On September 26, 2022, local time, according to CNN, the spacecraft carrying out NASA's "Double Asteroid Redirection Test" (DART) mission was at 26 Eastern Time. It successfully hit an asteroid called Didymos that night.

This is a historic test of humanity's ability to prevent cosmic objects from destroying life on Earth.

During this mission, NASA tested planetary defense technology, and if the orbit of "Dimophos" was changed, it would be the first time that humans have changed the motion of natural celestial bodies in space.
