Mars oli kunagi soojem ja niiskem kui praegu. ESA kosmosesondi \u201eMars Express\u201c ja teiste kosmosesondide poolt saadetud pildid n\u00e4itavad hiiglaslikke kanaleid, mis meenutavad kuivanud j\u00f5gede s\u00e4ngi. Kuhu vesi kadus?<\/p>\n<\/div>\n

V\u00e4ike osa sellest on talletunud polaarj\u00e4\u00e4katetesse. Osa on p\u00e4\u00e4senud kosmosesse. Kuid suur osa sellest on k\u00fclmunud mulda ja kivimisse.<\/p>\n

On v\u00f5imalik, et elu tekkis Marsil miljardeid aastaid tagasi, kui seal oli soe ja niiske. T\u00e4nap\u00e4eval on planeedi pind eluks liiga k\u00fclm ja kuiv. Siiski arvavad m\u00f5ned teadlased, et s\u00fcgaval maa all v\u00f5ib ikka veel eksisteerida lihtne elu, n\u00e4iteks bakterid.<\/p>\n

M\u00f5ne aasta p\u00e4rast kavatseb ESA saata Marsile marsiroveri, et otsida seal elu. Sellele j\u00e4rgneb missioon, mille k\u00e4igus tuuakse teaduslikuks uurimiseks tagasi kivimeid ja pinnast.<\/p>\n

Peale Marsi v\u00f5ib elu eksisteerida ka Jupiteri m\u00f5nede kuude j\u00e4\u00e4ga kaetud ookeanides. Ka Saturnuse suurim kuu Titan on v\u00e4ga huvitav koht.<\/p>\n

Teadlased arvavad, et Titan on nagu noor Maa \u2013 ainult palju k\u00fclmem. 2005. aasta jaanuaris maandus ESA sond Huygens sellel j\u00e4isel, suduga kaetud kaaslasel. Sealt leiti kuivaid j\u00f5ekaldeid ja j\u00e4rvi, mis on m\u00f5nikord t\u00e4idetud vedela metaaniga.<\/p>","protected":false},"excerpt":{"rendered":"
