On May 24, 2026, from Launch Pad No. 43/91 at the Jiuquan Cosmodrome in northwestern China, the Changzheng-2F/G (Y23) carrier rocket successfully launched the Shenzhou-23 spacecraft with three taikonauts aboard. Following a flawless separation from the rocket, the spacecraft entered Earth orbit and proceeded to dock with the national space station, Tiangong. This orbital rendezvous and docking maneuver took approximately 4 hours to complete. According to official reports, all crew members are in excellent condition, and both the launch and docking phases have been declared complete successes.
Zhang Jingbo, an official spokesperson for the China National Space Administration (CNSA), revealed the extensive scientific program for Shenzhou-23 during a press conference held prior to the launch. The taikonauts are tasked with undertaking over 100 novel scientific and applied projects across cutting-edge fields such as space biology, materials science, aerospace medicine, microgravity fluid physics, and new technologies.
Among the key and most significant research endeavors are:
The establishment of a space-based embryonic research system: Scientists aim to investigate the potential for life development in space, spanning from lower vertebrates to higher mammals. To achieve this, experiments will be conducted in orbit using embryos from mice and fish, as well as artificially derived embryos created from stem cells.
Space materials science: The crew will focus on the production of advanced materials possessing unique properties. These include highly efficient permanent magnets composed of rare-earth alloys and lightweight, high-entropy alloys.
Testing the future of energy: A new type of space-based battery will undergo verification in orbit. The results from this test are intended to inform future major upgrades to the space station’s functionalities.
The Shenzhou-23 mission will also mark a critical milestone for Chinese space medicine, as one of the taikonauts will spend an entire year in orbit. This year-long mission is designed to assist researchers in understanding the adaptive limits of the human body and to compile a comprehensive atlas detailing the changes occurring within its systems during extended stays in space.
In addition to scientific investigations, the crew is scheduled to carry out a substantial number of operational tasks. These include extravehicular activities (EVAs), the transfer of incoming cargo, the installation of external equipment, the deployment of payloads, and their subsequent retrieval back to the spacecraft.
