While Chen Xin is actively trying to save himself, governments will certainly not be idle.

The first to take action is, of course, the Blue Star Five.

Although we often laugh at the Blue Star Five, which can only be counted as two and a half, and the remaining two have already been removed, the fact is that these five countries are still among the five most powerful countries in the world, and the other countries are ultimately inferior in terms of overall national strength and response to such disasters.

Of course, in the face of this crisis for all mankind, the countries of the world have put aside their preconceptions and decided to work together.

The first choice of the actions carried out by various countries is, of course, to destroy the meteorite, or to change its orbit.

After all, it is obviously easier and less troublesome than surviving in the apocalypse, and it can also minimize the impact of meteorites on the blue star.

But a meteorite with a diameter of more than ten kilometers, for today's Blue Star civilization, it is really more difficult to destroy it than to ascend to the sky.

There really aren't many practical solutions that countries can come up with.

At the special session of the United Nations, led by the Blue Star Five, various proposals were proposed and rejected, and in the end, only three sets of plans were approved by the majority of the people.

One of the first plans was proposed by Yan Guo, when the meteorite approached the lunar orbit, a high-power thruster was installed on its surface, and the meteorite orbit was changed with the joint action of the moon's gravity, so as to avoid the meteorite hitting the blue star.

This scheme is the most feasible and effective of the three schemes, but the most technically difficult.

With the current space technology possessed by mankind, it has only realized manned spaceflight within the Earth-Moon system, and human beings have only launched probes in the space beyond the lunar orbit, and they want to install thrusters on meteorites when they are close to the lunar orbit, and this project itself is a great test of human space technology.

Not to mention the need to add thrusters to the meteorite, but also to be able to propel this behemoth with a diameter of more than ten kilometers.

Even with the help of the moon's gravity, it would still require a thruster that is much more powerful than the largest spacecraft ever built, as well as the fuel needed to propel the meteorite.

Although in three months, mankind was able to urgently modify a spacecraft that could do this, but the success rate of this program is still not high.

The second plan was proposed by the Federation, referring to the science fiction films "Peerless Tribulation" and "Heaven and Earth Collision" filmed in Hollywood that year, and thanks to the genius brains of Hollywood screenwriters back then, they were able to formulate this plan.

That is to land on a meteorite, then make a hole in the meteorite, bury a nuclear bomb, and then detonate it.

If all goes well, the power of a nuclear bomb explosion would be enough to change the trajectory of the meteorite, or at worst, shatter the meteorite, reduce its size, and reduce the damage caused by the impact.

This plan is less technically difficult than the plan proposed by Yan Guo, although both plans require landing on meteorites, but compared to installing thrusters, it is obviously much less difficult to install nuclear bombs, and nuclear bombs that can push meteorites are far easier to build than thrusters that can push meteorites.

The nuclear arsenals of the Blue Star Five of this level of nuclear bombs are readily available, and Lucia even said on the spot that if this plan is adopted, they can provide the Tsar Bomba.

But there is a big problem with this plan, that is, although the explosion of a nuclear bomb can push the meteorite, it is more likely to directly smash the meteorite, causing a situation where multiple meteorites hit the blue star.

In this case, the damage to the Blue Star civilization will not be lower than the overall impact of the meteorite on the Blue Star, so the countries are more inclined to the plan proposed by the Yan State in the process of discussion.

However, considering the difficulty of implementing the Yanguo plan, this plan was retained as a necessary PLAN B.

As for the third option, it was proposed by the Lucians.

The Lucian plan was very simple and straightforward, and the brutality was very characteristic of a fighting nation, that is, to directly use all the existing nuclear weapons of the Blue Star Five to carry out a saturation nuclear strike on this meteorite and blow it to pieces.

Although the debris will still cause an impact on the surface of the blue star after entering the atmosphere of the blue star, the damage caused by the meteorite that has been blown up is at least what human civilization can bear, and most of the debris will burn up when it enters the atmosphere, and not too much debris will fall on the blue star.

However, there is also a problem with this plan, that is, the existing nuclear bomb launch technology of mankind is not enough to make the nuclear bomb fly too far in space, so it must wait until the meteorite is close enough to the blue star before it can launch the nuclear bomb.

And in order to ensure the hit rate of the nuclear bomb, it is necessary to send a spacecraft to guide the nuclear bomb.

But this spacecraft will not survive the overwhelming meteorite fragments after the nuclear bomb shatters the meteorite.

This is like laser guidance on the battlefield, if it is a cruise missile, then the soldiers on the ground can still keep a safe distance from the target, but if it is a cloudburst bomb or simply a nuclear bomb, then let alone this soldier, it is difficult for all the soldiers on the entire battlefield to survive.

However, considering that this is a matter of life and death for the survival of mankind, countries do not feel that it is a difficult choice to make noble sacrifices for the survival of human civilization as a whole.

In fact, although the difficulty and probability of success of the three programs are different, the astronauts who carry out the mission are all risking their lives, and they are all likely to be sacrificed because of this.

After intense squabbling and discussion, the decision was finally made to implement a saturation response plan, with all three options running at the same time.

The Yan Nation 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 meteorite's orbit or blow it up.

Lucia's plan is a last-ditch stand, and if the first two fail, it will be humanity's last resort against meteorites.

In addition, countries will also take active self-rescue measures, build underground bunkers, stock up on supplies, and save as many people as possible to try to survive.

In the face of the common catastrophe of all mankind, the countries of the world have broken out in unprecedented solidarity this time, and even the countries that do not deal with each other are working together at this time.

The Federation took the initiative to provide the Falcon rocket for the Yan Country, and at this time, every effort can increase the chances of human survival by one point, and the technical blockade is not what should be done at this time.

The Lucians also opened their nuclear arsenal, and several Tsar Bombards secretly surviving from the Sovian era were all contributed, two of which were to be used in the Federa's program to be transported to meteorites for blasting operations.

At the same time, the top five Blue Star 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 the blue star in case the plan fails.
