Space agencies worldwide have developed guidelines to combat the growing threat of orbital debris. These standards aim to minimize debris generation throughout a spacecraft's lifecycle, from design to disposal, ensuring responsible space practices.
NASA, ESA, , and have established specific requirements for their missions. These include plans, , and design choices that reduce debris creation. National licensing processes now enforce these guidelines for commercial space activities.

Establishes requirements and procedures for limiting orbital debris generation throughout mission lifecycle
Applies to all NASA programs and projects involving spacecraft, launch vehicles, and instruments in Earth orbit
Mandates assessment of debris generation potential during design and operations phases (ODAR)
Requires implementation of debris mitigation measures such as , disposal orbits, and collision avoidance maneuvers
Encourages use of materials and designs that minimize debris generation upon impact or explosion
ESA Space Debris Mitigation Policy
Outlines ESA's commitment to reducing space debris and preserving the space environment for future generations
Applies to all ESA missions and activities, including spacecraft design, launch, and operations
Requires compliance with (, ) and
Mandates end-of-life disposal strategies such as or placement in
Promotes development and use of technologies that minimize debris generation (shielding, breakup prevention)
JAXA and Roscosmos Debris Mitigation Guidelines
JAXA (Japan Aerospace Exploration Agency) and Roscosmos (Russian Space Agency) have established their own guidelines for mitigating space debris
JAXA guidelines align with international standards and focus on preventing on-orbit breakups, minimizing debris release, and post-mission disposal
Roscosmos general requirements address debris mitigation through spacecraft design, launch vehicle passivation, and end-of-life disposal
Both agencies require compliance with their respective guidelines for all national space missions and collaborate with international partners to promote responsible space practices
Regulatory Compliance
National Licensing Requirements
Many countries have established licensing requirements for space activities to ensure compliance with debris mitigation guidelines
In the United States, the (FCC) and (NOAA) issue licenses for commercial satellites and remote sensing systems, respectively
License applications must demonstrate adherence to orbital debris mitigation practices, including end-of-life disposal plans and collision avoidance capabilities
Other countries, such as the United Kingdom () and France (CNES), have similar licensing processes that incorporate debris mitigation requirements
End-of-Life Disposal Plans
Satellite operators must develop and implement plans for responsible disposal of spacecraft at the end of their operational lives
Common disposal strategies include:
De-orbiting: Maneuvering spacecraft to re-enter Earth's atmosphere and burn up
Graveyard orbits: Moving spacecraft to designated disposal orbits away from operational regions
Direct retrieval: Using robotic servicing vehicles to capture and remove defunct satellites
Disposal plans must consider factors such as spacecraft mass, orbital altitude, and potential hazards to other space objects
International guidelines recommend disposing of spacecraft within 25 years of end-of-life
Mission-Specific Debris Mitigation Strategies
In addition to general debris mitigation guidelines, space agencies and operators may develop mission-specific strategies based on unique spacecraft characteristics and operational requirements
For example, large constellations (Starlink, OneWeb) may employ specialized collision avoidance systems and rapid de-orbiting capabilities to minimize debris risks
Missions in highly congested orbits, such as sun-synchronous orbit, may require enhanced shielding and more frequent collision avoidance maneuvers
Spacecraft with high-power laser or radar systems may need to incorporate additional safeguards to prevent unintentional damage to other space objects
