The Dart spacecraft has sighted the target. On September 26, it will hit an asteroid to divert its trajectory

An asteroid falling to Earth: all we need is this today. However, NASA and ESA, the European Space Agency, are not neglecting the possibility and on September 26 for the first time the American space agency will try to divert the course of an asteroid.

Dimorphos, the large space stone targeted, measures 160 meters in diameter and is comparable to the Colosseum in size.
