Dangerous operation on November 24: NASA will try to deviate the trajectory of the double asteroid

We’re not in a science fiction movie with Bruce Willis, but in reality. 24, NASA will send a rocket to a double asteroid to try to deviate from its trajectory. At least that’s what he hopes.

The Dart mission will take off on a SpaceX Falcon 9 rocket on November 23. It was only 10 months later that the rocket hit its dual targets, Didymos and Dimorphos (a moon that spins around it), 780 and 160 meters tall, respectively.

The rocket will hit Dimorphos at a speed of about 24,000 km/h. A satellite that accompanies the rocket would then be responsible for studying the reaction of the two celestial bodies. Observations from terrestrial telescopes showed that Dimorphos orbited Didymos in 11 hours 55 minutes. The period will be measured again with these telescopes.

These observations will allow scientists to know what force we would have to use if such an asteroid struck Earth. Isn’t it a dangerous experience to steer an asteroid out of its path? “It’s a very safe experience,” said Andy Cheng of Johns Hopkins University, who is collaborating with NASA on this mission. The two objects are located about 11 million kilometers apart, and then the effect on the gravitational relationship between Didymos and the Sun would be only minimal and not even quantifiable.

The total cost of the mission is estimated at $330 million.


When was the last time an asteroid hit Earth? We’re bombarded with all kinds of objects, NASA explains. But our atmosphere often breaks down before impact. The last time a celestial body touched Earth was in 2013 in Siberia, but the collision had no real effect. In the long term, this is very complicated to know, because soil erosion doesn’t really allow knowing for sure.

There are an estimated 23,000 near-Earth asteroids. Perhaps the most dangerous of them is the celestial body Bennu of 500 meters in diameter. By 2300, he has a 0.057% chance of hitting us.
