The United States has seen several space programs since the beginnings of spaceflight. The criteria for what constitutes spaceflight vary. In the United States, professional, military, and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings. The Fédération Aéronautique Internationale defines spaceflight as any flight over 62 miles (100 km). This article follows the US definition of spaceflight.
