Nye billeder fra Mars Express viser en bjergk\u00e6de, vi ikke har set f\u00f8r. Bjergene ligger i et omr\u00e5de, hvor radarm\u00e5linger viser, at der gemmer sig store m\u00e6ngder vandis under overfladen, hvilket kunne v\u00e6re en vigtig vandkilde for fremtidige astronauter.<\/p>\n<\/div>\n

Bjergk\u00e6den hedder Phlegra Montes og str\u00e6kker sig fra den nord\u00f8stlige del af det vulkanske omr\u00e5de til det nordlige lavland. Selve bjergene er sandsynligvis ikke af vulkansk oprindelse, men er dannet af gamle tektoniske kr\u00e6fter, der pressede forskellige omr\u00e5der af jordskorpen sammen.<\/p>\n

Nye billeder fra det h\u00f8jopl\u00f8selige kamera p\u00e5 ESA\u2019s Mars Express giver os mulighed for at se bjergene i langt st\u00f8rre detalje end tidligere og viser os, at n\u00e6sten hvert eneste bjerg er omgivet af \u2018lobate debris aprons\u2019 \u2013 det vil sige buede klippestykker, der ligger under klipper som disse.<\/p>\n

Tidligere unders\u00f8gelser har vist, at disse klipper tilsyneladende med tiden er r\u00f8get ned ad bjergskr\u00e5ningerne og ligner det materiale, man finder p\u00e5 gletsjere her p\u00e5 Jorden. Det f\u00e5r forskerne til at tro, at der kunne v\u00e6re gletsjere begravet lige under overfladen p\u00e5 Mars.<\/p>\n

Der findes yderligere beviser p\u00e5 en forholdsvis nylig istid inde i nedslagskratrene i omr\u00e5det. Man mener, at en r\u00e6kke h\u00f8jderygge er opst\u00e5et, da de gamle kratere blev fyldt med sne. Med tiden blev sneen komprimeret og dannede gletsjere, som derefter formede kraterbundene.<\/p>\n

Alt dette f\u00e5r forskerne til at tro, at der kunne v\u00e6re store m\u00e6ngder vandis lige under overfladen i Phlegra Montes. Hvis dette viser sig at v\u00e6re sandt, kunne disse isfelter udg\u00f8re en vigtig vandkilde for fremtidige astronauter p\u00e5 den r\u00f8de planet.<\/p>","protected":false},"excerpt":{"rendered":"
