On Monday, Nasa’s Double Asteroid Redirection Test, or Dart, made history as the first spacecraft to impact an asteroid and change its orbit.

Iran PressAmerica: On Monday, the world watched as a little NASA spacecraft called DART met its explosive end. This box, slightly bigger than an oven and winged with solar panels, had been fated to die since it left Earth in November.  

The Double Asteroid Redirection Test's mission was simple: Crash into a giant asteroid so scientists could see whether that impact nudges the space rock ever so slightly. If so, perhaps a future asteroid on a collision course with Earth can be staved off with a similar spacecraft suicide mechanism -- a way to save humanity and avenge the dinosaurs.
