Mars One applicants come from over 140 countries; the largest numbers are from the United States (24%), India (10%), China (6%), Brazil (5%), Great Britain (4%), Canada (4%), Russia (4%), Mexico (4%), Philippines (2%), Spain (2%), Colombia (2%), Argentina (2%), Australia (1%), France (1%), Turkey (1%), Chile (1%), Ukraine (1%), Peru (1%), Germany (1%), Italy (1%) and Poland (1%).

From this applicant pool, the Mars One Selection Committee will select prospective Martian settlers in three additional rounds spread across two years. By 2015, six-ten teams of four individuals will be selected for seven years of full-time training. In 2023, one of these teams will become the first humans ever to land on Mars and live there for the rest of their lives.

Each Round 1 applicant is now being screened by the Selection Committee, which is expected to take several months. Candidates selected to pass to the next round will be notified by the end of 2013. The second round of selection will start in early 2014, where the candidates will be interviewed in person by the Mars One Selection Committee.

Aspiring martians who have missed Round 1 or could not meet the age restriction can join subsequent Astronaut Selection Programs. Mars One will commence regular recruitment programs as the search for follow-up crews continues.
