En muchos sentidos, Marte es el planeta que m\u00e1s se parece a la Tierra. Un visitante encontrar\u00eda que un d\u00eda en Marte es s\u00f3lo ligeramente m\u00e1s largo que en la Tierra. Adem\u00e1s, Marte tiene casi la misma inclinaci\u00f3n que nuestro planeta, y por tanto tambi\u00e9n posee estaciones.<\/p>\n<\/div>\n

Tanto Marte como la Tierra tienen casquetes polares blancos. Los de Marte son mucho m\u00e1s peque\u00f1os y delgados, por lo que crecen r\u00e1pidamente en invierno y casi desaparecen en verano. Son mucho m\u00e1s fr\u00edos que los casquetes polares de la Tierra, por lo que contienen di\u00f3xido de carbono congelado (el \u2018hielo seco\u2019 que se utiliza para crear niebla en los espect\u00e1culos teatrales), adem\u00e1s de hielo de agua.<\/p>\n

Da sich Mars gerade mitten in einer Eiszeit befindet, kann es derzeit kein fl\u00fcssiges Wasser auf seiner Oberfl\u00e4che geben. Es sieht allerdings so aus, als sei der Planet einst w\u00e4rmer und feuchter gewesen.<\/p>\n

Bilder, die von Raumsonden aufgenommen wurden, zeigen sich \u00fcber den Boden schl\u00e4ngelnde Kan\u00e4le, die an ausgetrocknete Flussbetten erinnern. Es kann also sein, dass zu fr\u00fcheren Zeiten riesige Wassermengen \u00fcber die Marsoberfl\u00e4che flossen, die m\u00f6glicherweise durch schmelzendes Eis gespeist wurden. Denkbar ist auch, dass es dort regnete und schneite. Viele der Kan\u00e4le scheinen gro\u00dfe Krater angef\u00fcllt oder sich in die Ebenen im Norden ergossen zu haben. Einigen Wissenschaftlern zufolge war die n\u00f6rdliche Marsh\u00e4lfte von einem gro\u00dfen Meer bedeckt.<\/p>\n

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.
