What is the News?<\/b><\/h5>\n

NASA\u2019s DART (Double Asteroid Redirection Test) spacecraft has collided with the asteroid Dimorphous.<\/span><\/p>\n

What are Asteroids?<\/b><\/h5>\n

Asteroids are <\/span>small, rocky objects that orbit the Sun<\/span>. Although asteroids orbit the Sun like planets, they are much smaller than planets.\u00a0<\/span><\/p>\n

There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt \u2013 a region between the orbits of Mars and Jupiter.<\/span><\/p>\n

How did NASA undertook this mission?<\/b><\/h5>\n

NASA undertook the \u2018kick\u2019 technique. Compared to the massive Dimorphos, DART is a tiny Goliath.\u00a0<\/span><\/p>\n

Yet crashing at a breakneck speed of 23,760 kilometres per hour, the momentum is adequate to slash the angular momentum of Dimorphos, making it speed up and move closer to Didymos.\u00a0<\/span><\/p>\n

All of these reduce the orbital period and the time taken for the moonlet to go around the primary asteroid. The pair\u2019s trajectory is thus deflected as the net result of these dynamics.\u00a0<\/span><\/p>\n

Consider it like this: a fast-moving moped slamming into a truck is sure to undergo a massive crash and burn, yet will veer the massive truck a bit. This is the essence of the \u2018kick\u2019 technique.<\/span><\/p>\n

What has been the impact assessment?<\/b><\/h5>\n

The DART craft carried a high-resolution DRACO (Didymos Reconnaissance and Asteroid Camera for Optical navigation) camera to observe the collision and its consequences. The <\/span>close-up images until its fatal crash are being analyzed.<\/span><\/p>\n

Are there other countries launching similar missions?<\/b><\/h5>\n

China is set to deflect a 40 m diameter earth-crossing asteroid called 2020 PN1 sometime in 2026.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
