Nasa will crash a spacecraft into this asteroid to slow it down by 1%
India TodayRemember the Bruce Willis starred Armageddon, where a group of rag-tag amateur astronauts launched on a mission to deflect an asteroid headed towards Earth? The DART mission will target an asteroid as engineers and astronomers aim to create a defence system able to deflect potential asteroids headed towards Earth in future. "The DART mission is Nasa’s first planetary defence test mission and will impact an asteroid to demonstrate a technique that could be used in the future to protect Earth from a potential impact. Dubbed as Double Asteroid Redirection Test mission, DART is managed under the Solar System Exploration Program by Nasa, which will achieve the kinetic impact deflection by deliberately crashing itself into the moonlet at a speed of approximately 6.6 kilometres per second. Dimorphos, 525 feet in diameter and orbit around the larger main body Didymos, which measures 780 meters and because of its proximity to Earth during 2022, astronomers will be able to compare observations from Earth-based telescopes before and after DART’s kinetic impact to determine how much the orbital period of Dimorphos changed.
