Looking for an out-of-this-world experience? Mars One, a non-profit agency, is accepting applications for astronauts  to help build the first settlement on the red planet in 2023.
Astronauts will undergo a whopping eight years of training before being deployed to Mars  to build a sustainable life there, the company said. While you don't have to have an advanced degree in science, Mars One is looking for people with intelligence, good mental and physical health, and dedication.
According to its website, Mars One expects the mission to cost around $6 billion.Flickr User Andy Z ]
