Planetary-Defense Exercise on 3I/ATLAS:

Europe has launched the world’s largest planetary-defence drill, centred on tracking the fast-approaching object 3I/ATLAS.
- The 3I/ATLAS planetary-defense drill is the largest global simulation ever conducted to test how nations detect, track and respond to near-Earth threats.
- Led jointly by ESA, NASA, UN-IAWN (International Asteroid Warning Network).
- Aim:
- To evaluate Earth’s readiness for high-velocity objects by testing early-warning systems, tracking networks, emergency coordination and citizen communication.
- Also aims to identify gaps in international cooperation, data-sharing and psychological preparedness.
- Key Features:
- Real object (3I/ATLAS) travelling at ~60 km/s provides real-world complexity.
- Involves planetary-defense modelling, orbital prediction drills and anomaly-response protocols.
- Includes public-communication modules, addressing misinformation and psychological preparedness.
- Uses multi-agency coordination, including defense space commands.
- Parallel geopolitical coordination amid ESA’s record budget and U.S.–China–India moves in space security.
