And it worked !

[...] the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.

Before its encounter, NASA had defined a minimum successful orbit period change of Dimorphos as change of 73 seconds or more. This early data show DART surpassed this minimum benchmark by more than 25 times.

Dart: Asteroid deflection experiment boosted by debris

BBC News

The Nasa probe that struck an asteroid in September to try to deflect its path had a bigger effect because of all the debris it kicked out.
