Space Debris Mitigation Guidelines

The space debris mitigation guidelines, developed by the Inter-Agency Space Debris Coordination Committee (IADC) and endorsed by UN COPUOS, establish voluntary best practices for reducing debris creation. Key provisions include: limiting debris released during normal operations, minimising breakup potential (passivation), avoiding intentional destruction that creates long-lived debris, post-mission disposal within 25 years for LEO objects (tightened to 5 years by the FCC for US-licensed satellites), and selecting orbits that limit long-term interference. While voluntary at the international level, many nations have incorporated these guidelines into binding national regulations. The guidelines are periodically updated — most recently to address mega-constellation sustainability.
