Mit dem Radarecholot MARSIS an Bord des ESA-Orbiters Mars Express k\u00f6nnen sie nun mehrere Kilometer tief durch festes Eis oder Gestein sehen.<\/p>\n<\/div>\n<p>Bislang war es nur m\u00f6glich, die Oberfl\u00e4che eines Planeten zu erforschen. Der einzige Weg, an Informationen \u00fcber die Beschaffenheit unter der Oberfl\u00e4che zu gelangen, bestand darin, auf dem Planeten zu landen und zu graben oder zu bohren. Mit diesen Methoden kam man aber nur etwa einen halben Meter tief und das Ergebnis war nur f\u00fcr eine einzige Stelle auf dem gro\u00dfen Planeten aussagekr\u00e4ftig.<\/p>\n<p>MARSIS, das erste Radarecholot in einer Umlaufbahn um eine andere Welt, hat uns gezeigt, dass man aus dem All unter die Oberfl\u00e4che eines gesamten Planeten blicken kann. Jetzt, da man mehr \u00fcber die F\u00e4higkeiten eines Radarecholots wei\u00df, denkt das MARSIS-Team \u00fcber die Erkundung anderer Objekte im Sonnensystem nach.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"Jason Craig\/JPL\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2008\/04\/Radar_sounding_is_opening_up_a_planet_s_third_dimension2\" 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\/2008\/04\/radar_sounding_is_opening_up_a_planet_s_third_dimension2\/17893129-2-eng-GB\/Radar_sounding_is_opening_up_a_planet_s_third_dimension.jpg\" alt=\"Radar sounding is opening up a planet\u2019s third dimension\"><figcaption>Radarsondierungen erschlie\u00dfen die dritte Dimension eines Planeten<\/figcaption><\/figure>\n<p>Der Jupitermond Europa ist einer der Orte, an dem ein derartiges MARSIS-Experiment zu aufregenden Entdeckungen f\u00fchren k\u00f6nnte.
