Shenzhou-19 Crew: Four Months of Space Experiments | China Space Station
China's Shenzhou-19 astronauts aboard the country's Tiangong Space Station have now spent four months in orbit, successfully conducting a series of scientific experiments while maintaining good physical and mental health, according to China's Manned Space Agency (CMSA).
Over the past week, the Shenzhou-19 trio has made headway in space science experiments and tests, inboard equipment maintenance and health management.
In the field of space medicine, the crew utilized a Raman spectrometer to carry out in-orbit nutritional metabolomics research. Through analysis of metabolic components in urine samples, they reported findings that help refine the existing evaluation systems and establish a specialized methodology for monitoring astronauts' nutritional status throughout the mission.
To study the impact of the space environments on biological rhythms and sleep, the astronauts wore activity tracking devices and heart rate monitors to gather data. The results are expected to offer key insights into sleep-wake cycles, heart rate variations and sleep quality under long-term spaceflight conditions.
To observe astronauts' psychological and behavioral performance, the crew completed in-orbit emotional state tests and emergency decision-making assessments. These efforts will shed more light on the impact of long-duration spaceflight on emotional well-being and decision-making capabilities.
In addition, the astronauts successfully conducted experiments in space materials science and microgravity combustion science, and replaced experiment samples in the container-free lab cabinet, among other tasks.
Last week, the crew completed a comprehensive inventory count of space station supplies, including clothing, work materials, medicine and medical monitoring consumables. They also tested recreational equipment while conducting routine inspections and maintenance of the station's regenerative life support systems.
To ensure wellness and good health during their mission, the astronauts underwent routine medical checkups and lung function tests as scheduled. Traditional Chinese medicine (TCM) diagnostic instruments including TCM four-diagnostic auxiliary apparatus and bone density scanner were also applied for health assessments.
They also engaged in regular exercises using specialized equipment, including a space treadmill, wrist exerciser and grip trainer to counter bone and muscle loss in microgravity.
The Shenzhou-19 crew, including the country's first female space engineer, was sent into space on October 30, 2024 for a six-month mission. It includes 86 space science research and technology experiments, as announced by CMSA prior to the launch.
