The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
The galactic grand slam occurred at a harmless asteroid 7 million miles (9.6 million kilometers) away, with the spacecraft named Dart plowing into the small space rock at 14,000 mph (22,500 kph).
The NASA mission was intended to test whether a spacecraft impact could successfully deflect an asteroid on a collision course with Earth. The DART spacecraft was launched on 24 November 2021, and impacted Dimorphos on September 26, 2022. [28] [29] [30] It was accompanied by the Italian Space Agency's (ASI) six-unit LICIACube flyby Cubesat that ...
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.
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.

Light Italian CubeSat for Imaging of Asteroids (LICIACube, / ˈ l iː tʃ i ə ˌ k j uː b / [4]) is a six-unit CubeSat of the Italian Space Agency (ASI). LICIACube is a part of the Double Asteroid Redirection Test (DART) mission and carries out observational analysis of the Didymos asteroid binary system after DART's impact on Dimorphos.
The double asteroid redirection test (Dart) will test defence technologies for preventing a hazardous asteroid impacting Earth. Skip to main content. Sign in. Mail. 24/7 Help. For premium support ...
