Explained: Why is Nasa intentionally crashing a spacecraft into an asteroid

When the Dart mission launches on November 24, scientists will be on their toes to attempt a first of its kind event in deep space - crashing a spacecraft purposely in an asteroid. As the spacecraft hits the celestial object, scientists are hoping it will change the orbit of the asteroid and demonstrate a unique planetary defence system. The Didymos binary asteroid system was chosen since it has no chance of heading towards Earth in future and could be an untouched test bed for new technology. The impulse of energy that DART delivers to the Didymos binary asteroid system is low and cannot disrupt the asteroid, and Didymos' orbit does not intersect Earth's at any point in current predictions.”
