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]
Original – DART's final 5.5 minutes until impact. 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. Reason Impact video of the DART asteroid redirection test on September 26, 2022. First video of its kind.
Another large asteroid is detected moving towards the North Pole in an identical trajectory to 6645 Venturi. The United States, with consent from world leaders but disagreement from scientists, orders two F-16s to destroy the asteroid with low-yield nuclear weapons. The destruction is successful, though the attacking aircraft are brought down ...
In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...

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.
The impact site was not examined by scientists until 20 years later, when they discovered the asteroid carved a massive area of destruction of around 830 square miles, according to NASA.
