It sounds like a science-fiction fantasy, but the company Mars One says it's for real—and that it will really establish a settlement on the planet Mars by 2023.
The privately financed Dutch company has a plan. All it needs is a lot of cash, equipment and four Mars-bound astronauts who are willing to take a one-way trip to the red planet.
The idea is to first send rovers, which will stake out a good site for a settlement and then build out living units. In 2022, the crew will take a "transit habitat" for the seven-month trip to Mars and settle in to their new home. The intention is that the crew will live on the planet for the rest of their lives. Every two years after that, another group will join the settlement to populate the colony.
