Under the established standard set by NASA, what is required in addition to flying above the Kármán line for an individual to be considered an astronaut?
Answer
Participation must be integral to the flight’s success, like a mission specialist.
The traditional definition of an astronaut, largely set by agencies like NASA, centers heavily on professional contribution and mission criticality, rather than just reaching a certain altitude. While crossing the Kármán line is necessary, the crucial differentiator is the role played on the mission. NASA expects its astronauts to be professional astronauts, mission specialists, or individuals whose presence and actions are integral to the successful completion of the flight objectives, which often involve complex operations, piloting, or scientific experimentation. This stands in stark contrast to the role of a space tourist who might merely be a passenger.
