Timeline of space travel by nationality

Since the first human spaceflight by the Soviet Union, citizens of 49 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 8 of 49 countries have been represented by female "first flyers". Only three nations have launched their own crewed spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts. Twenty-eight "first flights" occurred on Soviet or Russian flights while the United States carried nineteen.
