The Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the moon of the (65803) Didymos asteroid system, on 26 September 2022 at 23:14:24.183 UTC. The spacecraft mass at the time of impact was 579.4 ± 0.7 kg, and the impact velocity was 6.1449 ± 0.0003 km/s, resulting in an impact energy of 10.94 ± 0.01 GJ. The impact changed the orbital period of Dimorphos relative to Didymos by -33.0 ± 1.0 minutes, and the initial estimate of the resulting momentum enhancement factor, β, is between 2.2 and 4.9, depending on Dimorphos’s mass.
