ExoMars Rover vil have to hovedopgaver: at udforske omr\u00e5det lige under Mars\u2019 overflade og at lede efter liv. Missionsplanl\u00e6ggerne har n\u00f8je studeret kort over Mars for at finde det bedste sted at lande robotten. Nu er der kun to muligheder tilbage!<\/p>\n<\/div>\n<p>Det er meget sv\u00e6rt at v\u00e6lge et landingssted. Det skal ligge i lav h\u00f8jde og ikke p\u00e5 toppen af et bjerg eller en vulkan. Det er for at give landingsfart\u00f8jet s\u00e5 meget tid som muligt til at falde gennem den tynde marsatmosf\u00e6re, s\u00e5 faldsk\u00e6rmene kan bremse det, inden det n\u00e5r jorden. Desuden b\u00f8r landingsstedet ikke have stejle skr\u00e5ninger eller store klipper, da disse kan g\u00f8re landingen endnu farligere.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1200\" data-credit=\"ESA\/DLR\/FU Berlin &amp; NASA MGS MOLA Science Team\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/04\/Oxia_Planum\" 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\/2017\/04\/oxia_planum\/17902789-2-eng-GB\/Oxia_Planum.jpg\" alt=\"Oxia Planum\"><figcaption>Oxia Planum<\/figcaption><\/figure>\n<p>Et omr\u00e5de p\u00e5 Mars kaldet Oxia Planum ser meget lovende ud og er blevet udvalgt som et af de mulige landingssteder.
