Space Missions & Technology
DART Kinetic Impact Test
A completed test of changing an asteroid moonlet's motion through a spacecraft impact.
Why it matters
Measured outcomes help assess kinetic impact as one potential response to a future hazardous object.
Specific hardware / mission operations
Overview
DART struck Dimorphos in 2022 as a planetary-defence demonstration. The target was not on a collision course with Earth. The experiment tested a method rather than deploying a universal asteroid shield.
Educational reference, reviewed . This page is not a live mission-status report.
How it works
The spacecraft transferred momentum through impact. Astronomers measured the resulting change in the moonlet's orbit around its larger companion, comparing observations before and after the event.
Why it matters
Measured outcomes help assess kinetic impact as one potential response to a future hazardous object.
