Astronaut:
Astronauts, or astronauts, are full-name astronauts, referring to people who take space flight as their profession or have flown in space.
The criteria for determining space flight are not completely uniform. In the United States, people who travel above 80 kilometers (50 miles) above sea level are called astronauts. The space flight defined by the International Aviation Federation (FAI) needs to exceed100km.
By April 18, 2004, 440 people had spent an astronaut day in space (defined by the United States) and enjoyed 98 astronaut days through spacewalking. According to the definition of the International Aviation Federation, only 434 people meet the requirements.
The astronauts who went into space came from at least 32 countries. In Hong Kong and Southeast Asia, astronauts are also called astronauts. As of 20 13, only the former Soviet Union/Russia, the United States and China have the ability to launch manned space missions. Astronauts from other countries need to cooperate with the above three countries to complete manned space missions.
Since the first human flight in 196 1, astronauts from 38 countries have successively flown.
