Shenzhou-18 Crew: Experiments & Maintenance Work | China Space Station
The Shenzhou-18 astronauts, who have been in orbit for about four months, have conducted a series of space science experiments while performing a variety of tasks, including environmental monitoring and equipment maintenance, on China's Tiangong space station, as shown in recently released footage from the China Manned Space Agency (CMSA).
The three Shenzhou-18 crew members—Ye Guangfu, Li Cong, and Li Guangsu—who boarded the Tiangong space station in late April 2024, used an experimental information management computer and specialized testing software to conduct assessments of their emergency decision-making abilities and in-orbit emotional states. Ground-based researchers will analyze the collected data to evaluate the astronauts' decision-making capabilities and emotional responses, aiming to understand the underlying patterns.
In the field of aerospace medicine, the crew has conducted eye-hand coordination tests, electrical acupoint stimulation and muscle adaptability experiments.
The astronauts used visual coordination testing devices to complete eye-hand coordination tests, including point-to-point tracking and finger movements in mid-air. Ground researchers are expected to use the results to study changes in the stability, accuracy and coordination of the astronauts' fine motor control skills during spaceflight, providing valuable references for future mission procedures and human-machine interface design.
Guided by traditional Chinese medicine theories, the astronauts used portable acupoint stimulation devices for electrical stimulation and completed evaluation forms afterward. This research aims to understand how acupoint stimulation can regulate cardiovascular function and prevent muscle atrophy in microgravity conditions.
In the muscle adaptability experiments, the crew conducted tests on Achilles tendon stiffness, lower-limb kinematics and foot pressure using specialized equipment to gather data on changes in muscle structure and function. Ground researchers will compare pre-flight and post-flight data to clarify the biomechanical effects of long-term weightlessness and in-orbit exercise on the lower limbs.
Additionally, the astronauts underwent regular medical checks, such as body mass measurements, to monitor their health. They also organized supplies, managed waste, and carried out routine cleaning tasks to maintain the space station's living environment.
