A few months before he died, Carl Sagan recorded a message of hope to would-be Mars explorers, telling them: "Whatever the reason you're on Mars is, I'm glad you're there. And I wish I was with you."
On Monday, 17 years after the pioneering astronomer set out his hopeful vision of the future in 1996, a company from the Netherlands is proposing to turn Sagan's dreams of reaching Mars into reality. The company, Mars One, plans to send four astronauts on a trip to the Red Planet to set up a human colony in 2023.

Interesting article. It says that people who go will never return to Earth, because their bodies will have adapted to Martian conditions.
That doesn't seem to be such a problem. History is full of people making huge migrations to new environments and never returning to their homeland.
