Half-immortal civilization

This time, Gaoshou's target is Ganymede and Callisto.Io is an active lava world. This planet is so active that its crust is very unstable. Its core is even hotter than the earth, and there are frequent volcanic eruptions of thousands of degrees. This is definitely a huge problem for the fiber web. The "baked" experience.And there is no water on it.Water is essential to transforming the planet into a hospitable place for humans.It is better to have more and float on the water than less.With the current human technology, it is really not afraid of a world full of water.Of course, there is another very important reason: Io is too close to Jupiter!And Jupiter's gravity is too great!
Ganymede and Callisto, although slightly larger, are far away from Jupiter, and their gravitational force is relatively weak, so they are easy to be dragged.Of course, more than half of these two planets are covered with frozen water; these frozen water are just good for Venus to cool down and replenish water.What's more, the addition of the two, plus the weight of the previous Ceres, is almost enough to make Venus not much different from the Earth.According to calculations, the gravitational acceleration of Venus can be increased to about 9.5; it is equivalent to the earth's gravitational acceleration of 9.8.

Such a planetary environment is really luxurious enough in space; in fact, at some point, someone has said this on the Internet: Venus is naturally the sister planet of the earth.However, some people have other speculations about the environment of the earth. The environment of the earth is too special-humans want to enter space, and there are resources on the moon; humans need to immigrate, and there is a Venus.These, what a coincidence!Of course, such remarks have been prevalent on the earth for more than 200 years. Since humans have observed space with modern means, there have been such remarks, so they have not attracted much attention from humans now.

After a month-long journey, the fleet has finally arrived at Jupiter again.Some expedition teams directly bid farewell to the team of the Master Company and flew to Europa; naturally, everyone has accepted the escort of the Master Company unknowingly—in other words.Unknowingly, the master company has become a solid backer in space.In other words, when the master company announced the abandonment of Europa, many people were rejoicing.A planet with such a strange life is an inestimable wealth.

Especially the promotion of life research has made this planet almost full of gold, which can well promote the development of early human space exploration.

The first target of the master company this time is Callisto.Compared with Ganymede, Callisto is much smaller, and its mass is almost a quarter smaller; in addition to the long distance from Jupiter, the cost of dragging Callisto, the time required, technical support, etc., Far more than doubled easily.on the periphery.Also a lot easier.

The huge flying formation just quietly suspended over Callisto, and the occasional ion wind that swept by made a protective layer of magnetic field that became elliptical under the influence of Jupiter dimly flicker.A powerful magnetic field enveloped the space with a diameter of more than 2 kilometers, providing protection for the fleet of the Master Company.

In the empty space, with the huge Jupiter at the back, the situation is changing.It almost fills half of the field of view; because of close observation, the dimmed satellites and rings make Jupiter a bit shy and soft in its wildness.

On the other side, through the porthole, looking at the cold world - Callisto.Mu Xinghai was making the final calculations.Of course, at such a historic moment, Li Canglan and Liu Haibo were all present, including their descendants: Mu Tianhe, Li Xinghui, and Liu Kaixing.

"The weight of Callisto is about 1076 billion tons, and the current speed is about 8202 meters per second. At this distance, if Callisto wants to escape Jupiter's gravity, the speed must reach at least 12 kilometers per second (not rigorous), However, to accelerate this 1076 billion-ton object from 8 kilometers to 12 kilometers per second, the energy required is enough to keep us busy for thousands of years. Obviously, if you want to drag Jupiter away only by the power of the spacecraft Four, is impossible.

But it is very ingenious that we really have a helper and an ally, that is: the sun!

According to calculations, if we use the gravity of the sun, we can drag Callisto away in only one year, and after about two years, it will fall to Venus as planned.

That is, everyone will have to work hard for a year; this process will be a boring, rigorous, and repeated work.And this will be the most difficult year since the master company entered the space development.For a year, we cannot relax in the slightest.If there is a slight deviation, all previous efforts may be wasted. At that time, Callisto will not only be unable to land on Venus, but may also destroy the earth. "

'Relax, Captain! '"Uncle..." "Dad..." The various titles were in confusion.

"Very good." Mu Xinghai was very satisfied with everyone's attitude. "After this matter is successful, I will apply to the boss to give you the rewards you deserve. Of course, I hope that this reward will be after completing all the plans for Callisto and Ganymede. Now, these core personnel are all For those who have practiced at the sixth level or above, staying in space for three to five years, there is actually no problem at all; of course, I don't want to see any problems.

The company usually gives everyone a lot of benefits, and I don't want to see anyone lose the chain. "In the end, Mu Xinghai's voice was cold, and the aura of a Jindanqi master suddenly erupted.

"Three years! It's only three years at most! We have passed the most difficult 30 years! Next, it is time for us to create our own era and glory. Everyone, after the construction of Venus is completed, I think that within a few hundred years There will never be such a wonderful event again, we can't miss it!

People, when they come to this world, always have their own mission.I think it is our mission to transform Venus and make Venus a second paradise for human beings. "

"Don't miss it! Don't miss our mission!" All the people answered loudly, their eyes filled with a sense of mission glory.

"Now, act!"

