BEIJING, Feb. 2 (Xinhua) — The Shenzhou 21 crew members aboard China's Tiangong space station have successfully completed their first three months in space, with all planned tasks completed smoothly, according to the China Manned Spacecraft Administration (CMSA).
On Sunday evening, a video report from China Media Corporation showed that to combat the physical effects of weightlessness, the crew, consisting of mission commander pilot Zhang Lu, flight engineer Wu Fei, and payload specialist Zhang Hongzhang, conducted a lower limb muscle stimulation test.
Using specialized equipment such as bionic adhesive boots, they trained to stimulate their leg muscles and collected data to study muscle adaptation in space.
In the field of space medical research, they have made progress in a pharmacokinetics project that studies how the human body metabolizes medications in space. To do this, they collect saliva samples and send them back to Earth for analysis, providing important data for managing the use of medications in space.
The three cosmonauts also completed a series of human psychology tests, including assessments of human-computer trust, emotional state in orbit, and decision-making ability in emergency situations.
In the field of physical sciences related to microgravity, crew members performed maintenance and repair of experimental equipment. According to the report, this process included cleaning and replacing samples inside a containerless experimental cabinet—a device that holds materials in zero gravity to study their properties without the influence of a container.
Beyond scientific experiments, regular health monitoring remains a priority, as a disciplined exercise regimen in orbit is key to ensuring crew members remain in optimal condition throughout the mission.
The cosmonauts have already undergone numerous medical examinations, including dynamic electrocardiograms, blood pressure monitoring, ultrasound scans, and bone density measurements, which have shown that they are in good health, the report notes.
The Shenzhou-21 manned spacecraft was launched from the Jiuquan Satellite Launch Center in northwest China on October 31, 2025. -0-
