Human spaceflight programs

Résumé
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. The age of manned rocket flight was initiated by Fritz von Opel who piloted the world's first rocket-propelled flight on 30 September 1929. All space flights depend on rocket technology; von Opel was the co-designer and financier of the visionary project. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries (Soviet Union/Russia, United States and China) and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies (Scaled Composites and Blue Origin) had launched humans on a suborbital trajectory. The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale defines spaceflight as any flight over . In the United States professional, military, and commercial astronauts who travel above an altitude of are awarded the United States Astronaut Badge. This article follows the FAI definition of spaceflight. List of government space agencies#List of space agencies with human spaceflight capability Programs in this section are sorted by the years when the first successful crewed spaceflight took place. The Vostok program was a project that succeeded in putting a person into orbit for the first time. Sergei Korolev and Konstantin Feoktistov began, in June 1956, crewed spacecraft research. The program developed the Vostok spacecraft from the Zenit spy satellite project and adapted the Vostok rocket from an existing ICBM design. Just before the first release of the name Vostok to the press, it was a classified word. By August/September 1958 a division had been formed devoted to producing the first Vostok craft.
