China launched (发射) the Shenzhou ⅫⅠ spaceship on October 16, 2021. Zhai Zhigang, Wan Yaping and Ye Guangfu will spend six months inside the Tiangong space station. They carried out the lastest Shenzhou ⅫⅠ mission. It will be the longest space journey by Chinese astronauts. Have you ever dreamed of becoming 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 lungs 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.
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 backup (预备的) astronaut. It's very difficult. For example, you need to build your muscles as strong as professional athletes by running, swimming and doing pull-ups. You will also wear a 200-kilogram suit and so tasks underwater for six or seven hours without eating or going to the toilet. This is like doing tasks during a spacewalk.
Learn science. Knowledge is important as well. Astronauts take 60 courses to get ready for a mission, including math, English, spacecraft design, physics and so on. So they will know what to do when emergencies (紧急情况) happen during the mission.
How long will the astronauts stay in space this time?
