 The insurance value is further constrained by timeline: Mars provides genetic diversity preservation (500-10K people threshold) within decades, but technological independence (100K-1M+ people for self-sustaining industrial civilization) requires a century or more. During the Earth-dependent phase, slow-developing catastrophes (70-year civilizational collapse) would sever the supply chain before Mars achieves independence. Insurance works for sudden location-correlated events (asteroid impact) but not gradual collapse scenarios.

+DART's successful demonstration of kinetic asteroid deflection at both local and heliocentric scales represents the most significant planetary defense milestone to date, but explicitly does not address the non-asteroid categories of location-correlated extinction risk (supervolcanism, GRBs, solar events) that form the core argument for multiplanetary settlement. The source explicitly notes: 'Even at 100% NEO survey completion and 100% kinetic impactor reliability, asteroid deflection addresses ONLY the asteroid impact category of existential risk.'

 However, planetary defense does not address several other extinction-level threats: (1) gamma-ray bursts from stellar events, which provide no warning and cannot be deflected; (2) supervolcanic eruptions, which are terrestrial and unaffected by space-based deflection; (3) anthropogenic catastrophe including nuclear war, engineered pandemics, or AI misalignment; (4) long-period comets with short warning times that may not provide sufficient lead time for deflection.
 
-This distinction sharpens the multiplanetary imperative's specific rationale: planetary defense is a critical risk reduction tool for one category of extinction threat, but multiplanetary expansion remains the only comprehensive hedge against the full spectrum of existential risks. The success of DART validates one layer of defense while simultaneously highlighting what it cannot protect against.

+DART's 2026 validation of kinetic deflection at heliocentric scale confirms asteroid deflection capability is maturing, but NEO survey completion remains at only 45% of 140m+ objects as of 2025. Vera Rubin Observatory will push to 60%, NEO Surveyor (launching September 2027) will reach 76% within 5 years and 90% by ~2039. Even at 100% survey completion and 100% deflection reliability, planetary defense only addresses the asteroid impact category—not supervolcanism, gamma-ray bursts, nearby supernova, solar events, engineered pandemics, AI misalignment, or nuclear war.
