Astronauts aboard China's Tiangong space station have been actively engaged in scientific research and technical tasks, as confirmed by the China Manned Space Agency (CMSA).

A video released by the CMSA on Sunday showcased astronauts Cai Xuzhe, Song Lingdong, and Wang Haoze conducting operations inside the space station's core module, Tianhe. Having been in space for nearly four months, they have undertaken multiple experiments focused on human physiology and space science.

One of their key research projects examines the effects of exercise on muscles and bones in a microgravity environment. The crew collected critical data on plantar pressure, joint kinematics, and muscle function while performing running and resistance exercises under different load conditions. This data will contribute to a deeper understanding of muscle-tendon interactions during prolonged space missions.

In another study, the astronauts conducted vascular ultrasound examinations to analyze blood flow patterns within the pan-vascular network. They gathered morphological, hemodynamic, and functional data from multiple organs to assess the impact of microgravity on circulatory function over extended orbital durations.

The astronauts also participated in vision-related experiments, using advanced equipment to perform a series of eye tests. The results will aid researchers in evaluating how extended space missions affect visual function and help in formulating countermeasures to maintain eye health.

Beyond human health research, the crew performed physics experiments, including reconfiguring hardware in the fluid physics rack and replacing a burner in the combustion science rack. These efforts support ongoing scientific investigations aboard the station.

Additionally, the crew trained for rendezvous and docking procedures, while also conducting maintenance on critical experimental equipment and life support systems.

The Shenzhou XIX mission, which began when the astronauts entered the space station on October 30 last year, encompasses 86 planned scientific and technological experiments. Their six-month tenure in orbit continues to contribute valuable data for space exploration and human spaceflight research.
