Week in Space Data, every Friday.
Comprehensive sustainability ratings for space operators. Tracking debris mitigation, disposal compliance, collision avoidance, data transparency, and environmental impact across the global space industry.
Aggregate score across all tracked operators and criteria. Weighted equally across 5 categories, each scored 0-20.
Adherence to international debris mitigation standards and guidelines
Quality and reliability of end-of-life spacecraft disposal planning
Active maneuvering and conjunction assessment participation
Sharing of orbital data, ephemeris, and operational status with the community

Improving, ASAT test debris
ASAT debris, improving practices
ASAT debris, limited compliance
Historically, operators had 25 years to deorbit LEO spacecraft post-mission. The FCC now requires 5 years for new US-licensed satellites, and international bodies are considering similar reductions. This dramatically reduces long-term orbital congestion.
All stored energy sources (batteries, fuel tanks, pressure vessels, reaction wheels) must be depleted at end of life to prevent accidental explosions that generate debris. This is one of the most cost-effective debris mitigation measures.
Satellites should be designed to be trackable by ground-based SSA systems. This includes minimum radar cross-section requirements, retroreflectors for laser ranging, and active transponders for cooperative tracking.
Operators should participate in conjunction assessment programs (e.g., 18th SDS, EU SST) by sharing high-accuracy ephemeris data and responding to collision avoidance warnings in a timely manner.
Every mission must include a credible disposal plan, either controlled reentry, graveyard orbit transfer, or natural deorbit within the required timeframe. Plans must account for propulsion failures with passive backup strategies.
Federal Communications Commission (FCC)
Requires all new US-licensed LEO satellites to deorbit within 5 years of mission end, down from the previous 25-year guideline. First binding regulatory requirement of its kind.
United Nations COPUOS
Long-term Sustainability Guidelines for Outer Space Activities. Non-binding but influential framework covering debris mitigation, SSA data sharing, and sustainable space operations.
International Organization for Standardization
International standard for space debris mitigation requirements. Covers mission planning, design, manufacturing, launch, operations, and disposal phases.
European Space Agency
Comprehensive debris mitigation requirements for all ESA missions. Includes Zero Debris Charter target of zero new debris by 2030. More stringent than IADC guidelines.
Inter-Agency Space Debris Coordination Committee
Foundational guidelines developed by 13 space agencies. Covers limiting debris during normal operations, minimizing breakup potential, post-mission disposal, and collision avoidance.
Scores are derived from publicly available data including regulatory filings, UN COPUOS reports, published debris mitigation plans, conjunction assessment participation records, and third-party analyses from organizations including the Secure World Foundation, European Space Agency, and the Space Safety Coalition. Each operator is scored across five equally weighted categories (0-20 points each) for a maximum total of 100 points. Scores are updated quarterly and reflect both current practices and historical track records. This scorecard is for informational purposes and does not constitute an official regulatory assessment.
