Full title and description

ISO 23312:2022 — Space systems — Detailed space debris mitigation requirements for spacecraft. This international standard specifies detailed requirements and recommendations for the design and operation of unmanned spacecraft to mitigate generation of space debris in Earth orbit.

Abstract

This document defines detailed space debris mitigation requirements and recommendations applicable to unmanned spacecraft in Earth orbit, including measures to avoid intentional release of debris during normal operations, prevent break-ups in orbit, ensure end-of-mission disposal, estimate remaining usable propellant mass, and develop and maintain a space debris mitigation plan. The document explicitly does not cover nuclear power sources on spacecraft.

Scope

ISO 23312:2022 establishes detailed, implementable space debris mitigation requirements for unmanned spacecraft operating in Earth orbit. The scope covers avoidance of intentional debris release during routine operations, measures to prevent in-orbit break-ups, end-of-mission disposal procedures, methods for estimating remaining usable propellant mass, and the content and maintenance of a spacecraft space debris mitigation plan. The standard is focused on practical design and operational controls to limit debris generation and does not apply to nuclear power sources on spacecraft.

Key topics and requirements

• Design and operational requirements to avoid intentional release of objects or materials that would create debris in Earth orbit.
• Requirements and recommendations to reduce the risk of fragmentation or break-up while in orbit.
• End-of-mission (EOM) disposal requirements, including deorbiting and graveyard-orbit strategies appropriate to the spacecraft's orbit.
• Methods and procedures for estimating the mass of remaining usable propellant to support reliable EOM disposal planning.
• Requirements for preparing, documenting and maintaining a space debris mitigation plan for the spacecraft lifecycle.

Typical use and users

Practitioners who commonly use this standard include spacecraft systems engineers, mission designers, program managers, launch-service providers, satellite operators, regulatory and compliance teams, and organizations preparing mission safety and debris mitigation plans. The standard supports design reviews, mission assurance, licensing/compliance activities, and end-of-life planning.

Related standards

ISO 23312 is part of the ISO family addressing space debris mitigation and interfaces with the top-level ISO 24113 (Space debris mitigation requirements) and supporting technical reports such as ISO/TR 18146 (space debris mitigation design and operation manual). It also replaces a number of earlier, more specific documents (for example ISO 16127:2014, ISO 16164:2015, ISO 23339:2010 and ISO 26872:2019) as consolidated in this 2022 publication.

FAQ

Q: What is this standard?

A: ISO 23312:2022 is an international standard titled "Space systems — Detailed space debris mitigation requirements for spacecraft" that provides detailed requirements and recommendations for preventing the creation of space debris by unmanned spacecraft in Earth orbit.

Q: What does it cover?

A: It covers detailed measures to avoid intentional release of debris, to prevent in-orbit break-ups, to plan and carry out end-of-mission disposal, to estimate remaining usable propellant, and to prepare and maintain a space debris mitigation plan. It does not cover spacecraft nuclear power sources.

Q: Who typically uses it?

A: Satellite and spacecraft engineers, mission and systems architects, operators, launch providers, compliance and licensing teams, and safety/mission assurance staff use this standard to design, evaluate and document debris mitigation measures.

Q: Is it current or superseded?

A: ISO 23312:2022 is published and in force (published July 2022). ISO indicates the document is scheduled for periodic review and a DIS (draft international standard) stage has been recorded in ISO's lifecycle; users should check for any subsequent revisions or replacement documents when planning compliance.

Q: Is it part of a series?

A: Yes — it is part of the ISO space debris mitigation family. ISO 24113 provides top-level debris mitigation requirements, while ISO 23312 supplies more detailed, spacecraft-level requirements; ISO/TR 18146 and other technical reports provide explanatory guidance and implementation advice.

Q: What are the key keywords?

A: Key keywords include space debris, orbital debris mitigation, spacecraft end-of-life, deorbit, graveyard orbit, fragmentation prevention, propellant estimation, debris mitigation plan, and spacecraft operations.
