The Mars500 crewmembers also received training in the experiments they will perform during the simulation. From the end of March 2009, two European crewmembers will join four Russian-selected crewmembers inside a special isolation facility near Moscow. In the initial phase of the study, the crew will remain in the facility for 105 days. During this time they will experience a simulated human mission to Mars, including travelling to Mars, orbiting the planet, landing on the Martian surface and the return to Earth.
