It looks like a script in the style of Armageddon, the 1998 blockbuster in which Bruce Willis saves the Earth from the impact of an asteroid the size of Texas: NASA is working on a serious plan to defend the planet from asteroids with which it could enter collision. But this is not a movie, it gets serious as Nancy Chabot, coordinator of the Dart project explains in this video.
The first test of this type will begin on November 24th, with the launch of a spacecraft called Dart, which in English means “dart” but which is actually an acronym for “Double Asteroid Redirection Test”. NASA claims that there are currently no asteroids with a diameter greater than 140 meters capable of hitting the Earth in the next hundred years. However, the US agency already wants to test a method that is able to thwart such a threat, and which may be useful in the future.
