The project, which lasts for 18 months, is designed to try and simulate a mission to mission to Mars, completely isolated and cut off from the outside world, with a '20-minute, one-way time-delay in communications to mirror the real lag in sending messages over the vast distance between Mars and Earth.' They also have limited consumables, with everything required being loaded onboard from the start. You can follow developments via the blog, or the twitter feed of Diego Urbina, one of the would-be cosmonauts."
