Nuclear warheads ‘could destroy asteroids’

The proposed two-section spacecraft would consist of a kinetic energy impactor that would break off to blast a crater in the asteroid.

The second part would carry the warhead, which would be exploded inside the crater following impact.

The ultimate aim of this would be to break the asteroid up into many different pieces, which would then follow new trajectories away from Earth - and any fragments that did reach the planet would be destroyed in the atmosphere.
