A collision cascade in a congested orbital shell forces altitude allocation and breaks the Earth-observation record

Prior state
Low Earth orbit had been filled for fifty years by successive constellation generations under a liability and registry regime written for a sparse orbital environment. Collision avoidance was performed constantly and successfully, debris grew steadily, and each operator's incentive was to occupy useful altitudes first. Weather, climate, agricultural, and disaster-monitoring satellites shared the same shells as communications constellations.
Material change
A collision generates debris that triggers further collisions in a congested shell, rendering a band of altitude unusable for a period measured in decades and destroying or forcing the retirement of much of what occupied it. States respond with binding altitude allocation, mandatory insurance and bonding, active removal obligations tied to launch licences, and a registry with real exclusion authority — the first hard property-like regime in orbit.
Why now
Object density in the most useful shells has been accumulating for five decades, and cumulative collision probability compounds rather than staying constant. The generation of constellations deployed in the 2060s reaches end of life during these years, adding uncontrolled objects to the same band. No specific trigger can be forecast; the timing claim rests on cumulative exposure, and the decade is a plausible rather than a determined location for it.
Mechanism and resistance
The cascade is physical and indifferent to policy. The regulatory response runs through launch licensing and insurance, because those are the levers states actually hold. Resistance comes from operators facing stranded assets and from states unwilling to accept allocation authority over what they regard as sovereign access to space. Active removal is expensive, technically immature at scale, and indistinguishable in capability from a weapon, which makes its authorization a security negotiation as much as an environmental one.
Consequences
Continuity is broken in Earth-observation records that agricultural forecasting, disaster warning, fisheries management, and climate monitoring depend on, and the gap falls hardest on states without their own replacement capacity — precisely those whose agriculture and disaster exposure most require the data. Communications and positioning are degraded and rerouted at high cost. Insurance and bonding raise the cost of access enough to exclude marginal operators, and orbital slots acquire scarcity value. The event ends the treatment of orbit as an unmanaged commons.
End state
A useful orbital band is unusable, binding altitude allocation with insurance and removal obligations is in force, and Earth-observation continuity is being reconstructed with a documented multi-year gap in several long records.
Observable test
Catalogued debris in the affected shell rises by a large multiple and remains elevated, launch licensing incorporates binding altitude allocation with bonding and removal requirements, and long-running Earth-observation series record a discontinuity.
Disconfirming sign
Collision avoidance, deorbit compliance, and removal keep debris growth linear through the decade, and orbital governance remains voluntary and coordination-based.
