A later failure of the collision avoidance system, which was relying upon inaccurate position and velocity information, allowed DART to ultimately collide with MUBLCOM at a relative speed of approximately 1.5 meters per second. Both spacecraft survived the collision without apparent damage.
The collision shortened Dimorphos' orbit by 32 minutes, greatly in excess of the pre-defined success threshold of 73 seconds. [7] [8] [9] DART's success in deflecting Dimorphos was due to the momentum transfer associated with the recoil of the ejected debris, which was substantially larger than that caused by the impact itself.

The last complete image of asteroid moonlet Dimorphos was taken by the DRACO imager on NASA's DART mission at a distance of about 7 miles (12 kilometers) and 2 seconds before impact.
The spacecraft, known as Double Asteroid Redirection Test (Dart), is expected to collide with the 170-metre wide (560ft) asteroid at 00:14 UK time on September 27. (PA Graphics)
The 22 January 2013 collision between debris from Fengyun FY-1C satellite and the Russian BLITS nano-satellite. The 22 May 2013 collision between two CubeSats , Ecuador's NEE-01 Pegaso and Argentina's CubeBug-1 , and the particles of a debris cloud around a Tsyklon-3 upper stage ( SCN 15890) [ 2 ] left over from the launch of Kosmos 1666 .
When NASA sent its DART spacecraft to slam into the asteroid Dimorphos in 2022, the U.S. space agency demonstrated that it was possible to change a celestial object's trajectory, if needed, to ...
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.
