On October 16, 2021, Shenzhou XIII carried three Chinese astronauts (宇航员) into space (太空). They are Zhai Zhigang, Wang Yaping and Ye Guangfu. They will live and work in Tiangong’s core module (核心舱), Tianhe, for six months. During their stay, they have many things to do. They will do scientific experiments (科学实验) and spacewalks.
On November 7, 2021, Wang Yaping became China’s first woman to walk in space! “I feel great!” Wang said when she came out of Tiangong space station. Wang, 41, together with astronaut Zhai Zhigang, had a 6.5-hour spacewalk. Wang also became a “space teacher” and gave a lesson to students on Earth.
One other special thing is that the astronauts will spend the Spring Festival in space for the first time. What will they do? We can see them on TV later and find out!
