Este sat\u00e9lite de oito toneladas, denominado Envisat, j\u00e1 deu mais de 50 000 voltas \u00e0 Terra. Com dez instrumentos sofisticados, observa e monitoriza continuamente a superf\u00edcie terrestre, a atmosfera, os oceanos e as calotas polares.<\/p>\n<\/div>\n<p>Os diversos instrumentos do Envisat permitiram-nos descobrir coisas sobre o nosso planeta que nunca ter\u00edamos sabido sem ele. Por exemplo, no ver\u00e3o passado, um radar do Envisat registou uma cobertura de gelo marinho no \u00c1rtico que atingiu um m\u00ednimo hist\u00f3rico. Outros instrumentos permitiram-nos observar buracos na camada de ozono do planeta, que se est\u00e1 a tornar cada vez mais fina, bem como poluentes sobre as principais cidades industriais e florestas em chamas.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\/EJR-Quartz\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2009\/12\/Envisat_for_Schools_Animation2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2009\/12\/envisat_for_schools_animation2\/17868043-3-eng-GB\/Envisat_for_Schools_Animation.jpg\" alt=\"\"><\/figure>\n<p>O Envisat tamb\u00e9m permite aprofundar os conhecimentos sobre as altera\u00e7\u00f5es clim\u00e1ticas, bem como sobre a temperatura terrestre e mar\u00edtima.
