DART won’t make asteroid crash with Earth

NASA’s DART spacecraft didn’t nudge its target asteroid toward Earth, but there might be other space rocks of a similar size on a collision course with our planet — and that’s why DART’s mission is so important.

DART smashed into the 525-foot-wide (160 meters) asteroid moonlet Dimorphos as planned Monday evening (Sept. 26), successfully demonstrating the “kinetic impact” strategy of planetary defense. The dramatic impact sparked lots of speculation on the internet that NASA may have inadvertently sent an otherwise harmless space rock toward Earth.
