An example of an Asteroid issued by NASA
(Picture: PA)Nasa will smash a spacecraft into an asteroid to check Earth’s defences against getting hit by a giant space rock.
The Double Asteroid Redirection Test is now less than a fortnight away and will see the craft - which was launched a year ago - hit the small asteroid head-on as a practice run to protect against some 30,000 similar flying rocks zooming around the solar system.
