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]
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 Double Asteroid Redirection Test spacecraft, or DART, collided with Dimorphos, a small asteroid measuring 525 feet in diameter that is located roughly 7 million miles from Earth, at 7:14 p.m ...
The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] 2024 indicates the discovery year, the first letter, "Y", indicates that the asteroid was discovered in the second half-month of December (16 to 31 December) of that year, and "R 4" indicates that it was the 117th provisional ...
On 24 November 2021, NASA and the Applied Physics Laboratory launched an impactor spacecraft towards Dimorphos as part of their Double Asteroid Redirection Test (DART). [33] [34] DART was the first experiment conducted in space to test asteroid deflection as a method of defending Earth from potentially hazardous asteroids. [35]
The spacecraft, known as Double Asteroid Redirection Test (Dart), is expected to collide with the 170-metre wide (560ft) asteroid at 00:14 UK time on September 27. (PA Graphics)
The asteroid redirect vehicle would demonstrate the "gravity tractor" planetary defense technique on a hazardous-size asteroid. This method leverages the mass of the spacecraft (18 tons [ 44 ] ) and its 6m boulder cargo (at least 20 tons [ 45 ] ) to impart a gravitational force on the asteroid, slowly altering the asteroid's trajectory.
The pioneering NASA spacecraft has made make science fiction a reality - or at least that’s the theory.
