Timeline of space travel by nationality – Wikipedia

Since the first human spaceflight by the Soviet Union, citizens of 44 countries have flown in space. For each nationality, the launch date of the first mission is listed. The list is based on the nationality of the person at the time of the launch. Only 4 of the 44 "first flyers" have been women (Helen Sharman for the United Kingdom in 1991, Anousheh Ansari for Iran in 2006, Yi So-yeon for South Korea in 2008, and Sara Sabry for Egypt in 2022). Only three nations (Soviet Union/Russia, U.S., China) have launched their own crewed spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts. Twenty-seven "first flights" occurred on Soviet or Russian flights while the United States carried sixteen.

Note: All dates given are UTC. Countries indicated in bold have achieved independent human spaceflight capability.

The above list uses the nationality at the time of launch. Lists with differing criteria might include the following people:

The Soviet Union's Yuri Gagarin, the first person in space (1961)

Alan Shepard from the United States of America, the second nation to send a person into space (1961)

Mirosaw Hermaszewski of Poland, the first Polish national in space (1978)

Sigmund Jhn of East Germany, the first German in space (1978)
