No. N.1207 celestial body, arrival on Earth, thirty minutes ago.

The scientific researchers of the space command center are all waiting for the battle, and on the huge electronic display screen, a black-gray celestial body is simulated in 3D, which is rushing towards the earth at a speed of 70 kilometers per second.

That's right, 70 kilometers per second.

The speed is 25,000 kilometers per hour, which is not the fastest, after all, the first speed in the universe starts at 7.9 kilometers per second.

The shape of this giant celestial body, somewhat similar to an irregular rugby ball, has a pitted surface, but even the moving image simulated in 3D looks a little metallic.

After all, there is iron and nickel in the ingredients, and the staff in the command center, although their faces are serious, the atmosphere at the scene is not tense, and even some old experts are communicating softly.

A year ago, when it was determined that the place of impact between heaven and earth was in China's western region, Huaxia made a great deal of preparatory work for this purpose in the following time, and prepared dozens of interception plans alone.

In fact, it is not difficult to intercept celestial bodies, especially since China is still a nuclear-armed country, and it is absolutely possible to blast celestial bodies into scum outside the atmosphere and directly vaporize them.

The real difficulty is to keep some of the meteorite fragments and let them land at the designated location after the interception is successful.

Otherwise......

Who is responsible?

The most important thing is that the meteorite fragments must be kept below 100 meters, otherwise, meteorites above 100 meters fall on land, which is likely to produce a Tunguska explosion.

Its power is enough to destroy a small city, and even the shock wave of the explosion, covering an area of two thousand square kilometers.

Therefore, the 300,000 square kilometers of Qiangtang uninhabited area is the best place for celestial fragments to fall, because the place is large enough.

No way, who made our motherland a big land?

At the same time, the heads of government of all countries in the world are also focused on the Jiuquan Satellite Launch Base in Gansu, after all, rockets or something cannot be hidden at all.

Of course!

As a result of the launch of a nuclear bomb and its detonation outside the atmosphere, all countries were notified in advance by China.

Therefore, satellites in low-earth orbit around the world, without exception, are all bypassed, also to avoid the effects of a nuclear explosion.

But what really interests the heads of state is, how will China launch its nuclear bomb?

You must know that China has always been the country that did not use nuclear weapons first, and has never used nuclear bombs except for the development of nuclear bombs.

Therefore, the way in which the nuclear bomb is launched is particularly interesting.

Will the rocket be launched directly from the Jiuquan Satellite Base in Gansu Province? Or will it use the ballistic missile silos hidden in its territory somewhere?

It's a pity......

None of these are these, many countries that eat melons, including the United States, just watch it honestly, and want to meddle and interfere?

Shaft, you dare!

To paraphrase an old Chinese saying.

At the beginning, China's global call was not a verbal warning, because at this time, all of China's rapid reaction forces were on first-level combat alert.

If you want to fish in troubled waters or something, weigh the consequences yourself.

Not much to say, when the N.1207 celestial body was less than 10,000 kilometers away from the earth, the No. 1 chief, who was sitting in the command center, spoke:

"Contact the ground forces. ”

In the next second, on the huge electronic display, in addition to the 3D simulated dynamic image of the celestial body, there was once again a black and white night vision picture, after all, it was night.

However, the area in the picture is a location on the Qinghai-Tibet Plateau, and a 'land-based long-range ballistic missile' launcher more than 20 meters long and with 40 wheels appeared at the same time.

Well, abbreviated as ...... East wind.

It is the second in the Dongfeng family, the 'Dongfeng-31A', which has a range of up to 13,000 kilometers, which is enough to bombard the grandmother's house in the United States.

And the person who controls this Dongfeng is the most mysterious unit in China.

Second artillery!

The scientific researchers in the command center, after seeing this Dongfeng with their own eyes, many young people were excited, if it was not for the wrong occasion, they had to shout loudly.

Oriental Express, the mission must be achieved!

It's a weapon of the nation, and now it's time to use it, but outside the picture, it's not just a Dongfeng.

A few kilometers away, there is also a Dongfeng-31A, which is waiting solemnly, also for the sake of insurance.

The use of nuclear bombs to bombard celestial bodies is also the first time for Huaxia, no, the whole world is the first time, and the danger that needs to be borne behind this cannot tolerate any failure.

With the order of the No. 1 leader, the modified Dongfeng erected a missile bay of more than 20 meters and gradually began to warm up.

The reason for the modification is very simple: although land-based ballistic missiles can also break through the atmosphere, they are still a little worse than hitting targets outside the sky.

Therefore, there is a slight modification, and the specific parameters are not detailed, after all, Aunt River Crab is staring at it.

In the process of warm-up, the No. 1 leader stared at the electronic screen and said in a deep voice:

"I believe that this extraterrestrial crisis will be a great gift from the universe. ”

In just a few minutes, Dongfeng Express finished preheating, and the second artillery operator in the car quickly entered a long string of electronic keys and plugged them in......

Anyway, with the use of nuclear weapons, only the No. 1 leader can give orders.

At the same time, the scientific researchers in the command center have long been connected to the ballistic missile, and there are many technicians at the same time, and then reported three times in a row:

"Everything is normal in the missile bay, it warms up well, and ignition is expected in two minutes. ”

"Celestial body No. N.1207, within 6,000 kilometers of the Earth. ”

......

Two minutes go by in a flash, and the best part comes!

Like a rocket launch, the coder holds the microphone and says:

"Countdown to ignition, 10... 9... 8... 7......”

When the countdown reaches zero, all that's left is two words.

Fire!!!

No, it's a fire, well, it's supposed to be a launch!

