NASA's various space mission, the Double Asteroid Redirection Test, or DART for short, is scheduled for November 23 at 7:20 p.m. Launched at 2:50 a.m. Iran time. How to distract. Previous NASA maneuvers have shown that the impact of such asteroids on Earth could have irreversible consequences. They are placed in the path of an approaching asteroid to change the motion of the space rock with a strong impact.
- collision with an asteroid; NASA Mission to Test Earth Protection Operation
The goal of NASA's new mission in this area is a dual asteroid called "Dydimos". The object is actually made up of two space rocks moving in pairs, including a larger asteroid about 780 meters in diameter and a smaller moon-like object about 160 meters in diameter. NASA intends to It targets a smaller object and hopes that during this operation the asteroid's speed will be reduced to such an extent that ground-based telescopes can study the effects of the collision in detail.

If all Things go according to plan, the dart spacecraft in a suicide mission at a staggering speed of about 24,000 kilometers per hour hits the surface of the asteroid and is completely destroyed at the moment, but according to NASA, such a severe impact clearly affects the asteroid and causes The fraction size will be reduced by one percent of its velocity.
Although this change is small, it will slow down the asteroid's orbital period for a few minutes, allowing astronomers to study the impact of the collision. In addition, a dart mission spacecraft operated by the Italian Space Agency in collaboration with the European Space Agency is called the "Italian Light CubeSat for Imagine Asteroids" or "LICIACube". It will fly close to the asteroid to closely observe the effects of the collision. From our planet, under observation. The agency has so far discovered more than 8,000 asteroids with a diameter of more than 140 meters. These objects are so large that, for example, they could destroy an entire state if they hit the United States. None of these objects are currently considered a threat to Earth for the next century, according to NASA.
