Vol 3 Chapter 283 weight gain goal

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

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

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

To maintain such a large force field, a 10-million-kilowatt-level reactor is required to supply more than 50% of the energy, plus the energy required to change the orbit of the asteroid.

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

Although such a speed needs to be obtained after 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 naturally becomes the selected one.

Of course, if one day, the reactor technology gets a breakthrough and the efficiency of energy utilization is higher, the tractor beam may not be put on the agenda again.

So under Yang Qing’s order to fully let go, the whole moon suddenly boiled.

After three years of uninterrupted surveys, 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 many materials, so there was no need to fully mine them. Now it is different.

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

So within an hour of Yang Qing’s decision, starting from the Moon Palace base, more than a hundred excavation teams had already taken the lunar spacecraft to their respective locations.

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

The first thing each team does when they land is to determine the scope of the excavation and lay down tens of square kilometers of solar panels.

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

However, although some aspects of the moon’s resources are very rich, like metals and the like, the content of fusion materials is actually not much.

Although according to the exploreable reserves, the reserves of helium-3 in the lunar soil can be used by humans in the last world for hundreds of years, but if it is averaged over the entire lunar surface, it is not enough to say how rich the reserves are.

Another source of fusion materials is water.

It is not used for the water on the 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 the water molecules.

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

But for the controlled nuclear fusion route of the Moon Palace base, there is no difference.

A single free neutron will completely decay within 30 minutes. Before that, it can’t get rid of the huge pressure brought by the pressure symbol array, and is bound in the middle of the plasma with a temperature exceeding 100 million degrees.

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

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

The mass of Mars is only 11% of that of Blue Star, so it is naturally impossible to increase the mass of Mars to that of Blue Star. In that case, the original core of Mars is too small to absorb so much assembled mass. No chance of saving.

Yang Qing’s goal is to increase the mass of Mars to 20% of that of the moon. If it cannot be achieved, then it will be 15%. After all, an increase of 9% is already a very dangerous mass. It takes a long time to fully digest.

The total mass of Mars is 6.429 times ten to the power of 23 kilograms, which means that the mass of 5.26 times ten to the power of 23 kilograms needs to be added.

Based on the calculation of an asteroid with a diameter of one kilometer and a mass of about 5 billion tons, more than 10 million such asteroids are 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 pulled out of its own 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 easygoing about adding weight to Mars. He hopes that the whole process will be completed within 20 years, so how much mass Mars will be added by then is still a mystery.

The technological progress of the Moon Palace base is also changing with each passing day. In just three years, the speed of the spacecraft can reach one-tenth of the speed of light. The only disadvantage is that it needs nearly three months of acceleration. UU Reading www. uukanshu.com can achieve such a speed.

Maybe wait until three years later, a gravity control engine with greater thrust will be invented. At that time, it can be accelerated to a tenth or even higher speed, and it can be controlled within a month.

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

Although the maximum distance between Mars and the blue star exceeds 400 million kilometers, but at the extreme speed of 30,000 kilometers per second, it will take no more than four hours.

The time it consumes is spent on acceleration and deceleration on the road.

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

Note that this is only a possibility. Asteroids are not like their own spaceships, which have no energy shield. Except for some individual asteroids, they are more like a pile of rocks. The acceleration of the traction is too large.

Likely to make them fall apart.

Using the conventional speed, their speed is too slow, spanning a distance of four billion kilometers, even if the speed reaches the third cosmic speed, it is only 16.7 kilometers per second, and 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 simulated Kuymber belt on the star map, there are countless asteroids, dwarf planets and comets.

The Kuiper belt is actually a vast area around the sun, outside Neptune, between more than 30 AU and 50 AU.

This distance already includes the seven planets of the solar system, and the well-known Pluto is also located here after being downgraded.

It looks dense here, but it is actually extremely empty, because the sphere is so big, it is possible that within a distance of hundreds of millions of kilometers, there is not a single celestial body.
