The Mars Society is looking for a few good men – and women – to spend four months holed up in an artificial igloo or tromping around the Canadian Arctic in bulky faux spacesuits. This won’t be an extended vacation, or a reality-TV plotline. For rocket scientist Robert Zubrin, president of the Mars Society, next year’s exercise on Devon Island will be an experiment in the exploration process – a test that could help smooth the path to Mars. It’s been a couple of months since Zubrin first announced the plans for a four-month simulated Mars mission on Devon Island in Canada’s Nunavut territory, just 900 miles (1,440 kilometers) from the North Pole. Now he and other mission planners are ready to sign up a volunteer crew of seven who will operate from the Mars Society’s Arctic habitat from May to September next year.
