Collision with operational satellites

Risk of a decommissioned or uncontrolled satellite colliding with active spacecraft, potentially creating a cascading debris event (Kessler Syndrome).

ISO 24113 — Space Debris Mitigation International
ISO 24113 — Space Debris Mitigation Technical

This document defines the primary space debris mitigation requirements applicable to all elements of unmanned systems launched into, or passing through, near-Earth space, including launch vehicle orbital stages, operating spacecraft and any objects released as part of normal operations.

Obligations (2)

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.
