The DART spacecraft, launched by NASA on November 24, 2021, successfully collided with the asteroid Dimorphos, orbiting one another at a distance of 11 million kilometers from Earth, on September 27. The first experiment, conducted in collaboration with NASA and the Johns Hopkins University Department of Applied Physics, aimed at testing a “planetary defense method” against near-Earth objects was broadcast live. In a written statement released by NASA, it was reported that the orbit of the asteroid Dimorphos, which was hit by the launched spacecraft, has changed.
THE CHARACTER OF THE ASTEROID HAS CHANGED IN 32 MINUTES
NASA confirmed that the spacecraft’s impact changed Dimorphos’s orbit around Didymos by 32 minutes, reducing the orbit from 11 hours and 55 minutes to 11 hours and 23 minutes, taking measurements using a range of space telescopes. and terrestrial.
Prior to the collision, NASA had estimated that the minimum successful orbital period change for Dimorphos was 73 seconds or more. Early data shows that DART outperforms this minimum benchmark by more than 25 times.
“EVIDENCE OF HOW SERIOUS NASA IS DEFENDING THE WORLD”
“This mission demonstrates that NASA is trying to be ready for everything the Universe has to offer,” said NASA President Bill Nelson, noting that it demonstrated how serious NASA is to defend the Earth.
Lori Glaze, Director of NASA’s Planetary Science Division, said in a statement, “This achievement is the goal of DART. asteroid This is an important step towards understanding the full impact of “As new data arrives every day, astronomers will be able to better assess whether and how a mission like DART could be used in the future to help protect the Earth from collision. with an asteroid “.
FIRST EXPERIMENT OF DEFENSE OF THE PLANET
NASA launched the DART mission in November 2021 to determine if it was possible to prevent large asteroids from hitting Earth. Launched as part of the mission, the spacecraft crashed into an asteroid called Dimorphos, 11 million kilometers from Earth, at around 02:15 CEST on September 27. DART is the first experiment to test a method of planetary defense against objects close to the Earth. (UAV)
