China Shenzhou Hong Kong astronaut Tiangong launch sent the Shenzhou 23 crew to the Tiangong space station, the mission lifted off from the Jiuquan Satellite Launch Center aboard a Long March 2F rocket at 11:08 p.m. local time, according to state media.
The three crew members are commander Zhu Yangzhu, pilot Zhang Zhiyuan and payload specialist Lai Ka-ying, who is identified by Chinese authorities as Li Jiaying, AP reported, and is the first person from Hong Kong to fly on a Chinese crewed mission.
State media and published reports say the new trio will begin a planned six month rotation aboard Tiangong, and that one member of Shenzhou 23 will remain for an extended, yearlong stay to study human adaptability in long duration flight, an objective described by state media.
Mission Context And Program Implications
The launch follows an emergency-impacted sequence of recent Shenzhou flights, during which a damaged return vehicle prompted an uncrewed lifeboat mission to the station, and the current crew used an alternate spacecraft for return, as reported in coverage of the program.
China Manned Space Agency and state media say the yearlong plan is linked to an upcoming crew rotation that will include an international visit, with one short-duration visitor from Pakistan flying later and swapping places with a Shenzhou 23 astronaut, leaving a Shenzhou 23 crew member aboard for roughly a year.
Reports in the international press place the launch in a wider context of Chinese plans for a crewed lunar landing by 2030, noting the flight will execute an autonomous rapid rendezvous and docking test with the core module in preparation for more complex missions, AP and ABC reported.
State media and other outlets also say the crew will carry out dozens of science and application projects, studying radiation exposure, bone density loss and psychological stress on long missions, and that recent missions have carried biological experiments including human stem cell samples to Tiangong, according to Reuters and ABC.
Chinese authorities have not announced which Shenzhou 23 astronaut will serve the full year, and mission officials describe the extended stay as a step to chart human performance limits in longer missions while the country advances hardware and procedures for future lunar exploration.
