The UK space sector is a hotbed of innovation, development and collaboration. One of the most pressing challenges facing the industry today is space debris, posing risks to current and future space missions.
Active debris removal (ADR) has emerged as a critical technology in addressing the space debris issue, ensuring the sustainability of space activities. The UK is positioning itself to be at the forefront of these efforts, spearheading projects to develop and implement ADR technologies.
What is space debris?
Space debris refers to defunct human-made objects in space, such as old satellites, spent rocket stages and fragments from disintegration, erosion and collisions. These objects pose significant risks to both current and future space missions.
UK active debris removal initiatives
The UK Space Agency has been proactive in tackling the space debris problem, with nearly £10 million in funding committed so far. This will help develop the key technologies required to locate, inspect, safely dock with and remove space debris. These technologies are the first step to unlocking an emerging market in In-orbit Servicing, Assembly and Manufacturing (ISAM).
Addressing the issue of space debris is crucial
for fostering innovation and attracting
investment in the UK space sector.
ADR mission concepts by two UK companies, Astroscale and ClearSpace, passed their preliminary design reviews in early 2024 and recently commenced the next phase of work. This will develop and derisk the technologies involved, which also have applications for other ISAM activities, such as satellite refuelling and life extension. This phase will be complete by March 2025, after which a mission concept is expected to be selected and funded for launch within the next few years. If successful, it will de-orbit two defunct UK-licenced satellites in one of the world’s first ADR missions, demonstrating UK leadership.
Why addressing space debris matters
Addressing the issue of space debris is crucial for fostering innovation and attracting investment in the UK space sector. By developing and implementing ADR technologies, the UK is positioning itself as a leader in sustainable space practices.
This not only enhances the safety and longevity of space missions but also drives technological advancements and economic growth. Ultimately, these efforts will contribute to a more sustainable future in space, ensuring that space remains a viable and safe environment for future generations.
