The growing threat to satellites from space debris

The space debris problem has worsened in recent years, endangering satellites in the international space station. The increasing number of objects in Earth’s orbit poses a significant risk to the space environment and threatens space sustainability. This exponential increase in space debris heightens the likelihood of collisions occurring, leading to higher costs and prompting recommendations for recycling from the European Space Agency (ESA). Even small fragments of space debris can cause significant damage due to the high velocities at which they travel in orbit. Recycling and cost are important considerations when it comes to managing space debris. To address this issue, the European Space Agency (ESA) has provided recommendations for effective management.

Satellites play a crucial role in various aspects of our lives, including communication through the international space station, weather forecasting, navigation with the space surveillance network, and scientific research in the space sector. However, the importance of the European Space Agency (ESA) also makes them vulnerable to the threats posed by space debris, which can significantly impact their cost. With the increasing number of active satellites in orbit and the regular launch of new ones, it is crucial to prioritize space debris management and implement space industry debris mitigation recommendations to ensure space sustainability.

One of the key challenges faced by the space sector is managing the ever-increasing amount of orbital debris. The term “space debris” refers to defunct satellites, spent rocket stages, and other fragments that are no longer operational but remain in Earth’s orbit. These large debris objects pose a significant risk in the space industry, as they can collide with active satellites or even with each other, creating a cascade effect known as the Kessler Syndrome. To address this issue, space debris management and debris mitigation recommendations have been put forth by organizations like Axiom Space.

To effectively manage space debris, it is crucial to have a comprehensive understanding of the orbital environment and track all objects within it. Implementing space industry debris mitigation recommendations can help address the threat posed by large debris.

By tracking these objects’ trajectories and providing timely information on potential collisions, the SSN enables satellite operators to make informed decisions about maneuvering their spacecraft out of harm’s way.

In addition to tracking large pieces of debris in the space industry, attention must also be given to smaller fragments that are more difficult to detect but still pose a significant threat. Low Earth Orbit (LEO), in the space industry where most operational satellites reside, is particularly crowded with both large and small debris. Small pieces of space industry debris can travel at high speeds relative to satellites and cause severe damage upon impact due to their kinetic energy. It is important for the space industry to implement debris mitigation recommendations to prevent such incidents.

Addressing this challenge requires collaborative efforts from the international space community. Governments, space agencies, and private companies must work together to develop strategies for debris mitigation and removal. This includes implementing measures in the space industry such as designing satellites with built-in disposal capabilities or deorbiting them at the end of their operational lives.

Another approach being explored is active debris removal (ADR), which involves capturing and removing large debris objects from orbit. Various ADR technologies are being developed, including robotic arms, nets, and harpoons. These technologies aim to capture defunct satellites or spent rocket stages and safely bring them back into Earth’s atmosphere to burn up upon reentry.

Furthermore, efforts are underway to promote responsible space practices among satellite operators. This involves minimizing the creation of new debris through improved spacecraft design and mission planning. For example, satellites can be designed with deployable structures that reduce their size during launch and then expand once in orbit, reducing the risk of collision with other objects.
