Desde entonces, este ingenio de ocho toneladas, llamado Envisat, ha dado la vuelta a la Tierra m\u00e1s de 50 000 veces. En su recorrido, observa continuamente la atm\u00f3sfera, el suelo, los oc\u00e9anos y las capas de hielo del planeta mediante diez sofisticados instrumentos.<\/p>\n<\/div>\n<p>Gracias a estos instrumentos, ahora sabemos cosas de la Tierra que, de otra forma, hubiera sido imposible saber. Por ejemplo, el verano pasado, un radar de Envisat detect\u00f3 que el grosor de la capa de hielo del \u00c1rtico hab\u00eda descendido a niveles sin precedentes. Otros instrumentos nos han permitido descubrir agujeros en la cada vez m\u00e1s delgada capa de ozono, y observar la atm\u00f3sfera contaminada de las grandes ciudades industriales o la progresiva desaparici\u00f3n de los bosques.<\/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>Envisat tambi\u00e9n nos ayuda a aprender m\u00e1s sobre el cambio clim\u00e1tico, y sobre la temperatura del agua y la tierra.
