"We're not going to Mars to die β€” we're going to Mars to live," said Mars One CEO Bas Lansdorp. How long a life would make the trip worthwhile? Panelists at the Million Martian Meeting held in D.C last month talked about their willingness to risk it all for a (very) short time on Mars. Leila Zucker, 45, a married emergency room doctor, said "said she would take a 50-50 chance of surviving two years, or a 1-in-100 chance for surviving 20 years. "None of us are planning to die," she said, "but we all recognize we could."

What if the pioneers would only last one year on Mars? It would depend how much she could accomplish in that year. "That year has to count β€” you don’t get my life for nothing," Zucker said. What would she miss most? "I’d miss Ron, my spousal-unit of 21 years (who by the way is the one who told me about Mars One)," Zucker said.

165,000 people sent in applications for a one-way trip to Mars. Most applicants, 80%, are male.
