Egy r\u00e9gi bar\u00e1tunk november 13-\u00e1n r\u00f6vid l\u00e1togat\u00e1sra t\u00e9rt haza. 44 h\u00f3nappal a francia Guyana-i Kourou-b\u00f3l val\u00f3 ind\u00edt\u00e1sa ut\u00e1n az ESA Rosetta \u0171rszond\u00e1ja m\u00e1sodszor is elhaladt a F\u00f6ld mellett. Eur\u00f3pa \u00fcst\u00f6k\u00f6svad\u00e1sza eddig valamivel t\u00f6bb mint 3 milli\u00e1rd km-t tett meg, de m\u00e9g 4 milli\u00e1rd km-t kell megtennie, miel\u0151tt 2014-ben meg\u00e9rkezik c\u00e9lj\u00e1hoz, a 67\/P Churyumov\u2013Gerasimenko \u00fcst\u00f6k\u00f6shez.<\/p>\n<\/div>\n

A Rosetta \u00fagy pattog a Naprendszer bels\u0151 r\u00e9sz\u00e9n, mint egy bili\u00e1rdgoly\u00f3, mik\u00f6zben a F\u00f6lddel \u00e9s a Marssal val\u00f3 k\u00f6zeli tal\u00e1lkoz\u00e1sok sor\u00e1n sebess\u00e9get nyer \u00e9s p\u00e1ly\u00e1j\u00e1t v\u00e1ltoztatja. Ez a hatalmas utaz\u00e1s leg\u00fajabb m\u00e9rf\u00f6ldk\u00f6ve a Rosetta sz\u00e1m\u00e1ra tervezett n\u00e9gy bolyg\u00f3 k\u00f6r\u00fcli elhalad\u00e1s k\u00f6z\u00fcl a harmadikat jelentette.<\/p>\n

Miut\u00e1n okt\u00f3ber 18-\u00e1n a hajt\u00f3m\u0171veinek 42 m\u00e1sodperces bekapcsol\u00e1s\u00e1val finomhangolt\u00e1k a p\u00e1ly\u00e1j\u00e1t, a Rosetta pontosan a F\u00f6ld melletti elhalad\u00e1sra ir\u00e1nyult. K\u00f6z\u00e9p-eur\u00f3pai id\u0151 szerint 21:57-kor a 3 tonn\u00e1s \u0171reszk\u00f6z 45 000 km\/h (12,5 km\/s) sebess\u00e9ggel sz\u00e1guldott el a bolyg\u00f3 mellett. Amikor Chile d\u00e9lnyugati r\u00e9sz\u00e9n\u00e9l a Csendes-\u00f3ce\u00e1n felett elrep\u00fclt, a Rosetta mind\u00f6ssze 5 295 km-re volt a F\u00f6ld felsz\u00edn\u00e9t\u0151l.<\/p>\n

A legk\u00f6zelebbi pont k\u00f6zel\u00e9ben a Rosetta alaposan megvizsg\u00e1lta a F\u00f6ldet: megfigyelte annak l\u00e9gk\u00f6r\u00e9t \u00e9s m\u00e1gneses ter\u00e9t, felv\u00e9teleket k\u00e9sz\u00edtett v\u00e1rosi ter\u00fcletekr\u0151l, \u00e9s az \u0171rb\u0151l \u00e9rkez\u0151 meteorokat kereste. Ezut\u00e1n a F\u00f6ld\u2013Hold-rendszer megfigyel\u00e9s\u00e9nek sorozat\u00e1ba kezdett a visszat\u00e9r\u0151 p\u00e1ly\u00e1j\u00e1n.<\/p>\n

Az \u0171reszk\u00f6zt most a Naprendszer k\u00fcls\u0151 r\u00e9sz\u00e9be katapult\u00e1lj\u00e1k, miel\u0151tt 2009 november\u00e9ben utolj\u00e1ra visszat\u00e9rne a F\u00f6ldre. De m\u00e9g azel\u0151tt, amikor \u00e1thalad az aszteroid\u00f6vezeten, a Rosetta 2008 szeptember\u00e9ben megragadja az alkalmat, hogy k\u00f6zelr\u0151l tanulm\u00e1nyozza a Steins aszteroid\u00e1t.<\/p>","protected":false},"excerpt":{"rendered":"
