It's Father's Day, and I wish all the fathers in the world a happy o(n_n)o haha~ For the Master Company, this may be the last big meal in the space age, but it still makes me feel full; from now on, it doesn't seem to be anything special. The business can be widely spread all over the world.
Gaoshou Company collects some of the profits, and then the country's personnel come in to open ports, lower tariffs, and lift some bans on China... Then Gaoshou Company gets various feedbacks from the country, and everyone does more with one stone. Let’s make a profit together.
In addition, the master company's request for cultural relics has made the Chinese people a little excited, and the ones who are even more excited are those in the fields of archeology and ancient culture research. In fact, under the influence of the Master Company, China's ancient culture research organizations have revitalized China's ancient culture one after another over the years. What's clever is that Chinese researchers actually found inspiration from China's ancient culture, and under the influence of the technology from the master company, they actually developed another technological path.
Therefore, the return of cultural relics, especially the return in large quantities, makes China extremely excited. Unfortunately, these returned cultural relics are the private property of Gaoshou Company; fortunately, Gaoshou Company promised to open them to Chinese citizens for free.
On the other side, the Master Company is already preparing a plan for a space mirror. However, this matter is almost entirely handled by the Department of Space Environment, including various calculations, the development of related technologies, etc.
Different from general aerospace equipment, this time the Space Mirror Project 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. In order to ensure that the earth is illuminated by 24-hour sunlight, it is necessary to A large number of reflectors are distributed in a hemispherical shape, wrapping Outside the earth, the part facing the shadow of the earth needs to be vacated because there is no sunlight here. According to the current demand on the earth, at least about 100 million square kilometers of reflectors or reflective films are needed; and in addition there are There would be about 20 million square kilometers of sunshade. These visors must be mesh and not block out all sunlight. It is necessary to ensure that the shaded area not only has enough light, but also that the temperature and brightness should not be too high. Keep the light level at two degrees when the sun first comes out in the early morning. Only in a small number of lifeless ice fields, such as high mountains, will the sun be completely blocked.
This is a huge project, especially since these two large objects must always remain in a straight line with the earth and the sun. This requires powerful engines to adjust their positions in space at any time, otherwise these things will soon become objects in space. of free floats.
Under the guidance of Zhong Yuanxing, as well as the corresponding scientific data and the convenience of management, the area of each reflective panel is about 10 square kilometers, and the distance between two adjacent panels varies, ranging from 1 to 10 square kilometers. 100 kilometers, and can be adjusted mutually; but for the sun visor, the master company used a small trick to install its own photovoltaic cells using other people's funds. This is not just a small number of photovoltaic cells on the reflective panels to support personal use; rather, photovoltaic cells must be installed on all sunny sides! We want to build this place into a power plant in space for the Master Company.
These sunshades are located between the earth's equator and the sun, with a diameter of about 4,000 kilometers. They directly block the part of the earth that is most severely burned by the sun. The design adopts the distribution of gaps and sunshade intervals. As a unit, each square meter has a maximum It can block 12% of high-altitude sunlight, and the minimum can be adjusted to block 10% of sunlight.
In addition, separate sunshades are set up in places beyond the coverage area such as the North and South Pole, some deserts in China and some deserts in Australia.
However, the current project volume is very large, and expert companies can only do it step by step. But the first point is to block the light in the desert, increase the exposure time in jungles and large cities, and restore the atmosphere as soon as possible. This is the workers' responsibility. The positioning of large cities is general large cities with a population of one million, large cities with a population of 5 million, and international cities with a population of 10 million. Priority will be given to international cities, because lighting, etc., costs the most.
Compared with building a space base, restoring the earth's environment is more important, especially as the construction of the space base has recently entered a stage of elaboration. The two existing Rise aircraft can be deployed in a short time to provide two space reflective sun visors. service.
The first wave of installations is reflective panels, which will be placed around the earth to reflect back the sunlight that does not hit the earth and increase the lighting time on the earth. Because the reflector uses a small amount of photovoltaic cells (for personal use) and a large amount of aluminum foil, supported by a plastic plate with holes, and then uses an aluminum profile as a bracket, the excellent design makes the weight very light, while ensuring good quality. , the average weight per square meter is only 1.5 kilograms.
It's just that these things are still sent to China's space station for assembly before being transported to the designated space location. However, 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 equipped with photovoltaic cells, they are much heavier. Even if it is because Gaoshang Company and China's national construction use a large number of photovoltaic cells to promote the upgrading of the industry, the current photovoltaic cells are still about 5 kilograms per square meter. Of course, it is also possible to use thin-film batteries like those used in satellites, but the cost is too high and it is not universal.
Therefore, two aircraft can transport 0.1 square kilometers of reflective film and 0.03 square kilometers of sun visors to space each time on average. The rest of the tools, materials, personnel, etc., followed the Dream, Explorer or Soar space shuttles to space.
The whole world is fighting for the cause of space, except for those countries that are poor and backward and waiting to die. Everything seems to be prosperous; although mankind has paid a high price for this.
However, God always likes to joke; to be precise, human technology cannot guarantee that there will be no accidents in aerospace. No matter which country it is, there have been countless accidents before the current technology was developed.
And this time, it’s Russia’s turn!
A large number of launch vehicles are used, especially the propellers of launch vehicles that can be recycled; in order to save costs, Russia has even pushed recycling technology to the top of the world. But there is a term for metal: metal fatigue. The core temperature of the launch vehicle is as high as 3,300 degrees or more. Without special materials, the steel will melt. Fortunately, this kind of temperature is quickly discharged from the propeller, and then filled with cold fuel. However, such a harsh working environment has gradually overwhelmed the thruster.
However, in recent years, Russia has used a large number of propulsion rockets to make up for the disadvantage of not having enough space shuttles, and the rocket thrusters must be recycled. Under such conditions, a problem finally occurred today, April 1st!
However, the time when the problem occurred was really - what a coincidence!
When the thrusters were about to break away, one of the thrusters was overwhelmed and exploded. The large amount of liquid hydrogen and oxygen caused an explosion comparable to that of a small nuclear warhead, and exploded more than 200 kilometers above the ground. The explosion directly caused the Russian transport capsule to disintegrate. However, under the influence of inertia and the explosive thrust of the explosion, more than 30% of the debris of the transport capsule was ejected into low-Earth orbit of 300-500 kilometers in space. Tens of thousands of fragments move recklessly here, some faster than 3 kilometers per second, or even seven or eight kilometers; some slower than bullets.
Damn it, 99% of the space bases, satellites, facilities, etc. on the earth are now in low-Earth orbit! When Russia urgently notified the world of this information through public channels, for a moment, the whole world fell silent! ! !
