A NASA spacecraft has rammed an asteroid in an unprecedented test to see if a potentially menacing space rock could be knocked off course. The galactic grand slam occurred at a harmless asteroid 7 million miles away Monday.
NASA’s first planetary defense test, known as DART, sent a spacecraft crashing into an asteroid at 14,000 mph to knock it off course. In the coming weeks scientists will study the effectiveness of the impact and if it holds promise for future missions.
