This approach is deemed crucial for dealing with large space rocks or asteroids with short warning times, where other deflection methods, such as Nasa’s Dart mission, may not be effective. The proposed method involves a spacecraft releasing a penetration device to excavate a deep crater on the asteroid, into which a nuclear device is then guided for detonation. Simulations indicated that an explosion equivalent to 200 Hiroshima bombs could completely destroy an asteroid approximately 100 metres across, with burying the bomb 30 metres deep tripling its effectiveness. The research provides a vital foundation for planning and designing defences against large or short-warning-time asteroids, suggesting nuclear blasts could be the most effective means of protection.
