China is set to launch the Shenzhou XXI spacecraft on Friday night, marking a significant milestone in its space exploration program. The mission, led by Senior Colonel Zhang Lu, will transport three astronauts to the Tiangong space station for a six-month stay. The launch is scheduled for 11:44 pm from the Jiuquan Satellite Launch Center in Inner Mongolia, utilizing a Long March 2F carrier rocket. The crew includes Major Wu Fei, the spaceflight engineer, and mission payload specialist Zhang Hongzhang, both of whom are embarking on their first space mission. The Shenzhou XXI spacecraft will employ a rapid autonomous rendezvous-docking mode to connect with the Tianhe core module of the Tiangong space station, a process expected to take approximately three and a half hours. This mission will facilitate the crew exchange with the current occupants, Senior Colonel Chen Dong, Colonel Chen Zhongrui, and Colonel Wang Jie, who have been aboard the station since late April. The Tiangong space station, completed in late 2022, remains the only independently operated space station in orbit, positioned approximately 400 kilometers above Earth. This launch underscores China’s growing capabilities in space technology and its commitment to maintaining a continuous human presence in space.
