Three Hundred and Ninety Eighth Work Overtime

Other methods were suggested by the participants one after another, including spraying paint on asteroids, installing solar sails, illuminating mirror arrays, and even sending people to install nuclear bombs on asteroids.

However, these plans are not as they seem. It is not difficult to apply a layer of paint on the surface of the asteroid. You can directly launch the barrels containing the paint as shells and hit the asteroid to achieve the effect of painting. , the problem is that the thrust produced by this method is pitifully small, and it will take several years to change the orbit of the asteroid.

The same is true for mirror irradiation. Without enough time, the orbit of the asteroid cannot be changed at all.

The solar sail can be effective in a short period of time, even if the thrust generated by the solar sail is very strong, but the impact of the cosmic celestial body is really far away. As long as a little external force is applied to the asteroid, its orbit will be greatly changed. enough to push the asteroid out of its impact orbit.

However, the flying speed of this group of asteroids is as high as 200 kilometers per second, and it is gradually accelerating. It is impossible for any aircraft built by humans to catch up with the fast-moving asteroids.

Sending people to asteroids to install nuclear bombs is simply an impossible task.

It is not impossible to launch a solar sail head-on, but at a relative speed of more than 200 kilometers per second, no matter how high the mechanical strength of a man-made object, the result of hitting an asteroid is similar to that of an asteroid hitting the earth, and it will explode on the spot like a cannonball.

At this point in the discussion, the venue suddenly fell into a strange silence. One of the participating experts woke up like a dream: "Can the explosion push away the asteroid?"

"It should be possible." Another expert took out his mobile phone and quickly calculated, "If a ten-gram object hits the side of the asteroid at five times the speed of sound...assuming the mass of the asteroid is 100,000 tons...under ideal conditions, it can produce about every The displacement of 0.008 meters per second... then the displacement in one day is 700 meters, and the displacement in one month is 21 kilometers!"

"21 kilometers is too little, and it will not be enough to expand it by a hundred times."

"Then increase the number of hits!"

"Ladies and gentlemen, we only need to consider the feasibility, and leave it to the politicians to decide how to do it."

"Then what are we waiting for?"

The heated meeting came to an abrupt end, and the results of the meeting were quickly notified to all countries. The five major countries immediately conducted feasibility discussions, and then communicated with each other to finally determine the interception plan.

In order to complete the plan, the United States and Russia each contributed an electromagnetic gun that has not yet been installed. The shell is a 12.7mm warhead—note that it is a warhead, not a bullet. Anyway, there is no air resistance in the universe. As long as it can be launched from an electromagnetic orbit, no matter The shape of the bullet does not affect the trajectory.

In addition to the warheads obtained from the military factory, a large number of bearing steel balls of about ten grams were also obtained as ammunition.

Electromagnetic guns need enough electric energy to drive. If traditional solar panels are used to provide electric energy, the required area is too large. Just transporting the panels to space will take up a considerable part of the transportation capacity. This is an unbearable result anyway. .

To this end, China has contributed two small liquid metal reactors.

This kind of military reactor has been kept secret. The intelligence agencies of the United States and Russia only learned from the side that China may have such a reactor, but they have not obtained conclusive evidence.

If it weren't for the fact that he couldn't find a more suitable reactor, the first brother would definitely not want to bleed.

In fact, the micro-reactor is the most suitable reactor for aerospace engineering, but the output power of the micro-reactor is too low to carry the electromagnetic gun at all. The number of multi-reactor linkages is too large, and the time is too late to make it, so we can only Take the second step and get two liquid metal piles on top.

The electromagnetic gun must be installed on a stable weapon platform, but currently there are only two most stable space platforms, one is the International Space Station and the other is Tiangong.

The astronauts stationed at the space station immediately acted to prepare for the installation. Top experts from various countries designed the connection device between the rail gun and the space station as quickly as possible.

However, the space station is not a space battleship. After calculation, it is found that,

The vibration and recoil generated by the continuous firing of the electromagnetic gun will not only affect the normal attitude of the space station, but may also affect the overall structure of the space station, thus threatening the safety of the space station!

The final conclusion is that the railgun cannot be installed on the space station anyway!

For this reason, the five major powers launched emergency consultations again, but at the meeting, only China, the United States and Russia spoke, and Britain and France, which were yesterday's old flowers, kept their mouths shut very tactfully.

The result of the discussion is that a weapon platform must be customized for the electromagnetic gun. Countries and regions with spaceflight capabilities in the world use disposable spacecraft, which cannot be used as a weapon platform at all. Only Yankees have a unique space shuttle.

The Americans had to pull the long-retired space shuttle out of the museum, and summoned technicians to carry out comprehensive maintenance as quickly as possible. They did not ask for how many times the space shuttle could be used, but only for a successful one-time launch, even if it was thrown directly into the space after the mission was over. It doesn't matter in the universe.

Due to concerns that the space shuttle might crash during the launch, the United States pulled out four retired space shuttles in one go, but according to the launch plan, these retired space shuttles will not carry important materials such as electromagnetic guns or reactors during launch, so as to avoid accidents during launch. Accident.

That is to say, the combination of the space shuttle, the reactor and the electromagnetic gun must be carried out in space.

Although technicians from all over the world try their best to seal them up as a whole and minimize the difficulty of combination, the combination of the three is still not a problem that can be solved by connecting a wire, and must be guided by professionals on site.

To this end, various countries have urgently summoned experts in nuclear technology and weapon technology to conduct assault aerospace training for those with better physical conditions among the experts.

At this time, I can't care about any conditions or conditions. I can only stand up from the dwarf and solve the problem first.

Whether or not the asteroids can be stopped has been linked to the survival of all human beings. Under this premise, personal safety is not at all considered by the upper echelons. Anyway, no matter which country there is, there is no shortage of patriots who volunteer to die for the country.

The combination of the space shuttle and the electromagnetic gun, and how to install the electromagnetic gun and the reactor will take time to solve, but time waits for no one. Although the weapon platform has not yet lifted off, other materials have been in place one by one after more than a week of intensive preparations. Sent to space one after another.

Every day since then, we can hear the news of the launch of the launch vehicle. The launch vehicles launched by China, the United States and Russia alone account for one-third of the total number of launches.

The launch process was not all smooth sailing. Due to rush work and quality problems, one rocket in India and Japan exploded during the launch process, destroying a lot of materials. Fortunately, the carrying capacity of these two rockets is not strong, and when the launch plan was formulated The redundancy of materials has been considered, so the normal implementation of the plan has not been affected.
