Kui vaatate l\u00e4hikuudel p\u00e4rast pilvitu p\u00e4ikeseloojangut l\u00e4\u00e4ne poole, ei saa te j\u00e4tta m\u00e4rkamata s\u00e4ravat \u201c\u00f5htut\u00e4hte\u201c. Kuid see pimestav vaatepilt ei ole tegelikult t\u00e4ht. See on planeet Veenus \u2013 Euroopa viimase kaugkosmosemissiooni sihtkoht.<\/p>\n<\/div>\n

Venus Express on esimene ESA kosmoselaev, mis hakkab uurima Maa peaaegu t\u00e4pset kaksikut. Laev, mille k\u00e4ivitamine on kavandatud 2005. aasta oktoobris Venemaa \u201eSojuz\u201d raketiga, j\u00f5uab eeldatavasti Veenuse orbiidile 2006. aasta aprillis.<\/p>\n

Kosmoselaev, mis liigub poluste kohal 250\u201366 000 km k\u00f5rgusel, veedab kaks Veenuse aastat (500 Maa p\u00e4eva) Maa l\u00e4hima naaberplaneedi paksu pilvkatte ja atmosf\u00e4\u00e4ri uurimisega.<\/p>\n

P\u00e4ikesest teise planeedi uurimiseks on sinna saadetud \u00fcle 20 Venemaa ja Ameerika kosmoselaeva, kuid paljud saladused on endiselt lahendamata:<\/p>\n

  • \n

    Millised on atmosf\u00e4\u00e4ri temperatuur ja koostis?<\/p>\n<\/li>\n

  • \n

    Kuidas toimub atmosf\u00e4\u00e4ri tsirkulatsioon?<\/p>\n<\/li>\n

  • \n

    Kuidas muutub selle koostis \u00fclevalt alla poole liikudes?<\/p>\n<\/li>\n

  • \n

    Kuidas m\u00f5jutab atmosf\u00e4\u00e4r maapinda?<\/p>\n<\/li>\n

    Kuidas m\u00f5jutab \u00fclemine atmosf\u00e4\u00e4r p\u00e4ikesetuult?<\/p>\n<\/li>\n<\/ul>\n

    Venus Expressi pardal olevad seitse teaduslikku seadet p\u00fc\u00fcavad neid m\u00f5istatusi lahendada.<\/p>\n

    Nagu nimigi viitab, projekteeriti ja ehitati \u201eVenus Express\u201c vaid kolme aastaga \u2013 planeetidevahelise kosmoses\u00f5iduki jaoks on see v\u00e4ga kiire. Sarnaselt ESA edukale \u201eMars Expressi\u201c orbiidilennukile on kosmoses\u00f5iduk kohandatud Veenuse k\u00f5rgemate temperatuuride ja kiirgusega toime tulemiseks. Suurem osa selle m\u00f5\u00f5teriistadest p\u00f5hineb \u201eMars Expressi\u201c ja \u201eRosetta\u201c missioonide jaoks arendatud riistvaral.<\/p>","protected":false},"excerpt":{"rendered":"
