On February 15, 2013, in Chelyabinsk, a bright light streaked across the sky, leaving a white trail, followed by a loud bang, a huge meteorite with a mass of 7,000 to 10,000 tons exploded 30 to 50 kilometers above the ground, disintegrating and forming a meteorite rain that fell to the ground, injuring more than 1,000 people.

Chelyabinsk was hit by such a huge meteorite, and the residents of Chelyabinsk were not warned by the government or government in advance.

Little Apophis moves around space appear to be irregular, which makes space agencies even more troublesome.

Because, the meteorite moves in space without regularity, which means that it is impossible to calculate, analyze and predict its flight trajectory and landing site, even if in Hollywood movies, the complex meteorite flight trajectory is successfully calculated, and the protagonist of the earth escaping the meteorite catastrophe can not be calculated, the meteorite movement is irregular, how to calculate!!

Now, however, countries around the world are staring at the United States on the map, the East Coast, the New York Inland Sea, 37 degrees northeast, 12 kilometers from the coast of New York.

This is where the 'Little Apophis' landed on the prophecy tablet.

However, the countries have not relaxed their vigilance, the anti-aircraft missiles are already on full display, the nuclear submarines cruising in the oceans, and the nuclear bomb silos hidden in various places by the nuclear powers are ready for launch, and the countries are preparing for the worst.

However, nuclear bombs will not be launched unless absolutely necessary. Once. A nuclear bomb is launched. The meteorite rain formed by the blowing up of the 'little Apophis', as well as the nuclear radiation energy, would be another disaster.

At 10 a.m. on July 3, 18 hours and 17 minutes before Little Apophis hit the Earth.

New York, as well as Massachusetts, Connecticut, New Jersey, and Delaware, most of the people living along the coast were evacuated.

New York, the capital of the world, has become an empty city. The streets of Times Square, SOHO and Fifth Avenue have lost their former prosperity and become very depressed, the Empire State Building, known as the Seventh Wonder of the World, has been emptied, and Wall Street, the center of world finance, has faded the color of money at this moment, turning into a yellowed photo, usually unusually busy on the road. Not a single car can be seen anymore, the water on the Hudson River in Manhattan is very calm, and the busy waterway restores the tranquility of the sunset.

At this moment, the capital of the world was choked by the throat and had stopped breathing.

At the junction of 3rd Street and E Street in the southwest of Washington, D.C., stands a modest 9-story office building.

This is the famous NASA headquarters, the 'brain' of the largest civilian space agency on the earth is active in this building, and the NASA headquarters with no 'personality' is not as easy to identify by its appearance as the White House and the Pentagon, but the astronaut model in a white spacesuit in the foyer on the first floor, and the toy-like space shuttle hanging from it, will not make you think that you have gone to the wrong door.

Although NASA's headquarters is not as well-known as some of its subordinate space centers, its headquarters in Washington, D.C., is the uncompromising hub of NASA.

NASA has about 30,000 regular employees, which is very large, but compared with other U.S. government agencies, NASA can be regarded as a lean army, not to mention the Department of Defense, which has a total of millions of people, and the newly established Department of Homeland Security after the 9/11 incident, also has 170,000 staff.

NASA has a Planetary Defense Coordination Office (PDCO), a new unit established in January 2016 to monitor and track asteroids, comets, and other celestial bodies in Earth's orbit for any potential celestial threat.

The 'Little Apophis' meteorite was observed by PDCO.

PDCO has been tracking the trajectory of the 'Little Apophis' meteorite, as well as calculating its landing.

In one of the offices of the PDCO, it was crowded with people, and there were several Cleveland presidents, vice presidents, defense secretaries, four-star generals.

Everyone stared at the big screen in front of them, which showed the flight trajectory of the 'Little Apophis' meteorite.

