The rapid increase in satellites and spacecraft has led to a critical rise in orbital debris, posing severe risks to active missions and long-term sustainability in space. Defunct satellites, spent rocket stages, and collision fragments threaten to trigger cascading collisions, making active debris mitigation an urgent priority. This project investigates a space-based laser debris mitigation system as a proactive solution to reduce orbital debris hazards.

The proposed system employs high-powered lasers mounted on space-based platforms equipped with precision pointing, advanced optics, and real-time tracking technologies. Unlike ground-based systems, space deployment eliminates atmospheric interference and enables direct access to debris across multiple orbital regimes, including LEO, MEO, and GEO. The operational principle involves directing focused laser pulses at debris surfaces to induce localized ablation, generating a recoil force that alters the object’s velocity and trajectory. This controlled perturbation enables orbital decay or relocation to less congested regions.

Integrated debris tracking, adaptive control algorithms, and optimized laser parameters ensure effective engagement across a wide range of debris sizes and materials. The system’s versatility allows mitigation of both large trackable objects and smaller high-risk fragments.

Key challenges include high power demand, energy storage, thermal management, system integration, and international regulatory concerns related to the dual-use nature of directed-energy technologies. Future work will focus on improving laser efficiency, compact power systems, advanced tracking algorithms, and simulation-based validation, alongside international collaboration.

Overall, space-based laser debris mitigation offers a scalable and effective approach to enhancing orbital safety and ensuring the long-term sustainability of space operations.
