As we explore and use outer space to advance science and technology, we are faced with a growing and worrying problem: the space junk. Millions of fragments of abandoned objects and debris orbit the Earth, posing a significant threat to space missions and satellite infrastructure. In this article we will delve into the problem of space junk, its origin, impact and the innovative solutions that are being developed to address this worrying situation. Join us on this journey through space and find out how we deal with this silent threat.
Origin and accumulation of space junk
Space junk originates from a combination of discarded objects, abandoned rocket stages, and collisions between satellites and fragments. As humans have explored and used space for decades, we have left a trail of debris in orbit around Earth. These fragments, which range from small particles to large disused satellites, accumulate and pose a real risk to space missions and active satellites.
Dangers and consequences of space junk
Space junk poses multiple dangers and consequences for both space missions and life on Earth. As the amount of space junk increases, so does the risk of in-orbit collisions. These collisions can generate more fragments and cause a chain reaction known as the Kessler effect, in which fragments collide with each other, generating even more space junk and making safe access to space more difficult. In addition, space junk poses a threat to active satellites, which are essential for communications, Earth observation, navigation, and scientific research.

Solutions and mitigation
To tackle the problem of space junk, scientists and space agencies are developing innovative solutions. These solutions include active removal methods for space junk, such as the use of net-equipped satellites or robotic arms to capture and remove fragments, as well as deorbiting technologies that allow satellites to disintegrate in Earth’s atmosphere at the end of their useful lives. . In addition, measures are being implemented to reduce the generation of space junk, such as the design of satellites with components that disintegrate in a controlled manner or the responsible launch of rockets.
International cooperation and regulations
Given the global nature of the space junk problem, international cooperation and regulation are essential. Organizations such as the United Nations Outer Space Organization (UNOOSA) and the European Space Agency (ESA) are working together to promote the adoption of safe and sustainable practices in space. In addition, international agreements are being discussed to establish clear rules and responsibilities in relation to space junk.
The space junk problem thus represents a real and growing threat to our activities in space and to the satellite infrastructure that has become so crucial to our daily lives. However, through technological innovation, international cooperation and the adoption of effective regulations, we can address this worrying situation. With solutions like active space junk removal and controlled satellite deorbiting, we can safeguard our access to space and ensure a safe and sustainable orbital environment for future generations.
