The LICIACube nanosatellite was released on 11 September 2022, 15 days before the impact. [71] Four hours before impact, some 90,000 kilometres (0.23 LD; 56,000 mi) away, DART began to operate in complete autonomy under control of its SMART Nav guidance system. Three hours before impact, DART performed an inventory of objects near the target.
The DART spacecraft streamed these images from its DRACO camera back to Earth in real time as it approached the asteroid. This replay movie is 10 times faster than reality, except for the last six images, which are shown at the same rate that the spacecraft returned them. Both Didymos and its moonlet Dimorphos are visible at the start of the movie.

LICIACube is the first deep space mission developed and autonomously managed by an Italian team. To collaborate upon the design, integration, and testing of the CubeSat, the Italian Space Agency selected the aerospace company Argotec, while the LICIACube GS has a complex architecture based on a mission control center in Turin hosted by Argotec and science operation center in Rome.

Animation of DART around Didymos - Impact on Dimorphos DART · Didymos · Dimorphos. The primary body of the binary system, Didymos, orbits the Sun at a distance of 1.0 to 2.3 AU once every 770 days (2 years and 1 month). The pathway of the orbit has an eccentricity of 0.38 and an inclination of 3° with respect to the ecliptic.
Infographic showing the effect of DART's impact on the orbit of Didymos B with deployment of LICIACube. Initially, Hera 's role was to be realized by a much larger spacecraft called Asteroid Impact Mission (AIM), [12] that would have observed the plume, the crater, and the freshly exposed material to provide unique information for asteroid deflection, science and mining communities.