With an order, tens of thousands of astronauts began to get busy. More than 5000 people are resting, and more than 5000 people are busy.For the next three years, everyone will work on this painful two-shift system.

A huge net was cast down and slammed on Callisto. There were 200 rope ends extending over 4000 kilometers around the giant net. In the middle was a large net with a diameter of about 5000 kilometers. The rope was 30 centimeters long. Fiber cord!

The ropes made of olefin fibers are only about 30 centimeters in diameter; but in such a rope, there are more than 30 billion tiny fibers entangled together.This gray and seemingly inconspicuous rope represents the most dazzling crown among fiber materials in the world today.Fiber cost of the same weight.Already more precious than rare earth metals.The carbon fiber of the hair is enough to lift hundreds of tons of gravity.

In order to drag Callisto and Ganymede this time, the master company mobilized the company to produce a total of 100 such ropes.The density of these fibers is around 1.5. 100 such ropes are nearly 200 tons; some people describe it this way, this [-] tons of carbon fiber is more expensive than the [-] spaceships of Gaoshou Company!

To weave such a large net, of course, it is impossible to weave it in advance, but weave it on the spot in the sky, and the fabricated shuttles are top-notch space shuttles.

Like a busy bee, the space shuttle is constantly shuttling between the spacecraft. The space shuttle of about 30 meters, in front of the huge spacecraft, is like a bee in the eyes of adults.The ratios are too different.

It took half a month to compile a net; the main thing is to fix the nodes between each rope, which is a very tedious job.There are more than 2 intersections between one hundred ropes; in order to ensure the load bearing of the giant net, it is not simply a matter of simply lapping them together.Instead, it has complex clasps. From a distance, this giant net looks like an oversized Chinese knot.

In space, there is no such thing as "black sky and white night", only the eternal and lonely starry sky.

"Get ready!" Mu Xinghai's eye-catching boss, today is the time that will be recorded in history.Although it is said that the master company already has sufficient data and data on dragging space objects.But the biggest ones before were Ceres and Vesta.The rest are all small meteorites, and the big ones are about a hundred kilometers away.Perhaps, an asteroid with hundreds of kilometers is enough to weigh hundreds of millions of tons.However, compared to the current behemoth, it is really not enough.

1076 billion tons!This is a number that ordinary people have no concept of at all.Because, it is too big!Like we said.So-and-so weighs 70 kilograms—very healthy data; so-and-so weighs 100 kilograms-a little fat.The stone weighed ten tons—very heavy.A ship with a load of 50 tons—it looks very big; a giant ship of [-] tons—it looks big; a giant ship of [-] tons—it still looks big.A mountain weighs tens of billions of tons—that's a huge number!
Yes, step by step, everyone will feel: this "number" is so big, not how big this object is.The reason for this feeling is that it has exceeded the imagination of the brain!

but.Now the expert company is going to do something like this: drag a planet whose weight is beyond the imagination of ordinary people from the Jupiter system, and then let it hit Venus to complete the transformation of the planet by the expert company!
Therefore, this matter required Mu Xinghai to sit in charge in person; but even Mu Xinghai felt a little guilty.This matter, the power of human beings, can only play a guiding role; more is-to end the natural power of the universe.Now the power of human beings is still too small!
When Callisto is in the middle position between Jupiter and the sun, it is an opportunity for master companies.Taking advantage of this opportunity, Callisto's orbit can be slightly altered.Once, twice, tens of hundreds of times, Callisto will be dragged away from Jupiter's gravitational circle!

Callisto will revolve around Jupiter in about 16.689 days; with the role of the master company, the time for one revolution in the future will be about 17 to 18 days on average.In other words, this time, the team only had one day of homework every seventeen or eight days.Only on a certain day, when Callisto is between Jupiter and the sun, is the ideal time to work.

Everyone stared at the dashboard and listened carefully to the commands in their ears.In space, there are too many things that cannot rely on machinery and computers, and need to be executed manually by humans.Only in this way can we ensure that there will be no mistakes at all.This is mainly because the space is complex, and the data needs to be recalculated before each execution.Otherwise, it is really a small mistake and a thousand miles away.No, in space, a small error can enlarge the distance between Jupiter and Venus to a gap of millions of kilometers!This gap may allow Callisto, which was planned to hit Venus, to eventually hit the Earth.This may be small, very small, but it is possible! ! !
Some accompanying scientists are nervously calculating, the advanced atomic clock is measuring space with almost absolute precision.This is the craziest plan since the birth of Master Company - sniping Venus; and dragging Jupiter's satellite is the most difficult plan in this plan.In contrast, whether it is Ceres or Vesta, they are all "planets"-revolving around the sun, and their motion is much simpler.

But Callisto is a satellite, one of four huge satellites, and its trajectory in space is extremely complicated.And every seventeen or eight days, you have to change a little state by yourself, and in the complex space environment (Jupiter + Callisto, Callisto and other satellites, Jupiter + sun, Callisto + sun) are magnified by geometric multiples .It brings constant challenges to the work.

A little sweat oozed from Mu Xinghai's palm.How long has it been since you came to the master company and achieved success in practice?Mu Xinghai had almost forgotten.But at this moment, I once again found the passion to fly to space for the first time!

Naked is more stressful
