Why space debris is a growing threat: Can a global effort solve it?

As humanity's ambitions for space exploration and satellite deployment grow, so does the problem of space debris. Space debris, or orbital debris, is now a major concern, posing a significant threat to both operating satellites and the safety of future space missions. According to a recent analysis by the European Space Policy Institute (ESPI), global efforts to reduce the spread of space debris are gaining momentum, but much remains to be done.

The growing space debris crisis

Over the past few decades, space missions have resulted in an increase in the amount of debris in Earth's orbit. This includes everything from decommissioned satellites to debris from collisions. Although space debris may not be visible from Earth, its effects are very real. Even tiny fragments can cause catastrophic damage to satellites and spacecraft, given the incredible speed at which they travel.

International response

Global organizations, governments and private companies have begun to take this problem more seriously. ESPI's report highlights various initiatives aimed at addressing the risks of space debris. From the first guidelines of the Inter-Agency Space Debris Coordination Committee (IADC) in 2002 to the European Space Agency's (ESA) Zero Debris Charter in 2023, these efforts are creating a framework for more sustainable space practices. However, the lack of a unified international approach is a stumbling block, as different regions have varying degrees of commitment to combating space debris.

The role of technology and innovation

The latest technologies play a decisive role in this struggle. New methods are being developed to actively remove debris from orbit, including robotic arms and nets that can capture defunct satellites and large debris. In addition, satellite manufacturers adopt design strategies that allow spacecraft to deorbit and burn up in the Earth's atmosphere at the end of their useful lives.

A call for global cooperation

As highlighted in the recent UN Pact for the Future, global cooperation is essential to creating long-term solutions. By setting clear international rules, sharing data, and fostering public-private partnerships, we can prevent space from becoming an impenetrable dumping ground. Without coordinated action, the danger of cascading collisions, often referred to as "Kessler syndrome," could render some orbits unusable, jeopardizing our satellite technologies on Earth.

Conclusion: It's time to act

While the progress made so far is encouraging, the problem of space debris calls for even more decisive action. The growing consensus on sustainable space development offers hope, but without international cooperation, our efforts may fail. As space exploration continues to expand, it's time to act on space debris before it's too late.
