La mission Envisat a pris fin apr\u00e8s 10 ann\u00e9es de service.<\/p>\n<\/div>\n

Les communications avec le satellite ont \u00e9t\u00e9 interrompues le 8 avril 2012. Depuis ce jour, les ing\u00e9nieurs n'ont pas r\u00e9ussi \u00e0 r\u00e9tablir le contact avec Envisat.<\/p>\n

Toute l\u2019\u00e9quipe Envisat cherche \u00e0 \u00e9claircir le myst\u00e8re de cette situation gr\u00e2ce aux donn\u00e9es transmises par les radars terrestres et par Pl\u00e9iades, la nouvelle mission fran\u00e7aise d\u2019observation de la Terre. Pendant encore deux mois, les ing\u00e9nieurs feront tout leur possible pour r\u00e9tablir le contact avec Envisat.<\/p>\n

Depuis 2002, Envisat et ses 10 instruments nous ont fourni de nombreuses informations sur notre plan\u00e8te. Cette mission nous a permis d\u2019observer la r\u00e9duction de la couche de glace dans l\u2019oc\u00e9an Arctique, l\u2019augmentation de la pollution atmosph\u00e9rique en Asie et les variations du trou dans la couche d\u2019ozone au-dessus de l\u2019Antarctique.<\/p>\n

Gr\u00e2ce aux images transmises par Envisat, nous avons pu analyser les effets de la d\u00e9forestation et am\u00e9liorer notre compr\u00e9hension des tremblements de terre et de l\u2019activit\u00e9 volcanique.<\/p>\n

La mission Envisat sera regrett\u00e9e par toute la communaut\u00e9 scientifique. Le lancement des satellites Sentinelles, qui prendront sa succession, est d\u00e9sormais d\u2019une importance capitale.<\/p>","protected":false},"excerpt":{"rendered":"
