Mars500 is an international study about the possible interplanetary spaceflights and will conduct in 2010-2011 the first ever full duration simulation of a possible manned flight to Mars.

The 520-day simulation is the last and core part of the Mars500 experiment that began back in 2007. The first phase was a 14-day simulation that mainly tested the facilities and operational procedures. The second phase followed in 2009, when four Russian and two European crewmembers were shut into the facility for 105 days.

Mars500 is being conducted by Russia’s Institute of Biomedical Problems (IBMP), with extensive participation by ESA.
