Large asteroids could pose a threat to earth so we are looking at ways of preventing such impacts with ESA's preliminary Asteroid Impact Mission (AIM).
One of the main objectives of AIM is to get a better understanding of what asteroids are made of as this is crucial to improving deflection technologies which will be able to set them off a collision course.
