Na plan\u00e9te Mars sk\u00fama such\u00fa krajinu v oblasti delty Jezero, ktor\u00e1 bola kedysi, pred miliardami rokov, rie\u010dnym syst\u00e9mom. A sl\u00e1vny film pripom\u00edna aj ned\u00e1vny objav. Tak si teda pustite soundtrack do pozadia, nala\u010fte sa na vesm\u00edrnu vlnu a po\u010fte sa s nami pozrie\u0165 na to, \u010do presne sa stalo.<\/p>\n

Pr\u00edstroj RIMFAX na palube rovera teraz sk\u00famal kr\u00e1ter Jezero hlb\u0161ie ne\u017e kedyko\u013evek predt\u00fdm a odhalil nie\u010do nev\u00eddan\u00e9. Hovor\u00edme o rozsiahlom, prad\u00e1vnom deltovom syst\u00e9me, kde mohla by\u0165 kedysi te\u010d\u00faca voda.<\/p>\n

Vedci publikovali \u0161t\u00fadiu 18. marca v Science Advances<\/a> a \u010dl\u00e1nok priniesol Science Alert<\/a>.<\/p>\n

Ako dlho bola kvapaln\u00e1 voda na povrchu plan\u00e9ty?<\/p>\n

Po dlh\u00fdch rokoch intenz\u00edvneho v\u00fdskumu sa znova ukazuje, \u017ee Mars nebol v\u017edy suchou, pra\u0161nou gu\u013eou. Viacer\u00e9 d\u00f4kazy nazna\u010duj\u00fa, \u017ee voda tu kedysi tiekla v hojnom mno\u017estve.<\/p>\n

Vieme to v\u010faka tvaru krajiny<\/a>, ale aj pr\u00edtomnosti miner\u00e1lov, ktor\u00e9 mohli vznikn\u00fa\u0165 iba za \u00fa\u010dasti kvapalnej vody.<\/p>\n

A verte alebo nie, doteraj\u0161\u00ed v\u00fdskum priniesol najm\u00e4 jedno \u2013 e\u0161te viac ot\u00e1zok. Pokia\u013e ide o ob\u00fdvate\u013enos\u0165, najnaliehavej\u0161ia z nich znie: Ako dlho bola kvapaln\u00e1 voda na povrchu plan\u00e9ty?<\/p>\n

\u010c\u00edm dlh\u0161ie toto obdobie trvalo, t\u00fdm v\u00e4\u010d\u0161ie okno pr\u00edle\u017eitosti vzniklo pre potenci\u00e1lny vznik mikr\u00f3bov \u2013 najpravdepodobnej\u0161ej formy \u017eivota na Marse pod\u013ea s\u00fa\u010dasn\u00fdch vedeck\u00fdch predpokladov.<\/p>\n

Vedcov zaujal \u00fatvar zn\u00e1my ako Margin<\/p>\n

Dobrou spr\u00e1vou pre vedcov je, \u017ee na Marse neprebiehaj\u00fa rovnak\u00e9 tektonick\u00e9 a poveternostn\u00e9 procesy ako na Zemi. Krajina je preto mimoriadne dobre zachovan\u00e1.<\/p>\n

O oblasti kr\u00e1tera Jezero dnes predpoklad\u00e1me, \u017ee m\u00e1 pribli\u017ene 3,7 miliardy rokov. Pr\u00e1ve v tomto obdob\u00ed sa na plan\u00e9te nach\u00e1dzala te\u010d\u00faca povrchov\u00e1 voda, ktor\u00e1 podporovala v\u00fdraznej\u0161iu er\u00f3ziu aj ukladanie sedimentov. Vedcov v\u0161ak miatli niektor\u00e9 miner\u00e1lne lo\u017eisk\u00e1 v kr\u00e1teri.<\/p>\n

Pr\u00edkladom je \u00fatvar zn\u00e1my ako \u201eMargin\u201c, kde sa vo ve\u013ekom mno\u017estve nach\u00e1dzaj\u00fa uhli\u010ditany a oliv\u00edn. Pr\u00e1ve tieto nezrovnalosti viedli k \u010fal\u0161iemu prieskumu pomocou pr\u00edstroja RIMFAX, ktor\u00fd za\u010dal h\u013eada\u0165 nov\u00e9 ind\u00edcie, tentoraz pod povrchom plan\u00e9ty.<\/p>\n

Medzi septembrom 2023 a febru\u00e1rom 2024 vedci opakovane vykon\u00e1vali merania a uskuto\u010dnili celkovo 78 tzv. prechodov. \u00dadaje zhroma\u017e\u010fovali z trasy dlhej pribli\u017ene 6,1 kilometra a v procese prenikli do h\u013abky viac ne\u017e 35 metrov. Ke\u010f tieto d\u00e1ta za\u010dali sklada\u0165 do jedn\u00e9ho celku, z \u201etmy\u201c sa postupne vynorila skryt\u00e1 deltov\u00e1 krajina.<\/p>\n
