in the process, apart from the application fee, which varied as a function of each applicant's country GDP. Lansdorp acknowledges a "gamification" point system but denies that selection is based on money earned. Roche also stated that if paid for interviews, they are asked to donate 75% of the payment to Mars One. This was confirmed by Lansdorp. Round 3: Group challenges The company had intended that the regional selection may be broadcast as a reality television show documenting group challenges, but no deal was reached with TV producers. The audience was to select one winner per region, and the experts could select additional participants, if needed, to continue to the international level. Of the 100 candidates, 40 individuals were to be chosen through an interview process. Round 3 would take place after enough funding is secured for an "Earth-based simulation outpost." Round 4: Isolation The remaining 40 candidates would be spending nine days in an isolation unit. The candidates are observed closely to examine how they act in situations of prolonged close contact with one another. It takes a specific team dynamic to be able to handle this, and the goal of this selection round is to find those that are best suited for this challenge. After the isolation round, 30 candidates would be chosen to undergo in a Mars Settler Suitability Interview. Round 5: Mars Settler Suitability Interview The Mars Settler Suitability Interview would have measured suitability for long-duration space missions and Mars settlement, and would last approximately 4 hours. 24 candidates would be selected after the interview and would be offered full-time employment with Mars One. Astronaut training From the previous selection series, six groups of four were to become full-time employees of the Mars One, after which they were to train for the mission. An MIT team noted that since the company is not developing the technology needed, it is unclear what the astronauts would be training for. Mars One has stated that the teams selected were going to undergo a battery of training, ranging from psycho-social skills to engineering and scientific observation. Revenues and investment Mars One funding came from astronaut application fees, donations, undisclosed private investment, intellectual property (IP) rights, and mostly, the potential sale of future broadcasting rights. Over three-quarters of the funds reportedly went to concept design studies. Mars One states that "income from donations and merchandise have not been used to
