DART space probe  

Definición

  • Double Asteroid Redirection Test (DART) is a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. The asteroid selected for the test poses no actual threat to Earth and was selected for the convenience of the test. The probe was launched from Earth on 24 November 2021, and on 26 September 2022 intentionally crashed into Dimorphos, the minor-planet moon of the asteroid Didymos. On 11 October, NASA declared DART a success, confirming it had shortened Dimorphos' orbital period around Didymos by about 32 minutes, surpassing the pre-defined success threshold of 73 seconds.
