DART is a demonstration mission to see how kinetic impact could deflect an asteroid's course. In the 2021 DART mission, Didymos and Didymoon are not in fact on a collision course with Earth, but they offer an interesting opportunity for a practice run.

Provided the asteroid is detected early enough. To read more, click here.
