shenzhou-20 Astronauts Push Boundaries of Space Medicine Research Aboard Tiangong

Beijing, June 16, 2025 – Living and working hundreds of miles above Earth has become a reality for the Shenzhou-20 crew, comprised of Chen Dong, Chen Zhongrui, and Wang Jie. aboard the Tiangong Space Station, these astronauts are not just observing; they’re actively engaged in groundbreaking research.

Their “space business trip,” as highlighted in a recent video by CCTV, China’s state television broadcaster, is filled with critical scientific work, meticulous health checks, and essential maintenance of the station. All these efforts pave the way for the future of space exploration.

Astronauts in Good Condition as Space Medicine Research Advances

The astronaut trio, led by veteran Chen Dong, launched into orbit on April 24 for a six-month mission. According to CCTV, the crew is in excellent condition, and their multi-disciplinary space science experiments are progressing smoothly.

One of the primary focuses over the past week has been intensive space medicine research. The team delved into the core aspects of how microgravity affects cognitive function.

• Teamwork dynamics
• Self-awareness in isolation
• Astronauts’ perception of motion and depth

These investigations are essential for ensuring safe operations during spacewalks and the accomplished completion of complex tasks in the challenging environment of space.

Vascular health and Coordination Under Microgravity

The astronauts also conducted routine vascular ultrasound scans to monitor changes in cardiovascular function over time. Furthermore, they employed specialized equipment to detect subtle shifts in control and coordination during precise tasks, such as handling equipment and processing samples.

Did You know? Astronauts can experience bone loss at a rate of 1% to 2% per month in space, requiring rigorous exercise regimens to mitigate these effects.

Exploring life Science: Microgravity’s Impact on Microorganisms

In the realm of life science, the Shenzhou-20 crew concentrated on an experiment studying the “effects and mechanisms of space microgravity on microorganisms.” In Tiangong’s biotechnology experiment rack, astronauts observed the growth, developmental patterns, and bioactive compound synthesis of Streptomyces bacteria in a weightless environment.

This pioneering research is expected to uncover novel biological adaptations and may lead to significant applications in space-based pharmaceutical research, potentially revolutionizing drug development for both space and Earth applications.

The crew meticulously collected liquid cultures, preserving them for their eventual return to Earth for further analysis.

Maintaining Health and Fitness in Zero Gravity

Besides their scientific endeavors, the crew dedicates time to rigorous exercise to counteract the physical toll of microgravity. The video shows the astronauts running on a treadmill inside the space module.

Beyond exercise, astronauts undergo regular checkups, including heart monitoring and blood pressure tracking.

Notably, they also participate in unique health assessments rooted in traditional Chinese medicine principles.

Pro Tip: Maintaining a balanced diet rich in vitamins and minerals is crucial for astronauts to combat weakened immune systems and maintain bone density during space missions. Learn more about essential nutrients.

Tiangong Space Station: A Hub for scientific Finding

China’s space station has now facilitated over 200 scientific projects, with nearly 2 tonnes of scientific materials and applied equipment transported to orbit and almost 100 experimental samples returned to Earth, according to the China Manned Space Agency.
