NASA's First Planetary Defense Technology to Collide with Asteroid in __________.

NASA's first mission to demonstrate a planetary defence technique, The Double Asteroid Redirection Test (DART), will get one opportunity to hit small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target. NASA revealed that details about its plan to hit a small moonlet target in a double asteroid system with a spacecraft in 2022. The asteroid, called Didymoon or Didymos B, is a moon asteroid around 150 meters tall orbiting a larger body Didymos A, the most accessible asteroid of its size from the Earth.
