Mars One is a private non-profit organisation that plans to establish a permanent human colony on Mars by 2025. The project leader, Dutch entrepreneur Bas Lansdorp, announced plans for the Mars One mission in May 2012.
Mars One selected a second-round pool of astronaut candidates early in 2014 of 1058 people from a larger number of some 200,000 who showed interest on the Mars One website. The second-round pool was narrowed down to 660 candidates who were recently interviewed online. On 16 February this year, 100 Round 3 finalists from around the world were announced.
