Humans could only survive on Mars for 68 days

Humans could only survive on Mars for 68 days according to a new study which throws doubt on ambitions to colonise the Red Planet.

Scientists at the Massachusetts Institute of Technology (MIT) concluded that with current technology a permanent settlement on Mars is "not feasible".

They analysed the Dutch-based Mars One project which is aiming to colonise the planet starting in 2024.

Mars One wants to send a group of people on a one-way trip and film the project for a reality television show.
