Overview
On 30 July 2026, the IN‑SPACe released the ‘Authorisation for Undertaking Planned Re‑entry of Space Objects’ guidelines. These rules set a clear framework for how government agencies and private firms must manage the re‑entry phase of satellites, rockets and other space objects.
Key Developments
- Definition of planned re‑entry and its procedural requirements.
- Mandatory survivability analysis and submission of a fragmentation pattern.
- Adoption of the international 1‑in‑10,000 risk limit as the safety benchmark.
- Requirement of third‑party liability insurance under the 1972 Liability Convention.
- Coordination with aviation and maritime authorities through NOTAMs and NAVAREA warnings.
Important Facts
The guidelines apply only to objects that are expected to survive re‑entry, such as reusable rocket stages, crewed capsules, or heavy engine parts made of titanium or stainless steel. If an object is designed to burn up completely, a special permit is not required. Operators must use sophisticated software to model the re‑entry corridor, accounting for wind, atmospheric density and population density. If the calculated probability of a surviving fragment hitting a person exceeds 0.01%, the mission is deemed unsafe and must be redirected to a remote “spacecraft cemetery” in the South Pacific.
Compliance also demands that operators obtain an advisory note from IN‑SPACe at least 45 days before the planned re‑entry, enabling the issuance of NOTAMs and NAVAREA alerts to keep aircraft and ships away from the predicted debris footprint.