Call!~

The missile bay in the picture opens automatically, accompanied by a puff of white smoke, and the east wind, which has 40 wheels, violently shakes.

In the next second, a ballistic missile carrying a nuclear warhead, like a sword in the sky, with a huge flaming tail, quickly flew into the dark night sky.

Fire Fire Fire ......

The loud flame tail was immediately detected by countries all over the world, and then caused the shock of countless people, actually using the east wind?

That's too easy, right?

Although Dongfeng can also hit satellites, if you want to hit celestial bodies, I'm afraid it's safer to use rockets, in fact, this worry is completely blind.

"The ballistic missile, which lasts for 10 seconds, has broken through the troposphere. ”

The troposphere is 16 kilometers above the ground, and the stratosphere is 16~48 kilometers upward.

According to popular science, the earth's atmosphere is divided into five parts, namely the troposphere, stratosphere, mesosphere, warm layer, and fugitive layer.

The five layers add up, a total of about 480 kilometers, and after reaching the dissipation layer, because the density of the atmosphere is too low, it is basically in a state of weightlessness, which can be regarded as entering the universe.

"The ballistic missile, which lasts 15 seconds, has passed through the ozone layer and is about to break through the stratosphere. ”

The ozone layer is in the stratosphere, at an altitude of about 20-25 kilometers, and in 15 seconds before and after, the speed of the Dongfeng missile is getting faster and faster.

"After 30 seconds of continuous flight, the missile reaches the first cosmic velocity and enters the warm layer. ”

"A rise in temperature, highly ionizing radiation, everything is normal with the nuclear warhead. ”

“......”

In about two minutes, the ballistic missile passed through the Earth's 480-kilometer atmosphere and entered the universe, reaching an astonishing speed of 20 kilometers per second.

Only at this moment did the missile abandon the entire fuel tank, and the circular warhead quickly detached and accelerated towards the celestial body thousands of kilometers away.

In other words, the east wind will dry to the sky as soon as it starts!

After about five minutes......

Under the control of scientific researchers, when the circular warhead was 1,000 kilometers away from the celestial body, the warhead separated again and turned into eight nuclear bombs in the shape of triangular tips.

Or rather, eight hydrogen bombs with a yield of 1 million.

Nuclear bomb is a general term, including the atomic bomb and the hydrogen bomb, although the two principles are different, but the latter is more powerful, and the residual nuclear radiation after the explosion is also less.

In fact, there is no need to worry at all, after all, it is outside the atmosphere, this is the category of the universe, the earth is always in motion, and nuclear radiation cannot have the slightest effect.

The reason why hydrogen bombs are used is because of the high temperature and the strong controllability of nuclear fusion, especially this kind of precision strike.

However, I saw that the eight sharp-angled hydrogen bombs in the electronic screen formed a special formation, and in an instant, they collided with the celestial bodies rushing towards the earth and penetrated deeply.

Explode......

It didn't happen, because the scientists in the command center were all waiting, and it was not time to detonate it now.

It is necessary to wait until the celestial body is close to the earth, and then detonate the hydrogen bomb, otherwise the meteorite fragments, don't think about it, I am afraid that if it does not fly to the universe, it will also fall in other parts of the earth.

The former is fine, the latter is to make a wedding dress for others, and if the fragments fall on the human gathering place, the consequences will be unimaginable.

N.1207 celestial body, 3000 km from Earth......

N.1207 celestial body, 2000 km from Earth......

N.1207 celestial body, 1000 km from Earth......

......

When the object was captured by the earth's gravity, the distance was shortened to less than 1,000 kilometers, and the command personnel in the command center immediately issued an order:

"Boom!"

On the surface of the black-gray celestial body, eight sun-like lights immediately appeared, instantly illuminating the night side of the earth as if it were day.

The nuclear explosion happened, but it was so quiet that there was no sound.

After all, in the universe, in a vacuum, sound cannot be transmitted, so the electronic screen has become white.

At the same time, everyone in the command center collectively held their breath and waited until the light disappeared, and the electronic screen turned into countless meteorite fragments.

Through precise scanning, this celestial body of about 10 million tons was vaporized by a hydrogen bomb by 20 percent on the spot, and the remaining 80 percent formed more than 5,000 meteorite fragments......

The technician said excitedly, although there are more than 5,000 meteorites, but after the friction and filtration of the atmosphere, most of the meteorites will be consumed, and there is no slag left.

After all, there is still solid water in many meteorites, and when meteorites pass through the earth's atmosphere, there will be five times of slimming, so more than 5,000 meteorites can fall on the earth three-fifths, which is already good.

But even so, these more than 3,000 celestial meteorites, which add up to at least a few million tons, can definitely be regarded as treasures.

"After calculation, the meteorite fragments will fall on the target site, the Qiangtang no man's land. ”

The nearly 300,000 square kilometers of Qiangtang uninhabited area is definitely the best place for meteorites to fall, and the scientific researchers in the command center collectively cheered.

Dongfeng Express, live up to expectations!

The No. 1 leader also rarely smiled, but what really made people happy was that the 'Tianhe' supercomputer immediately made calculations about the results after the nuclear explosion.

The meteorite showers that have turned into meteor showers and are passing through the Earth's atmosphere are initially estimated to be the largest fragments in diameter after falling into the uninhabited area of Qiangtang, which should not exceed 60 meters in diameter.

In other words, the near-Earth objects that attacked the earth were not only defeated by Huaxia, but the largest meteorite fragments were also successfully controlled below 100 meters, avoiding the occurrence of the Tunguska explosion.

This is another victory for China's aerospace industry!

However......

Even so, Chen Ya, who is alone in the uninhabited area of Qiangtang, may not be able to save his life.

......
