La nuit derni\u00e8re, le satellite Sentinelle 1 a \u00e9t\u00e9 lanc\u00e9 par une fus\u00e9e Soyouz depuis le port spatial de l\u2019Europe \u00e0 Kourou, en Guyane fran\u00e7aise.<\/p>\n<\/div>\n

Cet engin de 2,3 tonnes va \u00e9voluer sur une orbite h\u00e9liosynchrone \u00e0 693 kilom\u00e8tres d'altitude. Ce type d\u2019orbite va permettre \u00e0 Sentinelle 1 de survoler la m\u00eame zone terrestre chaque jour \u00e0 un horaire quasi identique.<\/p>\n

Ce lancement marque le d\u00e9but d\u2019une nouvelle \u00e8re : il contribuera \u00e0 \u00e9crire le premier chapitre d\u2019une s\u00e9rie de cinq missions qui seront au c\u0153ur du programme europ\u00e9en Copernicus de surveillance de la Terre. L'ambitieux programme Copernicus nous transmettra des donn\u00e9es d\u00e9taill\u00e9es sur la Terre, l\u2019atmosph\u00e8re et les oc\u00e9ans. Ces pr\u00e9cieuses donn\u00e9es permettront aux d\u00e9cideurs politiques et aux autorit\u00e9s comp\u00e9tentes de prendre des d\u00e9cisions mieux inform\u00e9es en mati\u00e8re d\u2019environnement et de s\u00e9curit\u00e9.<\/p>\n

Cette premi\u00e8re mission sera compos\u00e9e d\u2019une constellation de deux satellites, Sentinelle 1A et Sentinelle 1B, qui captureront en quasi temps r\u00e9el, par tous les types de temps et de jour comme de nuit, des images pr\u00e9cises des surfaces terrestres et oc\u00e9aniques de l\u2019Europe, du Canada et des r\u00e9gions polaires.<\/p>\n

La mission commencera de mani\u00e8re effective d\u2019ici environ trois mois, apr\u00e8s une phase de mise en service permettant de v\u00e9rifier et de calibrer l\u2019ensemble des instruments. Les donn\u00e9es r\u00e9colt\u00e9es par les satellites Sentinelle seront accessibles gratuitement.<\/p>","protected":false},"excerpt":{"rendered":"
