Un vechi prieten s-a \u00eentors acas\u0103 pentru o vizit\u0103 fulger\u0103toare pe 13 noiembrie. La 44 de luni de la lansarea sa de la Kourou, din Guyana Francez\u0103, sonda spa\u021bial\u0103 Rosetta a Agen\u021biei Spa\u021biale Europene (ESA) a trecut pe l\u00e2ng\u0103 P\u0103m\u00e2nt pentru a doua oar\u0103. Sonda european\u0103 de explorare a cometelor a parcurs p\u00e2n\u0103 acum pu\u021bin peste 3 miliarde de km, dar mai are de parcurs \u00eenc\u0103 4 miliarde de km p\u00e2n\u0103 s\u0103 ajung\u0103 la destina\u021bie, cometa 67\/P Churyumov-Gerasimenko, \u00een 2014.<\/p>\n<\/div>\n

Rosetta se mi\u0219c\u0103 prin partea interioar\u0103 a Sistemului Solar ca o bil\u0103 de biliard, acceler\u00e2nd \u0219i schimb\u00e2ndu-\u0219i traiectoria \u00een timpul apropierilor de P\u0103m\u00e2nt \u0219i Marte. Aceast\u0103 ultim\u0103 etap\u0103 important\u0103 a c\u0103l\u0103toriei epice a marcat a treia dintre cele patru manevre de accelerare planetar\u0103 planificate pentru Rosetta.<\/p>\n

Dup\u0103 ce orbita sa a fost ajustat\u0103 cu precizie printr-o activare de 42 de secunde a propulsoarelor sale, pe 18 octombrie, Rosetta se afla exact pe traiectoria prev\u0103zut\u0103 pentru trecerea pe l\u00e2ng\u0103 P\u0103m\u00e2nt. La ora 21:57 CET, sonda spa\u021bial\u0103 de 3 tone a trecut \u00een vitez\u0103 pe l\u00e2ng\u0103 planet\u0103, cu o vitez\u0103 de 45.000 km\/h (12,5 km\/s). \u00cen timp ce survola Oceanul Pacific, la sud-vest de Chile, Rosetta se afla la doar 5.295 km deasupra solului.<\/p>\n

\u00cen momentul apropierii maxime, sonda Rosetta a examinat cu aten\u021bie P\u0103m\u00e2ntul, efectu\u00e2nd observa\u021bii asupra atmosferei \u0219i magnetosferei sale, realiz\u00e2nd imagini ale zonelor urbane \u0219i c\u0103ut\u00e2nd meteori din spa\u021biu. Apoi a \u00eenceput o serie de observa\u021bii asupra sistemului P\u0103m\u00e2nt-Lun\u0103 pe traiectoria sa de \u00eentoarcere.<\/p>\n

Nava spa\u021bial\u0103 va fi acum propulsat\u0103 c\u0103tre partea exterioar\u0103 a Sistemului Solar, \u00eenainte de a se \u00eentoarce pe P\u0103m\u00e2nt pentru ultima oar\u0103, \u00een noiembrie 2009. \u00cens\u0103, \u00eenainte de aceasta, \u00een timp ce va traversa centura de asteroizi, Rosetta va profita de ocazie pentru a studia asteroidul Steins de la distan\u021b\u0103 mic\u0103, \u00een septembrie 2008.<\/p>","protected":false},"excerpt":{"rendered":"
