Space exploration has opened fascinating horizons, but it has also brought new challenges, among which is the management of space debris. Since the launch of the first satellite in 1957, over 20,000 objects have been abandoned in low Earth orbit, creating a true space pollution issue. These debris, such as pieces of defunct satellites or fragments from explosions, represent a growing risk not only for ongoing space missions but also for orbital infrastructure. In response to this issue, a multitude of initiatives are emerging, aiming to identify sustainable solutions to minimize the impact of this pollution while ensuring the safety of space operations.
The issue of space debris has become a major concern in the field of astronomy and space exploration. With the increasing number of satellites and spacecraft launched into space over several decades, space pollution is rising exponentially. This article examines the challenges posed by this situation as well as the various proposed solutions for managing and reducing debris in orbit.
The challenges of space debris
Space debris, which includes remnants of satellites, rocket stages, and other objects, threatens the safety of current and future missions. Currently, over 20,000 objects are being tracked in low Earth orbit, posing a potential risk to spacecraft. Each collision, even at low speeds, can lead to additional debris, exacerbating the already concerning problem.
One of the most concerning aspects is that explosions in orbit are the primary contributor to space pollution. These incidents often occur due to leftover fuel or materials inside spacecraft, leading to the fragmentation of objects and an increase in debris. The consequence is a space environment that has become increasingly dangerous for any future mission.
Solutions for space debris management
In the face of this crisis, several approaches have been considered to mitigate the effects of space debris. One solution involves modifying the orbits of debris so that they re-enter the atmosphere and disintegrate. This strategy requires careful planning and the use of advanced technologies to ensure that the debris do not collide with other objects in orbit.
Another approach concerns the regulation of new satellite launches. By adhering to the “25-year rule,” which stipulates that any satellite at the end of its life must be deorbited within 25 years of its last mission, the amount of new debris generated can be limited. This also requires international cooperation and the establishment of strict policies at the level of space agencies.
Monitoring technologies and innovations
To effectively address this problem, the latest advancements in artificial intelligence and tracking technologies are crucial. These tools allow for the monitoring of objects in orbit and the anticipation of potential collisions. Detection and monitoring projects are subject to intensive research to better manage existing and unforeseen debris.
New Space initiatives are also focused on methods to clean up space, developing technologies capable of proactively removing debris or limiting the creation of new waste. This includes innovative concepts such as space nets or devices that can capture and deorbit debris.
International collaboration and the need for action
The management of space debris cannot be treated in isolation. It requires international cooperation, as space is a shared domain. Nations must collaborate to establish common standards and devise strategies for the prevention and removal of debris. This will involve discussions on the regulation of space missions and the sharing of responsibilities in cleaning up space.
The challenge of space debris is immense, but with collective determination and a willingness to innovate, it is possible to protect our space environment and ensure the sustainability of future explorations. Solutions exist; it is time to take action.

The issue of space debris has become a major topic in the field of astronomy and space exploration. As the use of space continues to grow rapidly with the launch of new satellites and missions, managing this debris is crucial to ensure the safety of missions and preserve the space environment. This article explores the challenges related to space debris and examines current and future solutions for effectively managing them.
The challenges of space debris
Space debris represents an increasingly significant risk to operational satellites and manned missions. Currently, over 20,000 objects pollute low Earth orbit, a legacy of numerous space missions since 1957. Among the main causes, explosions in orbit and collisions between objects significantly contribute to the increase of this pollution.
The safety of spacecraft is jeopardized by this debris, which could lead to catastrophic accidents. Additionally, the growth in the number of satellites, especially within New Space projects, inevitably increases the risk of collision, underscoring the urgency of devising debris management strategies.
Management solutions
To address this challenge, several innovative solutions are emerging. For example, modifying the orbits of debris is seen as an effective method for bringing them back into the Earth’s atmosphere. This would allow for controlled disintegration, thereby reducing the amount of debris in orbit.
Another approach is to adhere to the 25-year rule, which stipulates that satellites at the end of their life must be removed from orbit within 25 years. By integrating advanced tracking technologies and artificial intelligence, it becomes possible to monitor and predict the movement of these debris, thus facilitating safe planning for space missions.
International initiatives
At the international level, several organizations are collaborating to develop prevention policies and standards. The development of a map of space debris allows for visualization of their distribution and movement, thereby contributing to informed decision-making. Additionally, collaborative projects between space agencies, such as CNES and ESA, strengthen the collective commitment to managing debris.

This article examines the challenges associated with the management of space debris as well as the solutions considered to ensure a safe and sustainable space.
The challenges related to space debris
The multiplication of debris in orbit presents considerable challenges. First, these objects fly above operational satellites and can lead to catastrophic collisions. Explosions of spacecraft in orbit are one of the main sources of debris accumulation, releasing thousands of pieces that later become threatening projectiles.
Moreover, the accumulation of debris makes it difficult to launch new missions, as each launch must take into account the need to avoid collisions. Many satellites must alter their trajectories to evade debris, which increases operational costs and can reduce mission lifespans. Effective debris management is therefore essential to preserve the safety and viability of space activities.
Solutions to reduce debris in space
Regulation of satellites
One of the first steps to minimize debris production is to adhere to strict rules regarding the end of life of satellites. The 25-year rule recommends that all low Earth orbit satellites should return to the Earth’s atmosphere within 25 years of deactivation. This measure aims to reduce the number of new debris and facilitate a safe return of obsolete objects.
Tracking and elimination technologies
Advanced debris tracking technologies have emerged, allowing precise and continuous monitoring of orbital space. Thanks to artificial intelligence and sophisticated detection systems, it is now possible to track over 20,000 objects in orbit. A detailed understanding of the distribution and movement of these debris allows for the prediction of collision risks and adjustments of satellite trajectories accordingly.
Furthermore, several projects have been proposed to actively eliminate debris. Space missions could be launched to capture and deorbit cumbersome objects. Among the innovative ideas are the use of nets, harpoons, or even lasers to redirect debris toward a controlled reentry into the atmosphere.
International collaboration
The management of space debris is a global issue requiring international cooperation. Countries must work together to establish uniform regulations and share data regarding space traffic. It is crucial to involve both governmental space agencies and private companies in this effort to ensure responsible management of space.
As the number of objects in orbit continues to grow, it is imperative to take concrete actions to manage space debris and maintain a healthy orbital environment. The application of effective regulations, the development of new technologies, and international collaboration are key elements in the fight against space pollution.
