Space debris as a research area focuses on the characterization, modeling, monitoring, and mitigation of artificial objects orbiting Earth that are no longer functional, including defunct satellites, spent rocket bodies, and fragmentation products. It encompasses orbital dynamics and environment modeling, collision probability assessment, re-entry prediction, material response during breakup, and the long-term evolution of the debris population. Research addresses sensor technologies and data processing for tracking, space surveillance and tracking (SST) architectures, mitigation and remediation strategies (e.g., post-mission disposal, active debris removal), and the development of technical standards and guidelines to preserve the sustainability and safety of space operations.
