Mise Rosetta<\/h2>\n\n

Mise Rosetta Evropsk\u00e9 vesm\u00edrn\u00e9 agentury byla pr\u016fkopnick\u00fdm projektem, kter\u00fd trval 12 let. Sonda byla vypu\u0161t\u011bna v roce 2004 a vydala se na cestu ke komet\u011b 67P\/\u010curjumov-Gerasimenko. Po desetilet\u00ed trvaj\u00edc\u00ed cest\u011b kone\u010dn\u011b Rosetta v roce 2014 dorazila ke sv\u00e9mu c\u00edli.<\/p>\n\n

Jedn\u00edm z vrchol\u016f mise Rosetta bylo vysazen\u00ed p\u0159ist\u00e1vac\u00edho modulu Philae v listopadu 2014. Bohu\u017eel z\u00e1vada v jedn\u00e9 z harpunov\u00fdch kotev zp\u016fsobila, \u017ee Philae odsko\u010dil a p\u0159ist\u00e1l ve st\u00ednu \u00fatesu, kde nemohl p\u0159ij\u00edmat dostatek slune\u010dn\u00edho sv\u011btla pro nap\u00e1jen\u00ed sv\u00fdch p\u0159\u00edstroj\u016f.<\/p>\n\n

Sonda se dost\u00e1vala na st\u00e1le t\u011bsn\u011bj\u0161\u00ed orbity a poskytovala v\u011bdc\u016fm bezprecedentn\u00ed pohledy na povrch a atmosf\u00e9ru komety.<\/p>\n\n

    Mise Rosetta byla oslavov\u00e1na jako ohromn\u00fd \u00fasp\u011bch. Poskytla v\u011bdc\u016fm neb\u00fdval\u00e9 mno\u017estv\u00ed dat o komet\u00e1ch a pomohla objasnit p\u016fvod na\u0161\u00ed slune\u010dn\u00ed soustavy.<\/p>\n\n

    Cesta ke komet\u011b<\/h2>\n\n

    Cesta sondy Rosetta ke komet\u011b 67P byla pozoruhodn\u00fdm \u00fasp\u011bchem v oblasti in\u017een\u00fdrstv\u00ed a v\u011bdeck\u00e9ho pr\u016fzkumu. Sonda urazila p\u0159es 4 miliardy mil a str\u00e1vila v\u00edce ne\u017e dva roky na ob\u011b\u017en\u00e9 dr\u00e1ze kolem komety.

Sonda po\u0159\u00eddila sn\u00edmky s vysok\u00fdm rozli\u0161en\u00edm j\u00e1dra komety a zm\u011b\u0159ila jej\u00ed magnetick\u00e9 pole a plazmov\u00e9 prost\u0159ed\u00ed.<\/p>\n\n
