Space organizations are increasingly prioritizing the reduction and cleanup of space debris to ensure the sustainability and safety of space operations. The proliferation of space debris poses significant risks to satellites, space stations, and future space missions. Several strategies and technologies are being developed and implemented to address this challenge.

One approach is the improvement of satellite design and end-of-life disposal strategies. Satellites are now being designed with de-orbiting mechanisms that allow them to be safely removed from orbit once their mission is complete. This includes using propulsion systems to direct them toward Earth’s atmosphere, where they burn up upon re-entry, or into graveyard orbits far from operational spacecraft.

Another strategy involves active debris removal (ADR) technologies. These include robotic arms, nets, harpoons, and tether systems designed to capture and de-orbit larger pieces of space debris. For example, the European Space Agency (ESA) is working on the ClearSpace-1 mission, which aims to capture and remove a piece of debris using a robotic arm. Similarly, Japan’s Aerospace Exploration Agency (JAXA) is experimenting with tether systems to slow down and de-orbit debris.

In addition to these methods, space situational awareness (SSA) is crucial. Advanced tracking and monitoring systems are being developed to accurately predict the trajectories of space debris and avoid potential collisions. These systems help in creating collision avoidance maneuvers, protecting active satellites and space stations.

International collaboration and policy development are also vital components of the effort to manage space debris. The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and other international bodies are working on guidelines and agreements to ensure responsible behavior in space. This includes measures such as limiting the creation of new debris and enforcing compliance with space debris mitigation standards.

Overall, the combination of improved satellite design, active debris removal technologies, advanced tracking systems, and international cooperation forms a comprehensive approach to mitigating the risks posed by space debris and ensuring the long-term sustainability of space activities.
