ExoMars Rover vil ha to hovedoppgaver: \u00e5 utforske omr\u00e5det like under overflaten p\u00e5 Mars og \u00e5 lete etter liv. Oppdragsplanleggerne har n\u00f8ye studert kart over Mars for \u00e5 finne det beste stedet \u00e5 lande roboten p\u00e5. N\u00e5 er det bare to alternativer igjen!<\/p>\n<\/div>\n<p>Det er sv\u00e6rt vanskelig \u00e5 velge et landingssted. Det m\u00e5 ligge p\u00e5 lavt niv\u00e5, ikke p\u00e5 toppen av et fjell eller en vulkan. Dette er for \u00e5 gi landingsfart\u00f8yet s\u00e5 mye tid som mulig til \u00e5 falle gjennom den tynne atmosf\u00e6ren p\u00e5 Mars, slik at fallskjermene kan bremse det ned f\u00f8r det n\u00e5r bakken. Landingsstedet b\u00f8r heller ikke ha bratte skr\u00e5ninger eller store steiner, da disse kan gj\u00f8re landingen enda 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 kalt Oxia Planum ser sv\u00e6rt lovende ut og er valgt som et av de mulige landingsstedene. Det ligger litt nord for Mars\u2019 ekvator. For rundt 4 milliarder \u00e5r siden var Oxia Planum sv\u00e6rt annerledes enn i dag. Det var elver med vann som str\u00f8mmet ut i enorme sletter. Selv om vannet n\u00e5 for lengst er borte, kan ExoMars-roveren unders\u00f8ke omr\u00e5det og lete etter tegn p\u00e5 liv som kan ha eksistert den gang, samt utforske mineralagene.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1500\" data-credit=\"ESA\/DLR\/FU Berlin, CC BY-SA 3.0 IGO\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/04\/Mawrth_Vallis\" data-licence=\"CC BY-SA 3.0 IGO or 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\/mawrth_vallis\/18248992-2-eng-GB\/Mawrth_Vallis.jpg\" alt=\"Mawrth Vallis\"><figcaption>Mawrth Vallis<\/figcaption><\/figure>\n<p>Noen hundre kilometer unna ligger det andre potensielle landingsstedet, kalt Mawrth Vallis.
