Obligations (3)

Comply with UN Space Debris Mitigation Guidelines

High

Operators must design missions to limit debris generation during normal operations, minimise breakup potential, and ensure post-mission disposal within 25 years.

Controlled re-entry planning

High

Operators must plan controlled re-entry to ensure debris impacts occur in designated safe ocean areas, minimising risk to populated regions.

Liability for space object damage

High

Under the Outer Space Treaty and Liability Convention, launching states bear international liability for damage caused by their space objects.

Opportunities (1)

Design for demise

High

Engineer satellite components to fully ablate during atmospheric re-entry, eliminating ground impact risk and reducing liability concerns.
