Humans might not have landed on Mars yet - but you can already apply to be one of the first to colonise its surface.

Only problem? You'll never come back.

Mars One, a Netherlands-based non-profit, has the lofty aim of reaching our nearest neighbouring planet in 2023.

On Wednesday it released its basic requirements for astronauts, ahead of a (ahem) televised selection process.

Yes, this is 2001: A Space Odyssey meets the X-Factor.

The idea is to find four people to go to Mars - via an "unprecedented" media spectacle - and use the show itself to fund the actual mission.

The four colonists will theoretically go to Mars in 2023, after eight robotic missions between 2016 and 2021 to establish a habitable settlement. New members will arrive every two years. None will ever return to Earth.

All you have to do to meet the requirements to apply are be over 18 years old.

Among the criteria upon which you'll be judged are your intelligence, mental and physical health and your dedication to the idea.
