Jedna z nejzaj\u00edmav\u011bj\u0161\u00edch kapitol v historii pr\u016fzkumu vesm\u00edru se pr\u00e1v\u011b chyst\u00e1 za\u010d\u00edt. Po cest\u011b dlouh\u00e9 3 miliardy km, kter\u00e1 trvala v\u00edce ne\u017e sedm let, je sonda Huygens agentury ESA p\u0159ipravena p\u0159ist\u00e1t na Titanu, nejv\u011bt\u0161\u00edm m\u011bs\u00edci Saturnu.<\/p>\n<\/div>\n

Na \u0160t\u011bdr\u00fd den se sonda Huygens pomalu odd\u011bl\u00ed od mate\u0159sk\u00e9 sondy Cassini. Tato mal\u00e1 sonda ve tvaru tal\u00ed\u0159e, kter\u00e1 se ot\u00e1\u010d\u00ed 7kr\u00e1t za minutu, se \u0159\u00edt\u00ed jako \u0161\u00edp sm\u011brem k m\u011bs\u00edci zahalen\u00e9mu smogem.<\/p>\n

Po 20 dnech sp\u00e1nku ji probud\u00ed palubn\u00ed hodiny. 14. ledna sonda vlet\u00ed do horn\u00ed atmosf\u00e9ry Titanu rychlost\u00ed p\u0159ibli\u017en\u011b 6 km za sekundu \u2013 co\u017e je desetkr\u00e1t rychleji ne\u017e Concorde.<\/p>\n
