Sonda je pozoruhodn\u011b neporu\u0161en\u00e1 a poskytuje cenn\u00e9 poznatky o tajemn\u00fdch okolnostech jej\u00edho zmizen\u00ed.<\/p>\n\n

Mise Beagle2<\/h2>\n\n

Sonda Beagle2, vypu\u0161t\u011bn\u00e1 v roce 2003 v r\u00e1mci mise Mars Express Evropsk\u00e9 kosmick\u00e9 agentury, byla pr\u016fkopnick\u00fdm po\u010dinem, jeho\u017e c\u00edlem bylo prozkoumat povrch a atmosf\u00e9ru Marsu. Sonda m\u011bla p\u0159ist\u00e1t na \u0160t\u011bdr\u00fd den, ale kontakt byl ztracen kr\u00e1tce po jej\u00edm vypu\u0161t\u011bn\u00ed z orbit\u00e1ln\u00edho modulu Mars Express.<\/p>\n\n

P\u00e1tr\u00e1n\u00ed a objev<\/h2>\n\n

P\u0159es rozs\u00e1hl\u00e9 p\u00e1trac\u00ed akce z\u016fstalo m\u00edsto pobytu sondy Beagle2 a\u017e do ned\u00e1vn\u00e9ho objevu nezn\u00e1m\u00e9. V\u011bdci pe\u010dliv\u011b analyzovali sn\u00edmky ve vysok\u00e9m rozli\u0161en\u00ed po\u0159\u00edzen\u00e9 kamerou HiRISE na palub\u011b Mars Reconnaissance Orbiteru, co\u017e vedlo k identifikaci d\u00e1vno ztracen\u00e9 sondy v r\u00e1mci jej\u00ed c\u00edlov\u00e9 p\u0159ist\u00e1vac\u00ed z\u00f3ny.<\/p>\n\n

Nepo\u0161kozen\u00fd stav a stopy poruchy<\/h2>\n\n

Objev sondy Beagle2 v jednom kuse zm\u00e1tl v\u011bdce, kte\u0159\u00ed d\u0159\u00edve spekulovali, \u017ee p\u0159ist\u00e1n\u00ed mohlo sondu zni\u010dit.

\u0160patn\u00e9 \u0161t\u011bst\u00ed nebo chyba v n\u00e1vrhu?<\/h2>\n\n

Mark Sims, mana\u017eer mise Beagle2, se domn\u00edv\u00e1, \u017ee porucha byla pravd\u011bpodobn\u011b zp\u016fsobena \u201e\u010distou sm\u016flou\u201c, jako nap\u0159\u00edklad siln\u00fd odraz deformoval strukturu nebo prop\u00edchnut\u00fd airbag zabr\u00e1nil rozvinut\u00ed.

Pou\u010den\u00ed a budouc\u00ed mise<\/h2>\n\n

Porucha sondy Beagle2 m\u011bla v\u00fdznamn\u00fd dopad na budouc\u00ed vesm\u00edrn\u00e9 mise a vedla k reform\u00e1m a vylep\u0161en\u00fdm komunika\u010dn\u00edm protokol\u016fm. Sond\u00e1m, jako je rover ExoMars, kter\u00fd m\u00e1 p\u0159ist\u00e1t na Marsu v roce 2019, jsou nyn\u00ed vybaveny tak, aby nav\u00e1zaly kontakt nejen po dosa\u017een\u00ed povrchu, ale tak\u00e9 b\u011bhem sestupu.<\/p>\n\n

Kontext a historick\u00fd v\u00fdznam<\/h2>\n\n

Beagle2 byla prvn\u00ed \u010dist\u011b evropsk\u00e1 mise na jinou planetu a jedna z nej\u00fasporn\u011bj\u0161\u00edch meziplanet\u00e1rn\u00edch mis\u00ed, jak\u00e9 kdy byly podniknuty. Jej\u00ed ztr\u00e1ta zd\u016fraznila v\u00fdzvy a rizika spojen\u00e1 s pr\u016fzkumem vesm\u00edru, ale tak\u00e9 uk\u00e1zala odolnost a odhodl\u00e1n\u00ed v\u011bdc\u016f odhalit tajemstv\u00ed Rud\u00e9 planety.<\/p>\n\n

Beagle2 nen\u00ed jedinou sondou, kter\u00e1 na Marsu potkala ne\u0161\u0165astn\u00fd osud.
