Wang Tu was checking the launch plan for December 12, and after flipping through the arrangement documents, he used his own special genetic code seal to stamp the launch arrangement documents electronically.

On December 12, 13 and 14, the Kaohsiung base launched 12 batches to carry eight space station compartments, fuel, and engines into outer space, which will be used to expand the new Kaohsiung space station.

In addition, this is also for manned spaceflight, make preparations in advance, these 12 batches of spacecraft, two of which will carry electromagnetic field generators, these two electromagnetic field generators, are developed to imitate the magnetic field of the blue star, mainly to isolate cosmic rays.

The electromagnetic field generator with the hybrid gel coating can block most of the cosmic rays, and there are very high-level gamma rays or large-scale neutron irradiation, otherwise the living area of the space station is almost as safe as the ground of the blue star.

Suddenly, a sound of hurried footsteps came from outside Wang Tu's door, and his assistant hurriedly rushed in: "Huhu! Wang Ju, something is wrong. ”

"What's the matter?" Wang Tu put down the information he had just called up and asked.

"There's something wrong with that WX asteroid, and that's what our satellites have just monitored." The assistant hurriedly handed a document to Wang Tu.

Wang Tu suddenly became nervous, and hurriedly took the document and carefully browsed it.

In previous NASA reports, the WX asteroid is an Apollo-type rocky asteroid, meaning that it passes through the orbit of the Blue Star in an orbit similar to that of the Apollo asteroid in 1862.

They estimated the rock to be between 144 feet and 324 feet (44 to 99 meters) in diameter, with NASA estimating the upper limit at about 99 meters in diameter.

But the Space Development Commission re-detected the WX asteroid today (Dec. 7 at 9:24 a.m.).

According to further detection data, the asteroid has a maximum diameter of 273 meters, a minimum diameter of 122 meters, and an average diameter of about 184 meters, and the WX asteroid has an olive shape.

This situation is not the most important thing, the most important thing is that this WX asteroid is not a rock-type asteroid analyzed by NASA, but an iron-nickel type asteroid with a density of up to 7.9 tons per cubic meter (type M asteroid).

According to the volume of the WX asteroid, the mass of this asteroid weighs 4.2~450 million tons.

If the WX asteroid follows its previous orbit, it will pass by about 4.1 million kilometers from Blue Star, a distance almost 11 times the distance of the Moon, and after this flyby, the asteroid will approach Venus again in August 2021.

But......

Seeing the last page of the document, Wang Tucai gasped, because the asteroid was about 6.42 million kilometers away from Blue Star, and suddenly changed direction, and this direction was exactly coming towards Blue Star.

The WX asteroid is getting closer and closer to the blue star, and the incredible speed of the WX asteroid is about 15.59 kilometers per second or 34,873 miles per hour (56,124 kilometers per hour).

At such a speed, after 108~109 hours, the WX asteroid will make close contact with our blue star, even at a negative distance.

Archaeologists' research tells us that humans were not the first aborigines on the Blue Star, and that before the advent of humans, it was actually the dinosaurs that ruled the Blue Star.

Until about 65 million years ago, a meteorite with a width of about 9.7 kilometers struck the blue star at a speed of more than 40 times the speed of sound, and its impact caused the species on the blue star to be virtually extinct.

Therefore, the blue star has enough living space for the remaining creatures, and human beings have enough time and living space to develop and grow.

Although it has been a long time since meteorites caused the extinction of the dinosaurs, the lethality of meteorites has also been confronted in recent decades.

In 2013, a meteorite struck the Chelyabinsk region, destroying nearly 3,000 houses and injuring more than 1,200 people.

According to the data, the culprit of all this is only one cubic meter.

The reason why this meteorite was not burned up when passing through the atmosphere is that the meteorite is a very rare iron-nickel meteorite, which has the hardness to resist the heat generated by friction with the atmosphere, and the meteorite has a flight speed of 30~40 kilometers per second, so it has a chance to reach the surface of the blue star.

Although Blue Star has a conscientious satellite like the Moon and bears a large number of meteorite impacts for Blue Star, the number of meteorites that have hit the Earth in history has exceeded 10,000 meteorite samples collected by scientists at the South Pole alone.

A few years ago, scientists also detected a meteorite with a diameter of about 56 kilometers under the 848-meter ice sheet in Antarctica, which is much larger than the meteorite 65 million years ago.

This discovery means that the extinction of several creatures in the blue star before may be related to this, so human beings should be more aware of the threat of these asteroids to the life of the blue star.

So at the limits of human existence, how big a meteorite will be to destroy humanity?

According to scientists' calculations, there are countless dust and small near-Earth objects around the blue star, but not all of them can enter the Earth and become a meteorite.

Celestial bodies that can enter the Blue Star are impossible to ignore in terms of mass, volume, and velocity.

Generally, meteorites entering the blue star will burn in the atmosphere, because the friction of the air causes the meteorite to gain a lot of heat during the process of entering the atmosphere.

If a rock meteorite made of a mixture of gravel and ice slag enters the Blue Star at this time, it will be difficult for the meteorite to cause harm to humans living on the Blue Star, because it has already evaporated when it enters the Blue Star's atmosphere.

Of course, this situation only exists when the diameter of the meteorite is less than 100 meters, if this meteorite is replaced by an iron meteorite, even if it is protected by the atmosphere, the meteorite can still easily enter the blue star, and in serious cases, it can easily destroy a city.

If the diameter of the meteorite is more than 10 km, then at this time, the mass of the meteorite is no longer considered.

Because in this case, no matter how hard the Blue Star atmosphere tries, the fuel will eventually go to extinction, just like the previous Earth overlords.

Because the power of a meteorite of more than 10 kilometers is equivalent to 10 billion mushrooms with a yield of 300,000.

Wang Tu's face is hard to see the pole, an iron-nickel asteroid with an average diameter of 182 meters will collide directly with the blue star after 108~109 hours.

Iron-nickel asteroids are not only difficult to consume in the atmosphere, but what is more terrifying is that its high density leads to about 2~3 times the power of rock asteroids of the same volume.

This power is equivalent to those rocky asteroids with a diameter of 400~500 meters.

"Immediately convene an emergency meeting." Wang Tu made a decision immediately.

"Yes, I'll arrange it right away." The assistant hurriedly ran to arrange an emergency meeting.

In less than an hour, not only the Space Development Committee knew about it, but also NASA, the Western Space Agency, the Maoxiong Space Agency, the Tianzhu Space Agency and other space agencies knew about it.

In the face of such a major matter of human life and death, countries have to put aside their prejudices and exchange intelligence and information with each other to prepare for how to deal with this WX asteroid.

For a while, space agencies and governments around the world were lively, but in order to avoid causing panic among the people, they all coincidentally blocked the news now.
