The Return of the Black Technology of Immortal World

The theoretical construction of towing asteroids has actually been completed a long time ago. Even the ropes used to tie asteroids have been officially produced, and the quantity is enough for more than a dozen spacecraft.

And this rate is still increasing. After all, as long as the production process is mastered, and carbon is one of the most abundant elements in the universe, there will be no shortage of raw material supply.

Traction of light speed does not need to be considered at the moment, because this thing consumes too much energy.

Maintaining such a large force field itself requires a tens of millions of kilowatt-level reactor, supplying more than 50% of the energy, plus the energy needed to change the orbit of the asteroid.

It's not that it can't be done. After all, relying only on the wind pressure of the solar sail and the weak thrust, a specially-made spacecraft can be raised to a flight speed of more than one thousandth of the speed of light, which is much faster than all previous spacecrafts. .

Although such a speed requires a long period of acceleration, the same is true for using a force field to pull an asteroid. It will take more than seven years to successfully pull an asteroid.

The captured asteroid is not only smaller in diameter than the asteroid pulled by the rope, but also slower, so it is naturally selected.

Of course, if one day there is a breakthrough in reactor technology and energy utilization is more efficient, tractor beams may not be put back on the agenda.

So under Yang Qing's command to fully let go, the entire moon suddenly began to boil.

After three years of continuous surveying, most of the minerals on the moon with a depth of more than 300 meters have been explored and understood. In the past, there was no need for so much material, and there was no need to fully exploit it, but now it is different.

There are more than a dozen platforms around Mars that increase gravity and magnetic fields, as well as more than 10,000 spacecraft used to tow asteroids, all of which require a large amount of metal material for processing.

So within an hour of Yang Qing's decision, more than a hundred excavation teams departed from the Moon Palace Base and headed to their respective locations on lunar vehicles.

And as time goes by, the number of such teams continues to increase.

The first thing each team does after landing is to determine the excavation scope and lay down dozens of square kilometers of solar panels.

Although controllable nuclear fusion has been successfully miniaturized, the core chamber of a 200,000-kilowatt reactor is only slightly larger than a human fist, and the entire unit is only the size of a V8 engine.

However, although the moon is rich in certain resources, such as metals, the content of fusion materials is actually not much.

Although according to the explorable reserves, the reserves of helium-3 in the lunar soil can be used by humans in the previous world for hundreds of years, but when averaged over the entire lunar surface, it is impossible to say how rich the reserves are.

Another source of fusion materials is water.

Not used for water on Blue Star, the water here is mainly water ice. Due to the influence of cosmic rays, the amount of deuterium contained in it accounts for 20% of water molecules.

Although the requirements for deuterium fusion are almost the same as those for helium fusion, neutrons will also be emitted, which is a great hazard to the controllable nuclear fusion of the Blue Star route.

But for the controllable nuclear fusion route of the Moon Palace Base, there is no difference.

A single free neutron will completely decay within thirty minutes. Before that, it cannot escape the huge pressure brought by the pressure array and is bound in the middle of plasma with a temperature exceeding 100 million degrees.

But the amount of water ice on the moon is also very limited, and even less deuterium can be extracted.

In order to tow asteroids, powerful power is needed, so each spacecraft is equipped with a controllable nuclear fusion reactor that can continuously add fuel.

The mass of Mars is only 11% of the blue star, so it is naturally impossible to increase it to the mass of the blue star. In that case, the original core of Mars is too small to absorb so much mass that has been pieced together. The result will naturally be that it will fall apart. There is no chance of saving.

Yang Qing's goal is to increase the mass of Mars to 20% of the moon. If that is not possible, then increase it to 15%. After all, an increase of 9% is already a very dangerous mass and requires It takes a long time to be fully digested.

The total mass of Mars is 6.429 times ten to the power of 23 kilograms, which means that an additional mass of 5.26 times ten to the power of 23 is required.

Based on the calculation that an asteroid with a diameter of one kilometer has a mass of about 5 billion tons, more than 10 million such asteroids would be needed.

However, after searching the entire asteroid belt, there are only a few hundred asteroids with a diameter of more than one kilometer, including dwarf planets like Ceres.

Vesta is actually a type of dwarf planet. After all, it is too big to be towed out of its orbit, unless Yang Qing is determined to spend a thousand years adding hundreds of towing spacecraft to it.

Therefore, Yang Qing has always been very easy-going about adding weight to Mars. He hopes that the entire process will be completed within twenty years, so how much mass will be added to Mars by then is still a mystery.

The technological progress of the Moon Palace Base can be regarded as rapid. In just three years, the speed of the spacecraft can reach one-tenth of the speed of light. The only disadvantage is that it takes nearly three months of acceleration to reach such a speed.

Maybe three years later, a gravity control engine with greater thrust will be invented. At that time, acceleration to one-tenth or even higher speed can be controlled within a month.

At that time, even at the maximum distance between Mars and Blue Star, the spacecraft could reach it within two months.

Although the maximum distance between Mars and Blue Star exceeds 400 million kilometers, it will not take more than four hours at a top speed of 30,000 kilometers per second.

The time it consumes is spent accelerating and decelerating on the road.

At that time, it will become possible to search for asteroids in the Kuyinbo belt and bring them back.

Note that this is only a possibility. Asteroids are not like our own spaceships. They have no energy cover. Except for some individual asteroids, they are more like an aggregation of a bunch of rocks. The acceleration of the traction is too great.

Likely to make them fall apart.

Using conventional speeds, their speed is too slow. Across a distance of 4 billion kilometers, even if the speed reaches the third cosmic speed, it is only 16.7 kilometers per second. It will take nearly eight years to enter the orbit of Mars in the inner solar system. .

This does not include the search and deceleration time, because even if we see the simulation demonstration of the Coinber Belt on the star map, there are countless asteroids, dwarf planets and comets.

The Kuiper Belt is actually a vast area surrounding the sun and outside Neptune, between more than thirty astronomical units and fifty astronomical units.

This distance already includes the seven major planets in the solar system. Pluto, as we know it, is also located here after being downgraded.

It seems dense here, but in fact it is extremely empty, because this sphere is so big that it is possible not to see a single celestial body within a distance of hundreds of millions of kilometers.
