Soon, Big Brother ... on Mars!
A dutch start-up company is aiming to beat Nasa by sending the first humans to Mars - and film it all as a reality show.
But it's a one-way trip.
The start-up, Mars One, says it is serious about landing four astronauts on Mars by 2023, seven years before the US space agency's target, and plans to start searching for volunteers next year.
The man behind Mars One, mechanical engineer Bas Lansdorp, estimates the cost at $6-billion.
His plan is to televise the selection and training of the astronauts, and their space journey and lives on Mars - just like Big Brother.
