The worker bee one moves flexibly in the space garbage dump, and its mobile spout can ensure its maneuverability and prevent the large pieces of space garbage from hitting it.

Of course, it is also not fast relative to the space junk, so that the space junk looks like a floating balloon, and it looks like a stroll in the courtyard, not like a fierce racing competition.

However, some small things still fly fast, and they are too small or too fast to monitor as well as large pieces of space junk, and there is no time to avoid them when they are detected.

So in this process, the audience can always hear several "ding-ding-dong" crashing sounds at intervals.

They were terrified to listen!

Other people's space stations, satellites, and space vehicles are all hiding far away from the space junk, but the Worker Bee-1 engineering spacecraft cannot work. Its mission is to drill into the space junk pile.

Because of this, it was equipped with armor.

But also because it is protected by armor, so they can see such a scene.

Many people say what happened to the space junk now, but people have never seen it with their own eyes. They have seen it today.

For example, now, a wrench "Ding Ling Dang Cang" hits the shell of Worker Bee 1, and then floated past the camera.

Audiences:"……"

The junk in space has stories, not just simple and rude rocket wreckage and scrapped satellites.

During a spacewalk on the International Space Station, an astronaut received an order to repair the external facilities of the space station.

So the astronaut took the repair tools, put on his extravehicular spacesuit, passed through the airtight capsule, and then began his spacewalk.

His task is very simple. It is to tighten some loose screws on the outer shell of the space station again. After all, these loose screws are a potential hazard for the crew.

Of course, this task is simple, but it is not at all simple.

The gloves of the extravehicular spacesuit are too thick and it is inconvenient to hold the tools. In addition, the weightless environment is also inconvenient to move, and it is too floating, so that simple screwing work is difficult.

Fortunately, the astronauts were all professionally trained. After several hours of intense repair work, the work was completed. The astronaut also breathed a sigh of relief, and then took the wrench off the last screw.

Then unfortunate things happened. His sudden relaxation gave the earth an extra "satellite".

Since he didn't hold the wrench tightly, the wrench slipped out of his hand. He subconsciously reached out to grab it. Not only did he not catch it, he pushed the wrench one further and pushed it into space.

This wrench becomes space junk.

And began to orbit the earth at a high speed of 17,000 kilometers per hour.

"Fortunately" it is not alone, because there are still Meriken astronaut gloves that have been floating for more than 20 years in space, as well as some bolts, washers, and a few flying out of the decompression chamber of the "Salute 7" space station. A pencil, as well as the early astronauts "do not speak martial arts", the domestic garbage thrown from the space station or the manned cabin, and so on.

These are not the main space junk. Compared with the main space junk, they are only the tip of the iceberg, or the tip of the iceberg on the water.

Most of the space junk is abandoned space vehicles. When the spacecraft or part of the spacecraft is no longer in operation, they will be left in orbit, floating in the universe indefinitely.

After all, the cost of retrieving these things is very high, so they are left in space and rotate around the earth until they fall on the ground or collide with other space junk.

There is also the upper stage of the launch vehicle. When a launch vehicle is launched, it usually requires multiple rockets to move up into space. These rockets are stalled in stages. The last stage is called the upper stage because they are Installed close to the top, it usually burns very late.

The first-stage or second-stage rockets that are ignited first are turned off before entering orbit. After separation, they will quickly fall back to the ground, and the last-ignited upper-stage rocket can always carry the load into orbit, and then orbit the ground.

When the final load is also separated, they will become useless space junk, and these are still the largest kind of space junk.

In addition, there are rocket solid fuel and liquid fuel. After launch, some of the remaining fuel will float into a container or leak out at will.

This makes the collision between the containers bring great danger. After all, it is the huge energy generated after the fuel is mixed to send the rocket to the space orbit, but that is under the supervision of someone, and no one is supervising it now. Everything has entered a state of chaos, and their explosion probability has greatly increased.

Once exploded, more space junk will be produced.

Once it explodes, the situation becomes even more uncontrollable.

At the beginning, the "Ariane" rocket exploded shortly after it entered orbit, turning into 564 pieces of 10 cm in size and 2,300 pieces of small fragments.

The key is to explode, these fragments will splash in any direction.

Subsequently, the wreckage of this rocket killed the two communications satellites of the cherry blossom country!

Later, the scientists also realized this problem and would actively release the remaining fuel, so that the risk of explosion is reduced.

But another problem arises, that is, the released fuel will still be in orbit. They will be frozen at low temperature and scattered like steel balls in the orbit. It is the same as the one that orbits the earth at a high speed of 17,000 kilometers per hour. The wrench is not much different.

Even worse.

Because there is only one wrench, but there is a large piece of "steel ball".

There are also some incredibly dangerous space junk, which is the paint on the spacecraft, or tiny paint flakes or particles.

Aging or collisions with other tiny particles usually scrape off the small paint particles from the spacecraft, and then this space junk is produced. According to estimates, there are millions of small paint fragments lurking in space, just in orbit around the earth. Floating.

All of this is a threat!

It is a threat to the running space equipment!

It is also a threat to astronauts entering space!

In the past, countries had no choice. They could clean up or clean up, but the cost was too high, so they didn't think about it.

However, everyone is also concerned about the threats on the orbit. If the orbit is really blocked, it will be difficult for human beings to get out of the earth. So after a lot of technological development, start to think of ways.

Roughly cleaning up garbage and defending garbage.

Cleaning up rubbish is to reduce the amount of rubbish, and let the space junk enter the atmosphere and burn it through various methods.

The defense against junk is the stack of armor, the thickest stack of armor makes it okay for the spacecraft to be hit by space junk.

It's just that after launching into orbit, their work efficiency is not very good, or they have not really proceeded, only a plan has been proposed.

Today, Worker Bee 1 is here, and they have implemented a two-in-one approach, that is, reducing the amount of space junk and stacking armor.

And according to the plan, the method of reducing sky trash is not rude at all, but full of technical sense.

"Sure enough, if you have technology, you can do whatever you want."

"I also feel that if the technology is high, all the previous ideas and plans can be easily realized."

"Nothing is easy to achieve. The pioneers must have been developed after a long period of research. They are all the sweat of scientists, engineers and technicians."
