A spacecraft blasted off Monday to investigate the scene of a cosmic crash. The European Space Agency's Hera spacecraft rocketed away on a two-year journey to the small, harmless asteroid rammed by NASA two years ago in a dress rehearsal for the day a killer space rock threatens Earth. It's the second part of a planetary defense test that could one day help save the planet.
