1986. aasta m\u00e4rtsis lendas ESA kosmoselaev Giotto Halley komeedi tuumast 600 km kaugusele. See saatis tagasi esimesed l\u00e4hiv\u00f5tted komeedi j\u00e4isest s\u00fcdamest. N\u00fc\u00fcd on teine ESA kosmoselaev nimega \u201eRosetta\u201c teel komeedi poole. \u201eRosetta\u201c on k\u00f5ige keerukam kosmosemissioon, mida Euroopa on kunagi l\u00e4bi viinud.<\/p>\n<\/div>\n

3-tonnine kosmoselaev kannab pardal 11 katset ja maandumismoodulit, millel on veel 9 katset. Selle energiaallikaks on kaks hiiglaslikku p\u00e4ikesepaneeli, m\u00f5lemad 14 meetri pikkused.<\/p>\n

2. m\u00e4rtsil 2004. aastal teele saadetud Rosetta j\u00f5uab komeedini T\u0161\u00fcrjumov-Gerasimenko 10 aasta p\u00e4rast. Selle kaudne marsruut h\u00f5lmab kolme m\u00f6\u00f6dalendu Maa ja \u00fche Marsi juurest. Rosetta liigub ka sisse ja v\u00e4lja Marsi ja Jupiteri vahel asuvast peamisest asteroidi v\u00f6\u00f6st. See v\u00f5imaldab tal teha l\u00e4hiv\u00f5tteid kahest asteroidist, Steinsist ja Lutetia'st.<\/p>\n

Komeedi l\u00e4hedale j\u00f5udes aeglustab Rosetta oma liikumist ja muudab trajektoori nii, et satub orbiidile vaid m\u00f5ne kilomeetri k\u00f5rgusele tahke tuuma kohal.<\/p>\n

Kui komeet on kaardistatud, vabastab Rosetta oma maandumismooduli (nimega Philae). See kinnitub komeedi tuuma k\u00fclge ja saadab tagasi esimesed pildid komeedi pinnalt.<\/p>\n

Seal \u00fcleval j\u00e4lgib orbiter komeeti, kui see kihutab P\u00e4ikeses\u00fcsteemi sisemise osa suunas. Selle 18 kuu pikkuse j\u00e4lituse jooksul muutuvad komeedi j\u00e4\u00e4d gaasiks, paisates kosmosesse materjalijugasid. Rosetta n\u00e4itab meile esimest korda neid dramaatilisi muutusi, mis toimuvad, kui P\u00e4ike soojendab seda kosmoses asuvat j\u00e4\u00e4m\u00e4ge.<\/p>","protected":false},"excerpt":{"rendered":"
