US space agency NASA is looking for volunteer “Martians”. The conditions at the test site in Houston, Texas are intended to simulate life on Mars as closely as possible.

With this long-term project, NASA wants to find out what future astronauts need to survive a real Mars mission. Applicants must meet some criteria: Master's degree in a scientific field, including engineering, life sciences, natural sciences, computer science or mathematics. Two years of professional experience or at least 1,000 hours of flight time as a pilot in a jet aircraft. Age between 30 and 55 years.
