Planetary Defence Drill on 3I/ATLAS: Largest Simulation by ESA
Why in the news
Europe kicked off a global exercise to test how the world would detect, track and respond to a fast near-Earth threat.
Key facts
- Organisers: ESA, NASA and the International Asteroid Warning Network (IAWN) of the UN.
- Test object: 3I/ATLAS, a real target at about 60 km/s.
- Agencies such as ISRO, CNSA and JAXA are among those measured on cooperation.
What the drill tests
| Area | Focus |
|---|---|
| Early warning | Tracking networks and detection of fast movers |
| Emergency response | Deflection missions, civil-defence mobilisation, evacuation |
| Coordination | Data-sharing gaps among space agencies |
| Public communication | Countering misinformation, alerts, psychological readiness |
Exam angle
- Object: 3I/ATLAS; warning body: IAWN.
