To lahko danes ugotovimo, saj na Marsu obstajajo ogromne izsu\u0161ene doline, ki so jih razli\u010dne vesoljske sonde \u017ee ve\u010dkrat fotografirale. Poleg tega so tam \u0161tevilni pristajalni moduli in raziskovalni roveri odkrili starodavne minerale, ki se lahko oblikujejo le v teko\u010di vodi.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"5333\" data-credit=\"Copyright Context map: NASA\/Viking; THEMIS background: NASA\/JPL-Caltech\/Arizona State University; MARSIS data: ESA\/NASA\/JPL\/ASI\/Univ.

Podnebje na Marsu se je s\u010dasoma spremenilo in \u2013 \u010deprav je sonda Mars Express \u017ee prej zaznala zamrznjeno vodo na polarnih kapah Rde\u010dega planeta \u2013 je teko\u010da voda danes na povr\u0161ini Marsa nepredstavljiva. Zato so se znanstveniki odlo\u010dili raziskati marsovsko podzemlje! Za to so uporabili instrument MARSIS na sondi Mars Express, napreden marsovski radar, ki omogo\u010da sondiranje podpovr\u0161ja in ionosfere Rde\u010dega planeta. MARSIS je \u00abradar za prodiranje v tla\u00bb, kar pomeni, da lahko iz orbite po\u0161ilja radarske impulze na povr\u0161ino Marsa. Z bele\u017eenjem trajanja in intenzivnosti odbitih valov, ki se vra\u010dajo k oddajniku v orbiti, lahko znanstvene ekipe posku\u0161ajo razumeti, kaj se nahaja pod povr\u0161ino. To je precej domiselno!<\/p>\n<p>\u0160tudija, ki temelji na podatkih, zbranih s sistemom MARSIS, je omogo\u010dila dolgo pri\u010dakovano odkritje. Ju\u017ena polarna kapica Marsa vsebuje \u0161tevilne plasti ledu in prahu, globoke 1,5 km, na obmo\u010dju, dolgem pribli\u017eno 200 km. Pod temi plastmi usedlin je pozornost znanstvenikov pritegnil posebej svetel radarski odboj, dolg pribli\u017eno 20 km. Znanstveniki menijo, da bi lahko \u0161lo za veliko jezero teko\u010de vode!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"ESA\/DLR\/FU Berlin, CC BY-SA 3.0 IGO\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/08\/Perspective_view_of_Libya_Montes\" 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\/2018\/08\/perspective_view_of_libya_montes\/17894240-2-eng-GB\/Perspective_view_of_Libya_Montes.jpg\" alt=\"Perspective view of Libya Montes\"><figcaption>Pogled na Libya Montes iz perspektive<\/figcaption><\/figure>\n<p>Na Zemlji se nekatere oblike mikrobnega \u017eivljenja razvijajo v vodnih \u017eepih, kjer razmere niso primerne za \u010dlove\u0161ko \u017eivljenje.
