ExoMars Rover kommer att ha tv\u00e5 huvuduppgifter: att utforska omr\u00e5det strax under Mars yta och att s\u00f6ka efter liv. Uppdragets planerare har noggrant studerat kartor \u00f6ver Mars f\u00f6r att best\u00e4mma den b\u00e4sta platsen att landa roboten p\u00e5.

Detta f\u00f6r att landaren ska f\u00e5 s\u00e5 mycket tid som m\u00f6jligt att falla genom den tunna marsatmosf\u00e4ren, s\u00e5 att fallsk\u00e4rmarna hinner bromsa upp den innan den n\u00e5r marken. Landningsplatsen b\u00f6r dessutom inte ha n\u00e5gra branta sluttningar eller stora stenar, eftersom dessa skulle kunna g\u00f6ra landningen \u00e4nnu farligare.<\/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>Ett omr\u00e5de p\u00e5 Mars som kallas Oxia Planum ser mycket lovande ut och har valts ut som en av de m\u00f6jliga landningsplatserna.
