In space, a huge fleet of 667 spaceships, such as a flying arrow, gallops freely. Their destination is the asteroid belt.
Asteroid belt is a dense area of asteroids between the orbits of Mars and Jupiter in the solar system. According to the statistics of more than 120000 asteroids, 98.5% of them have been found here. Because this is the most dense area of asteroids, estimated to be as many as 500000, this area is called the main belt, usually called the asteroid belt.
Some astronomers think that according to gravity calculation, what appears in the asteroid belt should not be a batch of asteroids, but a complete planet. Therefore, there is a saying in the scientific community that the explosion of the tenth largest planet in the solar system billions of years ago broke down into tens of millions of asteroids and formed the asteroid belt. At this time, the mass of the asteroid belt should only be a small part of the original asteroid belt. According to the results of computer simulation, the original mass of the asteroid belt should be the same as that of the earth, but because of the sun and Jupiter The gravitational disturbance, most of the matter is thrown away, the remaining mass is only about one thousandth of the original.
After continuous acceleration, the speed of the fleet has reached 110 kilometers per second, which is far faster than the speed of the third universe. It can get rid of the shackles of the solar gravity, and get out of the solar system into a broader space.
However, compared with the vast universe, the speed is too slow. Scientists define the average distance between the earth and the sun as one astronomical unit, which is about 149.6 million kilometers, while the average distance between Mars and the sun is 1.5 astronomical units, and the asteroid belt is within the space area of 2.17-3.64 astronomical units. At the speed of 110 kilometers per second, it can only advance 0.09 billion kilometers per day, about 0.064 astronomical units. Placed in the background of the universe, it is as slow as a snail. However, the spacecraft can accelerate all the time. According to the results of supercomputer simulation, it can enter the asteroid belt in 27 days.
However, you don't think you can meet countless asteroids at any time after entering the asteroid belt. On the contrary, it's very difficult to meet them.
The reason is very simple. Although there are so many asteroids and meteorites in the asteroid belt, there are more than 120000 numbered asteroids, and the number of small debris like a few centimeters or millimeters must be an astronomical number, but the asteroid belt is about 200 million kilometers wide, larger than the distance between the earth and the sun. Therefore, the density of material in the asteroid belt is small Poor. Several probes launched by the United States have all passed through the asteroid belt without any defense capability. According to the calculation, in the asteroid belt, the probability of collision between the probe and the asteroid is less than one billionth.
However, although the probability of collision with asteroids or meteorites in space is very low, there are also times.
After more than three hours of fleet flight, the artificial intelligence on each spaceship suddenly issued a warning sound: "warning! Warning! An asteroid with a diameter of about 107 meters and a distance of 670000 kilometers was found in the front, just in the direction of the spacecraft
670000 kilometers, it sounds very far away, but at the current speed of the fleet, it's more than an hour's distance. If the spaceship of this fleet is only of American technical level, it must be to adjust the flight direction urgently and avoid this asteroid. However, this fleet is equipped with electromagnetic orbital gun and energy shield, which can be hard and rigid to boost morale!
"Spaceship 7, spaceship 11, spaceship 12, spaceship 16, spaceship 23, ready to launch orbital guns and destroy asteroids."
In a spaceship of "Tiangong generation 2", Yang Rui calmly gave orders.
"Tiangong class" spaceship is a spaceship designed by the state itself. Since its entry into space, the state and future technology companies have "separated" and basically played their own games. The future technology company has designed the "star class" spacecraft, and the state has also designed the "sky class" spacecraft. At present, the most advanced is the "sky class 2" spacecraft, which is 4.3km long and 1.2km wide. It is a ferocious steel monster.
As for Yang Rui, who is the commander of this fleet, the spaceship of future technology company should also follow his command. There is no way to do this. Since we have formed a fleet, we must have a unified command. Otherwise, it will be a mess. In the future, science and technology companies have a shallow foundation, and the talent reserve in the space field is not enough. The country can select excellent pilots from the air force, and there are as many talents as it wants, and they are better than the talents of future science and technology companies. For example, Yang Rui is one of the best Major general of the air force has rich experience in flight, combat and command. There is no future technology company that can match it.
However, with the passage of time, the team of technology companies will become stronger and stronger in the future, which will definitely improve.
Spaceship 12 and spaceship 16 are the "Star 2 generation" spaceships of the future technology company. After receiving Yang Rui's instruction, they immediately applied to the artificial intelligence on the spaceship for the permission to open the electromagnetic orbital gun, while the artificial intelligence immediately sent the information of permission application to the moon through the communication equipment on the spaceship. Finally, this information was transmitted to Beidou, where Beidou is located In a flash, I learned the process of the event, approved the permission application, and sent the relevant information back to the spacecraft. After this process, the astronauts on the spacecraft have the permission to use the electromagnetic orbital gun. In fact, Zhang Wei can also authorize, but the company now has hundreds of spaceships, which will increase to thousands or even tens of thousands in the future. If he deals with these things himself, he will have no time to invent them. Therefore, he has all given Beidou the responsibility. With Beidou's ability, even if he receives tens of thousands of permission applications in one second, he can quickly handle them.
The fleet went ahead for another 57 minutes, and Yang Rui ordered: "spaceship 7, spaceship 11, spaceship 12, spaceship 16, spaceship 23, ready to launch the orbital gun, count down to 10 seconds. Ten... Nine... One... Launch! "
"Boom!"
The spacecraft that launched the electromagnetic orbital gun all trembled slightly, and the low sound echoed in the spacecraft.
The weight of the warhead is enough to have 23 kg, and the muzzle velocity has reached 37 km. In addition to the initial velocity of the spacecraft itself, the real velocity of the warhead flying out of the orbital gun has reached a terrifying 165 km / S! Such speed, put on the earth, that is absolutely destroying the sky and destroying the earth!
"It's estimated that in 19 minutes, the shell can destroy the asteroid in front, but you should keep your vigilance."
Yang Rui's voice is calm and wave free, as if it is just a gadget to destroy, rather than an asteroid that once worried mankind that could hit the earth and destroy mankind.
19 minutes later, 30 shells carrying terrifying energy suddenly hit an asteroid with a diameter of about 107 meters. Under the eyes of the fleet, this relatively large asteroid suddenly broke up. Countless pieces of debris flew out at a terrifying speed, some even reaching hundreds of kilometers per second!
"All ships, start the energy shield!"
Yang Rui saw this scene happening more than 40000 kilometers away through the equipment, calmly giving orders.
Although these fragments are small, they can destroy the spacecraft in an instant when they collide with the spacecraft, and the energy shield can protect the spacecraft very well. Of course, the power of the energy shield is limited. If it collides with the asteroid just now, the energy shield will not work.
Three minutes later, the fleet and some of the asteroid debris hit each other, and then they collided with the energy shield, further breaking into smaller pieces, while the spacecraft, safe and calm, passed through the debris zone!
"Yeah!"
Many astronauts experienced this kind of event for the first time, and immediately cheered up. This is the power they have. An asteroid with a diameter of 107 meters said to destroy! With this experience, they are full of confidence in the next task!
"Whoo!"
Yang Rui is also relieved. He has dealt with many similar events in simulation training, but in reality, it is the first time!
"This is the power of science and technology," he said in his heart. "Although human beings are small, they are qualified to stand in the universe with their own wisdom and technology." (to be continued. )
