After the spacecraft launched as part of the DART mission of the American National Aeronautics and Space Administration (NASA) crashed into the asteroid on September 27, a trail of 10 thousand kilometers was formed. In Chile, astronomers photographed the comet-like trail formed behind the giant asteroid after the collision with the Southern Astrophysical Research Telescope. It is stated that the trace seen in the photo taken 2 days after the collision is expected to take longer.
First Planetary Defense Study
DART, the first experiment to test a "planetary defense method" against near-Earth objects, is being conducted in collaboration with NASA and the Department of Applied Physics at Johns Hopkins University.
NASA's DART spacecraft crashed into the asteroid Dimorphos, 11 million kilometers from Earth, on September 27. The collision, followed by many telescopes, including the James Webb telescope, is expected to pave the way for determining whether avoidance is possible. By detecting whether the asteroid's velocity has changed, it can prevent large asteroids from colliding with Earth.
