As of April 2025, only 44% have been catalogued — a dramatic failure of the mandate nearly 20 years later. + +**Detection Gap:** For extinction-level objects (>1km), ~95% are already tracked with none posing near-term threats.

Proven deflection technique for detected rubble-pile asteroids (response) + +## Limitations + +NEO Surveyor does not address long-period comets (LPCs) arriving from the outer solar system with only weeks to months of warning — far too short for kinetic deflection. LPCs remain an unaddressed category of planetary impact threat. + +## Timeline + +- **2005** — Congressional mandate to identify 90% of NEOs >140m by 2020 +- **2020** — Mandate deadline missed; only ~44% catalogued +- **September 2027** — Planned launch (NET) +- **~2032** — Expected completion of 2/3 detection goal + +## Related Missions + +- **DART:** Validated kinetic impactor deflection technique +- **China kinetic impactor test:** 2026 launch target for hybrid deflection/observation test + +## Funding Context + +NASA's planetary defense budget grew from ~$4M/year in early 2000s to ~$200M/year currently, split between: +- Ground-based observations: ~$40M/year +- Flight missions: remainder + +Despite budget growth, the 20-year detection gap reveals a governance failure where mandate and funding were misaligned. \ No newline at end of file
