DART would then kinetically impact the asteroid's moon on 26 September 2022, during a close approach to Earth. AIM would have orbited the larger asteroid to study its composition and that of its moon. Under that proposal, the European Asteroid Impact Mission (AIM), would have launched in December 2020, and DART in July 2021. NASA and the European Space Agency (ESA) started with individual plans for missions to test asteroid deflection strategies, but by 2015, they struck a collaboration called AIDA (Asteroid Impact and Deflection Assessment) involving two separate spacecraft launches that would work in synergy. The Italian Space Agency contributed LICIACube, a CubeSat which photographed the impact event, and other international partners, such as the European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA), are contributing to related or subsequent projects. The project was funded through NASA's Planetary Defense Coordination Office, managed by NASA's Planetary Missions Program Office at the Marshall Space Flight Center, and several NASA laboratories and offices provided technical support. ĭART was a joint project between NASA and the Johns Hopkins Applied Physics Laboratory. DART's success in deflecting Dimorphos was due to the momentum transfer associated with the recoil of the ejected debris, which was substantially larger than that caused by the impact itself. The collision shortened Dimorphos' orbit by 32 minutes, greatly in excess of the pre-defined success threshold of 73 seconds. Launched on 24 November 2021, the DART spacecraft successfully collided with Dimorphos on 26 September 2022 at 23:14 UTC about 11 million kilometers (6.8 million miles) from Earth. The selected target asteroid, Dimorphos, is a minor-planet moon of the asteroid Didymos neither asteroid poses an impact threat to Earth. It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. Double Asteroid Redirection Test ( DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs).
