Assessment

Why?

Strongest counted support: The Nature Communications model reports that a $200,000 per-satellite disposal bond reduces annual derelict-satellite mass by over one-third and raises welfare by up to 27%. weight 1.800000 evidence

Suppressed as dependent: The excerpt directly reports the $200,000 bond amount, more-than-one-third mass reduction, and up-to-27% welfare increase.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

Evidence for

• The abstract reports modelled effects of a $200,000 bond: more than one-third less derelict mass per year and up to 27% higher welfare.

  The abstract directly reports the bond amount and modelled outcomes.

• The excerpt directly reports the $200,000 bond amount, more-than-one-third mass reduction, and up-to-27% welfare increase.

  From Bonds improve post mission disposal compliance and the sustainability of low Earth orbit Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  The passage explicitly states all quantitative model outputs.

• The preprint-index abstract independently reproduces the reported $200,000 bond model outcomes.

  Secondary abstract reproduction corroborates the primary article; it is not an independent model.

• The study abstract directly reports that $200,000 per-satellite bonds reduce annual derelict mass by over one-third and raise welfare by up to 27%.

  The primary article directly states the bond amount and both modeled outcomes.

• The Nature Communications model reports that a $200,000 per-satellite disposal bond reduces annual derelict-satellite mass by over one-third and raises welfare by up to 27%.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
