Europeiska forskare vill skicka en rover f\u00f6r att s\u00f6ka efter tecken p\u00e5 liv p\u00e5 Mars. Det var budskapet efter ett tv\u00e5dagarsm\u00f6te inom ESA som h\u00f6lls f\u00f6rra veckan i Birmingham, England.<\/p>\n<\/div>\n

Mars \u00e4r den planet som mest liknar jorden, och den plats \u2013 bortsett fr\u00e5n jorden \u2013 d\u00e4r det \u00e4r mest troligt att primitivt liv skulle kunna existera. Uppgifter fr\u00e5n ESA:s rymdsond Mars Express tyder p\u00e5 att den r\u00f6da planeten en g\u00e5ng var betydligt varmare och fuktigare \u00e4n den \u00e4r idag.<\/p>\n

Finns det flytande vatten under dess frusna yta? Om s\u00e5 \u00e4r fallet, finns det d\u00e5 enkla livsformer d\u00e4r? F\u00f6r att f\u00e5 svar p\u00e5 dessa g\u00e5tor vill forskarna utforska Mars yta med en toppmodern rover.<\/p>\n

Den f\u00f6reslagna rymdresan skulle inledas i juni 2011. Efter en tv\u00e5\u00e5rig resa skulle krockkuddar och eventuellt bromsraketer anv\u00e4ndas f\u00f6r att d\u00e4mpa roverns landning p\u00e5 Mars.<\/p>\n

En av dess huvuduppgifter skulle vara att s\u00f6ka efter sp\u00e5r av liv \u2013 b\u00e5de fr\u00e5n det f\u00f6rflutna och i nutiden. I roverns nyttolast skulle det ing\u00e5 ett gasanalysf\u00f6rs\u00f6k f\u00f6r att leta efter kemiska tecken p\u00e5 liv i atmosf\u00e4ren.<\/p>\n

En borr p\u00e5 rovern skulle ta sten- och jordprover fr\u00e5n ett djup p\u00e5 2 meter. Dessa skulle ocks\u00e5 unders\u00f6kas med hj\u00e4lp av gasanalysf\u00f6rs\u00f6ket.<\/p>\n

Andra instrument p\u00e5 rovern skulle s\u00f6ka efter vatten, unders\u00f6ka bergartslagren under ytan och m\u00e4ta marsb\u00e4vningar. De skulle ocks\u00e5 identifiera faror som skulle kunna utg\u00f6ra ett hot mot framtida bemannade rymduppdrag.<\/p>\n

Med blicken riktad mot framtiden bekr\u00e4ftade forskarna sitt \u00e5tagande att delta i en internationell provh\u00e4mtningsmission \u00e5r 2016.<\/p>","protected":false},"excerpt":{"rendered":"
