While Chen Xin is actively working to save himself, governments of various countries will certainly not be idle.
The first to take action were of course the top five Blue Stars.
Although we often laugh at the fact that the top five Blue Star countries can only be counted as two and a half, and the remaining two have to be eliminated, in fact these five countries are still one of the five most powerful countries in the world, and other countries are not the same as these five. Compared with other countries, after all, they are lagging behind in terms of comprehensive national strength and response to such disasters.
Of course, in the face of this crisis for all mankind, countries around the world have put aside their prejudices and decided to work together.
Among the actions carried out by various countries, the first choice is of course to destroy meteorites or change their orbit.
After all, this is obviously simpler and less troublesome than surviving the doomsday, and it can also minimize the impact of meteorites on Blue Star.
But for today's Blue Star civilization, destroying a meteorite with a diameter of more than ten kilometers is actually more difficult than climbing to the sky.
There are really not many practical solutions that countries can come up with.
In the United Nations special meeting led by the top five Blue Stars, various plans were proposed and rejected. In the end, only three plans were approved by the majority of people and passed.
Plan No. 1 was proposed by Yan Guo. When the meteorite approaches the lunar orbit, a high-power thruster will be installed on its surface to change the orbit of the meteorite with the help of the moon's gravity, thereby preventing the meteorite from hitting the blue star.
This plan is the most feasible and effective among the three currently available, but it is also the most technically difficult.
With the aerospace technology currently possessed by mankind, it has only achieved manned spaceflight in the Earth-Moon system. In the space beyond the lunar orbit, humans have only launched probes, hoping to add propulsion to meteorites when they approach the lunar orbit. This project itself is a great test for human aerospace technology.
Not to mention adding thrusters to the meteorite and being able to push this behemoth with a diameter of more than ten kilometers.
Even with the help of the moon's gravity, this still requires transporting a propeller much more powerful than the largest spacecraft currently built by mankind, as well as the fuel needed to propel the meteorite.
Although humans were able to urgently modify a spacecraft capable of doing this in three months, the success rate of this plan is still not high.
Plan No. 2 was proposed by the federal people and was based on the sci-fi films "The End of the World" and "The Great Collision" that were filmed by Hollywood at that time. Thanks to the genius of the Hollywood screenwriters at that time, they were able to formulate this plan.
That is to land on the meteorite, then make a hole in the meteorite, bury the nuclear bomb, and then detonate it.
If all goes well, the power of the nuclear bomb explosion is enough to change the trajectory of the meteorite, or at worst, it can crush the meteorite, reduce its size, and reduce the harm caused by the impact.
The technical difficulty of this solution is lower than that proposed by Yan Guo. Although both solutions require landing on a meteorite, it is obviously much less difficult to install a nuclear bomb than adding a propeller, and it can propel the nuclear bomb of the meteorite. Far easier to build than a thruster capable of pushing meteorites.
Nuclear bombs of this level are already available in the nuclear arsenals of the top five Blue Stars. Lucia even said on the spot that they could provide Tsar bombs if this solution was adopted.
But a big problem with this plan is that although the nuclear bomb explosion can push the meteorite, it is more likely to directly crush the meteorite, causing multiple meteorites to hit the blue star.
In this case, the damage to the Blue Star civilization will not be lower than the meteorite hitting the Blue Star as a whole, so during the discussion, various countries are more inclined to the plan proposed by Yan Guo.
However, considering the difficulty of implementing Yanguo's plan, this plan was retained as a necessary PLANB.
As for the third plan, it was proposed by the Lucians.
The Lucian people's plan was very simple and direct. It was brutal and very characteristic of a fighting nation. It was to directly use all the existing nuclear weapons of the five Blue Stars to carry out a saturation nuclear strike on the meteorite and blow it into pieces.
Although the fragments will still impact the surface of the blue star after entering the atmosphere of the blue star, the damage caused by the shattered meteorites is at least what human civilization can withstand, and most of the fragments will burn when entering the atmosphere. After all, there won't be too many fragments falling on the blue star.
But this plan also has a problem, that is, mankind's existing nuclear bomb launching technology is not enough to allow the nuclear bomb to fly too far in space, so it must wait until the meteorite is close enough to the Blue Star before the nuclear bomb can be launched.
And in order to ensure the hit rate of the nuclear bomb, a spacecraft needs to be sent to guide the nuclear bomb.
But after the nuclear bomb shattered the meteorite, the spacecraft faced the overwhelming meteorite fragments. There was a high probability that it would not survive.
This is like laser guidance on the battlefield. If it is a cruise missile, the soldiers on the ground can still keep a safe distance from the target. But if it is a cloud burst bomb or simply a nuclear bomb, let alone It is this soldier, and all the soldiers on the entire battlefield will have a hard time surviving.
However, considering that this is a matter of life and death for mankind, countries do not feel that it is a difficult choice to make noble sacrifices for the survival of the entire human civilization.
In fact, although the implementation difficulty and success probability of the three plans are different, the astronauts performing the mission are all risking their lives, and they are all likely to die as a result.
After fierce arguments and discussions, countries finally decided to implement a saturated response plan, with three plans being carried out simultaneously.
The Yan Kingdom and the Federation will first land on the surface of the meteorite, install thrusters and nuclear bombs respectively, and then try to use nuclear bombs and thrusters to change the orbit of the meteorite or blow it up.
Lucia's plan serves as preparation for a final give-and-take. If the first two plans fail, then this will be mankind's last effort to deal with meteorites.
In addition, countries will also take active self-rescue measures, build underground bunkers, reserve supplies, and at the same time save as many people as possible and strive to keep more people alive.
In the face of a common disaster for all mankind, countries around the world have erupted in unprecedented unity this time. Even countries that are reluctant to deal with it are now working together.
The Federation took the initiative to provide the Falcon rocket to the Yan Kingdom. At this time, every effort can increase the chance of human survival. Technical blockade is not what should be done at this time.
The Lucians also opened up their nuclear arsenal, and donated several Tsar bombs that had been secretly preserved from the Sovian era. Two of them will be used in the federal plan to transport meteorites for blasting operations.
At the same time, the top five Blue Stars also gathered all the world's aerospace resources and invested in the implementation of the three plans.
However, in addition to active self-rescue plans, countries are also preparing backup plans for meteorites to hit Blue Star in case the plan fails. (End of chapter)
