Forskare har analyserat vad som h\u00e4nde under den simulerade Mars500-expeditionen 2010\u20132011, vilket har gett dem en mycket b\u00e4ttre bild av de psykiska och fysiska problem som kan uppst\u00e5 under en Mars-expedition.<\/p>\n<\/div>\n<p>Bes\u00e4ttningen best\u00e5ende av sex \u2018marsonauter\u2019 var inl\u00e5sta i ett simulerat rymdskepp n\u00e4ra Moskva i Ryssland i 520 dagar. Det inneb\u00e4r att de var inl\u00e5sta i n\u00e4stan ett och ett halvt \u00e5r! Det \u00e4r den tid det tar att flyga till Mars och tillbaka, plus 30 dagar f\u00f6r att utforska ytan. Under sitt \u2018uppdrag\u2019 levde bes\u00e4ttningen isolerad, utan f\u00e4rsk mat, solljus eller frisk luft.
