Eurooppalaiset tutkijat haluavat l\u00e4hett\u00e4\u00e4 Mars-m\u00f6nkij\u00e4n etsim\u00e4\u00e4n el\u00e4m\u00e4n merkkej\u00e4 Marsista. T\u00e4m\u00e4 k\u00e4vi ilmi viime viikolla Birminghamissa, Englannissa pidetyn kahden p\u00e4iv\u00e4n mittaisen ESA:n kokouksen j\u00e4lkeen.<\/p>\n<\/div>\n

Mars on kaikista planeetoista eniten Maata muistuttava, ja se on \u2013 Maata lukuun ottamatta \u2013 todenn\u00e4k\u00f6isin paikka, jossa alkeellista el\u00e4m\u00e4\u00e4 voisi esiinty\u00e4. ESA:n Mars Express -kiertoradalta saadut tiedot viittaavat siihen, ett\u00e4 Punainen planeetta oli aikoinaan paljon l\u00e4mpim\u00e4mpi ja kosteampi kuin nyky\u00e4\u00e4n.<\/p>\n

Onko sen j\u00e4\u00e4tyneen pinnan alla nestem\u00e4ist\u00e4 vett\u00e4? Jos on, el\u00e4\u00e4k\u00f6 siell\u00e4 yksinkertaista el\u00e4m\u00e4\u00e4? Saadakseen vastauksen n\u00e4ihin mysteereihin tutkijat haluavat tutkia Marsin pintaa huipputeknisell\u00e4 marsroverilla.<\/p>\n

Ehdotetun avaruuslennon l\u00e4ht\u00f6ajankohta olisi kes\u00e4kuussa 2011. Kahden vuoden matkan j\u00e4lkeen roverin laskeutumista Marsiin pehment\u00e4isiv\u00e4t turvatyynyt ja mahdollisesti jarrutusraketit.<\/p>\n

Yksi sen p\u00e4\u00e4teht\u00e4vist\u00e4 olisi etsi\u00e4 merkkej\u00e4 el\u00e4m\u00e4st\u00e4 \u2013 menneest\u00e4 tai nykyisest\u00e4. M\u00f6nkij\u00e4n hy\u00f6tykuormaan kuuluisi kaasuanalyysikoe, jolla etsitt\u00e4isiin ilmakeh\u00e4st\u00e4 kemiallisia merkkej\u00e4 el\u00e4m\u00e4st\u00e4.<\/p>\n

M\u00f6nkij\u00e4\u00e4n asennettu pora ottaisi kivi- ja maaper\u00e4n\u00e4ytteit\u00e4 2 metrin syvyydest\u00e4. N\u00e4it\u00e4 tutkittaisiin my\u00f6s kaasuanalyysikokeen avulla.<\/p>\n

M\u00f6nkij\u00e4n muut laitteet etsisiv\u00e4t vett\u00e4, tutkisivat maanpinnan alla olevia kalliokerroksia ja mittaisivat Marsin maanj\u00e4ristyksi\u00e4. Niiden avulla tunnistettaisiin my\u00f6s vaarat, jotka saattaisivat uhata tulevia ihmisten suorittamia avaruuslentoja.<\/p>\n

Kun katsotaan pidemm\u00e4lle tulevaisuuteen, tutkijat vahvistivat sitoutuvansa osallistumaan kansainv\u00e4liseen n\u00e4ytteiden palautusmissioon vuonna 2016.<\/p>","protected":false},"excerpt":{"rendered":"
