NASA’s DART (Double Redirection System) Mission is a rare blue sky science project, which directly addresses a long-standing nightmare of mass extinction. It tests proof of concept for a planetary defence system, which could prevent a large from smashing into the Earth, or making a close fly-by with disastrous consequences. It is known that approximately 66 million years ago, a very large meteorite crashed into the Yucatan region of Mexico and caused the extinction of a large number of animal and plant species. It caused tsunamis and led to a nuclear winter that lasted a long time. It is estimated that the object was around 10 km in diameter and it caused a crater that’s 180 km wide and 2 km deep. Something similar almost happened in 1908, when a large meteorite smashed into an uninhabited part of Siberia with a force equivalent to a large nuclear bomb. Even a large meteorite burning up in the lower atmosphere could damage the ozone layer, or release enough energy to cause damage similar to a nuclear explosion.