PDCO's Director, Dave Brown. "The Little Apophis meteorite is rocky, about 35 to 40 meters in diameter, and has a meteorite mass of 7 to 80,000 tons, which is 8 to 10 times the mass of the meteorite that landed in Chelyabinsk in 2013," Burek told President Cleveland. The 'Little Apophis' meteorite flies extremely fast in space, heading towards the Earth, and is expected to enter the atmosphere at a speed of no less than 64,000 kilometers per hour, which is equivalent to 17 times the speed of a bullet. ”

Dave. When Burek said this, his voice paused, and he said with some fear, "We can now sit here calmly and deal with the impact of 'Little Apophis' on the earth, which must be thanks to Chen Rui's warning a year ago, so that we can observe the 'Little Apophis' dozens of hours in advance, which allows us to have enough preparation and time to deal with the 'Little Apophis', if we let the 'Little Apophis' enter the earth's atmosphere to observe, with a meteorite in the atmosphere exceeding 64,000 kilometers / hour, then it will be too late." The fate of New York, predicted on the prophecy tablet, and the number of casualties of 2.17 million people was almost foreordained. ”

Hearing this, Cleveland nodded and said, "Indeed, all Americans need to thank Chen Rui, he saved the fate of New York, saved the lives of 2.17 million Americans, and saved the American economy. After speaking, he paused, and continued, "What about the landing place of the meteorite, and the extent of the damage caused to the earth. ”

Dave. Burek shrugged his shoulders and said, "I'm sorry. President. Because. 'Little Apophis' moves irregularly in space, so the extent of the damage to the Earth caused by the landing of the meteorite cannot be calculated.

You know, Mr. President, meteorites hit the Earth at different angles and caused different degrees of damage, and the meteorites hit the Earth at right angles. The kinetic energy generated is the largest, the degree of damage to the earth is the greatest, the meteorite hits the earth at a very small oblique angle, the degree of damage to the earth is the least, and the degree of damage caused to the earth by meteorites landing on the sea and hitting the land is very different.

However, one thing is certain, a meteorite with a diameter of 35 to 40 meters and a mass of 7 to 80,000 tons hit the Earth. The level of damage caused to the earth is level 3, PHO level. Potentially threatening celestial bodies, regional destructive effects, that is, if 'Little Apophis' descends on the New York Inland Sea, the destruction of nearby areas is devastating, and the tsunami caused by the first tsunami is New York, followed by Massachusetts, Connecticut, New Jersey, Delaware coastal coasts. ”

"Do you have any plans for what to do?" Cleveland continues to speak to Dave. Burek asked.

"Yes." Dave. Burek nodded and said, "We have formulated a detailed interception plan, first, launch a guide to deflect the flight path of the 'Little Apophis' meteorite, so that it will land in the direction of the middle of the Atlantic, and then, launch a nuclear bomb to destroy it, the meteorite rain formed after the meteorite destruction will land on the bottom of the Atlantic Ocean, and the nuclear radiation of the nuclear bomb explosion will remain on the Atlantic Ocean, so as to minimize the destructive power of the meteorite and the nuclear radiation impact of the nuclear bomb." ”

"How much success rate is there?" Cleveland looked at Dave. Burek asked.

"90%, the implementation of this plan, with a success rate of more than 90%, we also want to thank Chen Rui, he gave the specific landing location of the 'Little Apophis' meteorite, the New York Inland Sea, 37 degrees northeast direction, about 12 kilometers away from the coast of New York, we can determine the flight trajectory of the meteorite in the earth's atmosphere through reverse calculation, and then, launch a missile to deflect it, launch a nuclear bomb in the middle of the Atlantic Ocean to destroy it, otherwise, this interception plan has no success rate of 30%." ――

July 3, 22:40 ET.

The 'Little Apophis' meteorite flew out of the shadow side of the moon and brushed against the surface of the moon.

At this time, just by looking through the astronomical telescope, you can see the 'Little Apophis' meteorite, flying extremely fast and flying in the direction of the Earth.

July 4, 0:27 EST.

'Little Apophis' flew away from the moon's gravitational circle and headed in the direction of the Earth.

July 4, 2:17 a.m. ET.

