Space Debris: Liability Gaps and Reforms Needed
Why in the news
A 500 kg metal object dropped in Makueni County, Kenya, on 30 December 2024. The Kenya Space Agency identified it as a rocket separation ring, though some experts doubted this. The case revived worries about debris accountability.
Key facts
- The Outer Space Treaty (1967) holds states responsible for space activities, whether government or private.
- The 1972 Liability Convention sets absolute liability for damage caused by space objects on Earth.
- Whether debris counts as a “space object” can trigger legal disputes.
- Old or unidentified debris makes it hard to hold the original launching state responsible.
Incidents cited
| Event | Detail |
|---|---|
| Cosmos 954 (Soviet, 1978) | Crashed into Canada with a nuclear reactor; Canada got $3 million of $6 million cleanup cost |
| Long March 5B (China, July 2024) | 23-tonne core stage fell into the Pacific; it has no disposal mechanism |
| SpaceX Falcon 9 (March 2024) | Debris fell in Poland |
| Kenya (30 Dec 2024) | 500 kg ring in Makueni County |
Concerns
- More launches mean more rockets, satellites and spacecraft in orbit.
- Super-constellations such as Starlink, Amazon Kuiper and Eutelsat OneWeb may put over 100,000 satellites up by 2030.
- Older satellites without deorbit plans add to the clutter.
- Voluntary UN guidelines, including the 25-year deorbit rule, show at most 30% compliance.
Way forward
- Binding global rules through the UN’s COPUOS, with penalties such as launch bans.
- National licences conditional on debris mitigation plans; controlled reentry or graveyard orbits.
- Better tracking tools, like the U.S. Space Fence, for early reentry prediction.
- Reusable rockets and sustainable practices; update the 1972 Convention with an independent tribunal able to enforce rulings.
Exam angle
- Treaty years: Outer Space Treaty 1967; Liability Convention 1972.
- UN body: COPUOS.
- Term to remember: absolute liability of the launching state.
