Mars Expressin uusissa kuvissa n\u00e4kyy vuorijono, jota emme ole aiemmin n\u00e4hneet. Vuoret sijaitsevat alueella, jossa tutkatutkimusten perusteella maaper\u00e4n alla piilee suuria m\u00e4\u00e4ri\u00e4 vesij\u00e4\u00e4t\u00e4, joka voisi olla t\u00e4rke\u00e4 vesil\u00e4hde tuleville astronautille.<\/p>\n<\/div>\n

Vuorijonoa kutsutaan nimell\u00e4 Phlegra Montes, ja se ulottuu tulivuorialueen koillisosasta pohjoisen alankomaiden suuntaan. Vuoret itsess\u00e4\u00e4n eiv\u00e4t todenn\u00e4k\u00f6isesti ole tulivuoriper\u00e4isi\u00e4, vaan ne ovat syntyneet muinaisten tektonisten voimien vaikutuksesta, jotka puristivat maankuoren eri osia toisiaan vasten.<\/p>\n

ESA:n Mars Express -luotaimen korkean resoluution kameralla otetut uudet kuvat antavat meille mahdollisuuden tarkastella vuoria paljon tarkemmin kuin aiemmin, ja ne osoittavat, ett\u00e4 l\u00e4hes jokaista vuorta ymp\u00e4r\u00f6i \u2018lobate debris aprons\u2019 eli kaarevia kivimurska-alueita, joita l\u00f6ytyy t\u00e4llaisten jyrk\u00e4nteiden juurelta.<\/p>\n

Aikaisemmissa tutkimuksissa on havaittu, ett\u00e4 n\u00e4m\u00e4 kivet n\u00e4ytt\u00e4v\u00e4t liikkuneen vuorenrinteit\u00e4 alasp\u00e4in ajan my\u00f6t\u00e4 ja ett\u00e4 ne muistuttavat maapallon j\u00e4\u00e4tik\u00f6ilt\u00e4 l\u00f6ytyvi\u00e4 kiviaineksia. T\u00e4m\u00e4n perusteella tutkijat arvelevat, ett\u00e4 Marsin pinnan alla saattaisi olla hautautuneita j\u00e4\u00e4tik\u00f6it\u00e4.<\/p>\n

Lis\u00e4\u00e4 todisteita melko \u00e4skett\u00e4isest\u00e4 j\u00e4\u00e4kaudesta l\u00f6ytyy alueen t\u00f6rm\u00e4yskraattereiden sis\u00e4lt\u00e4. Harjanteiden sarjan uskotaan muodostuneen, kun muinaiset kraatterit t\u00e4yttyiv\u00e4t lumella. Ajan my\u00f6t\u00e4 lumi tiivistyi ja muodosti j\u00e4\u00e4tik\u00f6it\u00e4, jotka sitten veistiv\u00e4t kraatterien pohjat.<\/p>\n

Kaikki n\u00e4m\u00e4 seikat saavat tutkijat ajattelemaan, ett\u00e4 Phlegra Montesin pinnan alla voisi olla suuria m\u00e4\u00e4ri\u00e4 vesij\u00e4\u00e4t\u00e4. Jos t\u00e4m\u00e4 osoittautuu totta, n\u00e4m\u00e4 j\u00e4\u00e4kent\u00e4t voisivat tarjota tuleville astronautille t\u00e4rke\u00e4n vesil\u00e4hteen Punaisella planeetalla.<\/p>","protected":false},"excerpt":{"rendered":"
