Od srpna 2012 voz\u00edtko NASA Curiosity proj\u00ed\u017ed\u00ed mar\u0165anskou krajinou s kone\u010dn\u00fdm c\u00edlem, kter\u00fdm je hora Sharp, 3,4 m\u00edle vysok\u00e1 hora nach\u00e1zej\u00edc\u00ed se v kr\u00e1teru Gale. \u00dakolem voz\u00edtka Curiosity je prozkoumat vrstevnat\u00fd ter\u00e9n hory Sharp a hledat d\u016fkazy o minul\u00e9 vod\u011b a obyvateln\u00e9 prost\u0159ed\u00ed, kter\u00e9 by mohlo podporovat mikrobi\u00e1ln\u00ed \u017eivot.<\/p>\n\n
Hora Sharp, zn\u00e1m\u00e1 tak\u00e9 jako Aeolis Mons, je vrstevnat\u00fd kopec, kter\u00fd se ty\u010d\u00ed v\u00edce ne\u017e 3 m\u00edle nad dnem kr\u00e1teru Gale.

V\u011bdci se domn\u00edvaj\u00ed, \u017ee hora Sharp m\u016f\u017ee obsahovat stopy po vodn\u00ed minulosti Marsu. P\u0159\u00edstroje voz\u00edtka jsou navr\u017eeny tak, aby detekovaly zn\u00e1mky minul\u00e9 vody, jako jsou miner\u00e1ly, kter\u00e9 se tvo\u0159\u00ed za p\u0159\u00edtomnosti kapaln\u00e9 vody. Curiosity ji\u017e objevila d\u016fkazy o star\u00e9m dn\u011b jezera v kr\u00e1teru Gale a pokra\u010duje v pr\u016fzkumu ni\u017e\u0161\u00edch svah\u016f hory Sharp, kde v\u011bdci doufaj\u00ed, \u017ee najdou p\u0159esv\u011bd\u010div\u011bj\u0161\u00ed d\u016fkazy o minul\u00e9 vod\u011b a obyvateln\u00e9 prost\u0159ed\u00ed.<\/p>\n\n
Pr\u016fzkum hory Sharp je slo\u017eit\u00fd a n\u00e1ro\u010dn\u00fd \u00fakol. Voz\u00edtko se mus\u00ed pohybovat v \u010dlenit\u00e9m ter\u00e9nu, extr\u00e9mn\u00edch teplot\u00e1ch a s omezen\u00fdmi energetick\u00fdmi zdroji. Krom\u011b toho je mar\u0165ansk\u00e1 atmosf\u00e9ra \u0159\u00eddk\u00e1 a pra\u0161n\u00e1, co\u017e m\u016f\u017ee naru\u0161ovat komunikaci a sb\u011br slune\u010dn\u00ed energie.<\/p>\n\n
Zji\u0161t\u011bn\u00ed Curiosity na ho\u0159e Sharp maj\u00ed z\u00e1sadn\u00ed v\u00fdznam pro na\u0161e ch\u00e1p\u00e1n\u00ed historie Marsu a potenci\u00e1lu \u017eivota. Objevy voz\u00edtka poskytly d\u016fkazy o tom, \u017ee Mars byl kdysi teplej\u0161\u00ed, vlh\u010d\u00ed planetou s podm\u00ednkami, kter\u00e9 mohly podporovat mikrobi\u00e1ln\u00ed \u017eivot.<\/p>\n\n
Mise Curiosity na ho\u0159e Sharp je v\u00fdznamn\u00fdm krokem vp\u0159ed v na\u0161em pr\u016fzkumu Marsu. Objevy voz\u00edtka pom\u00e1haj\u00ed v\u011bdc\u016fm rekonstruovat geologickou a environment\u00e1ln\u00ed historii planety a posoudit jej\u00ed potenci\u00e1l pro minul\u00fd a sou\u010dasn\u00fd \u017eivot. Budouc\u00ed mise na Mars budou stav\u011bt na objevech Curiosity a budou pokra\u010dovat v pr\u016fzkumu rud\u00e9 planety a jej\u00edch mnoha tajemstv\u00ed.<\/p>\n\n
NASA zve\u0159ejnila vysokorozlivostn\u00ed panorama hory Sharp po\u0159\u00edzen\u00e9 p\u0159\u00edstrojem Mastcam voz\u00edtka Curiosity. Panorama poskytuje \u00fa\u017easn\u00fd pohled na povrch hory a odhaluje jeho slo\u017eit\u00e9 vrstven\u00ed a geologick\u00e9 rysy.<\/p>\n\n
Kr\u00e1ter Gale, ve kter\u00e9m se hora Sharp nach\u00e1z\u00ed, je obrovsk\u00fd impaktn\u00ed kr\u00e1ter, kter\u00fd vznikl p\u0159ed miliardami let. Dno kr\u00e1teru pokr\u00fdvaj\u00ed sedimenty, kter\u00e9 byly erodov\u00e1ny z hory Sharp a dal\u0161\u00edho okoln\u00edho ter\u00e9nu. Pr\u016fzkum kr\u00e1teru Gale voz\u00edtkem Curiosity poskytl cenn\u00e9 poznatky o geologick\u00fdch procesech, kter\u00e9 formovaly povrch Marsu.<\/p>\n\n
Objevy Curiosity na ho\u0159e Sharp poskytly siln\u00e9 d\u016fkazy o tom, \u017ee Mars kdysi m\u011bl mnohem hust\u0161\u00ed atmosf\u00e9ru a tekouc\u00ed vodu na sv\u00e9m povrchu. Voz\u00edtko na\u0161lo d\u016fkazy o star\u00fdch \u0159\u00ed\u010dn\u00edch korytech, jezern\u00edch dnech a miner\u00e1lech, kter\u00e9 se tvo\u0159\u00ed v p\u0159\u00edtomnosti vody. Tato zji\u0161t\u011bn\u00ed nazna\u010duj\u00ed, \u017ee Mars mohl b\u00fdt obyvateln\u00fd pro mikrobi\u00e1ln\u00ed \u017eivot p\u0159ed miliardami let.<\/p>\n\n
Objev minul\u00e9 vody na Marsu vyvol\u00e1v\u00e1 mo\u017enost, \u017ee planeta mohla kdysi ukr\u00fdvat mikrobi\u00e1ln\u00ed \u017eivot. P\u0159\u00edstroje Curiosity jsou navr\u017eeny tak, aby hledaly zn\u00e1mky minul\u00e9ho nebo sou\u010dasn\u00e9ho \u017eivota, v\u010detn\u011b organick\u00fdch molekul a biomarker\u016f. Zji\u0161t\u011bn\u00ed voz\u00edtka pomohou v\u011bdc\u016fm posoudit potenci\u00e1l \u017eivota na Marsu a nasm\u011brovat budouc\u00ed mise p\u0159i hled\u00e1n\u00ed mimozemsk\u00e9ho \u017eivota.<\/p>\n\n
