Space junk has been a problem since the beginning of space exploration. The first object to be considered space junk was Vanguard 1, an American satellite launched in 1958. Although it stopped communicating with NASA in 1964, its aluminum body continues to orbit the Earth and is officially the first space debris created by humans.

Space junk is defined as any man-made object that has been put into orbit and no longer serves a useful purpose. This includes everything from decommissioned satellites and rocket debris to tools lost by astronauts. It is estimated that there are millions of pieces of space junk orbiting Earth, from small pieces of metal to entire satellites.

Why is space junk so dangerous?

Space junk poses a danger to space missions and to life on Earth. Some of the risks posed include:

Collisions: Space debris moves at extremely high speeds, meaning that even a small fragment can cause serious damage to operational satellites or spacecraft.

Risk to human life: Although most space debris is in orbits far from Earth, some fragments can re-enter the atmosphere and, if they do not disintegrate completely, fall into inhabited areas.

Interference with astronomical observations: The accumulation of space debris makes it difficult to observe space and can interfere with communications.

Is it possible to clean up orbital space?

Orbital space cleaning is a complex challenge, but various technologies are being developed to address this problem. Some of the solutions being explored include:

Nets and robotic arms: Satellites equipped with nets or robotic arms are being designed to capture space debris and remove it from orbit.

Lasers: Laser systems are being investigated to disintegrate small fragments of space debris.

"Kamikaze" satellites: Satellites are being proposed that self-destruct at the end of their mission, thus avoiding becoming space debris.

What is being done about it?

Various space organizations and agencies, such as NASA and ESA, are working on developing technologies and strategies to combat space debris. International regulations are also being established to prevent the generation of more debris in space.

Space debris is a serious problem that requires urgent and internationally coordinated solutions. If effective measures are not taken, the accumulation of debris in space could hamper future space missions, endanger human life and pollute the space environment. However, thanks to research and development of new technologies, there is hope that we can clean up orbital space and ensure a sustainable future for space exploration.
