M\u00e4rz 2002, startete der gr\u00f6\u00dfte je gebaute Erdbeobachtungssatellit vom Weltraumbahnhof Kourou in Franz\u00f6sisch-Guayana. Inzwischen hat dieser Satellit mit dem Namen Envisat und einem Gewicht von acht Tonnen die Erde mehr als 50.000-mal umrundet. Mit seinen zehn hochmodernen, ganz unterschiedlichen Instrumenten \u00fcberwacht er kontinuierlich die Landmassen, Ozeane, Eiskappen und die Atmosph\u00e4re der Erde.<\/p>\n<\/div>\n<p>So verr\u00e4t uns Envisat vieles \u00fcber unseren Planeten, wovon wir ohne ihn nichts w\u00fcssten. Im letzten Sommer zum Beispiel ergaben Radarmessungen, dass die arktische Meereisdecke so weit zur\u00fcckgegangen war wie noch nie zuvor. Andere Instrumente zeigen uns L\u00f6cher in der immer d\u00fcnneren Ozonschicht des Planeten, Schadstoffe \u00fcber gro\u00dfen Industriest\u00e4dten und brennende W\u00e4lder.<\/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>Aber auch den Klimawandel kann man mit Envisat beobachten, die Temperaturen der Land- und Wasserfl\u00e4chen der Erde erfassen, die Eisbedeckung der Meere kartieren und \u00d6lteppiche \u00fcberwachen.<\/p>\n<p>Noch bis mindestens 2013 wird uns der nunmehr 10 Jahre alte Satellit weiterhin wichtige Erdbeobachtungsdaten liefern.
