Wang Tu was checking the launch plan for December 12. After flipping through the arrangement documents, he used his own special genetic code seal to electronically stamp the launch arrangement documents.
On December 12, 13, and 14, the Kaohsiung base launched 12 batches, carrying eight space station cabins and fuel and engines to outer space. These things will be used to expand the new Kaohsiung space station.
In addition, this is also to prepare for manned spaceflight in advance. Two of these 12 batches of spacecraft will carry electromagnetic field generators. These two electromagnetic field generators are developed to imitate the magnetic field of Blue Star.
Mainly to isolate cosmic rays.
The electromagnetic field generator combined with the hybrid gel coating can block most cosmic rays, especially high-energy gamma rays or large-scale neutron irradiation. Otherwise, the safety level of the living area of the space station is almost the same as that of the Blue Star ground.
.
Suddenly, a rush of footsteps came from outside Wang Tu's door, and his assistant rushed in hurriedly: "Hoo hoo! Director Wang, something serious is going to happen."
"What's the matter?" Wang Tu asked, putting down the information he had just retrieved.
"There is something wrong with asteroid x. This is what our satellite just monitored." The assistant quickly handed a document to Wang Tu.
Wang Tu suddenly became nervous and quickly took the document and browsed it carefully.
According to previous reports from NASA, Asteroid X is an Apollo-type rocky asteroid, which means that it crosses the orbit of the Blue Star in an orbit similar to the 1862 Apollo asteroid.
They estimated the diameter of the rock to be between 144 feet and 324 feet (44 meters and 99 meters), with the upper limit of NASA's estimate being about 99 meters in diameter.
However, the Space Commission re-detected the asteroid x today (9:24 a.m. on December 7).
According to further 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 asteroid X shows an olive shape.
This situation is not the most important thing. The most important thing is that this asteroid
.
Calculated based on the volume of asteroid x, the mass of this asteroid weighs 420 to 450 million tons.
If this asteroid x follows its previous trajectory, it will pass by Blue Star at a distance of about 4.1 million kilometers. This distance is almost 11 times the distance of the moon. After this flyby, the asteroid will pass by in August 2o21
Close to Venus again.
but……
When he saw the last page of the document, Wang Tu took a breath, because the asteroid suddenly changed its direction at a distance of about 6.42 million kilometers from the Blue Star, and this direction happened to be heading towards the Blue Star.
At present, Asteroid X is getting closer and closer to the Blue Star, and the incredible speed of Asteroid
At this temperature, after 1o8 to 1o9 hours, Asteroid X will have a close contact with our blue star, even at a negative distance.
Research by archaeologists tells us that humans are not the first indigenous people on Blue Star. Before humans appeared, dinosaurs actually ruled Blue Star.
Until about 6.5 million years ago, a meteorite with a width of about 9.7 kilometers hit the Blue Star at a speed of more than 40 times the sound. The impact caused by it caused the basic extinction of species on the Blue Star.
Therefore, Blue Star has enough living space for the remaining creatures, and humans have enough time and living space to develop and grow.
Although it has been a long time since the meteorite caused the extinction of the dinosaurs, we have also faced the damage caused by meteorites in recent decades.
In 2013, Chelyabinsk Oblast was unfortunately attacked by a meteorite. Nearly 3,000 houses in the area were destroyed, and about 1,200 people were injured.
According to data, the volume of the culprit causing all this is only one cubic meter.
The reason why this meteorite was not burned up when passing through the atmosphere is because it is a very rare iron-nickel meteorite with a hardness that can withstand the heat generated by friction with the atmosphere, and the meteorite's flight speed has also reached 3o~4o.
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, which 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 in Antarctica 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 was far larger than the meteorite 6.5 million years ago.
This phenomenon means that the previous extinctions of life on Blue Star may be related to this, so humans must be more aware of the threat these asteroids pose to life on Blue Star.
So on the limit of human survival, how big a meteorite will cause humankind to perish?
According to scientists' calculations, 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 bodies that can enter the blue star cannot be ignored in terms of mass, volume and speed.
Generally, meteorites entering a blue star will burn in the atmosphere. This is because air friction will cause the meteorites to gain a large amount of heat during the process of entering the atmosphere.
If a rock meteorite composed of 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 entered the Blue Star's atmosphere.
Was steamed away.
Of course, this situation only exists when the diameter of the meteorite is within 1oo meters. If the meteorite is replaced by an iron meteorite, even with the protection of the atmosphere, the meteorite will eventually be able to easily enter the Blue Star, and in severe cases, it can easily destroy a city.
If the diameter of the meteorite exceeds 10 kilometers, then at this time, there is no need to consider the mass of the meteorite.
Because in this case, no matter how hard the Blue Star's atmosphere works, the fuel will eventually die like the previous earth overlords.
Because the power of a meteorite traveling 10 kilometers is equivalent to 100 million mushrooms with an equivalent weight of 300,000.
Wang Tu's expression was extremely sad. An iron-nickel asteroid with an average diameter of 182 meters will directly collide with the Blue Star in 1o8 to 1o9 hours.
Iron-nickel asteroids are not only difficult to destroy due to their atmosphere, but what is even more frightening is that their high density makes them about 2 to 3 times more powerful than rocky asteroids of the same size.
This power is already equivalent to those rocky asteroids with a diameter of 4oo to 5oo meters.
"Convene an emergency meeting immediately." Wang Tu made a decision immediately.
"Yes, I'll arrange it right away." The assistant hurriedly ran to arrange the emergency meeting.
In less than an hour, not only the Space Development Committee knew about this, but also NASA, Western Space Administration, Mao Xiong Space Agency, Tianzhu Space Administration and other space agencies.
Faced with this major matter of human life and death, countries have to put aside their prejudices, exchange intelligence and information with each other, and prepare how to deal with this x asteroid.
For a time, space agencies and governments around the world became excited, but in order to avoid causing public panic, they all blocked the news.
