Chapter 360 Sudden Arrival
Wang Tu was checking the launch plan on December 12. After flipping through the arrangement documents, he used his special genetic code seal to stamp the launch arrangement documents with an electronic seal.

On December 12, 12, and 13, the Kaohsiung Base launched 14 batches, carrying eight space station cabins, fuel, and engines into outer space. These things will be used to expand the new Kaohsiung Space Station.

In addition, this is also for manned spaceflight, and the preparation work is made in advance. Among the 12 batches of spacecraft, two batches will carry electromagnetic field generators. These two electromagnetic field generators are developed by imitating the blue star magnetic field. Mainly to isolate cosmic rays.

The electromagnetic field generator combined with the hybrid gel coating can block most of the cosmic rays. Unless there are high-energy gamma rays or large-scale neutron irradiation, the safety of the living area of ​​the space station is almost the same as that of the Blue Star ground. .

Suddenly, there was a sound of hurried footsteps from outside Wang Tu's door, and his assistant rushed in: "Hoo hoo! Director Wang, something is wrong."

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

"There is something wrong with that WX asteroid. This is what our satellite monitored just now." The assistant quickly handed a document to Wang Tu.

Wang Tu suddenly became nervous, and quickly took over the documents and began to browse them carefully.

In previous NASA reports, this WX asteroid is an Apollo-type rocky asteroid, which means that it crosses the blue star in an orbit similar to the 1862 Apollo asteroid.

他们估计这块岩石的直径在144英尺到324英尺(44米到99米)之间，据NASA估值的上限就是直径99米左右。

But the Cosmos Development Council re-detected the condition of the WX asteroid today (December 12 at 7:9 am).

According to the further display of the detection data, the maximum diameter of this asteroid reaches 273 meters, the minimum diameter reaches 122 meters, and the average diameter is about 184 meters. This WX asteroid presents an olive shape.

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

Calculated according to the volume of the WX asteroid, the mass of this asteroid weighs 4.2 to 4.5 million tons.

If the WX asteroid proceeds according to its previous orbit, it will pass by about 410 million kilometers from the blue star, which is almost 11 times the distance from the moon. After this flyby, the asteroid will pass by in August 2021. Closer to Venus again.

but……

Wang Tu gasped when he saw the last page of the document, because the asteroid suddenly changed its direction at a distance of about 642 million kilometers from the blue star, and this direction happened to be heading towards the blue star.

At present, 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 34873 miles per hour (56124 kilometers per hour).

At this speed, after 108-109 hours, the WX asteroid will come into close contact with our blue star, even at a negative distance.

The research of archaeologists tells us that human beings are not the first aborigines on the blue star. Before the appearance of human beings, dinosaurs actually ruled the blue star.

Until about 6500 million years ago, a meteorite with a width of about 9.7 kilometers hit the blue star at a speed exceeding 40 times the speed of sound, and the impact caused the species on the blue star to be basically extinct.

It is also because of this that 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 dinosaurs, the lethality of meteorites has also faced the damage caused by meteorites to us in recent decades.

In 2013, the Chelyabinsk region of Maoxiong was unfortunately attacked by a meteorite. Nearly more than 3000 houses in the area were destroyed and more than 1200 people were injured.

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

The reason why this meteorite was not burned when it passed through the atmosphere is because the meteorite is a very rare iron-nickel meteorite, which has the hardness that can resist the heat generated by friction with the atmosphere, and the flying speed of the meteorite has also reached 30-40 Kilometers per second, so it has a chance to reach the surface of the blue star.

Although Bluestar has a responsible satellite like the moon, which bears a large number of meteorite impacts for Bluestar, the number of meteorites that hit the earth in history has exceeded 1 meteorite samples collected by scientists in Antarctica alone.

In the early years, scientists also detected a meteorite with a diameter of about 848 kilometers under the 56-meter ice sheet in Antarctica, which is much larger than the meteorite 6500 million years ago.

This discovery means that several extinctions of life on the Blue Star may be related to this, so humans must be more aware of the threat of these asteroids to life on the Blue Star.

So on the limit of human existence, how big a meteorite will make human beings die?
According to the calculation results of scientists, there are countless dust and small near-Earth objects around the blue star, but not all celestial bodies can enter the earth and become a meteorite.

The celestial body that can enter the blue star cannot be ignored in terms of mass, volume and speed.

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

If a rocky meteorite mixed with gravel and ice slag enters the blue star at this time, it will be difficult for this meteorite to cause harm to humans living on the blue star, because it has already been destroyed when it entered the blue star's atmosphere. was evaporated.

Of course, this situation only exists when the diameter of the meteorite is within 100 meters. If the meteorite is replaced by an iron meteorite, even with the protection of the atmosphere, the meteorite can easily enter the blue star in the end, and it can easily destroy a city if it is serious.

If the diameter of the meteorite exceeds 10 kilometers, then at this time, there is no need to consider the quality of the meteorite.

Because in this case, no matter how hard the blue star atmosphere works, human beings will eventually perish like the previous earth overlords.

Because the power of a meteorite over 10 kilometers is equivalent to 100 billion mushrooms with an equivalent of 30.

At the pole, an iron-nickel asteroid with an average diameter of 182 meters will directly collide with the blue star in 108-109 hours.

The iron-nickel asteroid is not only difficult to wear out the atmosphere, but what is even more frightening is that its high density makes it about 2 to 3 times more powerful than a rocky asteroid of the same volume.

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

"Call an emergency meeting immediately." Wang Tu made a prompt decision.

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

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

Faced with such a major event of human life and death, countries have to let go of their prejudices, exchange intelligence and information with each other, and prepare how to deal with this WX asteroid.

For a while, space agencies and governments all over the world became lively, but in order to avoid causing panic among the people, they all blocked the news now by coincidence.
