It verified the last few key technologies required for the construction and operation of the space station, laying an important foundation for China to build the "Tiangong".
The Shenzhou 13 spacecraft is the last spacecraft launched before the Chinese space station enters the construction stage. It has its own "magic" and "unique" features. Radial rendezvous and docking and 180 days of on-orbit flight are the keys to achieving simultaneous multi-person duty and long-term care of China's space station. Only by mastering them can China have an indestructible "Tiangong".
Another key technology that the Shenzhou 13 spacecraft needs to verify is its six-month long-term orbital flight, which will set a record for the longest space stay for Chinese astronauts.
Main purposes:
First, carry out key technology tests for space station assembly and construction such as robotic arm-assisted module transposition and manual remote operation.
The second is to conduct 2-3 extravehicular activities and install large and small robotic arm dual-arm combination adapters and suspension devices to prepare for subsequent space station construction tasks.
The third is to further verify the health, life and work support technology for astronauts staying in orbit for 6 months.
The fourth is to conduct scientific and technological experiments and applications in the fields of aerospace medicine and microgravity physics, and carry out diversified science education activities.
The fifth is to comprehensively assess the functional performance of each system in the project to perform the space station mission, as well as the matching between systems.
