This return ended the Shenzhou XIII astronauts’ six-month space mission. It also marks a major (重大的) breakthrough for China’s efforts in space. In order to return home safety, they did a lot of preparation before leaving the space station. If you are coming home after a long journey, you have to pack up. For astronauts in space, besides their personal belongings, they “packed” experimental data (数据) and samples, so they would be further researched on Earth. The astronauts had to tidy up a large number of materials, including goods on the Tianzhou 3 cargo (货物) spacecraft, according to Zhong Weiwei, a researcher at the China Astronaut Research and Training Center. Since the space station had no room service, the three astronauts needed to “clear the house” themselves. They collected a great amount of waste. This included leftover foods, sanitary (卫生) waste and waste from in-orbit experiments. The waste was then put into the orbital module (轨道舱), which burnt up as it reentered Earth’s atmosphere. They also had to put all equipment in place correctly since there would be a gap of more than one month before the astronauts of Shenzhou XIV enter the space station, according to Zhong. They needed to make sure some items, such as gym equipment, were fixed to the walls to avoid floating and slipping (滑落). Astronauts experienced microgravity for long periods of time during their stays on the space station, which had an effect on their bodies. This included a loss of fluid (体液) muscle atrophy (萎缩) as well as bone loss. To ensure their safe and sound return, the three astronauts had been doing physical exercises to train their muscles for the return to Earth. Based on their in-orbit physical examinations and data, experts had customized (定制) exercise plans for each of them to ensure a safe landing.
