Cabin life aboard the wooden spaceship

Urbina was joined by Russia's Alexandr Smoleevskiy on the initial "Marswalk", which lasted an hour and 12 minutes. The next walk will see Smoleevskiy and Wang Ye of China leave Urbina behind in the lander; the final walk will be carried out by the original duo on 22 February.

Life inside the wooden spaceship of tomorrow.

Meanwhile the men's comrades Romain Charles, Alexey Sitev and Sukhrob Kamolov remain "in orbit" downstairs in the main spaceship simulator unit. Following pretend blastoff on 23 February, the "Marswalker" group will simulate an orbital rendezvous and docking before being allowed back into the main complex on 27 February. Then the crew will load all their rubbish into the "lander" and shut the door on it: the ESA says that it would then be discarded on a real flight.

Another eight-month "interplanetary" odyssey will follow, which according to the space agency may be the toughest bit of the project:

The most difficult but the most interesting part of this psychological study of long flights is still ahead: the crew is now faced with another monotonous ‘interplanetary cruise’ without a highlight like the Mars landing to look forward to.

That said, the 20-minute latency which has been gradually introduced into all comms from inside to outside the Mars500 complex will then be decreasing, and it could be that the prospect of getting out will be at least as attractive as that of having a bimble about in an indoor sandpit has been.

“The crew is highly motivated and performing very well,” comments Jennifer Ngo-Anh, ESA's Mars500 honcho.

“The science community is very pleased with the quality of the material but, as this is a long experiment, we have to wait for the results until their ‘arrival’ at Earth. “At this point, everything looks very good.”
