\u00cen martie 1986, sonda spa\u021bial\u0103 Giotto a ESA s-a apropiat la o distan\u021b\u0103 de 600 km de nucleul cometei Halley. Aceasta a transmis primele imagini \u00een prim-plan ale nucleului \u00eenghe\u021bat al unei comete. Acum, o alt\u0103 sond\u0103 spa\u021bial\u0103 a ESA, numit\u0103 Rosetta, se \u00eendreapt\u0103 spre o comet\u0103. Rosetta este cea mai complex\u0103 misiune spa\u021bial\u0103 realizat\u0103 vreodat\u0103 de Europa.<\/p>\n<\/div>\n

Nava spa\u021bial\u0103 de 3 tone transport\u0103 11 experimente \u0219i un modul de aterizare, care con\u021bine alte 9 experimente. Aceasta este alimentat\u0103 de dou\u0103 panouri solare uria\u0219e, fiecare av\u00e2nd o lungime de 14 metri.<\/p>\n

Lansat\u0103 pe 2 martie 2004, sonda Rosetta va avea nevoie de 10 ani pentru a ajunge la cometa Churyumov-Gerasimenko. Traseul ocolitor include trei treceri pe l\u00e2ng\u0103 P\u0103m\u00e2nt \u0219i una pe l\u00e2ng\u0103 Marte. De asemenea, Rosetta va intra \u0219i va ie\u0219i din centura principal\u0103 de asteroizi situat\u0103 \u00eentre Marte \u0219i Jupiter. Acest lucru \u00eei va permite s\u0103 realizeze imagini de aproape ale a doi asteroizi, Steins \u0219i Lutetia.<\/p>\n

La sosirea \u00een apropierea cometei, Rosetta \u00ee\u0219i va reduce viteza \u0219i \u00ee\u0219i va modifica traiectoria, astfel \u00eenc\u00e2t s\u0103 intre pe orbit\u0103 la doar c\u00e2\u021biva kilometri deasupra nucleului solid.<\/p>\n

Odat\u0103 ce cometa va fi cartografiat\u0103, sonda Rosetta va elibera modulul s\u0103u de aterizare (numit Philae). Acesta se va ancora pe nucleu \u0219i va transmite primele imagini de pe suprafa\u021ba unei comete.<\/p>\n

De sus, sonda va urm\u0103ri cometa pe m\u0103sur\u0103 ce aceasta se \u00eendreapt\u0103 cu vitez\u0103 spre partea interioar\u0103 a Sistemului Solar. Pe parcursul acestei urm\u0103riri de 18 luni, ghea\u021ba \u00eenghe\u021bat\u0103 a cometei se va transforma \u00een gaz, arunc\u00e2nd jeturi de materie \u00een spa\u021biu. Rosetta ne va ar\u0103ta pentru prima dat\u0103 schimb\u0103rile spectaculoase care au loc pe m\u0103sur\u0103 ce acest \u201emunte de ghea\u021b\u0103\u201d din spa\u021biu este \u00eenc\u0103lzit de Soare.<\/p>","protected":false},"excerpt":{"rendered":"
