Liao Fan and his crew are driving his Skylark wrecker spacecraft in the seventh group of the wrecker clearance section of the Communications Department of the Outer Space Department of the Earth Space Force, and his team members are carefully traveling through the space orbit thousands of kilometers away from the earth, surrounded by large swaths of space junk that are flying at high speed under the earth's gravity.

These garbage, orbiting the entire earth, look like a thick cloud and mist from afar, gray and obscuring the sight and light source of the earthlings, seriously affecting the light intensity of the earth's surface. When you get closer, you will find that the composition is extremely complex, including the fragments of various satellites launched by the earthlings, the wreckage of the space force fighters, the mummies formed by human bodies in the space environment, and the corpses of various types of Zerg creatures left in space, the enemies of mankind.

This is the result of the war between humans and the Zerg that lasted for more than three years, the war created tens of millions of tons of cosmic garbage in the cosmic space between the earth and the moon, some of which were too fast, broke away from the earth's gravity early and flew farther into space, and some were too slow, and soon fell into the earth and became part of the earth's atmosphere, while a small part of it maintained a relatively constant speed and was captured by the earth's gravity and became the earth's satellite garbage.

As the amount of space debris continues to increase, the probability of collision between these debris also increases, resulting in more debris, and when the amount of debris accumulates to a certain extent, it forms the current magnificent and powerful garbage cloud, which rotates around the earth at high speed in a ribbon-like ring along the Earth's orbit, with an average speed of tens of thousands of kilometers per hour and a width of thousands of kilometers, just like the dream-like and beautiful rings of Saturn, which mankind once envied, but on a much smaller scale. It is called the star skirt by the earthlings with a very silk temperament, which means the skirt of the mother earth.

This kind of cosmic wonder is full of charm, but when it really descends on the earth, the earth knows what it means behind this beauty, the high-speed flying garbage cloud is impermeable, the gap is very small, and the road that originally earthlings lifted off by rockets is almost a dead zone, if the earthlings do not have corresponding measures to deal with it, in the process of rocket liftoff, each of these high-speed flying micro-satellite garbage is enough to become a deadly killer, at a high speed of more than 30,000 kilometers per hourOnce it hits a human flying object in operation, it will inevitably be a situation where the earthlings and ships will be destroyed immediately.

In fact, it has already caused great harm to the earth -- before the war, according to statistics, the earthlings launched more than 6,000 satellites in space orbit, some for military affairs, some for weather, and some for data communication, but now there is no doubt that all of these have been completely destroyed under the attack of the garbage cloud and have become new cosmic garbage. As a result, the modern satellite communication and observation system covering the whole world, which has been built by the earthlings for half a century, has disappeared.

This also forced the earth to establish a new global network communication system in the atmosphere that completely got rid of the dependence on satellites, of course, this is a rather expensive investment, and the cost of maintaining a global communication system in the atmosphere is naturally much higher than that of geosynchronous satellites, which is more than 100 times higher than that of the former orbital satellites.

This is one of the important consequences of the Zerg War's great impact on humanity.

In order to reopen the way for human beings to fly to space and clear a clear vision for the earth, the earthlings must find a way to deal with these space junks as soon as possible.

From the current technology, there are two main ones, the first is to use various technologies to improve the strength of the shell of the human space object itself: the latest space battleship of the earthlings, the cross-star battleship Titan, is built based on this line of thought, and the shell made of his new materials is extremely strong, enough to withstand the high-speed impact of this tiny space junk, of course, it can be rampaging like an icebreaker in the Arctic Ocean in the star skirt. It's just that the cost of this method is too high, and it is simply impossible for ordinary flying objects, except for warships.

And another way of thinking is to clear the obstacles, just like the sanitation workers in the earth's human political axe, regularly clean up the garbage on the road, and gradually clean up these space junk, in the long run, this method is also bound to be implemented, the so-called star skirt, after all, is not what the earthlings want, every time it is delayed in the earth's orbit, it will cause unspeakable damage to the development of the earthlings and the counteroffensive plan.

Liao Fan is a member of the wrecker team of Mother Earth, and he and his team members have to fly into space twice a month in a special wrecker to carry out programmed wrecker tasks.

In his group, there are two wreckers, and another 120 Li Mifan piloted by intelligent programs, among which Li Mifan, as the name suggests, is a spacecraft invented by a scientist named Li Mi and powered by solar sails. It has a set of automatic obstacle removal procedures, that is, with its own solar sail power, it constantly picks up space junk in space and adsorbs it on its own body, until finally, the weight of its own adsorption is too large, causing its own gravity to be too large, and it is dragged into the atmosphere by the earth's gravity and crashes.

The other two wreckers are another method of wrecker.

The two wreckers are like fishermen in the sea of space, from both sides of the space to open an unprecedented scale of large nets, enough to cover hundreds of square kilometers, this large net is made of the latest nanomaterials, the total weight of each square kilometer of materials is less than two kilograms, but the strength is extremely high, enough to withstand the impact of space junk hundreds of tons and thousands of tons. With the vigorous power of the wrecker itself, it drags this large net through the star skirt, captures space junk, and then pulls it into the atmosphere and crashes, which can process thousands of tons of garbage and waste at a time, with extremely high efficiency.

Through these two methods, Liao Fan and his team were able to clean up more than 10,000 tons of material in the star skirt every time they went to work, twice a month, and 24 times a year, they were able to clean up more than 200,000 tons of space junk.

The entire wrecker removal program of the Space Force, including 50 teams like Liao Fan, each of whom is currently the top astronaut on Earth, has been performing this work day and night since 2018.

Reopening the vision of the earth, opening up the road to space for mankind, Liao Fan and his companions have paid a lot for the future strategic counteroffensive of the Space Force.
