Dup\u0103 o c\u0103l\u0103torie de 10 ani lungi, parcurg\u00e2nd peste jum\u0103tate din lungimea Sistemului Solar \u0219i \u00eenconjur\u00e2nd Soarele de cinci ori, sonda spa\u021bial\u0103 Rosetta a ajuns \u00een sf\u00e2r\u0219it la destina\u021bie: cometa 67P\/Churyumov\u2013Gerasimenko!<\/p>\n<\/div>\n

\u00cen prezent, Rosetta se afl\u0103 pe o orbit\u0103 la 100 km deasupra suprafe\u021bei cometei, trimi\u021b\u00e2nd pe P\u0103m\u00e2nt informa\u021bii detaliate despre noul s\u0103u \u201eprieten\u201d. \u00cen urm\u0103toarele c\u00e2teva s\u0103pt\u0103m\u00e2ni, sarcina principal\u0103 a misiunii Rosetta este aceea de a g\u0103si locul perfect de aterizare pentru sonda pe care o transport\u0103, numit\u0103 Philae (se pronun\u021b\u0103 FEE-lay).<\/p>\n

Dac\u0103 totul decurge conform planului, \u00een doar c\u00e2teva luni Philae va deveni prima sond\u0103 din istorie care va fi lansat\u0103 pe suprafa\u021ba unei comete!<\/p>\n

\u00cens\u0103 c\u0103l\u0103toria lui Rosetta nu se va \u00eencheia aici; timp de multe luni, mica sond\u0103 spa\u021bial\u0103 va c\u0103l\u0103tori al\u0103turi de comet\u0103 pe m\u0103sur\u0103 ce aceasta va orbita \u00een jurul Soarelui \u0219i se va \u00eendrepta din nou spre Jupiter.<\/p>\n

Peste un an, cele dou\u0103 corpuri cere\u0219ti se vor apropia de punctul cel mai apropiat de Soare \u00een c\u0103l\u0103toria lor prin Sistemul Solar \u2014 \u0219i tocmai acolo cometa va \u00eencepe cu adev\u0103rat s\u0103 str\u0103luceasc\u0103.<\/p>\n

Cometele sunt aglomer\u0103ri de ghea\u021b\u0103 \u0219i roc\u0103 cosmic\u0103, ceea ce \u00eenseamn\u0103 c\u0103, pe m\u0103sur\u0103 ce cometa 67P se apropie de Soare, va \u00eencepe s\u0103 se topeasc\u0103. Ghea\u021ba vaporizat\u0103 de pe comet\u0103 va crea o coad\u0103 magnific\u0103, asem\u0103n\u0103toare celor pe care, uneori, avem norocul s\u0103 le vedem travers\u00e2nd cerul.<\/p>\n

Din p\u0103cate, cometa 67P nu va fi vizibil\u0103 pe cerul nostru nocturn f\u0103r\u0103 telescoape puternice, chiar \u0219i cu coada sa str\u0103lucitoare. \u00cen schimb, sonda Rosetta ne va oferi ceva \u0219i mai bun \u2014 o priveli\u0219te de aproape a modului \u00een care cometa se transform\u0103 \u00een lumina orbitoare a Soarelui!<\/p>\n

Un fapt interesant<\/h2>\n

Misiunea poart\u0103 numele Pietrei din Rosetta, o tabl\u0103 de piatr\u0103 antic\u0103 care ne-a permis s\u0103 descifr\u0103m hieroglifele egiptene antice. La fel ca Piatra din Rosetta, misiunea \u201eRosetta\u201d a ESA va schimba radical modul \u00een care \u00een\u021belegem trecutul, dezv\u0103luind misterele obiectelor formate din r\u0103m\u0103\u0219i\u021bele din perioada \u00een care s-a format Sistemul nostru Solar: cometele.<\/p>","protected":false},"excerpt":{"rendered":"
