An anonymous reader writes "lacing humans on Mars will be an extraordinary feat in itself, not to mention even living in such a harsh environment. To help train future astronauts to sustain life on Mars, the Mars Society has created the Mars Desert Research Station. The Mars Desert Research Station (MDRS) is one of four planned simulated Mars habitats (or Mars Analogue Research Station Programme) maintained by the Mars Society. Crews sign up for two week shifts during the winter months (it's too hot in the summer for pleasant simulation). Crews are not paid during their time at the station, but do get valuable experience."
