Half-immortal civilization

It’s Father’s Day, I wish all the fathers in the world happy o(n_n)o haha~ For the master company, this may be the last big meal in the space age, but it’s still full; in the future, it seems that there is nothing special It can be widely spread throughout the global business.

The master company searched for some profits, and then the country's personnel entered the field, opened a port, lowered a tariff, and canceled some measures to ban China... Then the master company received various feedbacks from the country, and everyone did more at one stroke Yes, to benefit together.

In addition, the behavior of the master company asking for cultural relics has made the people of the country a little excited, and what is even more exciting belongs to the fields of archaeology and ancient culture research.In fact, under the influence of the master company, over the years, Huaxia's ancient culture research organizations, one after another, have revitalized Huaxia's ancient culture.What's ingenious is that Huaxia's researchers actually found inspiration from Huaxia's ancient culture, and under the influence of the technology of the master company, they developed another technological path.

Therefore, the return of cultural relics, especially a large number of returns, made Huaxia extremely excited.It's a pity that these returned cultural relics are the private property of the master company; fortunately, the master company promised to open them to Chinese citizens for free.

On the other hand, the master company is already preparing for the space mirror plan.However, this matter is almost entirely in the charge of the Space Environment Department, including various calculations, the development of related technologies, and so on.

Different from general aerospace equipment, the space mirror project this time is actually two plans. One is to use a large number of reflectors on the back of the earth to reflect sunlight back to the earth. A large number of reflective mirrors are distributed in a hemispherical shape and wrapped around the earth. Inside, the part facing the shadow of the earth needs to be vacated, because there is no sunlight here; according to the existing demand on the earth, at least about 24 million square kilometers of reflective light are needed Mirrors, or reflective films; and about 2000 million square kilometers of sun visors.These visors must be mesh and cannot completely block out the sun.It is necessary to ensure that the shaded area not only has enough light, but also cannot be too hot or bright, and keep the light at two degrees in the morning when the sun just comes out.Only in a small number of lifeless ice sheets, such as high mountains, will completely block the sun.

This is a huge project, especially if these two large objects must always be kept in a straight line with the earth and the sun, which requires a powerful engine to adjust their positions in space at any time, otherwise these things will soon become space objects. of free floaters.

Under the guidance of Zhong Yuanxing, and the comprehensive consideration of the corresponding scientific data and the convenience of management, the area of ​​each reflector is about 10 square kilometers, and the distance between two adjacent reflectors is not equal. Between 1 kilometers, and can be adjusted with each other; but for the sun visor, the master company used a small trick to install its own photovoltaic cells with other people's funds.This is not just a small amount of photovoltaic cells on the reflector to support self-use; but all the sunny sides must be installed with photovoltaic cells!It is necessary to turn this place into a power plant of the master company in space.

These sun visors are between the earth's equator and the sun, with a diameter of about 4000 kilometers, directly covering the part of the earth that is most severely scorched by the sun. The design adopts the distribution of blanks and sun visor intervals. It can block 12% of the high-altitude sunlight, and the minimum can be adjusted to [-]% of the sunlight.

In addition, sun visors are set up separately in places such as the North and South Poles, some deserts in China, and some deserts in Australia that exceed the coverage area.

However, the current project volume is very large, and the master company can only do it step by step.But the first point is to block the light of the desert, increase the exposure time of jungles and large cities, and restore the atmosphere as soon as possible. This is the worker's job.The positioning of a large city is a general large city with a population of one million, a large city with a population of 500 million, and an international city with a population of 1000 million.Internationalized cities are given priority, because the lighting and other things in these cities cost the most.

Compared with building a space base, restoring the earth's environment is more important, especially when the construction of the space base has recently entered the stage of refinement. The two existing Rising aircraft can be transferred in a short time to provide two reflective sun visors for space. service.

The first wave of installation is a reflector, which will be placed around the earth to reflect back the sunlight that does not hit the earth, increasing the time of light on the earth.Because the reflector uses a small amount of photovoltaic cells (for personal use) and a large amount of aluminum foil, it is supported by a plastic plate with holes, and then an aluminum profile is used as a bracket. The excellent design makes the weight very light, under the premise of ensuring good quality , the average weight per square meter is only 1.5 kg.

It's just that these things are still sent to Huaxia's space station for assembly before being delivered to the designated space location.But in this way, 150 tons of reflective film and 120 tons of sun visors can be transported to space at one time, because the sun visors are attached with photovoltaic cells, so the weight is much heavier.Even if it is because the master company and China's national construction use a large number of photovoltaic cells to promote industrial upgrading; but the current photovoltaic cells are still about 5 kilograms per square meter.Of course, it is also possible to use the thin-film battery used in satellites, but the cost is too high to be universal.

Therefore, the two planes can transport 0.1 square kilometers of reflective film and 0.03 square kilometers of sun visors to space on average each time.The rest of the tools, materials, personnel, etc., came to space with the Dream, Explorer or Flying space shuttle.

The whole world is fighting for the cause of space, except for those poor and backward countries waiting to die.It seems that everything is thriving; although humans have paid a high price for this.

However, God always likes to joke; to be precise, human technology cannot guarantee that spaceflight will be 100% accident-free.No matter which country it is, there have been countless accidents of various kinds before the current technology has been developed.

And this time, it's Russia's turn!

A large number of launch vehicles are used, especially the propellers of launch vehicles can be recycled; in order to save costs, Russia even pushed the recycling technology to the pinnacle of the world.But metal has a term called: metal fatigue.The core temperature of the launch vehicle is as high as 3300 degrees or more. Without special materials, steel will melt.Fortunately, such a temperature is quickly discharged from the thruster, and then filled with cold fuel.But such a harsh working environment has gradually overwhelmed the propeller.

However, in recent years, in order to make up for the disadvantage of not having enough space shuttles, Russia has used a large number of propulsion rockets, and the rocket propellers must be recycled.Under such conditions, finally today, April 4st, a problem occurred!
It's just that the time when the problem happened is really a bit--what a coincidence!

When the propeller was about to disengage, finally a propeller exploded due to the unbearable weight.A large amount of liquid hydrogen and oxygen caused an explosive power comparable to that of a small nuclear warhead, and the explosion occurred more than 200 kilometers above the ground.The explosion directly disintegrated the Russian transport module.However, under the action of inertia, coupled with the explosive thrust of the explosion, more than 300% of the fragments of the transport cabin were erupted into a low-earth orbit of 500-3 kilometers in space.Tens of thousands of fragments move unscrupulously here, some faster than [-] kilometers per second, or even seven or eight kilometers; slower ones are much faster than bullets.

It’s so hard to die, now [-]% of the space bases, satellites, facilities, etc. on the earth are in low-Earth orbit!

When Russia urgently notified the whole world of this information through the public channel, the whole world fell silent in an instant! ! !
