Mars One

Have you ever wanted to live on Mars? Well, 1,058 people are finalists in a worldwide contest for the chance to live on Mars. The project for a permament human settlement on Mars is organized by the Dutch non-profit Mars One. The effort is backed by several aerospace companies, including SpaceX and Lockheed Martin.

How would you like to go to Mars? I'm sure most of us would say "Heck ya, sign me up," but there's a catch. It's a one way flight so once you leave, there's no guarantee that you will ever be able to return to Earth.
