Space debris and India's Debris Free Space Mission goal for 2030
Why in news: On 5 November 2026, the Minister of State for Space announced a vision of debris-free space by 2030 while opening a debris-removal startup's Hyderabad facility.
Space debris means non-functional, human-made objects in Earth orbit or re-entering the atmosphere, as the UN COPUOS mitigation guidelines define it. More debris raises collision risk for working satellites. ISRO's Debris Free Space Mission (DFSM) seeks debris-free missions by all Indian space actors by 2030. On 5 November 2026, the Minister of State for Space restated that vision.

Why this matters for UPSC
GS3 science and technology: space technology, space debris and space situational awareness. Prelims can ask about IS4OM, NETRA and the COPUOS guidelines; Mains, the sustainable use of outer space.
In short
Space debris is non-functional, human-made material in Earth orbit or re-entering the atmosphere. Its growth threatens satellites everyone depends on, while the rules that govern it remain voluntary.
India should turn DFSM's 2030 goal into binding national disposal rules for every operator, while building its own tracking and pressing for firmer global norms.
Why it matters
A fisherman reading a weather alert, a truck driver using satellite navigation and a family watching television all depend on satellites in orbit. One collision can destroy a working satellite and scatter fragments into paths that other satellites use, so a single accident raises the danger for every operator. Because space is shared, no country can keep its own orbits clean alone: one careless launch puts everyone at risk. Pieces that survive re-entry can also fall on land or sea. Rules that make every operator plan a satellite's disposal before launch, and tracking that warns of close approaches in time, decide whether the orbits around Earth stay usable for the next generation.
Prelims pointers
- The IADC, a body of space agencies, gave COPUOS its consensus debris mitigation proposals in 2003; COPUOS, a UN committee, then drew up its own guidelines.
- Under the Liability Convention, a launching State is absolutely liable for damage its space object causes on the Earth's surface or to aircraft in flight.
- For damage in space to another State's space object, the Liability Convention holds the launching State liable only when it, or those it answers for, was at fault.
- COPUOS adopted the Guidelines for the Long-term Sustainability of Outer Space Activities in 2019; they are voluntary, developed by its Scientific and Technical Subcommittee's working group.
- The COPUOS mitigation guidelines say intentional break-ups, when necessary, should happen at low altitudes so that fragments stay in orbit only briefly.
- The 1968 Rescue Agreement requires States Parties to return foreign space objects found on their territory to their owners and to notify the UN Secretary-General.
- By far the largest share of catalogued debris, the COPUOS guidelines note, came from fragmentation of spacecraft and launch vehicle orbital stages.
Practise a UPSC-style question
With reference to the Space Debris Mitigation Guidelines of the Committee on the Peaceful Uses of Outer Space (COPUOS), consider the following statements:
1. The United Nations General Assembly endorsed these guidelines in 2007.
2. These guidelines are legally binding on States under international law.
3. These guidelines were built on the technical content of the IADC's space debris mitigation guidelines.
Which of the statements given above is/are correct?
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Show the answer
Answer: (c) 1 and 3 only
Answer: (c) 1 and 3 only. The guidelines were endorsed in 2007 and drew on IADC work, but they are voluntary.
Statement 1: correct. General Assembly resolution of 22 December 2007 endorsed the COPUOS Space Debris Mitigation Guidelines.
Statement 2: incorrect. The guidelines say they are not legally binding under international law; States apply them voluntarily through national mechanisms.
Statement 3: correct. A COPUOS working group developed them from the technical content and basic definitions of the IADC guidelines.
Eliminate: statement 2 is wrong, as the text itself calls the guidelines non-binding, so every option with 2 goes. Out: (a), (b), (d).
Trap: Wrong scope. A UN General Assembly endorsement sounds like binding law, but it endorsed voluntary guidelines.
Remember: COPUOS debris guidelines: endorsed by the UNGA in 2007, voluntary, rooted in the IADC's guidelines.
