Active Debris Removal (ADR)

Active Debris Removal (ADR) refers to the techniques and technologies used to remove space debris—pieces of defunct satellites, spent rocket stages, and fragments from collisions—orbiting Earth. As the number of these objects increases, they pose risks to operational satellites and spacecraft. ADR methods may involve capturing debris with nets, harpoons, or robotic arms, and then deorbiting it safely to burn up in the atmosphere. The goal is to ensure safer and sustainable use of space, protecting valuable satellite infrastructure and maintaining the long-term viability of space activities.
