Shenzhou-19 Crew Advances Space Science Aboard Tiangong Station
China’s Shenzhou-19 astronauts have achieved key scientific milestones during their mission aboard the Tiangong space station. The crew has spent over 150 days in orbit, focusing on neuroscience, medicine, and microgravity physics.
Brain Research in Space: Understanding Cognitive Responses
Astronauts Cai Xuzhe, Song Lingdong, and Wang Haoze conducted several neuroscience experiments using electroencephalogram (EEG) devices. These studies aim to understand how gravity influences visual-motor processing. The findings may reveal how humans perceive spatial relationships in microgravity and examine how brainwave-based music therapy affects cognitive control during long space missions.
The data collected will support future research on human brain function in space and could help prepare astronauts for longer missions, such as trips to the Moon or Mars.
Improving Life and Design on the Space Station
The crew also provided detailed feedback about daily life in orbit. They recorded their experiences using video logs and completed questionnaires. Topics included livability, the usability of the space station’s systems, and human-machine interface feedback.
This input allows engineers and designers on Earth to refine spacecraft layouts and improve systems for future missions. The aim is to make space environments more comfortable and efficient for astronauts.
Progress in Medical and Microgravity Experiments
In medical research, the astronauts completed studies related to pharmacokinetics, helping shape how medication is used during long missions. They also underwent regular health checks, including electrocardiograms, lung function tests, and blood pressure monitoring, while practising countermeasures to offset weightlessness.
In space technology, the team worked on the reverse Brayton cryocooling experiment, essential for future deep-space missions. The system, based on ultra-fast gas bearings, will support thermal control in extreme environments.
Microgravity physics experiments also continued. The crew replaced samples and carried out vacuum and gas exhaust operations in high-temperature and fluid physics labs.
Shenzhou-19 Environmental Monitoring and Routine Maintenance
Maintaining the space station environment remained a key task. The astronauts checked airflow, monitored temperature, and ensured air cleanliness. They also carried out routine inspections and maintenance on vital systems.
The Shenzhou-19 spacecraft launched on 30 October 2024 aboard a Long March-2F rocket from the Jiuquan Satellite Launch Centre in northwest China.
