The Return of the Black Technology of Immortal World

Although the asteroids orbiting the sun in the asteroid belt are all very fast, at least faster than the revolution speed of the blue star, they are in constant motion around the sun most of the time.

In other words, as long as an external force is applied to it, even if the force is small enough, its orbit can be changed.

In this way, a spacecraft, relying on the propulsion of its engine and continuous towing, can tow an asteroid weighing tens of millions of tons.

There is also something to be careful about when towing. You must choose the direction of the asteroid's rotation axis to pull, so that the cable will not be stirred up.

The asteroid is tied up like a pig, then a long towing rope is extended and fixed to the hook at the tail of the spacecraft.

Because this hook is a rotatable part and has to bear almost all the pulling force, the strength requirements are also extremely high. In this part, Xiao Ai specially mixed a large amount of spiritual metal.

Once these tasks are completed, we can officially start changing the asteroid's orbit and pull it toward Mars.

This work is usually completed by the cooperation of two spacecrafts. After selecting a suitable asteroid, it can be reported to Xiaoai, and she will calculate the orbit to reduce the possibility of collision with other asteroids.

Even the amount of propulsion power exerted by the two spaceships is all part of Xiao Ai's calculations.

It can be said that once the asteroid is successfully stabilized, the remaining work will be completely taken over by Xiao Ai. This is also the confidence for her to fully operate. She can complete all tasks using only robots to drive the spacecraft.

In fact, if it weren't for the various accidents that might happen in the universe, she wouldn't even have to equip a robot crew, because in her opinion, the spaceship is actually a large robot.

It also has its own mechanical arms and its own brain, and even because of its size, its central computer is much more powerful than ordinary robots.

Because they are all non-working fluid engines controlled by gravity, there are no thrusters like ordinary rockets, or hot gas or plasma ejected by plasma electric thrusters.

Therefore, the two spacecraft can be easily connected in series to provide enough pulling force for the asteroid behind them and change its orbit.

In fact, this kind of towing is similar to the return capsule returning to Blue Star. After many orbit changes, it can successfully land on the ground.

Before the asteroid can successfully cross the orbit of Mars, it still needs to slow down.

Xiaoai wants a Mars that has gained weight, rather than preparing to crash it directly.

According to some conjecture, Mars in ancient times may have encountered such an impact, which led to earth-shaking changes in Mars where life may have appeared in ancient times.

Although Mars is inherently unviable, if another large impact knocks out all the material in the mantle, Mars may be torn apart, just like the asteroid belt between Mars and Jupiter.

According to some speculations, there was probably a large planet between Jupiter and Mars in the early days of the solar system, and the current asteroid belt is the product of its split.

How exactly did it split? Whether it was the gravitational pull of Jupiter, the impact of a large planet, or whether it was man-made damage, we still have no idea. After all, that era was too long ago, and there was no observation record.

If Xiao Ai doesn't want Mars to face the same fate, then slowing down the asteroid is an imperative action.

Originally, Xiao Ai planned to directly impact Mars with the captured asteroid, which would not only increase the weight of Mars and the kinetic energy of the collision, but also directly heat Mars. However, after many calculations, she still had to make changes.

However, slowing down asteroids, even using carbon nanotube materials, is a long process, because they orbit the sun extremely fast, at least faster than Mars.

But this way, her workload will be much less. She only needs to control the spacecraft and reduce its speed to a level similar to the revolution speed of Mars when it is approaching Mars. Then it will naturally be affected by the gravitational field of Mars. Capture, and then slightly modify the orbit to put the asteroid in the right position.

Of course, impact is inevitable, and it will still cause geological changes across Mars, causing extinct volcanoes on Mars that have been dormant for tens of millions of years to burst into life again.

The re-eruption of volcanoes can not only heat up Mars, but also bring the gas that is most lacking on Mars.

As a planet with an extremely weak magnetic field, Venus has a terrifying atmospheric pressure, which is probably caused by gases brought out by Venus' active geological activities.

Because lighter gases, such as hydrogen, oxygen and nitrogen, can easily fly to the top of the atmosphere and be blown away by the solar wind, so in volcanic eruptions, a large amount of carbon dioxide gas naturally falls to the top of the atmosphere because of its larger molecular weight. Lowest level.

There are no plants on Venus that can absorb carbon dioxide. As time goes by, the atmospheric pressure on Venus becomes more and more terrifying.

And because of the thick clouds on Venus, the amount of sunlight it can receive is no more than that of the Blue Star. Venus is more like an iron ball that is almost red-hot. Even if it blocks most of the sunlight it can receive, it will not be able to receive more sunlight. The cooling time must also be calculated in hundreds of years.

Because towing an asteroid and bringing it to Mars will take years, which is generally at least about five years.

This time is mainly consumed in slowing down the asteroid, so if you want to quickly build Mars according to Yang Qing's expectations, the transport team sent out at one time cannot be too small.

Fortunately, these spacecraft do not need to carry people, so the devices used to maintain human survival can be ignored.

The entire spacecraft, except for a central engine room, a fusion reactor, and two gravity control engines, does not need anything else.

The only space occupied here is the machine room and the fusion reactor, so the spacecraft can be made small enough, just over thirty meters long, and its mass will not exceed one hundred tons.

This is because it needs to drag the asteroid to slow down, which requires a certain mass, otherwise it can be made less than ten tons.

Of course, there is another way to drag an asteroid, which is the speed of light due to gravity.

The Moon Palace Base, which has basically mastered gravity, naturally found a way to realize the gravitational field.

That is, a certain area in the universe is covered with gravity to form a controllable gravitational anomaly area. Xiao Ai has improved it to the point that it can be placed on a spacecraft.

When an asteroid happens to enter this area, the spacecraft can exert an influence on it, such as a force in the opposite direction of revolution and an acceleration that changes the orbit.

However, the current coverage of the gravitational anomaly area is still very small, and it can only catch some asteroids or meteorites with a diameter of less than 500 meters.

However, this kind of technology represents the future. I believe that with Xiao Ai's research, its control range will soon exceed one kilometer or two kilometers.

In the future, it can even be developed into weapons. If the gravity of this gravitational anomaly area is strong enough, it can even become a black hole with an extremely short existence time.

Although it is necessary to turn it into a black hole, the current energy supply method is absolutely impossible. At least there is hope for a reactor at the level of annihilation of matter and antimatter.
