NASA launched its Double Asteroid Redirection Test, or DART, was launched on a Space X Falcon 9 rocket in November, with the aim of smashing into a near-Earth asteroid at 15-thousand miles per hour.
The spacecraft will attempt to knock the asteroid off the course of a potential collision with Earth.
Planetary defence is not something we often think about but it is vital to one day saving the world from dangerous asteroids, comets or any other object from space headed towards our planet.

소행성에 충돌해 궤도 바꾸는 DART 우주선이 작년 11월에 처음으로 발사되었다.우주선 다트의 타깃은 소행성 '디디모스'(Didymos)와 위성 '디모포스'(Dimorphos)이며 2022년 9월 26일부터 10월 1일 중 디디모스와 디모포스의 거리가 가장 가까울 때 디모포스에 충돌시킬 예정이다. 실험 성공 시 향후 소행성 충돌 막을 방안 기술 개발에 기여할것으로 보인다.
