Shenzhou XIII taikonauts' six-month stay at the Tiangong space station is wrapping up. Now they face one last test of their scientific and space travel skills—returning home safely. What needs to be done before leaving space station in mid-April?
Besides their personal (belong), astronauts also need to "pack" experimental data and samples, so they can be further researched on Earth. And they have to tidy up a large number of materials, (include) goods on the Tianzhou 3 cargo (货物) spacecraft.
Since the space station has no room service, the three astronauts need to "clean the house"(they). The waste is then put into the orbital module, which burns as it re-enters Earth's atmosphere.
They also have to put all equipment place correctly since there will be a gap of more than one month the astronauts of Shenzhou XIV enter the space station. The crew members need to make sure some items, such as gym equipment, (fix) to the walls to avoid floating and slipping.
Astronauts experience microgravity (微重力) for long periods of time during their stays on the space station, has an effect on their bodies. This includes a loss of fluid, muscle atrophy as well as bone loss. (ensure) their safe and sound return, the three taikonauts have been doing physical exercises to train their muscle for the return to Earth. (base) on their in-orbit physical examinations and data, experts have customized (定制) exercise plans for each of them.
Just like a house that will be empty for a long time must have its water and power switched off, taikonauts need to check everything before they leave.
