How Do Astronaut Candidate Profiles Differ From Airline Pilot Profiles?

Abstract

Sixteen years after the second Europe-wide astronaut selection campaign, the European Space Agency started the third campaign by putting out a call for new astronauts in 2008. Due to extreme environmental conditions, expensive scientific experiments, and high public interest, not only are the psychological requirements on a high level, but they are also wide in variety: Besides cognitive and psychomotor requirements, greater importance than in comparable campaigns was put on personality and behavioral aspects, especially regarding interpersonal aspects. The psychological selection was conducted in two steps: Phase 1 concentrated mainly on performance tests and Phase 2 focused on personality and interpersonal behavior. Out of the 902 tested candidates, 46 fulfilled the psychological requirements. Significant differences were found between the astronaut candidates and the general population as well as airline pilot candidates.
