A photography exhibit detailing the training of American astronauts, along with spacefarers from China and Russia, was recently on display at the London Art Fair. In addition to snazzy spacesuits and a mission control center that still looks like NASA's old room, the participants (Like the one in the lower right of the photo above) are made to mobilize in a barren, Mars-like location at the Mars Desert Research Station in Utah.

(Yes, I know, that's Furnier, not Fournier.)
The Mars Desert Research Station is perfect for training astronauts and cosmonauts and stellarnauts of all kinds. Except for the gravity, the air, the moisture, the nearby help, the warmth, and the lack of deadly solar radiation, it is exactly like Mars.
