List of space travelers by nationality
From Wikipedia, the free encyclopedia
Countries (and successor states) whose citizens have flown in space as of September 2019.
The criteria for determining who has achieved human spaceflight vary. The FAI defines spaceflight as any flight over 100 kilometres (62 mi). In the United States, professional, military, and commercial astronauts who travel above an altitude of 80 kilometres (50 mi) are awarded astronaut wings. The majority of people who have flown into space have done so by entering Earth orbit. This list includes persons meeting all three criteria, in separate subdivisions.
The flags indicate the space traveler's nationality at the time of their flight or flights. In cases of dual citizenship, the space traveler is listed under their primary residence. A secondary list appended to the entry for the Soviet Union shows the birth countries of space travelers not born in Russia. A similar list after the entry for the United States shows the birth countries of space travelers who are or were citizens of the U.S. but were born elsewhere. Flags shown in the secondary lists are those in use at the time of the space travelers' birth.
Names in italic are space travelers who are not part of any national astronaut program or astronaut corps (Toyohiro Akiyama, Helen Sharman, the Space Adventures customers and the sub-orbital SpaceShipOne and Blue Origin pilots).
Statistics
As of May 2022, people from 44 countries have traveled in space.[1] 622 people have reached Earth orbit. 628 have reached the altitude of space according to the FAI definition of the boundary of space, and 565 people have reached the altitude of space according to the American definition. 24 people have traveled beyond low Earth orbit and either circled, orbited, or walked on the Moon.

Russia and the Soviet Union
The Soviet space program came under the control of the Russian Federation in December 1991; the new program, now called the Russian Federal Space Agency, retained continuity of equipment and personnel with the Soviet program. While all Soviet and RKA cosmonauts were born within the borders of the U.S.S.R., many were born outside the boundaries of Russia, and may be claimed by other Soviet successor states as nationals of those states. These cosmonauts are marked with an asterisk * and their place of birth is shown in an appended list. All, however, claimed Soviet or Russian citizenship at the time of their space flights.
