Milestone
DART unfurled both ROSA solar wings
NASA reports completion about two hours after separation. The date is retained without inventing an exact completion time.
Deployment
DART separated from Falcon 9
NASA reports separation at 2:17 a.m. EST. Initial telemetry and preparation for solar-array deployment followed.

Impacted the asteroid moonlet Dimorphos
The original navigation source identifies the official radio-clock impact epoch as23:14:24.183UTC. The catalog represents it to the nearest second; the navigation-fit impact estimate and Earth-reception time are separate.

Source states place the model at the selected time. Reconstructed flight, estimates, predictions and historical mission plans are identified by interval; gaps remain visible.
Source records and sampling assumptions are retained with the repository data. Model attitude and surface appearance are illustrative.
