Welcome home! On April16, astronauts (宇航员) Zhai Zhigang, Wang Yaping and Ye Guangfu safely came back to Earth from the Tiangong space station.
The three astronauts stayed in the space station for half a year. Wang Yaping was the first Chinese female (女性) to do a space walk. The astronauts in space gave two science classes to students on Earth. When the Shenzhou XII came back from the space station in 2021, it took about twenty-eight hours. This time, Shenzhou XIII only took nine hours to return!
The astronauts felt good after landing (着陆) , but they still needed to sit on chairs. In the next few months, they will take a check-up (检查) and have a good rest. They will get used to (习惯) Earth's gravity (重力) this way.
