Misiunea Cassini-Huygens, la care au participat ESA, NASA \u0219i Agen\u021bia Spa\u021bial\u0103 Italian\u0103, a schimbat multe dintre concep\u021biile noastre despre sistemul lui Saturn. Lansat\u0103 din Florida \u00een octombrie 1997, a durat aproape \u0219apte ani p\u00e2n\u0103 a ajuns la Saturn, parcurg\u00e2nd aproape 3,5 miliarde de kilometri. Nava spa\u021bial\u0103 de 5,6 tone era alc\u0103tuit\u0103 din dou\u0103 p\u0103r\u021bi \u2013 orbiterul Cassini \u0219i sonda Huygens.<\/p>\n<\/div>\n

Cassini este prima sond\u0103 spa\u021bial\u0103 care orbiteaz\u0103 \u00een jurul lui Saturn. Aceasta transport\u0103 12 experimente. De la sosirea sa la Saturn, la 1 iulie 2004, Cassini a transmis cantit\u0103\u021bi uria\u0219e de informa\u021bii noi despre Saturn, inelele sale, lunile sale \u0219i c\u00e2mpul s\u0103u magnetic.<\/p>\n

Planificat\u0103 ini\u021bial ca o misiune de patru ani, misiunea Cassini-Huygens a avut un succes at\u00e2t de mare \u00eenc\u00e2t a fost prelungit\u0103 p\u00e2n\u0103 cel pu\u021bin \u00een 2017. Aceasta a survolat \u0219apte dintre sateli\u021bii mai mari, inclusiv gigantul Titan \u2013 care este mai mare dec\u00e2t planeta Mercur. Sonda orbital\u0103 a trecut pe l\u00e2ng\u0103 Titan de peste 70 de ori. Zbur\u00e2nd la o distan\u021b\u0103 de 880 km de satelit, a studiat norii portocalii ai lui Titan \u0219i atmosfera sa bogat\u0103 \u00een azot. De asemenea, a cartografiat suprafa\u021ba acestuia cu ajutorul unui radar de imagistic\u0103.<\/p>\n

\u00cen ziua de Cr\u0103ciun din 2004, Huygens s-a separat de Cassini. Trei s\u0103pt\u0103m\u00e2ni mai t\u00e2rziu, sonda a p\u0103truns cu vitez\u0103 \u00een atmosfera dens\u0103 a lui Titan, devenind prima sond\u0103 care a cobor\u00e2t pe suprafa\u021ba unui satelit planetar (\u00een afar\u0103 de Luna noastr\u0103). Protejat\u0103 de un scut termic, sonda \u0219i-a redus viteza de la 18.000 la 1.400 km pe or\u0103 \u00een doar trei minute. La scurt timp dup\u0103 aceea, s-a deschis o para\u0219ut\u0103 mare. La o \u00een\u0103l\u021bime de aproximativ 160 km, sonda a \u00eenceput s\u0103 fac\u0103 fotografii \u0219i s\u0103 studieze atmosfera. Timp de peste dou\u0103 ore, datele transmise de Huygens au fost recep\u021bionate \u0219i stocate pe sonda Cassini, \u00een timp ce aceasta zbura deasupra sa.<\/p>\n

Imaginile \u0219i celelalte informa\u021bii transmise de cele \u0219ase instrumente ale sale ne-au dezv\u0103luit pentru prima dat\u0103 cum arat\u0103 cu adev\u0103rat aceast\u0103 lun\u0103 portocalie. Huygens a aterizat pe albia uscat\u0103 a unui r\u00e2u, acoperit\u0103 cu mici bolovani \u00eenghe\u021ba\u021bi.<\/p>","protected":false},"excerpt":{"rendered":"
