NASA has launched a mission to deliberately smash a spacecraft into an asteroid. The DART (Double Asteroid Redirection Test) spacecraft was successfully launched by NASA. NASA tweeted, “Asteroid Dimorphos: we're coming for you!” NASA also tweeted that about 55 minutes into its flight, the spacecraft separated from the Falcon 9 second stage. The aim of the DART spacecraft is a moonlet called Dimorphos. It is about 160-metre in diameter. The collision is expected to take place next year. NASA said DART's target asteroid is not a threat to Earth currently. Watch the video to know more.
