PIB TrackerThousands of internet satellites, and the debris nobody can dodge
ISRO told Parliament it is seized of Low Earth Orbit constellation proliferation, warning that small untrackable debris can neither be avoided nor shielded against — and pointing to its Debris Free Space Mission and Active Debris Removal.
What happened
- ISRO is seized of the proliferation of Low Earth Orbit satellite constellations causing space debris.
- Internet constellations typically involve a few thousand satellites, raising collision risk in their orbital shells.
- Small untrackable debris can neither be avoided nor adequately shielded against.
- ISRO's Debris Free Space Mission covers Active Debris Removal and other measures.
- ISRO has been a member of the IADC since 1996; the Committee was formed in 1993.
For Prelims
- LEO: Low Earth Orbit, roughly up to 2,000 km — where internet constellations and most Earth observation satellites operate.
- IADC: the Inter-Agency Space Debris Coordination Committee, formed 1993; ISRO a member since 1996.
- UN-COPUOS: the Committee on the Peaceful Uses of Outer Space, which handles debris mitigation and long-term sustainability.
- ADR: Active Debris Removal — capturing and de-orbiting existing debris, as against merely preventing new debris.
- Kessler syndrome: the cascade in which collisions generate debris that causes further collisions.
- Indian Space Policy 2023: mandates internationally recognised guidelines for end-of-life disposal of satellites.
- ISRO's own systems: IS4OM (System for Safe and Sustainable Operations Management) and Project NETRA for space situational awareness.
- Outer Space Treaty, 1967: the base instrument; a launching State retains liability for its objects.
For UPSC: The best space-governance card of the month. Use it for space debris and the Kessler cascade, the global commons problem in orbit, liability under the Outer Space Treaty, and why private mega-constellations are a regulatory question rather than only a technical one.
What it is NOT: There is no binding international law requiring debris removal — IADC and COPUOS guidelines are voluntary, and the reply describes India's capability and engagement, not an enforceable regime.
For Mains
Syllabus: GS3.13 · GS2.20 · Linkage L2
Anchor
Orbit is a commons with no traffic law — and the traffic has grown into the thousands.
Substantiation (data)
Constellations of a few thousand satellites each, with failed satellites unable to manoeuvre and small untrackable debris that cannot be dodged or shielded against.
Exemplification
ISRO's Debris Free Space Mission and Active Debris Removal sit alongside membership of the IADC since 1996 and representation at UN-COPUOS.
Problematisation
Debris guidelines are voluntary while the commercial incentive to launch is immediate — a single fragmentation event in a populated shell can foreclose an orbit for everyone.
Way-forward
Push for binding end-of-life disposal obligations at COPUOS, build indigenous space situational awareness, and price debris risk into launch authorisation.
Position
A country that plans to keep assets in orbit for fifty years has a direct interest in orbital traffic rules today.
Deploys into: Space technology + international institutions (GS3.13, GS2.20) · space debris and the Kessler cascade, the orbital commons, and liability under the Outer Space Treaty.
