Cassini-Huygensi missioon, milles osalesid ESA, NASA ja Itaalia Kosmoseagentuur, on muutnud paljusid meie arusaamu Saturni s\u00fcsteemist. Missioon, mis startis Floridast 1997. aasta oktoobris, j\u00f5udis Saturnini peaaegu seitsme aasta jooksul, l\u00e4bides ligi 3,5 miljardit kilomeetrit. 5,6-tonnine kosmoselaev koosnes kahest osast \u2013 Cassini orbitaalsondist ja Huygensi sondist.<\/p>\n<\/div>\n

Cassini on esimene kosmoselaev, mis tiirleb Saturni \u00fcmber. Laeval on 12 teaduseksperimenti. Alates 1. juulil 2004. aastal Saturnile j\u00f5udmisest on Cassini saatnud tagasi tohutuid koguseid uut teavet Saturni, selle r\u00f5ngaste, kuude ja magnetv\u00e4lja kohta.<\/p>\n

Algselt nelja-aastaseks missiooniks kavandatud Cassini-Huygens on olnud nii edukas, et seda on pikendatud v\u00e4hemalt 2017. aastani. See on lennanud m\u00f6\u00f6da seitsmest suuremast kaaslasest, sealhulgas hiiglaslikust Titanist, mis on suurem kui planeet Merkuur. Orbiitlaev on Titani juurest m\u00f6\u00f6dunud rohkem kui 70 korda. Lendades kuust 880 km kaugusel, on ta uurinud Titani oran\u017ee pilvi ja l\u00e4mmastikurikast atmosf\u00e4\u00e4ri. Samuti on ta kaardistanud selle pinda pildistava radariga.<\/p>\n

2004. aasta j\u00f5ulup\u00fchal eraldus Huygens Cassinist. Kolm n\u00e4dalat hiljem tungis ta Titani tihedasse atmosf\u00e4\u00e4ri, saades esimese sondiks, mis laskus planeedi kaaslase (v\u00e4lja arvatud meie Kuu) pinnale. Soojuskilbi kaitse all aeglustus sondi kiirus vaid kolme minutiga 18 000 kilomeetrilt tunnis 1400 kilomeetrini tunnis. Varsti p\u00e4rast seda avanes suur langevari. Umbes 160 km k\u00f5rgusel hakkas sond pilte tegema ja atmosf\u00e4\u00e4ri uurima. Rohkem kui kahe tunni jooksul v\u00f5eti Huygensilt vastu andmeid ja salvestati need Cassini pardale, kui see sondi kohal lendas.<\/p>\n

Selle kuue instrumendi poolt saadetud pildid ja muu teave andsid meile esimest korda aimu, milline see oran\u017e kuu tegelikult on. Huygens maandus kuival j\u00f5ep\u00f5hjal, mis oli kaetud v\u00e4ikeste j\u00e4iste r\u00e4ndrahnudega.<\/p>","protected":false},"excerpt":{"rendered":"
