Other methods have been proposed by the participants, including painting the asteroid, installing solar sails, reflecting mirror arrays, and even sending people to install nuclear bombs on the asteroid.
However, these plans are not as simple as they seem. It is not difficult to apply a layer of paint on the surface of an asteroid. You can directly launch the barrel containing the paint as a cannonball and hit it on the asteroid to achieve the effect of spray paint.
The problem is that the thrust generated by this method is pitifully small, and it will take several years to change the orbit of the asteroid.
The same is true for reflector illumination. Without enough time, the asteroid's orbit cannot be changed at all.
Solar sails can be effective in a short period of time. Even if the thrust generated by the solar sail is very large, the impact of cosmic objects is really just a hairsbreadth away. As long as a little external force is applied to the asteroid, its orbit will change drastically.
The deflection is enough to push the asteroid away from the impact orbit.
However, the flight speed of this group of asteroids is as high as 200 kilometers per second, and it is still gradually accelerating. It is impossible for any aircraft built by humans to catch up with the speeding asteroids.
Sending people to an asteroid to install a nuclear bomb is simply an impossible task.
It is not impossible to launch a solar sail head-on, but with 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. It will explode on the spot like a cannonball.
When the discussion reached this point, the venue suddenly fell into an eerie silence. One of the participating experts woke up from a dream and asked, "Can an explosion push away an 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 will probably produce a
A 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!"
"Twenty-one kilometers is too little, and expanding it a hundred times won't be enough."
"Then increase the number of hits!"
"Ladies and gentlemen, we only need to consider the feasibility. Let the politicians decide what to do."
"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, then communicated with each other, and finally determined 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 shells are 127 mm warheads - note that they are warheads and not bullets. Anyway, there is no air resistance in the universe. As long as it can be launched from the electromagnetic orbit, no matter what
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 to serve as ammunition.
The electromagnetic gun needs enough electric energy to drive. If traditional solar panels are used to provide electric energy, the area required is too large. Just transporting the panels to space will take up a considerable part of the transportation capacity. This is an unbearable result no matter what.
.
To this end, China 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 never obtained conclusive evidence.
If it weren't for the fact that he couldn't find a more suitable reactor, Brother Yi would definitely not be willing to bleed.
In fact, micro-reactors are the most suitable reactors for use in aerospace engineering, but the output power of micro-reactors is too low to drive electromagnetic guns. The number of multi-reactor linkages is too large, and the time is too short to manufacture them, so we can only
The next best thing is to build two liquid metal piles on top.
The electromagnetic gun must be installed on a stable weapon platform, and 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 took action to prepare for the installation. Top experts from various countries worked as quickly as possible to design the connection device between the rail gun and the space station.
However, the space station is not a space battleship. After calculations, it was found that the vibration and recoil caused by the continuous launch of the electromagnetic gun will not only affect the normal posture 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 electromagnetic gun cannot be installed on the space station anyway!
For this reason, the five major countries once again launched emergency consultations, but only China, the United States, and Russia spoke at the meeting. Britain and France, which were already in their prime, had the good sense to keep their mouths shut.
The result of the discussion was that a weapon platform must be customized for the electromagnetic gun. Countries and regions around the world with aerospace capabilities use disposable spacecraft, which cannot be used as a weapon platform at all. Only the Americans have a unique space shuttle.
The Americans had to pull the long-retired space shuttle out of the museum and recruit technicians as quickly as possible to conduct comprehensive maintenance. They did not ask for how many times the space shuttle could be used, but only wanted a successful launch, even if it was thrown directly after the mission.
It doesn't matter in the universe.
Worried that the space shuttle might crash during launch, the United States pulled out four retired space shuttles at one go. However, according to the launch plan, these retired space shuttles will not carry important materials such as electromagnetic guns or reactors during launch 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 various countries have tried their best to seal it as a whole and minimize the difficulty of combination, the combination of the three is still not a problem that can be solved by just connecting a wire. It must be guided by professionals on site.
To this end, various countries urgently convened experts in nuclear technology and weapons technology to conduct assault space training for those in good physical condition among the experts.
At this time, I no longer care about the conditions or unconditional conditions. I can only try to get the taller one out of the short ones and solve the existing problems first.
Whether or not the asteroid swarm can be blocked has been linked to the survival of all mankind. Under this premise, personal safety is not considered by the higher-ups at all. Anyway, no matter which country, there is no shortage of patriots who are willing to sacrifice their lives for the country.
The combination of the space shuttle and the electromagnetic gun, and how to place the electromagnetic gun and the reactor will take time to solve, but time waits for no one. Although the weapons platform has not yet taken off, other materials have been put in place one by one after more than a week of intense preparations.
are sent to space one after another.
Every day since then, we can hear the news of the launch of launch vehicles. Launch rockets launched by China, the United States and Russia alone account for one-third of the total launches.
The launch process was not smooth sailing. Due to rush work and quality problems, a rocket from India and Japan each exploded during launch, destroying a lot of supplies. Fortunately, the carrying capacity of these two rockets was not strong, and when the launch plan was formulated
The redundancy of materials has been taken into account so that it does not affect the normal implementation of the plan.
