I dag er overfladen for kold og t\u00f8r til at kunne rumme liv. Nogle forskere mener dog, at der stadig kan findes simple livsformer, s\u00e5som bakterier, dybt nede under jorden.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2003\/03\/Configuration_of_the_ExoMars_rover2\" 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\/2003\/03\/configuration_of_the_exomars_rover2\/17874481-2-eng-GB\/Configuration_of_the_ExoMars_rover.jpg\" alt=\"Configuration of the ExoMars rover\"><figcaption>Konfiguration af ExoMars-roveren<\/figcaption><\/figure>\n<p>Om et par \u00e5r planl\u00e6gger ESA at sende en rover ud for at lede efter liv p\u00e5 Mars.
