(Note: all actions have been simulated.)

The facility:

• four hermetically sealed interconnected habitat modules
• one external module, 'martian surface'
• total volume of the habitat modules is 550 m3.

During the mission:

• the crew is hermetically isolated
• ‘surface operations’ after 250 days the crew will be divided in half, three will move to the martian surface simulator and three will remain in the ‘spacecraft’
• crew live and work like astronauts on ISS
• maintenance, scientific experiments and daily exercise.
• a seven-day week, with two days off, except when special and emergency situations are simulated.
• crew monitored and their psychological, medical and physical signs recorded
• limited consumables
• connection disrupted and with a realistic delays
• communications delay varies from 8 to 736 sec with maximum delay on flight day 351

Mars500 is being conducted by Russia’s Institute of Biomedical Problems (IBMP), with extensive participation by ESA as part of its European Programme for Life and Physical Sciences (ELIPS) to prepare for future human missions to the Moon and Mars.
