Abstract The impact of the Double Asteroid Redirection Test spacecraft into Dimorphos, moon asteroid Didymos, changed Dimorphos’s orbit substantially, largely from ejection material. We present results 12 Earth-based facilities involved in a world-wide campaign to monitor brightness and morphology ejecta first 35 days after impact. After an initial brightening ∼1.4 mag, we find consistent dimming rates 0.11–0.12 mag day −1 week, 0.08–0.09 over entire study period. system returned its...
The impact of the DART spacecraft into Dimorphos, moon asteroid Didymos, changed Dimorphos' orbit substantially, largely from ejection material. We present results twelve Earth-based facilities involved in a world-wide campaign to monitor brightness and morphology ejecta first 35 days after impact. After an initial brightening ~1.4 magnitudes, we find consistent dimming rates 0.11-0.12 magnitudes/day week, 0.08-0.09 over entire study period. system returned its pre-impact 24.3-25.3 through...
