Povr\u0161ina Marsa je danes suha kot pu\u0161\u010dava, vendar najnovej\u0161i rezultati misije Mars Express agencije ESA potrjujejo, da je voda v zgodovini tega planeta igrala pomembno vlogo. Ob\u010dutljivi instrumenti vesoljskega plovila potrjujejo, da je bil suhi Rde\u010di planet neko\u010d precej vla\u017enej\u0161i in da je pod povr\u0161ino verjetno raz\u0161irjen vodni led.<\/p>\n<\/div>\n

V nekaj tednih lansko poletje je radarski instrument na sondi oddajal radijske signale, ki so pre\u0161li skozi povr\u0161ino in se odbijali od podzemnih plasti. Analiza teh odmevov je razkrila ukrivljene strukture, ki bi lahko bile zunanji robovi zakopanih udarnih kotlin.<\/p>\n

Ena skoraj kro\u017ena struktura s premerom pribli\u017eno 250 km le\u017ei 1,5 do 2,5 km pod severnimi ni\u017einami obmo\u010dja Chryse Planitia. Znanstveniki menijo, da bi lahko vsebovala debelo plast snovi, bogate z vodnim ledom. Bli\u017eje severnemu polu Marsa mo\u010dni odmevi ka\u017eejo na prisotnost skoraj \u010diste plasti vodnega ledu, debele ve\u010d kot 1 km, ki le\u017ei nad plastjo vulkanske \u201cprsti\u201d.<\/p>\n

Radar MARSIS se je uporabljal tudi za preu\u010devanje zgornjega dela atmosfere \u2013 ionosfere. Odmevi ka\u017eejo na mo\u010dno povezavo med obna\u0161anjem nabitega plina v tem obmo\u010dju in obmo\u010dji mo\u010dnega magnetizma v trdni skorji planeta.<\/p>\n

Drugi instrument, znan pod imenom OMEGA, je zaznal kamnite minerale, ki jih je spremenila teko\u010da voda. Ti \u2018hidratirani\u2019 minerali dokazujejo, da so na Marsu pred milijardami let obstajale velike koli\u010dine vode \u2013 in da so bile takrat razmere morda primerne za nastanek \u017eivljenja.<\/p>","protected":false},"excerpt":{"rendered":"