The satellite observed that the 'Little Apophis' meteorite is only 27,680 kilometers above the ground, which means that the uninvited guest is in a low-Earth orbit, which is the orbit of a large number of man-made objects, including the International Space Station and Earth observation satellites, and the geosynchronous orbit, which is the orbit of the satellite that provides us with meteorological and communication services, and the latter is very close to the Earth.

The nations of the world are ready to spend a sleepless night.

Satellites around the world, space telescopes, keep a close eye on the 'Little Apophis' meteorite.

In the United States, anti-aircraft missile systems have already locked in the bearing.

Several nuclear submarines cruised in the middle of the Atlantic, designated positions.

Wait for the launch command.

The countries of the world have not relaxed either, the missile defense system has been raised to the highest alert level, and the nuclear warheads of the nuclear countries have been aimed at the sky, waiting for activation, command launch,.

In the command hall of NASA.

For President Cleveland, Vice President, Secretary of Defense, many generals, tonight is also a sleepless night.

On the large screen, the flight trajectory of the 'Little Apophis' meteorite, which was captured by the detection satellite, was shown.

It can be seen that the 'Little Apophis' meteorite is flying towards the Earth at an extremely fast speed

July 4, 02:47 a.m. ET.

The 'Little Apophis' meteorite entered the Earth's atmosphere because the meteorite burned with the atmosphere, dragging a long white flame tail behind the 'Little Apophis'.

"The little Apophis meteorite is now flying at a speed of 67,272 km/h, at an angle of 76.4 degrees, and is expected to hit the Earth in about 1 hour and 20 minutes."

"The 'Little Apophis' meteorite is now flying at a speed of 68,124 km / h, at an angle of 77.6 degrees, and is expected to land in the Atlantic Ocean in about one hour, and the specific azimuth cannot be calculated."

The 'Little Apophis' meteorite is now flying at a speed of 64,178 km/h, at an angle of 75.6 degrees, and is expected to land in the Atlantic Ocean in about 45 minutes. ”

Dave. Berlake walked up to President Cleveland lightly and said to the president, "Mr. President, 'Little Apophis' has 6 minutes and 42 seconds left to enter the first missile ambush point, whether to launch a missile interception or not." ”

"At this time, launch a missile to intercept, what is the success rate." Cleveland looked at Dave. Burek asked.

"Because the 'Little Apophis' meteorite is too high from the ground, the meteorite's flight speed and flight angle are constantly changing, so the success rate of launching missiles to intercept is only about 50%."

"Wait a little longer." Cleveland said.

The 'Little Apophis' meteorite is now flying at a speed of 65,171 km/h at an angle of 72.6 degrees, and is expected to land in the western Atlantic Ocean in about 32 minutes,"

"The 'Little Apophis' meteorite is now flying at a speed of 62,118 km/h, the flight angle is 71.6 degrees, and it is expected to land in the Atlantic Ocean in about 24 minutes.

Dave. Burek said to President Cleveland again, "Mr. President, 'Little Apophis' has 3 minutes and 12 seconds left to enter the second missile ambush site, whether to launch a missile to intercept it." ”

"What is the interception success rate?" Cleveland said.

“76%。”

"What are the consequences if this interception fails." President Cleveland expressed his vs to Dave. Burek asked.

"There are two consequences of interception failure, first, the missile did not hit the meteorite, which is the most ideal failure, no, it will affect the interception of the third missile ambush point, and second, the missile hit the meteorite, but the shot missed, then, the consequences are very serious, the third missile ambush point behind, the fourth missile ambush point all failed, and the meteorite fell to the last known landing site, perhaps, the meteorite landed on the Atlantic Ocean, or maybe it landed on the African continent, or Europe, Asia, which will cause a very serious international impact."

Also, it's okay to hit the 'Little Apophis' meteorite into the Atlantic, if you hit the meteorite on the land of another country, people will definitely stop doing it, and if it hits the land of a polar bear, people dare to throw a nuclear bomb at you directly.
