Le premier de la nouvelle famille de satellites Sentinel d'observation de la Terre de l' ESA a \u00e9t\u00e9 transf\u00e9r\u00e9 au centre spatial europ\u00e9en de Kourou, en Guyane. Apr\u00e8s sept ann\u00e9es de travail pour la conception, l'assemblage et les essais, Sentinel-1A sera lanc\u00e9 \u00e0 bord d'un vaisseau Soyuz le 3 avril 2014.<\/p>\n<\/div>\n

Le satellite p\u00e8sera pas moins de 2,3 tonnes au moment du lancement. Avec ses deux ailes solaires de 10 m\u00e8tres de long et son antenne radar de 12 m\u00e8tres d'envergure, Sentinel-1A ne ressemble pas aux autres satellites. Les ailes solaires et le radar seront pli\u00e9s de mani\u00e8re \u00e0 se loger dans le car\u00e9nage protecteur de la coiffe du lanceur. Une fois le satellite largu\u00e9 dans l\u2019espace, les ailes solaires et le radar se d\u00e9ploieront dans un ordre soigneusement \u00e9tabli, processus qui durera une dizaine d'heures.<\/p>\n

Once it becomes operational, Sentinel-1A\u2019s advanced radar instrument will image Earth’s surface 24 hours a day, seven days a week, regardless of whether it is cloudy or dark.<\/p>\n

Les informations livr\u00e9es par Sentinel-1A serviront \u00e0 de nombreuses applications. Le satellite permettra de cartographier la couverture de la glace de mer de l'Arctique, de rep\u00e9rer les mar\u00e9es noires et de localiser les navires. Il \u00e9tudiera les ressources des for\u00eats, des eaux et des sols et apportera une aide pr\u00e9cieuse pendant les situations de crise. \u00c0 cet \u00e9gard, il est le seul satellite europ\u00e9en sp\u00e9cialement con\u00e7u pour faciliter les secours lors de catastrophes, telles que les inondations et les s\u00e9ismes.<\/p>\n

Le lancement d'un deuxi\u00e8me satellite identique, Sentinel-1, est pr\u00e9vu l'ann\u00e9e prochaine. Ensemble, ces deux satellites poursuivront le long travail d'\u00e9tudes radar assur\u00e9 par ERS-1, ERS-2 et Envisat.<\/p>","protected":false},"excerpt":{"rendered":"
