Spaceship launch… September next year
Observe whether the asteroid’s path has changed

A spacecraft has been launched from the United States to test whether the orbit of an asteroid can be changed by striking a specific object. In the future, when an asteroid and the Earth actually collide, it is trying to develop a defense technology to save humans and other living things on Earth.
The National Aeronautics and Space Administration (NASA) launched a spacecraft to perform the ‘Double Asteroid Reorientation Experiment (DART)’ on a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California at 10:21 pm (local time) on the 23rd. did.
The mission of the 620 kg DART spacecraft, which NASA broadcasted live through the Internet, is to test whether it can artificially change its flight trajectory when an asteroid is likely to collide with Earth. To this end, the DART spacecraft will approach the solar system asteroid Didymos (780 m in diameter) and the asteroid Dimorphus (160 m in diameter) orbiting around Didymos in September next year. At this time, the distance from Earth is 11 million km. NASA plans to see if it can change its orbit by colliding the DART spacecraft with Dimorphos at 24,000 km/h.
Dimorphus is not likely to collide with Earth now or after the experiment, but it is trying to see if it can change its orbit with a physical impact when an asteroid that has a real possibility appears. If the experiment is successful, it will give us a way to respond when there is a possibility that the Earth will actually be harmed by an asteroid.
The scientific community believes that if an asteroid with a diameter of 300m collides with the Earth, it will destroy the continents, and if it exceeds 1km, it will cause great damage to the entire planet.
