On June 5,Chen Dong, Liu Yang and Cai Xuzhen—the astronauts of Shenzhou-14 spaceship—got into China's Tianhe space station, starting their journey in space. They returned back to Earth and successfully landed at the Dongfeng landing site on December 4. Do you want to be an astronaut like them? How did they get there?
Health is important.
To be an astronaut, you need to be very healthy. Good eyesight, a strong heart and healthy lungs(肺)are important. You'd better not have other small problems. For example, a decayed tooth(龋齿) could get worse in space and bring trouble to astronauts. You can't have scars(伤疤) , either. They may split(裂开）in space, as Pang Zhihao, a space scientist, told the Beijing Morning Post.
Become stronger with hard training.
In China, you must be a great pilot before you can be an astronaut. You must fly more than 600 hours without accidents. You'll start training when you become a backup(预备的) astronaut. It's very difficult. For example, you need to build your muscles(肌肉) as strong as possible like professional athletes by running, swimming and doing pull-ups.
Learn science.
Knowledge(知识) is important as well. Astronauts take 60 courses to get ready for a mission, including math, English, spacecraft design, physics and many more. So they will know what to do when something dangerous happens during the mission. They can also do scientific experiments (实验) in space.
