Four Hundred Interference

The two space shuttles set sail one after another. In the following month or so, the media paid close attention to the aircraft on the long-distance voyage day and night. From the history of the aircraft to the refitting technology, from the equipment on board to the identity of the crew, the two space shuttles were exhausted. The space shuttle makes a comprehensive report, real-time speed and position, and is the top priority of the report, which is broadcast almost every day like the weather forecast. Please read the most complete!

During the reporting interval, the major TV stations invariably inserted the basic knowledge of astronomy, and hundreds of millions of human beings, for the first time, seriously understood the sky above them.

Although electromagnetic propulsion is more suitable for long-distance voyages than traditional propulsion, the thrust of electromagnetic propulsion is not high, but it does not require chemical fuel. After 22 days of flight, Earth finally arrived at the distance of more than 2.7 million kilometers from the earth. The scheduled launch location is more than five times the distance between the Earth and the Moon.

In the minds of ordinary people, the launch site of the two spacecraft should be a certain point in the universe, or a certain position that is relatively stationary relative to the earth, but in fact, the spacecraft that arrived at the designated location is still accelerating.

After the Earth was in place, it immediately began to adjust its position, aiming the electromagnetic gun at the distant space, instead of the asteroids flying head-on!

The asteroid group is flying towards the earth at a high speed of more than 30 million kilometers away, and the flying distance is as high as 1.38 million kilometers every day. The position can't be used for anything. It is necessary to aim at a certain point in front of the asteroid's orbit and launch at a precise azimuth and speed, so that it is possible to approach the asteroid.

Be careful, it's approaching, not hitting!

In fact, the major countries on the ground and the astronauts in the air are very clear that no matter how accurate the electromagnetic gun is, in space where the distance can be calculated in tens of millions of kilometers, the spread area of ​​the ammunition will be very large, and even all shells may be The point of falling short.

Not to mention the asteroid group, even if it hits the earth 2.7 million kilometers away, it is hard to say how many shells will hit. The reason why ordinary projectiles are replaced with missiles is to consider the accuracy of the hit.

These missiles are all special models urgently produced. The missiles are extremely short and carry very little fuel. The process exploded by mistake.

Several of the missiles do not carry nuclear warheads, but carry the equipment needed to detonate them.

The space on the Earth is limited, and there are only more than 300 missiles on board. The two astronauts used electromagnetic guns to launch the missiles on the spacecraft one by one in a few days. Every time they launch, they must carefully adjust the shooting angle.

When all the ammunition is empty, the speed of the spacecraft also drops a lot due to the recoil, but due to the inertia, the spacecraft still flies head-on towards the asteroid group. Don’t tell me that the electromagnetic gun has no recoil.

Of course, the spacecraft does not have to slow down and return. If the position of Venus is suitable, it can also fly to Venus and use the gravity of Venus to turn around and return.

It is not difficult for astronauts to achieve this. If it is not possible, they can also seek support from the ground. The relevant data will be calculated by the ground, and the astronauts will only be responsible for the implementation.

Afterwards, Anthropocene was in place, and also fired more than 200 specially-made missiles at the asteroid group.

Two groups of missiles fly towards the asteroid group in the universe, just like two groups of moths rushing to the bonfire, but the positions of these two groups of moths are under the monitoring of the earth at all times, and the ground monitors the missile groups every day. Fine-tuning the position of the missile to ensure that the missile group continues to fly towards the asteroid group.

Ordinary warheads cannot be adjusted after they are launched, and the universe is full of unpredictable interference factors. These two points are also important reasons for countries to abandon ordinary warheads and switch to missiles, even if they have to pay a huge cost for this.

On the eighth day after the missiles were launched, the first wave of missiles was about to encounter the oncoming asteroid swarm. At this time, the asteroid swarm was still maintaining a high speed of 16 kilometers per second, and the flying speed of the missile swarm was 11 kilometers per second. Kilometers, the relative speed is as high as 27 kilometers per second,

Even if Israel meets, the moment of meeting is only 0.037 seconds, too short to leave even a momentary image in human eyes.

Although the relative speed of the two sides is fast, it is not as fast as the detection speed of the radar. The special missiles in the missile group have been activated in advance under the control of the earth. The missile released a delayed detonation signal.

The asteroid swarm is coming at a gallop, and the first missile launched by the Earth is about to touch the asteroid swarm, but it receives a detonation signal before encountering the asteroid swarm. The nuclear warhead in the projectile detonates in advance four seconds before the encounter, and the dark universe Suddenly, a ball of blazing light exploded, and the energy of the explosion expanded in four hundred and eight directions instantly. The charged projectile produced a large amount of gas at high temperature, and with the support of the explosion energy, it turned into a circle of shock waves.

An asteroid passed by the light cluster at a very high speed. The original flight path was affected by the shock wave, and the asteroid's flight direction was deviated from what should not have occurred.

The duration of the nuclear bomb explosion was extremely short, but within a few seconds, it could already have an impact on dozens or even dozens of small lines.

Then, the second missile, the third missile... More than 200 missiles exploded at intervals of three to five minutes, continuously affecting the flight path of the asteroid.

The shock wave generated by a nuclear explosion is like a ball with ultra-low elasticity. Before the explosion dissipates, passing asteroids will be bounced by the shock wave to some extent. The number of unstoppable bounces is superimposed over and over again, and finally the asteroid's flight direction is moved.

The picture of the explosion was transmitted back to the ground through the space telescope. The heads of state and relevant personnel who witnessed all this did not cheer at all.

It will take time to verify whether this method is effective, and it is too early to celebrate now.

In the next few days, the missiles launched by the two spaceships detonated one after another, and the space telescope and asteroid radar finally determined that the flight orbits of the asteroid group had deviated. Sixty percent of the asteroid orbits had deviated from the earth. A little smile finally appeared on his face, but there are still 40% of the asteroids left!

At this time, it was finally the turn of the Victory to play.

During the more than 20 days when Earth and Humanity flew head-on to the asteroid group, Victory had already installed the electromagnetic thrusters that were built in a hurry, which happened to come in handy at this time.

Not only that, but satellites will be used as carriers in the future to send more missiles into space to form a near-ground defense network aimed at crushing asteroids. The intercontinental missiles of various countries have also entered a state of full combat readiness and are ready to be launched at any time , to meet an asteroid heading towards Earth. To be continued.
