Les satellites sont en mesure d\u2019observer sans rel\u00e2che la totalit\u00e9 du globe terrestre et de nous fournir de nombreuses informations cruciales sur notre plan\u00e8te. Ils permettent, entre autres, de pr\u00e9voir la m\u00e9t\u00e9o et d\u2019\u00e9tudier l\u2019\u00e9volution de l\u2019exploitation des sols ou encore la croissance des villes. De l\u2019espace, nous pouvons aussi observer de nombreux ph\u00e9nom\u00e8nes naturels ou d\u2019origine humaine qui vont des inondations aux incendies de for\u00eats, en passant par la modification de la couverture glaciaire, la hausse du niveau des oc\u00e9ans et la pollution de l\u2019air.<\/p>\n<\/div>\n

L\u2019ESA construit actuellement une s\u00e9rie de satellites baptis\u00e9e Earth Explorer (en fran\u00e7ais, les Explorateurs de la Terre). Chacun de ces satellites sophistiqu\u00e9s est con\u00e7u pour \u00e9tudier de mani\u00e8re approfondie un th\u00e8me sp\u00e9cifique. Ils nous permettront de mieux conna\u00eetre l'atmosph\u00e8re, les organismes vivants, les fleuves, les oc\u00e9ans et les calottes glaciaires, et, m\u00eame, ce qui se passe sous la cro\u00fbte terrestre. Les informations qu\u2019ils nous fourniront nous permettront aussi de mieux comprendre quel est l\u2019impact de l'homme sur son environnement.<\/p>\n

L\u2019ESA a \u00e9galement lanc\u00e9 une s\u00e9rie de missions de surveillance de la Terre baptis\u00e9e Earth Watch. Elle se compose de satellites m\u00e9t\u00e9orologiques qui embarquent des instruments permettant d'observer les nuages et les vents ou encore de mesurer la temp\u00e9rature et la pression de l'air, et qui renvoient des informations sur de nombreuses autres conditions pr\u00e9sentes sur terre, sur mer et dans l'air.<\/p>\n

L\u2019un de ces satellites est MetOp, un satellite m\u00e9t\u00e9orologique qui \u00e9tudie la m\u00e9t\u00e9o et le climat. Il nous renseigne sur l\u2019atmosph\u00e8re, les nuages, la temp\u00e9rature, l\u2019humidit\u00e9, l\u2019ozone et les vents.<\/p>","protected":false},"excerpt":{"rendered":"
