The DART spacecraft will travel to Dimorphos to demonstrate what NASA calls a "kinetic impactor " method. This method involves the spacecraft purposefully crashing into the asteroid at a high speed to change the object's motion in space.

DART航天器将前往二态磷小行星，展示美国宇航局所谓的“动能撞击器”的方法。这种方法是指航天器故意高速撞击小行星以改变该物体在太空中的运动。
