Mars u\u017e dlouho fascinuje v\u011bdce i badatele a jednou z nejzaj\u00edmav\u011bj\u0161\u00edch ot\u00e1zek, kter\u00e1 se t\u00fdk\u00e1 Rud\u00e9 planety, je p\u0159\u00edtomnost vody. Zat\u00edmco na p\u00f3lech Marsu byl nalezen vodn\u00ed led, nalezen\u00ed kapaln\u00e9 vody nebo vody v jin\u00fdch form\u00e1ch bylo velkou v\u00fdzvou.<\/p>\n\n
Ned\u00e1vn\u00fd objev, kter\u00fd u\u010dinili v\u011bdci s vyu\u017eit\u00edm sondy ExoMars Trace Gas Orbiter (TGO), vrhl nov\u00e9 sv\u011btlo na vodn\u00ed zdroje na Marsu. S pomoc\u00ed p\u0159\u00edstroje zvan\u00e9ho FREND (Fine Resolution Epithermal Neutron Detector) v\u00fdzkumn\u00edci odhalili velk\u00e9 mno\u017estv\u00ed vod\u00edku t\u011bsn\u011b pod povrchem oblasti Valles Marineris na Marsu, co\u017e je rozs\u00e1hl\u00fd syst\u00e9m ka\u0148on\u016f.<\/p>\n\n
Valles Marineris je jedn\u00edm z nejv\u011bt\u0161\u00edch syst\u00e9m\u016f ka\u0148on\u016f ve Slune\u010dn\u00ed soustav\u011b, t\u00e1hne se p\u0159es tis\u00edce kilometr\u016f a dosahuje hloubek a\u017e 7 kilometr\u016f. P\u0159edpokl\u00e1d\u00e1 se, \u017ee vznikl p\u0159ed miliardami let tektonickou \u010dinnost\u00ed a eroz\u00ed.<\/p>\n\n
Uvnit\u0159 Valles Marineris le\u017e\u00ed oblast zvan\u00e1 Candor Chaos, kter\u00e1 byla nyn\u00ed identifikov\u00e1na jako obrovsk\u00e1 z\u00e1sob\u00e1rna vody. FREND detekoval vysok\u00e9 hladiny vod\u00edku v horn\u00ed vrstv\u011b marsovsk\u00e9 p\u016fdy v oblasti Candor Chaos, co\u017e nazna\u010duje p\u0159\u00edtomnost molekul vody.<\/p>\n\n
Pokud je ve\u0161ker\u00fd vod\u00edk zji\u0161t\u011bn\u00fd v oblasti Candor Chaos v\u00e1z\u00e1n do molekul vody, mohlo by to znamenat podpovrchovou vodn\u00ed oblast p\u0159ibli\u017en\u011b o velikosti Nizozemska. Tento objev m\u00e1 v\u00fdznamn\u00e9 d\u016fsledky pro budouc\u00ed lidsk\u00fd pr\u016fzkum Marsu, proto\u017ee nazna\u010duje, \u017ee astronauti by mohli m\u00edt snadn\u011bj\u0161\u00ed p\u0159\u00edstup k vodn\u00edm zdroj\u016fm.<\/p>\n\n
Voda v oblasti Candor Chaos pravd\u011bpodobn\u011b neexistuje v podob\u011b kapaln\u00fdch jezer, jak\u00e1 se nach\u00e1zej\u00ed na Zemi. V\u011bdci se naopak domn\u00edvaj\u00ed, \u017ee je s nejv\u011bt\u0161\u00ed pravd\u011bpodobnost\u00ed v podob\u011b ledu nebo vody v\u00e1zan\u00e9 na miner\u00e1ly. P\u0159esn\u00e1 distribuce a vlastnosti vody jsou st\u00e1le p\u0159edm\u011btem zkoum\u00e1n\u00ed.<\/p>\n\n
Oblast Valles Marineris se nach\u00e1z\u00ed pobl\u00ed\u017e rovn\u00edku Marsu, kde teplotn\u00ed a tlakov\u00e9 podm\u00ednky obecn\u011b nejsou p\u0159\u00edzniv\u00e9 pro vznik ledu nebo kapaln\u00e9 vody. V\u00fdzkumn\u00edci se v\u0161ak domn\u00edvaj\u00ed, \u017ee zvl\u00e1\u0161tn\u00ed geologick\u00e9 podm\u00ednky v oblasti Candor Chaos mohou umo\u017enit dopln\u011bn\u00ed vody a jej\u00ed udr\u017een\u00ed ve stabiln\u00edm stavu.<\/p>\n\n
Objev vody v oblasti Candor Chaos vyvolal nad\u0161en\u00ed a o\u010dek\u00e1v\u00e1n\u00ed ohledn\u011b budouc\u00edch pr\u016fzkumn\u00fdch mis\u00ed na Mars. V\u011bdci pl\u00e1nuj\u00ed prov\u00e9st dal\u0161\u00ed studie, aby ur\u010dili p\u0159esnou povahu vody a zp\u016fsob, jak\u00fdm je v t\u00e9to oblasti udr\u017eov\u00e1na. Budouc\u00ed mise se zam\u011b\u0159\u00ed na pr\u016fzkum ni\u017e\u0161\u00edch zem\u011bpisn\u00fdch \u0161\u00ed\u0159ek na Marsu, kde by mohly existovat podobn\u00e9 oblasti bohat\u00e9 na vodu.<\/p>\n\n
Pochopen\u00ed distribuce a vlastnost\u00ed vody na dne\u0161n\u00edm Marsu je z\u00e1sadn\u00ed pro odhalen\u00ed minulosti planety. Voda je nezbytn\u00e1 pro \u017eivot, jak ho zn\u00e1me, a jej\u00ed p\u0159\u00edtomnost na Marsu nazna\u010duje, \u017ee planeta mohla b\u00fdt kdysi obyvateln\u00e1. Objev vody v oblasti Candor Chaos poskytuje cenn\u00e9 poznatky o historii vody na Marsu a jej\u00edm potenci\u00e1lu pro budouc\u00ed obyvatelnost.<\/p>","protected":false},"excerpt":{"rendered":"
