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 odds that asteroid 2024 YR4 could hit Earth in 2032 recently ... the possibility of an impact when the asteroid makes a close ... it as part of its Double Asteroid Redirection Test, or DART.
2024 YR 4 is an asteroid with an estimated diameter of 40 to 90 metres (130 to 300 ft) that is classified as an Apollo-type (Earth-crossing) near-Earth object.From 27 January to 20 February 2025, it had an impact rating of 3 on the Torino scale, with a maximum estimated probability of 3.1% that it would impact Earth on 22 December 2032.
The asteroid YR4's chances of impact now surpass the odds that Apophis once had of colliding with Earth when it was first discovered in 2004. Fortunately, the 130 to 300-foot asteroid is much ...
The goal of the DART mission was to carry out a full-scale test of asteroid deflection technology on behalf of planetary defense and to see whether a kinetic impact — like crashing a spacecraft ...
