Context
The Indian Space Research Organisation (ISRO) recently released the Indian Space Situational Assessment Report (ISSAR) for 2025. The data highlights a record-breaking 315 successful global space launches that placed 4,651 objects into orbit. With a net annual space object growth of 74.5%, the report underscores the rapidly increasing congestion in outer space and the urgent need for robust space debris management protocols.
UPSC Perspectives
Technological Lens
The exponential rise in orbital deployments emphasizes the critical need for Space Situational Awareness (the practice of tracking space objects and predicting their orbits to avoid collisions). In India, this mandate is spearheaded by the , which compiles the ISSAR annually to evaluate orbital threats. This dedicated facility acts as the central control hub for executing Collision Avoidance Manoeuvres (adjusting a satellite's path to dodge incoming debris) to protect high-value operational assets. To build independent tracking capabilities rather than relying on foreign data, India is aggressively developing , a network of indigenous radars and optical telescopes designed to detect orbital hazards. UPSC candidates should note that as private sector participation increases, self-reliance in space tracking capabilities becomes a crucial sovereign necessity.
Environmental Lens
Outer space is increasingly threatened by the proliferation of space debris, leading to growing fears of the Kessler Syndrome (a theoretical cascading chain reaction where collisions generate more debris, eventually rendering specific orbits completely unusable). While the ISSAR notes that 1,911 objects safely re-entered the Earth's atmosphere in 2025, the staggering net annual growth of 74.5% in orbital objects poses a severe environmental hazard in low Earth orbit. Dead satellites, spent rocket upper stages, and fragmentation debris travel at extreme hyper-velocities, meaning even millimeter-sized flecks can critically damage or destroy active satellites. To mitigate this rapidly escalating threat, India has ambitiously committed to the by 2030. This initiative mandates that all Indian space actors ensure safe post-mission disposal, active debris removal, and sustainable satellite design.
Governance and International Relations Lens
Operating in a congested orbital environment requires robust Space Traffic Management and compliance with global sustainability norms. As mega-constellations of commercial satellites dominate the skies, existing multilateral treaties like the Outer Space Treaty of 1967 are proving inadequate for modern challenges. India actively shapes emerging protocols by adhering to the technical mitigation guidelines of the and participating in (the UN committee governing the peaceful exploration of space). Domestically, the formally integrates debris mitigation and sustainable space operations into the regulatory framework for both ISRO and private sector startups. For Mains, understanding India's transition from merely being a space-faring nation to a responsible global stakeholder and rule-maker in space governance is highly relevant.
