In space, a huge fleet of 667 spaceships gallops freely like arrows from the string, and their destination is: the asteroid belt. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The asteroid belt is a dense area of asteroids in the solar system between the orbits of Mars and Jupiter, which has been counted by more than 120,000 asteroids that have been numbered, and 98.5% of the asteroids have been found here. Since this is the region with the highest concentration of asteroids, estimated to number as many as 500,000, this area is known as the main belt, commonly known as the asteroid belt.

Some astronomers believe that, according to gravitational calculations, it seems that the asteroid belt should not be a group of asteroids, but a complete planet. Therefore, there is such a saying in the scientific community: it was the Big Bang of the tenth largest planet in the solar system that decomposed into tens of millions of asteroids hundreds of millions of years ago, forming an asteroid belt, and the mass of the small planetary belt at this time should be 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 equivalent to the earth, but due to the disturbance of the gravitational force of the sun and Jupiter, most of the material has been thrown out, and the residual 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 more than the third cosmic speed, which can get rid of the shackles of the sun's gravity and enter the wider universe from the solar system.

Scientists define the average distance between the Earth and the Sun as 1 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 a space area of about 2.0 astronomical units from the Sun. At a speed of 110 kilometers per second, it can only advance 009.5 million kilometers per day, about 0.064 astronomical units, which is as slow as a snail crawling in the background of the universe, but the spacecraft can still accelerate all the time, and according to the results of supercomputer simulations, it can enter the asteroid belt in about 27 days.

However, don't think that you can encounter countless asteroids at any time when you enter the asteroid belt, on the contrary, it is difficult to encounter.

The reason is very simple, although there are a lot of asteroids and meteorites in the asteroid belt, there are more than 120,000 asteroids that have been numbered, and the number of small gravel like a few centimeters and millimeters must be an astronomical number, but the "belt" of the asteroid belt is about 200 million kilometers wide, which is larger than the distance from the earth to the sun, so the density of material in the asteroid belt is pitiful. Several probes launched by the United States have passed through the asteroid belt unharmed, and these probes have no defense capability at all. According to calculations, in the asteroid belt, the probability of a probe colliding with an asteroid is less than 1 in a billion.

However, although the probability of collision with an asteroid or meteorite in space is very low, there are times when you encounter it.

After the fleet flew for more than three hours, the artificial intelligence on each spacecraft suddenly sounded a warning sound: "Warning, warning! An asteroid was found ahead, about 107 meters in diameter and 670,000 kilometers away, just in the direction of the spacecraft." ”

670,000 km, which sounds far away, but at the current speed of the fleet, that is, a distance of more than an hour. If the spaceships of this fleet only have the technical level of the United States, it must urgently adjust the flight direction to avoid this asteroid, however, this fleet is equipped with electromagnetic railguns and has an energy shield, which can be completely rigid to boost morale!

"Spacecraft 7, Spacecraft 11, Spacecraft 12, Spacecraft 16, Spacecraft 23, ready to launch railguns to destroy asteroids. ”

In a "Tiangong 2nd Generation" spaceship, Yang Rui calmly gave an order.

The "Tiangong-level" spacecraft is a spacecraft designed by the state itself, and since entering space, the country and the future technology company have been "separated", basically playing their own games. The future technology company designed the "star-class" spaceship, the country also designed the "Tiangong-class" spaceship, and the current most advanced is the "Tiangong 2" spaceship, 4.3 kilometers long, 1.2 kilometers wide, is a hideous steel monster.

As for Yang Rui, he is the commander of this fleet, and the spacecraft of the future technology company must also obey his command. This is also a helpless thing, since the formation of the fleet, there must be a unified command, or it will be chaotic, and the future technology company is too shallow, the talent reserve in the space field is not enough, the country can draw excellent pilots from the air force, the talent almost as many as you want, and better than the future technology company talents, like Yang Rui is one of the leaders, the Air Force Major General was born, flight experience, combat experience, command experience is extremely rich, the future technology company can not find a comparable one.

However, as time goes on, the team of future tech companies will also get stronger and stronger, and the situation will definitely improve.

Spacecraft 12 and Spacecraft 16 are the "Star 2" of Future Technology The spacecraft, after receiving Yang Rui's instructions, immediately applied to the artificial intelligence on the spacecraft to open the permission of the electromagnetic railgun, and the artificial intelligence immediately sent the information of the permission application to the moon through the communication equipment on the spacecraft, and finally, this information was transmitted to Beidou, Beidou understood what happened in an instant, approved the permission application, and transmitted the relevant information back to the spacecraft. In fact, Zhang Wei can also authorize, but the company now has hundreds of spaceships, and it will increase to thousands, or even tens of thousands, in the future, if he personally handles these things, then there is no time to invent at all, therefore, he is all handed over to Beidou to be responsible, with Beidou's ability, even if tens of thousands of permission applications are received in one second, they can be quickly processed.

The fleet flew forward for another 57 minutes, and Yang Rui gave the order: "Spacecraft No. 7, spacecraft No. 11, spacecraft No. 12, spacecraft No. 16, spacecraft No. 23, prepare to launch the railgun, count down to ten seconds." Ten...... Nine...... One...... Launch!"

"Boom!"

The spaceships that fired the electromagnetic railguns all trembled slightly, and a muffled voice echoed through the spacecraft.

The warhead, which weighs 23 kilograms, has a speed of 37 kilometers in discharge, and in addition to the initial velocity of the spacecraft itself, the real speed at which the warhead flies out of the railgun reaches a terrifying 165 kilometers per second! Such a speed, placed on the earth, is absolutely devastating!

"It is expected that in 19 minutes, the shells will destroy the asteroid in front of us, but you should continue to be vigilant. ”

Yang Rui's voice was calm and waveless, as if what he wanted to destroy was just a gadget, not an asteroid that could hit the earth and destroy humanity that had once made humans fear.

19 minutes later, 30 shells carrying terrifying energy, suddenly hit the asteroid with a diameter of about 107 meters, under the gaze of the fleet, this relatively large asteroid instantly shattered, countless fragments flew out at a terrifying speed, some even reached hundreds of kilometers per second!

"All ships, activate the energy shield!"

Yang Rui saw this scene more than 40,000 kilometers away through the equipment, and calmly gave orders.

Although these fragments are small, they can also destroy the spaceship instantly when they hit the spaceship, and the energy shield can protect the spaceship well. Of course, there is an upper limit to the power of the energy shield, and if it collides with the asteroid just now, the energy shield will not be used.

Three minutes later, the fleet and some of the asteroid fragments collided head-on, and then, these fragments collided with the energy shield, further shattering into smaller fragments, and the spaceship, unharmed, calmly passed through the debris field!

"Yay!"

It was the first time for many astronauts to experience this kind of event, and they immediately cheered, this is the power they have mastered, an asteroid with a diameter of 107 meters, and if you say destroy it, you will destroy it! With this experience, they are full of confidence in the next mission!

"Whew!"

Yang Rui also breathed a sigh of relief, he had dealt with many similar incidents in simulation training, but in reality, it was the first time!

He sighed in his heart, "This is the power of science and technology, although human beings are small, but with their own wisdom, with the science and technology they have mastered, they are already qualified to stand on the universe!" (To be continued.) )
