Worker Bee-1 moves nimbly through the space junk heap, and the maneuvering vent can ensure its ability to maneuver and prevent those large pieces of space junk from hitting it.

Of course, it's also because it's not as fast as the space junk is so fast that it looks like a fluttering balloon, and it looks like a stroll rather than a fierce racing race.

However, some small things still fly fast, and they are too small and too fast to be monitored as well as large pieces of space junk, and when they are detected, it is too late to dodge.

So in this process, the audience can always hear a few "ding-ding-clang" crashes every once in a while.

They were terrified when they listened!

People's space stations, satellites, and space vehicles are all far away from those space junks, but the Worker Bee 1 engineering spacecraft can't, and its mission is to drill into the space junk heap.

Because of this, it is equipped with armor.

But because they are protected by armor, they can see such a scene.

Many people say what's wrong with the current space junk, but people have never seen it with their own eyes, and today they are seeing it.

For example, now, a wrench "Ding Lingdangchang" hit the shell of Worker Bee 1, and then floated in front of the camera.

Audience: "......"

All this garbage in space has a story, not just simple and crude rocket wreckage and scrapped satellites.

During a spacewalk to the International Space Station, an astronaut received an order to repair the station's exterior facilities.

So the astronaut grabbed the repair kit, put on his extravehicular spacesuit, walked through the airtight chamber, and began his spacewalk.

His task was simply to tighten some of the loose screws on the station's casing again, after all, these loose screws were a potential danger for the entire crew.

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

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

Fortunately, the astronauts were professionally trained, and after hours of intense repair work, the astronaut was relieved and took the wrench off the last screw.

Then the unfortunate thing happened, his sudden relaxation gave the Earth an extra "satellite".

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

This wrench becomes space junk.

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

"Fortunately" it is not alone, because there are still Merriken astronaut gloves that have been floating for more than 20 years, as well as some bolts, washers and a pencil that flew out of the decompression module of the "Salyut 7" space station, as well as the "unmartial arts" of early astronauts, the household garbage thrown from the space station or manned module, and so on.

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

Most of the space junk is discarded spacecraft that are left in orbit and float in space indefinitely when a spaceship or part of a spaceship is no longer functional.

After all, the cost of retrieving these things is high, so they are left in space to orbit the Earth until they fall to the ground or collide with other space junk.

There is also the upper stage of the launch vehicle, when the launch vehicle is launched, it usually needs multiple rockets to propel to ascend into space, and these rockets are phased out, and the last stage is called the upper stage, because they are installed near the top position, usually burning very late.

The first or second stage rockets that ignite first stage will stall before entering orbit and will quickly fall back to the ground after separation, while the last ignited upper stage rocket can carry the load into orbit all the way and then orbit the earth.

When the loads are finally separated, they become useless space junk, which is the largest of the bunch.

In addition, there is rocket solid fuel and liquid fuel, and after launch, some of the remaining fuel will drift into a container or leak out.

This makes the collision between the containers a huge danger, after all, it is the fuel that mixes and produces a huge amount of energy to send the rocket into orbit, but that is when there is no supervision, and now that there is no supervision, everything is in a state of chaos, and the chance of them exploding is greatly increased.

Once it explodes, more space junk is generated.

And once it explodes, the situation is even more uncontrollable.

Shortly after the Ariane rocket entered orbit, it exploded and became 564 pieces of 10 centimeters in size and 2,300 pieces of small debris.

The key is an explosion, and these fragments will be sputtered in either direction.

Subsequently, the wreckage of this rocket caused the two communication satellites of the Sakura Country to "die"!

Later, scientists also realized this problem and will 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, it will be frozen at low temperatures, scattered in orbit like steel balls, not much different from the wrench that orbits the earth at high speed at 17,000 kilometers per hour.

Or even worse.

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

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

Aging or collision with other tiny particles often peel off small particles of paint from spacecraft, which then produce this space junk, which is estimated to contain millions of tiny paint chips floating in orbit around the Earth.

All of this is a threat!

It is a threat to the space equipment in operation!

It is also a threat to astronauts who go into space!

Originally, countries had no choice, and they could clean it up, but the cost was too high, so they didn't think much about it.

However, for the threat in orbit, everyone is also concerned, if the orbit is really blocked, then it will be difficult for human beings to get out of the earth, so after the development of science and technology a lot, they will start to think of a way.

It's basically about cleaning up garbage and defending garbage.

Cleaning up garbage is to reduce the amount of garbage, and to get space junk into the atmosphere and burn up through various methods.

Defending against garbage is to stack armor, stack the thickest armor, and it's okay for the spacecraft to be hit by space junk.

It's just that after the launch into orbit, their work efficiency is not very good, or they have not really carried out yet, and only a plan has been made.

Today, Worker Bee 1 is here, and they have made a two-in-one, that is, to reduce the amount of space junk and stack armor.

And according to the plan, the way people reduce the garbage in the sky is not rough at all, but full of technical sense.

"Sure enough, with technology, you can do whatever you want."

"I also think so, if the technology is high, the previous ideas and plans of all parties can be easily realized."

"There is no easy way to achieve it, and the leaders must have made it after a long period of research, and it is the sweat of scientists, engineers and technicians."
