Spaceflight participant

Spaceflight participant (Russian: участник космического полета, romanized: uchastnik kosmicheskogo polyota) is the term used by NASA, Roscosmos, and the Federal Aviation Administration (FAA) for people who travel into space, but are not professional astronauts.

While the term gained new prominence with the rise of space tourism, it has also been used for participants in programs like NASA's Teacher in Space and astronauts designated by inter-government agreements like the Angkasawan program and the Korean Astronaut Program.

Other terms used for space travelers who are not career astronauts include NASA's Payload Specialist and the RKA's Researcher-Cosmonaut.
