Orbital Debris Requires Prevention and Mitigation Across the Satellite Life Cycle

Key Contributions

• Frames debris as a lifecycle problem requiring intervention at every phase: design, launch, operations, post-mission disposal, and active removal
• Documents 1.2 million+ debris fragments larger than 1 cm currently in orbit, with 40,000+ tracked objects
• Argues that mitigation alone is insufficient — active debris removal (ADR) is necessary to stabilize the orbital environment
• Proposes integrated approach combining prevention (design-for-demise, passivation) with active intervention

Key Claims

• Current debris growth rate means Kessler Syndrome risk is increasing even with 100% compliance on new missions
• Post-mission disposal compliance remains below targets — many operators fail to deorbit within guidelines
• ADR of 5-10 large objects per year needed to stabilize LEO environment (consistent with ESA/NASA modeling)
• Economic case for debris mitigation: collision risk imposes costs on all operators through avoidance maneuvers and insurance

Data Points

• 1.2 million fragments >1 cm in orbit
• 40,000+ tracked objects
• Collision avoidance maneuvers increasing year-over-year for constellation operators
• Post-mission disposal: 25-year guideline being reduced to 5 years (ESA) and proposed 5-year rule (FCC)
