NASA’s mission is to observe an asteroid before hitting it

The spacecraft won’t erase Dimorphos, the moon orbiting the asteroid Didymos, but it’s large enough to leave an impact crater. If all goes well, DART will, for the first time, slightly alter the motion of celestial bodies in space in surprising ways. Mission results could affect how humans react to any space rock that might …
