Mars One was a private organization founded in 2012 with the goal of establishing a human settlement on Mars. The project aimed to send the first crewed mission to the planet by the mid-2020s, using a one-way trip model. This meant that astronauts would live and work on Mars permanently, contributing to the development of a sustainable colony. The initiative gained significant attention and attracted thousands of applicants for its astronaut selection process. However, it faced numerous challenges, including funding issues and technical feasibility concerns, leading to skepticism about its ability to achieve its ambitious goals.
