Applications

15.8.1 NEO Discovery Surveys — Systematically detecting, cataloguing and characterising near-Earth objects using space-based infrared and visible survey telescopes before they become impact threats.
15.8.2 Kinetic Impact Demonstrators — Flying a dedicated impactor spacecraft at a small near-Earth asteroid to validate deflection physics, measure momentum transfer, and build national deep-space mission competency.
15.8.3 Deflection Mission Architectures — Designing, validating and operating spacecraft missions capable of physically altering the trajectory of a confirmed Earth-threatening asteroid before impact.
15.8.4 International PD Coordination — A sovereign space-based node contributing real-time threat assessment data and secure communications to the global planetary defence coordination network.
15.8.5 Civil Defence Integration — Connecting planetary defence threat data directly into national civil emergency systems so governments can order evacuations, shelter-in-place, or coordinated response before an impact event unfolds.
