Africa-Press – Guin\u00e9e. <\/strong><\/span>Une sortie dans l’espace pr\u00e9vue mardi pour r\u00e9parer une antenne d\u00e9fectueuse de la Station spatiale internationale (ISS) a \u00e9t\u00e9 report\u00e9e sine die, a annonc\u00e9 la Nasa, invoquant une \u00ab\u00a0notification de d\u00e9bris\u00a0\u00bb qu’elle a re\u00e7ue du laboratoire de recherche spatiale.<\/p>\n

Deux astronautes am\u00e9ricains devaient effectuer une sortie de de la station spatiale \u00e0 12h10 GMT pour commencer leur travail, une mission consid\u00e9r\u00e9e \u00e0 risque l\u00e9g\u00e8rement \u00e9lev\u00e9 par les responsables de la Nasa en raison des d\u00e9bris engendr\u00e9s par un essai de missile antisatellite russe ce mois-ci.<\/p>\n

L’agence spatiale am\u00e9ricaine n’a pas pr\u00e9cis\u00e9 \u00e0 quel point les d\u00e9bris s’\u00e9taient approch\u00e9s de la station spatiale, en orbite \u00e0 environ 402 km au-dessus de la Terre, ni s’ils \u00e9taient li\u00e9s \u00e0 l’essai russe.<\/p>\n

L’objectif de la sortie est de retirer un ensemble d’antennes de communication radio d\u00e9fectueux, qui a maintenant plus de 20 ans, pour le remplacer par un nouveau \u00e0 l’ext\u00e9rieur de la station spatiale.<\/p>\n

Quatre astronautes sont parvenus \u00e0 la station spatiale le 11 novembre \u00e0 bord d’une capsule Dragon de SpaceX lanc\u00e9e du Centre spatial Kennedy de Cap Canaveral, en Floride, pour rejoindre deux astronautes russes et un autre de la Nasa \u00e0 bord de l’avant-poste.<\/p>\n

Quatre jours plus tard, un essai de missile antisatellite effectu\u00e9 sans avertissement par la Russie a g\u00e9n\u00e9r\u00e9 un champ de d\u00e9bris qui a forc\u00e9 les sept personnes \u00e0 bord de la Station spatiale internationale \u00e0 se r\u00e9fugier dans leurs vaisseaux, selon la Nasa.<\/p>\n

Le nuage de d\u00e9bris r\u00e9siduels provoqu\u00e9 par l’explosion s’est depuis dispers\u00e9, selon Dana Weigel, directrice adjoint du programme de la Station spatiale internationale (ISS) \u00e0 la NASA.<\/p>\n

Mais l’agence spatiale am\u00e9ricaine estime que les fragments restants continuent de poser un risque de fond \u00ab\u00a0l\u00e9g\u00e8rement \u00e9lev\u00e9\u00a0\u00bb pour l’ensemble de la station spatiale, et un risque 7% plus \u00e9lev\u00e9 de perforation des combinaisons des astronautes par rapport \u00e0 avant le test de missile russe, a d\u00e9clar\u00e9 Weigel lundi.<\/p>\n
