Selle andurid tuvastasid midagi, mis tekitas Maal asuvates juhtimiskeskustes suurt elevust: gaasi nimega metaan. Maal on metaanit palju. Seda v\u00f5ivad tekitada nii geoloogilised protsessid kui ka elusolendid.\u00a0<\/p>\n<\/div>\n<p>Teaduses kehtib reegel, et mida rohkem andmeid mingi teema kohta kogutakse, seda paremad v\u00f5ivad olla uuringud. Seet\u00f5ttu on teadlaste r\u00fchm uurinud andmeid, mille kogus ESA satelliit \u201eMars Express\u201d, mis tiirles samal ajal Marsi orbiidil. N\u00fc\u00fcd on nad avastanud, et ka \u201eMars Express\u201d tuvastas metaani!\u00a0<\/p>\n<p>Mis v\u00f5is siis Marsi metaani tekitada? Metaan laguneb v\u00e4ga kiiresti, kui see puutub kokku isegi Marsi h\u00f5reda atmosf\u00e4\u00e4riga, mis t\u00e4hendab, et Curiosity ja Mars Expressi poolt avastatud gaas pidi tekkima v\u00f5i vabanema alles v\u00e4ga hiljuti. \u00dcks v\u00f5imalus on, et metaan tekkis miljoneid v\u00f5i isegi miljardeid aastaid tagasi. See v\u00f5is kogu selle aja jooksul olla maa all l\u00f5ksus, kuni see l\u00f5puks suutis pinnale j\u00f5uda, kus meie robotuurijad selle avastasid.<\/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>Marsi ja Maa atmosf\u00e4\u00e4ride v\u00f5rdlus<\/figcaption><\/figure>\n<p>Teine v\u00f5imalus on see, et metaani v\u00f5isid toota Marsi pisikesed elusolendid, kelle jaoks metaan oli j\u00e4\u00e4kprodukt.
