V mnogih pogledih je Mars od vseh planetov tisti, ki je najbolj podoben Zemlji. Obiskovalec bi ugotovil, da je dan na Marsu le nekoliko dalj\u0161i od dneva na Zemlji. Mars je prav tako nagnjen pribli\u017eno v enakem kotu kot Zemlja, zato ima letne \u010dase.<\/p>\n<\/div>\n

Tako Mars kot Zemlja imata bele polarne kapice. Tiste na Marsu so precej manj\u0161e in tanj\u0161e, zato se pozimi hitro pove\u010dajo, poleti pa skoraj izginejo. So precej hladnej\u0161e od polarnih kapic na Zemlji, zato vsebujejo zamrznjen ogljikov dioksid (\u2018suhi led\u2019, ki se uporablja za ustvarjanje megle v gledali\u0161kih predstavah) ter vodni led.<\/p>\n

Razpoke na Marsu ka\u017eejo na prisotnost vode<\/figcaption><\/figure>\n

Mars se nahaja sredi ledene dobe, zato na njegovi povr\u0161ini trenutno ne more obstajati teko\u010da voda. Vendar pa se zdi, da je bil planet v preteklosti toplej\u0161i in vla\u017enej\u0161i.<\/p>\n

Na posnetkih vesoljskih plovil so opazili vijugaste kanale, ki spominjajo na suha re\u010dna dna. Ti ka\u017eejo, da so neko\u010d po povr\u0161ini tekle ogromne koli\u010dine vode \u2013 verjetno zaradi taljenja ledu. Morda je celo de\u017eevalo in sne\u017eilo. Zdi se, da so mnogi kanali zapolnili velike kraterje ali se izlivali na severne ravnine. Nekateri znanstveniki menijo, da je severno polovico Marsa neko\u010d pokrival velik ocean.<\/p>\n

Kam je izginila voda? Del je morda u\u0161el v vesolje. Preostanek je zamrznjen v tleh.<\/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.
