Pod wieloma wzgl\u0119dami Mars jest spo\u015br\u00f3d wszystkich planet najbardziej podobny do Ziemi. Odwiedzaj\u0105cy zauwa\u017cy\u0142by, \u017ce dzie\u0144 na Marsie jest tylko nieznacznie d\u0142u\u017cszy ni\u017c na Ziemi. Mars ma r\u00f3wnie\u017c podobny k\u0105t nachylenia osi obrotu jak Ziemia, dlatego wyst\u0119puj\u0105 na nim pory roku.<\/p>\n<\/div>\n

Zar\u00f3wno Mars, jak i Ziemia maj\u0105 bia\u0142e czapy polarne. Te na Marsie s\u0105 znacznie mniejsze i cie\u0144sze, dlatego zim\u0105 szybko si\u0119 powi\u0119kszaj\u0105, a latem niemal ca\u0142kowicie znikaj\u0105. S\u0105 one znacznie zimniejsze ni\u017c czapy polarne na Ziemi, dlatego zawieraj\u0105 zar\u00f3wno zamro\u017cony dwutlenek w\u0119gla (tzw. \u2018suchy l\u00f3d\u2019, u\u017cywany do tworzenia mg\u0142y podczas przedstawie\u0144 scenicznych), jak i l\u00f3d wodny.<\/p>\n

\"Cracks
P\u0119kni\u0119cia na Marsie wskazuj\u0105 na obecno\u015b\u0107 wody<\/figcaption><\/figure>\n

Mars znajduje si\u0119 w \u015brodku epoki lodowcowej, wi\u0119c obecnie na jego powierzchni nie mo\u017ce wyst\u0119powa\u0107 woda w stanie ciek\u0142ym. Wydaje si\u0119 jednak, \u017ce w przesz\u0142o\u015bci planeta ta by\u0142a cieplejsza i bardziej wilgotna.<\/p>\n

Na zdj\u0119ciach wykonanych przez sondy kosmiczne wida\u0107 kr\u0119te kana\u0142y przypominaj\u0105ce wyschni\u0119te koryta rzek. Sugeruj\u0105 one, \u017ce niegdy\u015b po powierzchni p\u0142yn\u0119\u0142y ogromne ilo\u015bci wody \u2013 prawdopodobnie pochodz\u0105cej z topniej\u0105cego lodu. By\u0107 mo\u017ce wyst\u0119powa\u0142y tam nawet opady deszczu i \u015bniegu. Wiele z tych kana\u0142\u00f3w wydaje si\u0119 wype\u0142nia\u0107 du\u017ce kratery lub uchodzi\u0107 na p\u00f3\u0142nocne r\u00f3wniny. Niekt\u00f3rzy naukowcy uwa\u017caj\u0105, \u017ce p\u00f3\u0142nocn\u0105 po\u0142ow\u0119 Marsa pokrywa\u0142 niegdy\u015b rozleg\u0142y ocean.<\/p>\n

Gdzie podzia\u0142a si\u0119 woda? Cz\u0119\u015b\u0107 mog\u0142a przedosta\u0107 si\u0119 w przestrze\u0144 kosmiczn\u0105. Reszta jest zamro\u017cona w ziemi.<\/p>","protected":false},"excerpt":{"rendered":"

In many ways, Mars is the most Earthlike of all the planets. A visitor would find that a day on Mars is only slightly longer than one on Earth.
