271 Weight Gain Mars
However, it is impossible to say that there is no harm to Mars at all. There are also a large number of impact craters on Mars, which are damage caused by the impact of various meteorites and asteroids.
In fact, there are not many Blue Stars that have been hit by such impacts, but it has a moon that acts as a barrier, so most of the damage has been borne by it.
In addition, due to the prosperity of various plants on the Blue Star, the already high air density brings weathering and corrosion from the moist air, which also makes those impact craters, unlike those on the Moon and Mars, look like scars. on the ground.
After the impact, the kinetic energy generated by the impact and the meteorite fragments will remain on Mars, which may trigger earthquakes throughout Mars, as well as strong geological activities, such as large volcanic eruptions.
Geological movements throughout Mars will obviously cause huge damage to some detectors launched by Blue Star, and this damage may be completely irreversible.
For example, when a volcano erupts, it will inevitably form volcanic ash and harmful gases throughout the entire Martian atmosphere.
This makes the Mars rover, which relies on solar energy to supplement electrical energy, almost lose its source of energy.
However, this may not be a bad thing for Mars. The large amount of gas brought by volcanic eruptions should greatly replenish the density of the Martian atmosphere.
Facts have proved that the reason why Mars' atmosphere is thin is largely due to the fact that Mars' magnetic field is very small. This is too weak for a planet whose rotation speed is almost the same as that of a blue star.
Of course, this is also related to the fact that Mars is too cold. If such a cold surface is transmitted, it is estimated that the thickness of the crust is already several times thicker than that of Blue Star.
Don't forget that the diameter of Mars is only half that of a blue star, which results in less mantle, poor fluidity, and a smaller core, which cannot generate a sufficient magnetic field.
Obviously, in addition to adding weight to Mars, we also need to increase its speed.
Just increase the rotation speed.
Obviously, it is not easy to increase the speed of Mars. Such a huge planet has basically fixed its angular speed.
Even Yang Qing has no idea, because the best way to increase the speed of Mars is to use external force. Although the crust of Mars is very thick, its small gravity makes its crust structure very loose and cannot support its rotation at all. Accelerated structure and thrust.
Although there are many ways to apply external force, such as electromagnetic field, or simply force field acceleration.
However, it is not that simple to cover a large planet with a diameter of nearly 7,000 kilometers. The electromagnetic field or force field is not that simple, because the force field is very large and the intensity is very high. Otherwise, it would not be able to reach a mass of 6.417 times 10 twenty-three times. The planet weighing one kilogram is rotating at an accelerated speed.
It's not impossible, but it requires too much energy, so much that Yang Qing needs to build several Dyson rings for it.
At Yang Qing's current production level, the construction period for such a Dyson ring may take hundreds of years.
Anyway, there is more than one way to transform Mars, and for the time being, he does not need to carry out such a long-term project.
Another path Yang Qing chose is to bombard the divided asteroid at a certain tilt angle to Mars. In this way, the kinetic energy of the asteroid still enters Mars bit by bit, and part of it, It can also be used to increase the speed of rotation.
Although this kind of power is actually only a drop in the bucket, or even smaller than a drop in the bucket, it cannot support its sufficient quantity. At least within the next few decades, there is no possibility of stopping this project of increasing the weight of Mars.
Although a few decades is almost the best years of an ordinary person, it is already extremely fast to transform an Earth-like planet in just a few decades.
You must know that it has only been two hundred years since the first industrial revolution. It was only sixty or seventy years ago that humans were able to leave the Blue Star and explore the universe.
Sixty or seventy years ago, in the 1960s and 1970s, it was really an era of technological explosion. Artificial satellites, manned spaceflight, interstellar exploration, lunar landings, and electronic computers all began to develop during this period. , probably the only regret is that the Chinese have almost completely missed this period, so that after the opening up, they have clearly felt their backwardness.
Although it would take decades to gain weight on Mars.
However, in the past few decades, Yang Qing and Xiao Ai have not waited in a vacuum. The work of adding weight and temperature to Mars can be carried out at the same time.
Volcanic eruptions caused by weight gain will release a large amount of gas. Without the protection of a magnetic field similar to the strength of a blue star, these volcanic gases, which can greatly increase the density of Martian gases, will be blown away by the solar wind again.
Every year, the total mass of gas blown away by the solar wind or actively escaping from blue stars exceeds several thousand tons, which is almost the mass of a large asteroid.
To increase magnetic field protection for Mars, it is necessary to establish an electromagnetic field controller, which is a large platform built in the outer space of Mars.
There will be many such large-scale platforms, integrating functions such as sunlight emission, solar power generation, gravitational talisman array, electromagnetic control and so on.
In fact, if the synchronous orbit of Mars is not too low, with an altitude of only more than 10,000 kilometers, only a few platforms in fixed orbits can cover the entire Mars.
Precisely because the synchronous orbit is too low, not even much higher than Olympus Mons, the highest peak on Mars, the ash from volcanic eruptions may even contaminate them, so a platform cannot be built at this location.
However, high orbit also has its own benefits. A high orbit more than 50,000 kilometers away from Mars may require a little more large-scale platforms, but it also increases fault tolerance. Not only will more sunlight be reflected to Mars, but the magnetic field of Mars will also be arranged. It is more suitable and will not allow cosmic rays to reach the ground.
In addition, it is also found that towing and dividing asteroids requires a large number of spacecrafts. They need to make the gravity engines larger and more efficient, and they also need one or several large shipyards built in the universe.
There are many advantages to building a dock in the universe. For example, there is no gravity, and there is no distinction between up, down, left, and right. Then there is no need for large lifting machinery. Any robot can pull the large keel of the spacecraft back and forth.
There is also no air in the universe, so you don't have to worry about welding defects such as pores when welding materials, and you can use welding operations with confidence.
Of course, there are many shortcomings. For example, the extremely low temperature in vacuum brings great inconvenience to the selection and processing of materials in the universe.
However, this is not particularly difficult for Xiao Ai. After several years of actual operation, the robot under her control has made enough improvements for the vacuum environment and the frequently sudden temperature changes.
