In 2006 three existing modules were re-equipped completely, new life support systems were created, systems of maintenance of temperature regime and water supply. In 2007 specially for "Mars-500" project an additional, forth hermetical module was built with the volume of 250 m3 (EU-250). At the beginning of 2008 building of the fifth module with simulation of the Martian surface began. After its completion the whole facility will be ready completely for "Mars-500" experiment
