What does "practice 10" look like? Like a warhead! Chemical batteries are mainly used.
What's the use of "practice 10" This temporary space laboratory will use special environments such as space microgravity to complete 19 experiments in six fields: microgravity fluid physics, microgravity combustion, space materials science, space radiation effect, gravity biological effect and space biotechnology in 15 days.
Can I go home after practicing ten? Sure! This is a recoverable satellite, and the return capsule will bring the experimental samples back to Earth.
