Mars One, led by Dutch entrepeneur Bas Lansdorp, is a non-profit organization that plans to establish a permanent human colony on Mars by 2023. The first flight with a crew of 4 astronauts will depart in September 2022 for a one-way mission.
The first round of the Mars One Astronaut Selection Program began on April 22 and closed on August 31, 2013. In just 4 months, Mars One received 202,586 applications from 14 countries to become the first human settlers on the red planet.
