Full title and description

ISO/TR 18146:2020 — Space systems — Space debris mitigation design and operation manual for spacecraft. This technical report provides practical guidance on design and operational practices for launch vehicle orbital stages and spacecraft to mitigate the generation and growth of space debris across their orbital lifetime.

Abstract

This technical report contains information on design and operational practices for launch vehicle orbital stages and spacecraft aimed at reducing space debris. It informs engineers about requirements and recommendations within the family of space debris mitigation standards so that spacecraft are designed, operated and disposed of in ways that minimise debris generation throughout their orbital lifetime.

Scope

ISO/TR 18146:2020 provides a manual-style compendium of design and operational guidance for mitigating space debris, with a focus on launch vehicle orbital stages and spacecraft life-cycle activities (design, operation, end-of-life and disposal). It is intended to support engineers and program managers in applying requirements and recommendations from the family of space debris mitigation standards to reduce fragmentation risk and limit long-term debris growth.

Key topics and requirements

• Design and operational practices for launch vehicle orbital stages and spacecraft to minimise debris generation.
• End-of-life planning and disposal options (including controlled re-entry and transfer to disposal orbits) and guidance on passivation.
• Operational measures to reduce collision risk and fragmentation during mission phases.
• Integration of recommendations from the space debris mitigation standards family into engineering and mission-planning processes.
• Practical considerations for documentation, record-keeping and conformance with debris-mitigation expectations.

Typical use and users

Typical users include spacecraft and launch vehicle designers, mission planners, satellite operators, launch service providers, systems engineers, and national/regulatory authorities engaged in space safety and debris mitigation. The report is used as a practical reference to interpret and implement debris-mitigation requirements within design and operational decision-making.

Related standards

ISO/TR 18146 sits within the broader family of space debris mitigation standards and is commonly used alongside documents such as ISO 24113 (space debris mitigation requirements) and related ISO deliverables covering detailed requirements, orbit lifetime estimation and operational messages. It replaces the earlier ISO/TR 18146:2015 and is referenced in conjunction with other space-systems standards and technical reports addressing debris mitigation and on-orbit operations.

Keywords

space debris mitigation, spacecraft disposal, launch vehicle orbital stages, end-of-life (EOL) planning, passivation, collision avoidance, fragmentation prevention, space sustainability.

FAQ

Q: What is this standard?

A: ISO/TR 18146:2020 is a technical report (manual) that provides guidance on design and operational practices to mitigate space debris for launch vehicle orbital stages and spacecraft.

Q: What does it cover?
