Alex Kirk. The Mars Society Frequently Asked Questions. 8 April 2008: “There are many of people who, if told that they could be part of an expedition to Mars only if they abandoned all hope of returning to Earth, would jump at the chance. Thousands more would sign up for a trip where their chances of returning were only 50/50. Looking back over time, people have always been willing to risk their lives for things they care about, for great missions of exploration. More importantly, why should people who will be staying safely here on Earth deny the people who wish to take that chance the opportunity, just because the explorers might die?”
