V b\u0159eznu 1986 se sonda Giotto agentury ESA p\u0159ibl\u00ed\u017eila k j\u00e1dru Halleyovy komety na vzd\u00e1lenost 600 km. Poslala zp\u011bt prvn\u00ed detailn\u00ed sn\u00edmky ledov\u00e9ho j\u00e1dra komety. Nyn\u00ed je na cest\u011b k komet\u011b dal\u0161\u00ed sonda ESA s n\u00e1zvem Rosetta. Rosetta je nejslo\u017eit\u011bj\u0161\u00ed vesm\u00edrn\u00e1 mise, jakou Evropa kdy realizovala.<\/p>\n<\/div>\n

Sonda Rosetta, vypu\u0161t\u011bn\u00e1 2. b\u0159ezna 2004, bude pot\u0159ebovat 10 let, ne\u017e doraz\u00ed ke komet\u011b \u010curjumov-Gerasimenko. Jej\u00ed oklika zahrnuje t\u0159i pr\u016flety kolem Zem\u011b a jeden kolem Marsu. Sonda Rosetta tak\u00e9 n\u011bkolikr\u00e1t vlet\u00ed do hlavn\u00edho p\u00e1su asteroid\u016f mezi Marsem a Jupiterem a zase z n\u011bj vylet\u00ed.

Jakmile bude kometa zmapov\u00e1na, sonda Rosetta vypust\u00ed sv\u016fj p\u0159ist\u00e1vac\u00ed modul (nazvan\u00fd Philae). Ten se ukotv\u00ed na j\u00e1dru komety a po\u0161le zp\u011bt prvn\u00ed sn\u00edmky z povrchu komety.<\/p>\n
