La NASA vient d\u2019annoncer que son premier test d'un syst\u00e8me potentiel de d\u00e9fense plan\u00e9taire a \u00e9t\u00e9 un succ\u00e8s notable. Gr\u00e2ce \u00e0 la mission DART, l\u2019agence spatiale a \u00e9t\u00e9 en mesure de d\u00e9vier la trajectoire d\u2019un ast\u00e9ro\u00efde.<\/strong><\/p>\n

La NASA a c\u00e9l\u00e9br\u00e9 mardi le succ\u00e8s d'une mission visant \u00e0 d\u00e9vier un ast\u00e9ro\u00efde lointain<\/strong>, dans le cadre d'un test qu\u2019on pourrait croire tir\u00e9 d\u2019un film de science-fiction sur la capacit\u00e9 de l'humanit\u00e9 \u00e0 emp\u00eacher un objet cosmique de d\u00e9vaster la vie sur Terre<\/strong>. L'impacteur DART (Double Asteroid Redirection Test), de la taille d'un r\u00e9frig\u00e9rateur, s'est d\u00e9lib\u00e9r\u00e9ment \u00e9cras\u00e9 sur l'ast\u00e9ro\u00efde lunaire Dimorphos le 26 septembre, le poussant sur une orbite plus petite et plus rapide autour de son grand fr\u00e8re Didymos, a annonc\u00e9 Bill Nelson, chef de la NASA.<\/p>\n

Il a fallu plusieurs nuits cons\u00e9cutives d'observation au t\u00e9lescope depuis le Chili et l'Afrique du Sud pour d\u00e9terminer dans quelle mesure l'impact a modifi\u00e9 la trajectoire de l'ast\u00e9ro\u00efde. L'ast\u00e9ro\u00efde en question ne repr\u00e9sentait en aucun cas une menace pour la Terre<\/strong>, il s'agissait simplement d'un test.<\/p>\n
