Living like Martians for a week has stoked the dreams of Mars’ scientific zealots who believe astronauts could walk on the Red Planet within 10 years. Members of a hi-tech crew are in Toronto this week after returning from a Mars-like research station in the Arctic where they’ve been trained for an imaginary mission to Mars. “We believe there are hundreds of millions of people around the world who want to see the exploration of Mars,” said Dr. Robert Zubrin, president of the Mars Society, the group that organized the expedition. “And doing it is completely political. From a technical point of view, we could launch to Mars in 2008.”
