The Shenzhou XX crew is conducting China's 15th manned spaceflight and will become the ninth group of residents aboard the Tiangong, which is currently the only operational space station independently run by a single nation.

During their six-month orbital stay, Chen Dong and his teammates will perform various tasks such as conducting scientific experiments and technological demonstrations, performing spacewalks to install space debris shielding equipment, experimental instruments and other external devices, retrieving devices from outside the space station, and engaging in science lectures and other activities for public benefit.
