Le plus lourd cargo spatial jamais lanc\u00e9 par l\u2019Europe est pr\u00eat \u00e0 d\u00e9coller de la base de Kourou en Guyane fran\u00e7aise. Le second v\u00e9hicule de transfert automatique (ATV) de l\u2019ESA sera lanc\u00e9 le mercredi 16 f\u00e9vrier \u00e0 22 h 50 CET en direction de la Station spatiale internationale (ISS) sur une fus\u00e9e Ariane 5.<\/p>\n<\/div>\n

Il apportera des fournitures essentielles \u00e0 l\u2019\u00e9quipage et rehaussera l\u2019orbite de la Station. Sa mission doit durer trois mois et demi. Apr\u00e8s un vol de huit jours, il atteindra l\u2019\u00e9norme station pour achever son amarrage automatique le 23 f\u00e9vrier.<\/p>\n

L\u2019ATV-2 a \u00e9t\u00e9 baptis\u00e9 \u00ab Johannes Kepler \u00bb en m\u00e9moire du c\u00e9l\u00e8bre astronome allemand du XVIIe si\u00e8cle. Apr\u00e8s le vol de qualification tr\u00e8s r\u00e9ussi du Jules Verne en 2008, il s\u2019agit du premier ATV op\u00e9rationnel. Avec une masse totale de lancement sup\u00e9rieure \u00e0 20 tonnes, il transporte une cargaison de 7 tonnes, dont 4,5 tonnes d\u2019ergols qui lui permettront de contr\u00f4ler la position de l\u2019ISS et de rehausser son orbite de temps \u00e0 autre. La charge utile de l\u2019ATV comprend \u00e9galement pr\u00e8s de 1600 kg de cargaison s\u00e8che, 850 kg d\u2019ergols destin\u00e9 au module russe Zvezda et 100 kg d\u2019oxyg\u00e8ne !<\/p>\n

L\u2019ISS disposant d\u00e9j\u00e0 de suffisamment d\u2019eau potable, cette mission n\u2019en emportera pas. Les r\u00e9servoirs d\u2019eau seront n\u00e9anmoins remplis des d\u00e9chets liquides de la Station avant que l\u2019ATV ne quitte l\u2019ISS en juin. Des sacs d\u2019ordures et des \u00e9quipements qui ne sont plus utilis\u00e9s seront \u00e9galement charg\u00e9s par l\u2019\u00e9quipage. L\u2019ATV proc\u00e9dera alors \u00e0 sa d\u00e9sorbitation au-dessus de l'oc\u00e9an Pacifique avant de se consumer dans l\u2019atmosph\u00e8re.<\/p>\n
