NASA 's Double Asteroid Redirection Test (DART) hit an asteroid on September 26, 2022 .

An investigation into the debris DART left behind suggests this technique isn’t as straightforward as scientists initially thought.

DART collided with Dimorphos , a small moonlet orbiting a larger asteroid called Didymos .

The researchers analyzed images taken by a satellite that was mounted on the DART spacecraft.

Astronomers have catalogued roughly 2,500 potentially hazardous asteroids in our corner of the galaxy.

There is currently no known risk of one of these asteroids hitting our planet within the next century .

Developing strategies to prevent such a catastrophe could someday prove lifesaving.

The success of the DART mission suggests that NASA is on the right track.
