The Mars 500 mission simulates a round trip to the Red Planet, without stepping foot off Earth. Almost a year and a half ago, six men entered the windowless isolation chamber at the Russian Institute for Biomedical Problems in Moscow. Since then, they have mimicked various stages of a Mars mission. On 4 November, Mars 550 "landed" at 14:00 Moscow time.

Read more about the challenges of the journey, the excitement of the simulated Mars landing and how the ground crew is helping the inmates survive the experience.
