A massive asteroid is coming near to the Earth, and it might collide to the Earth’s surface. The asteroid is named “Killer Double Asteroid,” and to fight the deadly asteroid, NASA and ESA are planning to deflect the asteroid system called Didymos. The mission is to distract the system somehow as it contains space rocks measuring 2,500 feet with moons worth 540 feet. NASA announced the making of a program named the Double Asteroid Redirection Test also called DART. The plan is to crash a spacecraft into the massive asteroid to avoid the collision on Earth. It is going to be a first-ever attempt to distract the position of an asteroid by using the kinetic impactor technique.

In context to Europe’s contribution to the test, researcher Brian May said that it is tough to attempt such operation. Crashing into a distant object, which is 160 meters wide, is going to be very tough. Europe is going to follow NASA‘s DART mission on Didymos by sending Hera to study the effect of DART on the asteroid. “Hera will carry two CubeSats on board, which will be able to fly closer to the asteroid’s surface, carrying out crucial scientific studies, before touching down,” ESA explained in a statement. “Hera’s up-close observations will turn asteroid deflection into a well-understood planetary defense technique.” The asteroids are smaller than planets, and they revolve around the Sun. They have enough power to cause destruction on Earth and its human life, including shock waves, tsunamis, and high-speed winds. Recent news said that the asteroids 2019 NN3, 2019 MB4, 2019 MT2, 2006 QV89, 2016 NO56M, RF12, and others were supposed to pass through Earth but our planet turns out to be lucky enough. There are more than 8 lakh asteroids found in space by the astronomers and organizations. The asteroids generally situated in the area called “the main belt” which are present in between the planets Mars and Jupiter.

Talking about 2019 NN4, NASA discovered NN4 first time, and the asteroid is more significant than the Chicago Water Tower. CNEOS first observed on May 8, 2019, and it is going to reach Earth on June 20, 2027. The Double Asteroid Redirection Test also called DART is a mission associated with Goddard Space Flight Center (GSFC), Langley Research Center (LRC), the Jet Propulsion Laboratory (JPL), and Johnson Space Center (JSC). The motive of DART is to stop the space trouble heading towards the Earth. It works on the principle of the Kinetic Impactor technique, allowing them to distract the coming celestial object from colliding. The DART mission is on its Phase C, and APL is managing the current operation of the purpose. The task is to change the direction of the asteroid. The probe is under testing at Marshall Space Flight Center controlled at Washington in the Science Mission Directorate’s Planetary Science Division. The coming asteroid body is under observation from the telescopes on Earth, allowing scientists to countdown the collision days as well as the plans to dodge the imminent trouble. The DART spacecraft is using the NASA Evolutionary Xenon Thruster- Commercial also called NEXT-C.


  1. It is unlikely that the kinetic impact will work because of the internal structure of near-Earth asteroids is crumbly: “We think they’re very loose aggregates. They’re not solid through and through” said Melissa Morris, OSIRIS-REx deputy program scientist at NASA Headquarters in Washington, D.C. The detailed photos and probe impacting of Bennu and Ryugu reveal rubble-pile natural properties of the NEOs, which will prevent shock wave propagation and proper impulse transfer.
