Shenzhou-20 Crew Continues Work on Experiments | China Space Station

⁠⁠⁠⁠⁠⁠⁠The Shenzhou-20 crew has been carrying out a series of scientific experiments in orbit two months after docking with China's Tiangong Space Station on April 25, 2025.

In one notable experiment, astronauts Chen Dong, Chen Zhongrui, and Wang Jie conducted China's first in-orbit flatworm regeneration study. Using a small-scale universal biological module in the life ecology experiment cabinet, the crew explored how space microgravity and radiation affect flatworm regeneration at both morphological and physiological levels. The study is expected to deepen understanding of regenerative mechanisms at the organismal level. 

On May 22 at 16:49 Beijing time, the astronauts completed their first series of extravehicular activities (EVAs). This marked the 20th EVA since the construction of China's space station in 2021. Assisted by the space station's robotic arm and a ground team in Beijing, Chen Dong and Chen Zhongrui, in close collaboration with Wang Jie, exited the space station complex through the node cabin of the Tianhe core module. The three astronauts worked around eight hours to complete multiple tasks, including the installation of space debris protection devices that had earlier been deployed through the cargo airlock cabin and transferred to an intermediate position by the robotic arm, and the inspection of extravehicular equipment and facilities.

Recently, the crew has also conducted tests on several cognitive and coordination-related projects, including studies on trust and collaboration mechanisms, visuomotor gravitational representation, metacognitive monitoring, and spatial relationship cognition under microgravity. Using diagnostic ultrasound, they examined vascular conditions, and carried out precision grip and memory-based tasks using motion measurement devices. They also explored how microgravity affects microorganisms, particularly streptomyces, examining growth, differentiation, population succession, and bioactive compound synthesis using the station's biotechnology experiment cabinet.

All three astronauts remain in good health, and mission-related experiments and operations are progressing steadily.
