Six volunteers were locked away last week in Moscow as part of the Mars500 project, a 520-day isolation simulation that will test what it would be like to spend more than a year traveling between the Earth and Mars.

We've previously discussed just what scientists at the European Space Agency are hoping to learn from the experiment. We'll check back in on Mars500 a bit later when data has started to emerge, but for now here's Ralf Heckel of Germany's International Space Institute and Pavel Sharov (in an oh-so-fashionable black T-shirt ensemble) of the Russian organization Novosti Kosmonavtiki explaining what this is all about.
