Why is a NASA spacecraft crashing into an asteroid?

In the to start with-of-its type, save-the-globe experiment, NASA is about to clobber a compact, harmless asteroid tens of millions of miles away. A spacecraft named Dart will zero in on the asteroid Monday, intent on slamming it head-on at 14,000 mph (22,500 kph). The impression should really be just adequate to nudge the asteroid into a somewhat tighter orbit all over its companion place rock — demonstrating that if a killer asteroid ever heads our way, we’d stand a battling opportunity of diverting it.
