The group's leader，engineer Sytev，looks at the three­square­meter place that will be his personal habitation.“This phone will work for only 11 days.When we are near the Earth，it will be switched off，” said Sytev.Sytev is a newly­wed.He says the most difficult thing will be to be separated from his wife and the persons around him.He finds it difficult to leave some of his habits behind—all their activities will be directed towards a certain goal and that he won't see sunsets，sunrises，won't feel rain for 18 months.

　　After 250 days，three of the astronauts will simulate landing on Mars.The other three will wait for them—in the mock spacecraft—for a month.All communication with Earth will be via e­mail and will have as much as a 40­minute delay，like on a real Mars mission.

　　Suvorov is a physician.He and other scientists will monitor the astronauts.“This experiment is unique because the six persons will be isolated for a long period of time，” noted Suvorov.“They will have to make decisions on their own and only then report to the Earth，and the Earth will tell them whether they did the right thing or not.”He says the experiment will pave the way for a real Mars journey later this century.“We are going to determine how much food and other products of daily use are needed，and how people of different cultures，of different training can find common language and work on performing their tasks，” added Suvorov.
