Crew in Moscow to Simulate Part of a Flight to Mars - NYTimes.com: "On Tuesday, six people will be voluntarily locked into a cloister of cramped, hermetically sealed tubes woven inside a Moscow research facility the size of a high school gymnasium. They will eat dehydrated food, breathe recycled air and be denied conversation with practically everyone else but one another.

And they must stay inside for 105 days.

In a small step in the direction of Mars, the international crew is embarking on a simulated flight to the planet to test the limits of human tolerance for the isolation and monotony of interplanetary travel."
