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.<\/p>\n

What are the previous instances of asteroid strikes on Earth?<\/h5>\n

On average about 17 meteorites of substantial size hit the Earth every day (smaller ones burn up due to friction in the atmosphere).<\/p>\n

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\u2019s 180 km wide and 2 km deep.<\/p>\n

In 1908, when a large meteorite smashed into an uninhabited part of Siberia with a force equivalent to a large nuclear bomb.<\/p>\n

What are the advantages of the DART Mission?<\/h5>\n

a)<\/strong> Directly addresses a long-standing nightmare of mass extinction, b)<\/strong> It tests proof of concept for a planetary defence system, which could prevent a large asteroid from smashing into the Earth, or making a close fly-by with disastrous consequences, c)<\/strong> Since DART appears to have worked, scientists can now conceive a similar mission possibly involving a large nuclear warhead if there\u2019s a future emergency.<\/p>\n

What are the challenges with missions like DART?<\/h5>\n

-DART was planned for several years, and the vehicle was launched in November 2021 in order to intersect Dimorphos ten months later.<\/p>\n

– Given mankind\u2019s propensity for weaponising everything, such missions could also be used for military purposes.<\/p>\n

What is ahead after the DART Mission?<\/h5>\n

The Observational capabilities<\/strong> will need to be good enough to observe the potential impact with enough time if there is indeed a hazardous object heading on a collision course.<\/p>\n","protected":false},"excerpt":{"rendered":"
