List of space travelers by nationality explained

The criteria for determining who has achieved human spaceflight vary. The (FAI) defines spaceflight as any flight over 100km (100miles), while in the United States, professional, military and commercial astronauts who travel above an altitude of 50miles are awarded astronaut wings. The majority of people who have flown into space have done so by entering Earth orbit. This list includes people meeting all three criteria, in separate subdivisions.

The flags indicate the space traveler's nationality at the time of their flight. 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 were citizens of the US 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

, people from 47 countries have traveled in space.^[1] 644 have reached the altitude of space according to the FAI definition of the boundary of space,^[2] and 681 people have reached the altitude of space according to the USAF definition and 610 people have reached Earth orbit.^[3] 24 people have traveled beyond low Earth orbit and either circled, orbited, or walked on the Moon.

Of the 44 countries whose citizens have traveled into Earth orbit, 25 have flown a single space traveler, and four others (Belgium, Bulgaria, the Netherlands, and the United Kingdom) have flown two each. 94% of all space travelers have been contributed by the following eight nations:

¹ Includes 70 male and 2 female Soviet cosmonauts.
² Includes both national space programme activity and European Space Agency participation.
³ Includes astronauts from the Federal Republic of Germany and the German Democratic Republic.

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 USSR, 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.
