DART would then kinetically impact the asteroid's moon on 26 September 2022, during a close approach to Earth. [13] The AIM orbiter was however canceled, then replaced by Hera which plans to start observing the asteroid four years after the DART impact. Live monitoring of the DART impact thus had to be obtained from ground-based telescopes and ...
The target spacecraft was an OSC MUBLCOM (Multiple-Path Beyond-Line-of-Sight Communications) prototype communications relay satellite weighing approximately 49 kg (108 lb) launched from Vandenberg Air Force Base on 18 May 1999 with International Designator 1999-026B.
Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...
DART model simulates, simultaneously in several wavelengths of the optical domain (e.g., visible and thermal infrared), the radiative budget and remotely sensed images of any Earth scene (natural / urban with /without relief), for any sun direction, any atmosphere, any view direction and any sensor FTM.

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.

The DART impact on the center of Dimorphos decreased the orbital period, previously 11.92 hours, by 33±1 minutes. This large change indicates the recoil from material excavated from the asteroid and ejected into space by the impact (known as ejecta) contributed significant momentum change to the asteroid, beyond that of the DART spacecraft itself.
