13 listopada stary przyjaciel powr\u00f3ci\u0142 do domu na kr\u00f3tk\u0105 wizyt\u0119. 44 miesi\u0105ce po wystrzeleniu z Kourou w Gujanie Francuskiej sonda kosmiczna \u201eRosetta\u201d nale\u017c\u0105ca do ESA po raz drugi przelecia\u0142a obok Ziemi. Europejski \u0142owca komet przelecia\u0142 ju\u017c nieco ponad 3 miliardy km, ale przed dotarciem do celu \u2013 komety 67\/P Churyumov-Gerasimenko \u2013 w 2014 roku musi pokona\u0107 jeszcze kolejne 4 miliardy km.<\/p>\n<\/div>\n

Sonda Rosetta porusza si\u0119 po wewn\u0119trznej cz\u0119\u015bci Uk\u0142adu S\u0142onecznego niczym kula bilardowa, nabieraj\u0105c pr\u0119dko\u015bci i zmieniaj\u0105c trajektori\u0119 podczas bliskich spotka\u0144 z Ziemi\u0105 i Marsem. Ten najnowszy kamie\u0144 milowy w tej epickiej podr\u00f3\u017cy by\u0142 trzecim z czterech zaplanowanych dla sondy Rosetta manewr\u00f3w wykorzystuj\u0105cych grawitacj\u0119 planet.<\/p>\n

Po precyzyjnym skorygowaniu orbity poprzez 42-sekundowe uruchomienie silnik\u00f3w manewrowych 18 pa\u017adziernika sonda Rosetta znalaz\u0142a si\u0119 dok\u0142adnie na kursie do przelotu obok Ziemi. O godz. 21:57 czasu \u015brodkowoeuropejskiego (CET) ten wa\u017c\u0105cy 3 tony statek kosmiczny przelecia\u0142 obok Ziemi z pr\u0119dko\u015bci\u0105 45 000 km\/h (12,5 km\/s). Przelatuj\u0105c nad Oceanem Spokojnym, na po\u0142udniowy zach\u00f3d od Chile, sonda Rosetta znajdowa\u0142a si\u0119 zaledwie 5 295 km nad powierzchni\u0105 Ziemi.<\/p>\n

W pobli\u017cu punktu najwi\u0119kszego zbli\u017cenia sonda Rosetta dok\u0142adnie przyjrza\u0142a si\u0119 Ziemi, przeprowadzaj\u0105c obserwacje jej atmosfery i magnetosfery, wykonuj\u0105c zdj\u0119cia obszar\u00f3w miejskich oraz poszukuj\u0105c meteor\u00f3w z kosmosu. Nast\u0119pnie, na trasie powrotnej, rozpocz\u0119\u0142a seri\u0119 obserwacji uk\u0142adu Ziemia\u2013Ksi\u0119\u017cyc.<\/p>\n

Sonda kosmiczna zostanie teraz wyrzucona w kierunku zewn\u0119trznej cz\u0119\u015bci Uk\u0142adu S\u0142onecznego, po czym w listopadzie 2009 roku powr\u00f3ci na Ziemi\u0119 po raz ostatni. Zanim to jednak nast\u0105pi, podczas przelotu przez pas asteroid Rosetta wykorzysta okazj\u0119, by we wrze\u015bniu 2008 roku zbada\u0107 asteroid\u0119 Steins z bliska.<\/p>","protected":false},"excerpt":{"rendered":"
