If you're one of the (uh, lucky?) people chosen for the program, you'll move to the United States to spend the next seven years as a full-time, salaried employee of Mars One. Nine months of each year will be spent learning dentistry, emergency medicine, general medicine, engineering, biology, mechanics—anything you might need to know on an inhospitable planet with a population of four. The other three months of each year will be spent in a Mars habitat mock-up, complete with a 40-minute communication delay to the outside world and simulated emergencies. The hardest thing they'll face during the simulation? A broken toilet, Lansdorp says. "That's when people get out of control."
