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]
2024 YR 4 is an asteroid that is classified as an Apollo-type (Earth-crossing) near-Earth object, with an estimated diameter of 40 to 90 metres (130 to 300 ft).As of 23 February 2025, it has a rating of 0 on the Torino scale, with a 1-in-36,000 (0.0039%) chance of impacting Earth on 22 December 2032, [7] and a rating of −3.08 on the Palermo scale, corresponding to an impact hazard 0.8% of ...
In 2022, NASA launched the Double Asteroid Redirection Test (DART) spacecraft, whose sole goal was to fly 7 million miles to the 525-foot asteroid Dimorphos, and crash into it at 14,000 miles per ...
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 ship successfully slammed into the tiny asteroid Dimorphos at 7:14 p.m. Monday, the space agency announced.
Ever since we learned that an asteroid sucker punched the dinosaurs 66 million years ago, we’ve been a little bit worried it might happen again, but with us in the crosshairs. Countless movies ...

The pioneering NASA spacecraft has made make science fiction a reality - or at least that’s the theory.
