Nya bilder fr\u00e5n Mars Express visar en bergskedja som vi inte har sett tidigare. Bergen ligger i ett omr\u00e5de d\u00e4r radarm\u00e4tningar visar att det d\u00f6ljer sig stora m\u00e4ngder vattenis under ytan, vilket skulle kunna utg\u00f6ra en viktig vattenk\u00e4lla f\u00f6r framtida astronauter.<\/p>\n<\/div>\n

Bergskedjan kallas Phlegra Montes och str\u00e4cker sig fr\u00e5n den nord\u00f6stra delen av vulkanomr\u00e5det till de norra l\u00e5glandet. Bergen i sig \u00e4r troligen inte av vulkaniskt ursprung, utan har bildats av forntida tektoniska krafter som pressade samman olika delar av jordytan.<\/p>\n

Nya bilder fr\u00e5n den h\u00f6guppl\u00f6sta kameran p\u00e5 ESA:s Mars Express g\u00f6r det m\u00f6jligt f\u00f6r oss att se bergen i mycket st\u00f6rre detalj \u00e4n tidigare och visar att n\u00e4stan varje berg \u00e4r omgivet av \u2018lobformade stenavlagringar\u2019 \u2013 det vill s\u00e4ga b\u00f6jda stenavlagringar som finns nedanf\u00f6r klippor som dessa.<\/p>\n

Tidigare studier har visat att dessa bergarter tycks ha r\u00f6rt sig nedf\u00f6r bergssluttningarna med tiden och att de liknar det material som man hittar p\u00e5 glaci\u00e4rer h\u00e4r p\u00e5 jorden. Detta f\u00e5r forskarna att tro att det kan finnas glaci\u00e4rer begravda strax under ytan p\u00e5 Mars.<\/p>\n

Ytterligare bevis p\u00e5 en relativt ny istid kan ses inuti nedslagskratrarna i regionen. Man tror att en rad \u00e5sar bildades n\u00e4r de forntida kratrarna fylldes med sn\u00f6. Med tiden komprimerades sn\u00f6n och bildade glaci\u00e4rer som sedan formade kraterbottnarna.<\/p>\n

Allt detta f\u00e5r forskarna att tro att det kan finnas stora m\u00e4ngder vattenis strax under ytan i Phlegra Montes. Om detta visar sig st\u00e4mma skulle dessa isf\u00e4lt kunna utg\u00f6ra en viktig vattenk\u00e4lla f\u00f6r framtida astronauter p\u00e5 den r\u00f6da planeten.<\/p>","protected":false},"excerpt":{"rendered":"
