Mars One is a private spaceflight project to establish a permanent human colony on Mars.
Announced in June 2012, the plan is to send a communication satellite and path finder lander to the planet by 2016 and, after several stages, land four humans on Mars for permanent settlement in 2023. A new set of four astronauts would then arrive every two years.
Mars One became a not for profit foundation (under Dutch law) in early October 2012.
