13. novembril naasis vana s\u00f5ber koju l\u00fchikesele k\u00fclask\u00e4igule. 44 kuud p\u00e4rast starti Kouroust Prantsuse Guajaanast lendas ESA kosmoselaev Rosetta teist korda Maa juurest m\u00f6\u00f6da. Euroopa komeedijahtija on n\u00fc\u00fcdseks l\u00e4binud veidi \u00fcle 3 miljardi km, kuid tal on veel 4 miljardit km teekonda ees, enne kui ta 2014. aastal j\u00f5uab oma sihtkohta, komeedile 67\/P T\u0161\u00fcrjomov-Gerasimenko.<\/p>\n<\/div>\n

Rosetta p\u00f5rkab P\u00e4ikeses\u00fcsteemi sisemuses ringi nagu piljardikuul, kiirendades samal ajal ja muutes oma trajektoori l\u00e4hedal kohtumistel Maa ja Marsiga. See viimane verstapost selles eepilises teekonnas oli kolmas neljast Rosettale kavandatud planeetide l\u00e4hedalt m\u00f6\u00f6dumistest.<\/p>\n

P\u00e4rast seda, kui 18. oktoobril t\u00e4psustati Rosetta orbiiti 42 sekundit kestnud t\u00f5ukurite s\u00fc\u00fctamisega, oli kosmoselaev t\u00e4pselt Maale l\u00e4henemise kursil. Kell 21:57 Kesk-Euroopa aja j\u00e4rgi kihutas 3-tonnine kosmoselaev planeedi m\u00f6\u00f6da kiirusega 45 000 km\/h (12,5 km\/s). Kui Rosetta lendas \u00fcle Vaikse ookeani T\u0161iili edelaosas, oli ta vaid 5 295 km k\u00f5rgusel.<\/p>\n

L\u00e4himale l\u00e4henemise ajal uuris Rosetta p\u00f5hjalikult Maad, tehes vaatlusi selle atmosf\u00e4\u00e4ri ja magnetosf\u00e4\u00e4ri kohta, pildistades linnapiirkondi ning otsides kosmosest tulevad meteoore. Seej\u00e4rel alustas ta tagasiteel Maa-Kuu s\u00fcsteemi vaatlusseeriat.<\/p>\n

Kosmoselaev suunatakse n\u00fc\u00fcd P\u00e4ikeses\u00fcsteemi \u00e4\u00e4realade poole, enne kui see 2009. aasta novembris viimast korda Maale tagasi p\u00f6\u00f6rdub. Enne seda aga, kui Rosetta l\u00e4bib asteroidi v\u00f6\u00f6, kasutab ta 2008. aasta septembris v\u00f5imalust uurida asteroidi Steinsit l\u00e4hedalt.<\/p>","protected":false},"excerpt":{"rendered":"
