More than 600 people in China have applied for a one-way ticket to live on Mars in dome-shaped space capsules.
The Mars One project is looking for volunteers to live on the Red Planet and will choose two men and two women to fly there by 2023.
It only costs £7 to sign up to Mars One and hundreds of Chinese have already put their names down.
The project is the brainchild of Dutch entrepreneur Bas Lansdorp who hopes to put man on Mars in at least 10 years.
