Orbital debris is emerging as a critical global commons challenge. Discuss India's regulatory response in this regard.

Outer space is a global commons — usable by all, owned by none. With several thousand active satellites crowding low-earth orbit and mega-constellations planned, defunct stages and fragments now threaten a cascading collision risk, making debris governance as much a regulatory question as a technological one. India has responded by moving from mission-level practice to a formal authorisation regime.

Why debris is a commons challenge

• Non-excludable, congestible orbits: every operator gains from launching, while collision risk is borne collectively — a classic tragedy of the commons.
• Uncontrolled re-entry endangers life and property on the ground and in air corridors.
• International norms remain soft law — the UN COPUOS Space Debris Mitigation Guidelines (2007) are voluntary, leaving enforcement to national regulators [4].

India's regulatory response

• Indian Space Policy, 2023 created the enabling framework, making IN-SPACe the single-window authorising body for space activities, including planned re-entry of space objects [1].
• IN-SPACe re-entry guidelines (2026) — India's first — require prior authorisation for any planned re-entry by an Indian entity, whether within or outside Indian territory; foreign entities re-entering within Indian territory are equally covered [2].
• Safety benchmark: casualty probability must be below 1 in 10,000, aligning India with NASA/ESA practice rather than inventing a lower standard [2].
• Risk allocation: the Government assumes no liability; operators bear the risk at their own cost and must carry adequate insurance, with advance notification to aviation and maritime authorities [2].
• Mission-level commitment: the Debris-Free Space Missions target of 2030, implemented through ISRO's IS4OM, mandates controlled de-orbiting and post-mission disposal [3].

Together, these measures convert voluntary global norms into enforceable domestic obligations, letting India expand private participation without externalising risk onto the commons. The remaining gap is statutory — a comprehensive Space Activities Act would give these guidelines legislative backing and clearer liability rules. Codifying them would strengthen India's standing as a responsible spacefaring power committed to sustainable use of outer space.
