According to the impact test process of a sci-fi movie live video broadcast on Monday (September 26), the agency's dual asteroid redirection test (DART) spacecraft successfully hit an asteroid called "Dual Form" at 7:14 pm on Monday ( Singapore Tuesday at 7:14 am) at supersonic speeds and a speed of about 22,530 kilometers per hour.
"double-form" is about 160 meters in diameter (like a football field) and it flies around another asteroid called "Didymos" with a diameter of about 780 meters.

NASA Control Center personnel clapped and hugged each other after learning that the mission was successful. "We are opening a new era for mankind, in which we may have the ability to protect ourselves from dangerous asteroid impacts," said Glaz, director of NASA's Planetary Science Department. "We may have the ability to protect ourselves from dangerous asteroid impacts," said Glaz, director of NASA's Planetary Science Department.

DART spacecraft weighs about 570 kilograms, and its main body size is equivalent to a car. There is an solar panel on both sides that is completely unfolded and is about 8.5 meters long, equipped with a high-resolution camera and an automatic navigation system. It was launched from the Vandenberg Space Force Base in California, USA on November 24, 2021 and flew towards the two asteroids.

, a $330 million project that spent seven years to develop, is NASA's first attempt to move asteroids in space to verify the feasibility of changing the orbit of asteroids through "kinetic energy impactor technology" to protect the earth.
"Double Form" originally flew around the "Twins" every 11 hours and 55 minutes. After being hit by a spacecraft, this time may be shortened by 10 minutes, and the distance between the two asteroids will be slightly closer. But team members of the task said it would take about two months to determine whether the orbit of the hit asteroid had changed.
In the future, European Space Agency will launch the "Hera" mission spacecraft to conduct in-depth research on the impact of this impact on the dual asteroid system. Hera will conduct detailed observations of the two asteroids.
