Doomsday Bunker Upgrade

　　 While Chen Xin is actively working to save himself, the governments of all countries will certainly not be idle.

　　 The first one to take action was of course the top five Blue Stars.

Although we often ridicule that the top five Blue Stars are only two and a half, and the remaining two have been removed from the list, in fact these five countries are still one of the five most powerful countries in the world, and other countries and these five Compared with the country, after all, the overall national strength and response to such disasters are a little worse.

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

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

　　 After all, it is obviously simpler and less troublesome than Survival Doomsday, and it can also avoid the impact of meteorites on Blue Star to the greatest extent.

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

　　 There are really not many practical solutions that countries can come up with.

　　In the special meeting of the United Nations headed 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.

　　 One of the plans was proposed by Yan Guo. When the meteorite approaches the lunar orbit, a high-power propeller is installed on the surface of the meteorite. With the combined action of the lunar gravity, the meteorite's orbit is changed to prevent the meteorite from hitting the blue star.

　　 This scheme is the most feasible and effective among the three schemes, but the technical difficulty is the most difficult one.

With the current aerospace technology possessed by mankind, only manned spaceflight in the Earth-Moon system has been realized. Humans have only launched probes in the outer space of the moon orbit, and want to install propulsion for meteorites when they approach the moon's orbit. This project itself is a great test of human aerospace technology.

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

　　 Even with the help of lunar gravity, this still requires the transportation of a propeller that is much more powerful than the largest spacecraft currently built by mankind, and the fuel needed to propel the meteorite.

　　 Although humans can urgently modify a spacecraft that can do this in three months, the success rate of this plan is still not high.

The 　　 No. 2 plan was proposed by the federal people. With reference to the science fiction films "Peerless Tribulation" and "World Clash" filmed in Hollywood, they were able to formulate this plan thanks to the talent of Hollywood screenwriters.

　　 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 generated by the nuclear bomb explosion is enough to change the orbit of the meteorite, and at worst, it can crush the meteorite, reduce its size, and reduce the damage caused by the impact.

This solution is technically less difficult than the one proposed by Yanguo. Although both solutions need to land on meteorites, it is obviously much less difficult to install nuclear bombs than installing thrusters, and nuclear bombs that can push meteorites It is much easier to build than a propeller that can propel meteorites.

　　 There are ready-made nuclear bombs of this level in the top five Blue Star nuclear arsenals. Lucia even stated on the spot that they can provide Tsar bombs if this scheme is adopted.

　　 But a big problem with this plan is that although a nuclear bomb explosion can push a meteorite, it is more likely that it will 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 that of the meteorite hitting the Blue Star as a whole, so in the discussion process, countries are more inclined to the plan proposed by the Yan State.

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

　　 As for the third proposal, the Lucias proposed.

　　 The Lucia’s plan is very simple and straightforward. It is rude and has the characteristics of a fighting nation. It is to directly use all the existing nuclear weapons of the top five Blue Stars to carry out a saturated nuclear attack on the meteorite and blow it into pieces.

Although the fragments will still impact the blue star's surface after entering the atmosphere of the blue star, the damage that the meteorites that have been blown up can bring is at least human civilization can withstand, and most of the fragments will burn when they enter the atmosphere. Exhausted, there will not be too many fragments falling on the blue star.

　　 There is only one problem with this plan, that is, mankind’s existing nuclear bomb launch technology is not enough to allow nuclear bombs to fly too far in space, so it must wait until the meteorite is close enough to the blue star to launch a nuclear bomb.

　　 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 smashed the meteorite, the spacecraft faced the overwhelming meteorite fragments. There is a high probability that it will 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 bomb or a nuclear bomb, let alone It is this soldier, it is difficult for all soldiers on the entire battlefield to survive.

　　 However, considering that this is a matter of life and death for human beings, UU reading www.uukanshu.com countries do not think that making noble sacrifices for the survival of the entire human civilization is a difficult matter to choose.

　　 In fact, although the difficulty of implementation and the probability of success of the three programs are different, the astronauts performing the mission are risking their lives, and they are likely to sacrifice for it.

　　 After fierce quarrels and discussions, the countries finally decided to implement a saturated response plan, and the three plans were carried out simultaneously.

　　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 orbit of the meteorite or explode it.

　　 And Lucia's plan is to prepare for the last let go. If the first two plans fail, then this will be the last human effort to deal with meteorites.

　　 In addition, countries will also take active self-rescue measures, build underground bunkers, store supplies, and at the same time save as many people as possible and strive to let more people survive.

　　In the face of the common disaster of all mankind, all countries in the world have burst out of unprecedented unity this time. Even the countries that do not deal with it are working together at this time.

　　 The Federation took the initiative to provide Yan Nation with the Falcon rocket. At this time, every bit of effort can increase the chance of human survival by one point. Technical blockade is not something that should be done at this time.

　　 And the Lucias also opened up their nuclear arsenal. Several czar bombs secretly preserved in the Soverian era were all donated. Two of them will be used in the plan of the Federation to carry meteorites for blasting operations.

　　 At the same time, the top five Bluestar also gathered all the global aerospace resources and invested them in the implementation of the three plans.

　　 However, in addition to active self-rescue plans, countries are also preparing backup plans for meteorites to strike Blue Star in case the plan fails.
