A Gizmodo besz\u00e1mol\u00f3ja szerint a kutat\u00f3k a marsi k\u00f6r\u00fclm\u00e9nyeket, vagyis a fagypont alatti h\u0151m\u00e9rs\u00e9klet, a szimul\u00e1lt kozmikus sug\u00e1rz\u00e1s, valamint a kisz\u00e1rad\u00e1s hat\u00e1sait tesztelt\u00e9k hat mikroorganizmuson. A kutat\u00f3k arra jutottak, hogy ha volt \u00e9let a Marson, akkor az ugyan nem maradhatott fenn m\u00e1ig a k\u00edm\u00e9letlen k\u00f6r\u00fclm\u00e9nyek miatt, \u00e1m a makromolekul\u00e1k \u00e9s a v\u00edrusok sokkal tov\u00e1bb \u00e9letben maradhattak, mint azt eddig gondolt\u00e1k.<\/p>\n\n\n\n

Michael Daly, a Northwestern Egyetem kutat\u00f3ja szerint mindez meger\u0151s\u00edti, hogy a j\u00f6v\u0151beni kutat\u00e1sok sor\u00e1n kider\u00fclhet, hogy volt-e \u00e9let a v\u00f6r\u00f6s bolyg\u00f3 felsz\u00edn\u00e9n.<\/p>\n\n\n\n

A mikroorganizmusokat k\u00fcl\u00f6nb\u00f6z\u0151 m\u00e9rt\u00e9k\u0171 sug\u00e1rz\u00e1snak tett\u00e9k ki, \u00edgy szimul\u00e1lva a felsz\u00edn \u00e9s a felsz\u00edn alatti \u00e1llapotokat. Az egyik a Deinococcus radiodurans volt, ami rendk\u00edv\u00fcli sz\u00edv\u00f3ss\u00e1g\u00e1r\u00f3l ismert, ez\u00e9rt Conan, a bakt\u00e9rium n\u00e9ven is illetik.<\/p>\n\n\n\n

Az apr\u00f3 \u00e9l\u0151l\u00e9nynek a 140 ezer gray sug\u00e1rz\u00e1st is siker\u00fclt t\u00fal\u00e9lnie, ami nagy ugr\u00e1s a kor\u00e1bbi 25 ezerhez k\u00e9pest. Csak \u00f6sszehasonl\u00edt\u00e1sk\u00e9nt: ha egy ember sok\u00e1ig 5 graynek van kit\u00e9ve, az hal\u00e1los d\u00f3zist jelent.<\/p>\n\n\n\n

A kutat\u00f3k arra jutottak, hogy a felsz\u00ednen n\u00e9h\u00e1ny \u00f3ra alatt elpusztulna, 10 centim\u00e9terrel a marsi felsz\u00edn alatt azonban m\u00e1r 1,5 milli\u00f3, 10 m\u00e9terrel pedig 280 milli\u00f3 \u00e9vvel n\u0151ne a t\u00fal\u00e9l\u00e9si ideje.<\/p>\n\n\n\n

Mivel 2 milli\u00e1rd \u00e9ve nem folyik v\u00edz a Mars felsz\u00edn\u00e9n, \u00edgy val\u00f3sz\u00edn\u0171leg az \u00e9let is kihalt a bolyg\u00f3n, azonban sokkal tov\u00e1bb maradhatott \u00e9letben, mint eddig gondolt\u00e1k. Hogy val\u00f3ban volt-e, az n\u00e9h\u00e1ny \u00e9v m\u00falva der\u00fclhet ki.<\/p>\n\n\n\n
