacecraft, and the country also designed the "Tiangong Class" spacecraft. The most advanced one is the "Tiangong II" spacecraft, which is 4.3 kilometers long and 1.2 kilometers wide. A fierce steel monster.
As for Yang Rui, it is the commander of this fleet, and the spacecraft of the future technology company must also obey his command. This is also impossible. Since the fleet is formed, there must be a unified command, otherwise it will be messed up, and the future of the technology company is too shallow, the talent reserve in the space field is not enough, and the country can recruit excellent pilots from the Air Force. There are almost as many talents as you want, and they are better than the talents of future technology companies. For example, Yang Rui is one of the leaders. The major general of the Air Force is born. His flight experience, combat experience, and command experience are all very rich. The future technology company ca n’t find it. To be comparable to it.
However, with the passage of time, the future of technology companies will become stronger and stronger, and this situation will definitely improve.
Spacecraft 12 and Spacecraft 16 are the "Star II" spacecraft of Future Technology. After receiving the order from Yang Rui, they immediately applied to the artificial intelligence on the spacecraft to open the electromagnetic orbital gun, and the artificial intelligence immediately passed through the universe. The communication equipment on the spaceship sent the permission application information to the moon. Eventually, this information was communicated to Beidou. Beidou understood the course of the matter in an instant, approved the permission application, and sent the relevant information back to the spaceship. After a set of procedures is completed, astronauts on the spacecraft have the authority to use the electromagnetic rail gun. In fact, Zhang Wei can also be authorized, but the company now has hundreds of spaceships, which will increase to thousands or even tens of thousands in the future. If he handles these things himself, he will have no time to invent, so he All are handed over to Beidou. With Beidou's ability, even if tens of thousands of permission applications are received in one second, it can be processed quickly.
The fleet flew forward for another 57 minutes. Yang Rui issued an order: "Spacecraft No. 7, Spaceship No. 11, Spaceship No. 12, Space Ship No. 16, Space Ship No. 23, ready to launch an orbital gun, count down ten seconds. Ten ... Nine ... One ... …emission!"
"boom!"
The spacecraft that fired the electromagnetic orbital gun all shuddered slightly, and a deep voice echoed inside the spacecraft.
A warhead with a weight of 23 kilograms and a firing speed of 37 kilometers, plus the initial speed of the spacecraft itself, the true speed of the warhead flying from the rail gun reached a terrible 165 kilometers per second! Such a speed, placed on the earth, is absolutely ruined!
"It is expected that after 19 minutes, the shells can destroy the asteroid in front, but you must remain vigilant."
Yang Rui's voice was calm and waveless, as if all he wanted to destroy was a gadget, not an asteroid that once worried humanity that could hit the earth and destroy humanity.
After 19 minutes, 30 artillery shells carried horror energy and suddenly hit an asteroid with a diameter of about 107 meters. Under the watch of the fleet, this relatively large asteroid instantly shattered and shattered. Flying around, some even reached hundreds of kilometers per second!
"All spaceships, activate the energy shield!"
Yang Rui saw this scene that happened more than 40,000 kilometers through the equipment, and gave orders calmly.
Although these fragments are small ~ EbookFREE.me ~, they can also destroy the spacecraft in an instant by impacting on the spacecraft, and the energy shield can protect the spacecraft very well. Of course, the power of the energy shield has an upper limit. If it collides with the asteroid just now, the energy shield will not be used.
After 3 minutes, the fleet and some asteroid fragments met head-on, and then these fragments hit the energy shield, further fragmented into smaller fragments, and the spacecraft, unharmed, calmly passed through the debris zone !
"Yay!"
Many astronauts experienced this kind of event for the first time, and they immediately cheered. This is the power they have. An asteroid with a diameter of 107 meters, said to destroy it! With this experience, they are full of confidence in the next task!
"call!"
Yang Rui also breathed a sigh of relief. He handled many similar events in simulation training, but in reality, it was the first time!
He sighed in his heart, "This is the power of technology. Although human beings are small, with their own wisdom and with the technology they have mastered, they are already qualified to stand on the universe!" (To be continued.)
