NASA = National Aeronautics and Space Administration conducted the first experiment on the 26th to hit an asteroid far from the earth in an attempt to develop technology to prevent asteroids from colliding with the earth.
NASA plans to analyze whether the asteroid's orbit has changed in the future.
The experiment, dubbed "DART," launched in November last year involved a probe weighing about 570 kilograms that collided with an asteroid about 11 million kilometers away from Earth, and the impact changed its trajectory. This is the first attempt to confirm.
NASA announced on the 26th that, as planned, the probe collided with the target asteroid "Dimorphos" with a diameter of about 160 meters at a speed of about 22,000 kilometers per hour.
The images sent from the probe's camera captured the gradual growth of the asteroid and the rugged surface of the asteroid just before impact.
There is no risk that the targeted asteroid will actually collide with the earth, and the research team will conduct a detailed analysis of how the asteroid's orbit has changed in the future.
According to NASA and other sources, no asteroids that are large enough to cause major damage to the earth within the next 100 years have been found so far, but NASA is working to find celestial bodies such as asteroids in the future. We aim to develop technology to prevent collisions.
Ralph Semmel, director of the Applied Physics Laboratory at Johns Hopkins University, who participated in the experiment, said at a press conference, ``We were able to demonstrate for the first time an innovative technology for defending the earth from collisions with celestial bodies.'' .
