The wreckage of a Chinese rocket hits Earth and burns up in the atmosphere
US SpaceX rocket debris reaches 3m falling to the ground
Threatens satellites and space stations 10 times the speed of bullets

Satellites that have reached the end of their life orbiting the earth or pieces of rockets launched into space are called space debris.
This space debris is becoming an international headache because it can collide with other satellites or fall to the ground.
The space debris disposal industry is emerging as a new food source for the space industry.

Objects falling to Earth in a line pulling a long tail!
It’s not a shooting star, it’s the remains of a rocket launched by China.
In July, an object that fell from space was found on a farm in Australia.
It turned out to be the wreckage of a US SpaceX rocket, measuring 3m long.
Space debris like this is a danger in outer space too.
Moving more than 10 times faster than a bullet, it collides with a satellite, destroys it, and rushes into the International Space Station, causing the astronauts to evacuate.

As space debris emerges as a global scourge, companies are scrambling to develop related technologies.
A Japanese company developed a space debris collection satellite last year and launched it into space along with a man-made garbage satellite.
After months of flight, the collection satellite has even managed to reunite with the trash satellite.
The aim is to remove real British satellites from Earth orbit by 2026.
The European Space Agency is developing a claw-arm satellite that can capture space debris, drag it down into the atmosphere and burn it up.
It is planned to launch as early as 2025.

The European Space Agency is also developing a satellite that launches nets from space to catch space debris.
Among the space debris orbiting the earth, there are about 36,000 objects with a diameter of more than 10 cm!
Although every country’s access to space is expected to increase further, the size of the space debris removal industry is expected to grow to 18 trillion won in our currency by 2030.
