Sok szempontb\u00f3l a Mars a legink\u00e1bb a F\u00f6ldh\u00f6z hasonl\u00f3 bolyg\u00f3. Egy l\u00e1togat\u00f3 azt tapasztaln\u00e1, hogy a marsi nap csak kiss\u00e9 hosszabb, mint a f\u00f6ldi. A Mars tengelyd\u0151l\u00e9se is nagyj\u00e1b\u00f3l megegyezik a F\u00f6ld\u00e9vel, ez\u00e9rt ott is vannak \u00e9vszakok.<\/p>\n<\/div>\n

A Marsnak \u00e9s a F\u00f6ldnek egyar\u00e1nt vannak feh\u00e9r sarkvid\u00e9ki j\u00e9gsapk\u00e1i. A marsi j\u00e9gsapk\u00e1k sokkal kisebbek \u00e9s v\u00e9konyabbak, ez\u00e9rt t\u00e9len gyorsan megn\u0151nek, ny\u00e1ron pedig szinte teljesen elt\u0171nnek. Sokkal hidegebbek, mint a F\u00f6ld sarkvid\u00e9ki j\u00e9gsapk\u00e1i, ez\u00e9rt v\u00edzj\u00e9g mellett fagyott sz\u00e9n-dioxidot is tartalmaznak (azt a \u2018sz\u00e1razj\u00e9get\u2019, amelyet sz\u00ednpadi el\u0151ad\u00e1sokon k\u00f6d l\u00e9trehoz\u00e1s\u00e1ra haszn\u00e1lnak).<\/p>\n

\"Cracks
A Marson tal\u00e1lhat\u00f3 reped\u00e9sek v\u00edz jelenl\u00e9t\u00e9re utalnak<\/figcaption><\/figure>\n

A Mars jelenleg egy j\u00e9gkorszak k\u00f6zep\u00e9n van, ez\u00e9rt felsz\u00edn\u00e9n jelenleg nem l\u00e9tezhet foly\u00e9kony v\u00edz. \u00dagy t\u0171nik azonban, hogy a bolyg\u00f3 a m\u00faltban melegebb \u00e9s nedvesebb volt.<\/p>\n

Az \u0171rhaj\u00f3k \u00e1ltal k\u00e9sz\u00edtett felv\u00e9teleken kanyarg\u00f3s csatorn\u00e1k l\u00e1that\u00f3k, amelyek kisz\u00e1radt foly\u00f3medrekre eml\u00e9keztetnek. Ezek arra utalnak, hogy egykor hatalmas mennyis\u00e9g\u0171 v\u00edz \u00e1ramlott a felsz\u00ednen \u2013 val\u00f3sz\u00edn\u0171leg az olvad\u00f3 j\u00e9g t\u00e1pl\u00e1lta. Lehet, hogy es\u0151 \u00e9s h\u00f3 is esett. \u00dagy t\u0171nik, hogy a csatorn\u00e1k k\u00f6z\u00fcl sok kit\u00f6lt\u00f6tt nagy kr\u00e1tereket, vagy az \u00e9szaki s\u00edks\u00e1gra \u00f6ml\u00f6tt. Egyes tud\u00f3sok \u00fagy v\u00e9lik, hogy egykor egy hatalmas \u00f3ce\u00e1n bor\u00edtotta a Mars \u00e9szaki fel\u00e9t.<\/p>\n

Hov\u00e1 t\u0171nt a v\u00edz? Egy r\u00e9sze tal\u00e1n az \u0171rbe sziv\u00e1rgott ki. A t\u00f6bbi pedig a talajban fagyott meg.<\/p>","protected":false},"excerpt":{"rendered":"
