Podnebje na Marsu se je spremenilo in \u2013 \u010deprav je sonda Mars Express \u017ee prej pokazala, da na polih planeta le\u017ei zamrznjena voda \u2013 teko\u010da voda danes na povr\u0161ini ne more obstajati. Zato so se znanstveniki odlo\u010dili, da bodo pogledali pod zemljo! Uporabili so posebno napravo MARSIS na sondi Mars Express (<b>M<\/b>ars <b>A<\/b>napredno <b>R<\/b>adar za <b>S<\/b>podpovr\u0161je in <b>I<\/b>onosfera <b>S<\/b>(zvo\u010dni) instrument. MARSIS je \u201cradar za prodiranje v tla\u201d. To pomeni, da iz orbite po\u0161ilja radarske impulze proti povr\u0161ini Marsa. Z merjenjem \u010dasa, ki ga impulzi potrebujejo za odboj nazaj, in njihove mo\u010di lahko znanstveniki ugotovijo, kak\u0161ne so razmere pod povr\u0161ino. Pametno!<\/p>\n<p>Raziskava z uporabo instrumenta MARSIS je odkrila tisto, kar so znanstveniki iskali. Ju\u017eni polarni predel Marsa je v preu\u010devanem obmo\u010dju \u0161irine 200 km sestavljen iz \u0161tevilnih plasti ledu in prahu, ki segajo do globine pribli\u017eno 1,5 km. Pod temi plastovitimi usedlinami so odkrili posebej svetel radarski odboj, \u0161irok 20 km. Znanstveniki menijo, da gre 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>Nekatere oblike mikrobnega \u017eivljenja na Zemlji \u017eivijo v vodnih \u017eepih, kjer vladajo razmere, v katerih ljudje ne bi mogli pre\u017eiveti, zato se poraja pomembno vpra\u0161anje: ali v tej marsovski vodi plavajo kak\u0161na drobna bitja?
