Njegovi senzorji so zaznali nekaj, kar je operaterje na Zemlji zelo navdu\u0161ilo: plin, imenovan metan. Na Zemlji imamo veliko metana. Nastaja lahko v geolo\u0161kih procesih in ga proizvajajo tudi \u017eiva bitja.\u00a0<\/p>\n<\/div>\n<p>V znanosti velja, da so raziskave toliko bolj\u0161e, kolikor ve\u010d podatkov o ne\u010dem zberemo. Zato je skupina znanstvenikov preu\u010devala podatke, ki jih je zbral satelit Mars Express agencije ESA, ki je v tistem \u010dasu kro\u017eil okoli Marsa. Ugotovili so, da je tudi Mars Express zaznal metan!\u00a0<\/p>\n<p>Kaj bi torej lahko povzro\u010dilo nastanek metana na Marsu? Metan se zelo hitro razgradi, ko je izpostavljen celo redki marsovski atmosferi, kar pomeni, da se je plin, ki sta ga zaznala Curiosity in Mars Express, moral nastati ali sprostiti \u0161ele pred kratkim. Ena od mo\u017enosti je, da je metan nastal pred milijoni ali celo milijardami let. Morda je bil ves ta \u010das ujet pod zemljo, dokler mu ni uspelo priti na povr\u0161je, kjer so ga zaznali na\u0161i robotski raziskovalci.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"5333\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/04\/Comparing_the_atmospheres_of_Mars_and_Earth\" 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\/2018\/04\/comparing_the_atmospheres_of_mars_and_earth\/17444033-1-eng-GB\/Comparing_the_atmospheres_of_Mars_and_Earth.jpg\" alt=\"Comparing the atmospheres of Mars and Earth\"><figcaption>Primerjava ozra\u010dij Marsa in Zemlje<\/figcaption><\/figure>\n<p>Druga mo\u017enost je, da bi metan lahko proizvajale drobne \u017eivljenjske oblike na Marsu, pri \u010demer bi metan nastajal kot odpadni produkt. To je zanimiva mo\u017enost, vendar bi bilo treba zbrati ve\u010d dokazov, preden bi lahko pri\u0161li do tega zaklju\u010dka!\u00a0<\/p>\n<p>Znanstveniki trenutno dajejo prednost geolo\u0161kim razlagam pred biolo\u0161kimi. Metan bi se lahko spro\u0161\u010dal iz kamnin po vsem Marsu, vsaki\u010d v majhnih koli\u010dinah. Na Marsu je tudi veliko ledu, v katerem bi se lahko zadr\u017eeval metan. Ko se led stopi ali razpo\u010di, bi se plin lahko izpu\u0161\u010dal v atmosfero.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3638\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2019\/04\/How_to_create_and_destroy_methane_at_Mars\" 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\/2019\/04\/how_to_create_and_destroy_methane_at_mars\/19329127-1-eng-GB\/How_to_create_and_destroy_methane_at_Mars.jpg\" alt=\"How to create and destroy methane at Mars\"><figcaption>Kako nastaja in se razgrajuje metan na Marsu<\/figcaption><\/figure>\n<p>Naslednji korak v tej raziskavi je pregled ve\u010d podatkov s satelitov Mars Express, da bi na\u0161li druge primere, ko bi bilo mogo\u010de zaznati metan.
