NASA spacecraft to test asteroid defence concept

NASA's mission to smash a spacecraft into an asteroid to test if it can be knocked off course is speeding ahead. The DART spacecraft, short for Double Asteroid Redirection Test, lifted off as part of a $330 million project to determine if Earth could be saved from rocks from space. That story by Deborah Groarke for SBS News, produced by Praba Maheswaran for SBS Tamil.
